            More than 50 years have been wasted in one of the most important and fundamental branches of science and
            medicine, for reasons that are highly ideological and political. Rather than studying the regeneration of
            organs and tissues, and recognizing its obvious importance in healing as well as in understanding the nature
            of life, much of the last century was devoted to the defamation of the researchers who were making real
            process in the field. Despite many demonstrations that regeneration can occur in adult mammals, students
            were taught that it happens only in lower vertebrates. I think it's important to look closely at the
            ideology responsible for this great loss.
        </p>

        <p>
            Warburg and Szent-Gyorgyi, in thinking about cancer, emphasized that growth is the primordial function of
            all cells, and that the differentiated functions of complex organisms involve restraints of that primitive
            function, imposed by a system that has developed through time.
        </p>
        <p>
            Seen with this orientation, regeneration is the spontaneous result of the disappearance of restraint. The
            reproduction of a whole plant from a twig, or clone, was a process known for thousands of years. Any part of
            the plant contains the information needed for making a whole plant. More than thirty years ago, cells from a
            tumor were added to the cells of a normal embryo, and the animal that matured from the embryo-tumor mix was
            normal, and had traits of both lineages, showing that the tumor cells had retained the genetic information
            of a complete healthy organism, and just needed a different environment in which to realize their full
            potential.
        </p>
        <p>
            One of the currents of medical thinking, from classical times through Paracelsus to homeopathy and
            naturopathy, has been a confidence in the capacity of the organism to heal itself. But "modern" medicine has
            arrogated to itself the "healing power," with terrible results, mitigated only by their occasional reluctant
            acceptance of fragments of sane organismic thinking, such as recognizing the importance of nutrition, or of
            keeping sewage out of the drinking water. Research into methods to support the organism's natural
            restorative powers has been ridiculed and suppressed.
        </p>
        <p>
            We are immersed in the propaganda of modern medicine, and part of that propaganda involves the confabulation
            of a history of science that supports their practice and their ideology. The real history of science won't
            be found in science textbooks.

            Mainstream medical treatments are based on some fundamentally absurd scientific ideas. The advent of
            experimental animal cloning and the industrialization of genetic engineering have undercut the most
            important biological doctrines of the 20th century, but the processes of critical thinking haven't made
            headway against most of the traditional medical stereotypes. Cloning shows that all cells are potential
            "stem cells," but this fact co-exists with the Hayflick doctrine, that says, essentially, that no cell is a
            stem cell.
        </p>
        <p>
            The ideology of culturally significant "intellectuals"--scientists, professors, neurobiologists, linguists,
            philosophers, oncologists, geneticists--in the US is deeply influenced by the dualism and mechanistic
            materialism of Rene DesCartes.
        </p>

        <p>
            The denial that animals can think or understand language, the claim that babies or animals don't feel pain,
            or that heart cells and brain cells can't divide, or that somatic cells lack the genetic capacity to be
            cloned, or that they are intrinsically mortal, limited to a maximum of 50 cell divisions--these absurdities
            of 20th century biology and medicine all resulted from an abject commitment to the mechanistic doctrine of
            matter and life promoted or invented by DesCartes.
        </p>
        <p>
            I doubt that DesCartes really invented anything, because, by the evidence of his writing, he wasn't an
            intelligent man, but he placed himself politically in such a way that his arguments were acceptable to many
            influential people, and they continue to be acceptable to authoritarian and elitist factions even today.
        </p>
        <p>
            In the 16th and 17th century the cultures of England, Holland, and France were increasingly dominated by
            business interests. People who had money to invest wanted to see the world as an orderly, predictable place,
            and they found that many of the ideas of the ancient Greeks were useful. Mathematics was needed to calculate
            interest rates, insurance premiums, and, for the military, the trajectories of missiles. In an orderly
            world, allowance for a little random variation helped to save the perfection of the general rule.
        </p>
        <p>
            In this environment, theological thinking began retrenching its doctrine, to make it more acceptable to the
            increasingly powerful commercial people. The clockwork universe of DesCartes' time, in which a perfect world
            that operated according to perfect natural laws had been divinely created, gradually became theologically
            acceptable during the 18th and 19th centuries. In the 18th century, the Deists were the most famous
            embodiment of the idea, and then in the 19th century their place was taken by the Catastrophists, who
            claimed that the fossils which seemed to show evolutionary change of species actually represented species
            that had been created along with those now existing, but that had been destroyed by catastrophes, such as
            Noah's flood. By the end of the 19th century, the president of an American university recognized that
            theological compromises could prevent his undergraduates from rejecting religion entirely, and forbade
            sermons against evolution.
        </p>

        <p>
            There were many biologists who insisted that evolution of new species was analogous to the development of an
            individual, and that both revealed an adaptive capacity of the living substance. In this view, the adaptive
            growth of an individual in a new environment revealed novel solutions to new problems, and showed an innate
            inventiveness and intelligence in the process of growth and adaptation. The appearance of new species was
            thought to represent the same sorts of adaptive processes.
        </p>
        <p>
            Erasmus Darwin (grandfather of Charles) was an evolutionist of this sort, but because of political and
            theological pressure, he kept relatively quiet about his beliefs. There was an underground culture, in which
            an evolutionary view of the world was accepted, but these views were seldom published, because of
            increasingly stringent censorship. Because of censorship, poetry, letters, and diaries, rather than academic
            and scholarly works, give us the true picture of 18th century and early 19th century scientific culture.
        </p>
        <p>
            The scientists who wanted their work to be acceptable to those in power found ways to work with the
            Cartesian mechanical view of the world, building on the Deists' compromise, which had succeeded in removing
            the supernatural from nature. As the fossil evidence of evolution became inescapable, around the time of
            Charles Darwin's work, those who wanted to bring evolution into the mainstream of culture found that the
            Catastrophism of the creationists could be adapted to their purposes, with only slight modification.
        </p>
        <p>
            The doctrine of Thomas Malthus, who argued that war, famine, and disease were beneficial for those who
            survived, by decreasing the competition for limited resources, became a near equivalent to the catastrophic
            floods that the creationists had invoked to explain the geological record that contained evidence of many
            extinct animals. <strong>The doctrine of Malthus, like that of the Catastrophists, made loss, deletion, and
                destruction into a central device for explaining the history of the world.</strong>
        </p>
        <p>
            Both of the Darwins had accepted the idea that many biological changes were adaptive, rather than random,
            but the new practical compromise doctrine introduced the idea that changes were just "random variations."
            The essentially mechanical nature of the world was preserved, because "chance" occurrences could be dealt
            with, and didn't involve anything supernatural. <strong>The function of the environment wasn't to add
                anything to life (that would have been to assert that there were creative powers other than those of the
                Creator), but simply to eliminate the inferior individuals that appeared as the result of random
                changes.</strong>
        </p>
        <p>
            Gregor Mendel applied the principle of chance to explaining the inheritance of certain traits, and showed
            that "traits" were passed on unchanged, even when they weren't visible. His ideas were published and were
            acceptable to the scientific mainstream of his time. Traits were determined by "factors" that were passed
            on, unchanged, from parents, and biological variation was explained by varied mixing of factors which in
            themselves were unaffected by the organism or the environment. Genetic determinism was safely compatible
            with creationism.
        </p>

        <p>
            Shortly after Mendel's death, August Weismann began a campaign to put a stop to the claims of those who,
            like the Darwins and Lamarck, saw adaptive development of organisms as an essential part of the evolution of
            species.
        </p>
        <p>
            Weismann was essentially a propagandist, and his first fame was the result of "disproving" Lamarck by
            cutting the tails off more than 1500 mice, and observing that their offspring were born with tails. The
            reason the inheritance of acquired traits was impossible, he said, was that the "germ line" was perfectly
            isolated from the rest of the organism. The differentiated tissues of the body were produced by the
            selective loss of information from the nuclei of cells in the embryo. The cells of the germ line were
            immortal and contained all the information needed to produce an organism, but no other cell of the organism
            was complete.
        </p>
        <p>
            Complexity was produced by deletion, and this was the basis for arguing that, if even the development of an
            individual was nothing but a passive unfolding of inherited properties, much like unpacking a trunkful of
            clothes, then there could be no adaptively acquired traits, and certainly no inheritance of something which
            didn't exist. Changes in an individual were simply accidents, such as having a tail amputated, and so the
            whole issue of the origin of complexity was safely left to a primordial creation.
        </p>

        <p>
            Weismann and his arguments were famous in Europe and the US, and formed the background for the ideas known
            as neo-Darwinism. His "isolation of the germ line" was the earliest version of the Central Dogma of
            molecular biology, namely, that information flows only from DNA to RNA to protein. His doctrine, of
            complexification through deletion, is the epitome of the greatest dogma of modern times, expressed in
            doctrines from Catastrophism through the second law of thermodynamics and the theory of the Big Bang, down
            to Hayflick's Doctrine of the mortality of somatic cells. All these are consequences of the Cartesian and
            Deistic separation of intelligence from matter.
        </p>
        <p>
            Regeneration is one of the most vivid examples of the intelligence of living substance.
        </p>
        <p>
            Given a natural tendency of cells to multiply, the interesting thing about regenerative healing is the
            question of why the new growth of tissue sometimes differentiates to fit appropriately into its
            surroundings, but sometimes fails to differentiate, becoming a tumor.
        </p>
        <p>
            With aging, the regenerative process declines, and the process of tissue rebuilding slows. Against a
            background of reduced regenerative ability, tissue growth sometimes produces tumors, rather than renewed
            healthy tissue. When tumors are grafted onto the amputated tail stump of a salamander, which has good
            regenerative ability, the tumor is transformed into a tail, by its envirornment, or morphogenic field. The
            "cancer problem" is essentially the problem of understanding the organizing forces of the organism. The
            aging problem is another aspect of the same problem.
        </p>

        <p>
            Traditionally, biologists had studied anatomy, physiology, embryology or development, and taxonomy or the
            classification of organisms. The growth of knowedge early in the 20th century was suddenly seeming to
            confirm the physiological, adaptive view of organisms that Lamarck had held. C.M. Child, Joseph Needham,
            Alexander Gurwitsch, and L.V. Polezhaev were demonstrating the primacy of a formative process in biology.
            Polezhaev and Vladimir Filatov were studying practical means of stimulating regeneration as a medical
            technique.
        </p>
        <p>
            Until the beginning of the second world war, the study of regeneration and the pattern-forming processes in
            embryology were the liveliest parts of biological research. Gestalt psychology was being developed at the
            same time, with a similar emphasis on patterns and wholes.
        </p>
        <p>
            But Weismannism and neo-Darwinism, largely embodied in the person of the geneticist T.H. Morgan,
            deliberately set out to kill that line of biological research. Gestalt psychology was similarly eliminated
            by the Behaviorists.
        </p>
        <p>
            One of Morgan's closest associates, his student and colleague A.H. Sturtevant, said that "Morgan's
            objectives, what he was trying to get at in general in his biological work was to produce mechanistic
            interpretations of biological phenomena. One of the things that irritated him most was any suggestion of
            purpose in biological interpretation. He always had some reservations about the idea of natural selection,
            because it seemed to him to open the door to interpretations of biological phenomena in terms of purpose. He
            could be talked into the conclusion that there was nothing that wasn't strictly mechanistic about this
            interpretation, but he never liked it. And you had to talk him into it again every few months." (Sturtevant,
            A. H., <em>Genetics, Vol. 159,</em> 1-5, September 2001, Copyright 2001, Reminiscences of T. H. Morgan.)
        </p>

        <p>
            Whatever his motives, Morgan was known to have prevented his students (including C.M. Child) from publishing
            work that supported a holistic view of the organism. After Morgan's death, there was an intense and
            widespread campaign to suppress any approach to biology other than the "new synthesis," neo-Darwinism, with
            its doctrine of mechanistic genetic determinism and its doctrine of random variation. A developmental
            biologist, J.M. Opitz (1985), commented that <strong>"in one of the most astounding developments in Western
                scientific history, the gradient-field, or epimorphic field concept, as embodied in normal ontogeny and
                as studied by experimental embryologists, seems to have simply vanished from the intellectual patrimony
                of Western biologists."</strong>
            <strong> </strong>
        </p>
        <p>
            Formative processes are necessarily multidimensional, and that makes calculation and analysis very complex.
            To a great extent, the geneticists were motivated to study bacterial genes, rather than vertebrate embryos,
            by the principle that motivated the drunk to look for his car keys under the street lamp, even though that
            wasn't where he lost them, because the light made it easier to look there.
        </p>
        <p>
            Bacteria are easy to study because they lack the complexity that makes it hard to study an embryo or an
            animal. The language used in genetics textbooks shows not only that bacteria are treated by geneticists as
            if they were one or two dimensional, but that the concepts developed for bacterial genetics have been
            extrapolated to use in describing complex organisms: "<strong>Genes interact</strong> to establish the body
            axis in Drosophila. Homeotic <strong>Genes control</strong> pattern formation along the anterior-posterior
            body axis." (<em>Essentials of Genetics,</em> M. Cummings and W. Klug, Prentice Hall, 2004.)
        </p>

        <p>
            One of the basic distinctions in embryology is in the way the cells divide after the egg is fertilized.
            Oysters and earthworms have spiral cleavage, sea urchins and people have radial cleavage. Several decades
            ago an experimenter was transferring a nucleus from an egg of an animal with radial cleavage, I think a sea
            urchin, into the enucleated egg of a snail, with spiral cleavage. The nucleus transplanted across such a
            great difference in phyla didn't sustain maturation of the animal, but it did permit development to proceed
            for several rounds of cell division, and the pattern of cell division, or cleavage, and embryonic
            development always followed the pattern of the phylum to which the egg cytoplasm belonged, never the pattern
            of the phylum from which the nucleus was derived. The genes in the nucleus, obviously, weren't directing the
            basic pattern formation of the embryo.
        </p>
        <p>
            One-dimensional bacterial genetics can be used to "explain" multidimensional systems, but it can't be
            expected to make useful predictions.
        </p>
        <p>
            The idea of complexity, or of multidimensionality, has often been analyzed in terms of "fields," by analogy
            with a magnetic field, as some property, or properties, that extend beyond any individual part, giving some
            coherence to the parts. Lamarck was concerned with understanding ensembles of particles and cells, but in
            his time electricity and heat were the only principles that physics provided that helped to illuminate the
            nature of living organisms. At the end of the 19th century, though, the physicist J.C. Bose was noticing
            that all of the properties of life that had interested Lamarck and Buffon--irritability, sensation,
            contraction, memory, etc.--had their close analogs in non-living substances. Bose, who invented the radio
            detector that was the core of Marconi's apparatus, found that, in the presence of an electromagnetic field,
            particles of a substance, such as finely powdered metal filings, cohered into a unified whole. An otherwise
            invisible, undetectable "field" which in Lamarck's time might have been known as one of the "subtle fluids,"
            was able to organize a myriad of inert particles into a unified whole.
        </p>
        <p>
            In the early 1920s, Bungenberg de Jong and A.I. Oparin showed how solutions of organic substances could
            spontaneously organize themselves into complex systems, with differentiated parts. A Russian embryologist,
            Alexander Gurwitsch, found that the parts of an organ or embryo could exert their stimulating or organizing
            influence on other cells even through a piece of glass, and by using different types of filter, he
            identified ultraweak ultraviolet rays as a medium of communication between cells. F.-A. Popp and others are
            currently studying the integrating functions of ultraweak light signals. Guenter Albrecht-Buehler (who has
            an interesting website called Cell Intelligence) is investigating the role of pulsed infrared signals in
            cell communication.

            Electrical fields produced by cells, tissues, and organisms have been shown to influence cellular metabolism
            and physiology, and to influence growth patterns. Closely associated with cellular electrical fields are
            fields or gradients of pH and osmolarity, and all of these fields are known to affect the activity of
            enzymes, and so to create environments or fields of particular chemical concentrations.
        </p>
        <p>
            A phenomenon that was well known in the 1930s, when developmental fields were still a familiar part of
            scientific discussion, was the "cancer field." Before a cancer developed in a particular area, the area
            showed progessive changes, away from normal function and structure, toward the cancer physiology.
        </p>
        <p>
            In the embryonic state, damaged tissues regenerate quickly. The metabolism of an embryo or fetus is highly
            oxidative, converting glucose rapidly to carbon dioxide and water. Both carbon dioxide and water are
            important regulators of cellular metabolism and function, and the concentrations of both of them decrease
            systematically with maturity and aging. Both are involved with the most basic aspects of cellular
            sensitivity, responsiveness, and organization.
        </p>

        <p>
            To resume the scientific tradition that has "simply vanished," I think we have to recover our ability to
            think about organisms generally, leaving aside as many of the concepts of genetics as possible (such as
            "gene," "operon," "receptor"; "the gene" has never been more than an ideological artifact), because they so
            often falsify the most important issues. The organization of tissues and organs, and their functional
            properties, should be the focus of attention, as they were for Lamarck around 1800, and for Johanes Muller,
            who in 1840 saw cancer as a problem on the level of tissue, rather than cells. For Lamarck, sensitivity and
            movement were the essential properties of the living substance, and J. C. Bose showed reasons for believing
            that the characteristics of life were built on related properties of matter itself.
        </p>
        <p>
            Sensitivity, the ability to respond appropriately to the environment, is probably a missing factor in the
            development of a tumor. The ability to become quiescent, to quietly participate in the ensemble of cells, is
            an essential feature of the sensitivity and responsiveness of the cells of complex organisms. The factors
            that support organized appropriate functioning are the factors that help cells to inhibit the excitatory
            state. If the keys of an accordion or organ didn't spring back after the musician pressed them, the
            instrument would be unplayable. In extreme physiological states, such as epilepsy or malignant hyperthermia,
            nerves or muscles become incapable of relaxing. Insomnia and muscle cramps are milder degrees of a defective
            relaxation process. Excitoxicity and inflammation describe less generalized cases of a similar process, in
            which there is an imbalance between excitation and the restorative ability to stop the excitation. Prolonged
            excitation, resulting in excessive fatigue, can cause a cell to disintegrate, in the process of cell death
            called apoptosis, "falling away."
        </p>

        <p>
            In the experiments of Polezhaev and Filatov, the products of cell disintegration were found to stimulate the
            birth of new cells (possibly by blocking a signal that restrains cell division). This process has been found
            in every organ that has been examined appropriately. It amounts to a "streaming regeneration" of the
            organism, analogous to the progressive creation of Lamarck's view. G. Zajicek has demonstrated an orderly
            "streaming" renewal in several organs, and even the oocytes (which in the Weismannian dogma were formed at a
            very early stage during embryonic development, and were perfectly isolated from the cells of the mature
            body) have recently been shown to be continually regenerated in adult ovaries.
        </p>
        <p>
            "Stem" cells turn out to be ubiquitous, and the failure of regeneration and restoration seems to be
            situational. In the 1950s a magazine article described the regeneration of a finger-tip when the wound was
            kept enclosed. Decades later, friends (one a child, the other a man in his forties) had accidental
            amputations of a finger-tip, down to the cuticle so that no visible nail remained. The boy's mother fitted
            his finger with the tube from a ballpoint pen, and the man used an aluminum cigar tube as his "bandage."
            Within a few weeks, their fingers had regenerated to their normal shape and length. I think the closed
            environment allows the healing tissues to be exposed to a high concentration of carbon dioxide, in
            equilibrium with the carbon dioxide in the capillaries, and to a humid atmosphere, regulated by the osmotic
            or vapor pressure of the living tissues.
        </p>

        <p>
            Under ordinary conditions, the creation of cells and the dissolution of cells should be exactly balanced.
            The coordination of these processes requires a high degree of coherence in the organism.
        </p>
        <p>
            Simple increase of water in the vicinity of a cell increases its tendency to multiply, as well as its
            excitability, and hypertonicity restrains cell division, and reduces excitability. Carbon dioxide, besides
            helping proteins to release water, appears to increase the ability of proteins and cells to respond to
            morphogenetic fields. Carbon dioxide is the most universal agent of relaxation, restoration, and
            preservation of the ability of cells to respond to signals. Progesterone is another very general agent of
            restorative inhibition.
        </p>
        <p>
            The study of regeneration and "stem cells" is helping to illuminate the general process of aging, and to
            provide very practical solutions for specific degenerative diseases, as well as providing a context for more
            appropriate treatment of traumatic tissue injury.
        </p>
        <p>
            In aging, the growth and regenerative processes are slowed. There is some evidence that even cell death is
            slower in old age, at least in some tissues. Since animals with the highest metabolic rate live the longest,
            the slowing rate of metabolism during aging probably accounts for those changes in the rate of cell renewal.
            The continually streaming regeneration of tissues is part of the adaptive process, and it is probably
            intensified by stress.
        </p>
        <p>
            The ability to sleep deeply decreases in old age, as a generalized inflammatory, excitatory state of stress
            develops. With progressive weakening of restorative cellular relaxation (inhibition), cells become more
            susceptible to disintegration. It's well established that bone loss occurs almost entirely during the night,
            and since the catabolic hormones generally affect soft tissues as well as bones, the atrophy of soft tissues
            ("sarcopenia") of aging is also probably a process that occurs mostly during the night. Mediators of
            inflammation are at their highest during the night (Cutolo and Masi, 2005). But during the period of growth,
            the length of bones seems to increase mostly during the night (Noonan, et al., 2004). My interpretation of
            this is that the stress of darkness accelerates biological processes, whether the process is mainly
            constructive or mainly destructive.
        </p>

        <p>
            The effect of light supports efficient oxidative energy production, which supports the protective inhibitory
            processes, by increasing ATP and CO2, and decreases the inflammatory mediators that intensify stress. If
            organized cellular luminescence is required for a proper balance, then the random luminescence produced by
            lipid peroxidation (which may be more intense at night--Diaz-Munoz, et al., 1985), might be an important
            factor in disrupting the balanced streaming of regeneration. Free radicals, whatever their source, absorb a
            broad spectrum of radiation, and would block luminous signals of all frequencies. Isoprene, produced mainly
            at night (Cailleux and Allain, 1989), is another ultraviolet absorber that might account for nocturnal
            regulatory disorders.
        </p>
        <p>
            The age pigment, lipofuscin, is known to contribute to degenerative diseases, but the nature of its toxicity
            has never been established. Its absorptive and fluorescent properties would be very likely to interfere with
            mitogenetic and morphogenetic radiation. Polyunsaturated fats are the main component of lipofuscin, and
            these fats in themselves can absorb ultraviolet light. When those fats are present in the skin, exposure to
            ultraviolet light accelerates the aging of the skin. Free fatty acids often increase during the night, under
            the influence of hormones such as adrenaline and growth hormone.
        </p>
        <p>
            A single night of poor sleep probably causes significant anatomical damage to the streaming cellular systems
            that will be repaired over the next few days if a high level of energy metabolism can be combined with a
            sufficient amount of deep sleep. The things that optimize energy and sleep form the background for
            supporting the restorative processes. Salt, glycine, carbon dioxide, progesterone, thyroid hormone and sugar
            all contribute to preserving the organism's energetic reserves by reducing inappropriate excitation.
        </p>
        <p>
            Lamarck's idea that organs developed or regressed according to their use or disuse was often attacked by
            followers of the Weismann-Morgan genetic dogma. In their view, the influence of the environment was limited
            to either preventing or permitting the realization of "the genetic potential." Once that predefined
            potential had been unfolded, the finite and mortal nature of the somatic cells didn't allow for any
            significant changes, except for depletion and death. One of the high points of Weismannian biology came with
            the publication of an article in Science, around 1970, that proposed to explain learning in terms of the
            lifelong loss of brain cells, beginning in humans around the age of 18 months, with a daily loss of 100,000
            cells, which would record experience by selective deletion, the way punching holes in cards had been used to
            enter data into computers. I was present to witness "world class biologists" taking that idea very
            seriously.
        </p>

        <p>
            As Sturtevant mentioned in the quotation above, T.H. Morgan couldn't accept any attribution of
            purposefulness to organisms. In his genetic dogma, changes were only random, and people who denied that were
            denounced as "teleological" (or metaphysical) thinkers. Changes occurred by deletion, not by meaningful
            addition.
        </p>
        <p>
            One of Pavlov's students, P.K. Anokhin, developed the concept of the Functional System in the 1930s, to
            explain the purposive behavior of animals. In the 1950s, Anokhin integrated the endocrinology of stress and
            adaptation into the concept, and F.Z. Meerson continued the work, concentrating on the metabolic and
            structural changes that protect the heart during stress. The simplest view of the conditional reflex
            involves the adaptation of an animal to an external signal, identifying it as the occasion for a particular
            action. Analyzing the Functional System starts with the need of the animal, for example for food, and
            examines the processes that are involved in satisfying that need, including nerve cells, a sense of hunger,
            knowledge of what things are edible, the muscles needed to get the food, and the digestive apparatus for
            assimilating it.
        </p>
        <p>
            When an understanding of stress physiology is combined with the idea of functional systems, the adaptive
            meaning of the use or disuse of certain organs is given a concrete basis. Cortisol mobilizes amino acids
            from muscles that are idle, and makes them available for the synthesis of proteins in the muscles, nerves,
            or glands that are activated in adapting to the stress. The London taxi drivers whose hippocampus grows as
            they learn the locations of the streets are very good examples of the processes described by Meerson,
            Anokhin, and Lamarck, in which the use of an organ in meeting a need contributes to the development of that
            organ. The balance between growth and regression is shifted during adaptive behavior.
        </p>
        <p>
            Exercise physiologists, without mentioning functional systems, have recently discovered some principles that
            extend the discoveries of Meerson and Anokhin. They found that "concentric" contraction, that is, causing
            the muscle to contract against resistance, improves the muscle's function, without injuring it. (Walking up
            a mountain causes concentric contractions to dominate in the leg muscles. Walking down the mountain injures
            the muscles, by stretching them, forcing them to elongate while bearing a load; they call that eccentric
            contraction.) Old people, who had extensively damaged mitochondrial DNA, were given a program of concentric
            exercise, and as their muscles adapted to the new activity, their mitochondrial DNA was found to have become
            normal.
        </p>

        <p>
            There are probably the equivalents of constructive "concentric" activity and destructively stressful
            "eccentric" activity in the brain. For example, "rote learning" is analogous to eccentric muscle
            contraction, and learning by asking questions is "concentric." "No bird soars too high, if he soars with his
            own wings." Any activity that seems "programmed" probably stifles cellular energy and cellular intelligence.
        </p>

        <p>
            When activity is meaningful, and is seen to be meeting a felt need, the catabolic and anabolic systems
            support and strengthen the components of the functional system that has been activated. Everything we do has
            an influence on the streaming renewal of the adaptive living substance.
        </p>
        <p>
            There are many therapeutic techniques that could be improved by organized research, for example,
            investigating the interactions of increasing carbon dioxide, reducing atmospheric pressure, supplementing
            combinations of salt and other minerals, balancing amino acids and sugars, and varying light exposure and
            types of activity. The dramatic results that have occasionally been demonstrated (and then suppressed and
            forgotten) are just a hint of the possibilities.
        </p>
        <p>
            If we keep our thoughts on the living substance, the pervasive ideologies lose their oppressive power.

            synthesis and in 3 hours by initiation of DNA synthesis. Apparently normal nuclear mitosis ensued, but
            cytokinesis was not completed in most cells; this resulted in the formation of binucleate neurons. The
            daughter nuclei each contained the same amount of DNA as the diploid preinduction parental neurons; this
            implies that true mitogenic replication was induced.

            </strong>Hery F, Chouvet G, Kan JP, Pujol JF, Glowinski J. Rats submitted to regular 12 h cycles of light
            and darkness for three weeks were sacrificed at various times of the day. 5-HT, 5-HIAA and tryptophan levels
            were estimated in the fronto-parietal cerebral cortex. Tyrosine and free and total tryptophan levels in
            serum were estimated in parallel. Significant circadian variations in 5-HT and 5-HIAA levels were found in
            cerebral tissues. The peaks of 5-HIAA levels were dectected during the lignt and dark periods respectively,
            the maximal fluctuations being seen between 17.00 h and 21.00 h, two times separating the light off.
            Important significant circadian variations in free and total <strong>serum tryptophan</strong> levels were
            also observed<strong>. In both cases, the maximal levels were found during the middle of the dark
                phase</strong> after the peak of 5-HIAA levels. The circadian rhythm of tyrosine levels in serum was in
            opposite phase with that of tryptophan (free or total). The diurnal changes in tryptophan content in
            cerebral tissues seemed thus related to those found in serum. Taking in consideration results obtained in
            previous studies 16,17 carried out in similar experimental conditions, it was concluded that the parallel
            increase in serum free tryptophan and in tissues 5-HIAA levels seen during the night were not related to a
            stimulation of 5-HT turnover. Indeed 5-HT synthesis is minimal at this time16.

            post-injection, whereas no significant change was seen with injections given in the middle of the
            photophase. No significant change in muscle FFA level was obtained either during the photophase or the
            scotophase when estimated at 90 min postinjection. <strong>With a higher dose (5 mg/kg body weight) of
                melatonin given in the scotophase, on the other hand, a significant increase in both plasma as well as
                muscle FFA levels was obtained at 90 min post-injection but there was no effect on plasma FFA at 20 min
                or 90 min</strong> post-injection in the photophase and at 20 min in the scotophase. It is concluded
            that <strong>

                dentate gyrus of the rat.</strong> Kee NJ, Preston E, Wojtowicz JM. "Certain insults such as epileptic
            seizures and ischemia are known to enhance the rate of neuronal production. We analyzed this phenomenon
            using the temporary occlusion of the two carotid arteries combined with arterial hypotension as a method to
            induce ischemia in rats. We measured the rate of cell production and their state of differentiation with a
            mitotic indicator, bromodeoxyuridine (BrdU), in combination with the immunohistochemical detection of
            neuronal markers. One week after the ischemic episode, the cell production in dentate gyrus was increased
            two- to threefold more than the basal level seen in control animals. <strong>
                Two weeks after ischemia, over 60% of these cells became young neurons as determined by colabeling with
                BrdU and a cytoplasmic protein (CRMP-4) involved in axonal guidance during development. Five weeks after
                the ischemia, over 60% of new neurons expressed calbindin, a calcium-binding protein normally expressed
                in mature granule neurons.</strong> In addition to more cells being generated, a greater proportion of
            all new cells remained in the differentiated but not fully mature state during the 2- to 5-week period after
            ischemia." "The results support the hypothesis that survival of dentate gyrus after ischemia is linked with
            enhanced neurogenesis. Additional physiological stimulation after ischemia may be exploited to stimulate
            maturation of new neurons and to offer new therapeutic strategies for promoting recovery of neuronal
            circuitry in the injured brain."

                sustained-release niacin (Niaspan) and the physiologic rationale for nighttime dosing.</strong> Knopp
            RH. Niacin is the oldest and most versatile agent in use for the treatment of dyslipidemia. It has
            beneficial effects on low-density lipoprotein cholesterol; high-density lipoprotein cholesterol; the
            apolipoproteins B and A-I constituting these fractions; triglyceride; and lipoprotein(a). Together, these
            benefits lead to a diminished incidence of coronary artery disease among niacin users. The chief constraints
            against niacin use have been flushing, gastrointestinal discomfort, and metabolic effects including
            hepatotoxicity. Time-release niacin has been developed in part to limit flushing, and now a nighttime
            formulation (Niaspan) has been developed that assists in containing this untoward effect. In a pivotal
            metabolic study, bed-time administration of 1.5 g time-release niacin was shown to have the same beneficial
            effects as 1.5 g plain niacin in 3 divided doses and to be well tolerated. <strong>Previous studies suggest
                that bedtime niacin administration diminishes lipolysis and release of free fatty acids</strong> to the
            liver; this, in turn, leads to an abolition of the usual diurnal increase in plasma triglyceride, which may
            result in diminished formation and secretion of triglyceride in the very-low-density lipoprotein fraction.

            Cholesterol, longevity, intelligence, and health.
        </h1>

        <strong>
            The biological meaning of cholesterol is just starting to be explored. Everything that doctors know about
            cholesterol is wrong. New information about cholesterol is clarifying important issues in physiology and
            pathology.
        </strong>

        Medical magazines and television stations like to propagate the idea that cholesterol is bad stuff, and as a
        result, that cliche is known to almost every American. Recent journal articles have promoted the idea that "the
        lower the serum cholesterol is, the better" it is for the health of the patient. The theory that heart disease
        is "caused by cholesterol" has gone through several stages, and most recently the use of the "statin" drugs has
        revived it in a radical way. One consistent theme for fifty years has been that people should eat more
        polyunsaturated fat and less saturated fat, to lower their cholesterol, and to avoid butter, cream, eggs, and
        "red meat," because they contain both saturated fat and cholesterol. Often, medical attention is focused on the
        fats in the atheroma, rather than on the whole disease process, including clotting factors, vascular spasms,
        heart rhythm, viscosity of the blood, deposition of calcium and iron in blood vessels, and the whole process of
        inflammation, including the reactions to absorbed bowel toxins. Almost 100 years ago, some experiments in Russia
        showed that feeding rabbits cholesterol caused them to develop atherosclerosis, but subsequent experiments
        showed that rabbits are unusual in responding that way to cholesterol, and that even rabbits don't develop
        atherosclerosis from cholesterol if they are given a supplement of thyroid (Friedland, 1933). By 1936, it was
        clear that hypercholesterolemia in humans and other animals was caused by hypothyroidism, and that
        hypothyroidism caused many diseases to develop, including cardiovascular disease and cancer. There was already
        more reason at that time to think that the increased cholesterol was a protective adaptation than to think that
        it was maladaptive. The strange idea that cholesterol causes atherosclerosis was revived in the 1950s when the
        vegetable oil industry learned that their polyunsaturated oils lowered serum cholesterol. (Many other toxins
        lower cholesterol, but that is never mentioned.) The industry began advertising their oils as "heart
        protective," and they enlisted some influential organizations to help in their advertising<strong>:</strong> The
        American Dietetic Association, the American Heart Association, the US Dept. of Agriculture and FDA, and the AMA.
        Besides the early rabbit research, which didn't make their case against cholesterol and might actually have had
        implications harmful to their argument (since Anitschkow had used vegetable oil as solvent for his cholesterol
        feedings), the oil industry helped to create and promote a large amount of fraudulent and unscientific work. The
        death rate from heart disease in the United States began increasing early in the twentieth century, and it
        reached its peak from about 1950 to 1975, and then began declining. During the decades in which the death rate
        was rising, consumption of animal fat was decreasing, and the use of vegetable oil was increasing. In the
        southern European countries that have been said to show that eating very little animal fat prevents heart
        disease, the trends after the second world war have been the opposite--they have been eating more animal fat
        without an increase in heart disease. The correspondence between heart disease and consumption of saturated fat
        and cholesterol is little more than advertising copy. If people were looking for the actual causes of heart
        disease, they would consider the factors that changed in the US during the time that heart disease mortality was
        increasing. Both increases in harmful factors, and decreases in protective factors would have to be considered.
        The consumption of manufactured foods, pollution of air and water, the use of lead in gasoline, cigarette
        smoking, increased medicalization and use of drugs, psychosocial and socioeconomic stress, and increased
        exposure to radiation--medical, military, and industrial--would be obvious things to consider, along with
        decreased intake of some protective nutrients, such as selenium, magnesium, and vitamins. But those harmful
        factors all had their defenders<strong>:</strong> Who defends socioeconomic stress? All of the social
        institutions that fail to alleviate it. In 1847, Rudolph Virchow was sent to Poland to study the health
        situation there, and when he returned, the highly regarded anatomist, physiologist and pathologist announced
        that the Poles wouldn't have a health problem if the government would stop oppressing them, and institute
        economic reforms to alleviate their poverty. The reforms weren't made, and Virchow lost his job. Other harmful
        factors, such as seed oils, degraded foods, and radiation, have specific, very well organized and powerful
        lobbies to defend them. Despite the growing knowledge about the dangers of polyunsaturated fats, many medical
        articles are still advocating the "official" heart protective diet (e.g., "<strong>... </strong>
        diets using nonhydrogenated unsaturated fats as the predominant form of dietary fat," Hu and Willet, 2002). Some
        dogs alertly look at the thing a person is pointing at, other dogs just sniff the pointing finger. The
        publicists who disregard the complete nutritional and ecological situation, to focus on cholesterol and fat in
        the diet, are like the finger sniffers. Recent articles in the medical and lipids journals are praising the 1950
        work of J. W. Gofman, and the 1914 rabbit studies of N. N. Anitschkow, as the research that revealed cholesterol
        to be the cause of heart disease. Anitschkow and his co-workers, however, understood that their experiment
        hadn't explained human heart disease, and John Gofman, about 50 years after publishing his work on the
        lipoproteins, has done some large studies that could be crucial in disproving the doctrine that has become
        almost a national religion. He has shown that mortality from both heart disease and cancer corresponds very
        closely to the population's exposure to medical services, and specifically to medical radiation. During the peak
        years of heart disease mortality, medical x-rays gave very large doses of radiation with each exposure, and the
        population was also exposed to radioactive fallout from atomic bomb testing (explosions from 1945 to 1963
        produced a peak of heavy fallout that persisted through the 'sixties and into the 'seventies). Around 1971,
        someone noticed that the commercial cholesterol being used in feeding experiments was oxidized, that is, it
        wasn't really cholesterol. Comparing carefully prepared, unoxidized cholesterol with the oxidized degraded
        material, it was found that dietary cholesterol wasn't necessarily atherogenic (Vine, et al., 1998). Dietitians
        often recommend eating poached salmon, rather than "red meat," to lower cholesterol. Experimenters have measured
        the toxic oxidized cholesterol in different foods prepared in a variety of ways. Steaming salmon produced
        several times as much oxidized cholesterol as frying it, because of the longer cooking time that allowed the
        polyunsaturated fatty acids to break down, producing toxins such as acrolein and free radicals that oxidize the
        cholesterol and other components of the fish. The toxic cholesterol content of the steamed salmon was much
        higher than that of beef cooked at a high temperature. When oxidized polyunsaturated oils, such as corn oil or
        linoleic acid, are added to food, they appear in the blood lipids, where they accelerate the formation of
        cholesterol deposits in arteries (Staprans, et al., 1994, 1996). Stress accelerates the oxidation of the
        polyunsaturated fatty acids in the body, so people who consume unsaturated vegetable oils and fish will have
        some oxidized cholesterol in their tissues. The constant turnover of cholesterol in the tissues tends to lower
        the proportion of the toxic oxidized degradation products of cholesterol, but in hypothyroidism, the use of
        cholesterol is slowed, allowing the toxic forms to accumulate. Many antioxidant nutrients act like a thyroid
        supplement did in the 1934 rabbit experiments, preventing atherosclerosis even when extra toxic cholesterol is
        given to the animals. People who eat seafood get much more selenium in their diet than people who eat nothing
        from the sea, and selenium is one of the extremely protective nutrients that prevent atherosclerosis in animal
        experiments with excess cholesterol. It is well established that several antioxidant nutrients are protective
        factors in heart disease. The medical establishment has expended a great amount of money and time in the last 60
        years fighting the use of vitamin E or selenium for treating or preventing heart disease, though many physicians
        now take vitamin E themselves. But people who study free radical chemistry recognize that polyunsaturated fats
        are highly susceptible to oxidation, and that saturated fats tend to slow their degradation, acting to some
        extent as antioxidants. Several experiments and observations have shown that cholesterol itself can protect
        against damaging oxidation of polyunsaturated fats, protecting DNA and other vital components of the cell. A
        consistent program to prevent the oxidation of cholesterol would have to include all of the vitamins and
        minerals that are involved in antioxidant defense, avoidance of nutrients that exacerbate the destructive
        oxidations, and an effort to normalize the hormones and other factors, such as carbon dioxide, that have
        protective effects against free radical oxidation. A low level of cholesterol might increase susceptibility to
        the oxidants. The steroids in general, especially those produced in large amounts, progesterone and DHEA, are
        important parts of the antioxidant defenses. Cholesterol, either that produced internally by the cell, or taken
        in from the blood stream, is the precursor for all the steroids in the body. Several of the major steroid
        hormones are antiinflammatory, and cholesterol itself is antiinflammatory. (Mikko, et al., 2002; Kreines, et
        al., 1990). Cholesterol also protects against radiation damage, and many forms of toxin (saponins, cobra venom,
        chloroform--W.G. MacCallum, <em>
            A Text-book of</em>
        <em>Pathology,</em> 1937, Saunders Co.; many more recent studies show that it protects blood cells against
        hemolysis--breakdown of red blood cells--caused by heat and other harmful agents; e.g., Dumas, et al., 2002,
        Velardi, et al., 1991). Cholesterol, vitamin E, progesterone, and vitamin D are considered to be "structural
        antioxidants," that prevent oxidation partly by stabilizing molecular structures. One of the basic functions of
        cholesterol seems to be the stabilization of mitochondria, preventing their destruction by stress. Serious
        stress lowers ATP, magnesium, and carbon dioxide. When ATP and intracellular magnesium are decreased,
        cholesterol synthesis increases. During stress, free fatty acids are released from the tissues, and circulating
        in the bloodstream they are highly susceptible to oxidation. They contribute to the formation of the age
        pigment, lipofuscin, which is an oxygen-wasting substance that's found in the atheroma plaques in the damaged
        blood vessels. Iron and calcium accumulation adds to the tissue damage. The hemolysis which is promoted by
        polyunsaturated fats and an imbalance of antioxidants and oxidants, releases iron and heme into the blood
        stream. The incidence of atherosclerosis is increased when the body iron stores are high (Kiechl, et al., 1997),
        probably because of its role in lipid peroxidation and lipofuscin formation. Especially when the lining of the
        blood vessel is too permeable, because of the influence of polyunsaturated fats, prostaglandins, estrogen, etc.,
        the heme and iron will enter the endothelial cells, where the iron will catalyze the formation of free radicals,
        and the heme will be broken down by the enzyme heme oxygenase, into biliverdin, iron, and carbon monoxide, which
        can contribute to the oxidative stress of the cells. Carbon monoxide makes the blood vessel lining more
        permeable, allowing fats and fibrinogen to enter the cells (Allen, et al., 1988). Although cholesterol is
        protective against oxidative and cytolytic damage, the chronic free radical exposure will oxidize it. During the
        low cholesterol turnover of hypothyroidism, the oxidized variants of cholesterol will accumulate, so cholesterol
        loses its protective functions. When the metabolic pathways of the steroid hormones were being worked out, an
        experimenter perfused an isolated ovary with blood. When the amount of cholesterol in the blood pumped into the
        ovary was increased, the amount of progesterone in the blood leaving the ovary increased proportionately. In the
        healthy organism, cholesterol is constantly being synthesized, and constantly converted into steroid hormones,
        and, in the liver, into the bile salts that are secreted to emulsify fats in the intestine. Thyroid hormone and
        vitamin A are used in the process of converting cholesterol into pregnenolone, the immediate precursor of
        progesterone and DHEA. Anything that interfered with these processes would be disastrous for the organism. The
        supply of cholesterol, thyroid and vitamin A must always be adequate for the production of steroid hormones and
        bile salts. When stress suppresses thyroid activity, increased cholesterol probably compensates to some extent
        by permitting more progesterone to be synthesized. In very young people, the metabolic rate is very high, and
        the rapid conversion of cholesterol into pregnenolone, DHEA, and progesterone usually keeps the level of
        cholesterol in the blood low. In the 1930s, a rise in the concentration of cholesterol was considered to be one
        of the most reliable ways to diagnose hypothyroidism (<em>1936 Yearbook of Neurology, Psychiatry, and
            Endocrinology,</em> E.L. Sevringhaus, editor, Chicago, p. 533). With aging, the metabolic rate declines, and
        the increase of cholesterol with aging is probably a spontaneous regulatory process, supporting the synthesis of
        the protective steroids, especially the neurosteroids in the brain and retina. Many people refer to the
        structural importance of cholesterol for "membranes," and often imply that the membranes are just at the surface
        of the cell (the plasma membrane). But in fact cholesterol is found in the nucleus in the chromosomes, bound to
        DNA and in the nuclear matrix that governs the activation of genes, and in the mitotic spindle, which regulates
        separation of the chromosomes during cell division<strong>:</strong> without sufficient cholesterol, cells
        divide irregularly, producing aneuploid daughter cells (i.e., they have an abnormal number of chromosomes).
        Aneuploidy is now coming to be recognized as an essential feature of cancer cells. A significant amount of
        cholesterol was recently discovered to bind to hemoglobin, suggesting that it will be found in association with
        many other types of protein, when it occurs to anyone to look for it. Osmotic regulation, which is closely
        involved in cell division and other functions, appears to require cholesterol synthesis. Around 1985, a big
        study in Hungary showed that lowering cholesterol with drugs caused a huge increase in the cancer death rate.
        Hundreds of publications appeared in the U.S. saying that wasn't possible, because low cholesterol is good, the
        lower the better. The extreme increase in cancer mortality in the Hungarian study was probably the result of the
        drug that was commonly used at that time to lower cholesterol, but the pattern of mortality in that study was
        approximately the same pattern seen in any group with very low cholesterol. In the last 20 years, there have
        been many studies showing that lowering cholesterol increases mortality, especially from cancer and suicide, and
        that people with naturally low cholesterol are more likely to die from cancer, suicide, trauma, and infections
        than people with normal or higher than average cholesterol. The increased mortality from accidents and suicide
        when cholesterol is lowered is reminiscent of the problems seen in progesterone deficiency, and it's very likely
        that a deficiency of the neurosteroids accounts for it. A deficiency of progesterone and other neurosteroids
        (the steroids synthesized by the nerves themselves) causes depression of mood and impaired learning ability,
        among other neurological changes. As was the case with cancer, the pharmaceutical industry continues to deny
        that their anticholesterol drugs cause suicide, depression, and dementia, but there is a large amount of
        evidence from human as well as animal studies showing that mood and intelligence are depressed by lowering
        cholesterol. Simply injecting cholesterol into animals can improve their learning ability. In the Framingham
        heart study of 1894 people extending over a period of about 20 years, people with cholesterol naturally in the
        "desirable" range, below 200 mg.%, scored lower on "verbal fluency, attention/concentration, abstract reasoning,
        and a composite score measuring multiple cognitive domains" than those with higher cholesterol (Elias, et al.,
        2005).

        The next step in studies of this sort should be to see how the combination of extra thyroid with adequate
        cholesterol influences longevity. The rising cholesterol that commonly occurs with aging is probably only
        partial compensation for declining thyroid function, and by optimizing all of the protective factors, radical
        changes in the aging process may be possible. In the roundworm C. elegans, which is now a very popular animal
        for testing aging theories, because its genes and cells have been thoroughly "mapped," it was recently found
        that adding a gene that simply allows it to synthesize cholesterol, rather than depending on food for its
        sterols, increased its life span by as much as 131% (Lee, et al., 2005). That would be like increasing the human
        lifespan to about 175 years. These worms are also more resistant than normal to radiation and heat stress. The
        cells of the thymus are extremely sensitive to radiation and other stressors, and their enrichment with
        cholesterol inhibits lipid peroxidation, DNA degradation, and death in response to radiation (Posokhov, et al.,
        1992). Many high altitude regions of the world have high levels of background radiation, from minerals as well
        as cosmic rays, so it has been dogmatically believed that mortality from cancer and heart disease would increase
        with altitude, but the reverse is true. Because oxygen at lower pressure displaces less carbon dioxide from the
        blood, the body is able to retain more carbon dioxide at high altitude. Carbon dioxide protects against free
        radicals, and also helps to deliver oxygen to tissues, to maintain efficient energy production, and to prevent
        cellular stress. One study found 18 times higher incidence of hypertension in low altitude populations than in
        high altitude people (Fiori, et al., 2000). For many years, these principles have been applied in treating
        atherosclerosis and other degenerative diseases, in high altitude health resorts. Even a short period of hypoxic
        treatment can improve the body's ability to eliminate atherogenic lipid peroxides, possibly by improving the
        stress-resistant functions of the liver (Meerson, et al., 1988; Aleshin, et al., 1993; Kitaev, et al., 1999). I
        think editors of medical journals generally see themselves as the purveyors of enlightenment, i.e., as the
        pushers of the stylish and prestigious doctrines. (Selectivity of evidence to serve the received doctrine is the
        commonest form of scientific dishonesty.) But because their mental framework is culturally narrow, they
        sometimes publish things which later could turn out to be embarrassing (if inconsistency could embarrass such
        types). The recent discovery that the size of the LDL particle is a predominant factor in the development of
        atherosclerosis is one of those things that the editors and medical professors should find embarrassing. Smaller
        lipoprotein particles have a greater surface area exposed to the oxidative factors in the serum, and so are more
        rapidly degraded into toxic substances. People with larger LDL particles are remarkably resistant to heart
        disease, and the drug companies are looking for a way to turn their lipoproteins into products. But the
        conditions that govern the size of the LDL particles are physically and chemically reasonable, and are causing
        confusion among the doctinaire. There have been several studies in India showing that consumption of butter and
        ghee is associated with a low incidence of heart disease; for example, according to one study, people in the
        north eat 19 times more fat (mostly butter and ghee) than in the south, yet the incidence of heart disease is
        seven times higher in the south. A study in Sweden found that the fatty acids in milk products are associated
        with larger LDL particles (Sjogren, et al., 2004). In a 35 day study, when butter (20% of the calories) was
        compared to various kinds of margarine (with more trans fatty acids) in a similar quantity, the LDL particles
        were bigger on the butter diet (Mauger, et al., 2003). But in a study of the habitual diet of 414 people, large
        LDL particles were found to be correlated with increased intake of protein, animal fat, and trans fatty acids
        (Kim and Campos, 2003). In a study of the effect of dietary cholesterol on the atherogenicity of the blood
        lipids, 52 people were given either an egg diet (with 640 mg. of extra cholesterol per day) or a placebo diet
        for 30 days. Those whose LDL increased the most on the high cholesterol diet had the largest LDL particle size
        (Herron, et al., 2004). They concluded that "these data indicate that the consumption of a high-cholesterol diet
        does not negatively influence the atherogenicity of the LDL particle." A similar study in Mexico found that
        "Intake of 2 eggs/d results in the maintenance of LDL:HDL and in the generation of a less atherogenic LDL in
        this population of Mexican children" (Ballesteros, et al., 2004). The estrogen industry tried to get into the
        heart disease business several times over the last half century, and they are still trying, but the issue of
        estrogen's harmful effects on LDL particle size is getting some attention. Estrogen clearly decreases the size
        of the LDL particles (Campos, et al., 1997). The LDL particles also get smaller at menopause, and in polycystic
        ovary syndrome, and in preeclamptic pregnancies, all of which involve a low ratio of progesterone to estrogen.
        But there are still journals publishing claims that estrogen will protect against heart disease, by reducing the
        atherogenic response in increasingly mysterious ways. Occasionally, people have argued not only that estrogen is
        the factor that protects women against heart attacks, but that androgens predispose men to heart disease. One of
        their arguments has been that androgens lower HDL, the "good" form of cholesterol. However, there are many
        studies that show that testosterone and DHEA (Arad, et al., 1989) are protective against atherosclerosis. The
        LDL particle size is increased by androgens, and postprandial triglyceridemia is decreased (Hislop, et al.,
        2001). The studies in the 1930s that showed the protective effects of thyroid hormone against atherosclerosis
        and heart disease have sometimes been interpreted to mean that the thyroid is protective <strong><em>because</em
            ></strong>
        it lowers the cholesterol, but since cholesterol is protective, rather than harmful, something else explains the
        protective effect. Ever since the time of Virchow, who called atherosclerosis <strong><em>arteritis
                deformans,</em></strong>
        the inflammatory nature of the problem has been clear to those who aren't crazed by the anticholesterol cult. We
        are all subject to a variable degree of inflammatory stimulation from the endotoxin absorbed from the intestine,
        but a healthy liver normally prevents it from reaching the general circulation, and produces a variety of
        protective factors. The HDL lipoprotein is one of these, which protects against inflammation by binding
        bacterial endotoxins that have reached the bloodstream. (Things that increase absorption of endotoxin--exercise,
        estrogen, ethanol--cause HDL to rise.) Chylomicrons and VLDL also absorb, bind, and help to eliminate
        endotoxins. All sorts of stress and malnutrition increase the tendency of endotoxin to leak into the
        bloodstream. Thyroid hormone, by increasing the turnover of cholesterol and its conversion into the protective
        steroids, is a major factor in keeping the inflammatory processes under control. In hypothyroidism, the
        pituitary secretes more TSH to activate the thyroid gland, but TSH itself has a variety of pro-inflammatory
        actions. The C-reactive protein (CRP), which is recognized as a factor contributing to atherosclerosis, is
        increased in association with TSH. CRP activates mast cells, which are found in the atheroma plaques, to produce
        a variety of pro-inflammatory substances, including histamine. The belief that cells are controlled by a plasma
        membrane, and that cholesterol's main function is to participate in that membrane, has led to a culture that
        treats cholesterol physiology with little curiosity. A different perspective on the cell starts with a
        recognition of the lipophilic nature of the structural proteins (not "membrane proteins," but things like
        cytoskeleton-cytoplasmic ground substance, spindle, centrosome-centrioles, nuclear matrix, etc.), with which
        lipids interact. Modifying an extremely complex system, the living substance, cholesterol participates in
        complexity, and must be investigated with subtlety. I suspect that the physiological meaning of cholesterol has
        to do with movement, stability, differentiation, memory, and sensitivity of the parts of the cells, that is,
        with everything physiological. The functions of cholesterol parallel the functions of other sterols in plants
        and other types of organism. Its functions have been refined and extended with the development of other
        steroids, such as progesterone, as biological requirements have evolved, but cholesterol is still at the center
        of this system. To deliberately interfere with its synthesis, as contemporary medicine does, reveals a terrible
        arrogance. Many participants in the cholesterol-lowering cult believe that they have succeeded in hijacking our
        science culture, but when the patents on another generation of their drugs have expired, the cult could begin to
        fade away.

            Protective CO2 and aging
        </h1>

        <p></p>
        <p>
            The therapeutic effects of increasing carbon dioxide are being more widely recognized in recent years. Even
            Jane Brody, the NY Times writer on health topics, has favorably mentioned the use of the Buteyko method for
            asthma, and the idea of "permissive hypercapnia" during mechanical ventilation, to prevent lung damage from
            excess oxygen, has been discussed in medical journals. But still very few biologists recognize its role as a
            fundamental, universal protective factor. I think it will be helpful to consider some of the ways carbon
            dioxide might be controlling situations that otherwise are poorly understood.
        </p>

        <p>
            The brain has a high rate of oxidative metabolism, and so it forms a very large proportion of the carbon
            dioxide produced by an organism. It also governs, to a great extent, the metabolism of other tissues,
            including their consumption of oxygen and production of carbon dioxide or lactic acid. Within a particular
            species, the rate of oxygen consumption increases in proportion to brain size, rather than body weight.
            Between very different species, the role of the brain in metabolism is even more obvious, since the resting
            metabolic rate corresponds to the size of the brain. For example, a cat's brain is about the size of a
            crocodile's, and their oxygen consumption at rest is similar, despite their tremendous difference in body
            size.
        </p>
        <p>
            Stress has to be understood as a process that develops in time, and the brain (especially the neocortex and
            the frontal lobes) organizes the adaptive and developmental processes in both the spatial and temporal
            dimensions. The meaning of a situation influences the way the organism responds. For example, the stress of
            being restrained for a long time can cause major gastrointestinal bleeding and ulcerization, but if the
            animal has the opportunity to bite something during the stress (signifying its ability to fight back, and
            the possibility of escape) it can avoid the stress ulcers.
        </p>
        <p>
            The patterning of the nervous activity throughout the body governs the local ability to produce carbon
            dioxide. When the cortex of the brain is damaged or removed, an animal becomes rigid, so the cortex is
            considered to have a "tonic inhibitory action" on the body. But when the nerves are removed from a muscle
            (for example, by disease or accident), the muscle goes into a state of constant activity, and its ability to
            oxidize glucose and produce carbon dioxide is reduced, while its oxidation of fatty acids persists,
            increasing the production of toxic oxidative fragments of the fatty acids, which contributes to the muscle's
            atrophy.
        </p>
        <p>
            The organism's intentions, expectations, or plans, are represented in the nervous system as a greater
            readiness for action, and in the organs and tissues controlled by the nerves, as an increase or decrease of
            oxidative efficiency, analogous to the differences between innervated and denervated muscles. This pattern
            in the nervous system has been called "the acceptor of action," because it is continually being compared
            with the actual situation, and being refined as the situation is evaluated. The state of the organism, under
            the influence of a particular acceptor of action, is called a "functional system," including all the
            components of the organism that participate most directly in realizing the intended adaptive action.
        </p>
        <p>
            The actions of nerves can be considered anabolic, because during a stressful situation in which the
            catabolic hormones of adaption, e.g., cortisol, increase, the tissues of the functional system are
            protected, and while idle tissues may undergo autophagy or other form of involution, the needs of the active
            tissues are supplied with nutrients from their breakdown, allowing them to change and, when necessary, grow
            in size or complexity.
        </p>

        <p>
            The brain's role in protecting against injury by stress, when it sees a course of action, has a parallel in
            the differences between concentric (positive, muscle shortening) and eccentric (negative, lengthening under
            tension) exercise, and also with the differences between innervated and denervated muscles. In eccentric
            exercise and denervation, less oxygen is used and less carbon dioxide is produced, while lactic acid
            increases, displacing carbon dioxide, and more fat is oxidized. Prolonged stress similarly decreases carbon
            dioxide and increases lactate, while increasing the use of fat.
        </p>
        <p>
            Darkness is stressful and catabolic. For example, in aging people, the morning urine contains nearly all of
            the calcium lost during the 24 hour period, and mitochondria are especially sensitive to the destructive
            effects of darkness. Sleep reduces the destructive catabolic effects of darkness. During the
            rapid-eye-movement (dreaming) phase of sleep, breathing is inhibited, and the level of carbon dioxide in the
            tissues accumulates. In restful sleep, the oxygen tension is frequently low enough, and the carbon dioxide
            tension high enough, to trigger the multiplication of stem cells and mitochondria.
        </p>
        <p>
            Dreams represent the "acceptor of action" operating independently of the sensory information that it
            normally interacts with. During dreams, the brain (using a system called the Ascending Reticular Activating
            System) disconnects itself from the sensory systems. I think this is the nervous equivalent of
            concentric/positive muscle activity, in the sense that the brain is in control of its actions. The active,
            dreaming phase of sleep occurs more frequently in the later part of the night, as morning approaches. This
            is the more stressful part of the night, with cortisol and some other stress hormones reaching a peak at
            dawn, so it would be reasonable for the brain's defensive processes to be most active at that time. The
            dreaming process in the brain is associated with deep muscle relaxation, which is probably associated with
            the trophic (restorative) actions of the nerves.

            In ancient China the Taoists were concerned with longevity, and according to Joseph Needham (<em>Science and
                Civilization in China</em>) their methods included the use of herbs, minerals, and steroids extracted
            from the urine of children. Some of those who claimed extreme longevity practiced controlled breathing and
            tai chi (involving imagery, movement, and breating), typically in the early morning hours, when stress
            reduction is most important. As far as I know, there are no studies of carbon dioxide levels in
            practitioners of tai chi, but the sensation of warmth they typically report suggests that it involves
            hypoventilation.

            In the 1960s, a Russian researcher examined hospital records of measurements of newborn babies, and found
            that for several decades the size of their heads had been increasing. He suggested that it might be the
            result of increasing atmospheric carbon dioxide.
        </p>

            The experiences and nutrition of a pregnant animal are known to affect the expression of genes in the
            offspring, affecting such things as allergies, metabolic rate, brain size, and intelligence. Miles Storfer
            (1999) has reviewed the evidence for epigenetic environmental control of brain size and intelligence. The
            main mechanisms of epigenetic effects or "imprinting" are now known to involve methylation and acetylation
            of the chromosomes (DNA and histones).
        </p>
        <p>
            Certain kinds of behavior, as well as nutrition and other environmental factors, increase the production and
            retention of carbon dioxide. The normal intrauterine level of carbon dioxide is high, and it can be
            increased or decreased by changes in the mother's physiology. The effects of carbon dioxide on many
            biological processes involving methylation and acetylation of the genetic material suggest that the
            concentration of carbon dioxide during gestation might regulate the degree to which parental imprinting will
            persist in the developing fetus. There is some evidence of increased demethylation associated with the low
            level of oxygen in the uterus (Wellman, et al., 2008). A high metabolic rate and production of carbon
            dioxide would increase the adaptability of the new organism, by decreasing the limiting genetic imprints.
        </p>
        <p>
            A quick reduction of carbon dioxide caused by hyperventilation can provoke an epileptic seizure, and can
            increase muscle spasms and vascular leakiness, and (by releasing serotonin and histamine) contribute to
            inflammation and clotting disorders. On a slightly longer time scale, a reduction of carbon dioxide can
            increase the production of lactic acid, which is a promoter of inflammation and fibrosis. A prolonged
            decrease in carbon dioxide can increase the susceptibility of proteins to glycation (the addition of
            aldehydes, from polyunsaturated fat peroxidation or methylglyoxal from lactate metabolism, to amino groups),
            and a similar process is likely to contribute to the methylation of histones, a process that increases with
            aging. Histones regulate genetic activity.
        </p>
        <p>
            With aging, DNA methylation is increased (Bork, et al., 2009). <strong>I suggest that methylation stabilizes
                and protects cells when growth and regeneration aren't possible (and that it's likely to increase when
                CO2 isn't available).
            </strong>

            Hibernation (Morin and Storey, 2009) and sporulation (Ruiz-Herrera, 1994; Clancy, et al., 2002) appear to
            use methylation protectively.
        </p>
        <p>
            Parental stress, prenatal stress, early life stress, and even stress in adulthood contribute to "imprinting
            of the genes," partly through methylation of DNA and the histones.
        </p>
        <p>
            Methionine and choline are the main dietary sources of methyl donors. Restriction of methionine has many
            protective effects, including increased average (42%) and maximum (44%) longevity in rats (Richie, et al.,
            1994). Restriction of methyl donors causes demethylation of DNA (Epner, 2001). <strong> </strong>
            The age accelerating effect of methionine might be related to disturbing the methylation balance,
            inappropriately suppressing cellular activity. Besides its effect on the methyl pool, methionine inhibits
            thyroid function and damages mitochondria.
        </p>
        <p>
            The local concentration of carbon dioxide in specific tissues and organs can be adjusted by nervous and
            hormonal activation or inhibition of the carbonic anhydrase enzymes, that accelerate the oonversion of CO2
            to carbonic acid, H2CO3. The activity of carbonic anhydrase can determine the density and strength of the
            skeleton, the excitability of nerves, the accumulation of water, and can regulate the structure and function
            of the tissues and organs.
        </p>
        <p>
            Ordinarily, carbon dioxide and bicarbonate are thought of only in relation to the regulation of pH, and only
            in a very general way. Because of the importance of keeping the pH of the blood within a narrow range,
            carbon dioxide is commonly thought of as a toxin, because an excess can cause unconsciousness and acidosis.
            But increasing carbon dioxide doesn't necessarily cause acidosis, and acidosis caused by carbon dioxide
            isn't as harmful as lactic acidosis.
        </p>

        <p>
            Frogs and toads, being amphibians, are especially dependent on water, and in deserts or areas with a dry
            season they can survive a prolonged dry period by burrowing into mud or sand. Since they may be buried 10 or
            11 inches below the surface, they are rarely found, and so haven't been extensively studied. In species that
            live in the California desert, they have been known to survive 5 years of burial without rainfall, despite a
            moderately warm average temperature of their surroundings. One of their known adaptations is to produce a
            high level of urea, allowing them to osmotically absorb and retain water. (Very old people sometimes have
            extremely high urea and osmotic tension.)
        </p>
        <p>
            Some laboratory studies show that as a toad burrows into mud, the amount of carbon dioxide in its tissues
            increases. Their skin normally functions like a lung, exchanging oxygen for carbon dioxide. If the toad's
            nostrils are at the surface of the mud, as dormancy begins its breathing will gradually slow, increasing the
            carbon dioxide even more. Despite the increasing carbon dioxide, the pH is kept stable by an increase of
            bicarbonate (Boutilier, et al., 1979). A similar increase of bicarbonate has been observed in hibernating
            hamsters and doormice.
        </p>
        <p>
            Thinking about the long dormancy of frogs reminded me of a newspaper story I read in the 1950s. Workers
            breaking up an old concrete structure found a dormant toad enclosed in the concrete, and it revived soon
            after being released. The concrete had been poured decades earlier.
        </p>
        <p>
            Although systematic study of frogs or toads during their natural buried estivation has been very limited,
            there have been many reports of accidental discoveries that suggest that the dormant state might be extended
            indefinitely if conditions are favorable. Carbon dioxide has antioxidant effects, and many other stabilizing
            actions, including protection against hypoxia and the excitatory effects of intracellular calcium and
            inflammation (Baev, et al., 1978, 1995; Bari, et al., 1996; Brzecka, 2007; Kogan, et al., 1994; Malyshev, et
            al., 1995).
        </p>
        <p>
            When mitochondria are "uncoupled," they produce more carbon dioxide than normal, and the mitochondria
            produce fewer free radicals. Animals with uncoupled mitochondria live longer than animals with the ordinary,
            more efficient mitochondria, that produce more reactive oxidative fragments. One effect of the high rate of
            oxidation of the uncoupled mitochondria is that they can eliminate polyunsatured fatty acids that might
            otherwise be integrated into tissue structures, or function as inappropriate regulatory signals.
        </p>

            Birds have a higher metabolic rate than mammals of the same size, and live longer. Their tissues contain
            fewer of the highly unsaturated fatty acids. Queen bees, which live many times longer than worker bees, have
            mainly monounsaturated fats in their tissues, while the tissues of the short-lived worker bees, receiving a
            different diet, within a couple of weeks of hatching will contain highly unsaturated fats.

            Bats have a very high metabolic rate, and an extremely long lifespan for an animal of their size. While most
            animals of their small size live only a few years, many bats live a few decades. Bat caves usually have
            slightly more carbon dioxide than the outside atmosphere, but they usually contain a large amount of
            ammonia, and bats maintain a high serum level of carbon dioxide, which protects them from the otherwise
            toxic effects of the ammonia.
        </p>
        <p>
            The naked mole rat, another small animal with an extremely long lifespan (in captivity they have lived up to
            30 years, 9 or 10 times longer than mice of the same size) has a low basal metabolic rate, but I think
            measurements made in laboratories might not represent their metabolic rate in their natural habitat. They
            live in burrows that are kept closed, so the percentage of oxygen is lower than in the outside air, and the
            percentage of carbon dioxide ranges from 0.2% to 5% (atmospheric CO2 is about 0.038). The temperature and
            humidity in their burrows can be extremely high, and to be very meaningful their metabolic rate would have
            to be measured when their body temperature is raised by the heat in the burrow.
        </p>
        <p>
            When they have been studied in Europe and the US, there has been no investigation of the effect of altitude
            on their metabolism, and these animals are native to the high plains of Kenya and Ethiopia, where the low
            atmospheric pressure would be likely to increase the level of carbon dioxide in their tissues. Consequently,
            I doubt that the longevity seen in laboratory situations accurately reflects the longevity of the animals in
            their normal habitat.
        </p>
        <p>
            Besides living in a closed space with a high carbon dioxide content, mole rats have another similarity to
            bees. In each colony, there is only one female that reproduces, the queen, and, like a queen bee, she is the
            largest individual in the colony. In beehives, the workers carefully regulate the carbon dioxide
            concentration, which varies from about 0.2% to 6%, similar to that of the mole rat colony. A high carbon
            dioxide content activates the ovaries of a queen bee, increasing her fertility.
        </p>
        <p>
            Since queen bees and mole rats live in the dark, I think their high carbon dioxide compensates for the lack
            of light. (Both light and CO2 help to maintain oxidative metabolism and inhibit lactic acid formation.) Mole
            rats are believed to sleep very little. During the night, normal people tolerate more CO2, and so breathe
            less, especially near morning, with increased active dreaming sleep.

            A mole rat has never been known to develop cancer. Their serum C-reactive protein is extremely low,
            indicating that they are resistant to inflammation. In humans and other animals that are susceptible to
            cancer, one of the genes that is likely to be silenced by stress, aging, and methylation is p53, a
            tumor-suppressor gene.
        </p>
        <p>
            If the intrauterine experience, with low oxygen and high carbon dioxide, serves to "reprogram" cells to
            remove the accumulated effects of age and stress, and so to maximize the developmental potential of the new
            organism, a life that's lived with nearly those levels of oxygen and carbon dioxide might be able to avoid
            the progressive silencing of genes and loss of function that cause aging and degenerative diseases.
        </p>
        <p>
            Several diseases and syndromes are now thought to involve abnormal methylation of genes. Prader-Willi
            sydrome, Angelman's syndrome, and various "autistic spectrum disorders," as well as post-traumatic stress
            disorder and several kinds of cancer seem to involve excess methylation.
        </p>
        <p>
            Moderate methionine restriction (for example, using gelatin regularly in the diet) might be practical, but
            if increased carbon dioxide can activate the demethylase enzymes in a controlled way, it might be a useful
            treatment for the degenerative diseases and for aging itself.
        </p>
        <p>
            The low carbon dioxide production of hypothyroidism (e.g., Lee and Levine, 1999), and the respiratory
            alkalosis of estrogen excess, are often overlooked. An adequate supply of calcium, and sometimes
            supplementation of salt and baking soda, can increase the tissue content of CO2.

            of recurrent nocturnal hypoxia in obstructive sleep apnea (OSA). The potential role of elevated carbon
            dioxide (CO2) in improving brain oxygenation in the patients with severe OSA syndrome is discussed. CO2
            increases oxygen uptake by its influence on the regulation of alveolar ventilation and ventilation-perfusion
            matching, facilitates oxygen delivery to the tissues by changing the affinity of oxygen to hemoglobin, and
            increases cerebral blood flow by effects on arterial blood pressure and on cerebral vessels. Recent clinical
            studies show improved brain oxygenation when hypoxia is combined with hypercapnia. Anti-inflammatory and
            protective against organ injury properties of CO2 may also have therapeutic importance. These biological
            effects of hypercapnia may improve brain oxygenation under hypoxic conditions. This may be especially
            important in patients with severe OSA syndrome.

            Lee HT, Levine M. <a href="mailto:Tl128@columbia.edu" target="_blank">Tl128@columbia.edu</a> PURPOSE:
            Patients with severe hypothyroidism present unique challenges to anesthesiologists and demonstrate much
            increased perioperative risks. Overall, they display increased sensitivity to anesthetics, higher incidence
            of perioperative cardiovascular morbidity, increased risks for postoperative ventilatory failure and other
            physiological derangements. The previously described physiological basis for the increased incidence of
            postoperative ventilatory failure in hypothyroid patients includes decreased central and peripheral
            ventilatory responses to hypercarbia and hypoxia, muscle weakness, depressed central respiratory drive, and
            resultant alveolar hypoventilation. These ventilatory failures are associated most frequently with severe
            hypoxia and carbon dioxide (CO2) retention. The purpose of this clinical report is to discuss an interesting
            and unique anesthetic presentation of a patient with severe hypothyroidism. CLINICAL FEATURES: We describe
            an unique presentation of ventilatory failure in a 58 yr old man with severe hypothyroidism. He had
            exceedingly low perioperative respiratory rate (3-4 bpm) and minute ventilation volume, and at the same time
            developed primary acute respiratory alkalosis and associated hypocarbia (P(ET)CO2 approximately 320-22
            mmHg). CONCLUSION: Our patient's ventilatory failure was based on unacceptably low minute ventilation and
            respiratory rate that was unable to sustain adequate oxygenation. His profoundly lowered basal metabolic
            rate and decreased CO2 production, resulting probably from severe hypothyroidism, may have resulted in
            development of acute respiratory alkalosis in spite of concurrently diminished minute ventilation.

                diseases.
            </strong>Sananbenesi F, Fischer A. The orchestrated expression of genes is essential for the development and
            survival of every organism. In addition to the role of transcription factors, the availability of genes for
            transcription is controlled by a series of proteins that regulate epigenetic chromatin remodeling. The two
            most studied epigenetic phenomena are DNA methylation and histone-tail modifications. Although a large body
            of literature implicates the deregulation of histone acetylation and DNA methylation with the pathogenesis
            of cancer, recently epigenetic mechanisms have also gained much attention in the neuroscientific community.
            In fact, a new field of research is rapidly emerging and there is now accumulating evidence that the
            molecular machinery that regulates histone acetylation and DNA methylation is intimately involved in
            synaptic plasticity and is essential for learning and memory. Importantly, dysfunction of epigenetic gene
            expression in the brain might be involved in neurodegenerative and psychiatric diseases. In particular, it
            was found that inhibition of histone deacetylases attenuates synaptic and neuronal loss in animal models for
            various neurodegenerative diseases and improves cognitive function. In this article, we will summarize
            recent data in the novel field of neuroepigenetics and discuss the question why epigenetic strategies are
            suitable therapeutic approaches for the treatment of brain diseases.

            </strong>
            Wu H, Sun YE. Neurogenesis in the adult mammalian brain involves activity-dependent expression of genes
            critical for the proliferation of progenitors and for neuronal maturation. A recent study suggests that the
            stress response gene Gadd45b (growth arrest and DNA-damage-inducible protein 45 beta) can be transiently
            induced by neuronal activity and may promote adult neurogenesis through dynamic DNA demethylation of

            "Hypercapnia reduced NMDA-evoked responses in a concentration-dependent manner, with 7.5 and 15 % CO2 in the
            breathing mixture reducing the depolarization amplitude to 74 % and 64 % of that of the initial stimuli,
            respectively. Application of 50 mM NH4+ progressively reduced dialysate pH, and a further acidification was
            observed when NH4+ was discontinued. Perfusion of NMDA after NH4+ application evoked smaller depolarizations
            (56 % of the corresponding control, 5 min after NH4+ removal), and this effect persisted for over 1 h."
            "Together, these results demonstrate that extracellular acidosis, such as that associated with excessive

            <span style="color: #222222"><span style="font-family: Helvetica"><span>More than 100 years ago the idea of
                        a morphogenetic field was proposed by A.G. Gurwitsch, as a way to explain the orderly movements
                        of cells in embryos and growing tissues, and to understand the principles that cause cells to
                        change appropriately when their location in the organism changes. For 30 years, the concept
                        guided research in embryology, but also led to important discoveries in the biology of cancer,
                        aging, wound repair, and other important areas. But by the late 1940s, a more abstract approach
                        to biology, based on the gene doctrine of Mendel and Weismann, took charge of academic and
                        governmental biological research. This ideology at first said that organisms are determined by
                        unchanging units of inheritance, "genes," and later when genes were found to be susceptible to
                        mutation, the changes were said to be always random. The Central Dogma of the ideology was that
                        any meaningful, adaptive changes that occur in an organism can't influence the genes. For many
                        years, adaptive changes were said to be nothing but changes in the size or function of existing
                        cells, because the cells of the major organs of the body were supposed to be created before
                        birth, or in infancy.&nbsp;</span></span></span>

                        hardening, dehydrating, and slicing parts of organisms. Biochemists studied the chemistry of
                        life mainly by grinding cells or tissues, and extracting water soluble materials to study the
                        actions of enzymes on various materials. These unrealistic artifacts filled the textbooks and
                        the minds of generations of biologists and physicians. The culture of molecular biology used
                        these artifacts to create theories of embryology and physiology, and holistic ideas such as the
                        developmental field were disregarded.</span></span></span>

                        progressive loss of muscle mass, sarcopenia (or myopenia). The structure of aging tissue
                        changes, with collagen tending to fill the spaces left by the disappearing cells. It's also

                        replace any that were lost. But when conditions are less perfect, injuries are imperfectly
                        repaired, usually with highly collagenous scar tissue bridging the area that was destroyed.
                        During this imperfect repair, there is inflammation, which apparently exists to the extent that
                        the substances needed for regeneration are lacking. For example, when oxygen is lacking, lactic

                        by a deficiency of sodium, is one of the factors that can increase blood pressure; if the
                        tissues's glycogen stores are depleted, the adrenalin will mobilize free fatty acids from the
                        tissues, which tends to inhibit energy production from glucose, and to increase leakiness. After
                        I had read Tom Brewer's work on preventing or curing preeclampsia with added salt, I realized
                        that the premenstrual syndrome involved some of the features of preeclampsia (edema, insomnia,
                        cramps, hypertension, salt craving), so I suggested to a friend that she might try salting her
                        food to taste, instead of trying to restrict salt to "prevent edema." She immediately noticed
                        that it prevented her monthly edema problem. For several years, all the women who tried it had
                        similarly good results, and often mentioned that their sleep improved. I mentioned this to
                        several people with sleep problems, and regardless of age, their sleep improved when they ate as
                        much salt as they wanted. Around that time, several studies had shown that salt restriction
                        increases adrenalin, and one study showed that most old people on a low sodium diet suffered
                        from insomnia, and had unusually high adrenalin. When they ate a normal amount of salt, their
                        adrenalin was normalized, and they slept better.</span></span></span>

                        liberates free fatty acids from the tissues, so when the tissues contain large amounts of the

        <h1>
            Epilepsy and Progesterone
        </h1>
        <p>
            The length of the life-span, and of the period of youth or immaturity, is closely associated with the size
            of the brain, and the brain has a very high rate of metabolism. When something interferes with this very
            high metabolic rate, the consequences may be instantanteous,* or developmental, or chronic and degenerative,
            or even transgenerational. The issue of epilepsy centers on questions of brain metabolism, and so it has all
            of those dimensions.
        </p>
        <p>
            As I discuss the mechanisms known to predispose a person to epilepsy, I will emphasize the centrality of
            oxidative energy production, and show how "stroke," "stress," "hyperactivity," "dementia," and other brain
            syndromes are related to "epilepsy." (Similar processes are being studied in the heart and other tissues;
            eventually, we might have a general language that will make it easier to understand the parallels in the
            various kinds of "seizure" in any organ.)
        </p>
        <p>
            As an old term, "epilepsy" has aquired a burden of pseudoscientific ideas, covering old superstitions with
            an overlay of new superstitions. [Hereditary epilepsy has been discussed in countless textbooks and medical
            journals, but I think a much better case could be made for the inheritance of a tendency to offer stupid
            genetic explanations.] "Hereditary epilepsy" and "idiopathic epilepsy" are seriously pathogenic terms;
            "brain scar" sometimes has a factual basis, but most often the term is an evasion of understanding.
        </p>

        <p>
            As long as we realize that the essential meaning of the word is "something that grabs you," "epilepsy" is a
            convenient way to refer to a cluster of convulsive states, fainting spells, night-terrors and nightmares,
            and strange sensations.
        </p>
        <p>
            Seizures can be caused by lack of glucose, lack of oxygen, vitamin B6 deficiency, and magnesium deficiency.
            They are more likely to occur during the night, during puberty, premenstrually, during pregnancy, during the
            first year of life, and can be triggered by hyperventilation, running, strong emotions, or unusual sensory
            stimulation. Water retention and low sodium increase susceptibility to seizures. When I was in high school,
            our dog found and ate a pint of bacon grease, and shortly afterward had a convulsive seizure. I knew of
            veterinarians who treated seizures in dogs with a vermifuge, so it seemed obvious that a metabolic
            disturbance, especially if combined with intestinal irritation, could cause fits.
        </p>
        <p>
            It was undoubtedly such observations that led some physicians to advocate removal of the colon as treatment
            for epilepsy. Pregnancy and the menstrual cycle have been recognized as having something to do with
            seizures, but when seizures occurred only during pregnancy, they were classified as nonepileptic, and when
            they had a clear premenstrual occurrence, they were likely to be classified as "hysterical fits," to be
            treated with punishment.
        </p>
        <p>
            It has been observed that all "recognized" anti-seizure drugs are teratogenic, and women who are taking such
            drugs are told that pregnancy might kill them if they stop the drug, but that their babies will have a
            greatly increased risk of birth defects if they take the drugs during pregnancy. This is why a better
            understanding of epilepsy is very important. Old therapies are mainly important for the insight they can
            give into the nature of the physiological problem. Some of the well established clinical-laboratory
            observations (F. Mora, and C. S. Babel, for example) give strong hints as to the physiological problem, for
            example, low albumin, high prealbumin, low magnesium and high calcium all suggest hypothyroidism. (Problems
            with the bowel, liver, and sex hormones are highly associated with hypothyroidism, both as causes and as
            effects.) Water retention was so clearly involved in seizures that increased water intake was used as a
            diagnostic procedure. (R. Grinker) Unfortunately, animal experiments showed that water intoxication
            increased susceptibility to seizures even in normal individuals. Low sodium content in the body fluids also
            predisposed to seizures, so that someone with hyponatremia (low blood sodium) would be more susceptible to
            induction of a seizure by excessive water intake. (Excessive water uptake is still recognized as a factor in
            seizures, but now it is seen as part of a complex process, involving energy, hormones, and transmitter
            substances. E.g., Kempski; Chan.)
        </p>
        <p>
            Hypothyroid people tend to lose sodium easily, and unopposed estrogen increases water retention, without an
            equivalent sodium retention, so low thyroid, high estrogen people have two of the conditions (edema and
            hyponatremia) known to predispose to seizures. Another outstanding feature of seizures of various sorts is
            that they are most likely to occur at night, especially in the early pre-dawn hours. Low blood sugar and
            high adrenalin predominate during those hours. Hypoglycemia, in itself, like oxygen deprivation, is enough
            to cause convulsions.
        </p>
        <p>
            Progesterone and thyroid promote normal energy production, and their deficiency causes a tendency toward
            hypoglycemia, edema and instability of nerves.
        </p>
        <p>
            Twenty years ago, a woman who was considered demented visited me. From the age of 21, she had been
            increasingly disabled by premenstrual migraines. When she was 35 she was a school teacher, and during the
            summer a neurologist told her that dilantin would help her headaches, because "migraine is similar to
            epilepsy." Although she told the neurologist that the drug made her "too stupid to teach school," he offered
            her no alternatives, and didn't mention that sudden withdrawal from the drug could trigger a seizure. When
            classes started she discontinued the dilantin and had a seizure. The neurologist said the seizure proved
            that migraines were a form of epilepsy. At the age of 52, she spent about 20 hours a day in bed, and
            couldn't go outside by herself, because she would get lost. After using a little progesterone for a few
            days, she stopped having seizures, discontinued her drugs, and was able to work. When she returned to
            graduate school, she got straight As, and earned her masters' degree in gerontology. But she had lost 17
            years because the drug industry had covered up the role of the hormones in epilepsy, migraine, and the
            perimenstrual syndrome.
        </p>

        <p>
            The most popular anticonvulsant drugs are both neurotoxic and teratogenic, that is, they damage the
            patient's brain, and greatly increase the incidence of birth defects. The Nazis justified their horrible
            medical experiments as "science," but the effects of epilepsy medicine in the last half century have been
            similar in effect, grander in scale, and without any scientific justification.
        </p>
        <p>
            Besides the specific promotional efforts of the drug industry and their branch of government, there is a
            broader situation that makes their work easier. It is a culture of goony ideas, that ultimately emanates
            from the academic elite, which (since Descartes, and before) places "thought" above evidence. In biology,
            "genes" and "membranes" are confused ideas that are used to justify actions that aren't based on evidence.
            For the Nazis, "cultural degeneracy" was a medical-biological-political category based on that style of
            thinking. In the United States, "genes" for epilepsy, hyperactivity, language development, IQ, eclampsia,
            etc., are "found" at Harvard/MIT/Stan- ford/Yale/Univ. of California, etc., by an elite whose wits have been
            dulled by environmental deprivation, that is, by a lack of criticism.
        </p>
        <p>
            By manipulating the diet and environment, animals can be made more or less seizure-prone, and it happens
            that the changes that affect the brain affect all other organs, in ways that are now fairly well understood.
            Examining the cellular events associated with a seizure is useful for therapy and prevention of seizures,
            but the same methods are helpful for many other conditions. It is now clearly established that stress can
            cause brain damage, as well as other diseases. Now that our public health establishment has eliminated
            smoking from public places, maybe they can find a way to reduce stress and disease by removing morons from
            positions of power.
        </p>
        <p>
            Excitotoxicity, in its simplest sense, is the harmful cellular effect (death or injury) caused by an
            excitatory transmitter such as glutamate or aspartate acting on a cell whose energetic reserves aren't
            adequate to sustain the level of activity provoked by the transmitter. Once an excitotoxic state exists, the
            consequences of cell exhaustion can increase the likelihood that the condition will spread to other cells,
            since any excitation can trigger a complex of other excitatory processes. As calcium enters cells, potassium
            leaves, and enzymes are activated, producing free fatty acids (linoleic and arachidonic, for example) and
            prostaglandins, which activate other processes, including lipid peroxidation and free radical production.
            Protein kinase C (promoted by unsaturated fats and estrogen) facilitates the release of excitatory amino
            acids. (See J. W. Phillis and M. H. O'Regan, "Mechanisms of glutamate and aspartate release in the ischemic
            rat cerebral cortex," Br. Res. 730(1-2), 150-164, 1996.) Estrogen supports acetylcholine release, which
            leads to increased extracellular potassium and excitatory amino acids. (See R. B. Gibbs, et al., "Effects of
            estrogen on potassium-stimulated acetylcholine release in the hippocampus and overlying cortex of adult
            rats," Br. Res. 749(1), 143-146, 1997.)
        </p>

        <p>
            Estrogen also stimulates the production of free radicals. Calcium, free radicals, and unsaturated free fatty
            acids impair energy production, decreasing the ability to regulate potassium and calcium. The increased
            estrogen associated with seizures is associated with reduced serum calcium (Jacono and Robertson, 1987).
            Feedback self-stimulation of free radicals, free fatty acids, and prostaglandins create a bias toward
            increased excitation.
        </p>
        <p>
            Ammonia is produced by stimulated nerves, and normally its elimination helps to eliminate and control the
            excitotoxic amino acids, glutamate and aspartate. The production of urea consumes aspartic acid, converting
            it to fumaric acid, but this requires carbon dioxide, produced by normal mitochondrial function. A
            deficiency of carbon dioxide would reduce the delivery of oxygen to the brain by constricting blood vessels
            and changing hemoglobin's affinity for oxygen (limiting carbon dioxide production), and the failure to
            consume aspartate (in urea synthesis) and glutamate (as alpha-ketoglutarate) and aspartate (as oxaloacetate)
            in the Krebs cycle, means that as energy becomes deficient, excitation tends to be promoted. This helps to
            explain the fact that seizures can be induced by hypoxia. (Balloonists and mountain climbers at extremely
            high elevations have mentioned suffering from severe insomnia. The mechanisms of excitotoxicity are probably
            involved in other forms of insomnia, too.) Antioxidants help to control seizures, by reducing the excitatory
            contribution of free radicals and lipid peroxidation. Since excitation can promote the toxic forms of
            oxidation, many surprising substances turn out to have an "antioxidant" function. Magnesium, sodium
            (balancing calcium and potassium), thyroid and progesterone (increasing energy production), and in some
            situations, carbon dioxide. Aspirin, by inhibiting prostaglandin synthesis (and maybe other mechanisms)
            often lowers free radical production. Adenosine seems to have a variety of antioxidant functions, and one
            mechanism seems to be its function as an antiexcitatory transmitter. One of estrogen's excitant actions on
            the brain probably involves its antagonism to adenosine (Phillis and O'Regan, 1988).
        </p>
        <p>
            Albumin, besides maintaining blood volume and preventing edema, serves to protect respiration, by binding
            free fatty acids. Estrogen blocks the liver's ability to produce albumin, and increases the level of
            circulating free fatty acids. Free fatty acids cause brain edema. This is probably another aspect of
            estrogen's contribution to seizure susceptibility. Magnesium sulfate has been used for generations in India
            to treat eclampsia and "toxemia" of pregnancy, and its effectiveness is gradually coming to be recognized in
            the U.S. Increasingly, magnesium deficiency is recognized as a factor that increases susceptibility to
            seizures. (Valenzuela and Benardo, 1995; Slandley, et al., 1995). Hypothyroidism reduces the ability of
            cells to retain magnesium. Thyroid does many things to protect against seizures. It keeps estrogen and
            adrenal hormones low, and increases production of progesterone and pregnenolone. It facilitates retention of
            magnesium and of sodium, and prevents edema in a variety of ways.

            Progesterone, because of its normal anesthetic function (which prevents the pain of childbirth when its
            level is adequate), directly quiets nerves, and in this way suppresses many of the excitotoxic processes. It
            has direct effects on mitochondria, promoting energy production, and it facilitates thyroid hormone
            functions in various ways. It promotes the elimination of estrogen from tissues, and is a "diuretic" in
            several benign ways, that are compatible with maintenance of blood volume. It antagonizes the
            mineralocorticoids and the glucocorticoids, both of which promote seizures. (Roberts and Keith, 1995.) The
            combination of hypoglycemia with elevation of cortisone probably accounts for the nocturnal incidence of
            seizures.

            If progesterone's antiepileptic effectiveness were not enough (and it is very effective even in irrational
            pharmaceutical formulations), the fact that it reduces birth defects, and promotes brain development and
            nerve repair should assure its general use in women with a history of seizures, until it is established that
            they are no longer "epileptic." Although thyroid, progesterone, and a high quality protein diet will
            generally correct the epilepsy problem, it is important to mention that the involvement of unsaturated fats
            and free radicals in seizure physiology implies that we should minimize our consumption of the unsaturated
            fats. Even years after eliminating them from the diet, their release from tissue storage can prolong the
            problem, and during that time the use of vitamin E is likely to reduce the intensity and frequency of
            seizures. Coconut oil lowers the requirement for vitamin E, and reduces the toxicity of the unsaturated fats
            (see Cleland, et al.), favoring effective respiration and improving thyroid and progesterone production.
            Endotoxin formed in the bowel can block respiration and cause hormone imbalances contributing to instability
            of the nerves, so it is helpful to optimize bowel flora, for example with a carrot salad; a dressing of
            vinegar, coconut oil and olive oil, carried into the intestine by the carrot fiber, suppresses bacterial
            growth while stimulating healing of the wall of the intestine. The carrot salad improves the ratio of
            progesterone to estrogen and cortisol, and so is as appropriate for epilepsy as for premenstrual syndrome,
            insomnia, or arthritis.

            When the brain loses its oxygen supply, consciousness is lost immediately, before there is much decrease in
            the ATP concentration. This has led to the proposal of interesting "electronic" ideas of consciousness, but
            there is another way of viewing this. While ATP constitutes a kind of reservoir of cellular energy, the flow
            of carbon dioxide through the brain cell is almost the mirror image of the flow of oxygen. Oxygen scarcity
            leads directly to carbon dioxide scarcity. The "sensitive state," consciousness, might require the presence
            of carbon dioxide as well as ATP, to sustain a cooperative, semi-stable, state of the cytoplasmic proteins.
            The ability of ordinary light to trigger a conformation change in the hemoglobin-carbon monoxide-carbon
            dioxide system shows how sensitive a system with only a few elements can be. At the other extreme from
            consciousness, there is the evidence that carbon dioxide is essential for even the growing/living state of
            protozoa, algae, and bacteria.(O. Rahn, 1941.)

            these circumstances, bacteria cannot multiply."

            <p>
                A review of the use of estrogens reported in J.A.M.A. (only up to 1987) found nearly 200 different
                "indications" for its use. (Palmlund, 1996.) Using the conservative language of that journal, such use
                could be said to constitute wildly irresponsible "empirical" medical practice. More appropriate language
                could be used.
            </p>

            <p>
                Pollution of the environment and food supply by estrogenic chemicals is getting increased attention.
                Early in the study of estrogens, it was noticed that soot, containing polycyclic aromatic hydrocarbons,
                was both estrogenic and carcinogenic. Since then, it has been found that phenolics and chlorinated
                hydrocarbons are significantly estrogenic, and that many estrogenic herbicides, pesticides, and
                industrial by-products persist in the environment, causing infertility, deformed reproductive organs,
                tumors, and other biological defects, including immunodeficiency. In the Columbia River, a recent study
                found that about 25% of the otters and muskrats were anatomically deformed.
            </p>

            <p>
                Estrogenic pollution kills birds, panthers, alligators, old men, young women, fish, seals, babies, and
                ecosystems. Some of these chemicals are sprayed on forests by the US Department of Agriculture, where
                they enter lakes, underwater aquifers, rivers, and oceans. Private businesses spray them on farms and
                orchards, or put them into the air as smoke or vapors, or dump them directly into rivers. Homeowners put
                them on their lawns and gardens.
            </p>

            <p>
                Natural estrogens, from human urine, enter the rivers from sewage. Many tons of synthetic and
                pharmaceutical estrogens, administered to menopausal women in quantities much larger than their bodies
                ever produced metabolically, are being added to the rivers.
            </p>

            <p>
                In the same way that weak estrogens in the environment may become hundreds of times more estrogenic by
                synergistic interactions (J. A. McLachlan, et al., <em>Science,</em> June 7, 1996), combinations of
                natural, medical, dietary, and environmental estrogens are almost certain to have unexpected results.
                The concept of a "protective estrogen" is very similar to the idea of "protective mutagens" or
                "protective carcinogens," though <em>in the case of estrogens, their promoters don't even know what the
                    normal, natural functions of estrogen are.
                </em>
            </p>

            <p>
                In November, 1995, an international conference was held to study the problem of "Environmental
                endocrine-disrupting chemicals," and to devise strategies for increasing public awareness of the
                seriousness of the problem. Their "Statement from the work session" says "New evidence is especially
                worrisome because it underscores the exquisite sensitivity of the developing nervous system to chemical
                perturbations that result in functional abnormalities." "This work session was convened because of the
                growing concern that failure to confront the problem could have major economic and societal
                implications." <strong>"We are certain of the following: Endocrine-disrupting chemicals can undermine
                    neurological and behavioral development and subsequent potential of individuals...."</strong>
                "Because the endocrine system is sensitive to perturbation, it is a likely target for disturbance."
                "Man-made endocrine-disrupting chemicals range across all continents and oceans. They are found in
                native populations from the Arctic to the tropics, and, because of their persistence in the body, can be
                passed from generation to generation." <strong>"...many endocrine-disrupting contaminants, even if less
                    potent than the natural products, are present in living tissue at concentrations millions of times
                    higher than the natural hormones."</strong> "The developing brain exhibits specific and often narrow
                windows during which exposure to endocrine disruptors can produce permanent changes in its structure and
                function."
            </p>

            <p>
                In spite of this increased exposure to estrogens, there is a new wave of advertising of estrogenic
                substances, based on the idea that weak estrogens will provide protection against strong estrogens. The
                environmental background of estrogenic pollution already provides a continuous estrogenic exposure. In
                the 1940s, Alexander Lipshuts demonstrated that a continuous, weak estrogenic stimulus was immensely
                effective in producing, first fibromas, then cancer, in one organ after another, and the effect was not
                limited to the reproductive system. How is it possible that the idea of "protection" from a weak
                estrogen seems convincing to so many? Isn't this the same process that we saw when the nuclear industry
                promoted Luckey's doctrine of "radiation hormesis," literally the claim that "a little radiation is
                positively good for us"?
            </p>

            <p>
                DES (diethyl stilbestrol) is one of the most notorious estrogens, because studies in humans revealed
                that its use during pregnancy not only caused cancer, miscarriages, blood clots, etc., in the women who
                used it, but also caused cancer, infertility, and deformities in their children, and even in their
                grandchildren. (But those transgenerational effects are not unique to it.)
            </p>

            <p>
                Besides the absurd use of DES to prevent miscarriages, around 1950 it was also used to treat
                vulvovaginitis in little girls, for menstrual irregularity at puberty, to treat sterility, dysfunctional
                bleeding, endometriosis, amenorrhea, oligomenorrhea, dysmenorrhea, migraine headaches, nausea and
                vomiting, and painful breast engorgement or severe bleeding after childbirth.
            </p>

            <p>
                DES is a "weak" estrogen, in the sense that it doesn't compete with natural estrogens for the "estrogen
                receptors." (Estriol binds more strongly to receptors than DES does: "Cytosolic and nuclear estrogen
                receptors in the genital tract of the rhesus monkey," J. Steroid Bioch. 8(2), 151-155, 1977.) Pills
                formerly contained from 5 to 250 mg. of DES. The 1984 <em>PDR</em> lists doses for hypogonadism and
                ovarian failure as 0.2 to 0.5 mg. daily. In general, dosage of estrogens decreased by a factor of 100
                after the 1960s.
            </p>

            <p>
                An aggressively stupid editorial by Alvin H. Follingstad, from the Jan. 2, 1978, issue of JAMA, pages
                29-30, "Estriol, the forgotten estrogen?" is being circulated to promote the use of estriol, or the
                phytoestrogens. It argues that women who secrete larger amounts of estriol are resistant to cancer.
            </p>

            <p>By some tests, estriol is a "weak estrogen," by others it is a powerful estrogen.</p>

            <p>
                When estriol was placed in the uterus of a rabbit, only 1.25 mcg. was sufficient to prevent implantation
                and destroy the blastocyst. (Dmowski, et al., 1977.) Since the effect was local, the body weight of the
                animal doesn't make much difference, when thinking about the probable effect of a similar local
                contentration of the hormone on human tissues. The anti-progestational activity of estriol and estradiol
                are approximately the same. (Tamotsu and Pincus, 1958.)
            </p>

            <p>
                When 5 mg. of estriol was given to women intravaginally, this very large dose suppressed LH within 2
                hours, and suppressed FSH in 5 hours. Given orally, 8 mg. had similar effects on LH and FSH after 30
                days, and also had an estrogenic effect on the vaginal epithelium.. These quick systemic effects of a
                "weak estrogen" are essentially those of a strong estrogen, except for the size of the dose. (Schiff, et
                al., 1978.)
            </p>

            <p>When administered subcutaneously, estriol induced abortions and stillbirths (Velardo, et al.)</p>

            <p>
                Another indication of the strength of an estrogen is its ability to cause the uterus to enlarge. Estriol
                is slightly weaker, in terms of milligrams required to cause a certain rate of uterine enlargement, than
                estradiol. (Clark, et al., 1979.) But isn't the important question whether or not the weak estrogen
                imitates all of the effects of estradiol, including carcinogenesis and blood clotting, in addition to
                any special harmful effects it might have?
            </p>

            <p>
                When added to long-term culture of human breast cancer cells, estriol stimulated their growth, and
                overcame the antiestrogenic effects of tamoxifen, even at concentrations hundreds of times lower than
                that of tamoxifen. "The data do not support an antiestrogenic role for estriol in human breast cancer."
                (Lippman, et al., 1977.)
            </p>

            <p>
                Studies of the urinary output of estriol/estradiol in women with or without breast cancer do not
                reliably show the claimed association between low estriol/estradiol and cancer, and the stimulating
                effect of estriol on the growth of cancer cells suggests that any alteration of the estrogen ratio is
                likely to be a <em>consequence</em> of the disease, rather than a cause. The conversion of estradiol to
                other estrogens occurs mainly in the liver, in the non-pregnant woman, as does the further metabolism of
                the estrogens into glucuronides and sulfates. The hormonal conditions leading to and associated with
                breast cancer all affect the liver and its metabolic systems. The hydroxylating enzymes are also
                affected by toxins. Hypothyroidism (low T3), low progesterone, pregnenolone, DHEA, etiocholanolone, and
                high prolactin, growth hormone, and cortisol are associated with the chronic high estrogen and breast
                cancer physiologies, and modify the liver's regulatory ability.

                The decreased output of hormones when the fetal-placental system is dying is a natural consequence,
                since the placenta produces hormones, and during pregnancy converts estradiol to estriol. Since
                estradiol in excess kills the fetus, its conversion by the placenta to estriol is in accord with the
                evidence showing that estriol is the more quickly excreted form. (G. S. Rao, 1973.) The conversion of
                16-hydroxy androstenedione and 16-hydroxy-DHEA into estriol by the placenta (Vega Ramos, 1973) would
                also cause fetal exhaustion or death to result in lower estriol production. But a recent observation
                that a surge of estriol production precedes the onset of labor, and that its premature occurrence can
                identify women at risk of premature delivery (McGregor, et al., 1995) suggests that the estriol surge
                might reflect the mother's increased production of adrenal androgens during stress. (This would be
                analogous to the situation in the polycystic ovary syndrome, in which excessive estradiol drives the
                adrenals to produce androgens.)

            <p>
                Estetrol, which has one more hydroxyl group than estriol, is a "more sensitive and reliable indicator of
                fetal morbidity than estriol during toxemic pregnancies," because it starts to decrease earlier, or
                decreases more, than estriol. (Kundu, et al., 1978.) This seems to make it even clearer that the decline
                of estriol is a consequence, not a cause, of fetal sickness or death.

                A 1994 publication (B. Zumoff, "Hormonal profiles in women with breast cancer," <em>Obstet. Gynecol.
                    Clin. North. Am. (U.S.) 21(4),</em> 751-772) reported that there are four hormonal features in women
                with breast cancer<strong>:</strong> diminished androgen production, luteal inadequacy, increased
                16-hydroxylation of estradiol, and increased prolactin. The 16-hydroxylation converts estradiol into
                estriol.

                A new technique for radiographically locating a hormone-dependent breast cancer is based on the fact
                that estriol-sulfate is a major metabolite of estradiol. The technique showed the tumor to have about a
                six times higher concentration of estriol-sulfate than liver or muscle. (N. Shimura, et al., "Specific
                imaging of hormone-dependent mammary carcinoma in nude mice with [131I]-anti-estriol 3-sulfate
                antibody," <em>Nucl. Med. Biol. (England) 22(5),</em> 547-553, 1995.)
            </p>

            <p>
                Another association of elevated conversion of estradiol to estriol with disease was found to occur in
                men who had a myocardial infarction, compared to controls who hadn't. (W. S. Bauld, et al., 1957.)

                The estrogens in clover have been known for several decades to have a contraceptive action in sheep, and
                other phytoestrogens are known to cause deformities in the genitals, feminization of men, and anatomical
                changes in the brain as well as functional masculinization of the female brain. (Register, et al., 1995;
                Levy, et al, 1995; Clarkson, et al., 1995; Gavaler, et al., 1995.) The effects of the phytoestrogens are
                very complex, because they modify the sensitivity of cells to natural estrogens, and also modify the
                metabolism of estrogens, with the result that the effects on a given tissue can be either pro-estrogenic
                and anti-estrogenic. For example, the flavonoids, naringenin, quercetin and kaempherol (kaempherol is an
                antioxidant, a phytoestrogen, and a mutagen) modify the metabolism of estradiol, causing increased
                bioavailability of both estrone and estradiol. (W. Schubert, et al., "Inhibition of 17-beta-estradiol
                metabolism by grapefruit juice in ovariectomized women," <em>Maturitas (Ireland) 30(2-3),</em> 155-163,
                1994.)

            <p>
                Why do plants make phytoestrogens? There is some information indicating that these compounds evolved to
                regulate the plants' interactions with other organisms--to attract bacteria, or to repel insects, for
                example, rather than just as pigment-forming materials. (Baker, 1995.) The fact that some of them bind
                to our "estrogen receptors" is probably misleading, because of their many other effects, including
                inhibiting enzyme functions involved in the regulation of steroids and prostaglandins. Their
                biochemistry in animals is much more complicated than that of natural estrogens, which is itself so
                complicated that we can only guess what the consequences might be when we change the concentration and
                the ratio of substances in that complex system. (See quotation from Velardo, et al., page 6)
            </p>

            <p>
                These "natural" effects in sheep were forerunners of the observed estrogenic effects in wild animals,
                caused by pollutants. Twenty-five years ago I reviewed many of the issues of estrogen's toxicity, and
                the ubiquity of estrogenic substances, and since then have regularly spoken about it, but I haven't
                concentrated much attention on the phytoestrogens, because we can usually just choose foods that are
                relatively free of them. They are so often associated with other food toxins--antithyroid factors,
                inhibitors of digestive enzymes, immunosuppressants, etc.--that the avoidance of certain foods is
                desirable. Recently an advocate of soybeans said "if they inhibit the thyroid, why isn't there an
                epidemic of hypothyroidism in Asia?" I happened to hear this right after seeing newspaper articles about
                China's problem with 100,000,000 cretins<strong>;</strong> yes, Asia has endemic hypothyroidism, and
                beans are widely associated with hypothyroidism.

            <p>
                When I first heard about clover-induced miscarriages in sheep, I began reading about the subject,
                because it was relevant to the work I was doing at that time on reproductive aging. Sheep which are
                adapted to living at high altitude, where all animals have reduced fertility, have an adaptive type of
                hemoglobin, with a greater affinity for oxygen. Fetal hemoglobin, in animals at sea-level, has a great
                affinity for oxygen, making it possible for the fetus to get enough oxygen, despite its insulation from
                the mother's direct blood supply. The high-altitude-tolerant sheep have hemoglobin which is able to
                deliver sufficient oxygen to the uterus to meet the needs of the embryo/fetus, even during relative
                oxygen-deprivation. These sheep are able to sustain pregnancy while grazing on clover. It seemed evident
                that estrogen and high altitude had something in common, namely, oxygen deprivation, and it also seemed
                evident that these sheep provided the explanation for estrogen's abortifacient effects.
            </p>

            <p>
                Estrogen's effects, ranging from shock to cancer, all seem to relate to an interference with the use of
                oxygen. Different estrogens have different affinities for various tissues, and a given substance is
                likely to have effects other than estrogenicity, and the presence of other substances will modify the
                way a tissue responds, but the stressful shift away from oxidative production of energy is the factor
                that all estrogens have in common. Otherwise, how could suffocation and x-irradiation have estrogenic
                effects?
            </p>

            <p>
                Pharmaceutical misrepresentations regarding the estrogens rank, in terms of human consequences, with the
                radiation damage from fall-out from bomb tests and reactor-leaks, with industrial pollution, with
                degradation of the food supply--with genocide, in fact.

                Advertising gets a bad name when it can't be distinguished from mass murder. At a certain point, we
                can't afford to waste our time making subtle distinctions between ignorance and malevolence. If we begin
                pointing out the lethal consequences of "stupid" or quasi-stupid commer- cial/governmental policies, the
                offenders will have the burden of proving that their actions are the result of irresponsible ignorance,
                rather than criminal duplicity. From the tobacco senators to the chemical/pharmaceutical/food/energy
                industries and their agents in the governmental agencies, those who do great harm must be held
                responsible.

                The idea of corporate welfare, in which public funds are given in massive subsidies to rich
                corporations, is now generally recognized. Next, we have to increase our consciousness of corporate
                responsibility, and that ordinary criminal law, especially RICO, can be directly applied to
                corporations. It remains to be seen whether a government can be made to stop giving public funds to
                corporations, and instead, to begin enforcing the law against them--and against those in the agencies
                who participated in their crimes.

                In the U.S., the death penalty is sometimes reserved for "aggravated homicide." If those who kill
                hundreds of thousands for the sake of billions of dollars in profits are not committing aggravated
                homicide, then it must be that no law written in the English language can be objectively interpreted,
                and the legal system is an Alice in Wonderland convenience for the corporate state.

                interrelationships when tested on uterine growth had <strong>simple additive interactions when tested on
                    the vaginal smears." "...it seems reasonable to postulate that a given hormone combination may evoke
                    differing levels of response in different target organs, and particularly, that increase of one
                    component may increase response at one site while decreasing it at another. Many steroids...are
                    present in the mammalian circulation during various phases of the sex cycle and are known to modify
                    the effects of any given estrogen. This hormonal multiplicity apparently constitutes an
                    estrogen-buffering system and supports the hypothesis that sexual responses depend '...upon a rather
                    precise hormonal homeostasis.'"</strong>

                    itself is a potent estrogen, contrary to the usual conception of its being just a metabolite of the
                    more potent estrone and estradiol.</strong> Although ordinarily less effective than estrone and
                estradiol in promoting vaginal cornification, estriol, under optimum conditions, approaches their
                effectiveness for this purpose. Estriol is more potent than estrone or estradiol in causing
                establishment and opening of the vaginal orifice, in promoting imbibition of uterine fluid, in
                increasing lactic dehydrogenase activity in the uterus, and in stimulating mitotic activity in the
                epidermis of the mouse ear. The activity of estriol is of the same order of magnitude as that of estrone
                and estradiol in other estrogenic actions, such as to promote uterine growth at low concentrations
                (although less effective at high doses), to increase beta-glucuronidase and reduced diphosphopyridine
                nucleotide oxidase activity in the uterus, to reduce motility of the uterus in vivo, and to stimulate
                ovarian growth, body weight, phagocytosis of carbon by reticuloendothelial cells, ciliary movements of
                the buccopharyngeal mucose of the frog, and new bone formation. The fibromatogenic activity of estriol
                in the guinea pig is much less than that of estrone or estradiol. Recent experiments suggest and partly
                verify the hypothesis that estriol stimulates the cervix, vagina and vulva more effectively than estrone
                or estradiol, whereas the latter are much more effective on the corpus uteri."

                    receptor-organ response is not accomplished by the independent action of one hormone alone. It
                    appears more likely that such response is the physiological expression of the sum total of the

                estriol on the birth rate of these rats was more dramatic." "...when estriol was used before mating, it
                reduced the litter size to 66 per cent of the controls." "However, when the same dose was employed from
                the day of mating and daily thereafter beyond the time of usual implantation, 6 days later, a reduction
                of live births to 33 per cent of the controls was produced. In this experiment the medication was
                withheld until after ovulation had presumably occurred. The presence of placental scars and an increased
                incidence of abortions and stillbirths argues against the possibility that the fertile ova have been
                'locked' by the estrogen in the tubes." "...the incidence of placental scars, abortions, and stillbirths

            Estrogen and Osteoporosis
        </h1>

        The government declared victory in the war on cancer, though the age-specific death rate from cancer keeps
        increasing. In the equally well publicized effort to prevent disability and death from osteoporosis, no one is
        declaring victory, because the only trend in its incidence that has been reported is an increase. The
        estrogen-promoting culture tells us that this is because of the aging of the population, but the age corrected
        numbers still show a great increase--for example, in Finland between 1970 and 1995, the number of women (for a
        given population of women older than 60) breaking their forearm because of osteoporosis more than doubled
        (Palvanen, et al., 1998). That this happened during a time when the use of estrogen had become much more common
        doesn't present a good argument for the protective effects of estrogen treatment. (And during this period there
        was a large increase in the consumption of estrogenic soy products.) Recently our local newspaper had a story at
        the bottom of the front page reporting that lean women who used estrogen and synthetic progestins had an 80%
        higher rate of breast cancer. Several days later, across the top of the front page, there was a rebuttal
        article, quoting some doctors including a "world class expert on hormone replacement therapy" and a woman who
        has taken Premarin for forty years and urges everyone to take it. The "protection against osteoporosis" and
        against heart disease, they said, must be weighed against a trifle such as the 80% increase in cancer. It
        appeared that the newspaper was apologizing for reporting a fact that could make millions of women nervous. (Jan
        26, Register-Guard). Medical magazines, like the mass media, don't like to miss any opportunity to inform the
        public about the importance of using estrogen to prevent osteoporosis. Their attention to the bone-protective
        effect of progesterone has been noticeably less than their mad campaign to sell estrogen, despite the evidence
        that progesterone can promote bone rebuilding, rather than just slowing its loss. Although I have spoken about
        progesterone and osteoporosis frequently in the last 25 years, I have only occasionally considered what estrogen
        does to bones; generally, I described estrogen as a stress-promoting and age-promoting hormone. In the 1970s,
        pointing out progesterone's protective antagonism to excessive amounts of other hormones, and that the catabolic
        glucocorticoids tend to increase with aging, I began referring to progesterone as the "anticatabolic" hormone
        that should be used to prevent stress-induced atrophy of skin, bones, brain, etc. A former editor of Yearbook of
        Endocrinology had reviewed a series of studies showing that excess prolactin can cause osteoporosis. Then, he
        presented a group of studies showing how estrogen promotes the secretion of prolactin, and can cause
        hyperprolactinemia. In that review, he wryly wondered how something that increases something that causes
        osteoporosis could prevent osteoporosis. Women have a higher incidence of osteoporosis than men do. Young women
        have thinner more delicate bones than young men. The women who break bones in old age are generally the women
        who had the thinnest bones in youth. Menstrual irregularities, and luteal defects, that involve relatively high
        estrogen and low progesterone, increase bone loss. Fatter women are less likely to break bones than thinner
        women. Insulin, which causes the formation of fat, also stimulates bone growth. Estrogen however, increases the
        level of free fatty acids in the blood, indicating that it antagonizes insulin (insulin decreases the level of
        free fatty acids), and the fatty acids themselves strongly oppose the effects of insulin. Estrogen dominance is
        widely thought to predispose women to diabetes. Between the ages of 20 and 40, there is a very considerable
        increase in the blood level of estrogen in women. However, bone loss begins around the age of 23, and progesses
        through the years when estrogen levels are rising. Osteoarthritis, which involves degeneration of the bones
        around joints, is strongly associated with high levels of estrogen, and can be produced in animals with estrogen
        treatment. Thirty years ago, when people were already claiming that estrogen would prevent or cure osteoporosis,
        endocrinologists pointed out that there was no x-ray evidence to support the claim. Estrogen can cause a
        positive calcium balance, the retention of more calcium than is excreted, and the estrogen promoters argued that
        this showed it was being stored in the bones, but the endocrine physiologists showed that estrogen causes the
        retention of calcium by soft tissues. There are many reasons for not wanting calcium to accumulate in the soft
        tissues; this occurs normally in aging and stress. Then, it was discovered that, although estrogen doesn't
        improve the activity of the cells that build bone, it can reduce the activity of the cells that remove bone, the
        osteoclasts. The osteoclast is a type of phagocytic cell, and is considered to be a macrophage, the type of cell
        that can be found in any organ, which can eat any sort of particle, and which secretes substances (cytokines,
        hormone-like proteins) that modify the functions of other cells. When estrogen was found to impair the activity
        of this kind of cell, there wasn't much known about macrophage cytokines. With the clear evidence that estrogen
        inhibits the osteoclasts without activating the bone-building osteoblasts, estrogen was said to "prevent bone
        loss," and from that point on we never heard again about estrogen promoting a positive calcium balance. Calcium
        retention by soft tissues has come to be an accepted marker of tissue aging, tissue damage, excitotoxicity, and
        degeneration. Positive calcium balance had been the essence of the argument for using estrogen to prevent
        osteoporosis: "Women are like chickens, estrogen makes them store calcium in their bones." But if everyone now
        recognizes that calcium isn't being stored in bones, it's better for the estrogen industry if we forget about
        the clearly established positive calcium balance produced by estrogen. The toxic effects of excessive
        intracellular calcium (decreased respiration and increased excitation) are opposed by magnesium. Both thyroid
        and progesterone improve magnesium retention. Estrogen dominance is often associated with magnesium deficiency,
        which can be an important factor in osteoporosis (Abraham and Grewal, 1990; Muneyyirci-Delale, et al., 1999). As
        part of the campaign to get women to use estrogen, an x-ray (bone density) test was devised which can supposedly
        measure changes in the mineral content of bone. However, it happens that fat and water interfere with the
        measurements. Estrogen changes the fat and water content of tissues. By chance, the distortions produced by fat
        and water happen to be such that estrogen could appear to be increasing the density of a bone, when it is really
        just altering the soft tissues. Ultrasound measurements can provide very accurate measurements of bone density,
        without the fat and water artifacts that can produce misleading results in the x-ray procedure, and don't expose
        the patient to radiation, but the ultrasound method is seldom used. In recent years, there has been quite a lot
        of research into the effects of the macrophage cytokines. Immune therapy for cancer was considered quackery when
        Lawrence Burton identified some substances in blood serum that could cause massive tumors in rodents to
        disappear in just a few hours. One of the serum factors was called Tumor Necrosis Factor, TNF. An official
        committee was formed to evaluate his work, but it reported that there was nothing to it. A member of the
        committee later became known as "the authority" on tumor necrosis factor, which was thought to have great
        potential as an anticancer drug. However, used by itself, TNF killed only a few cancers, but it damaged every
        organ of the body, usually causing the tissues to waste away. Other names, lymphotoxin and cachectin, reflected
        its toxic actions on healthy tissues. Aging involves many changes that tend to increase the inflammatory
        reaction, and generally the level of TNF increases with aging. Although cancer, heart failure, AIDS, and extreme
        hormone deficiency (from loss of the pituitary or thyroid gland, for example) can cause cachexia of an extreme
        and rapid sort, ordinary aging is itself a type of cachexia. Progeria, or premature aging, is a kind of wasting
        disease that causes a child's tissues (including bones) to atrophy, and to change in many of the ways that would
        normally occur in extreme old age. Recent studies have found that both men and women lose minerals from their
        bones at the rate of about 1% per year. Although men have lower estrogen in youth than women do, their bones are
        much heavier. During aging, as their bones get thinner, men's estrogen levels keep rising. Besides having weaker
        bones, old people have weaker muscles, and are more likely to injure themselves in a fall because their muscles
        don't react as well. Muscle loss occurs at about the rate of 1% per year. Women's muscles, like their bones, are
        normally smaller than men's, and estrogen contributes significantly to these differences. TNF can produce very
        rapid loss of tissue including bone, and in general, it rises with aging. Some of the people who like to say
        that "osteoporosis is caused by estrogen deficiency" know about the destructive actions of TNF, and argue that
        it rises at menopause "because of estrogen deficiency." There are very good reasons for rejecting that argument;
        the experiments sometimes seem to have been designed purely for propaganda purposes, using toxic levels of
        estrogen for a specific result. One researcher noted that the effects of estrogen on cells in vitro are
        biphasic: Low doses increased TNF, high doses decreased TNF. Everyone knows that unphysiologically high doses
        (50 or 100 or more times above the physiological level of around 0.25 micrograms per liter) of estrogen are
        toxic to cells, producing functional and structural changes, and even rapid death. So, when a researcher who
        wants to show estrogen's "bone protective" effect of lowering TNF adds a lethal dose of estrogen to his cell
        culture, he can conclude that "estrogen inhibits TNF production." But the result is no more interesting than the
        observation that a large dose of cyanide inhibits breathing. TNF is produced by endotoxin, and estrogen
        increases the amount of endotoxin in the blood. Even without endotoxin, though, estrogen can stimulate the
        production of TNF. Lactic acid and unsaturated fats and hypoxia can stimulate increased formation of TNF.
        Estrogen increases production of nitric oxide systemically, and nitric oxide can stimulate TNF formation. How
        does TNF work, to produce tissue damage and wasting? It causes cells to take up too much calcium, which makes
        them hypermetabolic before it kills them. It increases formation of nitric oxide and carbon monoxide, blocking
        respiration. TNF can cause a 19.5 fold increased in the enzyme which produces carbon monoxide (Rizzardini, et
        al., 1993), which blocks respiration. All of the normal conditions associated with high estrogen also are found
        to involve increased production of TNF, and treatment of animals with estrogen clearly increases their TNF.
        Premature ovarian failure (with low estrogen levels) leads to reduced TNF, as does treatment with antiestrogens.
        If bone resorption is significantly regulated by TNF, then it should be concluded that increased estrogenic
        influence will tend to produce osteoporosis. Tamoxifen, which has some estrogenic effects, including the
        inhibition of osteoclasts, can kill osteoclasts when the dose is high enough. The inhibition of osteoclast
        activity by either estrogen or tamoxifen is probably a toxic action, that has been characterized as "beneficial"
        by the estrogen industry simply because they didn't have any better argument for getting women to use their
        products. Some types of dementia, such as Alzheimer's disease, involve a life-long process of degeneration of
        the brain, with an inflammatory component, that probably makes them comparable to osteoporosis and
        muscle-wasting. (In the brain, the microglia, which are similar to macrophages, and the astrocytes, can produce
        TNF.) The importance of the inflammatory process in Alzheimer's disease was appreciated when it was noticed that
        people who used aspirin regularly had a low incidence of that dementia. Aspirin inhibits the formation of TNF,
        and aspirin has been found to retard bone loss. In the case of osteoporosis (A. Murrillo-Uribe, 1999), as in
        Alzheimer's disease, the incidence is two or three times as high in women as in men. In both Alzheimer's disease
        and osteoporosis, the estrogen industry is arguing that the problems are caused by a suddenly developing
        estrogen deficiency, rather than by prolonged exposure to estrogen. Similar arguments were made fifty years ago
        regarding the nature of the menopause itself--that it was caused by a sudden decrease in estrogen production.
        The evidence that has accumulated in the last forty years has decisively settled that argument: Menopause is the
        result of prolonged exposure to estrogen. (Even one large dose destroys certain areas in the brain, and chronic,
        natural levels damage the nerves that regulate the pituitary. Overactivity of the pituitary leads to many other
        features of aging.) The links between estrogen and TNF appear to be essential factors in aging and its diseases.
        Each of these substances has its constructive, but limited, place in normal physiology, but as excitatory
        factors, they must operate within the appropriate constraints. The basic constraint is that resources, including
        energy and oxygen, must be available to terminate their excitatory actions. Adequate oxygen, a generous supply
        of carbon dioxide, saturated fats, thyroid, and progesterone restrain TNF, while optimizing other cytokines and
        immune functions, including thymic protection. In the development of the organism and its adaptive functions,
        there are patterned processes, functional systems, that can clarify the interactions of growth and atrophy. The
        respiratory production of energy and carbon dioxide, and the respiratory defect in which lactic acid is
        produced, correspond to successful adaptation, and to stressful/excitotoxic maladaptation, respectively.
        Excitotoxicity, and Meerson's work on the protective functions of the antistress hormones, have to be understood
        in this framework. This framework integrates the understanding of cancer metabolism with the other stress
        metabolisms, and with the metabolism of normal growth. Unsaturated fats, iron, and lactic acid are closely
        related to the actions and regulation of TNF, and therefore they strongly influence the nature of stress and the
        rate of aging. The fact that cancer depends on the presence of polyunsaturated fats probably relates to the
        constructive and destructive actions of TNF: The destructive effects such as multiple organ failure/congestive
        heart failure/shock-lung, etc., apparently involve arachidonic acid and its metabolites, which are based on the
        so-called essential fatty acids. When oxygen and the correct nutrients are available, the hypermetabolism
        produced by TNF could be reparative (K. Fukushima, et al., 1999), rather than destructive. Stimulation in the
        presence of oxygen produces carbon dioxide, allowing cells to excrete calcium and to deposit it in bones, but
        stimulation in the absence of oxygen produces lactic acid and causes cellular calcium uptake. It is in this
        context that the therapeutic effects of saturated fats, carbon dioxide, progesterone, and thyroid can be
        understood. They restore stability to a system that has been stimulated beyond its capacity to adapt without
        injury.

        <strong>Fatigue, aging, and recuperation</strong>
        <strong></strong>
        <hr />- Old people and sick people tire easily. Surprisingly, little is known to explain that common fact.-
        Myths about lactic acid and oxygen debt have misdirected most fatigue research.- The cellular processes involved
        in fatigue overlap with those of aging.- Knowledge about the mechanisms of fatigue should be useful in
        preventing some tissue swelling disorders, organ failure, degenerative calcification, and other energy-related
        problems.&nbsp;<hr />GLOSSARY:* Uncoupling--In cellular respiration, oxidation of "fuel" in the mitochondrion is
        coupled to the phosphorylation of ADP, forming ATP. Uncouplers are chemicals that allow oxidation to proceed
        without producing the usual amount of ATP.* DNP--Dinitrophenol, an uncoupler that was once popular as a
        weight-loss drug.* NAD+ and NADH--Nicotinamide adenine dinucleotide, and its reduced form are coenzymes for many
        oxidation and reduction reactions in cells.* Hyperammonemia--The presence of too much ammonia in the blood.*
        Vicinal water--water near surfaces, especially hydrophobic surfaces, that is physically and chemically different
        from ordinary water.* Hydrophobic--insoluble in water, a nonpolar oil-like molecule that repels water.<hr
        />Unlike the somewhat technical medical concept of "stress," the idea of fatigue is something everyone
        understands, to some extent. Hans Selye's studies of stress weren't widely accepted until about 40 years after
        their publication, but some of the main investigators of the fatigue phenomenon are still practically unknown in
        the universities, many years after they published their work.&nbsp;Several things have kept fatigue research
        from advancing, including the common feeling that fatigue is already sufficiently understood, and that it is
        somehow trivial, compared to problems such as growth, reproduction, and disease.Fatigue is usually described as
        decreased responsiveness resulting from over-exertion: For example, a muscle's decreased strength or speed of
        contraction, or a nerve's decreased speed of conduction, or a sense organ's decreased ability to detect or to
        discriminate. Another meaning of fatigue, a decreased resistance or strength, can be applied to materials, as
        well as to some biological functions, for example when fatigue leads to sickness or
        infections.&nbsp;"Responsiveness" implies sensitivity, and decreased sensitivity to stimulation can be seen in
        fatigued sense organs, nerves, muscles, and many other types of cell--immune cells, secretory cells, etc. Even
        plant cells have very similar processes of excitability that can be depleted by repetition.In a series of
        lectures to the Royal Society in England (1895-1901), the physicist Jagadis Chandra Bose described work that at
        first excited, and then disturbed, many physicists and biologists. He had invented devices for both producing
        and detecting electromagnetic waves, and he had been the first to produce millimeter length radio waves
        (microwaves). In Marconi's first transatlantic radio transmission Bose's signal detecting device was used. This
        device was based on the fact that two pieces of metal in superficial contact became electrically fused (cohered)
        in the presence of an electrical or electromagnetic field. After they cohered, a mechanical shock would separate
        them, breaking the electrical fusion.When Bose was experimenting with his "self-restoring coherer," a
        semiconducting device that spontaneously broke the connection without being mechanically shaken, he observed
        that it became insensitive after prolonged use, that is, it lost its self-restoring capacity, but that after a
        rest, it recovered its sensitivity. He recognized the complex behavior of his instrument as being very similar
        to the electrical physiology of living cells.He then began a series of experiments on plants, animals, and
        minerals, that showed similar responses to all kinds of stimulation, including mechanical and thermal and
        electromagnetic.The idea of metal fatigue wasn't new, but Bose was able to think far beyond the ideas of the
        metallurgists. Biologists were thinking of electrical responsiveness as a defining feature of life, and Bose
        demonstrated that plants had electrical responsiveness very similar to that of animals, but also that similar
        reactions could be demonstrated in minerals.This was what disturbed the English scientists. Sensitivity,
        irritability, fatigue, and memory were supposed to be special properties related to life, and maybe to
        consciousness. For the Englishmen, there were religious implications in this Hindu's research.There were several
        reasons that European and American scientists couldn't accept the universal nature of the electrical properties
        that they were studying in animals. One of their motives was to see life as something immaterial, or of an
        absolutely different nature than inorganic matter. Another problem had to do with the developing belief that the
        special properties of life were enclosed in the hereditary substance of each cell, and that the electrical
        functions of cells were produced entirely by the presence of a membrane, surrounding a drop of water containing
        randomly moving dissolved chemicals.&nbsp; For the membrane electricity theory, it was essential to believe in
        the random behavior of things dissolved in the cell water.So they considered the electrical-mechanical reactions
        and interactions of minerals to be so unlike the processes of life that it was inappropriate to see analogies
        between them. Minerals were composed of atoms, and, according to the doctrine of the time, they could have no
        "physiological" functions except on the atomic scale. It was more than 20 years before mainstream physicists
        began thinking about "delocalized" forces and fields in minerals.&nbsp;Between 1915 and 1934, Michael Polanyi
        made many observations that made it clear that the old kind of electrical atomism was completely unfounded. The
        behavior of mineral crystals, and the interactions between different phases of material, such as gas or liquid
        with a solid, could be understood only in terms of relatively long-range forces. Polanyi's experiments showed,
        for example, that events on the surface of a crystal modified the strength and deformability of the
        crystal.&nbsp;Many others between 1900 and 1940-- Lepeschkin, Nasonov, Bungenberg de Jong, and Solco Tromp, for
        example--argued that the sensitivity of protoplasm had to be understood in terms of long range order, something
        like a liquid crystalline state of matter that would require some of the kinds of knowledge of matter that were
        being developed by physicists, metallurgists, and a variety of others investigating the condensed states of
        matter.But the mainstream biologists preferred to describe cells in terms that would make impossible any of the
        responsivities or sensitivities seen in the "simple" solid state of minerals. To defend their ideology of the
        immateriality of life, they denied that the subtlest features of matter had anything to do with life, reducing
        life to a debased set of special, merely theoretical, mechanisms. The now defunct physical theory of merely
        localized atomic electrical forces became the paradigm for the new biology. The many demonstrations of coherent,
        ordered physical behavior of the cytoplasm, for example Gurwitch's mitogenic radiation, were dismissed with
        prejudice.&nbsp;During G. W. Crile's long career (1889-1941), understanding shock, biological energy, and
        fatigue were his main concerns. He believed that shock was the result of brain exhaustion, and in one of his
        last publications he showed that the brains from exhausted animals produced less bioluminescence than those from
        rested animals. His importance was in demonstrating that fatigue and shock are systemic conditions of the
        organism, rather than isolated events in muscles and nerves. Recent publications are showing the validity of
        this view. Crile's approach to the prevention and treatment of shock was based on isolating the damaged area
        with local anesthetics. Blocking the nerves from one injured part of the body, for example the sciatic nerve in
        the leg, could preserve energy production (and normal cell functions) throughout the rest of the body.About 30
        years earlier (1901), Vvedensky had demonstrated that some types of fatigue appear to be a defensive blocking of
        responsiveness, such that intense stimulation would produce no response, while weak stimulation could sometimes
        produce a response. These changes affected cell functions in a variety of ways, that he called narcosis and
        parabiosis.There have been two popular ways to "explain" fatigue, one by saying that the cell's energy (usually
        thought of as ATP or glycogen) is used up, the other saying that the accumulation of a metabolic product
        (usually lactic acid) prevents further functioning. The obvious problem with these explanations is that the
        fatigue response is quite independent of those metabolic changes. Another problem is that those ideas don't
        explain the real changes that occur in cells that are demonstrating fatigue.Fatigued cells take up water, and
        become heavier. They also become more permeable, and leak. When more oxygen is made available, they are less
        resistant to fatigue, and when the organism is made slightly hypoxic, as at high altitude, muscles have more
        endurance, and are stronger, and nerves conduct more quickly. These facts don't fit with the standard model of
        the cell, in which its sensitivity is strictly governed by the behavior of its "membrane." (For example, how can
        a membrane leak large molecules at the same time that it is intact and causing the cell to swell osmotically?)
        They are consistent with the model of the cell that treats protoplasm as a special phase of matter.Another
        feature of fatigue (and often of aging, stress, and sickness) is that the relaxation of muscles is retarded and
        impaired.Hypothyroidism causes muscle relaxation to be slowed, both in skeletal muscles and in the heart. F/Z.
        Meerson showed that stress causes heart muscles to be exposed to increased calcium, followed by breakdown of
        fats and proteins, and that these changes keep the injured heart in a continuous state of partial contraction,
        making it stiff, and resistant to complete contractile shortening. When many cardiologists talk about the
        heart's stiffness, they are thinking of muscular thickening and fibrosis, but those are late consequences of the
        kind of contractile, unrelaxed stiffness that Meerson described.The hypothyroid heart does eventually become
        fibrotic, but before that, it is just unable to relax properly, and unable to contract fully. This failure to
        empty fully with each contraction is a kind of "heart failure," but it can be corrected very quickly by
        supplementing thyroid. Even the fibrotic heart can recover under the influence of adequate thyroid.The analogy
        of the "coherer" would suggest that the overstimulated muscle isn't able to decohere itself, until it has had a
        rest. It responds to stimulation, lets the energy flow, but then can't turn it off, and the energy keeps
        flowing, because of a change in physical state.&nbsp;Albert Szent-Gyorgyi was probably the first person to
        seriously investigate the semiconducting properties of living material. Since he was aware of W.F. Koch's idea
        of a free radical catalyst to support oxidative metabolism, his suggestion in 1941 that cellular proteins could
        function as electrical conductors (or semiconductors) was very likely based on his research in cellular
        respiration, as well as on his work with muscle proteins. He had observed that ATP lowers the viscosity of a
        solution of the muscle protein myosin, and that it would cause a filament formed by precipitating myosin to
        contract. The polymerization and contraction of proteins under the influence of free radicals was at the heart
        of F.W. Koch's therapeutic ideas, but Koch's work was about 100 years too early, by medical
        standards.Szent-Gyorgyi observed that, although ATP was involved in the contraction of muscles, its post-mortem
        disappearance caused the contraction and hardening of muscles known as rigor mortis. When he put hardened dead
        muscles into a solution of ATP, they relaxed and softened. The relaxed state is a state with adequate energy
        reserves.After Szent-Gyorgyi moved to the U.S., in 1947, he demonstrated the effect of muscle cytoplasm on the
        behavior of fluorescent substances, which was analogous to that of ice, until the muscle was stimulated. During
        contraction, the fluorescent material behaved as it would in ordinary liquid water. This effect involved the
        stabilization of the excited state of electrons. This single demonstration should have caused biologists to
        abandon the membrane theory of cellular excitation, and to return to basic physics for their understanding of
        cell behavior. The implications of Szent-Gyorgyi's work were enormous for biology and medicine, and even for the
        understanding of semiconductors, but most of the world was hypnotized by a simple textbook model of cell
        membranes.Szent-Gyorgyi also demonstrated that the combination of properly balanced electron donors and electron
        acceptors (D-A pairs) would cause a muscle to contract. He compared this to "doping" an inorganic
        superconductor, to regulate its electronic behavior. Although these experiments were done half a century after
        Koch's application of free radical chemistry to medicine, they still didn't rouse the pharmaceutical industry
        from its toxic slumber.I suspect that it was Szent-Gyorgyi's research with those interesting electronic
        properties of cellular water and proteins that in 1960 gave Linus Pauling the idea to explain anesthesia,
        specifically noble gas anesthesia, in terms of water clathrate formation, the restructuring of cellular water by
        the hydrophobic atom or molecule of an anesthetic. His suggestion caused a reaction among biologists that
        discouraged research into the subject for about 40 years.Gilbert Ling's view of cytoplasmic structure gives a
        different emphasis to the function of electrons, which I think is an essential complement to Szent-Gyorgyi's
        view. Ling's emphasis is on how the inductive effect of adsorbed substances (for example, ATP and progesterone
        has powerful adsorptive effects) on proteins changes the charge concentration on ionizable groups. When the
        charge concentration is in one configuration (more acidic), the preferred counterion is potassium, and in
        another (less acidic) configuration, it is sodium.&nbsp;Gilbert Ling's biophysical calculations were useful to
        physical chemists, and were soon put to practical use for understanding ion exchange resins, such as water
        softeners. Many sorts of evidence showed their validity for cell physiology, but nearly all biologists rejected
        them, preferring to talk about membranes, pumps, and channels, despite the evidence showing that the properties
        ascribed to those are simply impossible. NMR imaging (MRI) was developed by Raymond Damadian specifically as an
        application of Ling's description of cell physiology.Although metals are conductors, the function of the
        coherers of Bose and others shows that the surface is a semiconductor, that requires the slight excitation of an
        electromagnetic wave to become conductive, at which point the conduction band of electrons in the metal becomes
        coherent and extends from one particle into the others. The surface of any phase of a substance has electronic
        properties distinct from those of the bulk phase, and in a sense the interface constitutes a special phase of
        matter.&nbsp; When the electrons of the interface lose their special properties, the structure of the whole
        system changes.When a muscle cell is stimulated enough to cause a contraction, the interruption of its resting
        phase causes a shift in the charge concentration on the proteins, potassium ions are exchanged for sodium ions,
        calcium ions enter, and phosphate ions separate from ATP, and are replaced by the transfer of phosphate to ADP
        from creatine phosphate.&nbsp;Since the quantum physicist E. Schroedinger wrote his book, Time's Arrow, people
        have often thought of life in terms of negentropy, going against the general tendency of entropy to increase,
        except for aging and death, which are seen as obeying a law of increasing entropy. But A. Zotin investigated
        organisms, rather than abstractions about electrons, and shows that aging involves a decrease in entropy, and a
        slowing of metabolism. The decrease of entropy with aging, according to his view, would be analogous to
        crystallization, a sort of progressive freezing.When a nerve is stimulated, it releases energy suddenly, and
        much of this heat seems to be the result of a change of structure in the cytoplasm, since (in crustaceans'
        nerves, which can function at low temperature) during the resting recovery of the nerve, its temperature goes
        slightly below the ambient temperature, despite the release of some heat from the chemical changes of
        metabolism, stimulated by the nerve's activity.&nbsp;When a physical change is endothermic, as the nerve's
        recovery is, that can be interpreted as an increase in overall entropy, as when a rubber band spontaneously
        contracts, and becomes cooler.Bose's rested coherer, which, with time, spontaneously recovered its
        semiconductive (i.e., relatively insulating) property, wasn't being powered by metabolism. As the particles
        returned to their relatively isolated state, there was a decrease of order, and the change was probably somewhat
        like the spontaneous energy change in the stimulated crustacean nerve. I assume the change would result from the
        absorption of environmental heat, possibly with infrared resonance with electron conduction bands.Seeing the
        structure of the cytoplasm as something like a spring-driven mechanism, able to bounce between two states or
        "phases," makes it easier to see cellular fatigue as something different from the various metabolic energy
        sources, ATP, glycogen, and oxygen, which--contrary to conventional assumptions--aren't closely tied to the
        functional losses occurring in fatigue.The role of metabolism, then, becomes analogous to the role of the
        "tapper" in the early forms of the coherer.Water in its normal state is a dielectric. But when it is polarized
        by an electrical charge, or by the presence of a phase boundary, its normal state is altered. This is the
        special interfacial water, or vicinal water. With the movement of ions (mainly potassium, sodium, calcium, and
        magnesium) during excitation, the state of the cellular water is necessarily changed by the presence of
        different substances. In the excited state, cell water is less hydrophobic, more hydrophilic than in the relaxed
        state. A network of "hydrophobic" interactions extends through the relaxed cell. One of the properties of a
        dielectric is that it tends to move into the space between charges, with a force similar in principle to that
        involved in dielectrophoresis.&nbsp;In the resting state, potassium is the main inorganic ion, and it is
        associated with acidic groups, such as aspartic and glutamic acid. During excitation, potassium is partly
        exchanged for sodium, which becomes the preferred counter-ion for the acid groups, and calcium enters the cell
        along with the sodium. Potassium's interaction with water is very weak (its hydration has been called negative),
        allowing water to form the structures that are stable in the presence of hydrophobic surfaces. Sodium and
        especially calcium (smaller atoms, with higher surface charge concentration) powerfully interact with water
        molecules, more strongly than water interacts with itself, disrupting the delicate somewhat hydrophobic
        structures of the intracellular water.(Calcium, with its two charges, has important binding and stabilizing
        functions in the resting cell. In the excited cell, these internal calcium ions are released, while
        extracellular calcium ions enter the cell.)With the increased movement of charged particles during the
        stimulation of a nerve or muscle, as one kind of counterion is exchanged for another, and the destruction of
        some of the water's structure, there are more opportunities for bulk dielectric water to enter cells,
        interfering with the arrangement of proteins, and tending to cause swelling and separation of the structural
        elements of the cell. Electron micrographs of fatigued muscle show a remarkable separation of the actin and
        myosin proteins.In the excited state, NMR studies show that cell water behaves more like bulk water, that is,
        its molecular movements are relatively free, indicating the momentary loss of the interfacial state. In this
        state, the uptake of water, and the fatigue-related swelling of nerves and muscles, would be driven at least
        partly by the principle that a dielectric tends to be pulled into the spaces separating charges. The bulk water
        that enters a cell during the breakdown of vicinal water functions as an extraneous material somewhat beyond the
        cell's control.These bulk-like high dielectric properties of water in the excited cellular state can explain
        many changes of enzyme activity. Previously nonpolar lipids would develop a negative surface charge (from
        accumulating hydroxyl groups: Marinova, et al., 1996), which would tend to increase their oxidation and
        degradation. With the loss of the interfacial water, the cell's high energy resting state is replaced by an
        active mobilization of its resources, to maintain and restore the cell's structure. Metabolic energy begins to
        flow into the processes of restoration, serving the function of the tapper in the earliest coherers.Looking at
        fatigability, muscle contraction, and nerve conduction in a variety of situations, we can test some of the
        traditional explanations, and see how well the newer "bioelectronic" explanations fits the facts. Osmotic
        pressure, hydrostatic pressure, atmospheric pressure, and the degree of metabolic stimulation by thyroid hormone
        affect fatigue in ways that aren't consistent with the membrane-electrical doctrine.The production of lactic
        acid during intense muscle activity led some people to suggest that fatigue occurred when the muscle wasn't
        getting enough oxygen, but experiments show that fatigue sets in while adequate oxygen is being delivered to the
        muscle. Underwater divers sometimes get an excess of oxygen, and that often causes muscle fatigue and soreness.
        At high altitudes, where there is relatively little oxygen, strength and endurance can increase.An excess of
        oxygen can slow nerve conduction, while hypoxia can accelerate it. (Increasing the delivery of oxygen at higher
        pressure doesn't increase the cellular use of oxygen or decrease lactic acid production in the exercising muscle
        [Kohzuki, et al., 2000], but it will increase lipid peroxidation.)High hydrostatic pressure causes muscles to
        contract, though for many years the membrane-doctrinaires couldn't accept that. Underwater divers experience
        brain excitation under very high pressure. Since vicinal water has a larger volume than ordinary water
        (analogous to the expansion when ice is formed, though the volume increase in cell water is slightly less, about
        4%, than in ice, which is 11% more voluminous than liquid water), compression under high pressure converts
        vicinal cell water to the state that occurs in the excited cell, the way ice melts under pressure. The excited
        state exists as long as water remains in that state.These changes of state under pressure are reminiscent of
        Bose's use of pressure in some of his coherers, and of the fact that pressure alters the sensitivity of
        electrons in a semiconductor, by altering their "band gap," the amount of energy needed to make them enter the
        conductive zone.One of the early demonstrations that cell water undergoes a phase change during muscle
        contraction involved simply measuring the volume of an isolated muscle. With stimulation and contraction, the
        volume of the muscle decreases slightly. (The muscle was immersed in water in a sealed chamber, and the volume
        decrease in the whole chamber was measured.)&nbsp; This corresponds to the conversion of vicinal water to
        bulk-like (dielectric) water.&nbsp; (The threatening implications of those experiments with spontaneous volume
        change were very annoying to many biologists of my professors' generation.)In the stimulated state, the cell's
        uptake of water from its environment coincides closely with its electrical and thermal activity, and its
        expulsion of water coincides with its recovery. In a small nerve fiber, or near the surface of a larger fiber,
        these changes are very fast, and in a large muscle the uptake of water is faster than the flow of water from
        capillaries can match, but it will become massive if stimulation is continued for several minutes. For example,
        two minutes of stimulation can cause a muscle's overall weight to increase by 6%, but its extracellular
        compartment loses 4%, so the muscle cells gain much more than 6% of their weight in that short time (Ward, et
        al., 1996). The water that is taken up by cells is taken from the blood, which becomes relatively dehydrated and
        thicker in the process.The belief in "semipermeable membranes" (which hasn't been a viable explanation of cell
        physiology for a very long time) forces people to explain cell swelling osmotically, which means that they
        simply assume that the number of solute particles inside the cell has drastically increased in a very short
        time. In Tasaki's experiments (1980, 1981, 1982), the swelling in a nerve coincides with the electrical action
        potential, which, according to the osmotic explanation, means that a very large increase in internal osmolarity
        happened in essentially no time. The action potential comes and goes in about 2 milliseconds. The swelling also
        coincides with heat production and shortening of the nerve fiber. The shrinkage of the nerve fiber after the end
        of the action potential may be just as rapid, and the membrane theory offers no explanation for that, either.
        (But the restoration of the unswollen state can be very prolonged, depending on conditions extrinsic to the
        particular muscle or cell.) Troshin's survey of the theory of osmotic regulation of cell volume showed that the
        idea of the cell as a membrane osmometer was false, but very few biologists read his book.Since the excited or
        fatigued muscle or nerve swells and gains weight, it's interesting to see what happens to their sensitivity and
        strength when they are exposed to hypotonic solutions that tend to promote swelling, or to hypertonic solutions,
        that help to prevent swelling.In a hypotonic solution, cells are excited (Lang, et al., 1995: "Exposure of
        aortic strips from guinea-pigs to hypotonic extracellular fluid is followed by marked vasoconstriction..."), but
        the early excitation is followed by decreased responsiveness (Ohba, et al., 1984: "Exposure of muscle to
        hypotonic solutions [70% of normal solution] produced initially a transient increase in twitch after which
        twitch declined below the control level"). Hypertonic solutions tend to produce relaxation in normal muscles,
        including the aorta (Tabrizchi, 1999), but when muscle function is impaired (especially in the circulatory
        system, as in shock) they improve contractile function (Elgjo, et al., 1998: "The maximum contraction force
        measured in isolated right papillary muscles ex vivo was significantly greater in HSD-treated than normal
        saline-treated animals"). Athletes can lose 4% of their weight by dehydration without decreasing their muscular
        strength.Hypothyroidism tends to cause loss of sodium from the blood, and the hyponatremia sometimes leads to a
        generalized hypotonicity of the body fluids. The thyroid hormone itself functions as an antioxidant, but much of
        its protective effect against cell damage is probably the result of preventing cell swelling and accelerating
        the removal of calcium from the cell. (Swelling, like fatigue, causes intracellular calcium to increase.)The
        electrical surface charging of lipids in bulk water probably accounts for the increased lipid peroxidation that
        occurs in fatigue, edema, and hypothyroidism, when water loses its normal partial hydrophobicity. Increased
        carbon dioxide is known to decrease lipid peroxidation, and its production requires adequate thyroid
        function.Thyroid stimulation of oxygen consumption tends to prevent lactic acid production, because it keeps the
        cytoplasm in a state of relative oxidation, i.e., it keeps the concentration of NAD+ hundreds of times higher
        than that of NADH. NADH is required for the conversion of pyruvate to lactate. It is also the source of reducing
        potential in many kinds of toxic redox cycling, that generate lipid peroxides, and it maintains the sulfhydryl
        system, involving the balance of reduced glutathione with the sulfhydryl-disulfide system of protein bonds,
        which governs the cell's electronic state and affects its balance of hydrophobicity and hydrophilicity.The
        harmful lipid oxidation interferes with energy production and regulatory processes, and is responsible for some
        of the prolonged effects of fatigue, swelling, and hypothyroidism. These lingering effects of lipid oxidation
        are undoubtedly amplified by the presence of larger amounts of unstable polyunsaturated fats, as the energy
        demands of the fatigued state mobilize free fatty acids from the tissues.&nbsp;One of the oldest tests for
        hypothyroidism was the Achilles tendon reflex test, in which the rate of relaxation of the calf muscle
        corresponded to thyroid function--the relaxation is slow in hypothyroid people. Water, sodium and calcium are
        more slowly expelled by the hypothyroid muscle. Exactly the same slow relaxation occurs in the hypothyroid heart
        muscle, contributing to congestive heart failure, because the semi-contracted heart can't receive as much blood
        as the normally relaxed heart. The hypothyroid blood vessels are unable to relax properly, contributing to
        hypertension. Hypothyroid nerves don't easily return to their energized relaxed state, leading to insomnia,
        paresthesias, movement disorders, and nerves that are swollen and very susceptible to pressure damage.&nbsp;With
        aging, hypothyroidism, stress, and fatigue, the amount of estrogen in the body typically rises. Estrogen is
        catabolic for muscle, and causes systemic edema, and nerve excitation. It weakens muscle contraction in the
        bladder, although it lowers the threshold for stimulation of sensation and contraction (Dambros, et al., 2004).
        This is the pattern that causes people to wake up frequently, to pass a small amount of urine. (Progesterone has
        the opposite effect in the urinary bladder, raising the threshold of response, but strengthening contraction, as
        it does in the gallbladder.) Estrogen lowers stimulation threshold in the gallbladder, as it does in the brain.
        Part of its excitatory action might be the result of increased hypotonic tissue water, but its effects on nerve
        thresholds are practically instantaneous.&nbsp;In 1971 and '72, I gave some of the reasons for thinking that
        estrogen's biological effects result from its direct effects on cell water, causing it to become more like bulk
        (high dielectric) water. For example, NMR (spin echo) of estrogen treated uterus and of the uterus from an old
        animal were closer to bulk water than that of a young animal. Estrogen, like fatigue or excessive oxygen, slows
        nerve conduction.Lactic acid production increases with fatigue, aging, hypothyroidism, estrogen excess, and
        other inefficient biological states. Its presence, when oxygen is available, indicates that something is
        interfering with efficient oxidative energy metabolism. Ammonia, free fatty acids, and various inflammatory
        cytokines are also likely to increase in those stress states.A dangerously high level of ammonia in the blood
        (hyperammonemia) can be produced by exhaustive exercise, but also by hyperbaric oxygen (or a high concentration
        of oxygen), by high estrogen, and by hypothyroidism. It tends to be associated with an excess of lactic acid,
        probably because ammonia stimulates glycolysis. Excess oxygen, like hypothyroidism, is equivalent to
        "hyperventilation," in producing an abnormally low level of carbon dioxide in the blood. The Krebs cycle, during
        stress, is limited by the unavailability of carbon dioxide. These factors result in the waste of glucose,
        turning it into lactic acid, rather than carbon dioxide and energy. In these ways, the metabolism of fatigued
        muscle (or any cell under stress) is similar to tumor metabolism.Hyperammonemia disturbs excitatory processes,
        and can cause seizures, as well as stupor, and is probably involved in mania and depression. Lithium happens to
        complex electronically with ammonia, and I think that accounts for some of its therapeutic effects, but carbon
        dioxide is the main physiological factor in the elimination of ammonia, since it combines with it to form urea.
        The changes in cell water in the excited/fatigued state represent an increase in the water's "structural
        temperature," and that would imply that less carbon dioxide could remain dissolved during excitation.Eating
        sugar and using caffeine, which increases the oxidation of sugar (Yeo, et al., 2005), can reduce fatigue, both
        subjectively and objectively. Metabolically, they increase the production of carbon dioxide. Increasing sugar
        decreases the liberation and use of fatty acids, and by a variety of mechanisms, helps to lower the production
        of ammonia, lactate, and inflammatory cytokines. (Lactic acid, in combination with acidosis and free
        phospholipids, can interfere with efficient cell functions [Pacini and Kane, 1991; Boachie-Ansah, et al.,
        1992].) Free fatty acids release tryptophan from albumin, contributing to the formation of serotonin, which
        increases the sense of fatigue.Aspirin and niacin help to prevent fatigue symptoms, and to prevent many of the
        harmful systemic oxidative after-effects. (Both are antilipolytic; aspirin uncouples mitochondria.)Uncoupling of
        mitochondrial oxidative metabolism from ATP production helps to consume the sugar which otherwise would be
        diverted into lactic acid, and converts it into carbon dioxide instead. Mild hypoxia, as at high altitude,
        suppresses lactic acid production ("the lactate paradox"), and increases the amount of carbon dioxide in
        tissues.&nbsp;Aspirin and thyroid (T3) increase uncoupling. A drug that used to be used for weight reduction,
        DNP, also uncouples mitochondrial metabolism, and, surprisingly, it has some of the beneficial effects of
        thyroid and aspirin. It stimulates the consumption of lactic acid and the formation of carbon dioxide.The
        squirrel monkey, which on average weighs about 2 or 3 pounds as an adult, lives much longer than other mammals
        of its size, usually about 20 years, as long as 27. It has an extremely high rate of oxygen consumption. This is
        probably the result of natural uncoupling of the mitochondria, similar to that seen in long-lived mice. Mice
        with 17% higher resting oxygen consumption lived 36% longer than slow respiring mice of a related strain
        (Speakman, et al., 2004).Living at a high altitude, people tend to eat more and stay leaner than when they live
        near sea level. Apparently, their mitochondria are relatively uncoupled, and they have more mitochondria, which
        would partly account for their lower production of lactic acid during muscular exertion. Increased thyroid
        activity, too, tends to increase mitochondrial mass, as well as their uncoupling.Most of the things that we
        think of as fatigue result from disturbances of the hydration of cells, whose sensitivity, composition, and
        structure change according to the extent of the disturbance. The hydration is governed by the cells'
        "electrical" properties, which are regulated by internal metabolic processes and by systemic processes. When
        cellular fatigue reaches a certain point, only the interactions of all the organs can restore stable cellular
        structure and functions. The liver eliminates lactic acid and ammonia, the adrenals and gonads provide
        stabilizing steroids, and the brain alters activity and behavior, in ways that can reverse most of the effects
        of fatigue.But, when the tissues contain large amounts of polyunsaturated fats, every episode of fatigue and
        prolonged excitation leaves a residue of oxidative damage, and the adaptive mechanisms become progressively less
        effective. When the most powerful adaptive mechanisms, such as the timely synthesis of progesterone,
        pregnenolone, DHEA, T3, and the inhibitory transmitters, GABA and glycine, fail, then some of the primitive
        defense mechanisms will become chronically activated, and even sleep may fail to restore normal cellular water
        and metabolism. Hyperventilation often becomes a problem, making capillary leakiness worse.Water in the body
        occupies three major compartments--blood vessels, extracellular matrix, and the moist cell substance itself--and
        its condition in each compartment is a little different, and subject to variation. There are no textbooks in use
        in the U.S. that treat intracellular water scientifically, and the result is that physicians are confused when
        they see patients with edema or with disturbances in blood volume. It rarely occurs to physicians to consider
        disturbances of water distribution in problems such as chronic fatigue, fibromyalgia, sleep disturbances,
        frequent urination, slow bladder emptying, anxiety, paresthesia, movement disorders, the tunnel syndromes, or
        even slowed thinking, but "intracellular fatigue" leading to over-hydration is probably the central problem in
        these, and many other degenerative and inflammatory problems.&nbsp;The improvements in cell functions and water
        distribution that are inversely related to oxygen pressure, and directly related to carbon dioxide, won't be
        discussed in medical textbooks until they have given up the idea of membrane-regulated cells.&nbsp;The
        "treatment" for intracellular fatigue consists of normalizing thyroid and steroid metabolism, and eating a diet
        including fruit juice, milk, some eggs or liver, and gelatin, assuring adequate calcium, potassium sodium, and
        magnesium, and using supplements of niacin-amide, aspirin, and carbon dioxide when necessary. Simply increasing
        carbon dioxide decreases lactic acid and ammonia, increases GABA (the sleep improving nerve inhibitor), and
        regulates mineral and water disposition.One of the outcomes of the study of the physiology of fatigue is that it
        leads to a better understanding of cells in general, and offers some new insights into aging, inflammation, and
        a variety of stress-related diseases.<h3>REFERENCES</h3>Minerva Med. 1966 Feb 21;57(15):599-604. [Chronic

                GLOSSARY</strong>
        </p>
        <p>
            <strong>Aerobic glycolysis,</strong> the conversion of glucose to lactic acid even in the presence of
            oxygen. The presence of oxygen normally restrains glycolysis so that glucose is converted to carbon dioxide
            instead of lactic acid.
        </p>
        <p>
            <strong>Anaerobic glycolysis,</strong> the increased conversion of glucose to lactic acid when the supply of
            oxygen isn't sufficient, which is a normal event during intense muscle action.
        </p>

        <p>
            <strong>"Warburg Effect"</strong> refers to Otto Warburg's observation that cancer cells produce lactic acid
            even in the presence of adequate oxygen. Cancer cells don't "live on glucose," since they are highly adapted
            to survive on protein and fats.
        </p>
        <p>
            <strong>Pasteur Effect,</strong> the normal response of cells to restrain glycolysis in the presence of
            adequate oxygen.
        </p>

        <p>
            <strong>Crabtree Effect,</strong> observed originally in yeast, refers to the inhibition of respiration in
            the presence of glucose. This occurs in cancers (e.g., Miralpeix, et al., 1990) and in rapidly proliferating
            normal cells (e.g., Guppy, et al., 1993).
        </p>
        <p>
            <strong>"Cancer metabolism"</strong> or stress metabolism typically involves an excess of the adaptive
            hormones, resulting from an imbalance of the demands made on the organism and the resources available to the
            organism. Excessive stimulation depletes glucose and produces lactic acid, and causes cortisol to increase,
            causing a shift to the consumption of fat and protein rather than glucose. Increased cortisol activates the
            Randle effect (the inhibition of glucose oxidation by free fatty acids), accelerates the breakdown of
            protein into amino acids, and activates the enzyme fatty acid synthase, which produces fatty acids from
            amino acids and pyruvate, to be oxidized in a "futile cycle," producing heat, and increasing the liberation
            of ammonia from the amino acids. Ammonia suppresses respiratory, and stimulates glycolytic, activity.

            The presence of lactic acid in our tissues is very meaningful, but it is normally treated as only an
            indicator, rather than as a cause, of biological problems. Its presence in rosacea, arthritis, heart
            disease, diabetes, neurological diseases and cancer has been recognized, and recently it is being recognized
            that suppressing it can be curative, after fifty years of denial.
        </p>
        <p>
            The influence of politics on science is so profound that neither historians nor scientists often care to
            consider it honestly and in depth.
        </p>
        <p>
            From the 19th century until the second quarter of the 20th century, cancer was investigated mainly as a
            metabolic problem. This work, understanding the basic chemistry of metabolism, was culminating in the 1920s
            in the work of Otto Warburg and Albert Szent-Gyorgyi on respiration. Warburg demonstrated as early as 1920
            that a respiratory defect, causing aerobic glycolysis, i.e., the production of lactic acid even in the
            presence of oxygen, was an essential feature of cancer. (The formation of lactic acid is normal and adaptive
            when the supply of oxygen isn't adequate to meet energy demands, for example when running.)
        </p>
        <p>
            Many people recognized that this was likely to be the key to the "cancer problem." But in the US, several
            factors came together to block this line of investigation.
        </p>

        <p>
            The world wars contributed to the isolation of German scientists, and Warburg, of the famous Jewish banking
            family, continued his work in Germany with the support of the government, despite his open opposition to
            Nazism. In the years after the war, nothing positive could be said in the US about his work on cancer.
        </p>
        <p>
            The metabolic interpretation of disease that had been making progress for several decades was suddenly
            submerged when government research financing began concentrating on genetic and viral interpretations of
            disease.
        </p>
        <p>
            If an apparently non-infectious disease couldn't be explained on the basis of an inherited
            tendency---insanity, epilepsy, diabetes, toxemia of pregnancy, and cancer, for example---then genetic
            changes occurring in the individual, as a result of chance or a virus, were invoked. Nutrition and other
            conditions of life were until fairly recently said to have no influence on health if the person consumed
            sufficient calories and a minimum amount of the essential vitamins, minerals, and protein. The cult of
            genetic determinism was so powerful that it wasn't affected by the facts.
        </p>
        <p>
            In 1932, a pediatrician, Alexis Hartmann (with M. Senn) in St. Louis, injected intravenously a solution of
            sodium lactate into patients with metabolic acidosis, and several of them survived---despite the fact that
            some of them were already suffering from an excess of lactate. The subsequent widespread use of lactate
            solutions in hospitals has contributed to the general denial of its toxicity.
        </p>
        <p>
            Hartmann and Senn used racemic lactate, that is, a mixture of D-lactate and L-lactate. Our own tissues
            produce mostly L-lactate, but they can produce small amounts of D-lactate; larger amounts are produced by
            diabetics. Intestinal bacteria can produce large amounts of it, and it has many toxic effects. Methylglyoxal
            can be formed from either form of lactate, and it is an important factor in the glycation of proteins. It
            can also be formed from MDA, a product of lipid peroxidation. Protein glycation is an important factor in
            diabetes and aging, but glucose, rather than lactate and polyunsaturated fats, is commonly said to be the
            cause.
        </p>

        <p>
            About 50 years ago, lactate was known to induce the formation of new blood vessels, and for a much longer
            time it has been known to cause vasodilation and edema. In 1968, it was shown to stimulate collagen
            synthesis.
        </p>
        <p>
            Normally, collagen synthesis and neovascularization are caused by lack of oxygen, but lactate can cause them
            to occur even in the presence of oxygen. Maintenance of a normal extracellular matrix is essential for
            normal functioning and cellular differentiation. Abnormally stimulated collagen synthesis probably
            accelerates tumor growth (Rajkumar, et al., 2006).
        </p>
        <p>
            Nervous and hormonal factors can cause lactate to accumulate, even without prior damage to the mitochondria
            (e.g., B. Levy, et al., 2003). Psychological, as well as physical, stress and overactivation of glutamate
            receptors can cause harmful accumulation of lactate in the brain (Uehara, et al., 2005). Rather than just
            being "associated with" tissue damage, lactate directly contributes to the damage, for example in the brain,
            causing nerve cell loss by increasing the release of excitotoxic glutamate (Xiang, et al, 2004). When a
            panic reaction is produced by sodium lactate, the reduction of protective neurosteroids appears to
            contribute to the excitatory state (Eser, et al. 2006); this would make the brain more susceptible to
            damage.
        </p>
        <p>
            Lactate increases blood viscosity, mimics stress, causes inflammation, and contributes to shock. Lactated
            Ringer's solution contributes to the tissue damage caused by shock, when it's used to resuscitate shock
            victims (Deree, et al., 2007, 2008): it contributes to the inflammatory processes associated with shock,
            unlike the use of hypertonic saline and other solutions. Lactate contributes to diabetes, inhibiting the
            ability to oxidize glucose. It promotes endothelial cell migration and leakiness, with increased vascular
            permeability factor (VPF or vascular endothelial growth factor, VEGF) (Nagy, et al. 1985): this can lead to
            breakdown of the "blood-brain barrier."
        </p>

        <p>
            In the brain, lactate can cause nerve damage, increasing intracellular fat accumulation, chromatin clumping,
            and mitochondrial swelling (Norenberg, et al., 1987).
        </p>
        <p>
            The lactate in peritoneal dialysis solution impairs differentiation and maturation of (immune, monocyte
            derived) dendritic cells; according to the authors of the study, "These findings have important implications
            for the initiation of immune responses under high lactate conditions, such as those occurring within tumor
            tissues or after macrophage activation<strong>" </strong>
            (Puig-Kr"ger, et al., 2003).<strong> </strong>
        </p>
        <p>
            Lactate also causes macrophages and synovial fibroblasts to release PGE2, which can contribute to
            inflammation and bone resorption (Dawes and Rushton, 1994). This is the prostaglandin known to activate the
            formation of estrogen (Haffty, et al., 2008).
        </p>
        <p>
            Hartmann's lactated solution has been widely used in hospitals for resuscitation and for patients after
            heart surgery and other stressful procedures, but until recently only a few people have objected to its use,
            and most of the objection has been to the use of racemic lactate, rather than to lactate itself. In recent
            years several studies have compared hypertonic saline (lacking the minerals considered essential since
            Sydney Ringer formulated his solution around 1885), and have found it in some cases superior to the
            "balanced" lactate solution. Even hypertonic glucose, without minerals, has produced good results in some
            studies.
        </p>

        <p>
            A solution containing a large amount of lactate has been used for peritoneal dialysis when there is kidney
            failure, but several studies have compared solutions using bicarbonate instead of lactate, and found that
            they don't cause the severe damage that always happened with the traditional solution.
        </p>
        <p>
            While Warburg was investigating the roles of glycolysis and respiration in cancer,<strong> </strong>a
            physician with a background in chemistry, W.F. Koch, in Detroit, was showing that the ability to use oxygen
            made the difference between health and sickness, and that the cancer metabolism could be corrected by
            restoring the efficient use of oxygen. He argued that a respiratory defect was responsible for
            immunodeficiency, allergy, and defective function of muscles, nerves, and secretory cells, as well as
            cancer. Koch's idea of cancer's metabolic cause and its curability directly challenged the doctrine of the
            genetic irreversibility of cancer that was central to governmental and commercial medical commitments.
        </p>
        <p>
            Albert Szent-Gyorgyi respected Koch's work, and spent years investigating the involvement of the lactate
            metabolites, methylgyoxal and glyoxal, in cell physiology, but since the government's campaign against Koch
            was still active when Szent-Gyorgyi came to the U.S., he worked out many of the implications of Koch's work
            relating to cellular oxidation without mentioning his name.
        </p>

        <p>
            Lactate formation from glucose is increased when anything interferes with respiratory energy production, but
            lactate, through a variety of mechanisms, can itself suppress cellular respiration. (This has been called
            the Crabtree effect.) Lactate can also inhibit its own formation, slowing glycolysis. In the healthy cell,
            the mitochondrion keeps glycolysis working by consuming pyruvate and electrons (or "hydrogens") from NADH,
            keeping the cell highly oxidized, with a ratio of NAD+/NADH of about 200. When the mitochondrion's ability
            to consume pyruvate and NADH is limited, the pyruvate itself accepts the hydrogen from NADH, forming lactic
            acid and NAD+ in the process. As long as lactate leaves the cell as fast as it forms, glycolysis will
            provide ATP to allow the cell to survive. Oxygen and pyruvate are normally "electron sinks," regenerating
            the NAD+ needed to produce energy from glucose.
        </p>
        <p>
            But if too much lactate is present, slowing glycolytic production of ATP, the cell with defective
            respiration will die unless an alternative electron sink is available. The synthesis of fatty acids is such
            a sink, if electrons (hydrogens) can be transferred from NADH to NADP+, forming NADPH, which is the reducing
            substance required for turning carbohydrates and pyruvate and amino acids into fats.
        </p>
        <p>
            This transfer can be activated by the transhydrogenase enzymes in the mitochondria, and also by interactions
            of some dehydrogenase enzymes.
        </p>
        <p>
            The enzyme, fatty acid synthase (FAS), normally active in the liver and fat cells and in the
            estrogen-stimulated uterus, is highly active in cancers, and its activity is an inverse indicator of
            prognosis. Inhibiting it can cause cancer cells to die, so the pharmaceutical industry is looking for drugs
            that can safely inhibit it. This enzyme is closely associated with the rate of cell proliferation, and its
            activity is increased by both cortisol and estrogen.
        </p>

        <p>
            The first biochemical event when a cell responds to estrogen is the synthesis of fat. Estrogen can activate
            transhydrogenases, and early studies of estrogen's biological effects provided considerable evidence that
            its actions were the result of the steroid molecule's direct participation in hydrogen transfers, oxidations
            and reductions. E.V. Jensen's claim that estrogen acts only through a "receptor protein" which activated
            gene transcription was based on his experimental evidence indicating that estrogen doesn't participate in
            oxidation and reduction processes in the uterus, but subsequently his claim has turned out to be false.
        </p>
        <p>
            Glycolysis is very inefficient for producing usable energy compared to the respiratory metabolism of the
            mitochondria, and when lactate is carried to the liver, its conversion to glucose adds to the energy drain
            on the organism.
        </p>
        <p>
            The hypoglycemia and related events resulting from accelerated glycolysis provide a stimulus for increased
            activity of the adaptive hormones, including cortisol. Cortisol helps to maintain blood sugar by increasing
            the conversion of protein to amino acids, and mobilizing free fatty acids from fat stores. The free fatty
            acids inhibit the use of glucose, so the stress metabolism relies largely on the consumption of amino acids.
            This increases the formation of ammonia, yet the combination of glycolysis and fat oxidation provides less
            carbon dioxide, which is needed for the conversion of ammonia to urea. Ammonia stimulates the formation of
            lactate, while carbon dioxide inhibits it.
        </p>
        <p>
            Starving an animal with a tumor increases the stress hormones, providing free fatty acids and amino acids,
            and accelerates the tumor's growth (Sauer and Dauchy, 1987); it's impossible to "starve a tumor," by the
            methods often used. Preventing the excessive breakdown of protein and reducing the release of fatty acids
            from fat cells would probably cause many cancer cells to die, despite the availability of glucose, because
            of lactate's toxic effects, combined with the energy deficit caused by the respiratory defect that causes
            their aerobic glycolysis. Recently, the intrinsically high rate of cell death in tumors has been recognized.
            The tumor is maintained and enlarged by the recruitment of "stem cells." These cells normally would repair
            or regenerate the tissue, but under the existing metabolic conditions, they fail to differentiate properly.
        </p>

        <p>
            The extracellular matrix in the tumor is abnormal, as well as the metabolites and signal substances being
            produced there, and the new cells fail to receive the instructions needed to restore the normal functions to
            the damaged tissue. These abnormal conditions can cause abnormal differentiation, and this cellular state is
            likely to involve chemical modification of proteins, including remodeling of the chromosomes through
            acetylation of the histones (Alam, et al., 2008; Suuronen, et al., 2006). The protein-protective effects of
            carbon dioxide are replaced by the protein-damaging effects of lactate and its metabolites.
        </p>
        <p>
            The ability of lactic acid to displace carbon dioxide is probably involved in its effects on the blood
            clotting system. It contributes to disseminated intravascular coagulation and consumption coagulopathy, and
            increases the tendency of red cells to aggregate, forming "blood sludge," and makes red cells more rigid,
            increasing the viscosity of blood and impairing circulation in the small vessels. (Schmid-Sch"nbein, 1981;
            Kobayashi, et al., 2001; Martin, et al., 2002; Yamazaki, et al., 2006.)
        </p>
        <p>
            The features of the stress metabolism include increases of stress hormones, lactate, ammonia, free fatty
            acids, and fat synthesis, and a decrease in carbon dioxide. Factors that lower the stress hormones, increase
            carbon dioxide, and help to lower the circulating free fatty acids, lactate, and ammonia, include vitamin B1
            (to increase CO2 and reduce lactate), niacinamide (to reduce free fatty acids), sugar (to reduce cortisol,
            adrenaline, and free fatty acids), salt (to lower adrenaline), thyroid hormone (to increase CO2). Vitamins
            D, K, B6 and biotin are also closely involved with carbon dioxide metabolism. Biotin deficiency can cause
            aerobic glycolysis with increased fat synthesis (Marshall, et al., 1976).
        </p>
        <p>
            A protein deficiency, possibly by increasing cortisol, is likely to contribute to increased FAS and fat
            synthesis (Bannister, et al., 1983), but the dietary protein shouldn't provide an excess of tryptophan,
            because of tryptophan's role as serotonin precursor--serotonin increases inflammation and glycolysis
            (Koren-Schwartzer, et al., 1994).
        </p>

        <p>
            Incidental stresses, such as strenuous exercise combined with fasting (e.g., running or working before
            eating breakfast) not only directly trigger the production of lactate and ammonia, they also are likely to
            increase the absorption of bacterial endotoxin from the intestine. Endotoxin is a ubiquitous and chronic
            stressor. It increases lactate and nitric oxide, poisoning mitochondrial respiration, precipitating the
            secretion of the adaptive stress hormones, which don't always fully repair the cellular damage.
        </p>
        <p>
            Aspirin protects cells in many ways, interrupting excitotoxic processes by blocking nitric oxide and
            prostaglandins, and consequently it inhibits cell proliferation, and in some cases inhibits glycolysis, but
            the fact that it can inhibit FAS (Beynen, et al., 1982) is very important in understanding its role in
            cancer.
        </p>
        <p>
            There are several specific signals produced by lactate that can promote growth and other features of cancer,
            and it happens that aspirin antagonizes those: HIF, NF-kappaB, the kinase cascades, cyclin D1, and heme
            oxygenase.
        </p>
        <p>
            Lactate and inflammation promote each other in a vicious cycle (Kawauchi, et al., 2008).
        </p>
        <p>
            The toxic mechanism of bacterial endotoxin (lipopolysaccharide) involves inappropriate stimulation (Wang and
            White, 1999) of cells, followed by inflammation and mitochondrial inhibition. The stimulation seems to be a
            direct "biophysical" action on cells, causing them to take up water (Minutoli, et al., 2008), which is
            especially interesting, since estrogen's immediate excitatory effect causes cells to take up water.
        </p>

        <p>
            Hypoosmolarity itself is excitatory and anabolic. It stimulates lipolysis and fat oxidation (Keller, et al.
            2003), and osmotic swelling stimulates glycolysis and inhibits mitochondrial respiration (Levko, et al.,
            2000). Endotoxin causes hyponatremia (Tyler, et al., 1994), and a hypertonic salt solution is protective,
            lactate solutions are harmful. Other stresses and inflammations also cause hyponatremia.
        </p>
        <p>
            One of the effects of endotoxin that leads to prolonged cellular excitation is its inhibition of the
            glucuronidation system (B"nhegyi, et al., 1995), since this inhibition allows excitatory estrogen to
            accumulate.
        </p>
        <p>
            In women and rats, antibiotics were found to cause blood levels of estrogen and cortisol to decrease, while
            progesterone increased. This effect apparently resulted from the liver's increased ability to inactivate
            estrogen and to maintain blood sugar when the endotoxin stress was decreased.
        </p>
        <p>
            Now that hog farmers' use of antibiotics to stimulate growth has been discouraged, they have sought
            vegetables that have a natural antibiotic effect, reducing the formation and absorption of the intestinal
            toxins. The human diet can be similarly adjusted, to minimize the production and absorption of the bacterial
            toxins.
        </p>
        <p>
            In 2007, two Canadian researchers announced that they were investigating the drug dichloroacetate, which
            blocks glycolysis, stopping the production of lactic acid, as a cancer treatment, with success. The drug
            (dichloroacetate) has toxic side effects, but it is useful in several other conditions involving
            over-production of lactic acid. Other drugs that inhibit glycolysis have also shown anticancer effects in
            animals, but are in themselves very toxic. On the theoretical level, it would be better to inhibit only
            aerobic glycolysis, rather than inhibiting enzymes that are essential for all glycolysis.
        </p>

        <p>
            Since endotoxemia can produce aerobic glycolysis in an otherwise healthy person (Bundgaard, et al., 2003), a
            minimally "Warburgian" approach--i.e,, a merely reasonable approach--would involve minimizing the absorption
            of endotoxin. Inhibiting bacterial growth, while optimizing intestinal resistance, would have no harmful
            side effects. Preventing excessive sympathetic nervous activity and maintaining the intestine's energy
            production can be achieved by optimizing hormones and nutrition. Something as simple as a grated carrot with
            salt and vinegar can produce major changes in bowel health, reducing endotoxin absorption, and restoring
            constructive hormonal functions.
        </p>
        <p>
            Medical tradition and inertia make it unlikely that the connection between cancer and bowel toxins will be
            recognized by the mainstream of medicine and governemt. In another article I will describe some of the
            recent history relating to this issue.
        </p>
        <p>
            It's nice that some cancer researchers are now remembering Warburg, but unfortunately they are usually just
            fitting the fact of cancer's aerobic glycolysis into the genetic mutant cell paradigm, thinking of the
            respiratory defect as just another opportunity for killing the evil deviant cancer cell, rather than looking
            for the causes of the respiratory defect. Warburg, Koch, and Szent-Gyorgyi had a comprehensive view of
            biology, in which the aerobic production of lactate, resulting from a respiratory defect, itself was
            functonally related to the nature of cancer.
        </p>
        <p>
            A focus on correcting the respiratory defect would be relevant for all of the diseases and conditions
            (including heart disease, diabetes, dementia) involving inflammation and inappropriate excitation, not just
            for cancer.

            Kawauchi K, Araki K, Tobiume K, Tanaka N. "Cancer cells use aerobic glycolysis preferentially for energy
            provision and this metabolic change is important for tumour growth. Here, we have found <strong>a link
                between the tumour suppressor p53, the transcription factor NF-kappaB and glycolysis."

                through suppression of glycolysis.</strong>
            These results suggest that a positive-feedback loop exists, whereby glycolysis drives IKK-NF-kappaB
            activation, and that hyperactivation of this loop by loss of p53 is important in oncogene-induced cell
            transformation."

            Leakiness, aging, and cancer
        </h1>

        A thin layer of fibrin lining blood vessels provides a filtering barrier that helps to strengthen the wall and
        prevent other proteins from leaking out of the vessels, and it participates in repair processes when the blood
        vessel is broken.<p>
            Cellular energy metabolism is the basis for maintaining the barrier functions. Energy depletion causes the
            endothelial cells lining blood vessels to become excessively permeable.
        </p>
        <p>
            When the organism's resistance is low, proteins and fats that normally remain inside the bloodstream can
            escape into the extracellular matrix and enter cells, contributing to their stress and disorganization, and
            other materials can escape from cells and enter the bloodstream.
        </p>
        <p>
            One of the simplest demonstrations of fibrin leakage is to shine a beam of light into the eye; the presence
            of fibrin and other inappropriate molecules diffuses the light, causing a "flare" in the aqueous
            compartment. Albumin, a small protein from the blood, is often seen in the urine during stress. The effects
            of that sort of leakage vary with each organ.
        </p>
        <p>
            Fibrin is an essential structural and functional part of the organism, but when it escapes from the
            bloodstream it participates in the degenerative processes of inflammation, fibrosis, and tumor formation.
            (Its fragments stimulate secretion of inflammatory mediators: Hamaguchi et al., 1991.)
        </p>
        <p>
            In the hormonal environment dominated by estrogen, mild stresses such as exertion, or even restless sleep,
            allow toxins (and sometimes bacteria) from the intestine to enter the bloodstream, triggering a complex
            chain of events that create a systemic inflammatory state. Although these processes have been observed in
            many simple experiments, their implications are almost always neglected or denied or explained away.
            Incorporation of certain polyunsaturated fats into the tissues increases the leakiness of blood vessels, and
            amplifies the reactions to stresses and inflammatory stimuli.
        </p>
        <p>
            Antioxidants, thyroid hormone, progesterone, and antiinflammatory agents, including glycine or gelatin,
            niacin, and saturated fats, can prevent, and in many cases reverse, these degenerative inflammatory
            processes.
        </p>
        <p>
            Even a single celled organism has to keep its parts separate, and highly differentiated multicelled
            organisms have many special systems that serve to keep their parts separate, so the different tissues and
            organs can maintain their distinct functions.
        </p>
        <p>
            The movement of substances from blood to cell, and from cell to cell, is normally very tightly controlled,
            and when the systems that control those movements of water and its solutes are damaged, the tissues'
            structures and functions are altered. The prevention of inappropriate leakiness can protect against the
            degenerative processes, and against aging itself, which is, among other things, a state of generalized
            leakiness.
        </p>
        <p>
            When cells' energy is depleted, water and various dissolved molecules are allowed to move into the cells,
            out of the cells, and through or around cells inappropriately. The weakened cells can even permit whole
            bacteria and similar particles to pass into and out of the blood stream more easily.
        </p>
        <p>
            One of the earliest investigators of the effects of stress and fatigue on nerves and other cells was A.P.
            Nasonov, in the first half of the 20th century. A.S. Troshin (1956) has reviewed his work in detail. He
            showed that in cells as different as algae and nerve cells, fatigue caused them to take up dyes, and that
            the dyes were extruded, if the cells were able to recover their energy. When nerve cells are excited for a
            fraction of a second, they take up sodium and calcium, but quickly eliminate them. Prolonged excitation,
            leading to fatigue, can gradually shift the balance, allowing more substances to enter, and to stay longer.
        </p>
        <p>
            When nerves or other cells are quickly killed with heavy metals such as osmium, the metals are visible in a
            layer at the surface, which is sometimes taken as evidence of a "cytoplasmic membrane," but if the cells
            have suffered oxygen deprivation or have been injured by X-rays, the metal will be visible as a grey color
            evenly distributed through the cell. The deposition of the metal occurs when it reacts with electrons. In
            the relatively vital cell, the heavy metal stops at the surface, and is mostly reduced there, but the
            devitalized cell presents no structural or chemical barrier to the entry of the metal, and the reactive
            electrons appear to be evenly distributed through the cell. Oxygen deprivation, X-irradiation, and other
            stresses cause the cell to be unable to use electrons to produce energy, and instead the electrons are
            available to react destructively with whatever may be available. While Nasonov showed that dyes and even
            particles enter energetically depleted cells, newer techniques are able to show that the leaky cells are
            structurally disrupted by the excessive reduction of their proteins, by excited electrons and free radicals.
        </p>
        <p>
            In the 1970s, experimenters found that muscles from vitamin E deficient animals released their enzymes when
            washed in a saline solution, more easily than did the muscles from vitamin E replete animals. Other
            experiments around the same time showed that reducing the ATP of muscles caused a similar loss of their
            ability to retain their proteins.
        </p>
        <p>
            Over the years, many experiments have established, both in vitro and in vivo, that fatigue, stress, aging,
            and inflammation cause cells to lose their normal constituents, but also to allow foreign materials to enter
            more easily.
        </p>
        <p>
            When I was working on my thesis, around 1970, investigating the effects of aging on the metabolism of the
            uterus, I found that the changes occuring during aging were (in all the ways I tested) the same as those
            produced by X-irradiation, excess estrogen, oxygen deprivation, excess polyunsaturated fats, and vitamin E
            deficiency.
        </p>
        <p>
            Although everyone working in the lab was familiar with the appearance of the uterus from old hamsters (they
            are typically large, stiff, and bluish), everyone was surprised when I suggested that the aged uteri seemed
            to function as if they were under the influence of a considerable amount of estrogen. Everyone was familiar
            with the medical textbook doctrine that "menopause is caused by estrogen deficiency." In humans,
            gynecologists know about "Chadwick's sign," the fact that the uterine cervix turns blue or purple during
            pregnancy, and everyone knows that blood is blue when it's deprived of oxygen, so it's surprising that
            estrogen's effect on tissue oxygenation isn't widely recognized.
        </p>
        <p>
            When estrogen is given to an animal, it almost instantly causes capillaries to become leaky, allowing water
            to move out of the blood stream, and at the same time, estrogen causes cells to take up water. Both of these
            processes are the same as the early effects of oxygen deprivation. In the normal reproductive cycle, the
            surge of estrogen lasts only a few hours, and normal permeability is quickly restored by increasing
            progesterone. During those intermittent short exposures to estrogen, there isn't a massive leakage of serum
            proteins into the tissues. During the time of estrogenic influence, all kinds of cells are influenced, with
            the excitatory equilibrium of nerve cells, glandular cells, and immune system cells being shifted, lowering
            the threshold of excitation, or prolonging the excited state.
        </p>
        <p>
            Anything that causes inflammation causes a similar loss of water from the blood, as it is taken up by
            swelling cells. If inflammation is generalized, it causes circulatory shock, because the volume of the blood
            has become insufficient to serve the organism's needs. One of Hans Selye's earliest observations of the
            effect of an overdose of estrogen was that it causes shock.
        </p>
        <p>
            Although water loss causes the blood to become more viscous under the influence of estrogen, the plasma
            becomes hypotonic, meaning that it contains fewer osmotically active solutes than normal; some of the sodium
            that helps to maintain the blood's osmotic balance is lost through the kidneys, and some is taken up by the
            red blood cells and other cells. The osmotic imbalance of the blood causes tissue cells to take up more
            water, contributing to their increased excitability. In many cases, the vascular leakage of inflammation and
            shock can be corrected by using osmotically active substances, such as starch solutions, gelatin, or
            concentrated sodium chloride.
        </p>
        <p>
            The tissue water retention caused by estrogen, hypoxia, and stress is analogous to the swelling of gels and
            colloids, that is, it's governed by the state of the electrons and counterions in the system. Excitation,
            fatigue, or injury can cause a shift of pH toward alkalinity, causing water uptake and swelling.
        </p>
        <p>
            The blue color of the pregnant cervix, or of the uterus in an animal given an overdose of estrogen,
            indicates that the tissue isn't sufficiently oxygenated to maintain its normal red color, even though the
            flow of blood is increased. Some experimenters have noticed that newborn animals sometimes have the postural
            reflex (lordosis) that indicates an estrogenic state, and that suffocation can produce the same reflex.
            Irradiating animals with x-rays will also produce the whole range of estrogenic effects.
        </p>
        <p>
            One of the features of the aged uterus that I studied was the age pigment, lipofuscin, a brown waxy material
            that accumulates in old or stressed tissues. Prolonged dosage with estrogen accelerates the formation of
            this pigment, which is largely derived from oxidized polyunsaturated fatty acids. Increased amounts of those
            fats in the diet, or a deficiency of vitamin E, or exposure to ionizing radiation, or oxygen deprivation,
            can also accelerate the formation of the age pigment. The presence of the pigment intensifies the effect of
            estrogen, since the pigment wastes oxygen by functioning as an oxidase enzyme.
        </p>
        <p>
            Other tests that I did on aged, or estrogenized, uterine tissue indicated that several oxidative systems
            were activated; for example, the tissues showed an extremely high activity of the enzyme peroxidase, and a
            very intense reduction of a chemical dye (tetrazolium/formazan) that indicates the presence of reductive and
            oxidative activity, of the sorts caused by radiation and oxygen deprivation. These reductive and oxidative
            processes include the production of some free radicals that are capable of reacting randomly with
            polyunsaturated fatty acids.
        </p>
        <p>
            The interactions between estrogen and the polyunsaturated fats are now coming to be more widely recognized
            as important factors in the inflammatory/hyperpermeable conditions that contribute to the development of
            heart and blood vessel disease, hypertension, cancer, autoimmune diseases, dementia, and other less common
            degenerative conditions.
        </p>
        <p>
            Estrogen increases lipid peroxidation, and maintains a chronically high circulating level of free fatty
            acids, mainly PUFA, activates the phospholipases that release arachidonic acid from cells leading to
            formation of prostaglandins and isoprostanes, and increases the enzymes that form the inflammation-promoting
            platelet activating factor (PAF) while suppressing the enzymes that destroy it, and increases a broad range
            of other inflammatory mediators, interleukins, and NF-kappa B.
        </p>
        <p>
            The leakage of enzymes out of cells and into the blood stream is recognized medically as evidence of damage
            to the organ that is losing them. Different combinations of enzymes are commonly considered to be evidence
            of a heart attack, or skeletal muscle damage, or liver disease, pancreatitis, prostate cancer, etc. But
            often the reason for the leakage isn't understood. Hypothyroidism, for example, causes leakage of enzymes,
            possibly mainly from the liver, but also from other organs. Excess estrogen, intense exercise, starvation,
            anything that increases lipid peroxidation and free radical production, such as drinking alcohol when the
            tissues contain polyunsaturated fats, can cause organs such as heart and liver to leak their components.
        </p>
        <p>
            The loss of enzymes increases the energy needed to stay alive, but it doesn't necessarily change the basic
            functions of the cell. (Though when mitochondrial enzymes leak out into the cytoplasm, the cell's energy
            metabolism is impaired, at least temporarily.) But the entry of catalytic materials from other tissues
            changes the organization of a cell, giving it conflicting instructions. In many situations, as L.V.
            Polezhaev and V. Filatov demonstrated, the substances released during stress and degeneration serve to
            stimulate healing and regeneration. But when the resources aren't available for full repair or regeneration,
            only a scar, or atrophic fibrosis, or a tumor will be formed.
        </p>
        <p>
            In severe stress, intracellular fibrin deposits have been found in the heart and other organs, including the
            prostate gland. Deficiency of testosterone causes vascular leakage into the prostate. Fibrin promotes tumor
            growth, partly by serving as a matrix, partly by releasing stimulatory peptides.
        </p>
        <p>
            Kidney disease, diabetes, pregnancy toxemia and retinal degeneration are probably the best known problems
            involving vascular leakage, but increasingly, cancer and heart disease are being recognized as consequences
            of prolonged permeability defects. Congestive heart failure and pulmonary hypertension commonly cause
            leakage of fluid into the lungs, and shock of any sort causes the lung to get "wet," a waterlogged condition
            called "shock lung." Simply hyperventilating for a couple of minutes will increase leakage from the blood
            into the lungs; hyperventilation decreases carbon dioxide, and increases serotonin and histamine. Hyperoxia
            itself contributes to lung injury, and exacerbates emphysema, though it is common to see patients breathing
            a high concentration of oxygen. Emphysema (which can be caused by hypothyroidism or hyper-estrogenism, and
            often can be cured by thyroid or progesterone) and many other respiratory problems are associated with
            capillary leakage. Cells of the lung and intestine are able to synthesize their own fibrin, apparently
            because of their special problems in preventing leakage. Prolonged systemic inflammation can lead to lung
            fibrosis, and fibrosis increases the likelihood of lung cancer.
        </p>
        <p>
            The inflammatory state that causes exaggerated cellular permeability is very closely related to
            "hyperventilation," the loss of too much carbon dioxide. The release of serotonin during hyperventilation
            isn't the only cause of vascular leakage; the carbon dioxide itself is an essential factor in regulating the
            state of cellular electrons and in maintaining cellular integrity. Hyperventilation, like the shift from
            oxidative to glycolytic energy production that typifies estrogenized or stressed cells or cancer, raises
            intracellular pH. In the case of mast cells, increasing alkalinity causes them to release histamine
            (Alfonso, et al., 2005), but similar "alkaline-induced exocytosis" seems to occur in all stressed tissues.
        </p>
        <p>
            The blood platelets that become incontinent and leak serotonin in the absence of carbon dioxide are
            undergoing the same structural stresses experience by endothelial cells, smooth muscle cells, mast cells and
            all other cells when carbon dioxide is depleted. Although it has been about 70 years since Yandell Henderson
            made it clear that supplemental oxygen should be combined with carbon dioxide, mechanical ventilation in
            hospitals is still causing lung injury resulting from hyperventilation, i.e., the absence of carbon dioxide.
            A similar misunderstanding of biology was involved in the use of dialysis to treat kidney disease. Until
            recently, commercial dialysis fluids contained acetate and/or racemic lactate instead of bicarbonate,
            because of the difficulty of preparing bicarbonate solutions, and the result was that very prolonged
            dialysis would damage the brain and other organs. (Veech and Gitomer, 1988, Veech and Fowler, 1987.)
            Dialysis has been seen to increase lung permeability Bell, et al., 1988).
        </p>
        <p>
            Amyloidosis produced by chronic dialysis affects all organs, but its effects are best known in the brain,
            heart, kidneys, and lungs. Serum amyloid-A is one of the acute phase proteins, like C-reactive protein
            (CRP), that are produced by inflammation. Estrogen, radiation and other stresses increase those
            pro-inflammatory acute phase proteins, and decrease protective albumin, which is called a "negative acute
            phase protein," since it decreases when the other acute phase proteins increase. The liver is the major
            source of the acute phase proteins, and it is constantly burdened by toxins absorbed from the bowel;
            disinfection of the bowel is known to accelerate recovery from stress.
        </p>
        <p>
            Seen from the perspective of the stress-leakage syndrome, any serious injury or sickness damages all organs.
            The exhaled breath is being used to diagnose inflammatory lung disease, since so many of the mediators of
            inflammation are volatile, but systemic diseases such as cancer and arthritis, and relatively minor stress
            can be detected by changes in the chemicals found in the breath. Polyunsaturated fats and their breakdown
            products--aldehydes, prostaglandins, isoprostanes, hydrocarbons, and free radicals--and carbon monoxide,
            nitric oxide, nitrite, and hydrogen peroxide are increased in the breath by most stresses. Both proline and
            glycine (which are major amino acids in gelatin) are very protective for the liver, increasing albumin, and
            stopping oxidative damage.
        </p>
        <p>
            Saturated fats are protective against free radical damage and can reverse liver fibrosis. Thyroid hormone
            protects against excess estrogen, and can prevent or reverse fibrosis of the heart. Antiestrogens are widely
            effective against vascular leakage. Thyroid, progesterone, and testosterone are among the most effective
            natural antiestrogens, and they are curative in many conditions that involve vascular leakage. Progesterone
            and pregnenolone have been called the antifibromatic steroids, and it has been used to treat many
            inflammatory and fibrotic diseases, including cancer.
        </p>
        <p>
            The antiserotonin drugs are being increasingly used to treat fibrotic diseases, and other problems related
            to vascular leakage.
        </p>
        <p>
            Antiinflammatory and anticoagulant things, especially aspirin and vitamin E, protect against the accelerated
            turnover of fibrinogen/fibrin caused by estrogen and the various inflammatory states.

            <strong>MULTIPLE SCLEROSIS AND OTHER HORMONE-RELATED BRAIN SYNDROMES (1993)</strong>

            Since I am trying to discuss a complex matter in a single article, I have separately outlined the essential
            technical points of the argument in a section at the beginning, then I explain how my ideas on the subject
            developed, and finally there is a glossary.&nbsp; If you start with "Short-day brain stress," "Estrogen's
            effects," and "Symptoms and therapies," you will have the general picture, and can use the other sections to
            fill in the technical details.
            <strong>&nbsp;</strong>
            <strong>THE ARGUMENT:&nbsp;</strong>&nbsp;&nbsp; 1) The hormones pregnenolone, thyroid, and estrogen are
            involved in several ways with the changes that occur in multiple sclerosis, but no one talks about them. 2)
            The process of myelination is known to depend on the thyroid hormone.&nbsp; The myelinating cells are the
            oligodendroglia (oligodendrocytes) which appear to stop functioning in MS (and&nbsp; sometimes to a milder
            degree in Alzheimer's disease, and other&nbsp; conditions).&nbsp; The cells' absorption of thyroid hormone
            is influenced by dietary factors. 3) The oligodendrocytes are steroid-producing cells (1),&nbsp; and
            steroidogenesis is dependent on thyroid hormone, and on&nbsp; thyroid-dependent respiratory enzymes and on
            the heme-enzyme P-450scc, which are all sensitive (2) to poisoning by carbon monoxide and cyanide.&nbsp; The
            steroid produced by the oligodendrocytes is pregnenolone, which is known to have a profound&nbsp;
            anti-stress action (3), and which appears to be the main&nbsp; brain-protective steroid. 4) Lesions
            resembling those of MS can be produced experimentally by carbon monoxide or cyanide poisoning.(4)&nbsp; The
            lesions&nbsp; tend to be associated with individual small blood vessels, which &nbsp; are likely to contain
            clots.&nbsp; (Since all animals have enzymes to&nbsp; detoxify cyanide, this poison is apparently a
            universal problem,&nbsp; and can originate in the bowel. "Detoxified" cyanide is still toxic to the
            thyroid.)&nbsp; 5) Pregnenolone and progesterone protect against nerve damage (5) by the excitotoxic amino
            acids (glutamic acid, aspartic acid, monosodium glutamate, aspartame, etc.), while estrogen (6) and cortisol
            (7) are nerve-destroying, acting through the excitotoxic amino acids.&nbsp; Excitotoxins destroy certain
            types of nerve, especially the dopaminergic and cholinergic types, leaving the noradrenergic types (8),
            paralleling the changes that occur in aging.&nbsp; The clustering of oligodendrocytes around deteriorating
            nerve cells could represent an adaptive attempt to provide pregnenolone to injured nerve cells. 6) The
            involvement of hormones and environmental factors probably accounts for the intermittent progress of
            multiple sclerosis. To the extent that the environmental factors can be&nbsp; corrected, the disease can
            probably be controlled.

            <strong>&nbsp;SHORT-DAY BRAIN STRESS</strong>
            Shortly after I moved from Mexico to Montana, one of my students, a 32 year old woman, began having the same
            sensory symptoms her older sister had experienced at the same age, at the onset of multiple sclerosis.&nbsp;
            Vertigo and visual distortions of some sort made her consider withdrawing from the university. I'm not sure
            why she tried eating a whole can of tuna for lunch a couple of days after the onset of symptoms, but it
            seemed to alleviate the symptoms, and she stayed on a high protein diet and never had a recurrence.&nbsp;
            She told me some of the lore of MS: That it mostly affects young adults between the ages of 20 and 40, that
            it is common in high latitudes and essentially unknown in the tropics, and that it is sometimes exacerbated
            by pregnancy and stress.&nbsp; (Later, I learned that systemic lupus erythematosis and other "auto-immune"
            diseases also tend to occur mainly during the reproductive years.&nbsp; I discussed some of the implications
            of this in "Bean Syndrome.") Having enjoyed the mild climate of Mexico, I became very conscious of the harm
            done to us by northern winters, and began developing the idea of "winter sickness."&nbsp; In 1966-67,
            allergies, PMS, weight gain, colitis, and arthritis came to my attention as winter-related problems, and I
            assumed that the high-latitude incidence of MS related to what I was seeing and experiencing.&nbsp; Studies
            in Leningrad began revealing that mitochondria are injured during darkness, and repaired during
            daylight.&nbsp; I observed that hamsters' thymus glands shrank in the winter and regenerated in the summer;
            shrinkage of the thymus gland is a classical feature of stress, and usually reflects the dominance of
            cortisone, though estrogen and testosterone also cause it to shrink.&nbsp; Winter's darkness is stressful in
            a very fundamental way, and like any stress it tends to suppress thyroid function.&nbsp; In the hypothyroid
            state, any estrogen which is produced tends to accumulate in the body, because of liver sluggishness. I
            began to see that PMS could be controlled by certain things--extra light, supplements of sodium and
            magnesium, high quality protein, and correction of deficiencies of thyroid and progesterone.&nbsp; In
            working on my dissertation, I saw that tissue hypoxia (lower than optimal concentrations of oxygen in the
            blood) may result from estrogen excess, vitamin E deficiency, or aging.&nbsp; There is a close biological
            parallel between estrogen-dominance and the other hypoxic states, such as stress/shock, and aging. &nbsp;
            <strong>ESTROGEN'S EFFECTS</strong>
            As a portrait painter, I had been very conscious of the blue aspect that can often be seen in the skin of
            young women. In pale areas, the color may actually be blue, and in areas with a rich supply of blood, such
            as the lips, the color is lavender during times of high estrogen influence--around ovulation and puberty,
            for example.&nbsp; During these times of estrogen dominance, the blood is not only poorly oxygenated, but it
            has other special properties, such as an increased tendency to clot.&nbsp; The Shutes' work in the 1930s
            began with the use of vitamin E to antagonize estrogen's clot-promoting tendency, and led them to the
            discovery that vitamin E can be very therapeutic in heart disease.&nbsp; More recently, it has been found
            that men with heart disease have abnormally high estrogen (9), that women using oral contraceptives have
            higher mortality from heart attacks (10), and that estrogen tends to&nbsp; promote spasm of blood vessels
            (11).&nbsp; (These reactions are probably&nbsp; related to the physiology of menstruation, in which
            progesterone&nbsp;withdrawal causes spasms in the spiral arteries of the uterus,&nbsp; producing endometrial
            anoxia and cell death.) In toxemia of late pregnancy, or eclampsia, the exaggerated clotting tendency caused
            by excess estrogen (or by inadequately opposed estrogen, i.e., progesterone deficiency), can cause
            convulsions and strokes.&nbsp; Vascular spasms could be involved here, too.&nbsp; The stasis caused by the
            vasospasm would facilitate clotting. (Vascular spasm has been observed in epilepsy, too.&nbsp; Epilepsy can
            be brought on by the premenstrual excess of estrogen, and in that situation there is no evidence that
            clotting is involved.&nbsp; Leakage of hemoglobin out of red cells can cause vasospasm, so bleeding,
            clotting, strokes, and seizures can interact complexly.)&nbsp; The brains of women who have
            died&nbsp;following eclampsia show massive clotting in the blood vessels, and their livers are
            characteristically injured, with clots (12). Tom Brewer and others have shown very clearly that
            malnutrition, especially protein deficiency, is the cause of toxemia of late pregnancy.&nbsp; (In Nutrition
            for Women, I discussed the importance of protein in allowing the liver to eliminate estrogen.) Various
            researchers have demonstrated that the plaques of MS usually occur in the area served by a single blood
            vessel (13, 14), and some have suggested that clotting is the cause.&nbsp; MS patients have been found to
            have an abnormal clotting time, and it has been suggested that an altered diet might be able to correct the
            clotting tendency. Studies in animals have shown clearly that a protein deficiency increases the fibrinogen
            content of blood. (Field and Dam, 1946.)&nbsp; Other factors that increase blood clotting are elevated
            adrenalin and cortisone.&nbsp; Protein deficiency causes an adaptive decrease in thyroid function, which
            leads to a compensatory increase in adrenaline and cortisone.&nbsp; The combination of high estrogen with
            high adrenaline increases the tendency for both clots and spasms of the blood vessels (11). In experimental
            poisoning of animals with carbon monoxide or cyanide, the brain lesions resembling MS include blood
            clots.&nbsp; The patchy distribution of these spots in the brain suggests that the clotting is secondary to
            metabolic damage in the brain.&nbsp; Presumably, the same would be true in ordinary MS, with clots and
            spasms being induced in certain areas by metabolic abnormalities in brain cells.&nbsp; The injured cells
            that are responsible for myelination of nerve fibers are steroid-forming cells.&nbsp; A failure to secrete
            their protective pregnenolone could cause a local spasm of a blood vessel.&nbsp; The circulatory problem
            would exacerbate the respiratory problem. Steroid production is dependent on NADH and NADPH, and so requires
            adequate energy supplies and energy metabolism.&nbsp; The phenomenon of blood-sludging, studied by M.
            Knisely at the University of Chicago in the l930s and l940s, is apparently a general result of decreased
            energy metabolism, and is likely to be a factor in energy-and-circulatory vicious circles.
            <strong>&nbsp;</strong>
            <strong>SYMPTOMS AND THERAPIES&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;</strong>
            Around 1976 I met a woman in her mid-thirties who heard about my work with progesterone in animals.&nbsp;
            She had been disabled by a brain disease that resembled MS or Devic's disease, inflammation of the optic
            nerves.&nbsp; It would sometimes cause blindness and paralysis that persisted for weeks at a time.&nbsp;
            During remissions, sometimes using a wheelchair, she would go to the medical school library to try to
            understand her condition.&nbsp; She came across Katherina Dalton's work with progesterone, and convinced a
            physician to give her a trial injection.&nbsp; Although she had trouble finding people who were willing to
            give her progesterone, her recovery was so complete that she was able to climb stairs and drive her car, and
            she came&nbsp; to my endocrinology class and gave a very good (and long) lecture on progesterone
            therapy.&nbsp; Although her sensory and motor functions became normal, she remained very fat, and
            chronically suffered from sore areas on her arms and legs that seemed to be abnormal blood vessels, possibly
            with phlebitis.&nbsp; She appeared to need thyroid hormone as well as larger amounts of progesterone, but
            never found a physician who would cooperate, as far as I know. In the late 1970s I was seeing a lot of
            people who had puzzling health problems.&nbsp; In a period of two or three years, there were five people who
            had been diagnosed by neurologists as having multiple sclerosis.&nbsp; In talking to them, it seemed clear
            that they had multiple symptoms of hypothyroidism. &nbsp; They weren't severely disabled.&nbsp; Since they
            weren't fat or lethargic, their physicians hadn't thought they could be hypothyroid.&nbsp; When they tried
            taking a thyroid supplement, all of their symptoms disappeared, including those that had led to their MS
            diagnosis.&nbsp; One of the women went to her doctor to tell him that she felt perfectly healthy since
            taking thyroid, and he told her to stop taking it, because people who have MS need a lot of rest, and she
            wouldn't get enough rest if she was living in a normally active way. The assumption seemed to be that the
            diagnosis was more important than the person. (When I refer to a "thyroid supplement" I mean one that
            contains some T3.&nbsp; Many people experience "neurological symptoms" when they take thyroxine by
            itself.&nbsp; Experimentally, it has been found to suppress brain respiration, probably by diluting the T3
            that was already present in the brain tissue.) &nbsp;
            <strong>&nbsp;</strong>
            <strong>METABOLISM OF THE OLIGODENDROCYTES</strong>
            The rate-regulating step in steroid synthesis involves the entry of cholesterol into the mitochondria, where
            the heme-enzyme P-450scc then removes the side-chain of cholesterol&nbsp; (by introducing oxygen atoms), to
            produce pregnenolone.&nbsp; This enzyme can be poisoned by carbon monoxide or cyanide, and light can
            eliminate the poison (15); this could be one aspect of the winter-sickness problem. &nbsp; Peripheral nerves
            are myelinated by essentially the same sort of cell that is called an oligodendrocyte in the brain, but
            outside the brain it is called a Schwann cell.&nbsp; It is easier to study the myelin sheath in peripheral
            nerves, and the electrical activity of a nerve is the most easily studied aspect of its physiology.&nbsp;
            Certain experiments seemed to indicate a "jumping" (saltatory) kind of conduction along the nerve between
            Schwann cells, and it was argued that the insulating function of the myelin sheath made this kind of
            conduction possible.&nbsp; This idea has become a standard item in physiology textbooks, and its familiarity
            leads many people to assume that the presence of myelin sheaths in the brain serves the same "insulating"
            function. For a long time it has been known that heat production during nerve conduction reveals a more
            continuous mode of&nbsp; conduction, that doesn't conform to the idea of an electrical&nbsp; current jumping
            around an insulator.&nbsp; Even if the myelin functioned primarily to produce "saltatory conduction" in
            peripheral nerves, it isn't clear how this process could function in the brain.&nbsp; I think of the issue
            of "saltatory conduction at the nodes of Ranvier" as another of the fetish ideas that have served to
            obstruct progress in biology in the United States.&nbsp; A more realistic approach to nerve function can be
            found in Gilbert Ling's work.&nbsp; Ling has demonstrated in many ways that the ruling dogma of "cell
            membrane" function isn't coherently based on fact.&nbsp; He found that hormones such as progesterone
            regulate the energetic and structural stability of cells.&nbsp; Many people, unaware of his work, have felt
            that it was necessary to argue against the idea that there are anesthetic steroids with generalized
            protective functions, because of their commitment to a textbook dogma of "cell membrane" physiology. I think
            the myelinating cells do have relevance to nerve conduction, but I don't think they serve primarily as
            electrical insulators.&nbsp; If the adrenal cortex were inside the heart, it would be obvious to ask whether
            its hormones aren't important for the heart's function.&nbsp; Since the oligodendrocytes are
            steroid-synthesizers, it seems obvious to ask whether their production of pregnenolone in response to stress
            or fatigue isn't relevant to the conduction processes of the nerves they surround.&nbsp; &nbsp; &nbsp;
            &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;
            <strong>&nbsp;</strong>
            <strong>OLD AGE</strong>
            A biologist friend of mine who was about 85 became very senile.&nbsp; His wife started giving him thyroid,
            progesterone, DHEA and pregnenolone, and within a few days his mental clarity had returned.&nbsp; He
            continued to be mentally active until he was 89, when his wife interfered with his access to the hormones.
            In old age the brain steroids fall to about 5% of their level in youth.&nbsp; Pregnenolone and DHEA improve
            memory in old rats, and improve mood stability and mental clarity of old people.&nbsp; Pregnenolone's action
            in improving the sense of being able to cope with challenges probably reflects a quieting and coordinating
            of the "sequencing" apparatus of the forebrain, which is the area most sensitive to energy
            deprivation.&nbsp; This is the area that malfunctions in hyperactive and "dyslexic" children.&nbsp;
            Weakening of the sequencing and sorting processes probably explains the common old-age inability to extract
            important sounds from environmental noise, creating a kind of "confusion deafness."&nbsp; Insomnia, worry
            and "restless legs" at bedtime are problems for many old people, and I think they are variations of the
            basic energy-depletion problem. The oligodendrocytes were reported (Hiroisi and Lee, 1936) to be the source
            of the senile plaques or amyloid deposits of Alzheimer's disease.(16)&nbsp; Hiroisi and Lee showed the cells
            in different stages of degeneration, ending with translucent "mucoid" spots that stained the same as
            amyloid, the material in the senile plaques.&nbsp; This type of cell also appears to form a halo or crown
            around degenerating nerve cells--possibly in a protective reaction to provide the nerve cell&nbsp; with any
            pregnenolone the oligodendrocytes are able to make.&nbsp; The&nbsp; oligodendrocytes, the source of the
            brain steroids (that people previously believed came from the adrenals and gonads, and were just stored in
            the brain), myelinate nerve fibers under the&nbsp; influence of thyroid hormone (17).&nbsp; Thyroid is
            responsible for both myelination and hormone formation.&nbsp; In old age, glial cells become more numerous,
            and nerve cells become structurally&nbsp; and functionally abnormal, but usually there is no problem&nbsp;
            with the formation of myelin.&nbsp; In MS, the problem is just with&nbsp; myelination, and there are no
            senile plaques or defects in the&nbsp; nerve cells themselves. &nbsp; &nbsp;&nbsp; &nbsp; These differences
            suggest the possibility that Alzheimer's&nbsp; disease involves a specific premature loss of brain
            pregnen-&nbsp; olone production, but not of thyroid.&nbsp; Recent work suggests a central role for
            pregnenolone and progesterone in the regulation of consciousness (18), and possibly in the brain's
            detoxifying system.&nbsp; Elsewhere, I have suggested that vitamin A deficiency might cause the excessive
            production of the "amyloid" protein.&nbsp; A vitamin A deficiency severely inhibits steroid synthesis.&nbsp;
            (It is used so massively in steroid synthesis that a progesterone supplement can prevent the symptoms of
            vitamin A deficiency.)&nbsp; I suspect that vitamin A is necessary for the side-chain cleavage that converts
            cholesterol to pregnenolone.&nbsp; Iron-stimulated lipid peroxidation is known to block steroid formation,
            and vitamin A is very susceptible to destruction&nbsp; by iron and oxidation.&nbsp; Iron tends to
            accumulated in tissues&nbsp; with aging.&nbsp; Gajdusek has demonstrated that brain deterioration&nbsp; is
            associated with the retention of whatever metal happens to be abundant in the person's environment, not just
            with aluminum.&nbsp; (One type of glial cell is known for its metal-binding function, causing them to be
            called "metallophils.").&nbsp; According to Gajdusek, "calcium and other di- and trivalent elements" are
            "deposited as hydroxyapatites in brain cells" in brain degeneration of the Alzheimer's type.(19) Even early
            forms of Alzheimer's disease begin at an age&nbsp; when the youth-associated steroids have begun to decline.
            If&nbsp; MS involves a deficiency of thyroid (or of T3 within the oligodendrocytes, where T3 normally can be
            made from thyroxine; many things, including protein deficiency, can block the conversion of T4 to T3), those
            cells would necessarily be deficient in their ability to produce pregenolone, but in&nbsp; young people the
            brain would still be receiving a little pregnenolone, progesterone, and DHEA from the adrenals and
            gonads.&nbsp; This relatively abundant youthful supply of hormones would keep most of the body's organs in
            good condition,&nbsp; and could keep the bodies of the major brain cells from deteriorating. But if proper
            functioning of the nerve fibers requires that they be fed a relatively high concentration of pregnenolone
            from their immediately adjacent neighbors (with the amount increasing during stress and fatigue), then their
            function would be impaired when they had to depend on the hormones that arrived from the blood stream. For
            many years it has been recognized that the brain atrophy of "Alzheimer's disease" resembles the changes seen
            in the brain in many other situations:&nbsp; The traumatic dementia of boxers; toxic dementia; the
            slow-virus diseases; exposure of the brain to x-<span class="il">rays</span>&nbsp;(20); ordinary old age;
            and in people with Down's syndrome who die around the age of thirty.&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;
            &nbsp; In menopause, certain nerve cells have lost their ability to regulate the ovaries, because of
            prolonged exposure to estrogen (6).&nbsp; The cells that fail as a result of prolonged estrogen exposure
            aren't the same cells that fail from prolonged exposure to the glucocorticoids (7), but they have in common
            the factor of excitatory injury. Since people who experience premature menopause are known to be more likely
            than average to die prematurely, it is reasonable to view menopause as a model of the aging process. It is
            now well established that progesterone fails to be produced at the onset of menopause (the first missed
            period, increased loss of calcium, symptoms such as hot flashes, etc.), and that estrogen continues to be
            produced at monthly intervals for about four years.&nbsp; The essential question for aging, in the present
            context, is why the anesthetic steroids are no longer produced at a rate that allows them to protect
            tissues, including brain cells, from the excitotoxins.&nbsp; Using menopause as a model for aging, we can
            make the question more answerable by asking why progesterone stops being produced. During stress, we are
            designed not to get pregnant, and the simplest aspect of this is that ACTH, besides stimulating the adrenals
            to produce stress-related hormones, inhibits the production of progesterone by the ovary.&nbsp; Other
            stress-induced factors, such as increased prolactin and decreased thyroid, also inhibit progesterone
            production.&nbsp; Stress eventually makes us more susceptible to stress.&nbsp; Menopause and other landmarks
            of aging simply represent upward inflections in the rate-of-aging curve.&nbsp; Individual variations in type
            of stress, hormonal response and diet, etc., probably govern the nature of the aging process in an
            individual. The amphetamine-like action of estrogen, which undoubtedly&nbsp; contributes to the general
            level of stress and excitotoxic&nbsp; abuse of nerve cells, is probably the only "useful" facet of&nbsp;
            estrogen treatment, but a little cocaine might achieve the&nbsp; same effect with no more harm, possibly
            less.&nbsp; The toxicity of catecholamines has been known for over thirty years, and estrogen's stimulating
            effects are partly the result of its conversion to catechol-estrogens which increase the activity of brain
            catecholamines.&nbsp; Estrogen's powerful ability to nullify learning seems never to be mentioned by the
            people who promote its use.&nbsp; The importance of a good balance of brain steroids for mood, attention,
            memory, and reasoning is starting to be recognized, but powerful economic forces militate against its
            general acceptance. Since the brain is the organ that can allow us to adapt without undergoing stress in the
            hormonal sense, it is very important to protect its flexibility and to keep its energy level high, so it can
            work in a relaxed way.&nbsp; It is the low energy cellular state that leads to the retention of calcium and
            iron, and to the production of age pigment, and other changes that constitute the vicious circle of
            aging.&nbsp; And mental activity that challenges obsession and rigidity might be the most important brain
            energizer.&nbsp; Pseudo-optimism, humor-as-therapy, has a certain value, but a deeper optimism involves a
            willingness to assimilate new information and to change plans accordingly.

            <strong>SUPPLEMENTS</strong>
            Nutritional supplements that might help to prevent or correct these brain syndromes include: Vitamin E
            and&nbsp; coconut oil; vitamin A; magnesium, sodium; thyroid which&nbsp; includes T3; large amounts of
            animal protein, especially&nbsp; eggs; sulfur, such as magnesium sulfate or flowers of&nbsp; sulfur, but not
            to take continuously, because of sulfur's interference with copper absorption; pregnenolone; progesterone if
            needed.&nbsp; Bright light, weak in the blue end of the spectrum and with protection against ultraviolet,
            activates respiratory metabolism and quenches free radicals.&nbsp; Raw carrot fiber and/or laxatives if
            needed; charcoal occasionally for gas or bowel&nbsp; irritation.&nbsp; Coconut oil serves several
            purposes.&nbsp; Its butyric acid is known to increase T3 uptake by glial cells.&nbsp; It has a general
            pro-thyroid action, for example by diluting and displacing antithyroid unsaturated oils, its short- and
            medium-chain fatty acids sustain blood sugar and have antiallergic actions, and it protects mitochondria
            against stressinjury.&nbsp; P.S.:&nbsp; In 1979, a woman whose husband was suffering from advanced
            Amyotrophic Lateral Sclerosis (ALS) asked me if I had any ideas for slowing his decline.&nbsp; I described
            my suspicion that ALS involved defective metabolism or regulation of testosterone.&nbsp; In some tissues,
            testosterone is selectively concentrated to prevent atrophy, and ALS is a disease of middle-age, when
            hormone regulation often becomes a special problem.&nbsp; In the late 1970s, there was discussion of a
            higher incidence of ALS in males, and especially in athletes.&nbsp; I told her about progesterone's general
            protective effects, its antagonism to testosterone, and its prevention of atrophy in various tissues.&nbsp;
            She decided to ask her doctor to try progesterone for her husband.&nbsp; Later, I learned that her husband
            had gone into a very rapid decline immediately after the injection, and died within a week; the physician
            had given him testosterone, since, he said, "testosterone and progesterone are both male hormones."&nbsp;
            Besides making me more aware of the problems patients have in communicating with physicians, this tended to
            reinforce my feeling that a hormone imbalance is involved in ALS.&nbsp; Although I haven't written much
            about testosterone's toxicity, Marian Diamond's work showed that prenatal testosterone is similar to
            prenatal estrogen, in causing decreased thickness of the cortex of the brain; both of those hormones oppose
            progesterone's brain-protecting and brain-promoting actions.

            GLOSSARY&nbsp;&nbsp; 1.&nbsp; Amyloid is the old term for the "starchy" appearing (including the way it
            stains) proteins seen in various diseases, and in the brain in Alzheimer's disease. 2.&nbsp; Cytochrome
            P450scc.&nbsp; The cytochromes are "pigments," in the same sense that they contain the colored "heme" group
            that gives hemoglobin its color.&nbsp; P450 means "protein that absorbs light at a wavelength of 450.&nbsp;
            The scc means "side-chain cleaving," which refers to the removal of the 6 carbon atoms that distinguish
            cholesterol from pregnenolone. Other Cyt P450 enzymes are important for their detoxifying oxidizing action,
            and some of these are involved in brain metabolism. 3.&nbsp; Glial means "glue-like," and glial cells are
            mostly spidery-shaped cells that used to be thought of as just connective, supportive cells in the brain.
            4.&nbsp; Mitochondria (the "thread-like bodies") are the structures in cells which produce most of our
            metabolic energy by respiration, in response to the thyroid hormones. 5.&nbsp; Mucoid--refers to a
            mucoprotein, a protein which contains some carbohydrate.&nbsp; A glycoprotein; usually not intended as a
            precise term. 6.&nbsp; Myelination.&nbsp; Myelin is a multilayered enclosure of the axons (the long
            processes) of nerve cells, composed of proteins and complex lipids, including cholesterol.&nbsp; The layered
            material is a flat, thin extension of the cytoplasm of the oligodendroglial cells. 7.&nbsp; Oligodendrocytes
            are one of the kinds of glial (or neuroglial) cells, and structurally they are unusual in having sheet-like,
            rather than just thread-like processes; they have a sensitivity ("receptors") to stress and valium, and
            produce pregnenolone when activated.&nbsp; Under the influence of thyroid hormone, they wrap themselves in
            thin layers around the conductive parts of nerve cells, leaving a multilayered "myelin" coating.&nbsp; Their
            absorption of thyroid hormone is promoted by butyrate, an anti-stress substance found in butter and coconut
            oil. 8.&nbsp; Steroidogenesis is the creation of steroids, usually referring to the conversion of
            cholesterol to hormones.

                        multiple sclerosis.&nbsp; Vertigo and visual distortions of some sort made her consider

                        stayed on a high protein diet and never had a recurrence.&nbsp; She told me some of the lore of
                        MS: That it mostly affects young adults between the ages of 20 and 40, that it is common in high
                        latitudes and essentially unknown in the tropics, and that it is sometimes exacerbated by

                        darkness, and repaired during daylight.&nbsp; I observed that hamsters' thymus glands shrank in
                        the winter and regenerated in the summer; shrinkage of the thymus gland is a classical feature
                        of stress, and usually reflects the dominance of cortisone, though estrogen and testosterone
                        also cause it to shrink.&nbsp; Winter's darkness is stressful in a very fundamental way, and
                        like any stress it tends to suppress thyroid function.&nbsp; In the hypothyroid state, any
                        estrogen which is produced tends to accumulate in the body, because of liver sluggishness.</span

                        supply of blood, such as the lips, the color is lavender during times of high estrogen
                        influence--around ovulation and puberty, for example.&nbsp; During these times of estrogen
                        dominance, the blood is not only poorly oxygenated, but it has other special properties, such as
                        an increased tendency to clot.&nbsp; The Shutes' work in the 1930s began with the use of vitamin
                        E to antagonize estrogen's clot-promoting tendency, and led them to the discovery that vitamin E
                        can be very therapeutic in heart disease.&nbsp; More recently, it has been found that men with

                        multiple sclerosis.&nbsp; In talking to them, it seemed clear that they had multiple symptoms of

                        perfectly healthy since taking thyroid, and he told her to stop taking it, because people who
                        have MS need a lot of rest, and she wouldn't get enough rest if she was living in a normally
                        active way. The assumption seemed to be that the diagnosis was more important than the person.

                        is the most easily studied aspect of its physiology.&nbsp; Certain experiments seemed to
                        indicate a "jumping" (saltatory) kind of conduction along the nerve between Schwann cells, and
                        it was argued that the insulating function of the myelin sheath made this kind of conduction
                        possible.&nbsp; This idea has become a standard item in physiology textbooks, and its
                        familiarity leads many people to assume that the presence of myelin sheaths in the brain serves
                        the same "insulating" function.</span></span></span>

                        this tended to reinforce my feeling that a hormone imbalance is involved in ALS.&nbsp; Although
                        I haven't written much about testosterone's toxicity, Marian Diamond's work showed that prenatal
                        testosterone is similar to prenatal estrogen, in causing decreased thickness of the cortex of
                        the brain; both of those hormones oppose progesterone's brain-protecting and brain-promoting
                        actions.</span></span></span>

            Natural Estrogens
        </h1>

        <p>
            The fact that an extremely large number of naturally occurring compounds, and an unlimited number of
            synthetic compounds, have an estrogen-like activity has been exploited by the drug companies to produce
            patented proprietary drugs, especially the contraceptives.
        </p>
        <p>
            The promotion of "natural estrogens" is a new marketing strategy that capitalizes on the immense promotional
            investment of the drug companies in the concept of estrogen replacement as "therapy."
        </p>

            <strong>"Whether weak or strong, the estrogenic response of a chemical, if not overcome, will add extra
                estrogenic burden to the system. At elevated doses, natural estrogens and environmental estrogen-like
                chemicals are known to produce adverse effects. The source of extra or elevated concentration of
                estrogen could be either endogenous or exogenous.</strong> The potential of exposure for humans and
            animals to environmental estrogen-like chemicals is high."

        <p>
            Estrogen marketing has entered a new phase, based on the idea of "specific estrogen-receptor modulators,"
            the idea that a molecule can be designed which has estrogen's "good qualities without its bad qualities."
            This specific molecule will be "good for the bones, the heart, and the brain," without causing cancer of the
            breast and uterus, according to the estrogen industry. Meanwhile, soybeans are said to contain estrogens
            that meet that goal, and it is often said that "natural estrogens" are better than "synthetic estrogens"
            because they are "balanced."
        </p>
        <p>
            Estrogen's effects on cells are immediate and profound, independent of the "estrogen receptors."
        </p>

        <p>
            Japanese women's relative freedom from breast cancer is independent of soy products<strong>:</strong>
            traditional soy foods aren't the same as those so widely used in the US, for example, soy sauce doesn't
            contain the so-called soy estrogens, and tea is used much more commonly in Japan than in the US, and
            contains health protective ingredients. The "estrogenic" and "antioxidant" polyphenolic compounds of tea are
            not the protective agents (they raise the level of estrogen), but tea's <em>caffeine</em> is a very powerful
            and general anti-cancer protectant. The influential article in <em>
                Lancet</em> (D. Ingram, <em>Lancet</em> 1997;<em>350</em>:990-994. "Phytoestrogens and their role in
            breast cancer,"<em>
                Breast NEWS: Newsletter of the NHMRC National Breast Cancer Centre, Vol. 3,</em> No. 2, Winter 1997)
            used a method known to produce false results, namely, comparing the phytoestrogens (found in large amounts
            in soybeans) in the urine of women with or without breast cancer. For over fifty years, it has been known
            that the liver excretes estrogens and other toxins from the body, and that when (because of liver inertia)
            estrogen isn't excreted by the liver and kidneys, it is retained in the body. This process was observed in
            both animals and humans decades ago, and it is <em>also well established that estrogen itself suppresses the
                detoxifying systems, causing fewer carcinogens to be excreted</em> in the urine. Ingram's evidence
            logically would suggest that the women who have cancer are failing to eliminate estrogens, including
            phytoestrogens, at a normal rate, and so are retaining a higher percentage of the chemicals consumed in
            their diets. Flavonoids and polyphenols, like our own estrogens, suppress the detoxifying systems of the
            body.
        </p>

        <p>
            Our bodies produce estrogen in a great variety of tissues, not just in the ovaries. Fat cells are a major
            source of it. The tendency to gain weight after puberty is one of the reasons that women's estrogen levels
            rise with aging throughout the reproductive years, though this isn't the basic reason for estrogen's
            lifelong growing influence, even in men.
        </p>
        <p>
            Our diets provide very significant, if not always dangerous, amounts of estrogen. "Weak estrogens" generally
            have the full range of harmful estrogenic effects, and often have additional toxic effects. American women
            who eat soy products undergo changes that appear to predispose them to cancer, making their tissues even
            more unlike those of the relatively breast-cancer resistant Japanese than they were before eating the soy
            foods.
        </p>
        <p>
            People under stress, or who have a thyroid deficiency, or who don't eat enough protein, typically have
            elevated estrogen levels. The accumulation of the "essential fatty acids," the polyunsaturated oils, in the
            tissues promotes the action of estrogen in a variety of ways, and this effect of diet tends to be
            cumulative, and to be self-accelerating.
        </p>

        <p>
            Science is a method that helps us to avoid believing things that are wrong, but there is a distinct herd
            instinct among people who "work in science," which makes it easy to believe whatever sounds plausible, if a
            lot of other people are saying it is true. This is just as evident in physics as it is in medicine.
            Sometimes powerful economic interests help people to change their beliefs, for example as the insurance
            industry helped to convince the public of the dangers of smoking. Two of the biggest industries in the
            world, the estrogen industry and the soy bean industry, spend vast amounts of money helping people to
            believe certain plausible-sounding things that help them sell their products. Sometimes they can achieve
            great things just by naming the substance.
        </p>
        <p>
            Estrogenicity can be defined most simply as "acting the way estrogen does," (originally, the term "estrogen"
            meant "producing estrus," the female readiness to mate) and since our natural estrogen does many things, the
            definition is often, for practicality, based on the rapid changes produced in certain female organs by
            estradiol, specifically, the enlargement of the uterus by first taking up a large amount of water, and
            secondarily by the multiplication of cells and the production of specific proteins. A similar process
            occurring in the breast is also recognized as an important feature of the estrogen reaction, but as we try
            to define just what "estrogenicity" is, we see that there is something deeply wrong with this method of
            defining a hormone, because we are constantly learning more about the actions of estrogen, or of a specific
            form of the molecule. Calling it "the female hormone" distracted attention from its many functions in the
            male, and led to great confusion about its antifertility actions and its other toxicities. Many biologists
            called it "folliculin," because of the ovarian follicle's significant role in its production, but the
            pharmaceutical industry succeeded in naming it in relation to <strong><em>
                    one</em></strong> of its functions, and then in extending that idea of it as "the producer of female
            receptivity" to the even more misleading idea that it is "the female hormone." But when people speak about
            the "estrogenicity" of a substance, they mean that it has properties that parallel those of "folliculin,"
            the particular group of ovarian hormones that includes estradiol, estrone, and estriol.

            Over the last 100 years, thousands of publications about estrogen's toxicity have created a slight
            resistance to the consumption of the major estrogen products. One ploy to overcoming this resistance is to
            call certain products "natural estrogen," as distinguished from "synthetic estrogens." The <strong
            >three</strong>
            <strong>main estrogens in our bodies are estradiol, estrone, and estriol, though there are many other minor
                variants on the basic molecule.</strong> These three estrogens, singly or in combinations, are being
            sold as natural estrogens, with their virtues explained in various ways. Implicit in many of these
            explanations, is the idea that these are safer than synthetics. They are sometimes contrasted to the "horse
            estrogen" in Premarin, as if they are better because they are like the estrogens that people produce. But it
            was exactly the normal human estrogens, produced by the ovaries, that led to the basic discoveries about the
            toxicity of estrogen, its ability to produce cancer in any organ, to cause seizures, blood clots, birth
            defects, accelerated aging, etc.
        </p>

        <p>
            Although I would suppose that a hormone from a horse might be "more natural" for a person's body than a
            hormone from a plant, the word "natural" as used in the phrases "natural food store," or "natural medicine,"
            has come to be associated strongly with things derived from plants. The health food industry, now largely
            taken over by giant corporations to sell products that weren't producing as much revenue when sold in
            supermarkets and drugstores, has helped to create a culture in which botanical products are thought to be
            especially good and safe. Naturally grown free-range chickens used to be favored, because they could eat
            anything they wanted, but now eggs laid by factory chickens, eating an industrial corn-and-soy diet, are
            from "vegetarian chickens," because the marketers know the public will favor eggs that have the vegetarian
            mystique.

            Biologically active molecules have both general and specific properties. Estrogenicity is a general
            property, but all molecules which have that property also have some other specific properties. Estriol is a
            little more water soluble than estrone, so it interacts with every body system in a slightly different way,
            entering oily environments with slightly less ease, etc.
        </p>
        <p>
            The estrogen which occurs in yeasts, estradiol, is identical to the major human estrogen, and it is thought
            to have a reproductive function in yeasts, though this isn't really understood. A feature of this molecule,
            and of all other molecules that "act like estrogen," is the phenolic function, an oxygen and hydrogen group
            attached to a resonant benzene ring. Phenol itself is estrogenic, and the phenolic group is so extremely
            common in nature that the number of existing estrogenic substances is great, and the number of potential
            molecules with estrogen-function is practically infinite.
        </p>
        <p>
            The phenolic group has many biological functions. For example, it commonly functions as an "antioxidant,"
            though something which functions as an antioxidant in one situation is often a pro-oxidant in another
            situation. The molecule can have catalytic, germicidal, aromatic, neurotropic, and other functions. But it
            also always has, to some degree, the "estrogenic" function. This overlap of functions probably accounts for
            why so many plants have significant estrogenic activity. (Natural estrogens, like other phenolics, including
            the flavonoids, are also mutagenic.)

        <p>
            The estrogenic properties of legumes were studied when sheep farmers found that their sheep miscarried when
            they ate clover. (I think it's interesting how this terribly toxic effect has been neglected in recent
            decades.) All legumes have this property, and all parts of the plant seem to contain some of the active
            chemicals. In beans, several substances have been found to contribute to the effect. The estrogenic effects
            of the seed oils and the isoflavones have been studied the most, but the well-known antithyroid actions
            (again, involving the oils, the isoflavones, and other molecules found in legumes) have an indirect
            estrogen-promoting action, since hypothyroidism leads to hyperestrogenism. (Estrogens are known to be
            thyroid suppressors, so the problem tends to be self-accelerating.)
        </p>
        <p>
            The various specific actions of the many estrogenic substances in beans and other legumes haven't been
            throughly studied, but there is evidence that they are also--like estrogen itself--both mutagenic and
            carcinogenic.
        </p>
        <p>
            The estrogen-promoting actions of soy oil apply to <strong>all of the commonly used polyunsaturated fatty
                acids. The same fatty acids that suppress thyroid function, have estrogenic effects.</strong>
        </p>

        <p>
            The isoflavones (many of which are now being promoted as "antioxidants" and "cancer preventives") are toxic
            to many organs, but they have clear estrogenic effects, and are active not only immediately in the mature
            individual, but when they are present prenatally, they cause feminization of the male genitalia and
            behavior, and early maturation of the female offspring, with the tissue changes that are known to be
            associated with increased incidence of cancer.

            There are interesting associations between vegetable "fiber" and estrogens. Because of my own experience in
            finding that eating a raw carrot daily prevented my migraines, I began to suspect that the carrot fiber was
            having both a bowel-protective and an antiestrogen effect. Several women who suffered from premenstrual
            symptoms, including migraine, had their serum estrogen measured before and after the "carrot diet," and they
            found that the carrot lowered their estrogen within a few days, as it relieved their symptoms.
        </p>
        <p>
            Undigestible fiber, if it isn't broken down by bowel bacteria, increases fecal bulk, and tends to speed the
            transit of material through the intestine, just as laxatives do. But some of these "fiber" materials, e.g.,
            lignin, are themselves estrogenic, and other fibers, by promoting bacterial growth, can promote the
            conversion of harmless substances into toxins and carcinogens. When there is a clear "antiestrogen" effect
            from dietary fiber, it seems to be the result of accelerated transit through the intestine, speeding
            elimination and preventing reabsorption of the estrogen which has been excreted in the bile. Laxatives have
            this same effect on the excretion of estradiol.
        </p>
        <p>
            Some of the isoflavones, lignins, and other phytoestrogens are said to prevent bowel cancer, but some of
            them, e.g., lignin, appear to sometimes increase its likelihood.
        </p>

        <p>
            The phytoestrogens appear to pose a risk to organs besides the breast and uterus, for example the liver,
            colon, and pancreas, which isn't surprising, since estrogen is known to be carcinogenic for every tissue.
            And carcinogenesis, like precancerous changes, mutations, and reduced repair of DNA, is probably just an
            incidental process in the more general toxic effect of acceleration of aging.

            protective effects against premenopausal breast cancer in Asian women. No studies have been reported on
            potential physiological effects of dietary soy consumption on breast gland function. We evaluated the
            influence of the long-term ingestion of a commercial soy protein isolate on breast secretory activity. We
            hypothesized that the features of nipple aspirate fluid (NAF) of non-Asian women would be altered so as to
            resemble those previously found in Asian women. At monthly intervals for 1 year, 24 normal pre- and
            postmenopausal white women, ages 30 to 58, underwent nipple aspiration of breast fluid and gave blood and
            24-h urine samples for biochemical studies. No soy was administered in months 1-3 and 10-12. Between months
            4-9 the women ingested daily 38 g of soy protein isolate containing 38 mg of genistein. NAF volume, <strong
            >gross cystic disease fluid protein (GCDFP-15) concentration</strong>, and NAF cytology were used as
            biomarkers of possible effects of soy protein isolate on the breast. In addition, plasma concentrations of
            estradiol, progesterone, sex hormone binding globulin, prolactin, cholesterol, high density
            lipoprotein-cholesterol, and triglycerides were measured. Compliance was assessed by measurements of
            genistein and daidzein and their metabolites in 24-h urine samples. Excellent compliance with the study
            protocol was obtained. Compared with NAF volumes obtained in months 1-3, <strong>a 2-6-fold increase in NAF
                volume ensued during months 4-9 in all premenopausal women.</strong> A minimal increase or no response
            was found in postmenopausal women. No changes were found in plasma prolactin, sex hormone binding globulin,
            cholesterol, high density lipoprotein cholesterol, and triglyceride concentrations. Compared with
            concentrations found in months 1-3 (no soy), <strong>plasma estradiol concentrations were elevated

            a "composite" menstrual cycle during the months of soy consumption. No significant changes were seen in
            plasma progesterone concentrations. No significant changes were found in plasma estrogen levels in
            postmenopausal women. A moderate decrease occurred in the mean concentration of GCDFP-15 in NAF in
            premenopausal women<u> during the months of soy ingestion. </u>
            <strong><u>Of potential concern was the cytological detection of epithelial hyperplasia in 7 of 24 women

                    a priori hypothesis. Instead, this pilot study indicates that prolonged consumption of soy protein
                    isolate has a stimulatory effect on the premenopausal female breast, characterized by increased
                    secretion of breast fluid, the appearance of hyperplastic epithelial cells,</u> and elevated levels

            W405, Georgetown University, 3970 Reservoir Road, NW, Washington, DC, 20007-2197, USA. <strong>Human and
                animal data indicate that a high maternal estrogen exposure during pregnancy increases breast cancer
                risk among daughters. This may reflect an increase in the epithelial structures</strong> that are the
            sites for malignant transformation, i.e., terminal end buds (TEBs), and a reduction in epithelial
            differentiation in the mammary gland. Some <strong>phytoestrogens, such as genistein which is a major
                component in soy-based foods, and zearalenone, a mycotoxin found in agricultural products, have
                estrogenic effects on the reproductive system, breast and brain.
            </strong>The present study examined whether in utero exposure to genistein or zearalenone influences mammary
            gland development. Pregnant mice were injected daily with i) 20 ng estradiol (E2); ii) 20 microg genistein;
            iii) 2 microg zearalenone; iv) 2 microg tamoxifen (TAM), a partial estrogen receptor agonist; or v)
            oil-vehicle between days 15 and 20 of gestation. E2, <strong>genistein, zearalenone, and tamoxifen all
                increased the density of TEBs in the mammary glands. Genistein reduced, and zearalenone increased,
                epithelial differentiation.</strong> Zearalenone also increased epithelial density, when compared with
            the vehicle-controls. None of the treatments had permanent effects on circulating E2 levels. <strong>
                Maternal exposure to E2 accelerated body weight gain, physical maturation (eyelid opening), and puberty
                onset (vaginal opening) in the female offspring. Genistein and tamoxifen had similar effects on puberty
                onset than E2.</strong> Zearalenone caused persistent cornification of the estrus smears. These findings
            indicate that <strong>maternal exposure to physiological doses of genistein mimics the effects of E2 on the
                mammary gland and reproductive systems in the offspring. Thus, our results suggest that genistein acts
                as an estrogen in utero, and may increase the incidence of mammary tumors if given through a pregnant
                mother.
            </strong>

            The estrogenic effects of zearalenone on the mammary gland, in contrast, are probably counteracted by the
            permanent changes in estrus cycling.

            Ishizuki Y; Hirooka Y; Murata Y; Togashi K Nippon Naibunpi Gakkai Zasshi, 1991 May 20, 67:5, 622-9 To
            elucidate whether soybeans would suppress the thyroid function in healthy adults, we selected 37 subjects
            who had never had goiters or serum antithyroid antibodies. They were given 30g of soybeans everyday and were
            divided into 3 groups subject to age and duration of soybean administration. In group 1, 20 subjects were
            given soybeans for 1 month. Groups 2 and 3 were composed of 7 younger subjects (mean 29 y.o.) and 10 elder
            subjects (mean 61 y.o.) respectively, and the subjects belonging to these groups received soybeans for 3
            months. The Wilcoxon-test and t-test were used in the statistical analyses. In all groups, the various
            parameters of serum thyroid hormones remained unchanged by taking soybeans, however TSH levels rose
            significantly although they stayed within normal ranges. The TSH response after TRH stimulation in group 3
            revealed a more significant increase than that in group 2, although inorganic iodide levels were lowered
            during the administration of the soybeans. We have not obtained any significant correlation between serum
            inorganic iodide and TSH. Hypometabolic symptoms (malaise, constipation, sleepiness) and goiters appeared in
            half the subjects in groups 2 and 3 after taking soybeans for 3 months, but they disappeared 1 month after
            the cessation of soybean ingestion. These findings suggested that excessive soybean ingestion for a certain
            duration might suppress thyroid function and cause goiters in healthy people, especially elderly subjects.

                in Austria.</strong>
            Iodine excretion and thyroid function were therefore investigated in 80 patients suffering from ordinary
            goiter in whom thyroid size and resulting symptoms had increased lately. 25 euthyroid non-goitrous subjects
            served as controls. 48% of the goitrous patients investigated presented with iodine excretion of less than
            70 micrograms/24 h, suggesting an insufficient iodine supply. Thyroid I131 uptake, basal and TRH-stimulated
            plasma TSH concentrations, and serum T3 levels were higher, whereas serum T4 levels were lower in these
            patients than in goitrous patients with higher iodine excretion and non-goitrous controls. Iodine deficiency

            ZJ Environmental Toxicology Program, University of Alabama, Birmingham 35294, USA. J Toxicol Environ Health,
            1997 Jan, 50:1, 1-29. Estrogen-like chemicals are unique compared to nonestrogenic xenobiotics, because in
            addition to their chemical properties, the estrogenic property of these compounds allows them to act like
            sex hormones. <strong>
                Whether weak or strong, the estrogenic response of a chemical, if not overcome, will add extra
                estrogenic burden to the system. At elevated doses, natural estrogens and environmental estrogen-like
                chemicals are known to produce adverse effects. The source of extra or elevated concentration of
                estrogen could be either endogenous or exogenous.</strong> The potential of exposure for humans and
            animals to environmental estrogen-like chemicals is high. Only a limited number of estrogen-like compounds,
            such as diethylstilbestrol (DES), bisphenol A, nonylphenol, polychlorinated biphenyls (PCBs), and
            dichlorodiphenyltrichloroethane (DDT), have been used to assess the biochemical and molecular changes at the
            cellular level. Among them, DES is the most extensively studied estrogen-like chemical, and therefore this
            article is focused mainly on DES-related observations. In addition to estrogenic effects, environmental
            estrogen-like chemicals <strong>produce multiple and multitype genetic and/or nongenetic hits.</strong>
            Exposure of Syrian hamsters to stilbene estrogen (DES) produces several changes in the nuclei of target
            organ for carcinogenesis (kidney): (1) Products of nuclear redox reactions of DES modify transcription
            regulating proteins and DNA; (2) transcription is inhibited; (3) tyrosine phosphorylation of nuclear
            proteins, including RNA polymerase II, p53, and nuclear insulin-like growth factor-1 receptor, is altered;
            and (4<strong>) DNA repair gene DNA polymerase beta transcripts are decreased and mutated.</strong> Exposure
            of Noble rats to DES also produces several changes in the mammary gland: proliferative activity is
            drastically altered; the cell cycle of mammary epithelial cells is perturbed; telomeric length is
            attenuated; etc. It appears that some other estrogenic compounds, such as bisphenol A and nonylphenol, may
            also follow a similar pattern of effects to DES, because we have recently shown that these compounds <strong
            >alter cell cycle kinetics, produce telomeric associations, and produce chromosomal aberrations.
            </strong>

            Like DES, bisphenol A after metabolic activation is capable of binding to DNA. However, it should be noted
            that a particular or multitype hit(s) will depend upon the nature of the environmental estrogen-like
            chemical. The role of individual attack leading to a particular change is not clear at this stage.
            Consequences of these multitypes of attack on the nuclei of cells could be (1) nuclear toxicity/cell death;
            (2) repair of all the hits and then acting as normal cells; or (3) sustaining most of the hits and acting as
            unstable cells. Proliferation of the last type of cell is expected to result in transformed cells.

            <strong>Potential adverse effects of phytoestrogens.</strong> Whitten PL; Lewis C; Russell E; Naftolin F

            Evaluation of the potential benefits and risks offered by naturally occurring plant estrogens requires
            investigation of their potency and sites of action when consumed at natural dietary concentrations. Our
            investigations have examined the effects of a range of natural dietary concentrations of the most potent
            plant isoflavonoid, coumestrol, using a rat model and a variety of estrogen-dependent tissues and endpoints.
            Treatments of immature<strong>
                females demonstrated agonistic action in the reproductive tract, brain, and pituitary at natural dietary
                concentrations. Experiments designed to test for estrogen antagonism demonstrated that coumestrol did
                not conform to the picture of a classic antiestrogen.
            </strong>
            However, coumestrol did suppress estrous cycles in adult females. Developmental actions were examined by
            neonatal exposure of pups through milk of rat dams fed a coumestrol, control, or commercial soy-based diet
            during the critical period of the first 10 postnatal days or throughout the 21 days of lactation. The 10-day
            treatment did not significantly alter adult estrous cyclicity, but the 21-day treatment produced in a
            <strong>persistent estrus state in coumestrol-treated females by 132 days of age.</strong> In contrast, the
            10-day coumestrol treatments produced <strong>significant deficits in the sexual behavior of male
                offspring.</strong> These findings illustrate the broad range of actions of these natural estrogens and
            the variability in potency across endpoints. This variability argues for the importance of fully
            characterizing each phytoestrogen in terms of its sites of action, balance of agonistic and antagonistic
            properties, natural potency, and short-term and long-term effects.

                Age-related changes in the female hormonal environment during reproductive life.</strong> Musey VC,
            Collins DC, Musey PI, Martino-Saltzman D, Preedy JR. Previous studies have indicated that serum levels of
            follicle-stimulating hormone rise with age during the female reproductive life, but the effect on other
            hormones is not clear. We studied the effects of age, independent of pregnancy, by comparing serum hormone
            levels in two groups of nulliparous,<strong>
                premenopausal women aged 18 to 23 and 29 to 40 years. We found that increased age during reproductive
                life is accompanied by a significant rise in both basal and stimulated serum follicle-stimulating
                hormone levels. This was accompanied by an increase in the serum level of estradiol-17 beta and the
                urine levels of estradiol-17 beta and 17 beta-estradiol-17-glucosiduronate.</strong> The serum level of
            estrone sulfate decreased with age. Serum and urine levels of other estrogens were unchanged. The basal and
            stimulated levels of luteinizing hormone were also unchanged. There was a significant decrease in basal and
            stimulated serum prolactin levels. Serum levels of dehydroepiandrosterone and dehydroepiandrosterone sulfate
            decreased with age, but serum testosterone was unchanged. It is concluded that significant age-related
            changes in the female hormonal environment occur during the reproductive years.

                tool for reproductive aging studies in the female rat.</strong>
            Biology of Reproduction, v.49, n.2, (1993): 387-392. The present study was designed to determine whether the
            modification of exposure time to large doses of estrogens provided a reliable model for early changes in
            reproductive aging. Silastic implants containing estradiol benzoate (EB) in solution were placed into
            5-day-old female Wistar rats and removed 1 day (Ei1 group) or 5 days (Ei5) later. In addition, 100 mu-g EB
            dissolved in 100 mu-l corn oil was administered s.c. to another group (EI). Control rats received either
            vehicle implants or 100 mu-l corn oil. Premature occurrence of vaginal opening was observed in all three
            estrogenized groups independently of EB exposure. However, females bearing implants for 24 h had first
            estrus at the same age as their controls and cycled regularly, and neither histological nor gonadal
            alterations could be observed at 75 days.. Interestingly, they failed to cycle regularly at 5 mo whereas
            controls continued to cycle. On the other hand, the increase of EB exposure (Ei5, EI) resulted in a gradual
            and significant delay in the onset of first estrus and in a high number of estrous phases, as frequently
            observed during reproductive decline. At 75 days, the ovaries of these last two groups showed a reduced
            number of corpora lutea and an increased number of large follicles. According to this histological pattern,
            ovarian weight and <strong>progesterone (P) content gradually decreased whereas both groups showed higher
                estradiol (E-2) content</strong> than controls. This resulted in <strong>a higher E-2:P ratio,
                comparable to that observed in normal aging rats.</strong> The results allow us to conclude that the
            exposure time to large doses of estrogens is critical to the gradual enhancement of reproductive decline.
            Furthermore, exposures as brief as 24 h led to a potential early model for aging studies that will be useful
            to verify whether neuroendocrine changes precede gonadal impairment.

            Lansing 48824-1316. Disruption of hypothalamic sex differentiation in the fetus is one hypothesis to explain
            female reproductive system anomalies and cancer arising from prenatal exposure to diethylstilbestrol (DES).
            To further test this hypothesis, breeding performance and behavior were monitored in a colony of mice
            exposed prenatally to DES, using a schedule previously shown to produce anomalies and cancer of the female
            reproductive system. <strong>
                Fertility decreased with age more rapidly in DES-exposed females than in control females.</strong>
            DES-exposed females were less accepting of the male than control females. These observations support the
            hypothesis of abnormal hypothalamic sex differentiation as a basic mechanism in DES transplacental

            restored the PFC response of the male offspring. In the adult mice fed differently pre- and perinatally the
            resistance to a transplanted syngeneic sarcoma was similar. The growth of offspring from mice fed the three
            diets was similar. In mice deprived of animal fat at weaning and for the following 21 days the immune
            reactivity to SRBC, tested about 3 months after stopping the diet, was not influenced. However, the
            resistance to a transplanted tumour in similarly fed mice was increased and this resistance was brought
            approximately to the control level by methoxy-substituted glycerol ethers.

                Effects of dietary fats and soybean protein on azaserine-induced pancreatic carcinogenesis and plasma
                cholecystokinin in the rat.</strong> Roebuck BD, Kaplita PV, Edwards BR, Praissman M<strong>
                Both dietary unsaturated fat and raw soybean products are known to enhance pancreatic carcinogenesis
                when fed during the postinitiation phase. A comparison of these two dietary components was made
                to</strong> evaluate the relative potency of each ingredient for enhancing pancreatic carcinogenesis and
            to determine if this enhancement was correlated with an increase in plasma cholecystokinin (CCK) levels.
            Male Wistar rats were initiated with a single dose of azaserine (30 mg/kg body weight) at 14 days of age.
            The rats were weaned to test diets formulated from purified ingredients. Dietary protein at 20% by weight
            was either casein or soy protein isolate (heat treated or raw).. Corn oil was the unsaturated fat of major
            interest and it was fed at either 5 or 20% by weight. Pancreases were quantitatively evaluated for
            carcinogen-induced lesions at 2- and 4-month postinitiation. In a second experiment designed to closely
            mimic the above experiment, rats were implanted with cannulae which allowed plasma to be repetitively
            sampled over a 2.5-week period during which the test diets were fed. Plasma was collected both prior to
            introduction of the test diets and afterwards. Plasma CCK was measured by a specific radioimmunoassay. Both
            the 20% corn oil diet and the raw soy protein isolate diet enhanced pancreatic carcinogenesis. The effects
            of the raw soy protein isolate on the growth of the carcinogen-induced lesions were significantly greater
            than the effects of the 20% corn oil diet. Plasma CCK values were not elevated in the rats fed the 20% corn
            oil diet, but they were significantly elevated in the rats fed the raw soy protein isolate. Heat-treated soy
            protein isolate neither enhanced carcinogenesis nor elevated the plasma CCK level. This<strong>
                study demonstrates that certain plant proteins enhance the growth of carcinogen-induced pancreatic foci
                and that this effect is considerably greater than the enhancement by high levels of dietary unsaturated
                fat. Furthermore, the enhancement by the raw soy protein isolate may be mediated by CCK; but this does
                not appear to be the mechanism by which the unsaturated fat, corn oil, enhances pancreatic
                carcinogenesis.</strong>

            from human uterus, breast, and melanoma. Binding was analyzed after separation with dextran-coated charcoal
            or hydroxylapatite and by sucrose density gradient centrifugation. <strong>
                Unsaturated NEFAs induced a 2- to 10-fold increase (P less than 0.001) in E2 binding to cytosol
            </strong>from normal, fibromatous, and neoplastic uteri, while saturated NEFAs<strong>
                had a slight inhibitory effect</strong> (P less than 0.05). Similar effects were seen with cytosol from
            metastatic melanoma lymph nodes and neoplastic breast tissues. By contrast, unsaturated NEFAs did not
            increase E2 binding to serum from these patients. Density gradient centrifugation indicated that the
            increased binding was associated with the proteins present in the 2- to 4 S region. Analysis of E2
            metabolites in the presence of unsaturated NEFAs showed the formation of water-soluble derivatives. Seventy
            percent of these E2 derivatives were trichloracetic acid precipitable, suggesting a covalent link between
            the steroid and a protein. The existence of such water-soluble metabolites could be erroneously interpreted
            as a true binding to soluble cytoplasmic receptors.

                Fiber, stool bulk, and bile acid output: implications for colon cancer risk.</strong> McPherson-Kay R
            Dietary fiber has direct effects on stool bulk and bile acid output that may be of relevance in the etiology
            of colon cancer. Most types of fiber increase the total volume of stool and reduce the concentration of
            specific substances, including bile acids, that are in contact with the bowel wall. However, fibers differ
            in their effect on stool bulk, with wheat fiber being a more effective stool bulking agent than fruit and
            vegetable fibers. In addition, the extent to which a specific fiber reduces bile acid concentration will be
            modified by its concomitant effects on total fecal sterol excretion. Whereas wheat bran reduces fecal bile
            acid concentration, <strong>pectin, lignin, and oat bran do not. These three fibers significantly increase

                altering transit-time.</strong> Lewis SJ, Oakey RE, Heaton KW University Department of Medicine, Bristol
            Royal Infirmary, UK. OBJECTIVE: The mechanism by which a high fibre diet may reduce serum oestrogens is
            unknown. We hypothesized that time is a rate-limiting factor in oestrogen absorption from the colon so that
            changes in colonic transit-rate affect the proportion of oestrogen that is deconjugated and/or absorbed.
            AIM: To determine if alteration of intestinal transit rate would influence the absorption of an oral dose of
            oestradiol glucuronide. PARTICIPANTS: Twenty healthy postmenopausal women recruited by advertisement.
            SETTING: Department of Medicine, Bristol Royal Infirmary. METHODS: Volunteers consumed, in turn, wheat bran,
            senna, loperamide and bran shaped plastic flakes, each for 10 days with a minimum 2 week washout period
            between study periods, dietary intake being unchanged. Before and in the last 4 days of each intervention
            whole-gut transit-time, defecation frequency, stool form, stool beta-glucuronidase activity, stool pH and
            the absorption of a 1.5 mg dose of oestradiol glucuronide were measured. RESULTS: Wheat bran, senna and
            plastic flakes led to the intended reduction in whole-gut transit-time, increase in defecatory frequency and
            increase in stool form score. Loperamide caused the opposite effect. <strong>The length of time the absorbed
                oestrogen was detectable in the serum fell with wheat bran and senna, although this was only significant
                for oestradiol.</strong>
            Oestrone, but not oestradiol, was detectable for a longer time with loperamide. Plastic flakes had no effect
            on either oestrogen. Areas under the curve did not change significantly but tended to fall with the three
            transit-accelerating agents and to rise with loperamide. CONCLUSION: Our data indicate there is likely to be
            an effect of intestinal transit on the absorption of oestrogens but more refined techniques are needed to
            characterize this properly.

                Lower serum oestrogen concentrations associated with faster intestinal transit.</strong> Lewis SJ,
            Heaton KW, Oakey RE, McGarrigle HH University Department of Medicine, Bristol Royal Infirmary, UK. Increased
            fibre intake has been shown to reduce serum oestrogen concentrations. We hypothesized that fibre exerts this
            effect by decreasing the time available for reabsorption of oestrogens in the colon. We tested this in
            volunteers by measuring changes in serum oestrogen levels in response to manipulation of intestinal transit
            times with senna and loperamide, then comparing the results with changes caused by wheat bran. Forty healthy
            premenopausal volunteers were placed at random into one of three groups. The first group took senna for two
            menstrual cycles then, after a washout period, took wheat bran, again for two menstrual cycles. The second
            group did the reverse. The third group took loperamide for two menstrual cycles. At the beginning and end of
            each intervention a 4-day dietary record was kept and whole-gut transit time was measured; stools were taken
            for measurement of pH and beta-glucuronidase activity and blood for measurement of oestrone and oestradiol
            and their non-protein-bound fractions and of oestrone sulphate. <strong>
                Senna and loperamide caused the intended alterations in intestinal transit, whereas on wheat bran
                supplements there was a trend towards faster transit. Serum oestrone sulphate fell with wheat bran (mean
                intake 19.8 g day(-1)) and with senna; total- and non-protein-bound oestrone fell with senna.</strong>
            No significant changes in serum oestrogens were seen with loperamide. No significant changes were seen in
            faecal beta-glucuronidase activity. Stool pH changed only with senna, in which case it fell. In conclusion,
            speeding up intestinal transit can lower serum oestrogen concentrations.

                tumor development, plasma estrogen levels and estrogen excretion in female rats.</strong> Arts CJ, de
            Bie AT, van den Berg H, van 't Veer P, Bunnik GS, Thijssen JH TNO Toxicology and Nutrition Institute, The
            Netherlands. In our animal experiments the hypothesis was tested that a high-fiber (HF) diet reduces tumor
            promotion<strong>
                by interruption of the enterohepatic circulation resulting in lowered estrogen exposure of the
                estrogen-sensitive tissue.
            </strong>

            In the first experiment the development of N-nitrosomethylurea (NMU) induced mammary tumors was
            investigated. One group of rats (HF) was fed a HF diet (11% fiber, based on wheat bran), the other group
            (LF) fed a low-fiber diet (0.5% fiber, based on white wheat flour). Tumor incidence (90 and 80%,
            respectively) and latency (121 and 128 days, respectively) were similar in the HF and LF groups. Compared to
            the LF group, HF rats had lower tumor weights (0.16 vs 0.55 g; P less than 0.01) and a slightly lower tumor
            multiplicity (1.8 vs 2.8 tumors per tumor-bearing rat). These differences were reduced after adjustment for
            body weight. In a second experiment rats, not treated with the carcinogen, were kept on the same HF and LF
            diets. From these rats 24-h urine and feces and orbital blood samples were<strong>
                collected for analysis of (un)conjugated estrogens. The excretion of both free and conjugated estrogens
                in fecal samples was about 3-fold higher in HF rats than in LF rats. During the basal period of the
                cycle urinary excretion of estrone was lower in HF rats (mean 9.7 ng/day) than in LF rats (mean 13.0
                ng/day; P less than 0.05). It is concluded that wheat bran interrupts the enterohepatic circulation of
                estrogens, but plasma levels are not affected. Whether the development of mammary tumors is reduced by
                the introduction of specific components of wheat bran, or by a reduced body weight due to a lower
                (effective) energy intake remains to be determined.

            suggested potential breast cancer-preventive properties of dietary fiber from cabbage. The purpose of the
            present investigation was to determine whether lignin, a component of cabbage fiber, would protect against
            mammary carcinogenesis by N-methyl-N-nitrosourea (MNU) in Sprague-Dawley rats. A six-week study was
            conducted using diets containing 0.5-5% dietary wood lignin (a readily available, purified source). These
            diets were well tolerated by the rats, and a carcinogenesis study using 5 mg MNU/100 g body wt i.v. at 50
            days of age was conducted, with the 2.5% lignin diet fed from 6 through 8 weeks of age followed by 5% lignin
            diet until 20 weeks after MNU. Dietary lignin and MNU treatment increased food consumption (p &lt; 0.05),
            and body weight was slightly reduced at 10 and 20 weeks after MNU in the MNU-5% lignin diet group (p &lt;
            0.05). Serum estradiol was not altered by dietary lignin or MNU treatment, but uterine weights were highest
            in the MNU-control diet group 4 and 12 weeks after MNU. Expression of creatine kinase B, an
            estrogen-responsive gene, was lower in the uteri of the MNU-lignin diet group than in other groups at 20
            weeks. Mammary carcinogenesis was not altered by dietary lignin.<strong>
                However, uterine endometrial adenocarcinoma was observed only in the MNU-lignin diet group (4
                carcinomas/40 effective rats) (p &lt; 0.05).

            Oils in Context
        </h1>

        <p>
            An oil researcher<sup>[0]</sup>

            spent 100 days eating what he considered to be the "Eskimo diet," seal blubber and mackerel paste. He
            observed that his blood lipid peroxides (measured as malondialdehyde, MDA) reached a level 50 times higher
            than normal, and although MDA is teratogenic, he said he wasn't worried about fathering deformed children,
            because his sperm count had gone to zero. Evidently, he didn't have a very thorough understanding of the
            Eskimo way of life. In most traditional cultures, the whole animal is used for food, including the brain and
            the endocrine glands. Since unsaturated fats inhibit thyroid function, and since Eskimos usually have a high
            caloric intake but are not typically obese, it seems that` their metabolic rate is being promoted by
            something in their diet, which might also be responsible for protecting them from the effects experienced by
            the oil researcher. (According to G. W. Crile, the basal metabolic rate of Eskimos was 125% of that of
            people in the United States.)
        </p>
        <p>
            People who eat fish heads (or other animal heads) generally consume the thyroid gland, as well as the brain.
            The brain is the body's richest source of cholesterol, which, with adequate thyroid hormone and vitamin A,
            is converted into the steroid hormones pregnenolone, progesterone, and DHEA, in proportion to the quantity
            circulating in blood in low-density lipoproteins. The brain is also the richest source of these very
            water-insoluble (hydrophobic) steroid hormones; it has a concentration about 20 times higher than the serum,
            for example. The active thyroid hormone is also concentrated many-fold in the brain.
        </p>
        <p>
            DHEA (dehydroepiandrosterone) is known to be low in people who are susceptible to heart disease <sup
            >[1]</sup> or cancer, and all three of these steroids have a broad spectrum of protective actions. Thyroid
            hormone, vitamin A, and cholesterol, which are used to produce the protective steroids, have been found to
            have a similarly broad range of protective effects, even when used singly. For example, according to
            MacCallum,
        </p>
        <p>
            It has been shown that certain lipoid substances, especially cholesterine, can act as inhibiting or
            neutralizing agents toward such haemolytic poisons as saponin, cobra poison, etc., through forming with them
            an innocuous compound. Hanes showed that the relative immunity of puppies from chloroform poisoning is due
            to the large amount of cholesterin esters in their tissues. When artificially introduced into the tissues of
            adult animals a similar protection is conferred.<sup>[2]</sup>
        </p>
        <p>
            A high level of serum cholesterol is practically diagnostic of hypothyroidism, and can be seen as an
            adaptive attempt to maintain adequate production of the protective steroids. Broda Barnes' work clearly
            showed that hypothyroid populations are susceptible to infections, heart disease, and cancer. <sup>[3]</sup>
        </p>
        <p>
            In the 1940s, some of the toxic effects of fish oil (such as testicular degeneration, softening of the
            brain, muscle damage, and spontaneous cancer) were found to result from an induced vitamin E deficiency.
            Unfortunately, there isn't much reason to think that just supplementing vitamin E will provide general
            protection against the unsaturated fats. The half-life of fats in human adipose tissue is about 600 days,
            meaning that significant amounts of previously consumed oils will still be present up to four years after
            they have been removed from the diet. <sup>[4]</sup>

            <strong>, , , </strong>
            enrichment of the tissues with highly unsaturated fatty acids results in an increase in lipid peroxidation
            in vivo even in the presence of normal concentrations of vitamin E. Fasting for more than 24 hours also
            results in an increase in MDA excretion, implying that lipolysis is associated with peroxidation of the
            fatty acids released.

            Commercial advertising (including medical conferences sponsored by pharmaceutical companies) and
            commercially sponsored research are creating some false impressions about the role of unsaturated oils in
            the diet. Like the man who poisoned himself with the "Eskimo diet," many people focus so intently on
            avoiding one problem that they create other problems. Since I have discussed the association of unsaturated
            fats with aging, lipofuscin, and estrogen elsewhere, I will outline some of the other problems associated
            with the oils, especially as they relate to hormones.

            <strong>Mechanisms and Essentiality:
            </strong> When something is unavoidable, in ordinary life, talking about "essentiality," or the minimum
            amount required for life or for optimal health, is more important as an exploration into the nature of our
            life than as a practical health issue. For example, how much oxygen, how many germs (of what kinds), how
            many cosmic rays (of what kinds), would produce the nicest human beings? The fact that we have adapted to
            something---oxygen at sea level, microbes, or vegetable fats, for example--doesn't mean that we are normally
            exposed to it in ideal amounts.
        </p>

        <p>
            Animals contain desaturase enzymes, and are able to produce specific unsaturated fats (from oleic and
            palmitoleic acids) when deprived of the ordinary "essential fatty acids," <sup>[7]</sup> so it can be
            assumed that these enzymes have a vital purpose. The high concentration of unsaturated fats in
            mitochondria--the respiratory organelles where it seems that these lipids present a special danger of
            destructive oxidation--suggests that they are required for mitochondrial structure, or function, or
            regulation, or reproduction. Unsaturated fats have special properties of adsorption, <sup>[8]</sup> and are
            more soluble in water than are saturated fats. The movement and modulation of proteins and nucleic acids
            might require these special properties. As the main site of ATP production, I suspect that their
            water-retaining property might be crucial. When a protein solution (even egg-white) is poured into a high
            concentration of ATP, it contracts or "superprecipitates." This condensing, water-expelling property of ATP
            in protein solutions is similar to the effect of certain concentrations of salts on any polymer. It would
            seem appropriate to have a substance to oppose this condensing effect, to stimulate swelling <sup>[9,
                10]</sup> and the uptake of precursor substances. Something that has an intrinsic structure-loosening or
            water-retaining effect would be needed. The ideas of "chaotropic agents" and "structural antioxidants" have
            been proposed by Vladimirov <sup>[11]</sup> to bring generality into our understanding of the mitochondria.
            Lipid peroxides are among the chaotropic agents, and thyroxin is among the structural antioxidants. The
            known oxygen-sparing effects of progesterone <sup>[12, 13]</sup> would make it appropriate to include it
            among the structural antioxidants. The incorporation of the wrong unsaturated fats into mitochondria would
            be expected to damage the vital respiratory functions.

            Some insects that have been studied have been found not to require the essential fatty acids. <sup>[14]</sup
            >* According to reviewers, hogs and humans have not been shown to require the "essential" fatty acids. <sup
            >[15]</sup> In vitro studies indicate that they are not required for human diploid cells to continue
            dividing in culture. <sup>
                [16]
            </sup> According to Guarnieri, <sup>[17]</sup> EFA-deficient animals don't die from their deficiency. The
            early studies showing "essentiality" of unsaturated fats, by producing skin problems and an increased
            metabolic rate, have been criticized <sup>[18]</sup> in the light of better nutritional information, e.g.,
            pointing out that the diets might have been deficient in vitamin B6 and/or biotin. The similar skin
            condition produced by vitamin B6 deficiency was found to be improved by adding unsaturated fats to the diet.
            A fat-free liver extract cured the "EFA deficiency." I think it would be reasonable to investigate the
            question of the increased metabolic rate produced by a diet lacking unsaturated fats (which inhibit both
            thyroid function and protein metabolism) in relation to the biological changes that have been observed.
            Since diets rich in protein are known to increase the requirement for vitamin B6 <sup>[19]</sup> (which is a
            co-factor of transaminases, for example), the increased rate of energy production and improved digestibility
            of dietary protein on a diet lacking unsaturated fats would certainly make it reasonable to provide the
            experimental animals with increased amount of other nutrients. With increasing knowledge, the old
            experiments indicating the "essentiality" of certain oils have lost their ability to convince, and they
            haven't been replaced by new and meaningful demonstrations. In the present state of knowledge, I don't think
            it would be unreasonable to suggest that the optional dietary level of the "essential fatty acids" might be
            close to zero, if other dietary factors were also optimized. The practical question, though, has to do with
            the dietary choices that can be made at the present time.

            *If we followed Linus Pauling's reasoning in determining optimal vitamin C intake, this study of the
            linoleic acid content of the tissues of an animal which can synthesize it would suggest that we are eating
            about 100 times more "EFA" than we should.
        </p>
        <p>
            In evaluating dietary fat, it is too often forgotten that the animals' diet (and other factors, including
            temperature) affect the degree of saturation of fats in its tissues, or its milk, or eggs. The fat of wild
            rabbits or summer-grazing horses, for example, can contain 40% linolenic acid, about the same as linseed
            oil. Hogs fed soybeans can have fat containing over 30% linoleic acid. <sup>[20]</sup>
            Considering that most of our food animals are fed large amounts of grains and soybeans, it isn't accurate to
            speak of their fats as "animal fats." And, considering the vegetable oil contained in our milk, eggs, and
            meat, it would seem logical to select other foods that are not rich in unsaturated oils.
        </p>
        <p>
            <strong>Temperature and Fat:</strong> The fact that saturated fats are dominant in tropical plants and in
            warm-blooded animals relates to the stability of these oils at high temperatures. Coconut oil which had been
            stored at room temperature for a year was found to have no measurable rancidity. Since growing coconuts
            often experience temperatures around 100 degrees Fahrenheit, ordinary room temperature isn't an oxidative
            challenge. Fish oil or safflower oil, though, can't be stored long at room temperature, and at 98 degrees F,
            the spontaneous oxidation is very fast.
        </p>

        <p>
            Bacteria vary the kind of fat they synthesize, according to temperature, forming more saturated fats at
            higher temperatures.<sup>[21]</sup> The same thing has been observed in seed oil plants. <sup>[22]</sup>
            Although sheep have highly saturated fat, the superficial fat near their skin is relatively unsaturated; it
            would obviously be inconvenient for the sheep if their surface fat hardened in cool weather, when their skin
            temperature drops considerably. Pigs wearing sweaters were found to have more saturated fat than other
            pigs.<sup>[23]</sup>
            Fish, which often live in water which is only a few degrees above freezing, couldn't function with hardened
            fat. At temperatures which are normal for fish, and for seeds which germinate in the cold northern
            springtime, rancidity of fats isn't a problem, but rigidity would be.

            <strong>Unsaturated Fats Are Essentially Involved In Heart Damage:
            </strong>
            The toxicity of unsaturated oils for the heart is well established, <sup>
                [24, 25, 26]</sup> though not well known by the public.
        </p>

        <p>
            In 1962, it was found that unsaturated fatty acids are directly toxic to mitochondria. <sup>[27]</sup> Since
            stress increases the amount of free fatty acids circulating in the blood (as well as lipid peroxides), and
            since lack of oxygen increases the intracellular concentration of free fatty acids, stored unsaturated fats
            would seem to represent a special danger to the stressed organism. Meerson and his colleagues <sup>
                [18]</sup> have demonstrated that stress liberates even local tissue fats in the heart during stress,
            and that systematic drug treatment, including antioxidants, can stop the enlargement of stress-induced
            infarctions. Recently, it was found that the cardiac necrosis caused by unsaturated fats (linolenic acid, in
            particular) could be prevented by a cocoa butter supplement. <sup>[29]</sup> The author suggests that this
            is evidence for the "essentiality" of saturated fats, but points out that animals normally can produce
            enough saturated fat from dietary carbohydrate or protein, to prevent cardiac necrosis, unless the diet
            provides too much unsaturated fat. A certain proportion of saturated fat appears to be necessary for
            stability of the mitochondria. Several other recent studies show that the "essential" fatty acids decrease
            the P/O ratio, or the phosphorylation efficiency, <sup>[30]</sup> the amount of usable energy produced by
            cellular respiration.

            There has been some publicity about a certain unsaturated fat, eicosapentaenoic acid, or EPA, which can have
            some apparently protective and anti-inflammatory effects. A study in which butter was added to the animals'
            diet found that serum EPA was elevated by the butter. The investigator pointed out that other studies had
            been able to show increased serum EPA from an EPA supplement only when the animals had previously been fed
            butter.<sup> [31]</sup>

            Intense lobbying by the soybean oil industry has created the widespread belief that "tropical oils" cause
            heart disease. In a comparison of many kinds of oil, including linseed oil, olive oil, whale oil, etc., palm
            oil appeared to be the most protective. The same researcher <sup>
                [32]</sup> more recently studied palm oil's antithrombotic effect, in relation to platelet aggregation.
            It was found that platelet aggregation was enhanced by sunflowerseed oil, but that palm oil tended to
            decrease it.

            Much current research has concentrated on the factors involved in arterial clotting. Since the blood moves
            quickly through the arteries, rapid processes are of most interest to those workers, though some people do
            remember to think in terms of an equilibrium between formation and removal of clot material. For about 25
            years there was interest in the ability of vitamin E to facilitate clot removal, apparently by activating
            proteolytic enzymes.<sup>[33]</sup> Unsaturated fats' ability to inhibit proteolytic enzymes in the blood
            has occasionally been discussed, but seldom in the U.S. The equilibrium between clotting and clot
            dissolution is especially important in the veins, where blood moves more slowly, and spends more time.

        <p>
            <strong>. . . </strong>
            the slower blood flows the greater its predisposition to clotting. However, this intrinsic process, leading
            to fibrin production, is slow, taking up to a minute or more to occur. Thrombosis as a result of stasis,
            therefore, occurs in the venous circulation; typically in the legs where"venous return is slowest. In fact,
            many thousands of small thrombi are formed each day in the lower body. These pass via the vena cava into the
            lungs where thrombolysis occurs, this being a normal metabolic function of the organ. <sup>[34]</sup>

        <p>
            In the Shutes' research in the 1930s and 1040s, vitamin E and estrogen acted in opposite directions on the
            clot-removing enzymes.<sup>[33]</sup>
            Since estrogen increases blood lipids, and increases the incidence of strokes and heart attacks, it would be
            interesting to expand the Shutes' work by considering the degree of saturation of blood lipids in relation
            to the effects of vitamin E and estrogen on clot removal. Estrogen's effect on clotting is very complex,
            since it increases the ratio of unsaturated to saturated fatty acids in the body, and increases the tendency
            of blood to pool in the large veins, in addition to its direct effects on the clotting factors.

            <strong>Immunodeficiency and Unsaturated Fats:
            </strong>Intravenous feeding with unsaturated fats is powerfully immunosuppressive <sup>[35]</sup> (though
            it often was used to give more calories to cancer patients) and is now advocated as a way to prevent graft
            rejection. The deadly effect of the long-chain unsaturated fats on the immune system has led to the
            development of new products containing short and medium-chain saturated fats for intravenous feeding. <sup
            >[36]</sup> It was recently reported that the anti-inflammatory effect of n-3 fatty acids (fish oil) might
            be related to the observed suppression of interleukin-1 and tumor necrosis factor by those fats. <sup
            >[37]</sup> The suppression of these anti-tumor immune factors persists after the fish oil treatment is
            stopped.
        </p>

        <p>
            As mentioned above, stress and hypoxia can cause cells to take up large amounts of fatty acids. Cortisol's
            ability to kill white blood cells (which can be inhibited by extra glucose) is undoubtedly an important part
            of its immunosuppressive effect, and this killing is mediated by causing the cells to take up unsaturated
            fats. <sup>[38]</sup>
        </p>
        <p>
            Several aspects of the immune system are improved by short-chain saturated fats. Their anti-histamine action
            <sup>[39]</sup> is probably important, because of histamine's immunosuppressive effects.<sup>[40]</sup>
            Unsaturated fats have been found to cause degranulation of mast cells.<sup>[41]</sup>
            The short-chain fatty acids normally produced by bacteria in the bowel apparently have a local

            A recent discussion of "tissue destruction by neutrophils" mentions "a fascinating series of experiments

            MacCallum's <em>Pathology </em>described some related work:

        <p>
            <strong>. . . </strong>
            Jobling has shown that the decomposition products of some fats--unsaturated fatty acids and their
            soaps--have the most decisive inhibiting action upon proteolytic ferments, their power being in a sense
            proportional to the degree of unsaturation of the fatty acid. So universally is it true that such
            unsaturated fatty acids can impede the action of proteolytic ferments that many pathological conditions
            (such as the persistence of caseous tuberculous material in its solid form) can be shown to be due to their
            presence. If they are rendered impotent by saturation of their unsaturated group with iodine, the
            proteolysis goes on rapidly and the caseous tubercle or gumma rapidly softens.<sup>[44]</sup>
        </p>
        <p>
            Another comment by MacCallum suggests one way in which unsaturated fats could block the action of cytotoxic
            cells:
        </p>
        <p>
            This function of the wandering cells is, of course, of immediate importance in connection with their task of
            cleaning up the injured area to prepare it for repair. While the proteases thus produced are active in the
            solution of undesirable material, their unbridled action might be detrimental. As a matter of fact, it is
            shown by Jobling and Petersen that the anti-ferment known to be present in the serum and to restrict the
            action of the ferment is a recognizable chemical substance, usually a soap or other combination of an
            unsaturated fatty acid. It is possible to remove or decompose this substance or to saturate the fatty acid
            with iodine and thus release the ferment to its full activity. <sup>[45]</sup>

            <strong>Unsaturated Fats Are Essential For Cancer:
            </strong>
            The inhibition of proteolytic enzymes by unsaturated fats will act at many sites: digestion of protein,
            "digestion" of clots, "digestion" of the colloid in the thyroid gland which releases the hormones, the
            activity of white cells mentioned above, and the normal "digestion" of cytoplasmic proteins involved in
            maintaining a steady state as new proteins are formed and added to the cytoplasm. It has been suggested that
            inhibition of the destruction of intracellular proteins would shift the balance toward growth.<sup>[46]</sup
            >
            Cancer cells are known to have a high level of unsaturated fats,<sup>[47]</sup>

            yet they have a low level of lipid peroxidation;<sup>[48]</sup> lipid peroxidation inhibits growth, and is
            often mentioned as a normal growth restraining factor.<sup>[49]</sup>
        </p>
        <p>
            In 1927, it was observed that a diet lacking fats prevented the development of spontaneous tumors.[50] Many
            subsequent investigators have observed that the unsaturated fats are essential for the development of
            tumors. <sup>[51, 52, 53]</sup> Tumors secrete a factor which mobilizes fats from storage, <sup>[54]</sup>
            presumably guaranteeing their supply in abundance until the adipose tissues are depleted. Saturated
            fats--coconut oil and butter, for example--do not promote tumor growth.<sup>[55]</sup> Olive oil is not a
            strong tumor promoter, but in some experiments it does have a slightly permissive effect on tumor growth.
            <sup>[56, 57]</sup> In some experiments, the carcinogenic action of unsaturated fats could be offset by
            added thyroid, <sup>[57]</sup>

            an observation which might suggest that at least part of the effect of the oil is to inhibit thyroid. Adding
            cystine to the diet (cysteine, the reduced form of cystine, is a thyroid antagonist) also increases the
            tumor incidence.<sup>[58]</sup> In a hyperthyroid state, the ability to quickly oxidize larger amounts of
            the toxic oils would very likely have a protective effect, preventing storage and subsequent peroxidation,
            and reducing the oils' ability to synergize with estrogen.

            Consumption of unsaturated fat has been associated with both skin aging and with the sensitivity of the skin
            to ultraviolet damage, Ultraviolet light-induced skin cancer seems to be mediated by unsaturated fats and

            In a detailed study of the carcinogenicity of different quantities of unsaturated fat, Ip, et al., tested
            levels ranging from 0.5% to 10%, and found that the cancer incidence varied with the amount of "essential
            oils" in the diet. Some of their graphs make the point very clearly:<sup>
                [52}</sup>
        </p>

        <p>
            This suggests that the optimal EFA intake might be 0.5% or less.

            Butter and coconut oil contain significant amounts of the short and medium-chain saturated fatty acids,
            which are very easily metabolized,<sup>[60]</sup>
            inhibit the release of histamine,<sup>[39]</sup> promote differentiation of cancer cells,<sup>[61]</sup>
            tend to counteract the stress-induced proteins,<sup>[62]</sup> decrease the expression of prolactin
            receptors, and promote the expression of the T3 (thyroid) receptor. <sup>[63] </sup>

            (A defect of the thyroid receptor molecule has been identified as an "oncogene," responsible for some
            cancers, as has a defect in the progesterone receptor.)
        </p>
        <p>
            Besides inhibiting the thyroid gland, the unsaturated fats impair intercellular communication,[64] suppress
            several immune functions that relate to cancer, and are present at high concentrations in cancer cells,
            where their antiproteolytic action would be expected to interfere with the proteolytic enzymes and to shift
            the equilibrium toward growth. In the free fatty acid form, the unsaturated fats are toxic to the
            mitochondria, but cancer cells are famous for their compensatory glycolysis.

        <p>
            By using lethargic connective tissue cells known to have a very low propensity to take up unsaturated fats
            <sup>[65]</sup> as controls in comparison with, e.g., breast cancer cells, with a high affinity for fats, it
            is possible to show a "selective" toxicity of oils for cancer cells. However, an in vivo test of an
            alph-linolenic acid ester showed it to have a stimulating effect on breast cancer.<sup>[66]</sup>
            Given a choice, skin fibroblasts demonstrate a very specific preference for oleic acid, over a
            polyunsaturated fat.<sup>[67]</sup>

        <p>
            Even if unsaturated fats were (contrary to the best evidence) selectively toxic for cancer cells, their use
            in cancer chemotherapy would have to deal with the issues of their tendency to cause pulmonary
            embolism,their suppression of immunity including factors specifically involved in cancer resistance, and
            their carcinogenicity.

            <strong>Brain Damage And Lipid Peroxidation:
            </strong>
            When pregnant mice were fed either coconut oil or unsaturated seed oil, the mice that got coconut oil had
            babies with normal brains and intelligence, but the mice exposed to the unsaturated oil had smaller brains,
            and had inferior intelligence. In another experiment, radioactively labeled soy oil was given to nursing
            rats, and it was shown to be massively incorporated into brain cells, and to cause visible structural
            changes in the cells. In 1980, shortly after this study was published in Europe, the U.S. Department of
            Agriculture issued a recommendation against the use of soy oil in infant formulas. More recently, <sup
            >[68]</sup> pregnant rats and their offspring were given soy lecithin with their food, and the exposed
            offspring developed sensorimotor defects.
        </p>
        <p>
            Many other studies have demonstrated that excessive unsaturated dietary fats interfere with learning and
            behavior, <sup>[70, 71]</sup> and the fact that some of the effects can be reduced with antioxidants
            suggests that lipid peroxidation causes some of the damage. Other studies are investigating the involvement
            of lipid peroxidation in seizures.<sup>[72]</sup>
        </p>

        <p>
            The past use of soy oil in artificial milk (and in maternal diets) has probably caused some brain damage.
            The high incidence of neurological defects (e.g., 90%) that has been found among violent criminals suggests
            that it might be worthwhile to look for unusual patterns of brain lipids in violent people.
        </p>
        <p>
            There have been a series of claims that babies' brains or eyes develop better when their diets are
            supplemented with certain unsaturated oils, based on the idea that diets may be deficient in certain types
            of oil, Some experimenters claim that the supplements have improved the mental development of babies, but
            other researchers find that the supplemented babies have poorer mental development. But the oils that are
            added to the babies' diets are derived from fish or algae, and contain a great variety of substances (such
            as vitamins) other than the unsaturated fatty acids, and the researchers consistently fail to control for
            the effects of such substances.
        </p>
        <p>
            It has shown that it is probably impossible to experience a detectable deficiency of linoleic acid outside
            of the laboratory setting,<sup>[69]</sup> but the real issue is probably whether the amount in the normal
            diet is harmful to development. Until the research with animals has produced a better understanding of the
            effects of unsaturated oils, experimenting on human babies seems hard to justify.
        </p>
        <p>
            Marion Diamond, who has studied the improved brain growth in rats given a stimulating environment (which,
            like prenatal progesterone, produced improved intelligence and larger brains), observed that in old age the
            "enriched" rats' brains contained less lipofuscin (age pigment).<sup>[73]</sup>
            It is generally agreed that the unsaturated oils promote the formation of age pigment. The discovery that
            stress or additional cortisone (which, by blocking the use of glucose, forces cells to take up more fat)
            causes accelerated aging of the brain<sup>[74]</sup> should provide new motivation to investigate the
            antistress properties of substances such as the protective steroids mentioned above, and the short-chain
            saturated fats.
        </p>

        <p>
            <strong>Essential for Liver Damage:</strong> Both experimental and epidemiological studies have shown that
            dietary linoleic acid is required for the development of alcoholic liver damage.<sup>[75] </sup>
            Animals fed tallow and ethanol had no liver injury, but even 0.7% or 2.5% linoleic acid with ethanol caused
            fatty liver, necrosis, and inflammation. Dietary cholesterol at a level of 2% was found to cause no
            harm,<sup>[76]</sup>
            but omitting it entirely from the diet caused leakage of amino-transferase enzymes. This effect of the
            absence of cholesterol was very similar to the effects of the presence of linoleic acid with ethanol.
        </p>
        <p>
            <strong>Obesity: </strong>
            For many years studies have been demonstrating that dietary coconut oil causes decreased fat synthesis and
            storage, when compared with diets containing unsaturated fats. More recently, this effect has been discussed
            as a possible treatment for obesity.<sup>[77]</sup>
            The short-chain fats in coconut oil probably improve tissue response to the thyroid hormone (T3), and its
            low content of unsaturated fats might allow a more nearly optimal function of the thyroid gland and of
            mitochondria. A survey of other tropical fruits' content of short and medium chain fatty acids might be
            useful, to find lower calorie foods which contain significant amounts of the shorter-chain fats.
        </p>

        <p>
            <strong>Other Problem Areas:
            </strong> The presence of palmitate in the lung surfactant phospholipids<sup>[78]</sup> suggests that
            maternal overload with unsaturated fats might interfere with the formation of these important substances,
            causing breathing problems in the newborn. The bone-calcium mobilizing effect of prostaglandins suggests
            that dietary fats might affect osteoporosis; the absence of osteoporosis in some tropical populations might
            relate to their consumption of coconut oil and other saturated tropical oils. The steroids which occur in
            association with some seed oils might be nutritionally significant, in the way animal hormones in foods
            undoubtedly are. For example, soy steroids can be converted by bowel bacteria into estrogens. R. Marker, et
            al., found diosgenin (the material in the Mexican yam from which progesterone, etc., are derived) in a palm
            kernel, <em>Balanites aegyptica (Wall)</em>.<sup>[79]</sup>
            Another palm fruit also contains sterols with anti-androgenic and anti-edematous actions.<sup>[80, 81]
            </sup>
        </p>
        <p>
            If the amount of ingested unsaturated fats (inhibitors of protein digestion) were lower, protein
            requirements might be lower.
        </p>

        <p>
            The similar effects of estrogen and of polyunsaturated fats (PUFA) are numerous. They include antagonism to
            vitamin E and thyroid, to respiration and proteolysis; promotion of lipofuscin formation and of clot
            formation, promotion of seizure activity, impairment of brain development and learning; and involvement in
            positive or negative regulation of cell division, depending on cell type.
        </p>
        <p>
            These parallels suggest that the role of PUFA in reproduction might be similar to that of estrogen, namely,
            the promotion of uterine and breast cell proliferation, water uptake, etc. Such parallels should be a
            caution in generalizing from the conditions which are essential for reproduction to the conditions which are
            compatible with full development and full functional capacity. If a certain small amount of dietary PUFA is
            essential for reproduction, but for no other life function, then it is analogous to the brief "estrogen
            surge," which must quickly be balanced by opposing hormones. The present approach to contraception through
            estrogen-induced miscarriage might give way to fertility regulation by diet. A self-actualizing
            pro-longevity diet, low in PUFA, might prolong our characteristically human condition of delayed
            reproductive maturity, and, if PUFA are really essential for reproduction, unsaturated vegetable oils could
            temporarily be added to the diet when reproduction is desired.
        </p>
        <p>
            <strong>Conclusions:</strong>
            Polyunsaturated fats are nearly ubiquitous, but if they are "essential nutrients," in the way vitamin A, or
            lysine, is essential, that has not been demonstrated. It seems clear that they <em>are </em>

            essential for cancer, and that they have other properties which cause them to be toxic at certain levels. It
            might be time to direct research toward determining whether there is a threshold of toxicity, or whether
            they are, like ionizing radiation, toxic at any level.

            <strong>A possible mitochondrial site for toxicity:
            </strong>
            In 1971 I was trying to combine some of the ideas of Albert Szent-Gyorgyi, Otto Warburg, W. F. Koch, and L.
            C. Strong. I was interested in the role of ubiquinone in mitochondrial respiration. In one experiment, I was
            using paper chromatography to compare oils that I had extracted from liver with vitamin E and with
            commercially purified ubiquinone. Besides using the pure substances, I decided to combine vitamin E with
            ubiquinone for another test spot. As soon as I combined the two oils, their amber and orange colors turned
            to an inky, greenish black color. I tested both bacterial and mammalian ubiquinone, and benzoquinone, and
            they all produced similar colors with vitamin E. When I ran the solvent up the paper, the vitamin E and the
            ubiquinone traveled at slightly different speeds. The black spot, containing the mixture, also moved, but
            each substance moved at its own speed, and as the materials separated, their original lighter colors
            reappeared. Charge-transfer bonds, which characteristically produce dark colors, are very weak bonds. I
            think this must have been that kind of bond. Years later, I tried to repeat the experiment, using
            "ubiquinone" from various capsules that were sold for medical use. Instead of the waxy yellow-orange
            material I had used before, these capsules contained a liquid oil with a somewhat yellow color. Very likely,
            the ubiquinone was dissolved in vegetable oil. At the time, I was puzzled that the color reaction didn't
            occur, but later I realized that a solvent containing double bonds (e.g., soy oil or other oil containing
            PUFA) would very likely prevent the close association between vitamin E and ubiquinone which is necessary
            for charge-transfer to occur. Since I think Koch and Szent-Gyorgyi were right in believing that electronic
            activation is the most important feature of the living state, I think the very specific electronic
            interaction between vitamin E and ubiquinone must play an important role in the respiratory function of
            ubiquinone. Ubiquinone is known to be a part of the electron transport chain which can leak electrons, so
            this might be one of the ways in which vitamin E can prevent the formation of toxic free-radicals. If it can
            prevent the "leakage" of electrons, then this in itself would improve respiratory efficiency. If unsaturated
            oils interfere with this very specific but delicate bond, then this could explain, at least partly, their
            toxicity for mitochondria. ["Electron leak" reference: B. Halliwell, in <em>Age Pigments</em> (R. S. Sohal,
            ed.), pp. 1-62, Elsevier, Amsterdam, 1981.]

            <strong>Osteoporosis, aging, tissue renewal, and product science</strong>
        </p>
        <p>
            The incidence of osteoporosis, like obesity, has been increasing in recent decades. The number of hip
            fractures in many countries has doubled in the last 30 or 40 years (Bergstrom, et al., 2009). An exception
            to that trend was Australia in the period between 2001 and 2006, where the annual incidence of hip fractures
            in women over 60 years old decreased by 28.3%. During those years, the number of prescriptions for "hormone
            replacement therapy" decreased by 54.6%, and the number of prescriptions for bisphosphonate increased by
            245%. The publication of the Women's Health Initiative results in 2002 (showing that the Prem-Pro treatment
            caused breast cancer, heart attacks, and dementia), led to a great decrease in the use of estrogen
            treatments everywhere. After the FDA approved estrogen's use in 1972 for the prevention of osteoporosis the
            number of women using it increased greatly, and by 1994, 44% of women in the US had used it. After the WHI
            results were published, the number of prescriptions for "HRT" fell by more than half, and following that
            decrease in estrogen sales, the incidence of breast cancer decreased by 9% in women between the ages of 50
            and 54.With the incidence of hip fractures increasing while the percentage of women using estrogen was
            increasing, it seems likely that there is something wrong with the theory that osteoporosis is caused by an
            estrogen deficiency. That theory was derived from the theory that menopause was the consequence of ovarian
            failure, resulting from the failure to ovulate and produce estrogen when the supply of eggs was depleted.
            The theory was never more than an ideological preference, but the estrogen industry saw it as an opportunity
            to create a huge market.There are many studies that seem to imply that the greater incidence of osteoporotic
            fractures among women is the result of their exposure to estrogen during their reproductive years. This
            would be analogous to the understanding that it is the cumulative exposure to estrogen that ages the nerves
            in the hypothalamus that control the cyclic release of the gonadotropic hormones, causing the
            menopause.<strong>. . . the nature of science itself changed around the middle of the last century, becoming
                product and disease oriented, so that now relatively few people are continuing to study bones
                objectively.</strong>Animal studies show that estrogen stunts growth, including bone growth. The high
            estrogen levels in girls' teen years and early twenties accounts for the fact that women's bones are lighter
            than men's. In rat studies, treatment with estrogen was found to enlarge the space between the jawbone and
            the teeth, which is a factor in periodontal disease (Elzay, 1964). Teeth are very similar to bones, so it's
            interesting that treating male or female rats with estrogen increases their incidence of tooth decay, and
            removing their gonads was found to decrease the incidence (Muhler and Shafer, 1952). Supplementing them with
            thyroid hormone decreased the incidence of cavities in both males and females (Bixler, et al., 1957).One of
            the "estrogen receptors" appears to actively contribute to bone loss (Windahl, et al., 1999, 2001). Studies
            in dogs following the removal of their ovaries found that there was an increase of bone remodeling and bone
            formation rate in the first month, followed by a few months of slowed bone formation, but that by 10 months
            after the surgery the bones had returned to their normal remodeling rate, and that "at no time was a
            significant reduction in bone volume detected" (Boyce, et al., 1990). With the removal of the ovaries, the
            production of progesterone as well as estrogen is affected, but the adrenal glands and other tissues can
            produce those hormones.Until the influence of the estrogen industry overwhelmed it, ordinary science was
            studying bone development in comprehensive ways, understanding its biological roles and the influences of
            the environment on it. But the nature of science itself changed around the middle of the last century,
            becoming product and disease oriented, so that now relatively few people are continuing to study bones
            objectively.The outstanding physical-chemical property of bone is that it is a reservoir-buffer of carbon
            dioxide, able to bind huge amounts of the gas into its structure.When carbon dioxide increases in the
            bloodstream it is at first absorbed rapidly by the bones, and if the blood level of CO2 is kept high day
            after day, the rate of absorption gradually slows down, but in experiments that have continued for several
            weeks the bones were still slowly absorbing more carbon dioxide; the absorption curve seems to be
            asymptotic. When people move to or from high altitudes, their bones appear to continue adapting to the
            different gas pressures for years. A reduction of atmospheric pressure (which allows the tissues to retain
            more carbon dioxide) helps to reduce the calcium loss caused by immobility (Litovka and Berezovs'ka, 2003;
            Berezovs'kyi, et al., 2000), and promotes the healing of damaged bone (Bouletreau, et al., 2002). Ultrasound
            treatment, which accelerates bone healing, stimulates processes similar to reduced oxygen supply (Tang, et
            al., 2007). The mineral in newly formed bone is calcium carbonate, and this is gradually changed to include
            a large amount of calcium phosphate. Besides forming part of the mineral, carbon dioxide is also
            incorporated into a protein (in a process requiring vitamin K), in a process that causes this protein,
            osteocalcin, to bind calcium. The osteocalcin protein is firmly bonded to a collagen molecule. Collagen
            forms about 30% of the mass of bone; several percent of the bone consists of other organic molecules,
            including osteocalcin, and the rest of the mass of the bone consists of mineral.Thyroid hormone is essential
            for forming carbon dioxide. In the early 1940s, experimental rabbits were fed their standard diet, with the
            addition of 1% desiccated thyroid gland, which would be equivalent to about 150 grains of Armour thyroid for
            a person. They became extremely hypermetabolic, and couldn't eat enough to meet their nutritional needs for
            growth and tissue maintenance. When they died, all of their tissues weighed much less than those of animals
            that hadn't received the toxic dose of thyroid, except for their bones, which were larger than normal.
            Experiments with the thin skull bones of mice have shown that the active thyroid hormone, T3, increases the
            formation of bone. To increase cellular respiration and carbon dioxide production, T3 increases the activity
            of the enzyme cytochrome oxidase, which uses copper as a co-factor. Increased thyroid activity increases the
            absorption of copper from foods.There is an inherited condition in humans, called osteopetrosis or marble
            bone disease, caused by lack of a carbonic anhydrase enzyme, which causes them to retain a very high level
            of carbon dioxide in their tissues. Using a chemical that inhibits carbonic anhydrase, such as the diuretic
            acetazolamide, a similar condition can be produced in animals. Acetazolamide inhibits the bone resorbing
            actions of parathyroid hormone, including lactic acid formation and the release of the lysosomal enzyme,
            beta-glucuronidase (Hall and Kenny, 1987). While lactic acidosis causes bone loss, acidosis caused by
            increased carbonic acid doesn't; low bicarbonate in the body fluids seems to remove carbonate from the bone
            (Bushinsky, et al., 1993), and also mineral phosphates (Bushinsky, et al., 2003). The parathyroid hormone,
            which removes calcium from bone, causes lactic acid to be formed by bone cells (Nijweide, et al., 1981;
            Lafeber, et al., 1986). Lactic acid produced by intense exercise causes calcium loss from bone (Ashizawa, et
            al., 1997), and sodium bicarbonate increases calcium retention by bone. Vitamin K2 (Yamaguchi, et al., 2003)
            blocks the removal of calcium from bone caused by parathyroid hormone and prostaglandin E2, by completely
            blocking their stimulation of lactic acid production by bone tissues. Aspirin, which, like vitamin K,
            supports cell respiration and inhibits lactic acid formation, also favors bone calcification. Vitamin K2
            stimulates the formation of two important bone proteins, osteocalcin and osteonectin (Bunyaratavej, et al.,
            2009), and reduces the activity of estrogen by oxidizing estradiol (Otsuka, et al, 2005).The formation of
            eggshell, which is mostly calcium carbonate, is analogous to the early stage of bone formation. In hot
            weather, when chickens pant and lower their carbon dioxide, they form thin shells. A sodium bicarbonate
            supplement improves the quality of the eggshell (Balnave and Muheereza, 1997; Makled and Charles, 1987).
            Chickens that habitually lay eggs with thinner shells have lower blood bicarbonate than those that lay thick
            shelled eggs (Wideman and Buss, 1985). One of the arguments for stopping the sale of DDT in the US was that
            it was threatening to cause extinction of various species of bird because it caused them to lay eggs with
            very weak shells. Several other synthetic estrogenic substances, ethynylestradiol, lindane, PCBs, cause
            eggshell thinning, partly by altering carbonic anhydrase activity (Holm, et al, 2006). Estrogen and
            serotonin activate carbonic anhydrase in some tissues, progesterone tends to inhibit it. DDE, a metabolite
            of DDT, reduces medullary bone formation in birds (Oestricher, et al., 1971) and bone mineral density in men
            (Glynn, et al., 2000). Among its estrogenic effects, DDE increases prolactin (Watson, et al., 2007); one
            form of DDT inhibits progesterone synthesis and increases estrogen (Wojtowics, et al., 2007)In youth, the
            mineralization of the collagen framework is slightly lower than in maturity, and the bones are more
            flexible. With aging, the mineralization increases progressively, and the proportion of collagen decreases
            slightly, and the bones become increasingly brittle. (Rogers, et al., 1952; Mbuyi-Muamba, et al., 1987).
            Collagen is a major part of the extracellular substance everywhere in the body, and its concentration
            increases with aging in the non-calcified tissues. There is considerable renewal and modification of
            collagen, as new molecules are formed and old molecules broken down, but its average structure changes with
            aging, becomes less soluble and more rigid, as the result of chemical cross-links formed between molecules.
            These cross-links are involved in regulating the differentiation of bone cells (Turecek, et al., 2008).
            Recently (August 2, 2011), Deasey et al., have published evidence showing that cross-linking is required for
            bone mineralization (2011).<strong>The outstanding physical-chemical property of bone is that it is a
                reservoir-buffer of carbon dioxide, able to bind huge amounts of the gas into its structure.</strong
            >Around 1950, Fritz Verzar began studying the changes of collagen that occur with aging, and his work led to
            the "collagen theory of aging." He showed that older, stiffer, less elastic tendons have a higher "melting"
            or contracting temperature than young tendons. (This effect is responsible for the curling of a piece of
            meat when it is frying.) Verzar and his colleagues investigated the effects of hormonal treatments on the
            aging of rat collagen, especially in their tail tendons. They found that estrogen treatment increased the
            stiffness and the melting temperature of collagenous tissues. While estrogen increased the cross-linking
            with aging, removing the pituitary gland was found to retard the aging. Later, the cross-linking enzymes
            transglutaminase and lysyl oxidase, which are induced by estrogen, were found to be a major factor in the
            cross-linking of collagen and other molecules.When estrogen was found to age the connective tissues, it was
            assumed that continual breeding during an animal's life-time, greatly increasing the total exposure of the
            tissues to estrogen, would increase the aged rigidity of the connective tissues, but these animals were
            found to have less rigid tissues. During pregnancy other hormones, especially progesterone, were also
            increased, and it was suggested that this reversed the effects of aging and estrogen. Since most people had
            believed that frequent pregnancies would cause a woman to age more rapidly, a large survey of records was
            done, to compare the longevity of women with the number of pregnancies. It was found, in the very extensive
            Hungarian records, that life-span was increased in proportion to the number of pregnancies.Despite these
            very interesting results in the 1950s and 1960s, the growing influence of the estrogen industry changed the
            direction of aging research, favoring the belief that decreasing estrogen accelerated the deterioration of
            tissues in aging, and the popularity of Denham Harman's "free radical theory of aging" led many people to
            assume that random reactions produced by lipid peroxidation were responsible for most of the cross-linking,
            and that theory was gradually replaced by the "glycation" theory of aging, in which sugar molecules break
            down and form the cross-links, by random, non-enzymic processes. Estrogen's role in aging was completely
            by-passed.The meat industry is interested in reducing the toughness of meat, by influencing the nature of
            the collagen in muscle. Castrated animals were found to produce meat that was tenderer than that of intact
            males. When castrated animals were treated with testosterone, the amount of collagen was increased, making
            the meat tougher. But when dihydrotestoserone, which can't be converted to estrogen was used, the meat
            didn't become tough. Treatment with estrogen produced the same increase of collagen as treatment with
            testosterone, showing that testosterone's effect was mainly the result of its conversion to estrogen
            (Miller, et al., 1990).In the 1960s and '70s the estrogen industry was looking for ways to build on the
            knowledge that in puberty estrogen is responsible for accelerating the calcification of the growth plate at
            the ends of the long bones, and to find a rationale for selling estrogen to all women concerned with the
            problems of aging. As bone metabolism was investigated, two kinds of cell were found to be active in
            constantly remodeling the bone structure: Osteoclasts (breaking it down), and osteoblasts (building new
            bone). Estrogen was found to slow the actions of the osteoclasts, so the idea that it would delay
            osteoporosis became the basis for a huge new marketing campaign. Slowing bone metabolism became the focus.
            Although estrogen was known to increase prolactin, and prolactin was known to accelerate bone loss, nearly
            all publications began to focus on substances in the blood or urine that corresponded to the rate of bone
            turnover, with the implication that increasing bone turnover would correspond to a net loss of bone.This was
            the context in which, during the 1980s, articles about thyroxine's role in causing osteoporosis began to
            appear. The thyroid hormone supports bone renewal, and increases indicators of bone breakdown in the blood
            and urine. If estrogen's use was to be justified by slowing bone turnover, then the effects of thyroid,
            accelerating bone turnover, should be interpreted as evidence of bone destruction.A basic problem with many
            of the publications on thyroid and bone loss was that they were talking about an unphysiological medical
            practice (prescribing the pre-hormone, thyroxine), which frequently failed to improve thyroid function, and
            could even make it worse, by lowering the amount of T3 in the tissues.Later, it was noticed that high TSH
            was associated with the signs of lower bone turnover. TSH rises when there is less thyroid hormone, but
            (after the recombinant TSH became available for medical use) a few publications argued that it was the TSH
            itself, rather than the absence of thyroid hormone, that was "protecting" the bones (lowering the evidence
            of bone turnover). The doctrine that had been developed to support estrogen therapy was now used to oppose
            thyroid therapy. Keeping the TSH high would slow bone turnover. Working in this cultural context, genetic
            engineers at Amgen identified a protein that inhibited the formation of osteoclast cells, and slowed bone
            metabolism. It was suggested that it was responsible for estrogen's suppression of the osteoclasts, and many
            publications appeared showing that it was increased by estrogen. It was named "osteoprotegerin," meaning
            "the bone protecting protein." Prolactin increases osteoprotegerin (OPG), reducing bone resorption just as
            estrogen does. Serotonin also increases OPG, and it turns out that OPG is elevated in all of the
            pathological conditions associated with high serotonin, including cancer, pulmonary artery hypertension,
            vascular calcification, and even bone loss.While Arthur Everitt, Verzar, and others were studying the
            effects of the rat's pituitary (and other glands) on collagen, W. D. Denckla investigated the effects of
            reproductive hormones and pituitary removal in a wide variety of animals, including fish and mollusks. He
            had noticed that reproduction in various species (e.g., salmon) was quickly followed by rapid aging and
            death. Removing the pituitary gland (or its equivalent) and providing thyroid hormone, he found that animals
            lacking the pituitary lived much longer than intact animals, and maintained a high metabolic rate. Making
            extracts of pituitary glands, he found a fraction (closely related to prolactin and growth hormone) that
            suppressed tissue oxygen consumption, and accelerated the degenerative changes of aging.Aging, estrogen,
            cortisol, and a variety of stresses, including radiation and lipid peroxidation, chemically alter collagen,
            producing cross-links that increase its rigidity, and affect the way it binds minerals. The cross-linking
            enzymes induced by estrogen are involved in the normal maturation of bone collagen, and at puberty when
            estrogen increases, bone growth is slowed, as the cross-linking and mineralization are accelerated. With
            aging and the accumulation of heavy metals and polyunsaturated fats, random oxidative processes increase the
            cross-linking. In bones, the relatively large masses of cartilage absorb oxygen and nutrients slowly, so
            internally the amount of oxygen is very limited, about 1/5 as much as at the surface, and this low oxygen
            tension is an important factor in regulating growth, differentiation, cross-linking, and calcification,
            maintaining bone integrity. But in blood vessels the connective tissues are abundantly supplied with oxygen
            and nutrients; this is normally a factor regulating the production of collagen and its cross-linking, and
            preventing calcification. When the factors promoting collagen synthesis and maturation are increased
            systemically, with aging and stress, the excess cross-linking slows the biological renewal process in bones,
            but in blood vessels the same processes creating excess cross-linking initiate a calcification process,
            involving the various factors that in youth are responsible for normal maturation of bone.Prolactin, like
            estrogen, interferes with thyroid function and oxygen consumption (Wade, et al., 1986; Strizhkov, 1991;
            Spatling, et al., 1982). Many years ago, repeated lactation was considered to cause osteoporosis and loss of
            teeth, and prolactin, which mobilizes calcium from bones for the production of milk, was recognized as an
            important factor in bone loss. Drugs that increase prolactin were found to cause osteoporosis. In the 40
            years since the drug industry began its intense promotion of estrogen to prevent and treat osteoporosis,
            there has been very little attention to the fact that estrogen increases prolactin, which contributes to
            osteoporosis, but some people (e.g., Horner, 2009) have noticed that oral contraceptives and menopausal
            hormone treatments have damaged the bones of the inner ear, causing otosclerosis and impaired hearing, and
            have suggested that prolactin mediates the effect.A few years ago, the "serotonin reuptake inhibitor"
            antidepressants, already known to increase prolactin by increasing the effects of serotonin, were found to
            be causing osteoporosis after prolonged use. Estrogen increases serotonin, which besides promoting the
            secretion of prolactin, also stimulates the production of parathyroid hormone and cortisol, both of which
            remove calcium from bone, and contribute to the calcification of blood vessels. The association between
            weakened bones and hardened arteries is now widely recognized, but researchers are being careful to avoid
            investigating any mechanisms that could affect sales of important drug products, especially estrogen and
            antidepressants.Following the recognition that the SSRI drugs were causing osteoporosis, it was discovered
            that the serotonin produced in the intestine causes bone loss, and that inhibiting intestinal serotonin
            synthesis would stop bone loss and produce a bone building anabolic effect (Inose, et al., 2011). One group
            that had been concentrating on the interactions of genes commented that, recognizing the effects of
            intestinal serotonin, they had suddenly become aware of "whole organism physiology" (Karsenty and Gershon,
            2011).In previous newsletters I have talked about the ability of intestinal irritation and the associated
            increase of serotonin to cause headaches, asthma, coughing, heart and blood vessel disease, muscular
            dystrophy, flu-like symptoms, arthritis, inflammation of muscles and nerves, depression, and inflammatory
            brain diseases. With the new recognition that serotonin is a basic cause of osteoporosis, intestinal health
            becomes a major issue in aging research.The protein that inhibits intestinal formation of serotonin is the
            low density lipoprotein receptor-related protein. This seems likely to have something to do with the fact
            that "low" HDL is associated with better bones. A low level of LDL is associated with increased vertebral
            fractures (Kaji, et al., 2010).Cartilage synthesis and turnover are highest at night. It is inhibited by
            metabolic acidosis (increased lactic acid), but not by respiratory acidosis (CO2) (Bushinsky, 1995). Since
            most calcium is lost from bone during the night (Eastell, et al., 1992; even in children: DeSanto, et al.,
            1988) in association with the nocturnal rise of the catabolic substances, such as free fatty acids,
            cortisol, prolactin, PTH, and adrenalin, things which minimize the nocturnal stress can decrease the bone
            turnover. These include calcium (Blumsohn, et al., 1994) and sugar. Catabolic substances and processes
            increase with aging, especially at night. Babies grow most during the night when bone turnover is high, and
            even a daytime nap accelerates collagen turnover (Lutchman, et al., 1998). Discussions about whether a
            certain person's osteoporosis is "menopausal osteoporosis" or "senile osteoporosis" have neglected the
            possibility that osteoporosis doesn't begin in either menopause or old age, but that it is the result of
            life-long developmental processes that interact with all the factors that are involved in aging. The fact
            that the collagen content of old bone is lower than in young bone (as a percentage of bone weight) shows
            that the problem in osteoporosis isn't a lack of calcification, it's a deficiency of tissue renewal,
            parallel to sarcopenia, the decrease of muscle mass with aging. Systemically decreased tissue renewal would
            account for the association of bone loss with other processes such as male baldness (Morton, et al., 2007)
            and Alzheimer's disease (Zhou, et al., 2011, Duthie, et al., 2011).A high level of respiratory energy
            production that characterizes young life is needed for tissue renewal. The accumulation of factors that
            impair mitochondrial respiration leads to increasing production of stress factors, that are needed for
            survival when the organism isn't able to simply produce energetic new tissue as needed. Continually
            resorting to these substances progressively reshapes the organism, but the investment in short-term
            survival, without eliminating the problematic factors, tends to exacerbate the basic energy problem. This
            seems to be the reason that Denckla's animals, deprived of their pituitary glands, but provided with thyroid
            hormone, lived so long: they weren't able to mobilize the multiple defenses that reduce the mitochondria's
            respiratory energy production. Several things that the geneticists would never be able to fit into their
            schemes of "bone regulatory molecules" such as OPG, growth hormone, parathyroid hormone, and estrogen, fit
            neatly with the idea that bone health is maintained by respiratory energy and tissue renewal, under the
            influence of thyroid hormone. For example, adrenaline, which is increased by stress, aging, and
            hypothyroidism (and in many cases by estrogen), causes bone loss. Even the bone loss caused by immobility
            can be blocked by an adrenaline blocker such as propranolol. (The stress of immobility also famously
            increases serotonin.) Adrenaline tends to decrease carbon dioxide and increase lactic acid, and it strongly
            increases parathyroid hormone (Ljunhgall S, et al., 1984). Calcium activates mitochondrial respiration, and
            lowers adrenaline (Luft, et al., 1988), parathyroid hormone (Ohgitani, et al., 1997), and prolactin (Kruse
            and Kracht, 1981). Copper, which is the co-factor for the cytochrome C oxidase enzyme, activated by thyroid,
            is essential for bone formation and maintenance, and is consistently deficient in osteoporosis. Thyroid
            hormone increases the body's ability to assimilate copper. Aspirin, which stimulates bone formation, has
            other thyroid-like actions, including activation of mitochondrial respiration and energy production, with an
            increase of cytochrome C oxidase (Cai, et al., 1996), and it lowers serotonin (Shen, et al., 2011). It also
            apparently protects against calcification of the soft tissues, (Vasudev, et al., 2000), though there has
            been surprisingly little investigation of that. "Aspirin can promote trabecular bone remodeling, improve
            three-dimensional structure of trabecular bone and increase bone density of cancellous in osteoporotic rats
            by stimulating bone formation. It may become a new drug for the treatment of osteoporosis" (Chen, et al.,
            2011).A wide range of inflammatory mediators that accelerate inflammation and bone loss also inhibit thyroid
            function. People who ate more polyunsaturated fat, which inhibits thyroid and oxidative metabolism, were
            several times more likely to have osteoporotic fractures (that is, essentially spontaneous fractures) than
            people who ate the least (Martinez-Ramirez, et al., 2007). Arachidonic acid stimulates prolactin secretion,
            and prolactin acts on the thyroid gland to decrease its activity, and on other tissues to increase their
            glycolysis (with lactate production), while decreasing oxidative metabolism (Spatling, et al., 1982;
            Strizhkov, 1991). Living at high altitude, which strengthens bones, increases thyroid activity and decreases
            prolactin (Richalet, et al., 2010) and parathyroid hormone (Khan, et al., 1996). It lowers free fatty acids,
            which lower bone mass by reducing bone formation and increasing bone resorption (Chen, et al., 2010). In
            menopausal women, polyunsaturated fatty acids and even monounsaturated fats are associated with bone loss,
            fruit and vegetable consumption protects against bone loss (Macdonald, et al., 2004).While it's very
            interesting that the drug propranol which blocks adrenaline, and drugs that block serotonin formation, have
            bone protective and restorative effects, they also have undesirable side effects. Food choices that optimize
            oxidative metabolism are the safest, as well as the most economical, way to approach the problem of
            osteoporosis and other degenerative changes. A person can easily perceive changes in appetite, quality of
            sleep, changes in skin, hair, and mood, etc., but blood tests could be used to confirm that the right
            choices were being made. Tests for vitamin D, parathyroid hormone, free fatty acids, and CO2/bicarbonate, as
            well as the hormones, can be helpful, if a person isn't sure whether their diet, sunlight exposure, and
            thyroid supplementation is adequate. The popular medical understanding of the organism is based on a
            mechanistic view of causality, in which genes have a central role, causing things to develop and function in
            certain ways, and that hormones and drugs can cause genes to increase or decrease their activity. Genes that
            build bones can be activated by one substance, and genes that tear down bones can be inhibited by another
            substance. The "osteoprotegerin" story illustrates the problem with that kind of thinking. Vernadsky's
            description of an organism as a "whirlwind of atoms" is probably a better way to think of how "causality"
            works. The moving air in a whirlwind forms a self-intensifying system, with the motion reducing the
            pressure, causing more air to be drawn into the system. The atoms moving in coordination aren't acting as
            separate things, but as parts in a larger thing. The way in which increased metabolism in the bones acts
            favorably on the metabolism of kidneys, blood vessels, lungs, liver, digestive system, etc., which in turn
            favors the bones' renewal, is analogous to the tendency of a whirlwind to intensify as long as there is a
            source of energy. <strong>The intensity of oxidative metabolism is the basic factor that permits continuing
                coordination of activity, and the harmonious renewal of all the components of the organism.</strong>

            During pregnancy, a woman's ability to retain dietary calcium and iron increases, and the baby seems to be
            susceptible to overloading. A normal baby doesn't need dietary iron for several months, as it uses the iron
            stored in its tissue, and recently it has been reported that normal fetuses and babies may have calcified
            pituitary glands. Pituitary cell death is sometimes seen with the concretions. (Groisman, et al.)
            Presumably, the calcification is resorbed as the baby grows. This is reminiscent of the "age pigment" that
            can be found in newborns, representing fetal stress from hypoxia, since that too disappears shortly after
            birth. Iron overload, age pigment, and calcification of soft tissues are so commonly associated with old
            age, that it is important to recognize that the same cluster occurs at the other extreme of (young) age, and
            that respiratory limitations characterize both of these periods of life.

            Calcium is probably the most popular element in physiological research, since it functions as a regulatory
            trigger in many cell processes, including cell stimulation and cell death. Its tendency to be deposited with
            iron in damaged tissue has often been mentioned. In hot weather, chickens pant to cool themselves, and this
            can lead to the production of thin egg shells. Carbonated water provides enough carbon dioxide to replace
            that lost in panting, and allows normal calcification of the shells. [Science 82, May, 1982] The deposition
            of calcium is the last phase of the "tertiary coat" of the egg, to which the oviduct glands successively add
            albumin, "egg membrane," and the shell, containing matrix proteins (including some albumin; Hincke, 1995)
            and calcium crystals. Albumin is the best understood of these layers, but it is still complex and
            mysterious; its unusual affinity for metal ions has invited comparisons with proteins of the immune system.
            It is known to be able to bind iron strongly, and this is considered to have an "immunological" function,
            preventing the invasion of organisms that depend on iron. Maria de Sousa ("Iron and the lymphomyeloid
            system: A growing knowledge," Iron in Immunity, Cancer and Inflammation, ed. by M. de Sousa and J. H. Brock,
            Wiley &amp; Sons, 1989) has argued that the oxygen delivery system and the immune system evolved together,
            recycling iron in a tightly controlled system.

            The role of macrophages in the massive turnover of hemoglobin, and as osteoclasts, gives us a perspective in
            which iron and calcium are handled in analogous ways. Mechnikov's view of the immune system, growing from
            his observations of the "phagocytes," similarly gave it a central role in the organism as a form-giving/
            nutrition-related process. In a family with "marble-bone disease," or osteopetrosis, it was found that their
            red blood cells lacked one form of the carbonic anhydrase enzyme, and that as a result, their body fluids
            retained abnormally high concentrations of carbon dioxide. Until these people were studied, it had been
            assumed that an excess of carbon dioxide would have the opposite effect, dissolving bones and causing
            osteoporosis or osteopenia, instead of osteopetrosis. The thyroid hormone is responsible for the carbon
            dioxide produced in respiration. Chronic hypothyroidism causes osteopenia, and in this connection, it is
            significant that women (as a result of estrogen's effects on the thyroid) are much more likely than men to
            be hypothyroid, and that, relative to men, women in general are "osteopenic," that is, they have more
            delicate skeletons than men do.
        </p>

        <p>
            In an experiment, rats were given a standard diet, to which had been added 1% Armour thyroid, that is, they
            were made extremely hyperthyroid. Since their diet was inadequate (later experiments showed that this amount
            of thyroid didn't cause growth retardation when liver was added to the diet) for their high metabolic rate,
            they died prematurely, in an apparently undernourished state, weighing much less than normal rats. Their
            bones, however, were larger and heavier than the bones of normal rats. A few incompetent medical "studies"
            have made people fear that "taking thyroid can cause osteoporosis." Recognizing that hypothyroid women are
            likely to have small bones and excessive cortisol production, the inadequate treatment of hypothyroidism
            with thyroxin (the thyroid-suppressive precursor material), is likely to be associated with relative
            osteoporosis, simply because it doesn't correct hypothyroidism. Similar misinterpretations have led people
            to see an association between "thyroid use" (generally thyroxin) and breast cancer--hypothyroid women are
            likely to have cancer, osteoporosis, obesity, etc., and are also likely to have been inadequately treated
            for hypothyroidism. T3, the active form of thyroid hormone, does contribute to bone formation. (For example,
            M. Alini, et al.)
        </p>
        <p>
            Around the same time (early 1940s) that the effects of thyroid on bone development were being demonstrated,
            progesterone was found to prevent age-related changes in bones, and "excessive" seeming doses of thyroid
            were found to prevent age-related joint diseases in rats.
        </p>
        <p>
            A logical course of events, building on these and subsequent discoveries, would have been to observe that
            the glucocorticoids cause a negative calcium balance, leading to osteoporosis, and that thyroid and
            progesterone oppose those hormones, protecting against osteoporosis. But the drug industry had discovered
            the profits in estrogen ("the female hormone") and the cortisone-class of drugs. Estrogen was promoted to
            prevent miscarriages, to stop girls (and boys) from growing too tall, to cure prostate and breast cancer, to
            remedy baldness, and 200 other absurdities. As all of those frauds gradually became untenable, even in the
            commercial medical culture, the estrogen industry began to concentrate on osteoporosis and femininity. Heart
            disease and Alzheimer's disease back those up.
        </p>
        <p>
            "If estrogen causes arthritis, prescribe prednisone for the inflammation. If prednisone causes osteoporosis,
            increase the dose of estrogen to retard the bone-loss. People are tough, and physiological therapies aren't
            very profitable."

            Fifteen years ago I noted in a newsletter that hip fractures most often occur in frail, underweight old
            women, and that heavier, more robust women seem to be able to bear more weight with less risk of fracture.
            Although I hadn't read it at the time, a 1980 article (Weiss, et al.) compared patients with a broken hip or
            arm with a control group made up of hospitalized orthopedic patients with problems other than hip or arm
            fractures. The fracture cases' weight averaged 19 pounds lighter than that of the other patients. They were
            more than 3.6 times as likely to be alcoholic or epileptic. It would be fair to describe them as a less
            robust group.
        </p>
        <p>
            Since the use of estrogen has become so common in the U.S., it is reasonable to ask whether the incidence of
            hip fractures in women over 70 has declined in recent decades. If estrogen protects against hip fractures,
            then we should see a large decrease in their incidence in the relevant population.
        </p>
        <p>
            Hip fractures, like cancer, strokes, and heart disease, are strongly associated with old age. Because of the
            baby-boom, 1945 to 1960, our population has a bulge, a disproportion in people between the ages of 35 and
            50, and those older. Increasingly, we will be exposed to publicity about the declining incidence of disease,
            fraudulently derived from the actually declining proportion of old people. For example, analyzing claims
            based on the pretense that the population bulge doesn't exist, I have seen great publicity given to studies
            that would imply that our life-expectancy is now 100 years, or more.
        </p>
        <p>
            Comparing the number of hip fractures, per 1000 75 year old women, in 1996, with the rate in 1950, we would
            have a basis for judging whether estrogen is having the effect claimed for it.
        </p>
        <p>
            The x-ray data seem to convince many people estrogen is improving bone health, by comparing measurements in
            the same person before and after treatment. Does estrogen cause water retention? Yes. Does tissue water
            content increase measured bone density? Yes. Are patients informed that their "bone scans" don't have a
            scientific basis? No. The calcification of soft tissues under the influence of estrogen must also be taken
            into account in interpreting x-ray evidence. (Hoshino, 1996) Granted that woman who are overweight have
            fewer hip fractures (and more cancer and diabetes), what factors are involved? Insulin is the main factor
            promoting fat storage, and it is anabolic for bone. (Rude and Singer, "Hormonal modifiers of mineral
            metabolism.") The greatest decrease in bone mass resulting from insulin deficiency was seen in white
            females, and after five years of insulin treatment, there was a lower incidence of decreased bone mass
            (Rosenbloom, et al., 1977). McNair, et al. (1978 and 1979) found that the loss of bone mass coincided with
            the onset of clinical diabetes. Since excess cortisol can cause both high blood sugar and bone loss, when
            diabetes is defined on the basis of high blood sugar, it will often involve high blood sugar caused by
            excess cortisol, and there will be calcium loss. Elsewhere, I have pointed out some of the similarities
            between menopause and Cushing's syndrome; a deficiency of thyroid and progesterone can account for many of
            these changes. Nencioni and Polvani have observed the onset of progesterone deficiency coinciding with bone
            loss, and have emphasized the importance of progesterone's antagonism to cortisol.
        </p>

        <p>
            Johnston (1979) found that progesterone (but not estrone, estradiol, testosterone, or androstenedione) was
            significantly lower in those losing bone mass most rapidly.
        </p>
        <p>
            Around the age of 50, when bone loss is increasing, progesterone and thyroid are likely to be deficient, and
            cortisol and prolactin are likely to be increased. Prolactin contributes directly to bone loss, and is
            likely to be one of the factors that contributes to decreased progesterone production.
        </p>
        <p>
            Estrogen tends to cause increased secretion of prolactin and the glucocorticoids, which cause bone loss, but
            it also promotes insulin secretion, which tends to prevent bone loss. All of these factors are associated
            with increased cancer risk.
        </p>
        <p>
            Thyroid and progesterone, unlike estrogen, stimulate bone-building, and are associated with a decreased risk
            of cancer. It seems sensible to use thyroid and progesterone for their general anti-degenerative effects,
            protecting the bones, joints, brain, immune system, heart, blood vessels, breasts, etc.
        </p>
        <p>
            But the issue of calcification/decalcification is so general, we mustn't lose interest just because the
            practical problem of osteoporosis is approaching solution.
        </p>

        <p>
            For example, healthy high energy metabolism requires the exclusion of most calcium from cells, and when
            calcium enters the stimulated or deenergized cell, it is likely to trigger a series of reactions that lower
            energy production, interfering with oxidative metabolism. During aging, both calcium and iron tend to
            accumulate and they both seem to have an affinity for similar locations, and they both tend to displace
            copper. (Compare K. Sato, et al., on the calcification of copper-containing paints.) Elastin is a protein,
            the units of which are probably bound together by copper atoms. In old age, elastin is one of the first
            substances to calcify, for example in the elastic layers of arteries, causing them to lose elasticity, and
            to harden into almost bone-like tubes. In the heart and kidneys, the mitochondria (rich in copper-enzymes)
            are often the location showing the earliest calcification, for example when magnesium is deficient.
        </p>
        <p>
            Obviously, certain proteins have higher than average affinity for copper, iron, and calcium. For example,
            egg-white's unusual behavior with copper can be seen if you make a meringue in a copper pan--the froth is
            unusually firm. My guess is that copper atoms bind the protein molecules into relatively elastic systems. In
            many systems, calcium forms the link between adhesive proteins.
        </p>
        <p>
            In brain degeneration, the regions that sometimes accumulate aluminum, will accumulate other metals instead,
            if they predominate in the environment; calcium is found in this part of the brain in some of the Pacific
            regions studied by Gajdusek. Certain cells in the brain used to be called "metalophils," because they could
            be stained intensely with silver and other metals; I suppose these are part of the immune system, handling
            iron as described by Maria de Sousa. Macrophages have been proposed as an important factor in producing
            atherosclerotic plaques (Carpenter, et al.). There is evidence that they (and not smooth muscle cells) are
            the characteristic foam cells, and their conversion of polyunsaturated oils into age pigment accounts for
            the depletion of those fats in the plaques. The same evidence could be interpreted as a defensive reaction,
            binding iron and destroying unsaturated fatty acids, and by this detoxifying action, possibly protecting
            against calcification and destruction of elastin. (This isn't the first suggestion that atherosclerosis
            might represent a protective process; see S. M. Plotnikov, et al., 1994.)
        </p>
        <p>
            Since carbon dioxide and bicarbonate are formed in the mitochondria, it is reasonable to suppose that the
            steady outward flow of the bicarbonate anion would facilitate the elimination of calcium from the
            mitochondria. Since damaged mitochondria are known to start the process of pathological calcification in the
            heart and kidneys, it probably occurs in other tissues that are respiratorily stressed. And if healthy
            respiration, producing carbon dioxide, is needed to keep calcium outside the cell, an efficient defense
            system could also facilitate the deposition of calcium in suitable places--depending on specific protein
            binding. The over-grown bones in the hyperthyroid rats and the women with osteopetrosis suggest that an
            abundance of carbon dioxide facilitates bone formation. Since no ordinary inorganic process of
            precipitation/crystallization has been identified that could account for this, we should consider the
            possibility that the protein matrix is regulated in a way that promotes (or resists) calcification. The
            affinity of carbon dioxide for the amine groups on proteins (as in the formation of carbamino hemoglobin,
            which changes the shape of the protein) could change the affinity of collagen or other proteins for calcium.
            Normally, ATP is considered to be the most important substance governing such changes of protein
            conformation or binding properties, but ordinarily, ATP and CO2 are closely associated, because both are
            produced in respiration. Gilbert Ling has suggested that hormones such as progesterone also act as cardinal
            adsorbants, regulating the affinity of proteins for salts and other molecules.
        </p>
        <p>
            Cells have many proteins with variable affinity for calcium; for example in muscle, a system called the
            endoplasmic reticulum, releases and then sequesters calcium to control contraction and relaxation. (This
            calcium-binding system is backed up by--and is spatially in close association with--that of the
            mitochondrion.) Ion-exchange resins can be chemically modified to change their affinity for specific ions,
            and molecules capable of reacting strongly with proteins can change the affinities of the proteins for
            minerals. What evidence is there that carbon dioxide could influence calcium binding? The earliest
            deposition of crystals on implanted material is calcium carbonate. (J. Vuola, et al, 1996.) In newly formed
            bone, the phosphate content is low, and increases with maturity. While mature bone has an apatite-like ratio
            of calcium and phosphate, newly calcified bone is very deficient in phosphate (according to Dallemagne, the
            initial calcium to phosphorus ratio is 1.29, and it increases to 2.20.) (G. Bourne, 1972; Dallemagne.)
        </p>
        <p>
            The carbonate content of bone is often ignored, but in newly formed bone, it is probably the pioneer.
            Normally, "nucleation" of crystals is thought of as a physical event in a supersaturated solution, but the
            chemical interaction between carbon dioxide and amino groups (amino acids, protein, or ammonia, for example)
            removes the carbon dioxide from solution, and the carbamino acid formed becomes a bound anion with which
            calcium can form a salt. With normal physiological buffering, the divalent calcium (Ca2+) should form a link
            between the monovalent carbamino acid and another anion. Linking with carbonate (CO32-), one valence would
            be free to continue the salt-chain. This sort of chemistry is compatible with the known conditions of bone
            formation.
        </p>
        <p>
            Klein, et al. (1996), think of uncoupled oxidative phosphorylation in terms of "subtle thermogenesis," which
            isn't demonstrated in their experiment, but their experiment actually suggests that stimulated production of
            carbon dioxide is the factor that stimulates calcification. Their experiment seems to be the in vitro
            equivalent of the various observations mentioned above. DHEA, which powerfully stimulates bone formation, is
            (like thyroid and progesterone) thermogenic, but in these cases, the relevant event is probably the
            stimulation of respiration, not the heat production. In pigs (Landrace strain) susceptible to malignant
            hyperthermia, there is slow removal of calcium from the contractile apparatus of their muscles. Recent
            evidence shows that an extramitochondrial NADH-oxidase is functioning. This indicates that carbon dioxide
            production is limited. I think this is responsible for the cells' sluggishness in expelling calcium.
        </p>

        <p>
            Stress-susceptible pigs show abnormalities of muscle metabolism (e.g., high lactate formation) that are
            consistent with hypothyroidism. (T. E. Nelson, et al., "Porcine malignant hyperthermia: Observations on the
            occurrence of pale, soft, exudative musculature among susceptible pigs," Am. J. Vet. Res. 35, 347-350, 1974;
            M. D. Judge, et al., "Adrenal and thyroid function in stress-susceptible pigs (Sus domesticus)," Am. J.
            Physiol. 214(1), 146-151, 1968.)
        </p>
        <p>
            Malignant hyperthermia during surgery is usually blamed on genetic susceptibility and sensitivity to
            anesthetics. (R. D. Wilson, et al., "Malignant hyperpyrexia with anesthesia," JAMA 202, 183-186, 1967; B.A
            Britt and W. Kalow, "Malignant hyperthermia: aetiology unknown," Canad. Anaesth. Soc. J. 17, 316-330, 1970.)
            Hypertonicity of muscles, various degrees of myopathy and rigidity, and uncoupling of oxidative
            phosphorylation occur in these people, as in pigs. Lactic acidosis suggests that mitochondrial respiration
            is defective in the people, as in the pigs. Besides the sensitivity to anesthetics, the muscles of these
            people are abnormally sensitive to caffeine and elevated extracellular potassium. During surgery, artificial
            ventilation, combined with stress, toxic anesthetics, and any extramitochondrial oxidation that might be
            occurring (such as NADH-oxidase, which produces no CO2), make relative hyperventilation a plausible
            explanation for the development of hyperthermia. Hyperventilation can cause muscle contraction. Panting
            causes a tendency for fingers and toes to cramp. Free intracellular calcium is the trigger for muscle
            contraction (and magnesium is an important factor in relaxation.) Capillary tone, similarly, is increased by
            hyperventilation, and relaxed by carbon dioxide. The muscle-relaxing effect of carbon dioxide shows that the
            binding of intracellular calcium is promoted by carbon dioxide, as well as by ATP. The binding of calcium in
            a way that makes it unable to interfere with cellular metabolism is, in a sense, a variant of simple
            extrusion of calcium, and the binding of calcium to extracellular materials. A relaxed muscle and a strong
            bone are characterized by bound calcium.
        </p>
        <p>
            Activation of the sympathetic nervous system promotes hyperventilation. This means that hypothyroidism, with
            high adrenalin (resulting from a tendency toward hypoglycemia because of inefficient use of glucose and
            oxygen), predisposes to hyperventilation.
        </p>
        <p>
            Muscle stiffness, muscle soreness and weakness, and osteoporosis all seem to be consequences of inadequate
            respiration, allowing lactic acid to be produced instead of carbon dioxide. Insomnia, hyperactivity,
            anxiety, and many chronic brain conditions also show evidence of defective respiration, for example, either
            slow consumption of glucose or the formation of lactic acid, both of which are common consequences of low
            thyroid function. Several studies (e.g., Jacono and Robertson, 1987) suggest that abnormal calcium
            regulation is involved in epilepsy. The combination of supplements of thyroid (emphasizing T3), magnesium,
            progesterone and pregnenolone can usually restore normal respiration, and it seems clear that this should
            normalize calcium metabolism, decreasing the calcification of soft tissues, increasing the calcification of
            bones, and improving the efficiency of muscles and nerves. (Magnesium, like carbonate, is a component of
            newly formed bone.) The avoidance of polyunsaturated vegetable oils is important for protecting respiration;
            some of the prostaglandins they produce have been implicated in osteoporosis, but more generally, they
            antagonize thyroid function and they can interfere with calcium control. The presence of the "Mead acid"
            (the omega-9 unsaturated fat our enzymes synthesize) in cartilage suggests a new line of investigation
            regarding the bone-toxicity of the polyunsaturated dietary oils.

            <strong>Pathological Science &amp; General Electric:Threatening the paradigm</strong>
        </p>
        <p>
            Everything in biology depends on the internal order of cells, and on the interactions of each cell with its
            surroundings. All of these orderly interactions involve contacts between biological molecules and water. The
            forces regulating interactions on that scale must be understood before life can be understood, but the
            nature of the forces at these interfaces has been controversial for 100 years. In 1953, physicist Irving
            Langmuir gave a talk at the General Electric laboratory about what he called "pathological science." That
            talk is still resonating in the scientific culture, and it is used to reinforce attitudes similar to those
            held by Langmuir, i.e., the dominant scientific paradigm of the 20th century, and to justify certain
            institutions that regulate innovation. For Langmuir, there was a clearly defined "scientific method," and he
            said some people were led away from the proper method by wishful thinking to interpret ambiguous results as
            confirmations of their hypothesis. He listed 6 symptoms of pathological science: 1) An effect produced by a
            barely detectable cause, and 2) the effect is barely detectable, or many measurements are needed because of
            the very low statistical significance of the results, 3) claims of great accuracy, 4) they involve fantastic
            theories contrary to experience, 5) criticisms are met by <em>ad hoc</em> excuses, and 6) the ratio of
            supporters to critics approaches 50%, then fades toward zero. He failed to mention these features in any
            research that supported his view of things, and called an idea pathological when people continued to work on
            it despite disapproval by the recognized experts. He didn't mention the Nobel prizes that were given for the
            worm theory of cancer or for treating psychological problems with lobotomies, and he didn't mention that
            there were organized campaigns against the publication of disapproved ideas.The dominant view in biology,
            which is analogous to Langmuir's view in physics, is that all decisive cellular processes involve the direct
            mechanical contact of one molecule with another, the activation of a lock (an enzyme or receptor) by a key
            that has the right shape, or the adhesion of a molecule to another substance according to its chemical
            composition. An alternative view, now clearly supported by the evidence, is that there are forces that
            aren't merely between molecular surfaces, but rather that the local conditions at the surfaces of proteins
            and other molecules, and the properties of the solvent water, are modified by the surrounding conditions. It
            is this alternative view that is now making progress in understanding disease and health, regeneration and
            degeneration. But to judge the new work, it's important to know the nature of the opposition.Thomas Edison,
            who was adept at publicizing himself as the inventor of ideas he had bought or stolen, founded General
            Electric. Attempting to eliminate Nikola Tesla's system of alternating current, since Edison was invested in
            direct current systems, Edison's GE tried to convince the public that direct current was safer, by using
            alternating current to electrocute an elephant, and by promoting its use in the electric chair. GE
            eventually gave up the direct current technology for electrifying cities, and they refined the electric
            light bulb and were fairly successful in controlling, practically monopolizing, that market, and in
            shortening the life of incandescent bulbs. Carbon filament bulbs made around 1900 often lasted decades; I
            had one that kept working until it was broken during a move in 1960. Light bulbs made in England 65 years
            ago, and in the Soviet Union, and bulbs currently made in China, had a life expectancy five times as long as
            the bulbs made in the US since GE learned how to carefully control the rate at which the tungsten filament
            deteriorates. Irving Langmuir was their leading light bulb scientist. In his 1932 Nobel lecture, he
            tediously argued that molecules of gas can form only one layer on a surface such as a filament. About 17
            years earlier, Michael Polanyi had demonstrated that molecules can be adsorbed in multilayers, but his
            evidence was dismissed because, according to the understanding of industrial experts such as Langmuir, and
            the leading scientific authorities, Einstein, Nernst, and Haber, it was impossible. They were committed to
            an explanatory system that didn't allow events such as those Polanyi described.Although Polanyi knew that
            his adsorption isotherm was more realistic than Langmuir's (he had demonstrated many cases that Langmuir's
            didn't describe correctly), and also easier to understand, he taught Langmuir's isotherm to his students,
            because he knew that they would be required to know it to pass their examinations. He knew he had risked his
            career by his earlier exposition of his ideas, and he was unwilling to endanger his students' careers by
            involving them in the controversy.From 1920 to 1926, before the advent in 1927 of "quantum physics" (with
            its still-argued features of delocalized electrons, molecular orbitals, resonance, non-locality,
            incommensurability, indeterminism), Polanyi had turned his attention from the physics of adsorption to
            chemical structure, and his group was the first to show that cellulose was made up of long molecules,
            polymers, rather than of just associated clusters. That idea didn't catch on, so he turned to the behavior
            of crystals and metals. He found that crystals were much weaker than they should be, according to the
            strength of the bonds between their atoms, and showed that this was because of defects, and that during
            repeated stresses, they became weaker, as energy migrated through relatively long distances in the
            substance, to concentrate the defects. The idea of lattice defects was acceptable at that time, but
            long-range mobility of bond energy was no more acceptable then than it had been when J.C. Bose described
            metal fatigue, decades earlier. Polanyi also showed that the strength and rigidity of a crystal were altered
            when the crystal was immersed in water. Again, such an influence of a surface on the over-all physical
            properties of a solid substance had no noticeable effect on the scientific culture, although his results
            were published in the major journals. To adjust one's interpretive system at that time to rationalize
            Polanyi's results would have required discarding the basic assumptions that were behind Einstein's
            explanation of the photoelectric effect, and maybe even his theory of Brownian motion. However, by 2011,
            fewer people have invested their personal development in those ideas of short-range electrical binding
            forces that prevailed early in the 20th century, and now, for example, the evidence of "delocalized holes in
            DNA" can be discussed more openly. Eventually, science textbooks may be rewritten to show a steady
            progression of understanding from Bose, though Polanyi, Perutz, Szent-Gyorgyi, Ling, and Damadian (inventor
            of the MRI, holder of the patents infringed by GE, non-winner of the Nobel prize). In 1933 J.D. Bernal had
            proposed a structural model of water that contained a considerable amount of order (Bernal and Fowler, 1933)
            but by the 1950s the idea of spontaneous ordering in water was out of style, and he worked out a more random
            structure. Max Perutz, continuing the study of hemoglobin he had begun with Bernal, became concerned with
            long range forces acting through water: "The nature of the forces which keep particles parallel and
            equidistant across such great thicknesses of water is not yet clear." Normal wet crystals of methemoglobin
            contain regular layers of water 15 Angstroms thick. He suggested that a laminated structure of the water
            could plausibly explain his measurements. Comparing the protein crystal to montmorillonite particles, which
            incorporate several layers of water, each 3 Angstroms thick, each layer of water in the protein crystal
            would be 4 Angstroms thick, since swelling proceeds in discrete steps of that thickness. 52.4% of the volume
            of Perutz's normal, stable, wet protein crystals consisted of liquid. Part of the water is a fixed
            monolayer, but the rest is apparently in the form of mobile, interactive, multilayers. By 1952, Perutz had
            decided that long range forces weren't involved in hemoglobin crystallization, but he didn't comment on the
            long range ordering of clays, tobacco mosaic viruses, and other particles and gels. In 2005, an interlaminar
            distance of 17.9 Angstroms, or six layers of water, still seems to be stable in hydrated montmorillonite
            (Odriozola &amp; Aguilar, 2005). Clay continues to be studied in relation to nuclear waste disposal, so the
            effects of surfaces on water's properties haven't been entirely excluded from science. The interfacial water
            in clay has special catalytic properties that make it interesting to many researchers (Anderson,
            1970)Bernal's and Perutz' conformity in the 1950s rejection of long range forces and an ordered structure of
            water represented the dominant ideas in physics and physical chemistry, but many people (with very little
            financial or institutional support) were continuing to study the structure of water, both in the bulk phase
            and near surfaces, as in cells. Philippa Wiggins, Albert Szent-Gyorgyi, Carlton Hazlewood, Freeman Cope, and
            Ray Damadian were among the most active proponents of the importance of structured water in living cells.
            Walter Drost-Hansen showed that water near surfaces (vicinal water) is several percent less dense, and has a
            greater heat capacity, than bulk water, and that bulk water undergoes transitions at certain temperatures
            that alter its effects on enzyme reactions.The question regarding the nature of the forces at surfaces or
            interfaces affects how we think about everything, from life to nuclear energy. The political and economic
            implications of "non-local energy" (which is most obvious at surfaces) have at times led to organized
            campaigns to discourage research in those areas. When Alexandre Rothen found (beginning in 1946) that
            enzymes and antibodies had non-local effects, several prestigious publications claimed to show how he must
            have been mistaken<strong>: </strong>The<strong> </strong>films<strong> </strong>he used must have been
            porous, despite his demonstrations of their continuity. The methods he developed at Rockefeller Institute
            quickly became standard for accurately measuring very thin films. In the early 1970s, a GE employee, Ivar
            Giaever, visited Rothen's lab to learn his methods. Shortly after his visit, he demonstrated his "new
            method" to the press. I saw an article about it in Science News, and wrote them a short letter, pointing out
            that the method had been developed and used by Rothen much earlier<strong>;</strong> they printed my note,
            which could be seen as a criticism of the author of the news article. About a week later, I got a letter
            from Rothen, thanking me for writing to the magazine; he said they had refused to publish his own letter
            explaining the situation, including his interactions with Giaever during the visit. I assume that the
            magazine felt some kind of pressure to protect Giaever and GE from an authoritative accusation of scientific
            dishonesty.In 1968 when I began studying biology at the University of Oregon, the professor of microscopy,
            Andrew Bajer, posted a display of dozens of micrographs, with explanatory captions, along the halls near the
            entrance of one of the science buildings. The one that interested me most showed orderly rows of regularly
            formed objects on a smooth surface. The caption described it as clusters of sodium atoms, deposited from
            vapor, on a film of a polymer (formvar, I think), under which was a quartz crystal. The caption noted that
            the sodium atoms had condensed in a pattern representing the crystal structure of the underlying quartz.
            Although Rothen's work involved proteins deposited from solution, rather than sodium atoms deposited from
            vapor, Bajer's image illustrated visually the projection of the forces of crystal structure through an
            amorphous film. This seemed to be a graphic representation of Polanyi's adsorption potential, a force acting
            on atoms in the space near a surface, as opposed to Langmuir's local atomic force that didn't reach beyond
            the first layer of atoms. The long range order in this case arranged atoms geometrically, while Rothen's
            preparations showed a "projected" specificity, but of a more complex sort. Just a few months later, someone
            who knew of Stephen Carter's demonstration that fibroblasts will migrate on a glass slide coated with a gold
            film, toward areas of greater thickness of the metal, did a similar experiment, but with a formvar film
            between the gold and the cells. The cells still migrated up the gradient, toward the area of thicker gold
            under the film. The reaction to that publication was the same as the reaction to Rothen's work 20 years
            before, the formvar films contained holes, and the cells were reaching through the film to touch the metal
            surface, sort of like kids peeking around a blindfold when they aren't supposed to be watching. I didn't
            understand how the holes would explain anything, even if there were holes and if the cells had put out many
            long filopodia to reach through the film, but in fact making a formvar film is a very standardized
            technique. They can be made "holey," or like a very open net, or they can be made solid, just by choosing
            the concentration of the polymer used. The difference is very clear, under an electron microscope, but the
            professors needed an excuse for dismissing something they didn't want to understand. Further work was
            discouraged by their ridicule.In Russia, GE had very little influence on the acceptability of ideas in
            science, and Boris Deryagin continued (from the 1930s until 1990) to study the properties of water near
            surfaces. In 1987 his group demonstrated that cells can clear particles from a space around themselves,
            extending more than a cell's diameter away. This distance is similar to the cell free zone in flowing blood
            adjacent to the walls of arterioles, which is probably the result of multiple interacting forces. At
            present, processes such as cell adhesion of leukocytes and stem cells (and tumor cells) to the blood vessel
            wall and movement through the blood vessel into the tissues (diapedesis) is explained in terms of adhesion
            molecules, disregarding the plausible effects of long range attractive or repulsive forces. Clumping or
            sludging of red blood cells occurs when the organism is failing to adapt to stress, and could be reasonably
            explained by a failure of protective repulsive fields. These fields are developed and maintained by
            metabolism, primarily oxidative energy metabolism, and are modified by endogenous regulatory substances and
            external conditions, including electromagnetic and electrical fields. 100 years ago, Albert Einstein was a
            major influence in popularizing the "only local" dogma of atomic interactions. (His work led directly to
            "quantum physics," but he never accepted its irrational implications.<strong><sup>(1)</sup></strong> I don't
            think he ever considered that the assumptions in his [atomic-quantized] theory of the photoelectric effect
            were the problem.) One charged atom is completely neutralized by its association with an oppositely charged
            atom, and the force is described by the inverse square law, that the force decreases with the square of the
            distance between point charges, meaning that the force is very strong at very small distances. However, a
            physical<strong><em>surface</em></strong>, a plane where one substance ends and another begins, follows
            different rules. Different substances have different electron affinities, creating a phase boundary
            potential, a charged layer at the interface. (Electrical double layers at interfaces are important in
            semiconductors and electrodes, but biologists have carefully avoided discussing them, except in the very
            narrow context of electrodes.) The electrically active surface of a substance, even though it's made of
            atoms and electrons, projects its electrical field in proportion to its area. This principle is as old as
            Coulomb's law, but the habit of thinking of electrical charge on the atomic scale seems to make people
            forget it. It's exactly the sort of space-filling field that Polanyi's adsorption isotherm describes. It's
            also involved in crystal strength and elasticity as studied by Polanyi, in piezoelectricity, and in
            generation of semiconduction in amorphous materials, as used in Stan Ovshinsky's processes.Long range
            structural and electronic interactions produce "antenna" effects, which are sensitive to very weak fields,
            whether they originate inside or outside of the organism. Magnetobiology is often treated as a
            pseudo-science or pathological science, because "real science" considers heating and chemical bond reactions
            to be the only possible effects of low energy fields or radiation. Solco Tromp, beginning in the 1930s,
            showed that cells behave like liquid crystals, and that liquid crystals can respond to very low electrical
            and magnetic fields.If the adsorption potential structures the water in its region of space, this
            interfacial water is now a new <em>phase</em>, with different physical properties, including new catalytic
            properties, such as those recognized by the clay investigators (which increased its ability to dissolve the
            clay minerals).Several versions of Langmuir's Pathological Science talk have been published, some of them
            adding new examples, including "polywater." Langmuir died in 1957, and the first example of polywater was
            observed by N.N. Fedyakin was observed in 1961. When finely drawn quartz or Pyrex glass capillary tubes
            (with inside diameter of up to a tenth of a millimeter) are suspended in a container with the air pressure
            reduced, above a container of distilled water, so that they are exposed to pure water vapor at room
            temperature, after a period of an hour or more (sometimes days or weeks were required) a small drop of
            liquid condenses inside some (a small percentage) of the capillary tubes. Above some of the original drops,
            a second drop sometimes appeared, that would enlarge as the first drop shrank. This separation of water into
            two fractions was itself anomalous, and the upper drop was found to be denser than normal water. Many people
            began studying its properties. Fedyakin found that its thermal expansion was greater, and its vapor pressure
            lower, than ordinary water. Others found that it had a higher refractive index, viscosity, and surface
            tension, as well as greater density, than ordinary water. Birefringence (the splitting of a beam of light
            into two rays when it passes through an ordered material) was observed in the anomalous water, and this
            usually indicates the presence of a polymer (Fedyakin, et al., 1965; Willis et al., 1969; Lippincott, et
            al., 1969) or crystallinity. The water associated with clay is also birefringent (Derjaguin and
            Greene-Kelly, 1964), and its properties are different when the clay absorbs it from the vapor phase or from
            liquid water.Hysteresis is a lag in the behavior of a system, resulting when the internal state of the
            system is altered by an action, so that it responds differently to a repetition of that action; it's the
            memory of a system that exists only when the system has internal structure. For example, a gas has
            relatively little hysteresis. Perfect elasticity is one extreme of an ordered solid, but most solids have
            some hysteresis, in which the deformed material fails to spring back immediately. Hysteresis of adsorption
            can be seen at the edges of a drop of water on a tilted surface, with a steeper contact angle on the newer
            contact at the lower edge, showing a reluctance of the water to wet a new surface, a lower contact angle
            where the drop is pulling away from the upper surface, a reluctance to break the contact. The same is seen
            at the edges of an evaporating-shrinking drop, or a growing drop. Everyone perceives this memory function of
            water.Boris Deryagin studied both the elasticity and the hysteresis of water near surfaces, and both
            approaches showed that it contained internal structure. Many dogmatic professors denied that water could
            show elasticity or "memory," because of their interpretive system/mental rigidity. When Fedyakin got the
            help of Deryagin's lab in analyzing the anomalous material, many different methods of purifying the glass
            and the water and the vessel were tried, and its properties were analyzed in many different ways. When
            Deryagin first described the material at a conference in Europe, there was great interest, and eventually
            hundreds of people began investigating it. A British laboratory was the first to get a sample of Deryagin's
            material in 1966, and their tests confirmed Deryagin's. The US Bureau of Standards, having the best
            analytical instruments in the world (including a microscope spectrometer), studied it carefully. They
            (Lippincott, Stromberg, Grant, &amp; Cessac, 1969) found that its bonds were stronger than those in ordinary
            water, and they compared its absorption spectrum (by computer) with those of 100,000 known substances, and
            found that it corresponded with nothing previously known. It didn't have the absorption band of normal
            water. When it evaporated, it left no visible residue, and it turned into ordinary water when heated. They
            concluded that the physical structure that would best fit its absorption spectrum was a polymerized form of
            water, so they called it "polywater." Later, Lippincott and others (Page, et al., 1970; Petsko, 1970) did
            proton magnetic resonance analyses that showed a difference of polywater from normal water in the hydrogen
            bonding, a "deshielding" of the protons, meaning that the electrons were arranged differently in the
            molecules.In 1969 there were many threats to the dominant paradigm, and many people were demanding a change
            in the government's funding priorities. The public excitement about polywater following the many
            confirmations of its existence was disturbing to the defenders of the paradigm. Philip Abelson, the chief
            editor of Science magazine, used the magazine to further his political beliefs. Denis Rousseau, a young
            researcher at Bell Labs (who now writes about pathological science), published a series of articles in
            Science describing his tests of polywater. He played tennis until his tee-shirt was soaked with sweat, then
            extracted and concentrated the sweat into a small gummy pellet. He reported that the infrared spectrum of
            the sweat concentrate (largely sodium lactate) was very similar to that of polywater. One of the techniques
            he used to identify impurities (electron spectroscopy) requires a high vacuum, so there couldn't be any
            normal water present. The water associated with ionic impurities is driven off at low temperatures compared
            to the temperature needed to decompose the anomalous water.Although Rousseau's "explanation" was ludicrous,
            it was just the thing the professors needed to prevent further challenges to their paradigm. Although
            Deryagin published more evidence of the purity of the anomalous water in 1972, by 1973 the mass media,
            including Science magazine, were saying that polywater didn't exist, and that Deryagin had admitted that he
            was mistaken. But polywater was Lippincott's term, and what Deryagin said was that silica was the only
            impurity that could be identified in the anomalous material. There are many antecedents to anomalous water
            in the literature. In the 1920s, W.A. Patrick of Johns Hopkins and J. L. Shereshefsky at Howard university
            investigated the properties of water in fine capillary tubes and found that the vapor pressure wasn't the
            same as that of normal water. (This is what would have been expected, if Polanyi's adsorption isotherm had
            been accepted.) The density of water in clay has been found to be slightly less than normal. This water
            bound to clay requires a high temperature to eliminate, similar to the decomposition temperature of
            polywater. The catalytic properties of interfacial water in clay are recognized, causing it to solublize
            components of the clay. So it's hard to imagine that there wouldn't be some silica in the material formed in
            quartz or glass capillary tubes.<strong>The only thing pathological about the polywater episode was the
                extreme effort that was made to stigmatize a whole category of research, to restore faith in the old
                doctrine that insisted there are no long range ordering processes anywhere in the universe.</strong> The
            successful campaign against polywater strengthened the mainstream denial of the evidence of ordering in
            interfacial and intracellular water, kept the doctrine of the lipid bilayer cell membrane alive, and up
            until the present has prevented the proper use of MRI scans in medical diagnosis.In 1946, while the
            government was studying the way nuclear fallout was influenced by the weather, a group at GE, led by
            Langmuir, began experimenting with weather control by means of "cloud seeding." Langmuir observed that the
            energy in a cloud system was greater than that in an atomic bomb, and that by seeding clouds in Europe,
            disastrous weather effects could be created in the Soviet Union. The GE group convinced the Pentagon to
            become involved in weather control. (The physicist Ross Gunn was transferred directly from work on the
            atomic bomb to direct the cloud seeding project.) In one of Langmuir's seeding experiments, he claimed that
            he had changed the direction of a hurricane moving toward the U.S. When a young researcher pointed out that
            the weather service had predicted exactly that change of direction, based on the temperatures of ocean
            currents, Langmuir became angry, and told the man that he wasn't going to explain it to him, because he was
            too stupid to understand. Langmuir's attitude toward science was exactly what GE wanted; his career and
            reputation were part of the corporation's public relations and business plan. Science was whatever GE
            thought was good for their business. That science was pathological, sometimes by Langmuir's own defining
            features, most of the time by the effects it has had on society. The Manhattan Project was central to GE's
            business plan, and when the bomb project was completed GE and the Atomic Energy Commission found that the
            same subsidies could be used to develop nuclear generators of electricity. Following Edison's pioneering
            work with x-rays, x-ray imaging machines had become very profitable for GE. It was important to assure the
            public that medical, industrial, and military radiation was well understood, well controlled, safe, and
            essential for the general welfare. In their view, if every woman could have access to GE's x-ray mammograms,
            for example, almost all breast cancers could be cured. The radiation exposure from living near a GE nuclear
            power generator is infinitesimal compared to living in Denver or flying in an airplane. (There is some
            discussion of these issues in my January, 2011 newsletter, "Radiation and growth.") Public relations
            involves everything from "basic research" to television advertising.If nuclear energy is as safe as the
            industry and governments say it is, the reactors should be located in the centers of large cities, because
            transmitting electric power long distances is presently wasting 50% of the power (Hirose Takashi, The
            Nuclear Disaster that could destroy Japan...and the world, 2011). Admiral Rickover, influential advocate of
            nuclear power, said "...every time you produce radiation, [a] horrible force [is unleashed,] and I think
            there the human race is going to wreck itself. [We must] outlaw nuclear reactors" (January, 1982
            congressional testimony) Helen Caldicott says Fukushima is many times worse than Chernobyl. The radioactive
            cesium in German mushrooms and truffles hasn't decreased 25 years after Chernobyl, and the German government
            is spending increasing amounts to compensate hunters for the wild boars (who eat truffles) that must be
            disposed of as radioactive waste.<strong><sup>(2)</sup></strong>General Electric sent its condolences to the
            people of Japan, and said the reactors of that design had functioned well for 40 years; they didn't mention
            that Unit I at Fukushima had been scheduled to be shut down on March 26, 2011, the end of its 40 year life
            expectancy. In late March, as the accident continued, Tepco applied for a permit to build two new reactors
            at the Fukushima site. In the US, the government continues its loan guarantee policy to subsidize new
            reactor construction. After many years of working with his metalized slides, Alexandre Rothen found that
            their activity, the strength of their long-range influence, varied with a 24 hour cycle, and that their
            activity could also be destroyed or restored by putting them in a magnetic field, parallel or perpendicular
            to the surface. Around the same time, a Russian biochemist, Simon Shnoll, noticed that there were cyclic
            changes in well defined enzymic reactions. Like Rothen, Shnoll did experiments that showed that the earth's
            motion (relative to the stars) affected measurements in the laboratory, even measurements of alpha particles
            produced by nuclear fission. Organized matter, whether it's cellular or in the crystalline solid state, is
            susceptible to surrounding conditions.In 1971 or '72 I learned of H.C. Dudley's idea of a "neutrino sea,"
            that he suggested might be equivalent to the "luminiferous ether" that had previously been used to explain
            light and electromagnetism. I wrote to him, asking if he thought neutrinos could be involved in biological
            ordering processes by resonating with matter under some circumstances. He had been developing a theory, in
            which atomic nuclei might interact with a neutrino "ether," in ways that could affect the decay rate of the
            unstable isotopes, and so it didn't seem unreasonable to him that biological structures might also interact
            with neutrinos. In October, 1972, he published a purely theoretical article in which he explained that
            nuclear reactors might under some conditions become dangerously unstable. I had earlier seen a newspaper
            article about an experiment by a physicist, J.L. Anderson, in which radioactive carbon-14 didn't follow the
            normal rules of random decay, when the isotope was incorporated into an oil, which was spread in a monolayer
            on a metal surface. By chance, Anderson's experimental article was published simultaneously with Dudley's
            theoretical article, though neither one knew of the other's work. Nearly all physicists said his results
            weren't possible, because the small forces involved in adsorbing an oil to a metal surface were
            infinitesimal compared to the force needed to cause nuclear reactions. Over the next few years, Dudley and
            others did some experiments that appeared to confirm Anderson's results, showing that the rate of nuclear
            reactions can be modified by mild changes in the physical state of the unstable elements.Anderson's and
            Dudley's work didn't get much attention from the public, so there was no need for the defenders of the
            dominant paradigm to attack it. There was no financial support for continuing their research.Behind the
            industries' assurances that "low level" radiation is safe, whether it's ionizing radiation, microwave or
            broadcast frequency electromagnetic radiation, is their reductionist approach to physics, chemistry, and
            biology. Those doctrines no longer have the prestige that they once did, but their pathological,
            authoritarian "science" culture is being sustained by the influence of corporations on mass culture.With the
            institutions of research and education controlled by pharmaceutical, military and industrial interests for
            their own benefit, fundamental progress in knowledge is a threat to the system. NOTES1. From Einstein's 1926
            letter to Max Born: "Quantum mechanics is very worthy of regard. But an inner voice tells me that this is
            not yet the right track. The theory yields much, but it hardly brings us closer to the Old One's secrets. I,
            in any case, am convinced the He does not play dice." Quoted in P. Busch and G. Jaeger, "Unsharp quantum
            reality," 4 May 2010.2. None of the major institutions in the US are providing basic information about
            protection from Fukushima's radioactive fallout. Eating foods produced before the arrival of the radioactive
            rain, feeding old foods to chickens and milk animals, and keeping your metabolic rate high, are the main
            defenses. Eventually, fertilizing crops with mined minerals, and enriching the atmosphere with carbon from
            coal will dilute the radioactive isotopes from the nuclear accidents.<h3>REFERENCES</h3>DM Anderson, <strong

                                phosphate-regulating gene named klotho (after one of the Fates in Greek mythology) has
                                caused a lot of rethinking of the biological role of phosphate. In the 19th century,
                                phosphorus was commonly called brain food, and since about 1970, its involvement in cell
                                regulation has become a focus of reductionist thinking. ATP, adenosine triphosphate, is
                                seen as the energy source that drives cell movement as well as the "pumps" that maintain
                                the living state, and as the source of the cyclic AMP that is a general activator of
                                cells, and as the donor of the phosphate group that activates a great number of proteins
                                in the "phosphorylation cascade." When tissues calcified in the process of aging,
                                calcium was blamed (ignoring the existence of calcium phosphate crystals in the
                                tissues), and low calcium diets were recommended. Recently, when calcium supplements
                                haven't produced the intended effects, calcium was blamed, disregarding the other
                                materials present in the supplements, such as citrate, phosphate, orotate, aspartate,
                                and lactate.</span></span></span></span></span>

                        popular view, a stimulus causes a change of shape in a receptor protein, causing it to become an
                        active enzyme, catalyzing the transfer of a phosphate group from ATP to another protein, causing
                        it to change shape and become activated, and to transfer phosphate groups to other molecules, or
                        to remove phosphates from active enzymes, in chain reactions. This is standard biochemistry,

                        followed the activation. Phosphorylation was involved in activation of the enzyme, but if
                        something else first activated the enzyme (by changing its shape), the addition of the phosphate

                                contraction of a muscle or nerve, heat is given off, causing the temperature to rise.
                                During relaxation, recovering from excitation, heat is absorbed (Curtin and Woledge,
                                1974; Westphal, et al., 1999; Constable, et al. 1997). In the case of a nerve, following

                                described the phenomenon of "fatigue contracture," in which the muscle, when it reaches
                                the point at which it stops responding to stimulation, is maximally contracted (this has
                                also been called delayed relaxation). Ischemic contracture, in the absence of blood
                                circulation, occurs when the muscle's glycogen is depleted, so that ATP can no longer be
                                produced anaerobically (Kingsley, et al., 1991). The delayed relaxation of hypothyroid
                                muscle is another situation in which it is clear that ATP is required for relaxation.
                                (In the Achilles tendon reflex test, the relaxation rate is visibly slowed in
                                hypothyroidism.) A delayed T wave in the electrocardiogram, and the diastolic
                                contracture of the failing heart show the same process of delayed relaxation.
                                Supplementing the active thyroid hormone, T3, can quickly restore the normal rate of
                                relaxation, and its beneficial effects have been demonstrated in heart failure

                                be lost from bones cause calcium to increase in the soft tissues, such as blood vessels.
                                The role of phosphate in forming calcium phosphate crystals had until recently been
                                assumed to be passive, but some specific "mechanistic" effects have been identified. For
                                example, increased phosphate increases the inflammatory cytokine, osteopontin
                                (Fatherazi, et al., 2009), which in bone is known to activate the process of
                                decalcification, and in arteries is involved in calcification processes (Tousoulis, et
                                al., 2012). In the kidneys, phosphate promotes calcification (Bois and Selye, 1956), and
                                osteopontin, by its activation of inflammatory T-cells, is involved in the development
                                of glomerulonephritis, as well as in inflammatory skin reactions (Yu, et al., 1998).
                                High dietary phosphate increases serum osteopontin, as well as serum phosphate and
                                parathyroid hormone, and increases the formation of tumors in skin (Camalier, et al.,
                                2010).&nbsp; Besides the activation of cells and cell systems, phosphate (like other
                                ions with a high ratio of charge to size, including citrate) can activate viruses
                                (Yamanaka, et al., 1995; Gouvea, et al., 2006). Aromatase, the enzyme that synthesizes
                                estrogen, is an enzyme that's sensitive to the concentration of phosphate (Bellino and
                                Holben, 1989).</span></span></span></span></span>

                        gallon of milk (some of it in the form of cottage cheese), and the juice of half an orange,
                        besides some vitamins and minerals. The experimenters remarked about the surprising
                        disappearance of the normal fatigue after a day's work, as well as the normalization of his high
                        blood pressure and high cholesterol, and the permanent disappearance of his frequent life-long
                        migraine headaches. His respiratory quotient increased (producing more carbon dioxide), as well
                        as his rate of resting metabolism. I think the most interesting part of the experiment was that
                        his blood phosphate decreased. In two measurements during the experimental diet, his fasting

                                and magnesium, with the calcium retention much larger than the magnesium, the minerals
                                were probably mostly being incorporated into their bones. Their phosphate balance,
                                however, was slightly negative on the "high fructose" diet. If the sugar was having the
                                same effect that it had on William Brown in 1938 (and in animal experiments), some of
                                the phosphate loss was accounted for by the reduced amount in blood and other body
                                fluids, but to continue through the months of the experiment, some of it must have
                                represented a change in the composition of the bones. When there is more carbon dioxide
                                in the body fluids, calcium carbonate can be deposited in the bones (Messier, et al.,
                                1979). Increased carbon dioxide could account for a prolonged negative phosphate
                                balance, by taking its place in the bones in combination with calcium and
                                magnesium.&nbsp;</span></span></span></span></span>

                                1995), and by increasing the excretion of phosphate. Increased carbon dioxide (as
                                dissolved gas) and bicarbonate (as sodium bicarbonate) both increase the excretion of
                                phosphate in the urine, even in the absence of the parathyroid hormone. Below the normal
                                level of serum bicarbonate, reabsorption of phosphate by the kidneys is greatly
                                increased (Jehle, et al., 1999). Acetazolamide increases the body's retention of carbon
                                dioxide, and increases the amount of phosphate excreted in the urine.&nbsp;</span></span

        Hospital accidents kill more people than highway accidents. But when people die while they are receiving
        standard, but irrational and antiscientific treatments and “support,” the deaths aren’t counted as accidents.
        The numbers are large. Medical training and medical textbooks bear great responsibility for those unnecessary
        deaths. Most medical research is done under the influence of mistaken assumptions, and so fails to correct the
        myths of medical training. If the “consumers” or victims of medicine are willing to demand concrete
        justifications before accepting “standard procedures,” they will create an atmosphere in which medical mythology
        will be a little harder to sustain.
        <hr />

        A sentence taken out of context is likely to be misleading. A chemical equation that is concerned only with the
        reactants, catalyst, and product, can be misleading, and its industrial application is likely to produce
        devastation and pollution along with the intended product. In nature and industry, the reactants, products, and
        energy changes are linked to the ecology and to the economy. In physiological chemistry, events in the organism
        are linked to the environment so closely that food, water, air, soil, and pollution form a firmly linked
        functional system. But “medical physiology” has evolved as a separate thing, in which formulas that describe
        specific situations are linked to each other by fragmentary schemes, terminology, and computer models. This
        jerrybuilt scheme is even more roughly set into a hypothetical environment of “the origin of life,” “evolution,”
        “inheritance,” “society,” and a few other perfunctory contextualizations that have no more relevance to the
        subject than do the literary epigraphs that are often used at the beginning of chapters in medical books, to
        signify that the author isn’t just a technical hack. This physiological mythology has made possible a practice
        of medicine in which “genes” and “a virus” are regularly invoked to explain things that can’t be remedied, and
        in which any fleshy body is described as “well nourished,” and in which malnutrition and poisoning by pollutants
        are systematically dismissed as explanations for sicknesses, while thousands of different drugs are administered
        according to instructions given by their salesmen. It is also deeply linked to attitudes that have turned the
        practice of medicine into the surest way for an individual to get rich and retire early. It creates a sense of
        confidence that the physician is doing the right thing, because there is a little physiological rationale for
        everything.&nbsp;<strong><em>When a practice is replaced by its opposite, there is also a rationale for
                that.&nbsp;</em></strong>In fact, medical textbooks are written to rationalize the highly arbitrary
        practices of the industry. If, for some reason, perpetual motion machines had been as successful economically as
        steam engines were, laws of thermodynamics would have been written to describe them, just as thermodynamic laws
        were invented to describe the theory of steam engines. It was odd and interesting when a vice presidential
        candidate stepped to the podium several years ago and asked “who am I? What am I doing here?” But those
        questions are really of the greatest importance and interest, and physiology should be an attempt to understand
        more fully what we are, what we are doing, and how we are doing it. When we have comprehensive answers to those
        questions, then we will be in a position to create systematically valid solutions for our problems. For
        physiology, the equivalent of medicine’s “first do no harm” would be “first, don’t believe unfounded doctrines.”
        Accepting that principle puts a person into a critical attitude, and experiments can become actually
        “empirical,” an extension of experience that allows you to perceive new things, rather than “testing
        hypotheses.” Unless a hypothesis is a generalization from real experience, rather than a deduction from a
        doctrine, progress is likely to be very slow. A first step in developing a critical attitude is to identify the
        idols that stand in the way of real understanding.
        <strong>Immunity, intelligence, appetites, tumor growth, aging, the proper development of organs—everything that
            we think of as the biological foundations of health and sickness—will be misinterpreted if there are
            fundamental misconceptions about physiology.</strong>

        Physiology is the study of the vital functions of organisms, but especially when talking about “pathologic
        physiology,” great emphasis in physiology textbooks is given to the processes that maintain homeostasis of
        the&nbsp;<em>milieu interieur,</em>&nbsp;or the constancy of composition of the “fluid in which tissue cells are
        bathed.” Since cells are embedded in a gel-like matrix, “connective tissue,” the connective tissue should have
        some serious attention in physiology courses, but in practice its composition is described, and then the rest of
        physiology treats it as the “extracellular space.” Only specialists in the extracellular matrix are likely to
        take it seriously as a factor in physiology. If medical physiologists are likely to think of cells as being
        “bathed in fluid” which fills the empty spaces around the cells, they are also likely to think of the cell’s
        interior as a watery solution which “fills the space enclosed by the cell membrane.” It is this image of the
        organism that has made traditional biochemistry possible, since enzymes extracted from cells and dissolved in
        water had been thought to function the way they function in the living state. But the living cell isn’t like a
        tiny water-filled test-tube.
        <strong>Some of the points that should be considered in a realistic (and therefore coherent) physiology
            text:</strong>
        <strong>Connective tissues, ground substance</strong>— making a multicell organism--secreting the right amount,
        modifying/maintaining it, responding to the scaffolding--where the crucial&nbsp;<em>milieu interieur</em
        >&nbsp;is.
        <strong>Cellular energy, a structural idea</strong>—a finely organized catalyst, a readiness for work, and
        conditions that determine the equilibrium of reactions.
        <strong>The dimensions of the organism</strong>&nbsp;range from cellular fields to organismic intentions, via
        functional systems.
        <strong>Physiology should be understood in terms of its geochemical setting,</strong>&nbsp;because otherwise
        basic definitions will be built up in the belief that life is discontinuous from its physical environment,
        separated by membranes, and maintained by the expense of energy mainly to preserve gradients across those
        membranes<strong>;&nbsp;</strong>while in actuality the chemical energy released by living substance is spent in
        renewing structures, and the gradients are mainly passive physical-chemical consequences of structure. The
        spontaneous polymerization that occurs under volcanic conditions creates substances with intrinsic functions.
        The living state is a substance that is always being renewed as it interacts with its environment, and from the
        larger persepective, it is an evolving catalyst that modifies the environment so that the whole system
        approaches equilibrium with the energy that flows through it. Since the evolving system stores energy in its
        structure, the cosmic energy sources and sinks are at the boundaries of the system, and are the only questions
        that (so far) transcend the issue of life in its environment. The chemistry of the planet is tied up with cosmic
        energy, but the nature of the system as a whole is still relatively unexplored. If plants are bracketed by the
        sun, carbon dioxide and water, animals are bracketed by sugar and oxygen.
        <strong>Acid-base</strong>&nbsp;<strong>regulation</strong>--selectivity; physical chemistry of coral, bone;
        kidney, lung; roles of oxygen, carbon dioxide and protein.
        <strong>An Arrhenius base</strong>&nbsp;is something which produces hydroxide ions when it’s dissolved in water.
        <strong>Metal, an element that forms a base</strong>&nbsp;by combining with a hydroxyl group (or groups).
        <strong>Base,</strong>&nbsp;an electropositive element (cation) that combines with an anion to form a salt; a
        compound ionizing to yield hydroxyl ion.
        <strong>Electropositive</strong>&nbsp;<strong>atoms</strong>&nbsp;tend to lose electrons.
        <strong>Electronegative atoms</strong>, such as oxygen, chlorine, and fluorine, tend to take up an electron and
        to become negatively ionized.&nbsp;
        <strong>Definitions of Arrhenius and Lewis</strong>&nbsp;for acids and bases. It’s important to keep both sides
        of an ionizable compound in mind, and to pay more attention to electrons than to protons.
        <strong>A</strong>&nbsp;<strong>Lewis acid</strong>&nbsp;is an electron acceptor.
        <strong>Alkali reserve, (Stedman’s phrase:) “the basic ions, mainly the bicarbonates” (bicarbonates of this or
            that; there is no abstract “bicarbonate.”)</strong>
        <strong>Carbon dioxide is a neutral Lewis acid, that associates with the hydroxide ion.&nbsp;</strong>(This
        observation may be shocking to people who have thought too long in terms of abstract “bicarbonate.”)
        <strong>Carbon dioxide regulates water, minerals, energy and cellular stability, excitation, and

        Between 1947 and 1956, Arthur C. Guyton, of Ole Miss, wrote a textbook of medical physiology, and one of his
        students, J. E. Hall, has added chapters to it. It is the most widely used physiology textbook in the world. It
        may be more influential than the bible, since it has shaped the behavior of millions of doctors, affecting
        billions of people. Its success probably has something to do with Guyton’s unusual personal experience. After
        graduating from Harvard Medical School and, along with others from Harvard, working in germ warfare,* he
        contracted polio, and returned to Mississippi. As someone moving from the centers of excellence and power to the
        most backward state in the nation, instead of using textbooks he wrote handouts for the classes he taught there,
        devising what he thought were plausible explanations for everything in physiology. A personalized perspective
        and desire to keep things simple made the book, based on those handouts, readable and popular.&nbsp; The
        circulatory system, and the movement of fluids in the body, are at the center of physiology, so it is of
        interest that Guyton believed that, in the “spaces around cells,” there is a negative pressure, a partial
        vacuum, that sucks fluid out of the capillaries. He believed that this suction would balance a column of 5 or 10
        mm of mercury. The rib cage, and the force of the diaphragm muscle, can maintain a negative pressure around the
        lungs, preventing their elastic collapse, but there is no such shell around the rest of the body; if elastic
        fibers of connective tissue could be anchored to such a shell, then such a suction/vacuum would be
        conceivable.&nbsp; Hydrostatic and osmotic pressures interact in tissues, but even the hydrostatic forces
        produced by the heartbeat are known only approximately, as estimates, on the microscopic level. The belief in
        subatmospheric interstitial pressure is unreasonable on its face, and measurements are so inaccurate in the
        microcirculation that its disproof would be somewhat like proving that fairies aren’t responsible for the
        Brownian motions seen under a microscope. The oncotic/osmotic behavior of proteins in the blood and
        extracellular (the term&nbsp;<strong><em>interstitial</em></strong>&nbsp;implies the presence of empty spaces
        which aren’t really there) fluid is usually, in medical physiology, assumed to be a fixed quantity determined by
        the nature of the polymer. Swelling and syneresis (contraction) of gels, with the absorption or release of
        water, are strongly influenced by the electrical properties of the system, which includes solvent water, bound
        water, and small solutes and ions as well as the polymers. Changes in pH and ionic strength and temperature, and
        the presence of solutes modifying the polymer’s affinity for water, affect the osmotic behavior of the polymer,
        and of gels formed by such polymers. Since the extracellular spaces are mainly filled with solid gels, Guyton’s
        image of simple fluids entering and leaving these “spaces” reveals a major conceptual error, and that error has
        been widely propagated by medical professors. If a person imagines open spaces, interstices, between cells, then
        the question of the fluid pressure in these chambers seems reasonable, and the factors that produce edema will
        be thought of mechanically. But if we call the material between cells the “extracellular matrix,” and recognize
        its relatively solid gel nature, we will see the problem of edema in physical-chemical terms, rather than as a
        problem of simple hydraulics. [*Biographical side-lights<strong>:</strong>&nbsp;Guyton graduated from Ole Miss
        in 1939, got his medical degree from Harvard in 1943, where the department of bacteriology had a grant to study
        the polio virus, and where he worked with people “involved in the war effort,” and then from 1944 to 1946 was
        involved in germ warfare research, mainly at Camp Detrick. Camp Detrick had been established as the center for
        chemical and biological warfare research, and a test site was established in Mississippi in 1943. Guyton’s first
        paper was on aerosol research (published in 1946), and studies at that time were being done to improve the
        spreading of germs in aerosols. Bacterial aerosols were tested on the public in San Francisco, in 1950. Guyton’s
        Harvard colleagues established a polio research lab at Children’s Hospital Medical Center. When he left the
        navy, after working at Camp Detrick, Guyton resumed work at Mass General, and contracted polio before he
        finished his residency.]&nbsp;

        <strong>Idols of medical physiology, foundations and cornerstones for the landfill, some things you shouldn’t
            know about physiology:</strong>
        Genes control the cell, the organism is its genome, the nucleus regulates the cytoplasm. Information flowing
        from the genes produces and maintains the organism. Acquired traits aren’t passed on; mutations are random, the
        genome doesn’t acquire information from the organism or environment, the germ-line is isolated. Physiology is
        bounded by the informational function of genes. The cell is a drop of water containing dissolved chemicals
        enclosed in a membrane.&nbsp; Random diffusion governs energy metabolism, gene induction, and other
        intracellular events. Enzyme reactions occur when dissolved molecules randomly diffusing come into contact with
        a suitable enzyme, as described by the Michaelis-Menton equation. The Donnan equilibrium explains cellular
        electrical behavior, and since ions are distributed across the membrane by active transport, the membrane
        potential is maintained by the expense of metabolic energy. Water is just a peculiar solvent. Water structure
        changes only at extremes of temperature. Cells are perfect osmometers. There are empty spaces between cells. The
        membrane regulates the composition of the cytoplasm, with pumps and pores and channels. Cells must produce
        enough energy to keep the pumps running. Membrane receptors regulate cell responses. Cells are activated by
        receptors, and physical forces for which there are no receptors have no effect on cells except when they are
        above a threshold at which they cause discrete chemical changes. The nervous system is hard-wired. Brain and
        heart cells don’t regenerate. There is an immune system, whose function is to destroy pathogens, with
        inflammation as one of its functions, and its specific reactions are determined by the selection of clones which
        were generated by random mutations; an autonomic nervous system, which regulates visceral reflexes by
        innervating, via receptors, smooth muscle, heart muscle, and glands; an endocrine system, regulated mainly by
        negative feedback, that produces hormone molecules that carry messages to the receptors in certain target
        tissues. Inflammation is produced by germs, and is a defensive reaction of the immune system, and so is good.
        (Sterile inflammation is too confusing to include within the ambit of medical physiology, since it is associated
        with serious harm to the organism. The roles in inflammation of the nervous and endocrine systems and kidneys
        and membrane pumps and osmoregulation aren’t discussed in polite books.) During development, cells are organized
        into systems, and they don’t change their type. In the case of germ cells, their type is determined before they
        exist. Cells are able to undergo only about 50 divisions, and most of those divisions are used up in producing
        an adult organism. The committed nature of the organism’s cells and anatomy make radical functional adaptation
        impossible. Hormones and transmitter substances act only through specific receptor molecules. High energy
        phosphate bonds in compounds such as ATP provide energy to molecular pumps and motors.&nbsp; Molecular forces
        act only locally. Pathologies are primarily local: Inflammations and tumors have local causes, and their effects
        are local. Specific and local treatments are ideal. Circulation is treated as a plumbing problem, tumors as
        clones of defective cells. Consciousness is produced by nervous signals that transmit information, and can be
        compared with the handling of information by computers. Excitation and inhibition are functions of cell
        membranes. Artificial intelligence research into computational and nerve net systems is as much a part of
        research into the physiology of consciousness as computer modeling of feedback systems is a form of research
        into endocrine physiology and immunology. Estrogen, testosterone, thyroid, prolactin, serotonin, adrenalin,
        prostaglandins, etc., are carriers of information in an informational system. Cyclic functions and behaviors are
        governed by genes. The existence of hard-wired informational receptor systems and gene-induction systems is
        necessary because of the random diffusional nature of the other cellular processes and materials.
        <strong><em>Essentially, an organism consists of random inert matter given form and activity by the imposition
                of genetic information accumulated through random mutations.</em></strong>
        (There are really people who still believe those things.)
        <strong><em>A NOTE ON SCIENTIFIC REVOLUTIONS:</em></strong>
        If scientific revolutions depended on "the authorities," then the Copernican revolution would be dated from the
        Pope's apology. The fact that the major journals are controlled by antiscientific dimwits helps to define where
        science exists. Gilbert Ling's revolution in cell physiology has been moved along by the existence of the
        journal, Physiological Chemistry and Physics (and medical NMR). Michael Polanyi, in&nbsp;<strong><em>Personal
                Knowledge,</em></strong>&nbsp;maybe even more than Thomas Kuhn did in his famous book (<em>Structure of
            Scientific Revolutions</em>), helped to solidify the belief that there is a real international monolithic
        "community of science." Even though Polanyi, working "in isolation" in Hungary created his general and elegant
        adsorption isotherm, he didn't teach it to his own students, because of his belief in that community of science,
        which ridiculed his work because it wasn't based on their (false) assumptions about the electrical nature of
        matter. &nbsp; The linguistic and cultural isolation of Hungary and Russia from Europe has permitted them to
        evolve distinctive scientific cultures. C.C. Lindegren, in Cold War in Biology, showed that political forces in
        the U.S. and England suppressed anti-Mendelian ideas by identifying them as subversive, imposing the Central
        Dogma of genetics.&nbsp; But even within an authoritarian national tradition, there are little communities of
        science, where the real development of thought can take place. Perceptions that are clear and useful are the
        real revolutions in science, and the rest of it has to do with social and financial commitments. Even in the
        short time since Kuhn wrote his book, the status of medicine has changed significantly, putting it right up with
        militarism and the energy industry as a source of political and economic power. The authoritarian monolith that
        has been known as the community of science has become increasingly (even in areas such as astronomy, where
        commercial interests aren't so crudely involved) a structure of cultural propaganda maintained by bullying and
        fraud. Since the "normal science" in these authoritarian settings is dedicated to evading the truth, it becomes
        almost a guide to where to look for the truth. It's sort of analogous to the "mystery" of why breast cancer
        mortality is lowest in the poorest part of the U.S., Appalachia, and highest in the richest regions: the medical
        industry goes where the money is, taking death with it. Science, like health, thrives on the neglect of the
        corrupt industry.&nbsp; I have always felt that the cybernetic definition of communication as the transfer of
        something that makes a difference should be applied to speech and writing. As a student and teacher, I saw that
        information which made a difference was the essence of intellectual excitement and growth. But making a
        difference is exactly what university administrators and journal editors don't want.&nbsp; © Ray Peat Ph.D.

            The Progesterone Deceptions
        </h1>

        <p>
            In the 1930s, it was demonstrated that estrogen, even in small doses, produced abortions, and that when it
            is given early enough, even a very small dose will prevent implantation of the fertilized embryo.
            Progesterone was known, by the early 1940s, to protect against the many toxic effects of estrogen, including
            abortion, but it was also known as nature's contraceptive, since it can prevent pregnancy without harmful
            side-effects, by different mechanisms, including prevention of sperm entry into the uterus. That is,
            progesterone prevents the miscarriages which result from excess estrogen (1,2), but if used before
            intercourse, it prevents conception, and thus is a true contraceptive, while estrogen is an abortifacient,
            not a contraceptive.
        </p>
        <p>
            In the 1950s, there was a search for chemicals which would prevent ovulation. According to Carl Djerassi (),
            drug companies were extremely reluctant to risk a religious backlash against their other products, and so
            hesitated to market contraceptives. Obviously, the induction of monthly abortions would have been even
            harder to sell.
        </p>

        <p>
            According to Djerassi (3), "Until the middle 1940s ti was assumed that progesterone's biological activity
            was extremely specific and that almost any alteration of the molecule would diminish or abolish its
            activity." This would obviously discourage interest from the drug companies, who could patent a substance
            which they had chemically modified, but could not patent a simple natural substance. However, many
            substances--even non-steroidal chemicals--were known to have estrogenic action. (4)
        </p>
        <p>
            By 1942, Hans Selye had demonstrated that natural steroids retain their activity when administered orally.
            But every drug company with a steroid patent had an obvious interest in having the public believe that there
            is a reason that the natural steroids cannot be conveniently used. The doctrine that natural steroids are
            destroyed by stomach acid appeared, was promoted, and was accepted--without any supporting evidence. In the
            manufacture of progesterone, the precursor steroid is boiled in hydrochloric acid to free it from its
            glucose residue. No one seriously believed that stomach acid hurts progesterone, except the public--and the
            doctors, who had seen the claim in their medical journals, and had heard it from drug salesmen.
        </p>
        <p>
            The myth stopped the use of the cheap tablets of progesterone, as tablets of the synthetic "progestins" came
            on the market, at a much higher price. Doctors who insisted on using real progesterone were forced to buy it
            in an injectable form. As a result, solubility became an issue. Progesterone is extremely insoluble in
            water, and, though it is vastly more soluble in vegetable oil than in water, it does not stay in solution at
            room temperature even at the low concentration of 1 part in 1000 parts of a typical vegetable oil.
        </p>
        <p>
            When people speak of an allergy to progesterone (or even to penicillin) they generally are not aware of the
            presence of a very toxic solvent.(5) For a time, progesterone was often sold dissolved in benzyl benzoate.
            The Physician's Desk Reference warned of possible allergic reactions to progesterone. Now, it is supposedly
            sold dissolved in vegetable oil, with about 10% benzyl alcohol as--supposedly--a "bacteriostatic agent."
        </p>
        <p>
            Bacteriostatic water contains 0.9% to 1.9% benzyl alcohol, and can irreversibly harm nerves. (6,7) Its use
            in hospitals killed thousands of babies. Awareness of benzyl alcohol's toxicity goes back to 1918 at least;
            it was proposed as an effective insecticide, and was found to be toxic to many animal systems. The safe
            systemic dose (7) is exceeded with an injection of 150 mg. of progesterone, yet the local concentration is
            far higher. It can cause a severe reaction even when used at a lower concentration, in bacteriostatic water.
            (5)
        </p>

        <p>
            Other alcohols, including ethanol, have been used as solvents, but since they (ethanol even more than benzyl
            alcohol) have an affinity for water, the solution decomposes in contact with tissue water.
        </p>
        <p>
            In spite of the toxicity of the vehicle, several beneficial effects can be obtained with injected
            progesterone, in serious conditions such as epilepsy or caner of the breast or uterus. Many researchers have
            commented on the very obvious difficulty of giving very large amounts of progesterone. (8) My comparisons of
            oral progesterone in tocopherol with other forms and methods of administration show a roughly similar
            efficiency for oral and inject progesterone, and about 1/20 the effect for suppositories. Crystals of
            progesterone are visible in the suppositories I have examined, and this material is obviously wasted.
        </p>
        <p>
            An old theory of vitamin E's mechanism of action in improving fertility was that it spares progesterone.(9)
            It is established that some of the effects of vitamin E and progesterone are similar, for example, both
            prevent oxygen waste and appear to improve mitochondrial coupling of phosphorylation with respiration. I
            suspected that if they actually both work at the same mitochondrial site, then they must have a high mutual
            solubility.
        </p>
        <p>
            Knowing the long-standing problem of administering large doses of progesterone without a toxic solvent, I
            applied for and was granted a patent for the composition of progesterone in tocopherol. One of my reasons
            for publishing in the form of patents is that I have had many years of experience in having my discoveries
            taken up by others without acknowledgment, if they are compatible with conventional prejudices. Typically,
            an editor rejects a paper, and then a few months later publishes a very similar paper by someone else. My
            dissertation research, which established that an estrogen excess kills the embryo by suffocation, and that
            progesterone protects the embryo by promoting the delivery of both oxygen and glucose, didn't strike a
            responsive chord in the journals which are heavily influenced by funds from the drug industry.
        </p>
        <p>
            According to a consultant for a major medical journal, the idea ""of dissolving progesterone, a fat soluble
            steroid hormone, in vitamin E which is then incorporated into chylomicrons absorbed via the lymphatics, and
            thus avoids the liver on the so called first pass" "is so simple it is amazing that the pharmaceutical
            companies have not jumped on it." (A more sophisticated writer might have said ""stomped on it.")
        </p>
        <p>
            In the powder form, direct and intimate contact with a mucous membrane allows lipid phase to lipid phase
            transfer of progesterone molecules. Instead of by-passing the liver, much of the progesterone is picked up
            in the portal circulation, where a major part of it is glucuronidated, and made water soluble for prompt
            excretion.
        </p>

        <p>
            Since this glucuronide form cross-reacts to some extent with the ordinary progesterone in the assay process,
            and since 50% of the ordinary free progesterone is carried inside the red blood cells (10,11), and 50% is
            associated with proteins in the plasma, while the glucuronide hardly enters the red blood cells at all, it
            is better to judge by clinical efficacy when comparing different oral forms. My comparisons show several
            times higher potency in the tocopherol composition than in powder form.
        </p>
        <p>
            Since progesterone's use as a drug antedates the 1938 law requiring special federal approval, its legal
            status is similar to that of thyroid hormone. Unfortunately, for both thyroid and progesterone, there is a
            tendency to cut corners for the sake of a bigger profit margin.
        </p>
        <p>
            For example, steroid acetates are generally a little cheaper than the simple natural steroid. Some people
            assume that an acetate or butyrate can be substituted for the steroid itself. This can cause dangerous
            reactions.
        </p>
        <p>
            Medroxyprogesterone acetate is considered a progestin (though it is not supportive of gestation), because it
            modifies the uterus in approximately the wasy progesterone does, but it is luteolytic, and lowers the
            ovaries' production of progesterone while progesterone itself has a positive effect on the corpus luteum,
            stimulating progesterone synthesis. Defining "progestin" in a narrow way allows many synthetics to be sold
            as progestogens, though some of them are strongly estrogenic, allowing them to function as
            contraceptives--it is odd that contraceptives and agents which suppress progesterone synthesis should be
            officially called "supported of pregnancy." It is probably partly the acetate group in the
            medroxyprogesterone acetate molecule which makes it bind firmly to receptors, yet causes it to block the
            enzymes which would normally be involved in progesterone metabolism. (I think testosterone, even, might be a
            safer progestin than medroxyprogesterone acetate.) Pregnenolone acetate similarly blocks the enzymes which
            normally metabolize pregnenolone. (12) In aspirin, it has been found that it is the acetyl group which (by a
            free radical action) blocks an enzyme involved in prostaglandin synthesis.
        </p>
        <p>
            If the category called "progestogens" or "progestins" is to be defined on the basis of a single tissue
            reaction, then it is possible to classify progesterone with the toxic synthetic substances, but then it
            becomes highly deceptive to imply that progesterone is <strong><em>just</em></strong> a progestin, or that
            it has any of the <strong><em>other properties </em></strong>

            of the toxic synthetics, but this continues to be done. The warnings about "progestins causing birth
            defects," for example, cause epileptic women t use conventional anti-seizure drugs (all of which cause birth
            defects) during pregnancy, and to avoid natural progesterone, which generally could control their seizures.
            Thus, a false message attached to progesterone creates precisely the harm it claims to want to prevent. In
            my communications with the regulatory agencies, I have concluded that their attempts to deceive are too
            blatant to ascribe to incompetence. Whether it's the Forest Service the FDA, the principle is the same: The
            regulatory agencies have been captured by the regulated industries.
        </p>
        <p>
            Another place to cut costs is in the tocopherol. Tocopherol acetate does have vitamin E activity, but sine
            it is only about half as efficiently absorbed as the simple tocopherol (13), it is a mistake to save a few
            dollars an ounce, at the expense of losing half of the therapeutic effect. People who have compared natural
            progesterone in natural tocopherols with other compositions have insisted that the other compositions must
            not contain progesterone.
        </p>
        <p>
            The taste of natural vitamin E is stronger than that of the synthetic forms, but since the mixture is
            absorbed by any tissue it contacts, including various parts of the bowel, it can be taken in a capsule. If a
            small amount of olive oil is used with it, absorption through the skin is very rapid. Many women use it
            vaginally, spread onto a diaphragm, to hold it in contact with the membranes. The efficiency of absorption
            by all routes is so high that patients should be warned against its anesthetic effect, until their dosage
            requirement is known approximately. Some physicians prefer concentrations higher than 10%, but the risk of
            accidental drunkenness or anesthesia is higher with the stronger solutions.
        </p>
        <p>
            It is an indication of the tocopherol solution's high availability that medical researchers such as Roy
            Hertz (8), who thought they were administering maximal doses by combining injections with suppositories,
            never mentioned the problem of an anesthetic effect from an overdose. Similarly, it si evidence of the
            extremely poor availability of the micropulverized progesterone that the researchers have administered
            hundreds of milligrams per day, without mentioning the symptoms of an overdose. Because of the difficulties
            involved in scientifically studying the clinical effectiveness of various formulations, I think the most
            practical way of evaluating the effectiveness of different progesterone formulations is to measure the
            amount extractable from the red blood cells, a few hours after the peak serum level has been reached. This
            will reasonably reflect the amounts reaching brain cells, adrenal glands, and the various other cells on
            which progesterone has its therapeutic action.

        <p><strong>PROGESTERONE INFORMATION</strong></p>
        <p>
            Sixty years ago, progesterone was found to be the main hormone produced by the ovaries. Since it was
            necessary for fertility and for maintaining a healthy pregnancy, it was called the "pro-gestational
            hormone," and its name sometimes leads people to think that it isn't needed when you don't want to get
            pregnant. In fact, it is the most protective hormone the body produces, and the large amounts that are
            produced during pregnancy result from the developing baby's need for protection from the stressful
            environment. Normally, the brain contains a very high concentration of progesterone, reflecting its
            protective function for that most important organ. The thymus gland, the key organ of our immune system, is
            also profoundly dependent of progesterone.
        </p>

        <p>
            In experiments, progesterone was found to be the basic hormone of adaptation and of resistance to stress.
            The adrenal glands use it to produce their antistress hormones, and when there is enough progesterone, they
            don't have to produce the potentially harmful cortisol. In a progesterone deficiency, we produce too much
            cortisol, and excessive cortisol causes osteoporosis, aging of the skin, damage to brain cells, and the
            accumulation of fat, especially on the back and abdomen.
        </p>
        <p>
            Experiments have shown that progesterone relieves anxiety, improves memory, protects brain cells, and even
            prevents epileptic seizures. It promotes respiration, and has been used to correct emphysema. In the
            circulatory system, it prevents bulging veins by increasing the tone of blood vessels, and improves the
            efficiency of the heart. It reverses many of the signs of aging in the skin, and promotes healthy bone
            growth. It can relieve many types of arthritis, and helps a variety of immunological problems.
        </p>
        <p>
            If progesterone is taken dissolved in vitamin E, it is absorbed very efficiently, and distributed quickly to
            all of the tissues. If a woman has ovaries, progesterone helps them to regulate themselves and their hormone
            production. It helps to restore normal functioning of the thyroid and other glands. If her ovaries have been
            removed, progesterone should be taken consistently to replace the lost supply. A progesterone deficiency has
            often been associated with increased susceptibility to cancer, and progesterone has been used to treat some
            types of cancer.
        </p>
        <p>
            It is important to emphasize that progesterone is not just the hormone of pregnancy. To use it only "to
            protect the uterus" would be like telling a man he doesn't need testosterone if he doesn't plan to father
            children, except that progesterone is of far greater and more basic physiological significance than
            testosterone. While men do naturally produce progesterone, and can sometimes benefit from using it, it is
            not a male hormone. Some people get that impression, because some physicians recommend combining estrogen
            with either testosterone or progesterone, to protect against some of estrogen's side effects, but
            progesterone is the body's natural complement to estrogen. Used alone, progesterone often makes it
            unnecessary to use estrogen for hot flashes or insomnia, or other symptoms of menopause.
        </p>
        <p>
            When dissolved in vitamin E, progesterone begins entering the blood stream almost as soon as it contacts any
            membrane, such as the lips, tongue, gums, or palate, but when it is swallowed, it continues to be absorbed
            as part of the digestive process. When taken with food, its absorption occurs at the same rate as the
            digestion and absorption of the food.
        </p>
        <a name="3"></a>
        <p>
            <strong>PROGESTERONE SUPPLEMENTATION </strong>
        </p>
        <p>
            SYMPTOMATIC: For tendonitis, bursitis, arthritis, sunburn, etc., progesterone in vitamin E can be applied
            locally after a little olive oil has been put on the skin to make it easier to spread the progesterone
            solution. For migraines, it has been taken orally just as the symptoms begin.
        </p>
        <p>
            FOR PMS: The normal pattern of progesterone secretion during the month is for the ovaries to produce a large
            amount in the 2<sup>nd</sup> two weeks of the menstrual cycle, (i.e., day 14 through day 28) beginning at
            ovulation and ending around the beginning of menstruation, and then to produce little for the following two
            weeks. An average person produces about 30 milligrams daily during the 2<sup>nd</sup> two weeks. The
            solution I have used contains approximately 3 or 4 milligrams of progesterone per small drop. Three to four
            drops, or about 10 to 15 milligrams of progesterone, is often enough to bring the progesterone level up to
            normal. That amount can be taken days 14 through 28 of the menstrual cycle; this amount may be repeated once
            or twice during the day as needed to alleviate symptoms. Since an essential mechanism of progesterone's
            action involves its opposition to estrogen, smaller amounts are effective when estrogen production is low,
            and if estrogen is extremely high, even large supplements of progesterone will have no clear effect; in that
            case, it is essential to regulate estrogen metabolism, by improving the diet, correcting a thyroid
            deficiency, etc. (Unsaturated fat is antithyroid and synergizes with estrogen.)
        </p>
        <p>
            PERIMENOPAUSAL: The symptoms and body changes leading up to menopause are associated with decreasing
            production of progesterone, at a time when estrogen may be at a lifetime high. The cyclic use of
            progesterone, two weeks on, two weeks off, will often keep the normal menstrual cycle going. Three to our
            drops, providing ten or twelve milligrams of progesterone, is typical for a day, but some women prefer to
            repeat that amount. Progesterone is always more effective when the diet contains adequate protein, and when
            thee isn't an excessive amount of unsaturated fat in the diet..
        </p>

        <p>
            POSTMENOPAUSAL: Some women continue the cyclic use of progesterone ater menopause, because the pituitary
            gland and brain may continue to cycle long after menstruation has stopped, and progesterone is an important
            regulator of pituitary and brain function. The cycling pituitary affects the adrenal glands and other
            organs, and progesterone tends to protect against the unopposed actions of prolactin, cortisol, and adrenal
            androgenic hormones. Progesterone's effects on the pituitary apparently contribute to its protective effect
            against osteoporosis, hypertension, hirsutism, etc. But some women prefer to use progesterone without
            interruption after the menopause, for its protective antistress effects. Slender people usually find that
            two or three drops are enough, but this amount may be repeated once or twice as needed to relieve symptoms.
            Adequate protein in the diet and good thyroid function help the body to produce its own progesterone; even
            if the ovaries have been removed, the adrenal glands and brain continue to produce progesterone.
        </p>
        <a name="4"></a>
        <strong>DOSAGE OF PROGESTERONE</strong>
        <p>
            Since progesterone has none of the harmful side effects of other hormones (except for alteration of the
            menstrual cycle if it is taken at the wrong time of month), the basic procedure should be to use it in
            sufficient quantity to make the symptoms disappear, and to time its use so that menstrual cycles are not
            disrupted. This normally means using it only between ovulation and menstruation unless symptoms are
            sufficiently serious that a missed period is not important. The basic idea of giving enough to stop the
            symptoms can be refined by some information on a few of the factors that condition the need for
            progesterone.
        </p>
        <p>
            If a person has an enlarged thyroid gland, progesterone promotes secretion and unloading of the stored
            "colloid," and can bring on a temporary hyperthyroid state. This is a corrective process, and in itself
            isn't harmful. A thyroid supplement should be used to shrink the goiter before progesterone is given. Normal
            amounts of progesterone facilitate thyroid secretion, while a deficiency, with unopposed estrogen, causes
            the thyroid to enlarge. The production of euphoria has been mentioned as a side effect, but I think euphoria
            is simply an indication of a good physiological state. (The history of official medical attitudes toward
            euphoria is a subject that deserves more attention.) Very large doses that are given in vitamin E solution,
            allowing complete absorption, can reach the level that is sometimes achieved late in pregnancy, producing
            both euphoria and a degree of anesthesis. To avoid unexpected anesthesia, the correct dose should be
            determined by taking about 10 mg. at a time allowing it to spread into the membranes of the mouth, and
            repeating the dose after 10 minutes until the symptoms are controlled.
        </p>

        <p>
            An excessive estrogen/progesterone ratio is more generally involved in producing or aggravating symptoms
            than either a simple excess of estrogen or a deficiency of progesterone, but even this ratio is conditioned
            by other factors, including age, diet, other steroids, thyroid, and other hormones. The relative estrogen
            excess seems to act by producing tissue hypoxia (as reported in my dissertation, University of Oregon,
            1972), and this is the result of changes induced by estrogen in alveolar diffusion, peripheral vascular
            changes, and intracellular oxygen wastage.
        </p>
        <p>
            Hypoxia in turn produces edema (as can be observed in the cornea when it is deprived of oxygen, as by a
            contact lens) and hypoglycemia (e.g., diminished ATP acts like insulin), because glycolysis must increase
            greatly for even a small deficiency of oxygen. Elevated blood lactic acid is one sign of tissue hypoxia.
            Edema, hypoglycemia, and lactic academia can also be produced by other "respiratory" defects, including
            hypothyroidism, in which the tissue does not use enough oxygen. In hypoxia, the skin will be bluer (in thin
            places, such as around the eyes), than when low oxygen consumption is the main problem. Low thyroid is one
            cause of excess estrogen, and when high estrogen is combined with low thyroid, the skin looks relatively
            bloodless.
        </p>
        <p>
            Symptoms in cycling women are most common around ovulation and in the premenstrual week, when the
            estrogen/progesterone ratio is normally highest. At puberty, in the early twenties and in the late thirties
            and menopause are the ages when the ratio is most often disturbed--and these are also the ages when thyroid
            disorders are commonest in women.
        </p>
        <p>
            The individual who suffers from one aspect of the progesterone (and/or thyroid) deficiency will tend to
            develop other problems at different times. With cyclic depressions or migraine headaches at age 22, there
            will possibly be breast disease later, and often there will be problems with pregnancy. These people with a
            history of sever symptoms are the ones most likely to have severe problems around menopause. Prenatal
            exposure to poorly balanced hormones seems to predispose the child to later hormone problems.
        </p>
        <p>
            Excess stress (which can block progesterone synthesis and elevate estrogen) may bring on symptoms in someone
            who never had them. Spending a summer in Alaska, with an unusually long day, may relieve the symptoms of a
            chronic sufferer. Dark cloudy winters in England or the Pacific Northwest are powerful stressors, and cause
            lower production of progesterone in women, and testosterone in men. Toxins can produce similar symptoms, as
            can nutritional deficiencies. A very common cause of an estrogen excess is a dietary protein deficiency--the
            liver simply cannot detoxify estrogen when it is under-nourished.
        </p>

        <p>
            With a diet high in protein (e.g., at least 70-100 grams per day, including eggs) and vitamin A (not
            carotene), I have found that the dose of progesterone can be reduced each month. Using thyroid will usually
            reduce the amount of progesterone needed. Occasionally, a woman won't feel any effect even from 100 mg. of
            progesterone; I think this indicates that they need to use thyroid and diet, to normalize their estrogen,
            prolactin, and cortisol.
        </p>
        <p>
            Progesterone stimulates the ovaries and adrenals to produce progesterone, and it also activates the thyroid,
            so one dose can sometimes have prolonged effects. It shouldn't be necessary to keep using progesterone
            indefinitely, unless the ovaries have been removed. In slender post-menopausal women, 10 mg. per day is
            usually enough to prevent progesterone deficiency symptoms.
        </p>
        <p>
            In a 10% solution of progesterone in vitamin E, one drop contains about three milligrams of progesterone.
            Normally, the body produces 10 to 20 milligrams per day. A dose of 3 or 4 drops usually brings the blood
            levels up to the normal range, but this dose can be repeated several times during the day if it is needed to
            control symptoms.
        </p>
        <p>
            For general purposes, it is most economical and effective to take progesterone dissolved in vitamin E
            orally, for example taking a few drops on the lips and tongue, or rubbing it into the gums. (It is good for
            the general health of the gums.) These membranes are very thin, and the progesterone quickly enters the
            blood. When it is swallowed, the vitamin E allows it to be absorbed through the walls of the stomach and
            intestine, and it can be assimilated along with food, in the chylomicrons, permitting it to circulate in the
            blood to all of the organs before being processed by the liver. These droplets are smaller than red blood
            cells, and some physicians seem to forget that red blood cells pass freely through the liver.
        </p>
        <p>
            For the topical treatment of sun damaged skin, or acne, wrinkles, etc. the oil can be applied directly to
            the affected area.

        <h1>Prostate Cancer</h1>
        <p>
            It was noticed several decades ago that estrogen causes the prostate gland to enlarge in experimental
            animals, but by then an oversimplified view of the sex hormones was already well established, that led
            people to say that "estrogen causes the female organs to grow, and testosterone causes the male organs to
            grow."&nbsp; Logically extending this mistaken idea led many of the same people to suppose that the
            "hormones of one sex would inhibit the growth of the reproductive organs of the other sex."
        </p>
        <p>
            When a friend of mine was told he had prostate cancer, though he had had no symptoms, and should receive
            large doses of estrogen, I reviewed the literature, to see whether his doctor might have seen something I
            had neglected.&nbsp; Since that time, I have found it necessary to use quotation marks around the phrases
            "medical research" and "medical science," because there is a certain kind of "research" performed within the
            medical profession which is peculiar to that profession.
        </p>
        <p>
            When I read through the studies cited by the current articles as the basis for using estrogen to treat
            prostate cancer, I saw that the decisive "research" had consisted of mailing a questionnaire to physicians
            asking them if they thought it was reasonable to administer estrogen to these patients on the basis of its
            opposition to testosterone, which was considered to be responsible for the growth of the prostate
            gland.&nbsp; Many physicians answered the questionnaire affirmatively.
        </p>
        <p>
            If the questioner's purpose was to determine his legal status in using a treatment, his research method was
            appropriate, to see whether the treatment seemed reasonable to others in the profession.&nbsp; Legally, a
            physician is safe if he can count on others to testify that his practice is standard.&nbsp; Unfortunately,
            for generations his study of the opinions of his peers became the "evidence" of the value of the estrogen
            treatment.&nbsp; Phrases such as "it is indicated," "treatment of choice," and "standard practice" are used
            in medicine, as part of the pseudo-scientific mystique of the profession.&nbsp; Physicans who attempt to
            base their practice on methods that have a sound scientific basis are likely to find that they are violating
            the norms of their profession.
        </p>
        <p>
            More than 25 years ago, when I started pointing out that deliberate misrepresentation had been involved in
            the continued designation of estrogen as "the female hormone," used as a basis for "hormone replacement
            therapies," I saw that it was hard for people to sustain a critical attitude toward language.&nbsp; Language
            is prior to judgment, law, science, reason.&nbsp; Those who define the terms set the rules.
        </p>
        <p>
            By the mid-1980s, some studies had shown that estrogen treatment didn't prolong the survival of prostate
            cancer patients at all, but it was argued that the patients who received estrogen were happier than those
            who didn't.
        </p>
        <p>
            Apparently, many physicians who were experts in conventional cancer treatment hadn't been impressed by the
            happiness of their patients who were receiving estrogen, because a survey at a conference of physicians
            found that many of them would choose to have no treatment if they learned they had prostate cancer.&nbsp;
            And more recently, there have been recommendations that older patients shouldn't be treated aggressively,
            because their cancers are usually so slow growing that they are likely to die of something else related to
            old age.
        </p>
        <p>
            In spite of the articles I showed my friend, and my warning that estrogen can cause strokes and heart
            attacks, he decided to take the estrogen treatment.&nbsp; Within a few days he began suffering from asthma
            and disturbed sleep.&nbsp; Then he had a series of strokes and died.&nbsp;
        </p>
        <p>
            Since it was known that estrogen treatment was dangerous for men, and that it increases blood clotting and
            vascular spasms, there had to be some overriding belief that led to its general use in treating prostate
            cancer.&nbsp; That belief seems to be that "estrogen, the female hormone, opposes testosterone, the male
            hormone, which is responsible for the growth--and therefore for the cancerization--of the prostate
            gland."&nbsp; Everything is wrong with that sentence, but you can find every part of the belief present and
            functioning in the medical literature.&nbsp; Just to give some context to the association of growth and
            cancerization, I should mention that Otto Warburg observed that all of the carcinogenic factors he studied
            caused&nbsp;<span>tissue atrophy before cancer</span>&nbsp;appeared.&nbsp; Another important contextual
            point is that every hormone does&nbsp;<span>many&nbsp;</span>things, and every endocrine gland produces
            multiple hormones.
        </p>
        <p>
            Since the time of Brown-Sequard and Eugen Steinach, it has been accepted that declining testicular function
            is a common feature of aging, and testosterone was probably the first hormone that was clearly found to
            decrease consistently with aging.&nbsp; (Vermeulen, et al., 1972, 1979.)&nbsp;
        </p>
        <p>
            It has seemed odd to many people that enlargement of the prostate should occur mainly in older men, if
            testosterone is the hormone that causes its growth, and estrogen is antagonistic to its growth.&nbsp; The
            nature of the growth of the old man's prostate is very different from its natural growth in youth.
        </p>
        <p>
            It was also recognized decades ago that estrogen rises in men during old age (Pirke and Doerr, 1975), as it
            rises in stress, disease, malnutrition, and hypothyroidism (which are also associated with old age).&nbsp;
            Estrogen is produced in fat (Siiteri, and MacDonald, 1973, Vermeulen, 1976) which tends to increase with
            age, when thyroid and progesterone are deficient.&nbsp; The conversion of testosterone to estrogen occurs in
            the testicle itself, but this conversion is also inhibited by the favorable hormonal environment of
            youth.<span>&nbsp;&nbsp;</span>The active thyroid hormone, T<sub>3</sub>
            <span><sub>,&nbsp;</sub></span>declines with aging, and this necessarily lowers production of pregnenolone
            and progesterone.&nbsp; Increasingly, in both sexes, it appears that DHEA may rise during stress as a result
            of a deficiency of thyroid, progesterone, and pregnenolone.
        </p>
        <p>
            In 1786, John Hunter reported that castration causes a decrease in the size of the prostate gland, and by
            the end of the 19th century castration was being advocated for treating enlargement of the prostate.&nbsp;
            In aging men, the prostate gland (both central and peripheral zones) atrophies, and it is within the
            atrophic gland that cancer cells can be found.&nbsp; Nodular, noncancerous enlargement may occur, with or
            without cancer.&nbsp; In 1935, an autopsy study showed carcinoma in the prostates of 30% of men by the age
            of 50.&nbsp; Proliferation of ductal and epithelial tissue is closely associated with prostate cancer, a
            situation similar to that of the cancerous or precancerous breast.&nbsp; (Simpson, et al., 1982; Wellings,
            et al., 1975; Jensen, et al., 1976.)&nbsp; The high probability of "epitheliosis" in association with cancer
            was seen in women in their early 40s, and in women over 60. (Simpson, et al.)&nbsp; (Epitheliosis just
            refers to an exaggerated proliferation of epithelial cells, the cells covering all surfaces, including the
            lining of glands, and things as simple as irritation and vitamin A deficiency can cause these cells to
            proliferate.)&nbsp; In the breast, the proliferative epitheliosis is clearly caused by estrogenic
            stimulation.&nbsp; The antagonism between estrogen and vitamin A in controlling epithelial proliferation
            (and possibly other cell types<span>:</span>&nbsp;Boettger-Tong and Stancel, 1995) is clear wherever it has
            been tested<span>;</span>&nbsp;vitamin A restrains epithelial proliferation.&nbsp; (Wherever estrogen is a
            factor in the development of abnormal tissue, vitamin A supplementation would seem beneficial.)
        </p>
        <p>
            <span>&nbsp;</span>In aging women and men, as the breasts and prostate atrophy, their estrogen/antiestrogen
            ratio increases.
        </p>
        <p>
            In men with prostate cancer, the fluid secreted by the prostate contains significantly more estradiol than
            the fluid from men without cancer (Rose, et al., 1984).&nbsp; This is analogous to observations made in
            women with breast cancer.
        </p>
        <p>
            The pituitary hormones have diverse functons, including effects on epithelial tissues, other than their
            "classical" functions.&nbsp; Growth hormone, ACTH (Lostroh and Li, 1957), and ACTH with prolactin (Tullner,
            1963) stimulate prostate growth.&nbsp; Prolactin--which is increased by estrogen--stimulates growth of the
            rat's lateral prostate (Holland and Lee, 1980), and stimulates the growth of human prostate epithelial
            cells&nbsp;<span>in vitro</span>&nbsp;(Syms, et al., 1985).&nbsp; LH (luteinizing hormone) increases when
            progesterone or testosterone is deficient, and growth hormone and prolactin (which are closely associated in
            evolution) both increase under a variety of stressful situations, and with estrogenic
            stimulation.&nbsp;&nbsp;<span>Prostate cancer patients who had higher levels of LH and&nbsp;</span>
            <span>lower testosterone</span>
            <span>&nbsp;died most quickly.&nbsp; (Harper, et al., 1984.)&nbsp; Also, a&nbsp;</span>
            <span>high ratio of testosterone to estradiol or of testosterone to prolactin</span>
            <span>&nbsp;corresponded to better survival (Rannikko, et al., 1981.)&nbsp; Considered separately, patients
                with&nbsp;</span>
            <span>higher testosterone levels had a better prognosis</span>
            <span>&nbsp;than those with lower levels, and patients with lower growth hormone&nbsp;</span>levels did
            better than those with higher growth hormone levels. (Wilson, et al., 1985.)&nbsp; Has anyone ever tried
            testosterone therapy for prostate cancer?&nbsp; Or, more practically, a generalized antiestrogenic therapy,
            using thyroid, progesterone, and pregnenolone?&nbsp; Other drugs (naloxone, bromocriptine,
            gonadotropin-releasing hormone agonists, and anti-growth hormone druges, e.g.) are available to regulate the
            pituitary hormones, and might be useful therapeutically or preventively.&nbsp; (See Blaakaer, et al.,
            1995.)&nbsp; Biskind and Biskind's work (1944) with ovarian tumors might be relevant to both testicular and
            prostate cancer.
        </p>
        <p>
            Abnormal patterns of pituitary hormones reflect stress and hormonal imbalance, but they are also directly
            involved in widespread changes in tissue content of glycoproteins.&nbsp; The prostate is specialized to
            secrete large amounts of mucin.&nbsp; The endocrine physiology of prostate mucin secretion is poorly
            understood, but it is likely that there are interactions between growth-regulatory and secretion-regulatory
            systems.
        </p>
        <p>
            In recent years, prostate cancer has been one of the fastest increasing kinds of cancer, and it isn't
            apparent that increased treatment has had an effect in lowering the death rate.&nbsp; The postwar baby-boom
            (following the baby-bust of the great depression) created an abnormal age-structure of the population, that
            has been used to argue that the war against cancer is being won.&nbsp; Increasing environmental estrogens
            are known to cause many reproductive abnormalities, and their contribution to prostate cancer would get more
            attention if estrogen's role in prostate disease were better known.&nbsp; Environmental estrogens are
            clearly responsible for genital deformities and sterility in many species of wild animals, but when the
            causal link is made between estrogens and human abnormalities, the estrogen industry sends its shills in to
            create controversy and confusion.&nbsp; Even the effects of estrogens in sewage, known for decades, are
            treated as State Secrets:&nbsp; "There had been reports of hermaphroditic fishes in one or two rivers, and
            government investigators had been studying them since the late 1970s.&nbsp;&nbsp;<span>But no one had been
                aware of the work because it was classified."</span>&nbsp;(Lutz, 1996.)
        </p>
        <p>
            Testicular cancer is easy to diagnose, and its incidence has clearly increased (100% in white men, 200% in
            black men) since 1950.&nbsp; Undescended testicles, urethral abnormalities, etc., similar to those seen in
            DES sons and in wild animals, have also increased.&nbsp; So the tremendous increase in the death rate from
            prostate cancer during the same time has a meaningful context.
        </p>
        <p>
            Although the animal studies showed that estrogen treatment promotes enlargement of the prostate, it was
            possible to suppose that the human prostate's growth might be stimulated only by testosterone, until tests
            were done&nbsp;<span>in vitro</span>&nbsp;to determine the effects of hormones on cell division.
        </p>
        <p>
            In human prostate slices, several hormones (including insulin, and probably prolactin) stimulated cell
            division<span>;</span>&nbsp;<span>testosterone did not,</span>&nbsp;under these experimental conditions.
            (McKeehan, et al., 1984.) Contrary to the stereotyped ideas, there are suggestions that supplementary
            androgens could control prostate cancer (Umekita, et al., 1996), and that antagonists to prolactin and
            estrogen might be appropriately used in hormonal therapy (for example, Wennbo, et al., 1997; Lane, et al.,
            1997).
        </p>
        <p>
            By the age of 50, men often show an excess of both prolactin and estrogen, and a deficiency of thyroid and
            testosterone.&nbsp; This is the age at which enlargement of the prostate often becomes noticeable.
        </p>
        <p>
            Estrogen's role in prostate growth and cancerization is clear<span>:</span>&nbsp; "<span>...</span
            >simultaneous treatment of intact...rats with testosterone and estradiol-17beta for 16 weeks consistenly
            induced a putative precancerous lesion, termed dysplasia, in the dorsolateral prostate of all animals.&nbsp;
            Since treatment of rats with androgen alone did not elicit the same response, we concluded that estrogen
            played a critical role in the genesis of this proliferative lesion."&nbsp; (Ho and Yu.)
        </p>
        <p>
            Progesterone and pregnenolone also decline in aging men.&nbsp; Several studies using synthetic progestins
            have shown that they effectively shrink the hypertrophic prostate, and the saw palmetto remedy for prostate
            enlargement has been reported to contain pregnenolone, or something similar to it.&nbsp; These materials
            might be expected to reduce conversion of testosterone or other androgens to estrogen.
        </p>
        <p>
            The prostaglandins were discovered in prostatic fluid, where they occur in significant concentrations.&nbsp;
            They are so deeply involved with the development of cancers of all sorts that aspirin and other
            prostaglandin inhibitors should be considered as a basic part of cancer therapy.&nbsp; The prostaglandins
            have local and systemic effects that promote cancer growth.&nbsp; ("The prostaglandins and related
            eicosanoids synthesized from polyunsaturated fatty acid precursors have been implicated as modulators
            of&nbsp;<span>tumor metastasis, host immunoregulation, tumor promotion, and cell proliferation."</span
            >&nbsp; Hubbard, et al., 1988.)
        </p>
        <p>
            Estrogens cause elevation of free fatty acids, and&nbsp; there are many interactions between the unsaturated
            fatty acids and estrogen, including their metabolism to prostaglandins, and their peroxidation.&nbsp;
            Estrogen's roles as free-radical promoter, DNA toxin, carcinogen, tumor promotor, modifier of tissue growth
            factors, anti-thymic hormone, etc., as well as its local effects on the prostate gland, have to be kept in
            mind.&nbsp; Most of the interest in studying estrogen's contributions to prostate cancer relates to the
            existence of estrogen receptors in various parts of the prostate.&nbsp; While that is interesting, it tends
            to distract attention from the fact that many of estrogen's most important actions don't involve the
            "receptors."&nbsp; A&nbsp;<span>direct excitatory</span>&nbsp;action on prostate cells, and&nbsp;<span
            >indirect</span>&nbsp;actions by way of the pituitary, pancreas, thyroid, adrenal, fatty acids,
            prostaglandins, histamine and circulation are probably essential parts of the cancerization process.
        </p>
        <p>
            The unsaturated fatty acids, but not the saturated fatty acids, free estrogen from the serum proteins that
            bind it, and increase its availability and activity in tissue cells.
        </p>

        <p>
            Thyroid supplementation, adequate animal protein, trace minerals, and vitamin A are the first things to
            consider in the prevention of prostate hypertrophy and cancer.&nbsp; Nutritional and endocrine support can
            be combined with rational anticancer treatments, since there is really no sharp line between different
            approaches that are aimed at achieving endocrine and immunological balance, without harming anything.
        </p>
        <p>
            Avoiding tissue atrophy is very closely related to promoting healthy regeneration.&nbsp; These processes
            require efficient energy production, and an appropriate balance between stimulation and resources.&nbsp;
            Growth hormone is sometimes recommend to correct tissue atrophy, but the evidence seems reasonably clear
            that it is a factor in the promotion of tumefaction of the prostate.&nbsp; The only study I have seen
            suggesting that it might be beneficial in prostatic cancer was a 14 day experiment done in female
            rats.&nbsp; Numerous publications suggest that blocking growth hormone is beneficial in treating prostate
            cancer<span>;&nbsp;</span>in future newsletters I will be discussing the evidence that growth hormone, like
            estrogen, cortisol, and unsaturated fats, tends to promote degenerative changes of aging - <a

                Noble rats by bromocriptine." "We, and others, have previously described the histological changes that
                occur in the prostate gland of intact Noble (NBL) rats following prolonged hormonal treatment.
                Dysplasia, a pre-neoplastic lesion, develops specifically in the dorsolateral prostates (DLPs) of NBL
                rats treated for 16 weeks with a combined regimen of testosterone (T) and estradiol-17beta (E2) (T +
                E2-treated rats).&nbsp;</span>
            <span>Concurrent with DLP dysplasia induction, the dual hormone regimen also elicits hyperprolactinemia, in
                addition to an elevation of nuclear type II estrogen binding sites (type II EBS), no alteration in
                estrogen receptors (ER), and marked epithelial cell proliferation in the dysplastic foci.</span>
            <span>&nbsp;The aim of this study was to investigate whether the dual hormone action is mediated via
                E2-induced hyperprolactinemia. Bromocriptine (Br), at a dose of 4 mg/kg body wt per day, was used to
                suppress pituitary prolactin (PRL) release. Serum PRL levels were lowered from values of 341 +/- 50
                ng/ml in T + E2-treated rats to 32 +/- 10 ng/ml in Br co-treated animals. The latter values were
                comparable to those in untreated control rats. In addition, Br co-treatment effectively inhibited the
                evolution of dysplasia (six out of eight rats)&nbsp;</span>
            <span>and the often associated inflammation</span>
            <span>&nbsp;(five out of eight rats) in most animals. In contrast, Br co-treatment did not suppress the T +
                E2-induced type II EBS elevation nor alter ER levels in the DLPs of these rats, when compared with T +
                E2-treated rats. These data extend the many previous studies that have detailed marked influences

        <p>
            <strong>Protective CO2 and aging</strong>
        </p>The therapeutic effects of increasing carbon dioxide are being more widely recognized in recent years. Even
        Jane Brody, the NY Times writer on health topics, has favorably mentioned the use of the Buteyko method for
        asthma, and the idea of "permissive hypercapnia" during mechanical ventilation, to prevent lung damage from
        excess oxygen, has been discussed in medical journals. But still very few biologists recognize its role as a
        fundamental, universal protective factor. I think it will be helpful to consider some of the ways carbon dioxide
        might be controlling situations that otherwise are poorly understood. The brain has a high rate of oxidative
        metabolism, and so it forms a very large proportion of the carbon dioxide produced by an organism. It also
        governs, to a great extent, the metabolism of other tissues, including their consumption of oxygen and
        production of carbon dioxide or lactic acid. Within a particular species, the rate of oxygen consumption
        increases in proportion to brain size, rather than body weight. Between very different species, the role of the
        brain in metabolism is even more obvious, since the resting metabolic rate corresponds to the size of the brain.
        For example, a cat"s brain is about the size of a crocodile"s, and their oxygen consumption at rest is similar,
        despite their tremendous difference in body size.Stress has to be understood as a process that develops in time,
        and the brain (especially the neocortex and the frontal lobes) organizes the adaptive and developmental
        processes in both the spatial and temporal dimensions. The meaning of a situation influences the way the
        organism responds. For example, the stress of being restrained for a long time can cause major gastrointestinal
        bleeding and ulcerization, but if the animal has the opportunity to bite something during the stress (signifying
        its ability to fight back, and the possibility of escape) it can avoid the stress ulcers. The patterning of the
        nervous activity throughout the body governs the local ability to produce carbon dioxide. When the cortex of the
        brain is damaged or removed, an animal becomes rigid, so the cortex is considered to have a "tonic inhibitory
        action" on the body. But when the nerves are removed from a muscle (for example, by disease or accident), the
        muscle goes into a state of constant activity, and its ability to oxidize glucose and produce carbon dioxide is
        reduced, while its oxidation of fatty acids persists, increasing the production of toxic oxidative fragments of
        the fatty acids, which contributes to the muscle"s atrophy.The organism"s intentions, expectations, or plans,
        are represented in the nervous system as a greater readiness for action, and in the organs and tissues
        controlled by the nerves, as an increase or decrease of oxidative efficiency, analogous to the differences
        between innervated and denervated muscles. This pattern in the nervous system has been called "the acceptor of
        action," because it is continually being compared with the actual situation, and being refined as the situation
        is evaluated. The state of the organism, under the influence of a particular acceptor of action, is called a
        "functional system," including all the components of the organism that participate most directly in realizing
        the intended adaptive action.The actions of nerves can be considered anabolic, because during a stressful
        situation in which the catabolic hormones of adaption, e.g., cortisol, increase, the tissues of the functional
        system are protected, and while idle tissues may undergo autophagy or other form of involution, the needs of the
        active tissues are supplied with nutrients from their breakdown, allowing them to change and, when necessary,
        grow in size or complexity. The brain"s role in protecting against injury by stress, when it sees a course of
        action, has a parallel in the differences between concentric (positive, muscle shortening) and eccentric
        (negative, lengthening under tension) exercise, and also with the differences between innervated and denervated
        muscles. In eccentric exercise and denervation, less oxygen is used and less carbon dioxide is produced, while
        lactic acid increases, displacing carbon dioxide, and more fat is oxidized. Prolonged stress similarly decreases
        carbon dioxide and increases lactate, while increasing the use of fat.Darkness is stressful and catabolic. For
        example, in aging people, the morning urine contains nearly all of the calcium lost during the 24 hour period,
        and mitochondria are especially sensitive to the destructive effects of darkness. Sleep reduces the destructive
        catabolic effects of darkness. During the rapid-eye-movement (dreaming) phase of sleep, breathing is inhibited,
        and the level of carbon dioxide in the tissues accumulates. In restful sleep, the oxygen tension is frequently
        low enough, and the carbon dioxide tension high enough, to trigger the multiplication of stem cells and
        mitochondria.Dreams represent the "acceptor of action" operating independently of the sensory information that
        it normally interacts with. During dreams, the brain (using a system called the Ascending Reticular Activating
        System) disconnects itself from the sensory systems. I think this is the nervous equivalent of
        concentric/positive muscle activity, in the sense that the brain is in control of its actions. The active,
        dreaming phase of sleep occurs more frequently in the later part of the night, as morning approaches. This is
        the more stressful part of the night, with cortisol and some other stress hormones reaching a peak at dawn, so
        it would be reasonable for the brain"s defensive processes to be most active at that time. The dreaming process
        in the brain is associated with deep muscle relaxation, which is probably associated with the trophic
        (restorative) actions of the nerves.In ancient China the Taoists were concerned with longevity, and according to
        Joseph Needham (<em>Science and Civilization in China</em>) their methods included the use of herbs, minerals,
        and steroids extracted from the urine of children. Some of those who claimed extreme longevity practiced
        controlled breathing and tai chi (involving imagery, movement, and breating), typically in the early morning
        hours, when stress reduction is most important. As far as I know, there are no studies of carbon dioxide levels
        in practitioners of tai chi, but the sensation of warmth they typically report suggests that it involves
        hypoventilation.In the 1960s, a Russian researcher examined hospital records of measurements of newborn babies,
        and found that for several decades the size of their heads had been increasing. He suggested that it might be
        the result of increasing atmospheric carbon dioxide. The experiences and nutrition of a pregnant animal are
        known to affect the expression of genes in the offspring, affecting such things as allergies, metabolic rate,
        brain size, and intelligence. Miles Storfer (1999) has reviewed the evidence for epigenetic environmental
        control of brain size and intelligence. The main mechanisms of epigenetic effects or "imprinting" are now known
        to involve methylation and acetylation of the chromosomes (DNA and histones).Certain kinds of behavior, as well
        as nutrition and other environmental factors, increase the production and retention of carbon dioxide. The
        normal intrauterine level of carbon dioxide is high, and it can be increased or decreased by changes in the
        mother"s physiology. The effects of carbon dioxide on many biological processes involving methylation and
        acetylation of the genetic material suggest that the concentration of carbon dioxide during gestation might
        regulate the degree to which parental imprinting will persist in the developing fetus. There is some evidence of
        increased demethylation associated with the low level of oxygen in the uterus (Wellman, et al., 2008). A high
        metabolic rate and production of carbon dioxide would increase the adaptability of the new organism, by
        decreasing the limiting genetic imprints.A quick reduction of carbon dioxide caused by hyperventilation can
        provoke an epileptic seizure, and can increase muscle spasms and vascular leakiness, and (by releasing serotonin
        and histamine) contribute to inflammation and clotting disorders. On a slightly longer time scale, a reduction
        of carbon dioxide can increase the production of lactic acid, which is a promoter of inflammation and fibrosis.
        A prolonged decrease in carbon dioxide can increase the susceptibility of proteins to glycation (the addition of
        aldehydes, from polyunsaturated fat peroxidation or methylglyoxal from lactate metabolism, to amino groups), and
        a similar process is likely to contribute to the methylation of histones, a process that increases with aging.
        Histones regulate genetic activity.With aging, DNA methylation is increased (Bork, et al., 2009). <strong>I
            suggest that methylation stabilizes and protects cells when growth and regeneration aren"t possible (and
            that it"s likely to increase when CO2 isn"t available).
        </strong>Hibernation (Morin and Storey, 2009) and sporulation (Ruiz-Herrera, 1994; Clancy, et al., 2002) appear
        to use methylation protectively.Parental stress, prenatal stress, early life stress, and even stress in
        adulthood contribute to "imprinting of the genes," partly through methylation of DNA and the histones.
        Methionine and choline are the main dietary sources of methyl donors. Restriction of methionine has many
        protective effects, including increased average (42%) and maximum (44%) longevity in rats (Richie, et al.,
        1994). Restriction of methyl donors causes demethylation of DNA (Epner, 2001). <strong></strong>The age
        accelerating effect of methionine might be related to disturbing the methylation balance, inappropriately
        suppressing cellular activity. Besides its effect on the methyl pool, methionine inhibits thyroid function and
        damages mitochondria. The local concentration of carbon dioxide in specific tissues and organs can be adjusted
        by nervous and hormonal activation or inhibition of the carbonic anhydrase enzymes, that accelerate the
        oonversion of CO2 to carbonic acid, H2CO3. The activity of carbonic anhydrase can determine the density and
        strength of the skeleton, the excitability of nerves, the accumulation of water, and can regulate the structure
        and function of the tissues and organs. Ordinarily, carbon dioxide and bicarbonate are thought of only in
        relation to the regulation of pH, and only in a very general way. Because of the importance of keeping the pH of
        the blood within a narrow range, carbon dioxide is commonly thought of as a toxin, because an excess can cause
        unconsciousness and acidosis. But increasing carbon dioxide doesn"t necessarily cause acidosis, and acidosis
        caused by carbon dioxide isn"t as harmful as lactic acidosis.Frogs and toads, being amphibians, are especially
        dependent on water, and in deserts or areas with a dry season they can survive a prolonged dry period by
        burrowing into mud or sand. Since they may be buried 10 or 11 inches below the surface, they are rarely found,
        and so haven"t been extensively studied. In species that live in the California desert, they have been known to
        survive 5 years of burial without rainfall, despite a moderately warm average temperature of their surroundings.
        One of their known adaptations is to produce a high level of urea, allowing them to osmotically absorb and
        retain water. (Very old people sometimes have extremely high urea and osmotic tension.)Some laboratory studies
        show that as a toad burrows into mud, the amount of carbon dioxide in its tissues increases. Their skin normally
        functions like a lung, exchanging oxygen for carbon dioxide. If the toad"s nostrils are at the surface of the
        mud, as dormancy begins its breathing will gradually slow, increasing the carbon dioxide even more. Despite the
        increasing carbon dioxide, the pH is kept stable by an increase of bicarbonate (Boutilier, et al., 1979). A
        similar increase of bicarbonate has been observed in hibernating hamsters and doormice.Thinking about the long
        dormancy of frogs reminded me of a newspaper story I read in the 1950s. Workers breaking up an old concrete
        structure found a dormant toad enclosed in the concrete, and it revived soon after being released. The concrete
        had been poured decades earlier. Although systematic study of frogs or toads during their natural buried
        estivation has been very limited, there have been many reports of accidental discoveries that suggest that the
        dormant state might be extended indefinitely if conditions are favorable. Carbon dioxide has antioxidant
        effects, and many other stabilizing actions, including protection against hypoxia and the excitatory effects of
        intracellular calcium and inflammation (Baev, et al., 1978, 1995; Bari, et al., 1996; Brzecka, 2007; Kogan, et
        al., 1994; Malyshev, et al., 1995).When mitochondria are "uncoupled," they produce more carbon dioxide than
        normal, and the mitochondria produce fewer free radicals. Animals with uncoupled mitochondria live longer than
        animals with the ordinary, more efficient mitochondria, that produce more reactive oxidative fragments. One
        effect of the high rate of oxidation of the uncoupled mitochondria is that they can eliminate polyunsatured
        fatty acids that might otherwise be integrated into tissue structures, or function as inappropriate regulatory
        signals.Birds have a higher metabolic rate than mammals of the same size, and live longer. Their tissues contain
        fewer of the highly unsaturated fatty acids. Queen bees, which live many times longer than worker bees, have
        mainly monounsaturated fats in their tissues, while the tissues of the short-lived worker bees, receiving a
        different diet, within a couple of weeks of hatching will contain highly unsaturated fats.Bats have a very high
        metabolic rate, and an extremely long lifespan for an animal of their size. While most animals of their small
        size live only a few years, many bats live a few decades. Bat caves usually have slightly more carbon dioxide
        than the outside atmosphere, but they usually contain a large amount of ammonia, and bats maintain a high serum
        level of carbon dioxide, which protects them from the otherwise toxic effects of the ammonia. The naked mole
        rat, another small animal with an extremely long lifespan (in captivity they have lived up to 30 years, 9 or 10
        times longer than mice of the same size) has a low basal metabolic rate, but I think measurements made in
        laboratories might not represent their metabolic rate in their natural habitat. They live in burrows that are
        kept closed, so the percentage of oxygen is lower than in the outside air, and the percentage of carbon dioxide
        ranges from 0.2% to 5% (atmospheric CO2 is about 0.038). The temperature and humidity in their burrows can be
        extremely high, and to be very meaningful their metabolic rate would have to be measured when their body
        temperature is raised by the heat in the burrow.When they have been studied in Europe and the US, there has been
        no investigation of the effect of altitude on their metabolism, and these animals are native to the high plains
        of Kenya and Ethiopia, where the low atmospheric pressure would be likely to increase the level of carbon
        dioxide in their tissues. Consequently, I doubt that the longevity seen in laboratory situations accurately
        reflects the longevity of the animals in their normal habitat.Besides living in a closed space with a high
        carbon dioxide content, mole rats have another similarity to bees. In each colony, there is only one female that
        reproduces, the queen, and, like a queen bee, she is the largest individual in the colony. In beehives, the
        workers carefully regulate the carbon dioxide concentration, which varies from about 0.2% to 6%, similar to that
        of the mole rat colony. A high carbon dioxide content activates the ovaries of a queen bee, increasing her
        fertility.Since queen bees and mole rats live in the dark, I think their high carbon dioxide compensates for the
        lack of light. (Both light and CO2 help to maintain oxidative metabolism and inhibit lactic acid formation.)
        Mole rats are believed to sleep very little. During the night, normal people tolerate more CO2, and so breathe
        less, especially near morning, with increased active dreaming sleep. A mole rat has never been known to develop
        cancer. Their serum C-reactive protein is extremely low, indicating that they are resistant to inflammation. In
        humans and other animals that are susceptible to cancer, one of the genes that is likely to be silenced by
        stress, aging, and methylation is p53, a tumor-suppressor gene. If the intrauterine experience, with low oxygen
        and high carbon dioxide, serves to "reprogram" cells to remove the accumulated effects of age and stress, and so
        to maximize the developmental potential of the new organism, a life that"s lived with nearly those levels of
        oxygen and carbon dioxide might be able to avoid the progressive silencing of genes and loss of function that
        cause aging and degenerative diseases.Several diseases and syndromes are now thought to involve abnormal
        methylation of genes. Prader-Willi sydrome, Angelman"s syndrome, and various "autistic spectrum disorders," as
        well as post-traumatic stress disorder and several kinds of cancer seem to involve excess methylation. Moderate
        methionine restriction (for example, using gelatin regularly in the diet) might be practical, but if increased
        carbon dioxide can activate the demethylase enzymes in a controlled way, it might be a useful treatment for the
        degenerative diseases and for aging itself. The low carbon dioxide production of hypothyroidism (e.g., Lee and
        Levine, 1999), and the respiratory alkalosis of estrogen excess, are often overlooked. An adequate supply of
        calcium, and sometimes supplementation of salt and baking soda, can increase the tissue content of CO2.<span

        under conditions of gradually increasing concentration of CO2, decreasing concentration of O2, and external
        cooling at 2--3 degrees seems to be based mainly on changes in concentration of CO2 (ACCORDINGLY, PCO2 and other

        potential role of elevated carbon dioxide (CO2) in improving brain oxygenation in the patients with severe OSA
        syndrome is discussed. CO2 increases oxygen uptake by its influence on the regulation of alveolar ventilation
        and ventilation-perfusion matching, facilitates oxygen delivery to the tissues by changing the affinity of
        oxygen to hemoglobin, and increases cerebral blood flow by effects on arterial blood pressure and on cerebral
        vessels. Recent clinical studies show improved brain oxygenation when hypoxia is combined with hypercapnia.
        Anti-inflammatory and protective against organ injury properties of CO2 may also have therapeutic importance.
        These biological effects of hypercapnia may improve brain oxygenation under hypoxic conditions. This may be
        especially important in patients with severe OSA syndrome.Ageing Res Rev. 2009 Oct;8(4):268-76. Epub 2009 Apr 1.

        PURPOSE: Patients with severe hypothyroidism present unique challenges to anesthesiologists and demonstrate much
        increased perioperative risks. Overall, they display increased sensitivity to anesthetics, higher incidence of
        perioperative cardiovascular morbidity, increased risks for postoperative ventilatory failure and other
        physiological derangements. The previously described physiological basis for the increased incidence of
        postoperative ventilatory failure in hypothyroid patients includes decreased central and peripheral ventilatory
        responses to hypercarbia and hypoxia, muscle weakness, depressed central respiratory drive, and resultant
        alveolar hypoventilation. These ventilatory failures are associated most frequently with severe hypoxia and
        carbon dioxide (CO2) retention. The purpose of this clinical report is to discuss an interesting and unique
        anesthetic presentation of a patient with severe hypothyroidism. CLINICAL FEATURES: We describe an unique
        presentation of ventilatory failure in a 58 yr old man with severe hypothyroidism. He had exceedingly low
        perioperative respiratory rate (3-4 bpm) and minute ventilation volume, and at the same time developed primary
        acute respiratory alkalosis and associated hypocarbia (P(ET)CO2 approximately 320-22 mmHg). CONCLUSION: Our
        patient's ventilatory failure was based on unacceptably low minute ventilation and respiratory rate that was
        unable to sustain adequate oxygenation. His profoundly lowered basal metabolic rate and decreased CO2
        production, resulting probably from severe hypothyroidism, may have resulted in development of acute respiratory
        alkalosis in spite of concurrently diminished minute ventilation.Anal Bioanal Chem. 2008 Jan;390(2):679-88. Epub

        </strong>Sananbenesi F, Fischer A. The orchestrated expression of genes is essential for the development and
        survival of every organism. In addition to the role of transcription factors, the availability of genes for
        transcription is controlled by a series of proteins that regulate epigenetic chromatin remodeling. The two most
        studied epigenetic phenomena are DNA methylation and histone-tail modifications. Although a large body of
        literature implicates the deregulation of histone acetylation and DNA methylation with the pathogenesis of
        cancer, recently epigenetic mechanisms have also gained much attention in the neuroscientific community. In
        fact, a new field of research is rapidly emerging and there is now accumulating evidence that the molecular
        machinery that regulates histone acetylation and DNA methylation is intimately involved in synaptic plasticity
        and is essential for learning and memory. Importantly, dysfunction of epigenetic gene expression in the brain
        might be involved in neurodegenerative and psychiatric diseases. In particular, it was found that inhibition of
        histone deacetylases attenuates synaptic and neuronal loss in animal models for various neurodegenerative
        diseases and improves cognitive function. In this article, we will summarize recent data in the novel field of
        neuroepigenetics and discuss the question why epigenetic strategies are suitable therapeutic approaches for the
        treatment of brain diseases.Ukr Biokhim Zh 1994 Jan-Feb;66(1):109-12. <strong>[Protective effect of sodium

                Regeneration and degeneration: Types of inflammation change with aging</strong>
        </p>
        <p></p>For about 100 years it has been popular to explain the degenerative diseases as the result of mutations
        in the genes, a slow accumulation of "somatic mutations," as opposed to the "germ cell mutations" that are
        involved in Huntington"s chorea and sickle cell anemia. Some people explained all the changes of aging on the
        same basis, but 50 years ago, the somatic mutation theory of aging was clearly shown to be false. The
        gene-mutation theory of cancer is more persistent, but the work of people like Harry Rubin has made it clear
        that functional changes in cells that are becoming cancerous destabilize the chromosomes and cause defects to
        appear in the genes, rather than the reverse.Older ways of understanding aging and degenerative disease are now
        returning to the foreground. The developmental interactions of the organism with its environment, and the
        interactions of its cells, tissues, and organs with each other, have again become the focus of biological aging
        research. In place of the old belief that "we are defined and limited by our genes," the new perspective is
        showing us that we are limited by our environment, and that our environment can be modified. As we react to
        unsuitable environments, our internal environments become limiting for our cells, and instead of renewing
        themselves, repairing damage, and preparing for new challenges, our cells find themselves in blind alleys.
        Looking at aging in this way suggests that putting ourselves into the right environments could prevent aging.A
        bird developing inside its eggshell illustrates the way organs and the environment interact. The chicken created
        a very good environment for the early development of its young. When the egg is formed, it contains everything
        needed to produce a chicken, except for oxygen and a steady warm temperature. But before the chick"s body has
        finished developing, using yolk fat for energy, the glucose contained in the egg has been consumed, and at that
        point the chick"s brain stops growing. A researcher who knew that brain growth in other kinds of animals
        requires glucose, injected glucose (or glycine) into the developing eggs when the original glucose had been
        depleted. The supplemental glucose allowed the chick"s brain to continue growing until it hatched. These chicks
        had larger brains, containing more numerous cells. The same experimenters also found that progesterone increases
        brain size, while corticosterone decreases it. Although the egg is a very good environment for the development
        of chickens, these experiments showed that it isn"t the best that can be achieved. If the hen"s environment had
        been different, it might have been able to provide as much glucose and progesterone as the experimenters did.
        Mammals were able to develop bigger brains than birds, by gestating their offspring internally, allowing a
        continuous supply of nutrients, such as glucose, and hormones such as progesterone. But the environment of the
        mother still can profoundly affect the development of the offspring, by influencing her physiology.Another
        factor involved in developing a large brain is the metabolic rate, which is closely associated with the
        temperature. Birds have larger brains relative to their bodies than reptiles do, and birds maintain a
        consistently high body temperature, sometimes as high as 110 degrees F, while reptiles" temperature varies
        somewhat according to the temperature of their surroundings and their level of activity. Amphibians have much
        lower metabolic rates, and are generally unable to live at the higher temperatures required by reptiles. The
        high metabolic rate of a bird, combined with its development inside an egg, means that compromises are made. The
        high rate of metabolism uses the stored energy rapidly, so the growth of the brain is limited. But their very
        high body temperature maximizes the effectiveness of that brain. Birds, such as owls, parrots, and crows, that
        hatch in a less developed, more dependent condition, are able to continue their brain growth, and have larger
        brains than other birds, such as chickens. In birds and mammals, longevity generally corresponds to brain size
        and metabolic rate. (For example, a pet crow, Tata, died at the age of 59 in 2006 in New York; parrots sometimes
        live more than 100 years.) These (altricious) birds are the opposite of precocious, they preserve embryonic or
        infantile traits into adulthood.For whole organisms or for single cells, development depends on the adequacy of
        the environment. Temperature and the quality of nourishment are important, and by thinking about the other
        special features of the growth processes during gestation, we might be able to find that some of the compromises
        that are customarily made in our more mature lives aren"t necessary. One way of looking at aging is that it"s a
        failure of regeneration or healing, related to changes in the nature of inflammation. In childhood, wounds heal
        quickly, and inflammation is quickly resolved; in extreme old age, or during extreme stress or starvation, wound
        healing is much slower, and the nature of the inflammation and wound closure is different. In the fetus, healing
        can be regenerative and scarless, for example allowing a cleft palate to be surgically corrected without scars
        (Weinzweig, et al., 2002).Fifty years ago, inflammation was seen as a necessary part of the healing process, but
        now it is recognized as a cause of heart disease, diabetes, cancer, and aging itself. During the development of
        the organism, the nature of healing changes, as the nature of inflammation changes. Early in life, healing is
        regenerative or restorative, and there is little inflammation. In adulthood as the amount of inflammation
        increases, healing fails to completely restore lost structures and functions, resulting in scarring, the
        replacement of functional tissue with fibrous tissue. Identifiable changes in the nature of inflammation under
        different conditions can explain some of these losses of healing capacity. Factors that limit inflammation and
        fibrosis, while permitting tissue remodeling, could facilitate regeneration and retard aging.Several cytokines
        (proteins that regulate cell functions) appear at much higher concentrations in adult tissues than in fetal
        tissues (PDGF A, three forms of TGF, IGF 1, and bFGF; Wagner, et al., 2007), and when one of these (TGF-beta1)
        is added to the healing fetus, it produces inflammation and fibrosis (Lanning, et al., 1999). Two
        prostaglandins, PGE2 and PGF2a, potently produce inflammation in fetal rabbits, but not in adult rabbits.
        (Morykwas, et al., 1994).Tissue injury that would produce inflammation in adults causes other signals in the
        fetus that activate repair processes. When a cell is injured or stressed, for example when deprived of oxygen,
        it becomes incontinent, and releases ATP into its surroundings. The extracellular ATP, and its breakdown
        products, ADP, AMP, adenosine, and inorganic phosphate or pyrophosphate, stimulate cells in various ways. ATP
        causes vasodilation, increasing circulation, and usually signals cells to divide, and can activate stem cells
        (Yu, et al., 2010) The lactic acid produced by distressed cells also has signalling effects, including
        vasodilation and stimulated division. Stressed cells digest their own proteins and other structural materials
        (autophagy), and the breakdown products act as signals to guide the differentiation of their replacement cells.
        Mobile phagocytes, ingesting the material of decomposing cells, are essential for guiding tissue restoration. In
        adults, prostaglandins are known to be involved in many of the harmful effects of inflammation. They are formed
        from the polyunsaturated fats, linoleic acid and arachidonic acid, which we are unable to synthesize ourselves,
        so the adult"s exposure to the prostaglandins is influence by diet. Since the fetus is able to synthesize fat
        from glucose, the newborn animal usually contains a high proportion of saturated fats and their derivatives,
        such as stearic acid, oleic acid, and Mead acid, which can be synthesized from glucose or amino acids. Newborn
        calves have very little polyunsaturated fat in their tissues, but even the small percentage of PUFA in milk
        causes its tissues to gradually accumulate a higher percentage of PUFA as it matures. The fatty acids of newborn
        humans, and other non-ruminants, reflect their mothers" diets more closely, but Mead acid is still present in
        human newborns (Al, et al., 1990). In a study of prenatal learning (habituation rate), the experimenters found
        that the relative absence of the supposedly essential fatty acids improved the short term and long term memory
        of the fetus (Dirix, et al., 2009). The size of the baby was found to be negatively associated with the highly
        unsaturated fatty acids DHA and AA (Dirix, et al., 2009), showing a general growth-retarding effect of these
        environmentally derived fats.The embryo or fetus is enclosed in a germ-free environment, so it doesn"t need an
        "immune system" in the ordinary sense, but it does contain phagocytes, which are an essential part of
        development, in the embryo, as well as in the adult (Bukovky, et al., 2000). They are involved in removing
        malignant cells, healing wounds, and remodeling tissues. In adults, the long-chain omega-3 fatty acids such as
        DHA are known to be immunosuppressive, but in tests on monocytes from the umbilical cord blood of newborns, the
        highly unsaturated fatty acids kill the monocytes that are so important for proper development and regeneration
        (Sweeney, et al., 2001), and interfere with signals that govern their migration (Ferrante, et al., 1994). DHA is
        now being sold with many health claims, including the idea that adding it to baby formula will improve their
        eyesight and intelligence. As the consumption of PUFA has increased in the US and many other countries, the
        incidence of birth defects has increased. The formation of excessive amounts of prostaglandin, or killing
        macrophages, among other toxic effects, might be responsible for those visible anatomical changes during growth,
        as well as for the subtler loss of regenerative capacity.In the adult, the PUFA and prostaglandins are known to
        increase collagen synthesis. Serotonin and estrogen, which interact closely with PUFA, promote collagen
        synthesis and fibrosis. In the fetus, hyaluronic acid, rather than collagen, is the main extracellular material
        in wound repair (Krummel, et al., 1987). Both it and its decomposition products have important regulatory
        "signal" functions in wound healing (Gao, et al., 2008), inflammation, and cell differentiation (Krasinski and
        Tch"rzewski, 2007). Prostaglandins also inhibit local cell division (observed in the cornea, Staatz and Van
        Horn, 1980), shifting responsibility for tissue repair to mobile cells, for example stem cells from the blood.
        PUFA also interfere with the turnover of collagen by inhibiting proteolytic enzymes that are necessary for
        tissue remodeling. These are among the changes that characterize scar formation, rather than the scarless
        regeneration that can occur in the fetus. They also occur throughout the body with aging, as part of a
        progressive fibrosis.Besides minimizing dietary PUFA, other things are known that will reduce the fibrosis
        associated with injury, inflammation, or aging. Thyroid hormone, progesterone, and carbon dioxide all reduce
        inflammation while facilitating normal tissue remodeling. Fibrosis of the heart and liver, which are often
        considered to be unavoidably progressive, can be regressed by thyroid hormone, and various fibroses, including
        breast, liver, and mesentery, have been regressed by progesterone treatment.The thyroid hormone is necessary for
        liver regeneration, and the ability of the thyroid gland itself to regenerate might be related to the also great
        ability of the adrenal cortex to regenerate--the cells of these endocrine glands are frequently stimulated, even
        by intrinsic factors such as T3 in the thyroid, and seem to have an intrinsic stem-cell-like quality,
        turning-over frequently. Secretion of stimulating substances is probably one of the functions of macrophages in
        these glands (Ozbek &amp; Ozbek, 2006) The failure to recognize the glands" regenerative ability leads to many
        inappropriate medical treatments. The amount of disorganized fibrous material formed in injured tissue is
        variable, and it depends on the state of the individual, and on the particular situation of the tissue. For
        example, the membranes lining the mouth, and the bones and bone marrow, and the thymus gland are able to
        regenerate without scarring. What they have in common with each other is a relatively high ratio of carbon
        dioxide to oxygen. Salamanders, which are able to regenerate legs, jaw, spinal cord, retina and parts of the
        brain (Winklemann &amp; Winklemann, 1970), spend most of their time under cover in burrows, which besides
        preventing drying of their moist skin, keeps the ratio of carbon dioxide to oxygen fairly high.The regeneration
        of finger tips, including a well-formed nail if some of the base remained, will occur if the wounded end of the
        finger is kept enclosed, for example by putting a metal or plastic tube over the finger. The humidity keeps the
        wound from forming a dry scab, and the cells near the surface will consume oxygen and produce carbon dioxide,
        keeping the ratio of carbon dioxide to oxygen much higher than in normal uninjured tissue. Carbon dioxide is
        being used increasingly to prevent inflammation and edema. For example, it can be used to prevent adhesions
        during abdominal surgery, and to protect the lungs during mechanical ventilation. It inhibits the formation of
        inflammatory cytokines and prostaglandins (Peltekova, et al., 2010, Peng, et al., 2009, Persson &amp; van den
        Linden, 2009), and reduces the leakiness of the intestine (Morisaki, et al., 2009). Some experiments show that
        as it decreases the production of some inflammatory materials by macrophages (TNF: Lang, et al., 2005),
        including lactate, it causes macrophages to activate phagocytic neutrophils, and to increase their number and
        activity (Billert, et al., 2003, Baev &amp; Kuprava, 1997).Factors that are associated with a decreased level of
        carbon dioxide, such as excess estrogen and lactate, promote fibrosis. Adaptation to living at high altitude,
        which is protective against degenerative disease, involves reduced lactate formation, and increased carbon
        dioxide. It has been suggested that keloid formation (over-growth of scar tissue) is less frequent at high
        altitudes (Ranganathan, 1961), though this hasn"t been carefully studied. Putting an injured arm or leg into a
        bag of pure carbon dioxide reduces pain and accelerates healing. In aging, the removal of inactive cells becomes
        incomplete (Aprahamian, et al., 2008). It is this removal of cellular debris that is essential for regenerative
        healing to take place. Degenerating tissue stimulates the formation of new tissue, but this requires adequate
        cellular energy for phagocytosis, which requires proper thyroid function. "Hyperthyroidism" has been shown to
        accelerate the process (Lewin-Kowalik, et al., 2002). The active thyroid hormone, T3, stimulates the removal of
        inactive cells (Kurata, et al., 1980). Regenerative healing also requires freedom from substances that inhibit
        the digestion of the debris. The great decline in proteolytic autophagy that occurs with aging (Del Roso, et
        al., 2003) can be reduced by inhibiting the release of fatty acids. This effect is additive to the antiaging
        effects of calorie restriction, suggesting that it is largely the decrease of dietary fats that makes calorie
        restriction effective (Donati, et al., 2004, 2008).Niacinamide is a nutrient that inhibits the release of fatty
        acids, and it also activates phagocytic activity and lowers phosphate. It protects against the development of
        scars in spinal cord injuries, facilitates recovery from traumatic brain injury, and accelerates healing
        generally. While it generally supports immunity, it"s protective against autoimmunity. It can cause tumor cells
        to either mature or disintegrate, but it prolongs the replicative life of cultured cells, and protects against
        excitotoxicity. The amounts needed seem large if niacinamide is thought of as "vitamin B3," but it should be
        considered as a factor that compensates for our unphysiological exposure to inappropriate fats. Aspirin and
        vitamin E are other natural substances that are therapeutic in "unnaturally" large amounts because of our
        continual exposure to the highly unsaturated plant-derived n-3 and n-6 fats.When animals are made "deficient" in
        the polyunsaturated fatty acids, their wounds heal, with normal or accelerated collagen synthesis, and with more
        vigorous collagen breakdown (Parnham, et al., 1977). Their blood vessels are more resistant, preventing shock
        that would otherwise be caused by many factors. All phases of development, from gestation to aging, are altered
        by the presence of the unsaturated fats, and these effects correspond closely to the loss of the regenerative
        capacity, the ability to replenish and restore tissues. If the very small amounts of polyunsaturated fats
        reaching the fetus can retard growth and brain development (Liu and Borgman, 1977; Borgman, et al., 1975) and
        function, it is apparently acting on some very important biological processes. The toxic effects of PUFA seen in
        the animal studies probably have their equivalent in humans, for example the association of childhood
        hyperactivity with a smaller brain. The incidence of the attention deficit-hyperactivity disorder is increasing
        in the US, somewhat faster among girls than boys (Robison, et al.,2002). In schizophrenic teenagers, the brain
        shrinks, suggesting an interaction of the hormones of puberty with environmental toxins or deficiencies. The
        progressive accumulation of much larger amounts of these fats later in life, especially after the rate of growth
        decreases, could be expected to cause even greater interference with those processes of development and
        function. All tissues age, but the brain might be the least ambiguous organ to consider. The aging brain often
        shrinks, and becomes more susceptible to excitotoxicity, which kills brain cells. Degenerative brain diseases,
        such as Huntington"s chorea and Creutzfeld-Jacob disease, have been compared to the dementia of pellagra, in
        which chorea and other excitatory processes are obvious. (Anti-glutamatergic drugs are beginning to be used
        therapeutically, to restore some inhibitory balance in the degenerating brain.)Pellagra occurs about twice as
        often in women as in men, and this is because estrogen activates an enzyme that alters metabolism of tryptophan,
        blocking the formation of niacin. The alternative products include the excitotoxin, quinolinic acid, and some
        carcinogens.Progesterone inhibits the activity of that enzyme. Progesterone also lowers brain serotonin
        (Izquierdo, et al., 1978), decreases the excitatory carcinogens (Moursi, et al., 1970) and increases the
        formation of niacin (Shibata, et al., 2003) The polyunsaturated fats, DHA, EPA, and linoleic acid activate the
        conversion of tryptophan to quinolinic acid (Egashira, et al., 2003, 2004), and inhibit the formation of niacin
        (Egashira, et al., 1995). <strong></strong>The normal pathway from tryptophan to niacin leads to formation of
        the coenzyme NAD, which is involved in a great variety of cellular processes, notably energy production, the
        maintenance of the cellular differentiated state by regulating gene expression, and the activity of phagocytes.
        Glucose and niacinamide work very closely with each other, and with the thyroid hormone, in the maintenance and
        repair of cells and tissues. When one of these energy-producing factors is lacking, the changes in cell
        functions -- a sort of pre-inflammatory state -- activate corrective processes. Energy depletion itself is an
        excitatory state, that calls for increased fuel and oxygen. But when cells are exposed to PUFA, their ability to
        use glucose is blocked, increasing their exposure to the fats. Saturated fats activate the pyruvate
        dehydrogenase enzyme that is essential for the efficient use of glucose, while PUFA block it. (The MRL mouse
        strain has a high regenerative ability, associated with a retained tendency to metabolize glucose rather than
        fatty acids.) The negative energetic effects of PUFA include interfering with thyroid and progesterone. The
        energy resources are suppressed, at the same time that the inflammatory signals are amplified, and many
        regulatory pathways (including the replenishment of NAD from tryptophan) are diverted.In the fetus, especially
        before the fats from the mother"s diet begin to accumulate, signals from injured tissue produce the changes that
        lead quickly to repair of the damage, but during subsequent life, similar signals produce incomplete repairs,
        and as they are ineffective they tend to be intensified and repeated, and eventually the faulty repair processes
        become the main problem. Although this is an ecological problem, it is possible to decrease the damage by
        avoiding the polyunsaturated fats and the many toxins that synergize with them, while increasing glucose,
        niacinamide, carbon dioxide, and other factors that support high energy metabolism, including adequate exposure
        to long wavelength light and avoidance of harmful radiation. As long as the toxic factors are present, increased
        amounts of protective factors such as progesterone, thyroid, sugar, niacinamide, and carbon dioxide can be used
        therapeutically and preventively. <span style="white-space: pre-wrap"> </span>

        Egashira Y, Murotani G, Tanabe A, Saito K, Uehara K, Morise A, Sato M, Sanada H. Hepatic
        alpha-amino-beta-carboxymuconate-epsilon-semialdehyde decarboxylase (ACMSD; formerly termed picolinic
        carboxylase) [EC4.1.1.45] plays a key role in regulating NAD biosynthesis and the generation of quinolinate
        (quinolinic acid) from tryptophan. Quinolinate is a potent endogenous excitotoxin of neuronal cells. We
        previously reported that ingestion of fatty acids by rats leads to a decrease in their hepatic ACMSD activity.
        However, the mechanism of this phenomenon is not clarified. We previously purified ACMSD and cloned cDNA
        encoding rat ACMSD. Therefore, in this study, we examined the differential effect of fatty acids on ACMSD mRNA
        expression by Northern blot. Moreover, we measured quinolinic acid concentration in rats fed on fatty acid. When
        diets containing 2% level of fatty acid were given to male Sprague-Dawley rats (4 weeks old) for 8 days,
        long-chain saturated fatty acids and oleic acid did not affect ACMSD mRNA expression in the liver.
        Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) strongly suppressed the liver ACMSD mRNA expression.
        In<strong>
            rats fed with high linoleic acid diet for 8 days, serum quinolinic acid was significantly increased as
            compared with the rats fed on a fatty acid-free diet under the condition of the approximately same calorie
            ingestion.</strong> These results suggest that the transcription level of ACMSD is modulated by
        polyunsaturated fatty acids, and suppressive potency of ACMSD mRNA is n-3 fatty acid family&gt;linoleic acid
        (n-6 fatty acid)&gt;saturated fatty acid. Moreover, this study provides the information that a high
        polyunsaturated fatty acid diet affects the production of quinolinic acid in serum by suppressing the ACMSD
        activity.Int J Vitam Nutr Res. 2007 Mar;77(2):142-8. <strong>Dietary protein level and dietary interaction

        study, we examined whether dietary protein level, fatty acid type, namely saturated fatty acid and
        polyunsaturated fatty acid, and their interaction affect serum quinolinic acid concentration in rats." Male
        Sprague-Dawley rats (4-weeks old) were fed with 20% casein + 10% stearic acid diet (20C10S), 20% casein + 10%
        linoleic acid diet (20C10L), 40% casein + 10% stearic acid diet (40C10S), or<strong>
            40% casein + 10% linoleic acid diet (40C10L)
        </strong>for 8 days, and serum quinolinic acid concentration and ACMSD activity were determined. Serum
        quinolinic acid <strong>concentration was significantly increased in the 40C10L</strong>

            RU486, Cancer, Estrogen, and Progesterone.
        </h1>

        Recently many people have been disturbed by reading claims that progesterone can cause cancer, or diabetes, or
        autoimmune diseases, or heart disease, or Alzheimer's disease. A flurry of press conferences, and a few groups
        of "molecular biologists" working on "progesterone receptors," and the results of studies in which Prempro
        (containing a synthetic "progestin") increased breast cancer, have created great confusion and concern, at least
        in the English speaking countries. <p></p>
        <p>
            Wyeth, the manufacturer of Prempro, has been highly motivated to recover their sales and profits that
            declined about 70% in the first two years after the Women's Health Initiative announced its results. When
            billions of dollars in profits are involved, clever public relations can achieve marvelous things.
        </p>
        <p>
            Women and other mammals that are <strong><em>deficient</em></strong> in progesterone, and/or that have an
            excess of estrogen, have a higher than average incidence of cancer. Animal experiments have shown that
            administering progesterone could prevent cancer. Cells in the most cancer-susceptible tissues proliferate in
            proportion to the ratio of estrogen to progesterone. When the estrogen dominance persists for a long time
            without interruption, there are progressive distortions in the structure of the responsive organs--the
            uterus, breast, pituitary, lung, liver, kidney, brain, and other organs--and those structural distortions
            tend to progress gradually from fibroses to cancer.
        </p>
        <p>
            As a result of the early studies in both humans and animals, progesterone was used by many physicians to
            treat the types of cancer that were clearly caused by estrogen, especially uterine, breast, and kidney
            cancers. But by the 1950s, the drug industry had created the myth that their patented synthetic analogs of
            progesterone were medically more effective than progesterone itself, and the result has been that
            medroxyprogesterone acetate and other synthetics have been widely used to treat women's cancers, including
            breast cancer.
        </p>

        <p>
            Unfortunately, those synthetic compounds have a variety of functions unlike progesterone, including some
            estrogenic and/or androgenic and/or glucocorticoid and/or antiprogesterone functions, besides other special,
            idiosyncratic side effects. The rationale for their use was that they were "like progesterone, only better."
            The unpleasant and unwanted truth is that, as a group, they are seriously carcinogenic, besides being toxic
            in a variety of other ways. Thousands of researchers have drawn conclusions about the effects of
            progesterone on the basis of their experiments with a synthetic progestin.
        </p>
        <p>
            The earliest studies of estrogen and progesterone in the 1930s had the great advantage of a scientific
            culture that was relatively unpolluted by the pharmaceutical industry. As described by Carla Rothenberg, the
            massive manipulation of the medical, regulatory, and scientific culture by the estrogen industry began in
            1941. After that, the role of metaphysics, word magic, and epicycle-like models increasingly replaced
            empirical science in endocrinology and cell physiology.
        </p>
        <p>
            As the estrogen industry began losing billions of dollars a year following the 2002 report from the Women's
            Health Initiative regarding estrogen's toxicity, and as it was noticed that progesterone sales had increased
            more than 100-fold, it was clear what had to be done--the toxic effects of estrogen had to be transferred to
            progesterone. For more than 50 years, progesterone was recognized to be antimitotic and anti-inflammatory
            and anticarcinogenic, but suddenly it has become a mitogenic pro-inflammatory carcinogen.
        </p>
        <p>
            Science used to involve confirmation or refutation of published results and conclusions. A different
            experimenter, using the technique described in a publication, would often get a different result, and a
            dialog or disputation would develop, sometimes continuing for years, before consensus was achieved, though
            many times there would be no clear conclusion or consensus.
        </p>

        <p>
            In that traditional scientific environment, it was customary to recognize that a certain position remained
            hypothetical and controversial until some new technique or insight settled the question with some degree of
            clarity and decisiveness. People who cherry-picked studies to support their position, while ignoring
            contradictory evidence, were violating the basic scientific principles of tentativeness and reasonableness.
            Contradictory, as well as confirmatory, data have to be considered.
        </p>
        <p>
            But when a single experiment involves several people working for a year or more, at a cost of a million or
            more dollars, who is going to finance an experiment that "would merely confirm" those results? The newly
            developed techniques for identifying specific molecules are often very elaborate and expensive, and as a
            result only a few kinds of molecule are usually investigated in each experiment. The results are open to
            various interpretations, and most of those interpretations depend on results from other studies, whose
            techniques, results, and conclusions have never been challenged, either. There is no significant source of
            funding to challenge the programs of the pharmaceutical industry.
        </p>
        <p>
            The result is that the pronouncements of the principal investigator, and the repetitions of those
            conclusions in the mass media, create a culture of opinion, without the foundation of multiple confirmations
            that used to be part of the scientific process. The process has taken on many of the features of a cult, in
            which received opinions are repeatedly reinforced by the investment of money and authority. Newspaper
            reporters know that the team of investigators spent two years on their project, and the lead investigator
            wears a white lab coat during the interview, so the reporters don't notice that the investigators'
            conclusion is a non sequitur, supported by chains of non sequiturs.
        </p>
        <p>
            The public gets most of its information about science from the mass media, and the increasingly concentrated
            ownership of the media contributes to the use of scientific news as an adjunct to their main business,
            advertising and product promotion. The pharmaceutical industry spends billions of dollars annually on
            direct-to-consumer advertising, so the big scientific news, for the media, is likely to be anything that
            will increase their advertising revenue.
        </p>

        <p>
            Social-economic cults often simplify the thought processes required by the participants, by inventing a
            scapegoat. The estrogen cult has decided that progesterone will be its scapegoat.
        </p>
        <p>
            Hans Selye argued that steroid hormones should be named by their origin, or by their chemical structural
            names, rather than their effects, because each hormone has innumerable effects. To name a substance
            according to its effects is to predict and to foreordain the discoveries that will be made regarding its
            effects.
        </p>
        <p>
            The common system of hormonal names according to their putative effects has allowed ideology and
            metaphysical ideas to dominate endocrinology. The worst example of metaphysical medicine was the use, for
            more than 50 years, of "estrogen, the female hormone" to treat prostate cancer, in the belief that "male
            hormones" cause the cancer, and that the female hormone would negate it. This word magic led to a vast
            psychotic medical endeavor, that has only recently been reconsidered.
        </p>
        <p>
            Within the scheme of hormones understood according to their names, "hormone receptors" were proposed to be
            the mechanism by which hormones produced their effects. Each hormone had a receptor. If another substance
            bound more strongly than the hormone to its receptor, without producing the effects of the hormone, it was
            called an antihormone.
        </p>

        <p>
            The industry of synthetic hormones used the ideology of unitary hormonal action to identify new substances
            as pharmaceutical hormones, that were always in some way said to be better than the natural hormones--for
            example by being "orally active," unlike natural hormones, supposedly. Physicians docilely went along with
            whatever the drug salesmen told them. If a drug was classified as a "progestin" by a single reaction in one
            animal tissue, then it had a metaphysical identity with the natural hormone, except that it was better, and
            patentable.
        </p>
        <p>
            The natural hormones eventually were assigned any of the toxic properties that were observed for the
            pharmaceutical products "in their class." If synthetic progestins caused heart disease, birth defects, and
            cancer, then the "natural progestin" was assumed to do that, too. It's important to realize the impact of
            logical fallacies on the medical culture.
        </p>

        <p>
            Like the hormones themselves, which metaphysically supposedly acted upon one receptor, to activate one gene
            (or set of genes), the antihormones came to be stereotyped. If a particular hormonal action was blocked by a
            chemical, then that substance became an antagonistic antihormone, and when its administration produced an
            effect, that effect was taken to be the result of blocking the hormone for which it was "the antagonist."
        </p>
        <p>
            The "antiprogesterone" molecule, RU486, besides having some progesterone-like and antiestrogenic properties,
            also has (according to Hackenberg, et al., 1996). some androgenic, antiandrogenic, and antiglucocorticoid
            properties. Experiments in which it is used might have pharmaceutical meaning, but they so far have very
            little clear biological meaning.
        </p>
        <p>
            Adding to the conceptual sloppiness of the "molecular biology" wing of endocrinology, the culture in which
            pharmaceutical products had come to dominate medical ideas about hormones allowed the conventional
            pharmaceutical vehicles to be disregarded in most experiments, both <em>in vitro</em>

            and <em>in vivo</em>. If progesterone was injected into patients mixed with sesame oil and benzyl alcohol,
            then it often didn't occur to animal experimenters to give control injections of the solvent. For <em>in
                vitro</em>
            studies, in a watery medium, oil wouldn't do, so they would use an alcohol solvent, and again often forgot
            to do a solvent control experiment.
        </p>
        <p>
            The importance of the solvent was seen by an experimenter studying the effect of vitamin E on age pigment in
            nerves. It occurred to that experimenter to test the ethyl alcohol alone, and he found that it produced
            almost the same effect as that produced by the solution of alcohol and vitamin E. Workers with hormones
            often just assume that a little alcohol wouldn't affect their system. But when the effects of alcohol by
            itself have been studied, many of the effects produced by very low concentrations happen to be the same
            effects that have been ascribed to hormones, such as progesterone.
        </p>
        <p>
            In some cases, the solvent allows the hormone to crystallize, especially if the solvent is water-miscible,
            and fails to distribute it evenly through the medium and cells as the experimenter assumed would happen, and
            so the experimenter reports that the hormone is not effective in that kind of cell, even though the hormone
            didn't reach the cells in the amount intended.
        </p>

        <p>
            These are four of the common sources of error about progesterone: (1) Saying that progesterone has produced
            an effect which was produced by a different substance. (2) Saying that progesterone is the cause of a
            certain effect, if an "anti-progesterone" chemical prevents that effect. (3) Saying that progesterone caused
            something, when in fact the solvent caused it. And (4) saying that progesterone fails to do something, when
            progesterone hasn't been delivered to the system being studied.
        </p>
        <p>
            Many years ago, experimenters who wanted to minimize the problems involved in administering progesterone in
            toxic solvents found that, with careful effort, progesterone could be transferred to a protein, such as
            albumin, and that the albumin-progesterone complex could be washed to remove the solvent. In this form, the
            progesterone can be delivered to cells in a form that isn't radically different from the form in which it
            naturally circulates in the body. Apparently, the labor involved discourages the widespread use of this
            technique.
        </p>
        <p>
            Although the industry's early generalizations about estrogen and progesterone, defining them as "the female
            hormone" and "the pregnancy hormone," were radically mistaken, some useful generalizations about their
            effects were gradually being built up during the first few decades in which their chemical and physiological
            properties were studied.
        </p>

        <p>
            Estrogen's name, derived from the gadfly, accurately suggests its role as an excitant, getting things
            started. Progesterone's name, relating to pregnancy, is compatible with thinking of it as an agent of
            calming and fulfillment. But these properties show up in every aspect of physiology, and the special cases
            of female estrus and pregnancy can be properly understood only in the larger context, in which, for example,
            progesterone is a brain hormone in both sexes and at all ages, and estrogen is an essential male hormone
            involved in the sperm cell's function and male libido.<em> </em>
        </p>
        <p>
            Progesterone can, without estrogen, create the uterine conditions for implantation of an embryo (Piccini,
            2005, progesterone induces LIF; Sherwin, et al., 2004, LIF can substitute for estrogen), and it has many
            other features that can be considered apart from estrogen, such as its regulation of salts, energy
            metabolism, protein metabolism, immunity, stress, and inflammation, but without understanding its opposition
            to estrogen, there will be no coherent understanding of progesterone's biological meaning.
        </p>
        <p>
            Both estrogen and progesterone are hydrophobic molecules (progesterone much more so than estrogen) which
            bind with some affinity to many components of cells. Certain proteins that strongly bind the hormones are
            called their receptors.
        </p>
        <p>
            Cells respond to stimulation by estrogen by producing a variety of molecules, including the "progesterone
            receptor" protein. When progesterone enters the cell, binding to these proteins, the estrogenic stimulation
            is halted, by a series of reactions in which the estrogen receptors disintegrate, and in which estrogen is
            made water soluble by the activation of enzymes that attach sulfate or a sugar acid, causing it leave the
            cell and move into the bloodstream, and by reactions that prevent its reentry into the cell by inactivating
            another type of enzyme, and that suppress its <em>de novo</em> formation in the cell, and that oxidize it
            into a less active form. Progesterone terminates estrogen's cellular functions with extreme thoroughness.
        </p>

        <p>
            A recent publication in <em>Science </em>
            ("Prevention of Brca1-mediated mammary tumorigenesis in mice by a progesterone antagonist," Poole, et al.,
            Dec. 1, 2006), with associated press conferences, reported an experiment in which a special kind of mouse
            was prepared, which lacked two tumor-suppressing genes called BRCA and p53.
        </p>
        <p>
            One of the functions of the BRCA gene product is to repair genetic damage, and another function is to (like
            progesterone) suppress the estrogen receptor and its functions. Estrogen, and some environmental
            carcinogens, can suppress the BRCA gene product. Estrogen can also turn off the tumor suppressor protein,
            p53. So it is interesting that a group of experimenters chose to produce a mouse that lacked both the normal
            BRCA and p53 genes. They had a mouse that was designed to unleash estrogen's effects, and that modeled some
            of the features of estrogen toxicity and progesterone deficiency.
        </p>
        <p>
            This mouse, lacking an essential gene that would allow progesterone to function normally, probably affecting
            progesterone's ability to eliminate the estrogen receptor, also lacked the tumor suppressor gene p53, which
            is required for luteinization (Cherian-Shaw 2004);<strong>
                in its absence, progesterone synthesis is decreased,</strong>
            <strong>estrogen synthesis is increased.</strong>
        </p>

        <p>
            (Chen, Y, et al., 1999<strong>:</strong> BRCA represses the actions of estrogen and its receptor, and, like
            progesterone, activates the p21 promoter, which inhibits cell proliferation. Aspirin and vitamin D also act
            through p21.)
        </p>
        <p>
            The mutant BRCA gene prevents the cell, even in the presence of progesterone, from turning off estrogen's
            effects the way it should. The antiestrogenic RU486 (some articles below), which has some of progesterone's
            effects (including therapeutic actions against endometrial and breast cancer), appears to overcome some of
            the effects of that mutation.
        </p>
        <p>
            It might have been proper to describe the engineered mouse that lacked both the BRCA and the p53 genes as a
            mouse in which the effects of estrogen excess and progesterone deficiency would be especially pronounced and
            deadly. To speak of progesterone as contributing to the development of cancer in that specially designed
            mouse goes far beyond bad science. However, that study makes sense if it is seen as preparation for the
            promotion of a new drug similar in effect to RU486, to prevent breast cancer.
        </p>
        <p>
            The study's lead author, Eva Lee, quoted by a university publicist, said "We found that progesterone plays a
            role in the development of breast cancer by encouraging the proliferation of mammary cells that carry a
            breast cancer gene." But they didn't measure the amount of progesterone present in the animals. They didn't
            "find" anything at all about progesterone. The "anti-progesterone" drug they used has been used for many
            years to treat uterine, ovarian, and breast cancers, in some cases <em>with</em> progesterone, to intensify
            its effects, and its protective effects are very likely the result of its antiestrogenic and anti-cortisol
            effects, both of which are well established, and relevant. In some cases, it acts like progesterone, only
            more strongly.
        </p>
        <p>
            "Other more specific progesterone blockers are under development," Lee notes. And the article in <em
            >Science</em> magazine looks like nothing more than the first advertisement for one that her husband,
            Wen-Hwa Lee, has designed.
        </p>

        <p>
            According to publicists at the University of California, Irvine, "Lee plans to focus his research on
            developing new compounds that will disrupt end-stage cancer cells. The goal is a small molecule that, when
            injected into the blood stream, will act as something of a biological cruise missile to target, shock and
            awe the cancerous cells." "In this research, he will make valuable use of a breast cancer model developed by
            his wife." "She developed the model, and I will develop the molecule," Lee says. "We can use this model to
            test a new drug and how it works in combination with old drugs."
        </p>
        <p>
            "Previously we blamed everything," Lee says of his eye cancer discovery. "We blamed electricity, we blamed
            too much sausage - but in this case it's clear: It's the gene's fault."
        </p>

        <p>
            The things that these people know, demonstrated by previous publications, but that they don't say in the <em
            >Science</em> article, are very revealing. The retinoblastoma gene (and its protein product), a specialty of
            Wen-Hwa Lee, is widely known to be a factor in breast cancer, and to be responsive to progesterone, RU486,
            and p21. Its links to ubiquitin, the hormone receptors, proteasomes, and the BRCA gene are well known, but
            previously they were seen as linking estrogen to cell proliferation, and progesterone to the inhibition of
            cellular proliferation.
        </p>
        <p>
            By organizing their claims around the idea that RU486 is acting as an antiprogesterone, rather than as a
            progesterone synergist in opposing estrogen, Eva Lee's team has misused words to argue that it is
            progesterone, rather than estrogen, that causes breast cancer. Of the many relevant issues that their
            publication ignores, the absence of measurements of the actual estrogen and progesterone in the animals'
            serum most strongly suggests that the project was not designed for proper scientific purposes.
        </p>
        <p>
            They chose to use techniques that are perfectly inappropriate for showing what they claim to show.
        </p>
        <p>
            In the second paragraph of their article, Poole, et al., say "Hormone replacement therapy with progesterone
            and estrogen, but not estrogen alone, has been associated with an elevation risk in postmenopausal women."
            Aside from the gross inaccuracy of saying "progesterone," rather than synthetic progestin, they phrase their
            comment about "estrogen alone" in a way that suggests an identity of purpose with the estrogen industry
            apologists, who have been manipulating the data from the WHI estrogen-only study, clearly to lay the blame
            on progesterone. (Women who took estrogen had many more surgeries to remove mammographically abnormal breast
            tissue. This would easily account for fewer minor cancer diagnoses; despite this, there were more advanced
            cancers in the estrogen group.)
        </p>
        <p>
            While the Poole, et al., group are operating within a context of new views regarding estrogen, progesterone,
            and cancer, they are ignoring the greater part of contemporary thinking about cancer, a consensus that has
            been growing for over 70 years<strong>:</strong> All of the factors that produce cancer, including breast
            cancer, produce inflammation and cellular excitation.
        </p>
        <p>
            Progesterone is antiinflammatory, and reduces cellular excitation.
        </p>
        <p>
            Even within their small world of molecular endocrinology, thinking in ways that have been fostered by
            computer technology, about gene networks, interacting nodes, and crosstalk between pathways, their model and
            their arguments don't work. They have left out the complexity that could give their argument some weight.
        </p>

        <p>
            The medical mainstream has recognized for 30 years that progesterone protects the uterus against cancer;
            that was the reason for adding Provera to the standard menopausal hormonal treatment. The new claim that
            natural progesterone causes breast cancer should oblige them to explain why the hormone would have opposite
            effects in different organs, but the mechanisms of action of estrogen and progesterone are remarkably
            similar in both organs, even when examined at the molecular level. If "molecular endocrinologists" are going
            to have interpretations diametrically opposed to classical endocrinology (if black is to be white, if apples
            are to fall up), they will have to produce some very interesting evidence.
        </p>
        <p>
            Cancer is a malignant (destructive, invasive) tumor that kills the organism. The main dogma regarding its
            nature and origin is that it differs genetically from the host, as a result of mutations. Estrogen causes
            mutations and other forms of genetic instability, as well as cancer itself. Progesterone doesn't harm genes
            or cause genetic instability.
        </p>
        <p>
            The speculative anti-progesterone school has put great emphasis on the issue of cellular proliferation, with
            the reasoning that proliferating cells are more likely to undergo genetic changes. And synthetic progestins
            often do imitate estrogen and increase cellular proliferation. People like the Lees are asserting as an
            established fact that progesterone increases cellular proliferation.
        </p>
        <p>
            A paper by Soderqvist has been cited as proof that progesterone increases the proliferation of breast cells.
            He saw more mitoses in the breasts during the luteal phase of the menstrual cycle, and said the slightly
            increased mitotic rate was "associated with" progesterone. Of course, estrogen increased at the same time,
            and estrogen causes sustained proliferation of breast cells, while progesterone stimulation causes only two
            cell divisions, ending with the differentiation of the cell. (Groshong, et al., 1997, Owen, et al., 1998)
        </p>

        <p>
            One of the ways that progesterone stops proliferation and promotes differentiation is by keeping the
            retinoblastoma protein in its unphosphorylated, active protective state (Gizard, et al., 2006) The effects
            of estrogen and progesterone on that protein are reciprocal (Chen, et al., 2005). It's hard for me to
            imagine that the Lees don't know about these hormonal effects on Wen-Hwa's retinoblastoma gene product.
        </p>
        <p>
            The inactivation of that protein by hyperphosphorylation is part of a general biological process, in which
            activation of a cell (by injury or nervous or hormonal or other stimulation, including radiation) leads to
            the activation of a large group of about 500 enzymes, phosphorylases, which amplify the stimulation, and
            cause the cell to respond by becoming active in many ways, for example, by stopping the synthesis of
            glycogen, and beginning its conversion to glucose to provide energy for the adaptive responses, that include
            the activation of genes and the synthesis or destruction of proteins. Another set of enzymes, the
            phosphatases, remove the activating phosphate groups, and allow the cell to return to its resting state.
        </p>
        <p>
            The "molecular" endocrinologists and geneticists are committed to a reductionist view of life, the view that
            DNA is the essence, the secret, of life, and that it controls cells through its interactions with smaller
            molecules, such as the hormone receptors.
        </p>
        <p>
            The idea of hormone receptors can be traced directly to the work of Elwood Jensen, who started his career
            working in chemical warfare, at the University of Chicago. Jensen claims that an experiment he did in the
            1950s "caused the demise" of the enzymic-redox theory of estrogen's action, by showing that uterine tissue
            can't oxidize estradiol, and that its only action is on the genes, by way of "the estrogen receptor." But
            the uterus and other tissues do oxidize estradiol, and its cyclic oxidation and reduction is clearly
            involved in some of estrogen's toxic and excitatory effects.
        </p>
        <p>
            For some reason, the military is still interested in hormone receptors. Lawrence National Weapons Laboratory
            (with its giant "predictive science" computer) is now the site of some of the anti-progesterone research.
        </p>
        <p>
            Molecular biologists have outlined a chain of reactions, starting at the cell surface, and cascading through
            a series of phosphorylations, until the genes are activated. The cell surface is important, because cells
            are always in contact with something, and their functions and structure must be appropriate for their
            location. But the reductionist view of a network of phosphorylating enzymes ignores some facts.
        </p>
        <p>
            Glycogen phosphorylase was the first enzyme whose activity was shown to be regulated by structural changes,
            allosterism. The active form is stabilized by phosphorylation, but this process takes seconds or minutes to
            develop, and the enzyme becomes active immediately when the cell is stimulated, for example in muscle
            contraction, within milliseconds. This kind of allosteric activation (or inactivation) can be seen in a
            variety of other enzymes, the cold-labile enzymes. A coherent change of the cell causes coordinated changes
            in its parts. These processes of enzymic regulation are fast, and can occur throughout a cell, practically
            simultaneously. Strict reductionists don't like to talk about them. "Network analysis" becomes irrelevant.
        </p>
        <p>
            While a cell in general is activated by a wave of phosphorylation, certain processes (including glycogen
            synthesis) are blocked. When BRCA1 or retinoblastoma protein is hyperphosphorylated, its anti-estrogenic,
            anti-proliferative functions are stopped. The communication between cells is another function that's stopped
            by injury-induced phosphorylation.
        </p>
        <p>
            Estrogen generally activates phosphorylases, and inactivates phosphatases. Progesterone generally opposes
            those effects.
        </p>
        <p>
            Phosphorylation is just one of the regulatory systems that are relevant to the development of cancer, and
            that are acted on oppositely by estrogen and progesterone. To reduce the explanation for cancer to a gene or
            two or three may be an attractive idea for molecular endocrinologists, but the idea's simplicity is
            delusive.
        </p>
        <p>
            Each component of the cell contributes complexly to the cell's regulatory stability. Likewise, a drug such
            as RU486 complexly modifies the cell's stability, changing thresholds in many ways, some of which synergize
            with progesterone (e.g., supporting the GABA system), others of which antagonize progesterone's effects
            (e.g., increasing exposure to prostaglandins).

            There are other proteins in cells, besides the "hormone receptors," that bind progesterone, and that
            regulate cell functions globally. The sigma receptor, for example, that interacts with cocaine to excite the
            cell, interacts with progesterone to quiet the cell. The sigma receptor is closely related functionally to
            the histones, that regulate the activity of chromosomes and DNA, and progesterone regulates many processes
            that control the histones.

        <p>
            The GABA receptor system, and the systems that respond to glutamic acid (e.g., the "NMDA receptors") are
            involved in the inhibitory and excitatory processes that restrain or accelerate the growth of cancer cells,
            and progesterone acts through those systems to quiet cells, and restrain growth.

            The inhibitor of differentiation, Id-1, is inhibited by progesterone, activated by estrogen (Lin, et al.,
            2000). Proteins acting in the opposite direction, PTEN and p21, for example, are activated by progesterone,
            and inhibited by estrogen.
        </p>
        <p>
            The inflammatory cytokines, acting through the NFkappaB protein to activate genes, are generally oppositely
            regulated by estrogen and progesterone.

            Prostaglandins, platelet activating factor, nitric oxide, peroxidase, lipases, histamine, serotonin,
            lactate, insulin, intracellular calcium, carbon dioxide, osmolarity, pH, and the redox environment are all
            relevant to cancer, and are affected systemically and locally by estrogen and progesterone in generally
            opposing ways.

            About ten years ago, Geron corporation announced that it was developing products to control aging and
            cancer, by regulating telomerase, the enzyme that lengthens a piece of DNA at the end of the chromosomes.
            Their argument was that telomeres get shorter each time a cell divides, and that after about 50 divisions,
            cells reach the limit identified by Leonard Hayflick, and die, and that this accounts for the aging of the
            organism. Cancer cells are immortal, they said, because they maintain active telomerase, so the company
            proposed to cure cancer, by selling molecules to inhibit the enzyme, and to cure aging, by providing new
            enzymes for old people. However, Hayflick's limit was mainly the effect of bad culture methods, and the
            theory that the shortening of telomeres causes aging was contradicted by the finding of longer telomeres in
            some old people than in some young people, and different telomere lengths in different organs of the same
            person.
        </p>
        <p>
            But it's true that cancer cells have active telomerase, and that most healthy cells don't. It happens that
            telomerase is activated by cellular injury, such as radiation, that activates phosphorylases, and that it is
            inactivated by phosphatases. Estrogen activates telomerase, and progesterone inhibits it.

            Molecular endocrinology is very important to the pharmaceutical industry, because it lends itself so well to
            television commercials and corporate stock offerings. Monsanto and the Pentagon believe they can use
            reductionist molecular biology to predict, manipulate, and control life processes, but so far it is only
            their ability to damage organisms that has been demonstrated.
        </p>
        <p>
            Besides the early animal studies that showed experimentally that progesterone can prevent or cure a wide
            variety of tumors, the newer evidence showing that progesterone is a major protective factor against even
            breast cancer, would suggest that dishonest efforts to protect estrogen sales by preventing women from using
            natural progesterone will be causing more women to develop cancer.
        </p>

        <p>
            The recent report that the incidence of breast cancer in the United States fell drastically between 2002 and
            2004, following the great decline in estrogen sales, shows the magnitude of the injury and death caused by
            the falsifications of the estrogen industry--a matter of millions of unnecessary deaths, just in the years
            that I have been working on the estrogen issue. The current campaign against progesterone can be expected to
            cause many unnecessary cancer deaths (e.g., Plu-Bureau, et al., Mauvais-Jarvis, et al.), while distracting
            the public from the culpability of the estrogen industry.

        <p>
            In the 1950s, when the pharmaceutical industry was beginning to promote some new chemicals as diuretics to
            replace the traditional mercury compounds, Walter Kempner"s low-salt "rice diet" began to be discussed in
            the medical journals and other media. The diuretics were offered for treating high blood pressure, pulmonary
            edema, heart failure, "idiopathic edema," orthostatic edema and obesity, and other forms of water retention,
            including pregnancy, and since they functioned by causing sodium to be excreted in the urine, their sale was
            accompanied by advising the patients to reduce their salt intake to make the diuretic more effective.
        </p>

        <p>
            It was clear to some physicians (and to most veterinarians) that salt restriction, especially combined with
            salt-losing diuresis, was very harmful during pregnancy, but that combination became standard medical
            practice for many years, damaging millions of babies.
        </p>
        <p>
            Despite numerous publications showing that diuretics could cause the edematous problems that they were
            supposed to remedy, they have been one of the most profitable types of drug. Dietary salt restriction has
            become a cultural cliché, largely as a consequence of the belief that sodium causes edema and hypertension.
        </p>
        <p>
            Salt restriction, according to a review of about 100 studies (Alderman, 2004), lowers the blood pressure a
            few points. But that generally doesn"t relate to better health. In one study (3000 people, 4 years), there
            was a clear increase in mortality in the individuals who ate less salt. An extra few grams of salt per day
            was associated with a 36% reduction in "coronary events" (Alderman, et al., 1995). Another study (more than
            11,000 people, 22 years) also showed an inverse relation between salt intake and mortality (Alderman, et
            al., 1997).
        </p>
        <p>
            Tom Brewer, an obstetrician who devoted his career to educating the public about the importance of prenatal
            nutrition, emphasizing adequate protein (especially milk), calories, and salt, was largely responsible for
            the gradual abandonment of the low-salt plus diuretics treatment for pregnant women. He explained that
            sodium, in association with serum albumin, is essential for maintaining blood volume. Without adequate
            sodium, the serum albumin is unable to keep water from leaving the blood and entering the tissues. The
            tissues swell as the volume of blood is reduced.
        </p>
        <p>
            During pregnancy, the reduced blood volume doesn"t adequately nourish and oxygenate the growing fetus, and
            the reduced circulation to the kidneys causes them to release a signal substance (renin) that causes the
            blood to circulate faster, under greater pressure. A low salt diet is just one of the things that can reduce
            kidney circulation and stimulate renin production. Bacterial endotoxin, and other things that cause
            excessive capillary permeability, edema, or shock-like symptoms, will activate renin secretion.
        </p>
        <p>
            The blood volume problem isn"t limited to the hypertension of pregnancy toxemia: "Plasma volume is usually
            lower in patients with essential hypertension than in normal subjects" (Tarazi, 1976).
        </p>

        <p>
            Several studies of preeclampsia or toxemia of pregnancy showed that supplementing the diet with salt would
            lower the women"s blood pressure, and prevent the other complications associated with toxemia (Shanklin and
            Hodin, 1979).
        </p>
        <p>
            It has been known for many years that decreasing sodium intake causes the body to respond adaptively,
            increasing the renin-angiotensin-aldosterone system (RAAS). The activation of this system is recognized as a
            factor in hypertension, kidney disease, heart failure, fibrosis of the heart, and other problems. Sodium
            restriction also increases serotonin, activity of the sympathetic nervous system, and plasminogen activator
            inhibitor type-1 (PAI-1), which contributes to the accumulation of clots and is associated with breast and
            prostate cancer. The sympathetic nervous system becomes hyperactive in preeclampsia (Metsaars, et al.,
            2006).
        </p>
        <p>
            Despite the general knowledge of the relation of dietary salt to the RAA system, and its application by
            Brewer and others to the prevention of pregnancy toxemia, it isn"t common to see the information applied to
            other problems, such as aging and the stress-related degenerative diseases.
        </p>
        <p>
            Many young women periodically crave salt and sugar, especially around ovulation and premenstrually, when
            estrogen is high. Physiologically, this is similar to the food cravings of pregnancy. Premenstrual water
            retention is a common problem, and physicians commonly offer the same advice to cycling women that was
            offered as a standard treatment for pregnant women--the avoidance of salt, sometimes with a diuretic. But
            when women premenstrually increase their salt intake according to their craving, the water retention can be
            prevented.
        </p>
        <p>
            Blood volume changes during the normal menstrual cycle, and when the blood volume is low, it is usually
            because the water has moved into the tissues, causing edema. When estrogen is high, the osmolarity of the
            blood is low. (Courtar, et al., 2007; Stachenfeld, et al., 1999). Hypothyroidism (which increases the ratio
            of estrogen to progesterone) is a major cause of excessive sodium loss.
        </p>

        <p>
            The increase of adrenalin caused by salt restriction has many harmful effects, including insomnia. Many old
            people have noticed that a low sodium diet disturbs their sleep, and that eating their usual amount of salt
            restores their ability to sleep. The activity of the sympathetic nervous system increases with aging, so
            salt restriction is exacerbating one of the basic problems of aging. Chronically increased activity of the
            sympathetic (adrenergic) nervous system contributes to capillary leakage, insulin resistance (with increased
            free fatty acids in the blood), and degenerative changes in the brain (Griffith and Sutin, 1996).
        </p>
        <p>
            The flexibility of blood vessels (compliance) is decreased by a low-salt diet, and vascular stiffness caused
            by over-activity of the sympathetic nervous system is considered to be an important factor in hypertension,
            especially with aging.
        </p>
        <p>
            Pregnancy toxemia/preeclampsia involves increased blood pressure and capillary permeability, and an excess
            of prolactin. Prolactin secretion is increased by serotonin, which is one of the substances increased by
            salt restriction, but prolactin itself can promote the loss of sodium in the urine (Ibarra, et al., 2005),
            and contributes to vascular leakage and hypertension.
        </p>
        <p>
            In pregnancy, estrogen excess or progesterone deficiency is an important factor in the harmful effects of
            sodium restriction and protein deficiency. A deficiency of protein contributes to hypothyroidism, which is
            responsible for the relative estrogen excess.
        </p>
        <p>
            Protein, salt, thyroid, and progesterone happen to be thermogenic, increasing heat production and
            stabilizing body temperature at a higher level. Prolactin and estrogen lower the temperature set-point.
        </p>
        <p>
            The downward shift of temperature and energy metabolism in toxemia or salt deprivation tends to slow the use
            of oxygen, increasing the glycolytic use of sugar, and contributing to the formation of lactic acid, rather
            than carbon dioxide. In preeclampsia, serum lactate is increased, even while free fatty acids are
            interfering with the use of glucose.
        </p>

        <p>
            One way of looking at those facts is to see that a lack of sodium slows metabolism, lowers carbon dioxide
            production, and creates inflammation, stress and degeneration. Rephrasing it, sodium stimulates energy
            metabolism, increases carbon dioxide production, and protects against inflammation and other maladaptive
            stress reactions.
        </p>
        <p>
            In recent years, Weissman"s "wear-and-tear" theory of aging, and Pearl"s "rate of living" theory have been
            clearly refuted by metabolic studies that are showing that intensified mitochondrial respiration decreases
            cellular damage, and supports a longer life-span.
        </p>
        <p>
            Many dog owners are aware that small dogs eat much more food in proportion to their size than big dogs do.
            And small dogs have a much greater life expectancy than big dogs, in some cases about twice as long
            (Speakman, 2003).
        </p>
        <p>
            Organisms as different as yeasts and rodents show a similar association of metabolic intensity and
            life-span. A variety of hamster with a 20% higher metabolic rate lived 15% longer than hamsters with an
            average metabolic rate (Oklejewicz and Daan, 2002).
        </p>
        <p>
            Individuals within a strain of mice were found to vary considerably in their metabolic rate. The 25% of the
            mice with the highest rate used 30% more energy (per gram of body weight) than the 25% with the lowest
            metabolic rate, and lived 36% longer (Speakman, et al., 2000).
        </p>
        <p>
            The mitochondria of these animals are "uncoupled," that is, their use of oxygen isn"t directly proportional
            to the production of ATP. This means that they are producing more carbon dioxide without necessarily
            producing more ATP, and that even at rest they are using a considerable amount of energy.
        </p>

        <p>
            One important function of carbon dioxide is to regulate the movement of positively charged alkali metal
            ions, such as sodium and calcium. When too much calcium enters a cell it activates many enzymes, prevents
            muscle and nerve cells from relaxing, and ultimately kills the cell. The constant formation of acidic carbon
            dioxide in the cell allows the cell to remove calcium, along with the small amount of sodium which is
            constantly entering the cell.
        </p>
        <p>
            When there is adequate sodium in the extracellular fluid, the continuous inward movement of sodium ions into
            the resting cell activates an enzyme, sodium-potassium ATPase, causing ATP to break down into ADP and
            phosphate, which stimulates the consumption of fuel and oxygen to maintain an adequate level of ATP.
            Increasing the concentration of sodium increases the energy consumption and carbon dioxide production of the
            cell. The sodium, by increasing carbon dioxide production, protects against the excitatory, toxic effects of
            the intracellular calcium.
        </p>
        <p>
            Hypertonic solutions, containing more than the normal concentration of sodium (from about twice normal to 8
            or 10 times normal) are being used to rescuscitate people and animals after injury. Rather than just
            increasing blood volume to restore circulation, the hypertonic sodium restores cellular energy production,
            increasing oxygen consumption and heat production while reducing free radical production, improves the
            contraction and relaxation of the heart muscle, and reduces inflammation, vascular permeability, and edema.
        </p>
        <p>
            Seawater, which is hypertonic to our tissues, has often been used for treating wounds, and much more
            concentrated salt solutions have been found effective for accelerating wound healing (Mangete, et al.,
            1993).
        </p>
        <p>
            There have been several publications suggesting that increasing the amount of salt in the diet might cause
            stomach cancer, because countries such as Japan with a high salt intake have a high incidence of stomach
            cancer.
        </p>
        <p>
            Studies in which animals were fed popular Japanese foods--"salted cuttlefish guts, broiled, salted, dried
            sardines, pickled radish, and soy sauce"--besides a chemical carcinogen, showed that the Japanese foods
            increased the number of tumors. But another study, adding only soy sauce (with a salt content of about 18%)
            to the diet did not increase the incidence of cancer, in another it was protective against stomach cancer
            (Benjamin, et al., 1991). Several studies show that dried fish and pickled vegetables are carcinogenic,
            probably because of the oxidized fats, and other chemical changes, and fungal contamination, which are
            likely to be worse without the salt. Animals fed dried fish were found to have mutagenic urine, apparently
            as a result of toxic materials occurring in various preserved foods (Fong, et al., 1979).
        </p>

        <p>
            Although preserved foods develop many peculiar toxins, even fresh fish in the diet have been found to be
            associated with increased cancer risk (Phukan, et al., 2006).
        </p>
        <p>
            When small animals were given a milliliter of a saturated salt solution with the carcinogen, the number of
            tumors was increased with the salt. However, when the salt was given with mucin, it had no cancer promoting
            effect. Since the large amount of a saturated salt solution breaks down the stomach"s protective mucus
            coating, the stomach cells were not protected from the carcinogen. Rather than showing that salt causes
            stomach cancer, the experiments showed that a cup or more of saturated salt solution, or several ounces of
            pure salt, shouldn"t be ingested at the same time as a strong carcinogen.
        </p>
        <p>
            Some studies have found pork to be associated with cancer of the esophagous (Nagai, et al., 1982), thyroid
            (Markaki, et al., 2003), and other organs, but an experiment with beef, chicken, or bacon diet in rats
            provides another perspective on the role of salt in carcinogenesis. After being given a carcinogen, rats
            were fed meat diets, containing either 30% or 60% of freeze-dried fried beef, chicken, or bacon. Neither
            beef nor chicken changed the incidence of precancerous lesions in the intestine, but the incidence was
            reduced by 12% in the animals on the 30% bacon diet, and by 20% in rats getting the diet with 60% bacon.
            Salt apparently made the difference.
        </p>
        <p>
            Other protective effects of increased sodium are that it improves immunity (Junger, et al., 1994), reduces
            vascular leakiness, and alleviates inflammation (Cara, et al., 1988). All of these effects would tend to
            protect against the degenerative diseases, including tumors, atherosclerosis, and Alzheimer"s disease. The
            RAA system appears to be crucially involved in all kinds of sickness and degeneration, but the protective
            effects of sodium are more basic than just helping to prevent activation of that system.
        </p>
        <p>
            A slight decrease in temperature can promote inflammation (Matsui, et al., 2006). The thermogenic
            substances--dietary protein, sodium, sucrose, thyroid and progesterone--are antiinflammatory for many
            reasons, but very likely the increased temperature itself is important.
        </p>

        <p>
            A poor reaction to stress, with increased cortisol, can raise the body temperature by accelerating the
            breakdown and resynthesis of proteins, but adaptive resistance to stress increases the temperature by
            increasing the consumption of oxygen and fuel. In the presence of increased cortisol, abdominal fat
            increases, along with circulating fatty acids and calcium, as mitochondrial respiration is suppressed.
        </p>
        <p>
            When mice are chilled, they spontaneously prefer slightly salty water, rather than fresh, and it increases
            their heat production (Dejima, et al., 1996). When rats are given 0.9 per cent sodium chloride solution with
            their regular food, their heat production increases, and their body fat, including abdominal fat, decreases
            (Bryant, et al., 1984). These responses to increased dietary sodium are immediate. Part of the effect of
            sodium involves regulatory processes in the brain, which are sensitive to the ratio between sodium and
            calcium. Decreasing sodium, or increasing calcium, causes the body"s metabolism to shift away from
            thermogenesis and accelerated respiration.
        </p>
        <p>
            Regulating intracellular calcium by increasing the production of carbon dioxide is probably a basic
            mechanism in sodium"s protection against inflammation and excitatory cell damage and degeneration.
        </p>
        <p>
            Cortisol"s suppression of mitochondrial respiration is closely associated with its ability to increase
            intracellular calcium. Cortisol blocks the thermogenic effects of sodium, allowing intracellular calcium to
            damage cells. With aging, the tissues are more susceptible to these processes.
        </p>
        <p>
            The thermogenic effects of sodium can be seen in long-term studies, as well as short. A low-sodium diet
            accelerates the decrease in heat production that normally occurs with aging, lowering the metabolic rate of
            brown fat and body temperature, and increasing the fat content of the body, as well as the activity of the
            fat synthesizing enzyme (Xavier, et al., 2003).
        </p>
        <p>
            Activation of heat production and increased body temperature might account for some of the GABA-like
            sedative effects of increased sodium. Increasing GABA in the brain increases brown fat heat production
            (Horton, et al., 1988). Activation of heat production by brown fat increases slow wave sleep (Dewasmes, et
            al., 2003), the loss of which is characteristic of aging. (In adult humans, the skeletal muscles have
            heat-producing functions similar to brown fat.)
        </p>

        <p>
            Now that inflammation is recognized as having a central role in the degenerative diseases, the fact that
            renin, angiotensin, and aldosterone all contribute to inflammation and are increased by a sodium deficiency,
            should arouse interest in exploring the therapeutic uses of sodium supplementation, and the integrated use
            of all of the factors that normally support respiratory energy production, especially thyroid and
            progesterone. Progesterone"s antagonism to aldosterone has been known for many years, and the synthetic
            antialdosterone drugs are simply poor imitations of progesterone.
        </p>
        <p>
            But the drug industry is interested in selling new drugs to block the formation and action of each of the
            components of the RAAS, rather than an inexpensive method (such as nutrition) to normalize the system.

            "Three years before Prozac received approval by the US Food and Drug Administration in late 1987, the German
            BGA, that country's FDA equivalent, had such serious reservations about Prozac's safety that it refused to
            approve the antidepressant based on Lilly's studies showing that previously nonsuicidal patients who took
            the drug had a fivefold higher rate of suicides and suicide attempts than those on older antidepressants,
            and a threefold higher rate than those taking placebos."

        <p>
            "Using figures on Prozac both from Lilly and independent research, however, Dr. David Healy, an expert on
            the brain's serotonin system and director of the North Wales Department of Psychological Medicine at the
            University of Wales, estimated that "probably 50,000 people have committed suicide on Prozac since its
            launch, over and above the number who would have done so if left untreated."

            Anyone who has been reading the mass media and watching television in recent decades is familiar with the
            use of tryptophan as an antidepressant. Tryptophan is easily converted to serotonin and melatonin in the
            body. The most popular kind of antidepressant, the "serotonin reuptake inhibitor", is said to act by
            increasing the action of serotonin in the brain. Many people have read articles in popular science magazines
            explaining that a deficiency of serotonin can cause depression, suicide, and aggression. Estrogen is often
            said to achieve its "wonderful" effects by increasing the effects of serotonin.
        </p>
        <p>
            Reserpine is an ancient tranquilizer, derived from a plant used in India for centuries. It has a powerful
            tranquilizing action, has been used to treat hypertension, and was found to be an antidepressant (Davies and
            Shepherd, 1955). It lowers the concentration of serotonin in the brain and other tissues. Isoniazid, an
            antidepressant that came into use in the 1950s, is effective, but it probably has no effect on serotonin.
            When those drugs were popular, serotonin wasn"t recognized as a "neurotransmitter." It wasn"t until the
            1960s that our present set of doctrines regarding serotonin"s effects on mood and behavior came into being.
        </p>
        <p>
            Serotonin research is relatively new, but it rivals estrogen research for the level of incompetence and
            apparent fraudulent intent that can be found in professional publications.
        </p>
        <p>
            This is partly because of the involvement of the drug industry, but the U.S. government also played a role
            in setting a pattern of confused and perverse interpretation of serotonin physiology, by its policy of
            denigrating and incriminating LSD, a powerful serotonin (approximate) antagonist, by any means possible, for
            example claiming that it causes genetic damage and provokes homicidal or suicidal violence. The issue of
            genetic damage was already disproved in the 1960s, but this was never publicly acknowledged by the National
            Institutes of Mental Health or other government agency. The government"s irresponsible actions helped to
            create the drug culture, in which health warnings about drugs were widely disregarded, because the
            government had been caught in blatant fraud. In more recent years, government warnings about tryptophan
            supplements have been widely dismissed, because the government has so often lied. Even when the public
            health agencies try to do something right, they fail, because they have done so much wrong.
        </p>
        <p>
            In animal studies LSD, and other anti-serotonin agents, increase playfulness and accelerate learning, and
            cause behavioral impairment only at very high doses. While reserpine was used medically for several decades,
            and was eventually found to have harmful side effects, medical research in LSD was stopped before its actual
            side effects could be discovered. The misrepresentations about LSD, as a powerful antiserotonin agent,
            allowed a set of cultural stereotypes about serotonin to be established. Misconceptions about serotonin and
            melatonin and tryptophan, which are metabolically interrelated, have persisted, and it seems that the drug
            industry has exploited these mistakes to promote the "new generation" of psychoactive drugs as activators of
            serotonin responses. If LSD makes people go berserk, as the government claimed, then a product to amplify
            the effects of serotonin should make people sane.
        </p>
        <p>
            The "serotonin reuptake inhibitors" are called the "third generation" of antidepressants. The monoamine
            oxidase (MAO) inhibitors, that came into use in the 1950s, are called the "first generation." When their
            patents expire on a "generation" of drugs, the drug companies find reasons for claiming that the new drugs
            are better. Every doctor in the country seems to know that the old MAO-inhibitors are dangerous because they
            can raise blood pressure if you eat certain kinds of cheese while taking them. <strong>In fact, statistics
                show that they are safer than the new generation of antidepressants.</strong> It is hardly possible for
            a physician to prescribe the most appropriate drug, because the medical licensing boards are thoroughly
            indoctrinated by the drug companies, to believe that the safest and most effective drugs are those whose
            patents are still in force.
        </p>
        <p>
            While it is true that the newer antidepressants increase the actions of serotonin, it is not true that this
            explains their antidepressant action. This is a culturally conditioned promotional construction. Since
            different antidepressants increase, decrease, or don"t affect the actions of serotonin, a radically new kind
            of theory of depression and the antidepressants is needed. Theories based on "transmitter" substances and
            "receptors" are favored by the drug industry, but that kind of thinking is hardly better than the belief in
            demons and their exorcism. If an herbal tea cures depression because the demon doesn"t like its smell, at
            least the patient never has to abandon a remedy because a tea patent has expired.
        </p>
        <p>
            In the world of "neurotransmitters" and "receptors," there is ample room for the development of speculative
            mechanisms of drug action. Serotonin is regulated by the rate of its synthesis and degradation, by its
            uptake, storage, and release, and by its transporters, and its effects are modified by a great variety of
            receptors, by the number of these receptors, and by their binding affinities and competitive binders.
            "Different receptors" are defined by the effects of chemicals other than serotonin; this means that
            serotonin itself hypothetically gains some of the properties of every substance that shows some binding
            competition with serotonin. This complexity*note 1 has made it possible to argue that a given condition is
            caused by either an excess or a deficiency of serotonin.
        </p>
        <p>
            The drug companies like to call some of their new products SSRI, "selective serotonin reuptake inhibitors,"
            meaning that they don"t indiscriminately increase all the biogenic amines, the way the old MAO inhibitors
            supposedly did. Every drug does many things, each a little differently, so it"s technically true to say that
            they "selectively" do this or that. But the term "antidepressant," as distinguished from "tranquilizer,"
            says that the drug is intended to relieve depression. Injecting serotonin never does that, but sometimes
            adrenalin or dopamine does, and these "SSRI" drugs increase the activities of those other amines enough that
            those changes could explain the altered mood, if it weren"t for the need to speak of a "new generation of
            drugs." Injecting serotonin, or increasing its activity, can cause sedation, helplessness, or apathy, but
            these drugs have that effect only some of the time. Therefore, they aren"t called tranquilizers. If they
            were really selective for serotonin, they just wouldn"t be antidepressants. And chemicals that antagonize
            serotonin do seem to function as antidepressants (Martin, et al., 1992). When an SSRI is used to treat
            irritability and aggression, it is appropriate to call it a tranquilizer. When drugs are used empirically,
            without really understanding the disease or the drug, classifications, descriptions, and names are
            subjective. The serotonin situation reminds me of the history of DES: For almost twenty years, this
            synthetic estrogen was marketed for the prevention of abortions; then it came out as the "morning after"
            contraception/abortion pill. "If increasing serotonin isn"t the cure, then maybe decreasing serotonin will
            be the cure."
        </p>
        <p>
            To begin to understand serotonin, it"s necessary to step back from the culture of neurotransmitters, and to
            look at the larger biological picture.
        </p>
        <p>
            Serotonin and estrogen have many systematically interrelated functions, and women are much more likely to
            suffer from depression than men are. Serotonin and histamine are increased by estrogen, and their activation
            mimics the effects of estrogen. Serotonin is closely involved in mood disorders, but also in a great variety
            of other problems that affect women much more frequently than men. These are probably primarily energy
            disorders, relating to cellular respiration and thyroid function. Liver disease and brain disease, e.g.,
            Alzheimer"s disease, are both much more common in women than in men, and serotonin and estrogen strongly
            affect the energetic processes in these organs. Liver disease can increase the brain"s exposure to
            serotonin, ammonia, and histamine. It isn"t just a coincidence that these three amines occur together and
            are neurotoxic; they are all stress-related substances, with natural roles in signaling and regulation.
        </p>
        <p>
            There are good reasons for thinking that serotonin contributes to the nerve damage seen in multiple
            sclerosis and Alzheimer"s disease.
        </p>
        <p>
            The high incidence of multiple sclerosis in women, and its onset during their reproductive years, is well
            known. The number of brain lesions is associated with the ratio of estrogen to progesterone. Estrogen
            activates mast cells to release histamine and serotonin, and activated mast cells can produce brain edema
            and demyelination. Blood clots have been microscopically associated with brain lesions like those in
            multiple sclerosis, and the platelets in clots release neurotoxic serotonin.
        </p>
        <p>
            In Parkinson"s disease, the benefits seen from increasing the concentration of dopamine could result from
            dopamine"s antagonism to serotonin; anti-serotonin drugs can alleviate the symptoms, and 5-hydroxytryptophan
            can worsen the symptoms (Chase, et al., 1976). Other movement disorders, including akathisia and chorea, can
            be produced by serotonin. In autism, repetitive motions are a common symptom, and serotonin is high in the
            blood serum and platelets of autistic children and their relatives. Irritable bowel syndrome, another kind
            of "movement disorder," can be treated effectively with anti-serotonin agents. This syndrome is very common
            in women, with premenstrual exacerbations, when estrogen is highest. One of the side effects of oral
            contraceptives is chorea, uncontrollable dancing movements. Some research has found increased serotonin in
            people with Huntington"s chorea (Kish, et al., 1987), and positive results with bromocriptine have been
            reported (Agnoli, et al., 1977).

            The neurosteroid, allopregnanolone, for which progesterone is the precursor, facilitates the inhibitory
            action of GABA, which is known to be deficient in some disorders of mood and movement. This suggests that
            progesterone will be therapeutic in the movement disorders, as it is in various mood problems. Progesterone
            has some specific antiserotonin actions (e.g., Wu, et al., 2000).

            The "serotonin reuptake inhibitors" "are presumed" to have the same effect on the brain that they have on
            blood platelets. They inhibit the ability of platelets to retain and concentrate serotonin, allowing it to
            stay in the plasma. This uptake-inhibited condition is a model of the platelet behavior seen in multiple
            sclerosis and Alzheimer"s disease.

            Serotonin and its derivative, melatonin, are both involved in the biology of torpor and hibernation.
            Serotonin inhibits mitochondrial respiration. Excitoxic death of nerve cells involves both the limitation of
            energy production, and increased cellular activation. Serotonin has both of these actions.
        </p>
        <p>
            In hibernating animals, the stress of a declining food supply causes increased serotonin production. In
            humans and animals that don"t hibernate, the stress of winter causes very similar changes. Serotonin lowers
            temperature by decreasing the metabolic rate. Tryptophan and melatonin are also hypothermic. In the winter,
            more thyroid is needed to maintain a normal rate of metabolism.
        </p>
        <p>
            Increased serotonin interferes with the consolidation of learning. Hypothermia has a similar effect. Since
            estrogen increases serotonergia, and decreases body temperature, these effects help to explain the
            long-observed interference of estrogen with learning.

        <p>
            Although ammonia, produced by fatigue or liver inefficiency, creates torpor, it can also cause convulsions.
            It synergizes with serotonin, and both of these promote excitotoxicity.

            Serotonin"s other names include thrombotonin, thrombocytin, enteramine, and 5-HT, its chemical name
            (5-hydroxytryptamine). These historical names derive from its role in the intestine and in blood vessels. In
            1951, it was discovered that enteramine and thrombotonin were a single substance, and its involvement in
            circulatory disease, especially hypertension and vascular spasms, was the focus of research. (The increase
            in the number of "cardiovascular events" recently seen in the study of women using estrogen is what might be
            expected from something which increases serotonin dominance.) It causes vasoconstriction and vasospasm, and
            promotes clotting, when it"s released from platelets. Especially when it is released from mast cells, it is
            considered to be an inflammatory mediator, along with histamine. Edema, bronchoconstriction,
            immunosuppression, and joint swelling are produced by the release of serotonin from platelets or other
            cells. As inflammatory mediators, serotonin and histamine are directly involved in asthma, hives,
            gastrointestinal damage from alcohol, nerve cell damage, edema, and shock.
        </p>
        <p>
            The broadly protective effects of antihistamine drugs have been energetically exploited by the drug industry
            for fifty years. Why haven"t antiserotonin drugs been similarly emphasized?
        </p>
        <p>
            Research on LSD and its derivatives led to drugs such as bromocriptine, which oppose the effects of
            histamine and estrogen. Some of bromocriptine"s effects are clearly antagonistic to serotonin, though
            bromocriptine is usually called a "dopamine agonist"; dopamine is pretty generally a serotonin antagonist.
            Methysergide, a related drug with antiserotonin activity, is effective in protecting the brain from the
            effects of strokes. But there is a general disinclination to understand the broad biological meaning of
            these effects.
        </p>
        <p>
            I think the corrupt campaign against LSD played a large role in this: If the therapeutic value of LSD and
            related drugs (e.g., methysergide) with expired patents,*note2 used as antiserotonin agents, became widely
            known, the existing system of power and profit would be threatened. The war on drugs has always had its
            ulterior motives,including justifying domestic and foreign interventions in issues that have nothing to do
            with drugs. And in the case of the serotonin/antiserotonin mythology, this "war" has been rewarding to the
            drug industry--Lilly makes over $2 billion annually on Prozac. Each suicide caused by Prozac would appear to
            be balanced by several hundred thousand dollars earned by the corporation. If the war on drugs were serious,
            this would be a good place to start. And in weighing what corporate punishments might be appropriate, this
            corporation"s financial support for universal capital punishment should be taken into account. Many
            experiments have shown that estrogen is very important for aggressive behavior in animals, and estrogen
            promotes serotonin"s actions. Some research shows that increased serotonin is associated with certain types
            of increased aggressiveness, and antiserotonin agents decrease aggresiveness (Ieni, et al., 1985; McMillen,
            et al., 1987) but the clearest research has to do with the crucial role of serotonin in learned
            helplessness. Learned helplessness is a biological condition that is created by inescapable stress. In this
            state, animals that would normally swim for hours will stop swimming after a few minutes and allow
            themselves to drown. They simply don"t have enough mental or physical energy to overcome challenges.
        </p>
        <p>
            In learned helplessness, the level of serotonin is high, and an excess of serotonin helps to create the
            state of learned helplessness.
        </p>
        <p>
            Serotonin activates glycolysis, forming lactic acid. Excess lactic acid tends to decrease efficient energy
            production by interfering with mitochondrial respiration.
        </p>
        <p>
            Heart failure, hypertension, muscle hyperalgesia (Babenko, et al., 2000), some panic reactions, and other
            maladaptive biological events associated with problems of energy metabolism, are promoted by excessive
            serotonin.

        <p>
            Autistic children and their relatives have high concentrations of serotonin in their serum and platelets.
            Members of a family tend to eat the same foods and to share other environmental conditions. Prenatal
            hypothyroidism and various kinds of imprinting, including hyperestrogenism, could account for this. Some
            studies have reported that thyroid supplements help autistic children, and anti-serotonin drugs have caused
            improvement in both children and adults.
        </p>
        <p>
            Serotonin tends to cause hypoglycemia, and hypoglycemia inhibits the conversion of thyroxine into the active
            T3 hormone. Hypoglycemia and hypothyroidism increase noradrenaline, and autistic people have been found to
            have more noradrenaline than normal. These changes, along with the general hypometabolism caused by excess
            serotonin, seem to justify the use of a thyroid supplement in autism and other serotonin-excess syndromes.
        </p>
        <p>
            Overdose with the serotonin reuptake inhibitors, or with 5-hydroxytryptophan, which has effects similar to
            serotonin, can cause the sometimes fatal "serotonin syndrome." Symptoms can include tremors, altered
            consciousness, poor coordination, cardiovascular disturbances, and seizures. Treatment with anti-serotonin
            drugs can alleviate the symptoms and usually can prevent death.
        </p>
        <p>
            The serotonin syndrome has been reported in users of St. John"s wort as an antidepressant. Since the other
            large neutral amino acids compete with tryptophan for entry into cells, the branched chain amino acids have
            some anti-serotonin activity, and this could be a justification for their use by athletes, since tryptophan
            and serotonin decrease glycogen stores and reduce endurance.
        </p>
        <p>
            The only amino acid that has ever been found to be carcinogenic is tryptophan. Its ability to mimic estrogen
            in promoting the release of prolactin is probably responsible.
        </p>
        <p>
            A large carbohydrate meal increases the ratio of tryptophan to the competing amino acids, and it has been
            proposed that this can shift the body"s balance toward increased serotonin. In an animal study,
            bromocriptine, which shifts the balance away from serotonin, reduced obesity and insulin and free fatty
            acids, and improved glucose tolerance.
        </p>
        <p>
            All of these observations are easiest to understand in terms of the suppression of cellular energy.
            Serotonin, like estrogen, lowers cellular ATP and interferes with oxidative metabolism.
        </p>
        <p>
            Serotonin, like histamine, has its proper physiological functions, but it is a mediator of stress that has
            to be systematically balanced by the systems that support high energy respiratory metabolism. The use of
            supplements of tryptophan, hydroxytryptophan, or of the serotonin promoting antidepressant drugs, seems to
            be biologically inappropriate.
        </p>
        <p>
            Many of the symptoms produced by excess serotonin are also the symptoms of hypothyroidism. Thyroid,
            progesterone, and high quality protein nutrition are central to protection against the serotonin syndromes.
            (Progesterone, like LSD, can inhibit the firing of serotonergic nerves, but an overdose, unlike LSD, never
            produces hallucinations.)
        </p>
        <p>
            One of the many actions of the "SSRI" (such as fluoxetine, Prozac), which aren"t related to their effect on
            serotonin, is to increase the concentration of allopregnanolone in the brain, imitating the action of
            increased progesterone. Following this discovery, Lilly got Prozac approved as a treatment for premenstrual
            syndrome. Since the production of allopregnanolone and progesterone depends on the availability of
            pregnenolone and cholesterol, a low cholesterol level would be one of the factors making this an
            inappropriate way to treat PMS.
        </p>
        <p>
            If we think biologically, starting with the role of serotonin as a damage-induced inflammatory mediator, we
            can speculate that an infinite number of irritating substances will be "serotonin reuptake inhibitors." The
            particular history of the "third generation antidepressants" is one that should disturb our tranquility.

        Medicine IV, Gastroenterology and Hepatology, University of Vienna, Austria. The increase of the brain levels of
        5-hydroxyindoleacetic acid (5-HIAA) in hepatic encephalopathy (HE) suggests an increased turnover of serotonin
        (5-HT). To study the role of tryptophan on the increased brain 5-HT metabolism in HE, we attempted to monitor
        brain levels of tryptophan in rats with thioacetamide-induced acute liver failure by intravenous infusion of
        branched-chain amino acids (BCAA). The effect of this treatment on 5-HT synthesis and metabolism was
        investigated in five brain areas. BCAA-infusions (1 and 2 gm/kg/24 h) increased the ratio BCAA/aromatic amino
        acids in plasma two- and fourfold, respectively, and lowered both plasma and brain levels of tryptophan. At the
        higher BCAA-dose all parameters suggesting an altered brain 5-HT metabolism (increased brain levels of 5-HT and
        5-HIAA, increased 5-HIAA/5-HT ratio) were almost completely normalized. These results provide further evidence
        for the role of tryptophan in the elevation of brain 5-HT metabolism and for a potential role of BCAA in the

        Laboratory of Neuroendocrinology, Rockefeller University, New York, NY 10021, USA. Atrophy and dysfunction of
        the human hippocampus is a feature of aging in some individuals, and this dysfunction predicts later dementia.
        There is reason to believe that adrenal glucocorticoids may contribute to these changes, since the elevations of
        glucocorticoids in Cushing's syndrome and during normal aging are associated with atrophy of the entire
        hippocampal formation in humans and are linked to deficits in short-term verbal memory. We have developed a
        model of stress-induced atrophy of the hippocampus of rats at the cellular level, and we have been investigating
        underlying mechanisms in search of agents that will block the atrophy. Repeated restraint stress in rats for 3
        weeks causes changes in the hippocampal formation that include suppression of 5-HT1A receptor binding and
        atrophy of dendrites of CA3 pyramidal neurons, as well as impairment of initial learning of a radial arm maze
        task. <strong>Because serotonin is released by stressors and may play a role in the actions of stress on nerve
            cells, we investigated the actions of agents that facilitate or inhibit serotonin reuptake.</strong>
        Tianeptine is known to enhance serotonin uptake, and we compared it with fluoxetine, an inhibitor of 5-HT
        reuptake, as well as with desipramine. Tianeptine treatment (10 mg/kg/day) prevented the stress-induced atrophy
        of dendrites of CA3 pycamidal neurons, whereas neither fluoxetine (10 mg/kg/day) nor desipramine (10 mg/kg/day)
        had any effect. Tianeptine treatment also prevented the stress-induced impairment of radial maze learning.
        Because <strong>corticosterone- and stress-induced atrophy of CA3 dendrites is also blocked by phenytoin, an
            inhibitor of excitatory amino acid release and actions, these results suggest that serotonin released by
            stress or corticosterone may interact pre- or post-synaptically with glutamate released by stress or
            corticosterone, and that the final common path may involve interactive effects between serotonin and
            glutamate receptors on the dendrites of CA3 neurons innervated by mossy fibers from the dentate gyrus. We
            discuss the implications of these findings for treating cognitive impairments and the risk for dementia in

        Benedict CR, Versteeg DH, de Kloet ER. The effect of therapeutic doses of digitalis in modifying neural activity
        has been the subject of considerable controversy. In earlier studies we reported <strong>an increase both in
            serotonergic activity in the posterior hypothalamus and pons-medulla and in cardiac sympathetic tone in the
            failing cardiomyopathic hamster.</strong> In this study we examine the effects of doses of digitoxin, known
        to be therapeutic for hamster heart failure, on monoamine neurotransmitter metabolism in the brain and heart
        during the cardiomyopathy. Both digitoxin and ASI-222, a polar amino-glycoside which does not cross the<strong>
        </strong>blood-brain barrier, given either acutely (6 mg/kg ip) or chronically (2 mg/kg/day ip for 10 days),
        normalized the failure-induced increase in serotonin turnover in the pons-medulla but had no effect on the
        changes in the posterior hypothalamus. Digitoxin therapy also reduced cardiac and adrenal sympathetic activity
        partially restoring cardiac catecholamine stores. In order to more clearly define the pathways involved we
        measured serotonin (microgram/g protein) in 18 brain nuclei after 10 days of digitoxin or vehicle treatment.
        <strong>Heart failure was associated with an increase in serotonin in five nuclei: the mammillary bodies,

        and ventromedialis nuclei; neither congestive heart failure nor digitoxin affected serotonin levels in other
        nuclei. We conclude that there is an increase in activity in specific brain serotonergic nuclei in congestive
        heart failure. Digitalis reduces cardiac sympathetic tone and restores the changes in two of these nuclei: the

        escape test into two groups: a "helpless" (LH) group which demonstrates a deficit in escape behavior, and a
        "nonlearned helpless" (NLH) group which shows no escape deficit and acquires the escape response as readily as
        naive control rats (NC) do." "The major finding concerned a significant increase in endogenous and
        K(+)-stimulated serotonin (5-HT) release in the hippocampal slices of LH rats. There were no apparent
        differences in acetylcholine, dopamine and noradrenaline release in the hippocampus of LH rats as compared to
        NLH and NC rats. These results add further support to previous studies in our laboratory which implicate
        presynaptic 5-HT mechanisms in the behavioral deficit caused by uncontrollable shock."Psychiatry Res 1994

        L, Jordan S Mental Health Clinic, Dallas Veterans Affairs Medical Center, TX. Learned helplessness, a behavioral
        depression caused by exposure to inescapable stress, is considered to be an animal model of human depressive
        disorder. Like human depression, learned helplessness has been associated with a defect in serotonergic
        function, but the nature of this relationship is not entirely clear. We have used in vivo microdialysis brain
        perfusion to measure serotonin (5-hydroxytryptamine, 5HT) in extracellular space of medial frontal cortex in
        conscious, freely moving rats. Basal 5HT levels in rats perfused before exposure to tail-shock stress did not
        themselves correlate with subsequent learned helplessness behavior. However, 5HT release after stress showed a
        significant increase with helpless behavior. <strong>These data support the hypothesis that a cortical
            serotonergic excess is causally related to the development of learned helplessness.</strong>Pharmacol
        Biochem Behav 1994 Jul;48(3):671-6. <strong>Does learned helplessness induction by haloperidol involve serotonin
            mediation?</strong> Petty F, Kramer G, Moeller M Veterans Affairs Medical Center, Dallas 75216. Learned
        helplessness (LH) is a behavioral depression following inescapable stress. Helpless behavior was induced in
        naive rats by the dopamine D2 receptor blocker haloperidol (HDL) in a dose-dependent manner, with the greatest
        effects seen at 20 mg/kg (IP). Rats were tested 24 h after injection. Haloperidol (IP) increased release of
        serotonin (5-HT) in medial prefrontal cortex (MPC) as measured by in vivo microdialysis. Perfusion of HDL
        through the probe in MPC caused increased cortical 5-HT release, as did perfusion of both dopamine and the
        dopamine agonist apomorphine. Our previous work found that increased 5-HT release in MPC correlates with the
        development of LH. The present work suggests that increased DA release in MPC, known to occur with both
        inescapable stress and with HDL, may play a necessary but not sufficient role in the development of LH. Also,
        this suggests that increased DA activity in MPC leads to increased 5-HT release in MPC and to subsequent
        behavioral depression.Stroke 1991 Nov;22(11):1448-51. <strong>Platelet secretory products may contribute to
            neuronal injury.</strong> Joseph R, Tsering C, Grunfeld S, Welch KM Department of Neurology, Henry Ford
        Hospital and Health Sciences Center, Detroit, MI 48202. BACKGROUND: We do not fully understand the mechanisms
        for neuronal damage following cerebral arterial occlusion by a thrombus that consists mainly of platelets. The
        view that certain endogenous substances, such as glutamate, may also contribute to neuronal injury is now
        reasonably well established. Blood platelets are known to contain and secrete a number of substances that have
        been associated with neuronal dysfunction. Therefore, we hypothesize that a high concentration (approximately
        several thousand-fold higher than in plasma, in our estimation) of locally released platelet secretory products
        derived from the causative thrombus may contribute to neuronal injury and promote reactive gliosis. SUMMARY OF
        COMMENT: We have recently been able to report some direct support for this concept. When organotypic spinal cord
        cultures were exposed to platelet and platelet products, a significant reduction in the number and the size of
        the surviving neurons occurred in comparison with those in controls. We further observed that serotonin, a major
        platelet product, has neurotoxic properties. There may be other platelet components with similar effect.<strong>
            CONCLUSIONS: The hypothesis of platelet-mediated neurotoxicity gains some support from these recent in vitro
            findings. The concept could provide a new area of research in stroke, both at the clinical and basic
            levels.</strong>J. Clin Psychopharmacol 1991 Aug; 11(4):277-9.<strong>

        JA. Serotonin released from platelets may initiate coronary vasospasm in patients with variant angina. If this
        hypothesis is correct, serotonin antagonists without constrictor activity may be useful in this form of angina.
        We have investigated drugs classified as serotonin antagonists on dog circumflex coronary artery ring segments
        in vitro. Ergotamine, dihydroergotamine,<strong>
            bromocriptine, lisuride, ergometrine, ketanserin, trazodone, cyproheptadine and pizotifen caused
            non-competitive antagonism of serotonin concentration-response curves</strong>. In addition, ketanserin,
        trazodone, bromocriptine and pizotifen inhibited noradrenaline responses in concentrations similar to those
        required for serotonin antagonism. All drugs with the exception of ketanserin, cyproheptadine and pizotifen
        showed some degree of intrinsic constrictor activity. Methysergide antagonized responses to serotonin
        competitively but also constricted the coronary artery. The lack of a silent competitive serotonin antagonist
        precludes a definite characterization of coronary serotonin receptors at this time. However, the profile of
        activity observed for the antagonist drugs in the coronary artery differs from that seen in other vascular
        tissues. Of the drugs tested, ketanserin may be the most useful in variant angina since it is a potent 5HT
        antagonist, lacks agonist activity and has alpha-adrenoceptor blocking activity.Eur J Pharmacol 1985 May

        behavior, locomotor activity and brain monoamines were examined. P-chlorophenylalanine (200 and 400 mg/kg) and
        5-hydroxytryptophan (100 mg/kg) inhibited fighting behavior of postpartum mice toward unfamiliar male intruder
        mice. These drug-treated postpartum females showed increased latencies to attack male intruders and also reduced
        frequencies of attack. In addition, <strong>postpartum mice treated with the serotonin receptor antagonists,

        <strong>In support of this conclusion was the observed potentiation of antiaggressive effects by blocking 5HT
            receptors</strong> wit small doses of methiothepin or methysergide, which would exacerbate the decreased
        release of 5HT caused by gepirone. These results are in harmony with reports that decreased serotonergic

        <p><strong>Serotonin: Effects in disease, aging and inflammation</strong></p>
        <p>
            Interpreting medical publications requires some skills that aren't needed for understanding more strictly
            scientific reports, because medical writing often takes into account the fact that physicians spend most of
            their time interacting with the public, rather than studying. The public's understanding of medicine is
            shaped by "public relations," by the introduction of words and concepts that frame the argument. (The
            linguist George Lakoff summarized the essence of public relations by observing that people reject facts that
            are outside their view of reality, their mental framework.) Television and public schools now frame the
            worldview of the affluent cultures, according to the needs of the ruling powers. Long before specific
            prescription drugs could be advertised directly to consumers, the medical and pharmaceutical industries were
            creating a favorable frame for their products.Many years ago, public relations experts used expensive
            opinion polls to judge the effectiveness of their efforts, but now there is a convenient way to see how the
            general public is thinking: Wikipedia, the internet encyclopedia. The success of corporate advertising can
            be seen in their recent article on serotonin, which says "It is a well-known contributor to feelings of
            well-being; therefore it is also known as a 'happiness hormone' despite not being a hormone."The culture
            that has happy and unhappy hormones was a culture in which each hormone had a receptor, a substance in a
            cell which, when its ligand was bound to it, made the cell do something. Although that culture still has
            influence in the 21st century, discoveries made between 1940 and 1970 showed that those mechanical ideas of
            receptors didn't reflect biological reality. Albert Szent-Gyorgi and the Pullmans showed that the electronic
            qualities of molecules determined their functions, and Szent-Gyorgyi showed that the state of the cell,
            tissue, and organism governed the effect of hormones and drugs. In the 1960s, substances with very different
            biological effects, such as acetylcholine and adrenaline, were shown to be selectively bound to the same
            cellular site in some cells. It was primarily the drug industry that created and sustained the specific
            receptor doctrine. That doctrine suited the recognition of their public relations- marketing experts, that
            successful advertising had to be directed at the sixth-grade educational level. The ideas of bioelectronics
            and context-sensitive molecules, like morphogenetic fields, were just too complicated to sell well.Although
            metaphorical thinking can be creative and productive, metaphors mustn't be taken literally. The
            identification of multiple types of receptor for a given natural substance involves the use of different
            substances as metaphors or similes for the natural substance. That type of pharmacology is slowly being
            replaced by an attempt to understand state-dependent sensitivities. The energetic state of a cell, and of
            the whole organism, determines the meaning of events and conditions, such as the presence of the "regulatory
            substances."The receptor culture can be tentatively disregarded when thinking about the history of
            serotonin. In the 1930s Vittorio Erspamer identified an amine in the intestine, that caused the intestine to
            contract. Then a group in England extracted an amine from serum that caused blood vessels to contract, and
            identified its chemical nature. Later, Erspamer showed that the intestinal amine and the vascular amine were
            chemically the same. The English group who had identified the substance by extracting tons of beef blood,
            wanted to find sensitive ways to assay it for further studies, and in 1951 they gave a sample to a
            pharmacologist, John Gaddum, who tested its effects on tissues including blood vessels and rat
            uteruses.Gaddum tested the serotonin in combination with a variety of other drugs, including ergot
            derivatives, that he knew acted on smooth muscles, and very soon observed that LSD blocked the effects of
            serotonin. Since he knew that LSD produced mental effects (Sandoz had distributed samples of it to
            researchers in 1947), he reasoned that the brain might also contain serotonin, and by 1952 was able to
            demonstrate that it does contain small amounts of it. A couple of years later he suggested "that the mental
            effects of lysergic acid diethylamide are due to interference with the normal action of this HT [5-
            hydroxytryptamine, serotonin]." At the Rockefeller Institute in New York, Woolley and Shaw also saw the
            antagonistic effects on smooth muscle, and drew similar conclusions about the brain. Erspamer (Renic. sc.
            farmital. 1, 1, 1954) showed that LSD was a highly effective antagonist against the antidiuresis caused by
            serotonin (enteramine).Around the same time, in the early 1950s, several people recognized that the symptoms
            produced by administering an excess of serotonin were similar to those experienced by people with intestinal
            tumors called argentaffinomas or carcinoid tumors, which are usually in the small intestine or appendix. The
            normal intestine contains about 95% of the serotonin in the body (and the brain normally contains only about
            1%), and in the normal person only about 1% of the dietary tryptophan is converted to serotonin. But in an
            advanced case of carcinoid, 60% of the tryptophan can be turned into serotonin. Especially if the tumor has
            invaded the liver, the serotonin won't be destroyed by the liver in the usual way, and will circulate in the
            bloodstream at high levels, producing symptoms of flushing, sweating (sometimes dark-colored), diarrhea
            (serotonin stimulates small intestine smooth muscle, but inhibits the large [Bennett &amp; Whitney, 1966]),
            nausea, anxiety, reduced urination, muscle and joint pains, and, in late stages, very often cardiovascular
            disease (especially inflammation, fibroma and calcification of the valves in the right side of the heart)
            and aggressive behavior (Russo, et al., 2004) and psychosis.Testing Gaddum's idea of antagonism between LSD
            and serotonin in humans, Montanari and Tonini found that intramuscular injections of serotonin antagonized
            the psychological effects of LSD. Other drugs, especially other ergot derivatives, were more successful than
            LSD in blocking the effects of serotonin (Dubach and Gsell, 1962). There have been suggestions that
            pregnancy hormones could control serotonin excess (McCullough and Myers, 1965). Since estrogen promotes
            serotonin, progesterone is likely to be the protective factor (Donner &amp; Handa, 2009; Hiroi, et al.,
            2006; Berman, et al., 2006; Bethea, et al., 2000).More recently (Spigset, et al., 2004), it was found that
            LSD binding to a presumed serotonin receptor was low in carcinoid patients, supporting the idea of
            antagonism between the substances, but in the older studies symptoms, rather than competition for binding to
            certain proteins, were the focus of attention. The effects produced by injections and oral doses of
            synthetic serotonin, and of substances that block the synthesis of serotonin, were studied in both animals
            and humans. When a symptom such as clotting, flushing, or diarrhea is produced by serotonin itself, or
            prevented by a blocker of serotonin synthesis, "receptors" aren't an issue.Aldous Huxley was one of the
            first people to think about the general biological meaning of drugs such as LSD. Referring to the ideas of
            Henri Bergson and William Blake, he suggested that the brain usually acts as a filter, or "reducing valve,"
            to make us disregard most of the information we are receiving through our senses, and that the psychedelic
            drugs temporarily remove the filter, or open the sensory reducing valve. Bergson had suggested that the
            filter was a practical measure needed to allow us to focus on practical survival needs; Blake had suggested
            that the doors of perception were kept closed for cultural reasons.Some recent reviews have discussed the
            evidence supporting the serotonin system as primarily inhibitory and protective (Anne Frederickson, 1998,
            Neil Goodman, 2002). Goodman describes the serotonergic system as one of our "diffuse neuroregulatory
            systems," and suggests that drugs such as LSD weaken its inhibitory, filtering effect. (Jacobs, 1983, 1987:
            by changes in the effects of serotonin in the brain, produced by things that affect its synthesis, release,
            catabolism, or receptor action.) LSD depresses the rate of firing of serotonergic nerves in the raphe nuclei
            (Trulson and Jacobs, 1979) causing arousal similar to stimulation of the reticular formation, as if by
            facilitating sensory input into the reticular formation (Bowman and Rand, 1980).In European culture, some
            people--e.g., Plato, Descarte, Locke, Eccles, probably even B.F. Skinner--have believed that mind and body
            are essentially different things (analogous to computer hardware and its programs), while another
            tradition--Blake, Lamarck, Darwin, C.L. Morgan, Pavlov, Reich, C.R. Cloninger, for example--has emphasized
            the continuity of consciousness and character with the body.Understanding the authoritarian personality has
            been an important issue in the 20th century. Wilhelm Reich used some old ideas about the nervous system that
            were current near the beginning of the century, and Cloninger (1995) and others (Netter, et al., 1996,
            Ruegg, et al., 1997, Gerra, 2000), toward the end of the century, were able to incorporate the newer
            information about the serotonergic-dopaminergic antagonisms. In this newer view, high serotonin production
            causes behavioral inhibition and harm avoidance, which are traits of the authoritarian personality, while
            anti-authorians tend to have "novelty seeking" personalities, with high dopamine and low serotonin
            functions.In the 1960s, experimenters put electrodes into a chicken's optic nerve, and when the chicken saw
            a checkerboard pattern, they could measure a patterned electrical activity in the nerve. Without the light
            stimulating the retina, the nerve was quiet. But when they gave the chicken LSD or similar chemicals, they
            recorded patterned electrical activity in the nerve, in the absence of external stimulation. Around the same
            time, other experimenters showed that retinal fatigue quickly desensitized the retina, preventing the
            transmission of impulses to the brain, except when the light pattern corresponded to something familiar,
            showing that impulses from the brain are always involved in renewing, in patterned ways, the sensitivity of
            the retina.The latter experiment shows that everyone's perception involves an outward-directed activity of
            the brain, and the experiments using the chemical stimulants suggested that the intensity of the outward-
            directed action can vary.The inhibitory serotonergic "harm avoidance" system, and the opposing excitatory
            activating "novelty seeking" systems are constantly being influenced by many factors, including nutrition,
            hormones, environmental challenges and opportunities, social interactions, seasons, and the rhythm of night
            and day alternation.Several kinds of research are now showing that the effects of the environment on the
            serotonergic system and its antagonists can influence every aspect of health, not just the personality.For
            example, there have been suggestions that early life isolation of an animal can affect its serotonergic
            activity and increase its anxiety, aggression, or susceptibility to stress (Malick and Barnett, 1976,
            Malick, 1979, dos Santos, et al, 2010), and these effects are associated with increased risk of becoming
            depressed, and developing organic problems. Animals kept in darkness (or with blurring lenses) become
            nearsighted, as the eyeball grows longer under the influence of increased serotonin, and the eyes are
            protected against myopia by serotonin antagonists (George, et al., 2005). The incidence of myopia is
            increasing, at least in countries with industrialized economies, and is more common in females.Migraine
            headaches are also increasing in incidence. By the end of the 1950s, it was widely accepted that migraine
            headaches and associated symptoms including nausea and visual disturbances were caused by an excess of
            serotonin, and antiserotonin drugs of various types were being used for treatment. In one of the early
            studies of the use of LSD in psychotherapy, some of the patients noticed that their chronic headaches had
            stopped. Cluster headaches have also responded well to LSD and similar drugs (Sewell, et al., 2006).Women
            have migraines more often than men do, and they tend to occur in association with ovulation or menstruation.
            Estrogen inhibits monoamino oxidase, MAO, especially the A form that is most active in detoxifying
            serotonin, and it increases the enzymes that control the rate of serotonin synthesis. During serotonin
            excess, the veins and capillaries of the pia mater are engorged with blood, while circulation to the brain
            generally is depressed. Visual symptoms are probably produced by contriction of arterioles, while the pain
            is associated with engorged veins. Progesterone activates the MAO-A, and has other antiserotonin effects on
            blood vessels and nerves.Recently (Shansky, et al., 2010; Figueiredo, et al., 2007), females have been found
            to be more susceptible to stress, and to have reduced uptake of serotonin (prolonging its effects), which
            increases glucocorticoids and ACTH. Kendler, et al. (2005) have found that people with reduced serotonin
            uptake are more susceptible to stress-induced depression.The increase of inhibitory serotonin with stress
            and depression is probably biologically related to the role of serotonin in hibernation, which is an extreme
            example of "harm avoidance" by withdrawal. A diet high in polyunsaturated fat increases the tendency to go
            into hibernation, probably by increasing the brain's uptake of tryptophan. When this is combined with an
            increasingly cold environment, the form of MAO that removes serotonin decreases its activity, while the form
            that removes norepinephrine increases its activity. The metabolite of serotonin, 5-HIAA, decreases, as the
            effect of serotonin increases.In experiments to investigate the mechanism of hibernation, animals were
            injected with serotonin, at different environmental temperatures. In a cool environment, the serotonin
            caused their temperature to fall, by decreasing their heat production, and increasing their loss of heat (by
            causing vasodilation in the skin, "flushing"). In a hot environment, serotonin can cause the animal's
            temperature to rise.Serotonin can reduce the production of energy by inhibiting mitochondrial respiratory
            enzymes (Medvedev, 1990, 1991), and by reduction of oxygen delivery to tissues by vasoconstriction. It also
            appears to interfere with the use of glucose (de Leiva, et al., 1978, Moore, et al., 2004).The brains of
            people with Alzheimer's disease have a decreased ability to metabolize glucose, and high cortisol
            contributes to the altered glucose metabolism, and to the destruction of nerve cells. People with
            Cloninger's "harm avoidance" personality trait, which is closely associated with serotonin (Hansenne, et
            al., 1999), are more likely to develop dementia (Clément, et al., 2010). These observations are consistent
            with the stress-susceptibility of people with high serotonin exposure, and to the effects of cortisol on
            nerves and glucose-derived energy production.Researchers in Brasil have suggested that the serotonergic
            system facilitates conditioned fear, while inhibiting the fight or flight reaction, and that this can
            protectively limit the stress response (Graeff, et al., 1996). "5HT systems reduce the impact of impending
            or actual aversive events. Anticipation of an aversive event is associated with anxiety and this motivates
            avoidance behaviour" (Deakin, 1990). In a stressful situation, the serotonergic nerves can prevent ulcers.
            In other contexts, though, increased serotonin can cause ulcers.The protective, defensive reactions
            involving serotonin's blocking of certain types of reaction to ordinary stresses, are similar to the effects
            of serotonin in hibernation and in Alzheimer's disease (Mamelak, 1997; Heininger, 2000; Perry, et al.,
            2002). In those extreme conditions, serotonin reduces energy expenditure, eliminating all brain functions
            except those needed for simple survival. These parallels suggest that improving energy production, for
            example by providing ketones as an alternative energy source, while reducing the stress hormones, might be
            able to replace the defensive reactions with restorative adaptive nerve processes, preventing or reversing
            Alzheimer's disease.One of the factors promoting excess cortisol production is intestinal irritation,
            causing absorption of endotoxin and serotonin. Fermentable fibers (including pectins and
            fructooligosaccharides) support the formation of bacterial toxins, and can cause animals to become anxious
            and aggressive. Fed to horses, some types of fiber increase the amount of serotonin circulating in the
            blood. Grains, beans, and other seeds contain fermentable fibers that can promote intestinal irritation.The
            liver has several ways to detoxify endotoxin and serotonin, but these can fail as a result of poor nutrition
            and hypothyroidism.The lung can bind and destroy any excess serotonin that reaches it. A lack of carbon
            dioxide makes platelets release their stored serotonin, and it probably has the same effect in the lung
            endothelial cells. Without being able to bind the serotonin, the enzyme (indoleamine 2,3-dioxygenase) would
            be unable to destroy it.An excess of tryptophan in the diet, especially with deficiencies of other
            nutrients, can combine with inflammation to increase serotonin. Polyunsaturated fatty acids promote the
            absorption of tryptophan by the brain, and its conversion to serotonin. (A "deficiency" of polyunsaturated
            fat decreases the expression of the enzyme that synthesizes serotonin [McNamara, et al., 2009).Some fruits,
            including bananas, pineapples, and tomatoes, contain enough serotonin to produce physiological effects in
            susceptible people.Besides avoiding foods containing fermentable fibers and starches that resist quick
            digestion, eating fibrous foods that contain antibacterial chemicals, such as bamboo shoots or raw carrots,
            helps to reduce endotoxin and serotonin. Activated charcoal can absorb many toxins, including bacterial
            endotoxin, so it is likely to reduce serotonin absorption from the intestine. Since it can also bind or
            destroy vitamins, it should be used only intermittently. Frolkis, et al. (1989, 1984) found that it extended
            median and average lifespan of rats, beginning in old age (28 months) by 43% and 34%, respectively, when
            given in large quantities (equivalent to about a cup per day for humans) for ten days of each month.The
            amino acid theanine, found in tea, has been reported to decrease the amount of serotonin in the brain,
            probably by decreasing its synthesis and increasing its degradation.&nbsp;This seems to be the opposite of
            the processes in hibernation. Progesterone, thyroid, and niacinamide (not nicotinic acid or inositol
            hexanicotinate) are other safe substances that help to reduce serotonin formation, and/or accelerate its
            elimination. (Niacinamide seems to increase serotonin uptake.)To provide usable energy to the over-stressed
            brain (and heart), R.L. Veech has advocated the use of ketones, but the pure chemicals are expensive to
            make. An easily available and inexpensive source of ketones (in the form of ketoacids, which can be
            converted to amino acids if they aren't needed for energy) is the juice extracted (with a centrifugal
            juicer) from raw potatoes, which also contains proteins and other nutrients. The juice can be scrambled like
            eggs, and is usually tolerated even by very debilitated people.Hypothyroidism is a very common cause of
            increased serotonin (e.g., Henley, et al., 1998), and if the thyroid hormone is supplemented until symptoms
            are resolved, it's likely that the serotonin will have been normalized.<h3>REFERENCES</h3>Vet Rec. 2010 Jan

                Sugar issues</strong>
        </p>
        <p></p>Since the first doctor noticed, hundreds of years ago, that the urine of a diabetic patient tasted sweet,
        it has been common to call the condition the sugar disease, or sugar diabetes, and since nothing was known about
        physiological chemistry, it was commonly believed that eating too much sugar had to be the cause, since the
        ability of the body to convert the protein in tissues into sugar wasn"t discovered until 1848, by Claude Bernard
        (who realized that diabetics lost more sugar than they took in). Even though patients continued to pass sugar in
        their urine until they died, despite the elimination of sugar from their diet, medical policy required that they
        be restrained to keep them from eating sugar. That prescientific medical belief, that eating sugar causes
        diabetes, is still held by a very large number, probably the majority, of physicians. Originally, diabetes was
        understood to be a wasting disease, but as it became common for doctors to measure glucose, obese people were
        often found to have hyperglycemia, so the name diabetes has been extended to them, as type 2 diabetes. High
        blood sugar is often seen along with high blood pressure and obesity in Cushing's syndrome, with excess
        cortisol, and these features are also used to define the newer metabolic syndrome. Following the old reasoning
        about the sugar disease, the newer kind of obese diabetes is commonly blamed on eating too much sugar. Obesity,
        especially a fat waist, and all its associated health problems, are said by some doctors to be the result of
        eating too much sugar, especially fructose. (Starch is the only common carbohydrate that contains no fructose.)
        Obesity is associated not only with diabetes or insulin resistance, but also with atheroslcerosis and heart
        disease, high blood pressure, generalized inflammation, arthritis, depression, risk of dementia, and cancer.
        There is general agreement about the problems commonly associated with obesity, but not about the causes or the
        way to prevent or cure obesity and the associated conditions. In an earlier newsletter, I wrote about P. A.
        Piorry in Paris, in 1864, and Dr. William Budd in England, in 1867, who treated diabetes by adding a large
        amount of ordinary sugar, sucrose, to the patient's diet. Glucose was known to be the sugar appearing in the
        diabetics' urine, but sucrose consists of half glucose, and half fructose. In 1874, E. Kulz in Germany reported
        that diabetics could assimilate fructose better than glucose. In the next decades there were several more
        reports on the benefits of feeding fructose, including the reduction of glucose in the urine. With the discovery
        of insulin in 1922, fructose therapy was practically forgotten, until the 1950s when new manufacturing
        techniques began to make it economical to use. Its use in diabetic diets became so popular that it became
        available in health food stores, and was also used in hospitals for intravenous feeding. However, while fructose
        was becoming popular, the cholesterol theory of heart disease was being promoted. This was the theory that
        eating foods containing saturated fat and cholesterol caused heart disease. (My newsletter, Cholesterol,
        longevity, intelligence, and health, discussed the development of that theory.) A Swedish physician and
        researcher, Uffe Ravnskov, has reviewed the medical arguments for the theory that lipids in the blood are the
        cause of atherosclerosis and heart disease, and shows that there has never been evidence of causality, something
        which some people, such as Broda Barnes, understood from the beginning. In the 1950s, an English professor, John
        Yudkin, didn't accept the idea that eating saturated fat was the cause of high blood levels of triglycerides and
        cholesterol, but he didn"t question the theory that lipids in the blood caused the circulatory disease. He
        argued that it was sugar, especially the fructose component of sucrose, rather than dietary fat, that caused the
        high blood lipids seen in the affluent countries, and consequently the diseases. He was sure it was a specific
        chemical effect of the fructose, because he argued that the nutrients that were removed in refining white flour
        and white sugar were insignificant, in the whole diet. Following the publication of Yudkin's books, and
        coinciding with increasing promotion of the health benefits of unsaturated vegetable oils, many people were
        converted to Yudkin's version of the lipid theory of heart disease, i.e., that the "bad lipids" in the blood are
        the result of eating sugar. This has grown into essentially a cult, in which sugar is believed to act like an
        intoxicant, forcing people to eat until they become obese, and develop the "metabolic syndrome," and "diabetes,"
        and the many problems that derive from that. The publicity campaign against "saturated fat" as an ally of
        cholesterol derived its support from the commercial promotion of the polyunsaturated seed oils as food for
        humans. Although the early investigators of vitamin E knew that the polyunsaturated oils could cause sterility,
        and others later found that their use in commercial animal foods could cause brain degeneration, there were a
        few biologists (mostly associated with George Burr) who believed that this type of fatty acid is an essential
        nutrient. George and Mildred Burr had created what they claimed to be a disease in rats caused by the absence of
        linoleic or linolenic acid in their food. Although well known researchers had previously published evidence that
        animals on a fat free diet were healthy--even healthier than on a normal diet--Burr and his wife published their
        contradictory claim without bothering to discuss the conflicting evidence. I haven't seen any instance in which
        Burr or his followers ever mentioned the conflicting evidence. Although other biologists didn't accept Burr's
        claims, and several researchers subsequently published contrary results, he later became famous when the seed
        oil industry wanted scientific-seeming reasons for selling their product as an "essential" food. The fact that
        eating the polyunsaturated fats could cause the blood cholesterol level to decrease slightly was advertised as a
        health benefit. Later, when human trials showed that more people on the "heart healthy" diet died of heart
        disease and cancer, more conventional means of advertising were used instead of human tests. Burr's experimental
        diet consisted of purified casein (milk protein) and purified sucrose, supplemented with a vitamin concentrate
        and some minerals. Several of the B vitamins weren't known at the time, and the mineral mixture lacked zinc,
        copper, manganese, molybdenum, and selenium. More of the essential nutrients were unknown in his time than in
        Yudkin's, so his failure to consider the possibility of other nutritional deficiencies affecting health is more
        understandable. In 1933, Burr observed that his fat-deficient rats consumed oxygen at an extremely high rate,
        and even then, the thought didn't occur to him that other nutritional deficiencies might have been involved in
        the condition he described. Ordinarily, the need for vitamins and minerals corresponds to the rate at which
        calories are being burned, the metabolic rate. Burr recalled that the rats on the fat free diet drank more
        water, and he reasoned that the absence of linoleic or linolenic acid in their skin was allowing water vapor to
        escape at a high rate. He didn't explain why the saturated fats the rats were synthesizing from sugar didn't
        serve at least as well as a "vapor barrier"; they are more effective at water-proofing than unsaturated fats,
        because of their greater hydrophobicity. The condensed and cross-linked keratin protein in skin cells is the
        main reason for the skin's relatively low permeability. When an animal is burning calories at a higher rate, its
        sweat glands are more actively maintaining a normal body temperature, cooling by evaporation; the amount of
        water evaporated is an approximate measure of metabolic rate, and of thyroid function. In 1936, a man in Burr's
        lab, William Brown, agreed to eat a similar diet for six months, to see whether the "essential fatty acid
        deficiency" affected humans as it did rats. The diet was very similar to the rats', with a large part of the
        daily 2500 calories being provided at hourly intervals during the day by sugar syrup (flavored with citric acid
        and anise oil), protein from 4 quarts of special fat-free skimmed milk, a quart of which was made into cottage
        cheese, the juice of half an orange, and a "biscuit" made with potato starch, baking powder, mineral oil, and
        salt, with iron, viosterol (vitamin D), and carotene supplemented. Brown had suffered from weekly migraine
        headaches since childhood, and his blood pressure was a little high when he began the diet. After six weeks on
        the diet, his migraines stopped, and never returned. His plasma inorganic phosphorus declined slightly during
        the experiment (3.43 mg./100 cc. of plasma and 2.64 on the diet, and after six months on a normal diet 4.2
        mg.%), and his total serum proteins increased from 6.98 gm.% to 8.06 gm.% on the experimental diet. His
        leucocyte count was lower on the high sugar diet, but he didn't experience colds or other sickness. On a normal
        diet, his systolic blood pressure varied from 140 to 150 mm. of mercury, the diastolic, 95 to 100. After a few
        months on the sugar and milk diet, his blood pressure had lowered to about 130 over 85 to 88. Several months
        after he returned to a normal diet, his blood pressure rose to the previous level. On a normal diet, his weight
        was 152 pounds, and his metabolic rate was from 9% to 12% below normal, but after six months on the diet it had
        increased to 2% below normal. After three months on the sugar and milk diet, his weight leveled off at 138
        pounds. After being on the diet, when he ate 2000 calories of sugar and milk within two hours, his respiratory
        quotient would exceed 1.0, but on his normal diet his maximum respiratory quotient following those foods was
        less than 1.0. The effect of diabetes is to keep the respiratory quotient low, since a respiratory quotient of
        one corresponds to the oxidation of pure carbohydrate, and extreme diabetics oxidize fat in preference to
        carbohydrate, and may have a quotient just a little above 0.7. The results of Brown's and Burr's experiments
        could be interpreted to mean that the polyunsaturated fats not only lower the metabolic rate, but especially
        interfere with the metabolism of sugars. In other words, they suggest that the normal diet is diabetogenic.
        During the six months of the experiment, the unsaturation of Brown's serum lipids decreased. The authors
        reported that "There was no essential change in the serum cholesterol as a result of the change in diet."
        However, in November and December, two months before the experiment began, it had been 252 mg.% in two
        measurements. At the beginning of the test, it was 298, two weeks later, 228, and four months later, 206 mg%.
        The total quantity of lipids in his blood didn't seem to change much, since the triglycerides increased as the
        cholesterol decreased. By the time of Brown's experiment, other researchers had demonstrated that the
        cholesterol level was increased in hypothyroidism, and decreased as thyroid function, and oxygen consumption,
        increased. If Burr's team had been reading the medical literature, they would have understood the relation
        between Brown's increased metabolic rate and decreased cholesterol level. But they did record the facts, which
        is valuable. The authors wrote that "The most interesting subjective effect of the 'fat-free' regimen was the
        definite disappearance of a feeling of fatigue at the end of the day's work." A lowered metabolic rate and
        energy production is a common feature of aging and most degenerative diseases. From the beginning of an animal's
        life, sugars are the primary source of energy, and with maturation and aging there is a shift toward replacing
        sugar oxidation with fat oxidation. Old people are able to metabolize fat at the same rate as younger people,
        but their overall metabolic rate is lower, because they are unable to oxidize sugar at the same high rate as
        young people. Fat people have a similar selectively reduced ability to oxidize sugar. Stress and starvation lead
        to a relative reliance on the fats stored in the tissues, and the mobilization of these as circulating free
        fatty acids contributes to a slowing of metabolism and a shift away from the use of glucose for energy. This is
        adaptive in the short term, since relatively little glucose is stored in the tissues (as glycogen), and the
        proteins making up the body would be rapidly consumed for energy, if it were not for the reduced energy demands
        resulting from the effects of the free fatty acids. One of the points at which fatty acids suppress the use of
        glucose is at the point at which it is converted into fructose, in the process of glycolysis. When fructose is
        available, it can by-pass this barrier to the use of glucose, and continue to provide pyruvic acid for
        continuing oxidative metabolism, and if the mitochondria themselves aren't providing sufficient energy, it can
        leave the cell as lactate, allowing continuing glycolytic energy production. In the brain, this can sustain life
        in an emergency. Many people lately have been told, as part of a campaign to explain the high incidence of fatty
        liver degeneration in the US, supposedly resulting from eating too much sugar, that fructose can be metabolized
        only by the liver. The liver does have the highest capacity for metabolizing fructose, but the other organs do
        metabolize it. If fructose can by-pass the fatty acids' inhibition of glucose metabolism, to be oxidized when
        glucose can't, and if the metabolism of diabetes involves the oxidation of fatty acids instead of glucose, then
        we would expect there to be less than the normal amount of fructose in the serum of diabetics, although their
        defining trait is the presence of an increased amount of glucose. According to Osuagwu and Madumere (2008), that
        is the case. If a fructose deficiency exists in diabetes, then it is appropriate to supplement it in the diet.
        Besides being one of the forms of sugar involved in ordinary energy production, interchangeable with glucose,
        fructose has some special functions, that aren't as well performed by glucose. It is the main sugar involved in
        reproduction, in the seminal fluid and intrauterine fluid, and in the developing fetus. After these crucial
        stages of life are past, glucose becomes the primary molecular source of energy, except when the system is under
        stress. It has been suggested (Jauniaux, et al., 2005) that the predominance of fructose rather than glucose in
        the embryo's environment helps to maintain ATP and the oxidative state (cellular redox potential) during
        development in the low-oxygen environment. The placenta turns glucose from the mother's blood into fructose, and
        the fructose in the mother's blood can pass through into the fetus, and although glucose can move back from the
        fetus into the mother's blood, fructose is unable to move in that direction, so a high concentration is
        maintained in the fluids around the fetus. The control of the redox potential is sometimes called the "redox
        signalling system," since it coherently affects all processes and conditions in the cell, including pH and
        hydrophobicity. For example, when a cell prepares to divide, the balance shifts strongly away from the oxidative
        condition, with increases in the ratios of NADH to NAD+, of GSH to GSSG, and of lactate to pyruvate. These same
        shifts occur during most kinds of stress. In natural stress, decreased availability of oxygen or nutrients is
        often the key problem, and many poisons can produce similar interference with energy production, for example
        cyanide or carbon monoxide, which block the use of oxygen, or ethanol, which inhibits the oxidation of sugars,
        fats, and amino acids (Shelmet, et al., 1988). When oxygen isn't constantly removing electrons from cells (being
        chemically reduced by them) those electrons will react elsewhere, creating free radicals (including activated
        oxygen) and reduced iron, that will create inappropriate chemical reactions (Niknahad, et al., 1995;
        MacAllister, et al., 2011). Stresses and poisons of many different types, interfering with the normal flow of
        electrons to oxygen, produce large amounts of free radicals, which can spread structural and chemical damage,
        involving all systems of the cell. Ethyl alcohol is a common potentially toxic substance that can have this
        effect, causing oxidative damage by allowing an excess of electrons to accumulate in the cell, shifting the
        cells' balance away from the stable oxidized state. Fructose has been known for many years to accelerate the
        oxidation of ethanol (by about 80%). Oxygen consumption in the presence of ethanol is increased by fructose more
        than by glucose (Thieden and Lundquist, 1967). Besides removing the alcohol from the body more quickly, it
        prevents the oxidative damage, by maintaining or restoring the cell's redox balance, the relatively oxidized
        state of the NADH/NAD+, lactate/pyruvate, and GSH/GSSH systems. Although glucose has this stabilizing,
        pro-oxidative function in many situations, this is a general feature of fructose, sometimes allowing it to have
        the opposite effect of glucose on the cell's redox state. It seems to be largely this generalized shift of the
        cell's redox state towards oxidation that is behind the ability of a small amount of fructose to catalyze the
        more rapid oxidation of a large amount of glucose. Besides protecting against the reductive stresses, fructose
        can also protect against the oxidative stress of increased hydrogen peroxide (Spasojevic, et al., 2009). Its
        metabolite, fructose 1,6-bisphosphate, is even more effective as an antioxidant. Keeping the metabolic rate high
        has many benefits, including the rapid renewal of cells and their components, such as cholesterol and other
        lipids, and proteins, which are always susceptible to damage from oxidants, but the high metabolic rate also
        tends to keep the redox system in the proper balance, reducing the rate of oxidative damage. Endotoxin absorbed
        from the intestine is one of the ubiquitous stresses that tends to cause free radical damage. Fructose, probably
        more than glucose, is protective against damage from endotoxin. Many stressors cause capillary leakage, allowing
        albumin and other blood components to enter extracellular spaces or to be lost in the urine, and this is a
        feature of diabetes, obesity, and a variety of inflammatory and degenerative diseases including Alzheimer's
        disease (Szekanecz and Koch, 2008; Ujiie, et al., 2003). Although the mechanism isn't understood, fructose
        supports capillary integrity; fructose feeding for 4 and 8 weeks caused a 56% and 51% reduction in capillary
        leakage, respectively (Chakir, et al., 1998; Plante, et al., 2003). The ability of the mitochondria to oxidize
        pyruvic acid and glucose is characteristically lost to some degree in cancer. When this oxidation fails, the
        disturbed redox balance of the cell will usually lead to the cell's death, but if it can survive, this balance
        favors growth and cell division, rather than differentiated function. This was Otto Warburg's discovery, that
        was rejected by official medicine for 75 years. Cancer researchers have become interested in this enzyme system
        that controls the oxidation of pyruvic acid (and thus sugar) by the mitochondria, since these enzymes are
        crucially defective in cancer cells (and also in diabetes). The chemical DCA, dichloroacetate, is effective
        against a variety of cancers, and it acts by reactivating the enzymes that oxidize pyruvic acid. Thyroid
        hormone, insulin, and fructose also activate these enzymes. These are the enzymes that are inactivated by
        excessive exposure to fatty acids, and that are involved in the progressive replacement of sugar oxidation by
        fat oxidation, during stress and aging, and in degenerative diseases; for example, a process that inactivates
        the energy-producing pyruvate dehydrogenase in Alzheimer's disease has been identified (Ishiguro, 1998).
        Niacinamide, by lowering free fatty acids and regulating the redox system, supporting sugar oxidation, is useful
        in the whole spectrum of metabolic degenerative diseases. A few times in the last 80 years, people (starting
        with Nasonov) have recognized that the hydrophobicity of a cell changes with its degree of excitation, and with
        its energy level. Recently, even in non-living physical-chemical systems, hydrophobicity and redox potential
        have been seen to vary together and to influence each other. Recent work shows how the oxidation of fatty acids
        contributes to the dissolution of mitochondria (Macchioni, et al., 2010). At first glance it might seem odd that
        the presence of fatty material could reduce the "fat loving" (lipophilic, equivalent to hydrophobic) property of
        a cell, but the fat used as fuel is in the form of fatty acids, which are soap-like, and spontaneously introduce
        "wetness" into the relatively water-resistant cell substance. The presence of fatty acids, impairing the last
        oxidative stage of respiration, increases the tendency of the mitochondrion to release its cytochrome c into the
        cell in a reduced form, leading to the apoptotic death of the cell. The oxidized form of the cytochrome is more
        hydrophobic, and stable. Burr didn't understand that it was his rats' high sugar diet, freed of the
        anti-oxidative unsaturated fatty acids, that caused their extremely high metabolic rate, but since that time
        many experiments have made it clear that it is specifically the fructose component of sucrose that is protective
        against the antimetabolic fats. Although Brown, et al., weren't focusing on the biological effects of sugar,
        their results are important in the history of sugar research because their work was done before the culture had
        been influenced by the development of the lipid theory of heart disease, and the later idea that fructose is
        responsible for increasing the blood lipids. In 1963 and 1964, experiments (Carroll, 1964) showed that the
        effects of glucose and fructose were radically affected by the type of fat in the diet. Although 0.6% of
        calories as polyunsaturated fat prevents the appearance of the Mead acid (which is considered to indicate a
        deficiency of essential fats) the "high fructose" diets consistently add 10% or more corn oil or other highly
        unsaturated fat to the diet. These large quantities of PUFA aren't necessary to prevent a deficiency, but they
        are needed to obscure the beneficial effects of fructose. Many studies have found that sucrose is less fattening
        than starch or glucose, that is, that more calories can be consumed without gaining weight. During exercise, the
        addition of fructose to glucose increases the oxidation of carbohydrate by about 50% (Jentjens and Jeukendrup,
        2005). In another experiment, rats were fed either sucrose or Coca-Cola and Purina chow, and were allowed to eat
        as much as they wanted (Bukowiecki, et al, 1983). They consumed 50% more calories without gaining extra weight,
        relative to the standard diet. Ruzzin, et al. (2005) observed rats given a 10.5% or 35% sucrose solution, or
        water, and observed that the sucrose increased their energy consumption by about 15% without increasing weight
        gain. Macor, et al. (1990) found that glucose caused a smaller increase in metabolic rate in obese people than
        in normal weight people, but that fructose increased their metabolic rate as much as it did that of the normal
        weight people. Tappy, et al. (1993) saw a similar increase in heat production in obese people, relative to the
        effect of glucose. Brundin, et al. (1993) compared the effects of glucose and fructose in healthy people, and
        saw a greater oxygen consumption with fructose, and also an increase in the temperature of the blood, and a
        greater increase in carbon dioxide production. These metabolic effects have led several groups to recommend the
        use of fructose for treating shock, the stress of surgery, or infection (e.g., Adolph, et al., 1995). The
        commonly recommended alternative to sugar in the diet is starch, but many studies show that it produces all of
        the effects that are commonly ascribed to sucrose and fructose, for example hyperglycemia (Villaume, et al.,
        1984) and increased weight gain. The addition of fructose to glucose "can markedly reduce hyperglycemia during
        intraportal glucose infusion by increasing net hepatic glucose uptake even when insulin secretion is
        compromised" (Shiota, et al., 2005). "Fructose appears most effective in those normal individuals who have the
        poorest glucose tolerance" (Moore, et al., 2000). Lipid peroxidation is involved in the degenerative diseases,
        and many publications argue that fructose increases it, despite the fact that it can increase the production of
        uric acid, which is a major component of our endogenous antioxidant system (e.g., Waring, et al., 2003). When
        rats were fed for 8 weeks on a diet with 18% fructose and 11% saturated fatty acids, the content of
        polyunsatured fats in the blood decreased, as they had in the Brown, et al., experiment, and their total
        antioxidant status was increased (Girard, et al., 2005). When stroke-prone spontaneously hypertensive rats were
        given 60% fructose, superoxide dismutase in their liver was increased, and the authors suggest that this "may
        constitute an early protective mechanism" (Brosnan and Carkner, 2008). When people were given a 300 calorie
        drink containing glucose, or fructose, or orange juice, those receiving the glucose had a large increase in
        oxidative and inflammatory stress (reactive oxygen species, and NF-kappaB binding), and those changes were
        absent in those receiving the fructose or orange juice (Ghanim, et al., 2007). One of the observations in Brown,
        et al., was that the level of phosphate in the serum decreased during the experimental diet. Several later
        studies show that fructose increases the excretion of phosphate in the urine, while decreasing the level in the
        serum. However, a common opinion is that it's only the phosphorylation of fructose, increasing the amount in
        cells, that causes the decrease in the serum; that could account for the momentary drop in serum phosphate
        during a fructose load, but--since there is only so much phosphate that can be bound to intracellular
        fructose--it can't account for the chronic depression of the serum phosphate on a continuing diet of fructose or
        sucrose. There are many reasons to think that a slight reduction of serum phosphate would be beneficial. It has
        been suggested that eating fruit is protective against prostate cancer, by lowering serum phosphate (Kapur,
        2000). The aging suppressing gene discovered in 1997, named after the Greek life-promoting goddess Klotho,
        suppresses the reabsorption of phosphate by the kidney (which is also a function of the parathyroid hormone),
        and inhibits the formation of the activated form of vitamin D, opposing the effect of the parathyroid hormone.
        In the absence of the gene, serum phosphate is high, and the animal ages and dies prematurely. In humans, in
        recent years a very close association has been has been documented between increased phosphate levels, within
        the normal range, and increased risk of cardiovascular disease. Serum phosphate is increased in people with
        osteoporosis (Gallagher, et al., 1980), and various treatments that lower serum phosphate improve bone
        mineralization, with the retention of calcium phosphate (Ma and Fu, 2010; Batista, et al., 2010; Kelly, et al.,
        1967; Parfitt, 1965; Kim, et al., 2003). At high altitude, or when taking a carbonic anhydrase inhibitor, there
        is more carbon dioxide in the blood, and the serum phosphate is lower; sucrose and fructose increase the
        respiratory quotient and carbon dioxide production, and this is probably a factor in lowering the serum
        phosphate. Fructose affects the body's ability to retain other nutrients, including magnesium, copper, calcium,
        and other minerals. Comparing diets with 20% of the calories from fructose or from cornstarch, Holbrook, et al.
        (1989) concluded "The results indicate that dietary fructose enhances mineral balance." Ordinarily, things (such
        as thyroid and vitamin D) which improve the retention of magnesium and other nutrients are considered good, but
        the fructose mythology allows researchers to conclude, after finding an increased magnesium balance, with either
        4% or 20% of energy from fructose (compared to cornstarch, bread, and rice), "that dietary fructose adversely
        affects macromineral homeostasis in humans." (Milne and Nielsen, 2000). Another study compared the effects of a
        diet with plain water, or water containing 13% glucose, or sucrose, or fructose, or high fructose corn syrup on
        the properties of rats' bones: Bone mineral density and mineral content, and bone strength, and mineral balance.
        The largest differences were between animals drinking the glucose and the fructose solutions. The rats getting
        the glucose had reduced phosphorus in their bones, and more calcium in their urine, than the rats that got
        fructose. "The results suggested that glucose rather than fructose exerted more deleterious effects on mineral
        balance and bone" (Tsanzi, et al., 2008). An older experiment compared two groups with an otherwise well
        balanced diet, lacking vitamin D, containing either 68% starch or 68% sucrose. A third group got the starch
        diet, but with added vitamin D. The rats on the vitamin D deficient starch diet had very low levels of calcium
        in their blood, and the calcium content of their bones was low, exactly what is expected with the vitamin D
        deficiency. However, the rats on the sucrose diet, also vitamin D deficient, had normal levels of calcium in
        their blood. The sucrose, unlike the starch, maintained claim homeostasis. A radioactive calcium tracer showed
        normal uptake by the bone, and also apparently normal bone development, although their bones were lighter than
        those receiving vitamin D. People have told me that when they looked for articles on fructose in PubMed they
        couldn't find anything except articles about its bad effects. There are two reasons for that. PubMed, like the
        earlier Index Medicus, represents the material in the National Library of Medicine, and is a medical, rather
        than a scientific, database, and there is a large amount of important research that it ignores. And because of
        the authoritarian and conformist nature of the medical profession, when a researcher observes something that is
        contrary to majority opinion, the title of the publication is unlikely to focus on that. In too many articles in
        medical journals, the title and conclusions positively misrepresent the data reported in the article. When the
        idea of "glycemic index" was being popularized by dietitians, it was already known that starch, consisting of
        chains of glucose molecules, had a much higher index than fructose and sucrose. The more rapid appearance of
        glucose in the blood stimulates more insulin, and insulin stimulates fat synthesis, when there is more glucose
        than can be oxidized immediately. If starch or glucose is eaten at the same time as polyunsaturated fats, which
        inhibit its oxidation, it will produce more fat. Many animal experiments show this, even when they are intending
        to show the dangers of fructose and sucrose. For example (Thresher, et al., 2000), rats were fed diets with 68%
        carbohydrate, 12% fat (corn oil), and 20% protein. In one group the carbohydrate was starch (cornstarch and
        maltodextrin, with a glucose equivalence of 10%), and in other groups it was either 68% sucrose, or 34% fructose
        and 34% glucose, or 34% fructose and 34% starch. (An interesting oddity, fasting triglycerides were highest in
        the fructose+starch group.) The weight of their fat pads (epididymal, retroperitoneal, and mesenteric) was
        greatest in the fructose+starch group, and least in the sucrose group. The starch group's fat was intermediate
        in weight between those of the sucrose and the fructose+glucose groups. At the beginning of the experimental
        diet, the average weight of the animals was 213.1 grams. After five weeks, the animals in the fructose+glucose
        group gained 164 grams, those in the sucrose group gained 177 grams, and those in the starch group gained 199.2
        grams. The animals ate as much of the diet as they wanted, and those in the sucrose group ate the least. The
        purpose of their study was to see whether fructose causes "glucose intolerance" and "insulin resistance." Since
        insulin stimulates appetite (Chance, et al, 1986; Dulloo and Girardier, 1989; Czech, 1988; DiBattista, 1983;
        Sonoda, 1983; Godbole and York, 1978), and fat synthesis, the reduced food consumption and reduced weight gain
        show that fructose was protecting against these potentially harmful effects of insulin. Much of the current
        concern about the dangers of fructose is focussed on the cornstarch-derived high fructose corn syrup, HFCS. Many
        studies assume that its composition is nearly all fructose and glucose. However, Wahjudi, et al. (2010) analyzed
        samples of it before and after hydrolyzing it in acid, to break down other carbohydrates present in it. They
        found that the carbohydrate content was several times higher than the listed values. "The underestimation of
        carbohydrate content in beverages may be a contributing factor in the development of obesity in children," and
        it's especially interesting that so much of it is present in the form of starch-like materials. Many people are
        claiming that fructose consumption has increased greatly in the last 30 or 40 years, and that this is
        responsible for the epidemic of obesity and diabetes. According to the USDA Economic Research Service, the 2007
        calorie consumption as flour and cereal products increased 3% from 1970, while added sugar calories decreased
        1%. Calories from meats, eggs, and nuts decreased 4%, from dairy foods decreased 3%, and calories from added
        fats increased 7%. The percentage of calories from fruits and vegetables stayed the same. The average person
        consumed 603 calories per day more in 2007 than in 1970. If changes in the national diet are responsible for the
        increase of obesity, diabetes, and the diseases associated with them, then it would seem that the increased
        consumption of fat and starch is responsible, and that would be consistent with the known effects of starches
        and polyunsaturated fats. In monkeys living in the wild, when their diet is mainly fruit, their cortisol is low,
        and it rises when they eat a diet with less sugar (Behie, et al., 2010). Sucrose consumption lowers ACTH, the
        main pituitary stress hormone (Klement, et al., 2009; Ulrich-Lai, et al., 2007), and stress promotes increased
        sugar and fat consumption (Pecoraro, et al., 2004). If animals' adrenal glands are removed, so that they lack
        the adrenal steroids, they choose to consume more sucrose (Laugero, et al., 2001). Stress seems to be perceived
        as a need for sugar. In the absence of sucrose, satisfying this need with starch and fat is more likely to lead
        to obesity. The glucocorticoid hormones inhibit the metabolism of sugar. Sugar is essential for brain
        development and maintenance. The effects of environmental stimulation and deprivation-stress can be detected in
        the thickness of the brain cortex in as little as 4 days in growing rats (Diamond, et al., 1976). These effects
        can persist through a lifetime, and are even passed on transgenerationally. Experimental evidence shows that
        polyunsaturated (omega-3) fats retard fetal brain development, and that sugar promotes it. These facts argue
        against some of the currently popular ideas of the evolution of the human brain based on ancestral diets of fish
        or meat, which only matters as far as those anthropological theories are used to argue against fruits and other
        sugars in the present diet. Honey has been used therapeutically for thousands of years, and recently there has
        been some research documenting a variety of uses, including treatment of ulcers and colitis, and other
        inflammatory conditions. Obesity increases mediators of inflammation, including the C-reactive protein (CRP) and
        homocysteine. Honey, which contains free fructose and free glucose, lowers CRP and homocysteine, as well as
        triglycerides, glucose, and cholesterol, while it increased insulin more than sucrose did (Al-Waili, 2004).
        Hypoglycemia intensifies inflammatory reactions, and insulin can reduce inflammation if sugar is available.
        Obesity, like diabetes, seems to involve a cellular energy deficiency, resulting from the inability to
        metabolize sugar. Sucrose (and sometimes honey) is increasingly being used to reduce pain in newborns, for minor
        things such as injections (Guala, et al., 2001; Okan, et al., 2007; Anand, et al., 2005; Schoen and Fischell,
        1991). It's also effective in adults. It acts by influencing a variety of nerve systems, and also reduces
        stress. Insulin is probably involved in sugar analgesia, as it is in inflammation, since it promotes entry of
        endorphins into the brain (Witt, et al., 2000). An extracellular phosphorylated fructose metabolite,
        diphosphoglycerate, has an essential regulatory effect in the blood; another fructose metabolite, fructose
        diphosphate, can reduce mast cell histamine release and protect against oxidative and hypoxic injury and
        endotoxic shock, and it reduces the expression of the inflammation mediators TNF-alpha, IL-6, nitric oxide
        synthase, and the activation of NF-kappaB, among other protective effects, and its therapeutic value is known,
        but its relation to dietary sugars hasn't been investigated. A daily diet that includes two quarts of milk and a
        quart of orange juice provides enough fructose and other sugars for general resistance to stress, but larger
        amounts of fruit juice, honey, or other sugars can protect against increased stress, and can reverse some of the
        established degenerative conditions. Refined granulated sugar is extremely pure, but it lacks all of the
        essential nutrients, so it should be considered as a temporary therapeutic material, or as an occasional
        substitute when good fruit isn't available, or when available honey is allergenic. <h3>

            <strong><strong>The Cancer Matrix</strong>&nbsp;&nbsp;</strong>&nbsp; &nbsp;It isn't hard to understand that
            in heart failure the heart is undergoing changes in a unitary way, with&nbsp;all parts of the organ
            affected, and that parallel changes are happening in the rest of the body, interacting with and contributing
            to the changes in the heart, so that heart failure is now considered to be a systemic disease. (Most doctors
            see the systemic nature of heart disease, at least to the extent of warning their patients to lower
            cholesterol and avoid thyroid hormone.) But if someone tells a cancer patient or an oncologist that cancer
            is a systemic disease, the thought will be flatly rejected as untrue. They have been taught that cancer is a
            disease of bad, mutated, cells, which have to be completely eradicated, and that the patient's general
            health is a separate issue.
        </p>
        <p>
            <span>&nbsp; &nbsp;The US government (NIH, CDC) provides a cancer curriculum to schools. For high school,
                grades 9-12, they explain that a series of gene mutations causes it. In grade school, the basic idea of
                the cancer curriculum is just to teach them to fear cancer and the sunlight which, according to the
                curriculum, seems to be a very important mutagen.</span>
            <span>&nbsp; &nbsp;The gene mutation theory of cancer is sustained by a broader mystique of "genetics" in
                our culture. Over 100 years ago, an ideology of chance and random changes in organisms was superimposed
                onto the theory of evolution. After 1944, when Avery, MacLeod and McCarty showed that strands of DNA
                carry hereditary information, the doctrine of random change took on a specific chemical meaning--changes
                in the sequence of bases in the DNA molecule. This made it easier to disregard the evidence of the
                inheritance of acquired changes, since chemical, even biochemical, reactions are usually interpreted
                statistically, with an assumption of randomness. If the changes in the DNA code are random, and not
                influenced by the organism's physiology and biochemistry, then the four nucleotides that make up DNA
                (abbreviated G, C, A, and T) should show a random composition, but in fact the ratio of GC pairs to AT
                pairs varies in different types of organism, and in mitochondrial DNA, the GC (guanine-cytosine) content
                corresponds closely to the rate of oxidative metabolism and longevity (Lehmann, et al.,
                2008).&nbsp;</span>
            <span>&nbsp;&nbsp;&nbsp;The official (government and American Cancer Society) view of cancer is that a tumor
                consists of the descendants of a single mutated cell. A current "proof" of this is that in a given
                tumor, all of the X chromosomes which are active have the same genetic composition, while in the rest of
                the organism, the X chromosome which remains active is a matter of chance. That shows, they argue, that
                the tumor must have developed from a cell in which that chromosome was active, not from a group of
                cells. However, non-random inactivation of X chromosomes is now known to occur, and that it involves
                epigenetic imprinting processes, such as methylation (Falconer, et al., 1982; Heard, 2004). Mary Lyon,
                the person who discovered that females inactivate one of their X chromosomes, has recognized the
                complexity of the process (Lyon, 2004). In arguing against the idea that the development of cancer is an
                epigenetic process, the cancer-gene people have invoked a process that responds to epigenetic
                influences.</span>
            <span>&nbsp;&nbsp;&nbsp;The assumption of randomness, and the assertions of the cancer doctors who subscribe
                to the doctrine, have had terrible effects on biology and medicine. Following the doctrine, their
                treatments must concentrate on eliminating every single cell of the cancer clone. Since surgery can't
                eliminate defective cells that have entered the blood stream, radiation and chemical toxins are logical
                necessities. Since mutations are random events, the person's general health is of little importance to
                the oncologist. Typically, they will tell the patient that their diet doesn't matter, except that they
                should avoid antioxidants if they are going to have radiation therapy.&nbsp;</span>
            <span>&nbsp;&nbsp;&nbsp; For centuries, the definition of a malignant tumor has been that it's one which
                will return after it has been cut out. In recent years, the definition has been extended to those that
                return after the original tumor has been eliminated by radiation or chemotherapy. The idea of a "cancer
                stem cell," an especially tough type of cell from the mutated clone, has been invoked to explain the
                reason for the regrowth of a tumor in an area that was treated with intense radiation. However, it's now
                clear that normal cells are attracted to an irradiated area (Klopp, et al., 2007; Kidd, et al., 2009).
                The recognition of a "bystander effect," in which radiation (or other--Mothersill and Seymour, 2009)
                injury to one cell injures near-by cells by signals from the injured cell, has led to the recognition
                that ordinary stem cells or repair cells entering an area where a tumor has been destroyed will be
                modified by the residual damage of cells in the area. The ability to recruit normal cells into a damaged
                area, the "cancer field," the way normal organs do, shows that tumors can be thought of as organ-like
                structures, and that knowledge of the organizing principles of normal organs might improve our knowledge
                of tumors. The idea that cancer is primarily a problem of organization isn't new: Johannes Muller, in
                the 19th century, and J.W. Orr, and D.W. Smithers, in the 1940s and 1950s, and many others, have
                suggested that something outside of the individual cell could cause the
                disorganization.&nbsp;&nbsp;</span>
            <span>&nbsp;&nbsp;&nbsp; Once it is accepted that cancer is a systemic disease, and that a tumor, or the
                place in the body where a tumor has been removed, is something more than a collection of defective
                cells, very different therapeutic approaches can be considered. Looking at the events in a failing
                heart, we can see that the potential repair cells recruited by the stressed heart are diverted by the
                conditions that they encounter there, and either die or become connective tissue cells, secreting
                collagen, rather than becoming new muscle cells.&nbsp;</span>
            <span>&nbsp;&nbsp;&nbsp; Something that everyone knows about tumors is that they are harder than the normal
                tissues in which they appear--they can be identified as lumps. Like the failing heart, they become
                harder than normal, and like the failing heart, the hardening can proceed to calcification. There has
                been general recognition that inflammation has a role in both heart disease and cancer, but the fact
                that chronic inflammation leads to fibrosis, and that fibrosis often leads to calcification, is still
                usually considered not to be relevant to understanding and treating cancer. The tissue hardness that
                allows oncologists to diagnose cancer (Huang and Ingber, 2005) is ignored when choosing treatments,
                which isn't surprising, since treatments that destroy cancer cells increase the production of
                collagen.</span>
            <span>&nbsp;&nbsp;&nbsp;Aspirin is commonly recommended for preventing heart attacks, because it helps to
                prevent abnormal blood clots, but it has other effects that are beneficial in heart disease, for example
                reducing the generalized fibrosis of the heart that develops after a heart attack (Kalkman, et al.,
                1995; Wu, et al., 2012). It also protects against fibrosis in other organs, by a variety of mechanisms,
                and this effect on the extracellular matrix seems to be one of ways in which it protects against cancer.
                DCA, dichloroacetate, the drug that has been in the news in recent years because it can stop cancer
                growth, by restoring the oxidation of glucose and stopping the aerobic production of lactic acid, has
                been found to reduce the fibrosis of a failing heart, by the same mechanism, restoring glucose
                oxidation. In general, substances that increase collagen production are promoters of cancer and
                contribute to the progression of heart failure, and other degenerative changes.</span>
            <span>&nbsp;&nbsp;&nbsp;The incidence of cancer increases exponentially with age, but when random mutations
                are seen as the cause of cancer, aging as an essential cause of cancer is disregarded. The total
                collagen content of the body increases with aging, and the stiffness of that collagen also increases.
                The total collagen content in cancer patients is higher than in people without cancer (Zimin, et al.,
                2010). This suggests that the processes in the body that produce aging are acting more intensely in
                those who develop cancer. As the collagen accumulates in the extracellular matrix, the whole body
                becomes more favorable for the appearance of cancer.&nbsp;</span>
            <span>&nbsp;&nbsp;&nbsp;Plastic surgeons have promoted the idea of injecting collagen into tissues with the
                argument that they are "replacing collagen lost with aging," but in fact collagen accumulates with
                aging. It is the greater compactness and stiffness of collagen in old skin that produces noticeable
                changes such as wrinkling. The difference between calf skin leather, used for soft gloves and purses,
                and cow hide, used for shoe soles and boots, illustrates the changes that occur with aging. Supermarkets
                used to categorize chickens as fryers and stewers, or stewing hens. The difference was the age and
                toughness, very young chickens could be cooked quickly, old laying hens had accumulated more collagen,
                and especially the cross-linked hardened collagen, and required long cooking to reduce the toughness.
                Old beef animals are usually sold as cheaper stew meat or hamburger, because the age-hardened collagen
                can make a steak too rubbery to chew if it's quickly cooked.&nbsp;</span>
            <span>&nbsp;&nbsp;&nbsp;In a healthy young organism, tissue injuries are repaired by processes reminiscent
                of Metchnikov's experiment in which he put a thorn into a jelly fish, and found that wandering cells,
                phagocytes, converged on the foreign object, surrounding it. If they couldn't eat it, they caused it to
                be expelled. The importance of that experiment was that it showed that injured tissues emit signals that
                attract certain types of cell. The process of removing damaged tissues by phagocytosis guides the
                formation of new tissue, starting with the secretion of collagen, which guides the maturation of the new
                cells.&nbsp;</span>
            <span>&nbsp;&nbsp;&nbsp;Around the middle of the last century, Hans Selye experimented with the antiseptic
                implantation of a short piece of a narrow glass tube under the skin of rats. The irritation from the
                glass object caused a collagenous capsule to be formed around it, in the well known "foreign body
                reaction." He found that a filament of tissue formed in the center of the tube, connecting the two ends
                of the capsule. The isolated tissue of the filament quickly underwent the degenerative changes seen in
                aged connective tissues, but if he periodically removed the fluid around it, and allowed fresh lymph
                fluid to fill the capsule, the filament retained a youthful elasticity, even as the rat aged. Isolation
                from the organism caused age-like degeneration to develop rapidly. When the organism can't remove a
                foreign object, the collagenous capsule that encloses it has a high probability of forming a cancer.
                This "foreign body carcinogenesis" has been studied for many years.&nbsp;&nbsp; &nbsp;</span>
            <span>&nbsp;&nbsp; &nbsp; &nbsp;</span>
            <span>&nbsp;&nbsp;&nbsp;Foreign body carcinogenesis is closely related to chemical carcinogenesis, radiation
                carcinogenesis, and hormonal carcinogenesis. Chemical carcinogens such as methylcholanthrene are
                irritating when injected, and stimulate collagen production. Neither type of carcinogenesis is always
                effective, because this collagen reaction can be protective, by isolating the irritant toxin (Zhang, et
                al., 2013). Radiation stimulates the secretion of collagen, and causes cross-linking that makes it
                stiffer, and slows its removal, leading to its accumulation (Sassi, et al., 2001). Some types of
                cross-linking block the ability of macrophages to remove it, creating something like a diffuse foreign
                body reaction. Estrogen, for example in the process of causing breast cancer, causes increased collagen
                synthesis. This is widely recognized, in the association of "breast density" (a high collagen content)
                with the risk of cancer. Estrogen also causes the formation of the enzymes that cross-link and stiffen
                the collagen, lysyl oxidase and transglutaminase(Sanada, et al., 1978; Campisi, et al., 2008;
                Balestrieri, et al., 2012).</span>
            <span>&nbsp;&nbsp;&nbsp;Although ultraviolet and ionizing radiation can act directly on collagen, to stiffen
                it, the greatest effect of the radiation is probably by reaction with relatively unstable components of
                tissues, such as polyunsaturated fatty acids, which then react with the collagen, cross-linking it
                (Igarashi, et al., 1989). Even in the absence of radiation, a deficiency of vitamin E accelerates the
                spontaneous decomposition of the unsaturated fats, accelerating the aging of collagen (Sundholm and
                Visapää, 1978 ). Many observations suggest that all of the collagen-aging carcinogenic factors interact
                synergistically.</span>
            <span>&nbsp;&nbsp;&nbsp;When cells are placed on a glass slide coated with collagen, they move to parts of
                the collagen that have been cross-linked, and they move from slightly cross-linked collagen to stiffer,
                more thoroughly cross-linked areas (Vincent, et al., 2013). When they are on stiffer collagen, they pull
                themselves more tightly toward it, continuously expending energy in the process. The muscle-like
                contraction of the cell causes it to become more rigid (Huang and Ingber, 2005). The increased hardness
                of even small tumors makes it possible to identify lymph node metastases from a breast cancer by touch,
                without removing them (Miyaji, et al., 1997).</span>
            <span>&nbsp;&nbsp;&nbsp;The increased energy cost of this "isotonic contraction" of the cell filaments
                requires more energy to sustain, and will tend to create lactic acid, the way intense muscle contraction
                does, while consuming oxygen at a higher rate. The increased lactic acid and decreased oxygen
                availability stimulate the synthesis of more collagen, the growth of new blood vessels, expression of
                enzymes for increasing the stiffness of the collagen, and other processes associated with inflammation,
                aging, and cancer. Blocking even one of these processes, the lysyl oxidase cross-linking enzyme, can
                reduce the invasiveness of a cancer (Lee, et al., 2011). Some observations (Tan, et al., 2010) show that
                the circulating cells of metastatic cancer are more rigid than other cells, which would increase the
                likelihood that they will block capillaries, creating oxygen-deprived nests of collagen-secreting
                cells.</span>
            <span>&nbsp;&nbsp;One of the substances produced by stressed cells that's involved in tumor induction,
                growth, and metastasis (Tanaka, et al., 2003; Datta, et al., 2010; Was, et al., 2010) is the enzyme heme
                oxygenase, which breaks down the essential component of respiratory enzymes, heme, producing carbon
                monoxide as a product, which inhibits cell respiration, increasing reliance on the glycolysis which
                produces lactic acid. If metastatic cells continue to produce this enzyme, this is likely to contribute
                to reconstituting the "cancer field," with increased HIF, hypoxia inducible factor, and a variety of
                other regulatory agents, each of which has its protective functions elsewhere, but which in combination
                can worsen the tumor.</span>
            <span>&nbsp;&nbsp;&nbsp;Substances that inhibit inflammation are likely to also inhibit excessive collagen
                synthesis, serotonin secretion, and the formation of estrogen. Besides aspirin, some effective
                substances are apigenin and naringenin, found in oranges and guavas. These flavonoids also inhibit the
                formation of nitric oxide and prostaglandins, which are important for inflammation and carcinogenesis
                (Liang, et al., 1999). Increased CO2, which has a variety of anti-inflammatory effects, can decrease
                collagen formation and tissue collagen content significantly (Ryu, et al., 2010).</span>
            <span>&nbsp;&nbsp;&nbsp;Deprivation of glucose and oxygen, which can be the local result of a cellular
                environment of condensed, stiffened collagen and the cellular tension and activation produced in
                response, combined with systemic stress that causes free fatty acids to interfere with the oxidation of
                sugar, activates enzymes that can dissolve collagen (MMP-2 and MMP-9). These enzymes are involved in
                metastasis, allowing cells to escape from the condensed collagen, but although they are normally thought
                of as enzymes that act outside of cells, they can also enter the cell's nucleus, where they degrade the
                DNA, causing the mutations and chromosomal abnormalities that are so characteristic of cancer (Hill, et
                al., 2012). Like glucose deprivation, exposure to 2-deoxyglucose, often used in tumor imaging, promotes
                metastasis (Schlappack, et al., 1991).</span>
            <span>&nbsp;&nbsp;&nbsp;The fact that cancer cells are stressed and damaged, and accumulate DNA damage,
                means that in a typical tumor there is a high rate of cell death. The number of apoptotic
                (disintegrating) cells in a tumor corresponds to the aggressiveness of the tumor (Vakkala, et al, 1999).
                In the 1940s and 1950s, Polezhaev demonstrated that dying cells stimulate cell renewal, and this is true
                in young and healthy organs, as well as in tumors.&nbsp;</span>
            <span>&nbsp;&nbsp;&nbsp;In 36% of women who had had a breast removed, from 7 to 22 years previously,
                identifiable (by the same tests used to diagnose breast cancer) cancer cells could be found circulating
                in their blood stream (Meng, et al., 2004). Tissue biopsies would be able to find the sources of those
                circulating cells, nests of similar cells throughout the body, which were dying about as fast as they
                were replicating. In 1969, Harry Rubin described an autopsy study which found that everyone over the age
                of 50 had at least one diagnosable cancer in some tissue. "Occult microscopic cancers are exceedingly
                common in the general population and are held in a dormant state by a balance between cell proliferation
                and cell death and also an intact host immune surveillance"(Goldstein and Mascitelli, 2011). These
                authors observed that the stress of surgery stimulates tumor growth, by various mechanisms, and that
                surgery increases the risk of developing cancer in apparently cancer-free patients.</span>
            <span>&nbsp;&nbsp;&nbsp;In 1956, Hardin Jones wrote "If one has cancer and opts to do nothing at all, he
                will live longer and feel better than if he undergoes radiation, chemotherapy or surgery, other than
                when used in immediate life-threatening situations." In the 1990s, a group of cancer specialists were
                asked what they would do if they were diagnosed with prostate cancer, and most of them said they would
                do nothing.&nbsp;</span>
            <span>&nbsp;&nbsp;&nbsp;The radical mastectomy, which removed massive amounts of apparently normal tissue as
                well as the breast tumor, was practiced for hundreds of years, and was the standard treatment for breast
                cancer until the 1980s, after G.W. Crile, Jr., had publicized the evidence showing that simply removing
                the tumor lump itself didn't cause a higher mortality rate, and that the surgery produced much less
                disability.&nbsp;</span>
            <span>&nbsp;&nbsp;&nbsp;Although the lumpectomy was eventually accepted by the profession, the evidence that
                the long term survival rate was higher when the surgery was done during the luteal phase in
                premenopausal women has been generally ignored, because the cancer ideology maintains that the fate of
                the cancer is in the cells, rather than in the patient's hormone balance.&nbsp;</span>
            <span>&nbsp;&nbsp;&nbsp;Because of the continual indoctrination about the importance of "early diagnosis to
                increase the chance of a cure," and the widely publicized "cure rates," it's easy for doctors to rush
                people into treatment, before they have time to study the issue. Dean Burk, who was a collaborator of
                Otto Warburg's for many years, was quoted in regard to the claims of the American Cancer Society that
                "They lie like scoundrels."</span>
            <span>&nbsp;&nbsp;&nbsp; In the 1970s, I noticed that the definitions of the features of uterine cancer had
                been changed recently, including as "cancer" things that had previously been classified as merely
                abnormal or precancerous.&nbsp;&nbsp;Reading more about the grading of cancer, I saw that other cancers
                had been defined more inclusively since the 1940s. Things that had previously not been called cancer
                were now being counted among the cancers that were cured by the various treatments, so, necessarily, the
                rate of cure had increased. The true situation could be seen by the age-specific mortality rate for each
                type of cancer. During the period when the "cure rates" were increasing, the age-specific death rates
                had increased. I think that's the sort of thing that Dean Burk had in mind.&nbsp;</span>
            <span>&nbsp; &nbsp;&nbsp;Nearly all of the studies of "cure rates" are comparisons of one
                ideologically-based and lucrative treatment against another ideologically-based and more or less
                lucrative treatment. When the cure rate, for example for breast cancer surgery, varies with the amount
                of progesterone in the body, there is very little interest in investigating the processes involved,
                because lucrative products aren't involved.</span>
            <span>&nbsp; &nbsp;When abnormal "metastatic" cells circulate in the blood or lymph, most of them die
                spontaneously when they stick in a place that doesn't support their growth. Many of the nests of cells
                that have started to grow probably regress spontaneously when conditions in the body change. Even large,
                clearly diagnosed tumors occasionally regress spontaneously. Aging and sickness tend to support the
                vicious cycles that lead to the progressive deterioration of the collagenous matrix. Stress (even
                anxiety-induced hyperventilation) produces alkalosis, and alkalosis favors increased collagen synthesis,
                while lower pH inhibits it (Frick, et al., 1997). For example, within a minute or two of
                hyperventilating, platelets release serotonin, and serotonin is a major promoter of collagen synthesis
                and fibrosis.&nbsp;</span>
            <span>&nbsp;&nbsp;&nbsp;The vicious cycles that promote cancer can be interrupted to some extent simply by
                reducing exposure to things that promote stress and inflammation--endotoxin, polyunsaturated fats, amino
                acid imbalance, nutritional deficiencies, ionizing radiation, estrogens--and maintaining optimal levels
                of things that protect against those--carbon dioxide, vitamin E, progesterone, light, aspirin, sugars,
                and thyroid hormone, for example.</span>

            <strong>PROGESTERONE INFORMATION</strong>
        </p>
        <p>
            Raymond Peat, MA, PhD (Univ. of Oregon)
        </p>
        <p>
            Endocrine Physiologist, specializing in hormonal changes in stress and aging
        </p>
        <p>
            Sixty years ago, progesterone was found to be the main hormone produced by the ovaries. Since it was
            necessary for fertility and for maintaining a healthy pregnancy, it was called the "pro-gestational
            hormone," and its name sometimes leads people to think that it isn't needed when you don't want to get
            pregnant. In fact, it is the most protective hormone the body produces, and the large amounts that are
            produced during pregnancy result from the developing baby's need for protection from the stressful
            environment. Normally, the brain contains a very high concentration of progesterone, reflecting its
            protective function for that most important organ. The thymus gland, the key organ of our immune system, is
            also profoundly dependent on progesterone.
        </p>
        <p>
            In experiments, progesterone was found to be the basic hormone of adaptation and of resistance to stress.
            The adrenal glands use it to produce their anti-stress hormones, and when there is enough progesterone, they
            don't have to produce the potentially harmful cortisone. In a progesterone deficiency, we produce too much
            cortisone, and excessive cortisone causes osteoporosis, aging of the skin, damage to brain cells, and the
            accumulation of fat, especially on the back and abdomen.
        </p>
        <p>
            Experiments have shown that progesterone relieves anxiety, improves memory, protects brain cells, and even
            prevents epileptic seizures. It promotes respiration, and has been used to correct emphysema. In the
            circulatory system, it prevents bulging veins by increasing the tone of blood vessels, and improves the
            efficiency of the heart. It reverses many of the signs of aging in the skin, and promotes healthy bone
            growth. It can relieve many types of arthritis, and helps a variety of immunological problems.
        </p>
        <p>
            If progesterone is taken dissolved in vitamin E, it is absorbed very efficiently, and distributed quickly to
            all of the tissues. If a woman has ovaries, progesterone helps them to produce both progesterone and
            estrogen as needed, and also helps to restore normal functioning of the thyroid and other glands. If her
            ovaries have been removed, progesterone should be taken consistently to replace the lost supply. A
            progesterone deficiency has often been associated with increased susceptibility to cancer, and progesterone
            has been used to treat some types of cancer.
        </p>
        <p>
            It is important to emphasize that progesterone is not just the hormone of pregnancy. To use it only "to
            protect the uterus" would be like telling a man he doesn't need testosterone if he doesn't plan to father
            children, except that progesterone is of far greater and more basic significance than testosterone. While
            men do naturally produce progesterone, and can sometimes benefit from using it, it is not a male hormone.
            Some people get that impression, because some physicians recommend combining estrogen with either
            testosterone or progesterone, to protect against some of estrogen's side effects, but progesterone is the
            body's natural complement to estrogen. Used alone, progesterone often makes it unnecessary to use estrogen
            for hot flashes or insomnia, or other symptoms of menopause.
        </p>
        <p>
            When dissolved in vitamin E, progesterone begins entering the blood stream almost as soon as it contacts any
            membrane, such as the lips, tongue, gums, or palate, but when it is swallowed, it continues to be absorbed
            as part of the digestive process. When taken with food, its absorption occurs at the same rate as the
            digestion and absorption of the food.
        </p>
        <p>
            <strong>PREGNENOLONE</strong>
        </p>
        <p>
            Pregnenolone, which is the raw material for producing many of the hormones of stress and adaptation, was
            known as early as 1934, but for several years it was considered to be an "inert" substance. A reason for
            this belief is that it was first tested on healthy young animals. Since these animals were already producing
            large amounts of pregnenolone (in the brain, adrenal glands, and gonads), additional pregnenolone had no
            effect.
        </p>

        <p>
            In the 1940s, pregnenolone was tested in people who were sick or under stress, and it was found to have a
            wide range of beneficial actions, but the drug industry never had much interest in it. Its very generality
            made it seem unlike a drug, and its natural occurrence made it impossible to patent. Thus, many synthetic
            variants, each with a more specialized action and some serious side effects, came to be patented and
            promoted for use in treating specific conditions. The drug companies created an atmosphere in which many
            people felt that each disease should have a drug, and each drug, a disease. The side effects of some of
            those synthetic hormones were so awful that many people came to fear them. For example, synthetic varieties
            of "cortisone" can destroy immunity, and can cause osteoporosis, diabetes, and rapid aging, with loss of
            pigment in the skin and hair, and extreme thinning of the skin.
        </p>
        <p>
            Natural pregnenolone is present in young people of both sexes at a very high concentration, and one reason
            for the large amount produced in youth is that it is one of our basic defenses against the harmful side
            effects that an imbalance of even our natural hormones can produce. In excess, natural cortisone or estrogen
            can be dangerous, but when there is an abundance of pregnenolone, their side effects are prevented or
            minimized.
        </p>
        <p>
            In a healthy young person or animal, taking even a large dose of pregnenolone has no hormone-like or
            drug-like action at all. It is unique in this way. But if the animal or person is under stress, and
            producing more cortisone than usual, taking pregnenolone causes the cortisone to come down to the normal
            level. After the age of 40 or 45, it seems that everyone lives in a state of continuous "stress," just as a
            normal part of aging. This coincides with the body's decreased ability to produce an abundance of
            pregnenolone.
        </p>
        <p>
            When aging rats are given a supplement of pregnenolone, it immediately improves their memory and general
            performance. Human studies, as early as the 1940s, have also demonstrated improved performance of ordinary
            tasks. It is now known that pregnenolone is one of the major hormones in the brain. It is produced by
            certain brain cells, as well as being absorbed into the brain from the blood. It protects brain cells from
            injury caused by fatigue, and an adequate amount has a calming effect on the emotions, which is part of the
            reason that it protects us from the stress response that leads to an excessive production of cortisone.

            Many people have noticed that pregnenolone has a "face-lifting" action. This effect seems to be produced by
            improved circulation to the skin, and by an actual contraction of some muscle-like cells in the skin. A
            similar effect can improve joint mobility in arthritis, tissue elasticity in the lungs, and even eyesight.
            Many studies have shown it to be protective of "fibrous tissues" in general, and in this connection it was
            proven to prevent the tumors that can be caused by estrogen.

            Pregnenolone is largely converted into two other "youth-associated" protective hormones, progesterone and
            DHEA. At the age of 30, both men and women produce roughly 30 to 50 mg. of pregnenolone daily. When taken
            orally, even in the powdered form, it is absorbed fairly well. One dose of approximately 300 mg (the size of
            an aspirin tablet) keeps acting for about a week, as absorption continues along the intestine, and as it is
            "recycled" in the body. Part of this long lasting effect is because it improves the body's ability to
            produce its own pregnenolone. It tends to improve function of the thyroid and other glands, and this
            "normalizing" effect on the other glands helps to account for its wide range of beneficial effects.

        <p><strong>DHEA: ANOTHER YOUTH-ASSOCIATED HORMONE</strong></p>

        <p>
            DHEA (dehydroepiandrosterone) has a technical-sounding name because it has never been identified with a
            single dominant function, in spite of its abundance in the body. Many researchers still think of it as a
            substance produced by the adrenal glands, but experiments show that animals without adrenals are able to
            produce it in normal amounts. Much of it is formed in the brain (from pregnenolone), but it is probably
            produced in other organs, including the skin. The brain contains a much higher concentration of DHEA than
            the blood does.
        </p>
        <p>
            In old age, we produce only about 5% as much as we do in youth. This is about the same decrease that occurs
            with progesterone and pregnenolone. The other hormones (for example, cortisone) do not decrease so much; as
            a result, our balance shifts continually during aging toward dominance by hormones such as cortisone, which
            use up more and more body substance, without rebuilding it. Protection against the toxic actions of these
            specialized hormones is a major function of DHEA and the other youth-associated hormones.
        </p>

        <p>
            For example, starvation, aging, and stress cause the skin to become thin and fragile. An excess of
            cortisone--whether it is from medical treatment, or from stress, aging, or malnutrition--does the same
            thing. Material from the skin is dissolved to provide nutrition for the more essential organs. Other organs,
            such as the muscles and bones, dissolve more slowly, but just as destructively, under the continued
            influence of cortisone. DHEA blocks these destructive effects of cortisone, and actively restores the normal
            growth and repair processes to those organs, strengthening the skin and bones and other organs. Stimulation
            of bone-growth by DHEA has been demonstrated in vitro (in laboratory tests), and it has been used to relieve
            many symptoms caused by osteoporosis and arthritis, even when applied topically in an oily solution.
        </p>
        <p>
            Estrogen is known to produce a great variety of immunological defects, and DHEA, apparently by its balancing
            and restorative actions, is able to correct some of those immunological defects, including some "autoimmune"
            diseases.
        </p>
        <p>
            It is established that DHEA protects against cancer, but it isn't yet understood how it does this. It
            appears to protect against the toxic cancer-producing effects of excess estrogen, but its anti-cancer
            properties probably involve many other functions.
        </p>
        <p>
            Diabetes can be produced experimentally by certain poisons which kill the insulin-producing cells in the
            pancreas. Rabbits were experimentally made diabetic, and when treated with DHEA their diabetes was cured. It
            was found that the insulin-producing cells had regenerated. Many people with diabetes have used brewer's
            yeast and DHEA to improve their sugar metabolism. In diabetes, very little sugar enters the cells, so
            fatigue is a problem. DHEA stimulates cells to absorb sugar and to burn it, so it increases our general
            energy level and helps to prevent obesity.
        </p>
        <p>
            Young people produce about 12 to 15 milligrams of DHEA per day, and that amount decreases by about 2 mg. per
            day for every decade after the age of 30. This is one of the reasons that young people eat more without
            getting fat, and tolerate cold weather better: DHEA, like the thyroid hormone, increases our heat production
            and ability to burn calories. At the age of 50, about 4 mg. of DHEA per day will usually restore the level
            of DHEA in the blood to a youthful level. It is important to avoid taking more than needed, since some
            people (especially if they are deficient in progesterone, pregnenolone, or thyroid) can turn the excess into
            estrogen or testosterone, and large amounts of those sex hormones can disturb the function of the thymus
            gland and the liver.
        </p>

        <p>
            People who have taken an excess of DHEA have been found to have abnormally high estrogen levels, and this
            can cause the liver to enlarge, and the thymus to shrink.
        </p>
        <p>
            One study has found that the only hormone abnormality in a groupt of Alzheimers patients' brains was an
            excess of DHEA. In cell culture, DHEA can cause changes in glial cells resembling those seen in the aging
            brain. These observations suggest that DHEA should be used with caution. Supplements of pregnenolone and
            thyroid seem to be the safest way to optimize DHEA production.

        hypothesis" IV. Events in the tissues V. Therapies VI. Diagnosis

        <strong>I. Respiratory defect</strong>

        Broda Barnes, more than 60 years ago, summed up the major effects of hypothyroidism on health very neatly when
        he pointed out that if hypothyroid people don't die young from infectious diseases, such as tuberculosis, they
        die a little later from cancer or heart disease. He did his PhD research at the University of Chicago, just a
        few years after Otto Warburg, in Germany, had demonstrated the role of a "respiratory defect" in cancer. At the
        time Barnes was doing his research, hypothyroidism was diagnosed on the basis of a low basal metabolic rate,
        meaning that only a small amount of oxygen was needed to sustain life. This deficiency of oxygen consumption
        involved the same enzyme system that Warburg was studying in cancer cells. Barnes experimented on rabbits, and
        found that when their thyroid glands were removed, they developed atherosclerosis, just as hypothyroid people
        did. By the mid-1930s, it was generally known that hypothyroidism causes the cholesterol level in the blood to
        increase; hypercholesterolemia was a diagnostic sign of hypothyroidism. Administering a thyroid supplement,
        blood cholesterol came down to normal exactly as the basal metabolic rate came up to the normal rate. The
        biology of atherosclerotic heart disease was basically solved before the second world war. Many other diseases
        are now known to be caused by respiratory defects. Inflammation, stress, immunodeficiency, autoimmunity,
        developmental and degenerative diseases, and aging, all involve significantly abnormal oxidative processes. Just
        brief oxygen deprivation triggers processes that lead to lipid peroxidation, producing a chain of other
        oxidative reactions when oxygen is restored. The only effective way to stop lipid peroxidation is to restore
        normal respiration. Now that dozens of diseases are known to involve defective respiration, the idea of
        thyroid's extremely broad range of actions is becoming easier to accept.

        <strong>II. 50 years of fraud</strong>

        Until the second world war, hypothyroidism was diagnosed on the basis of BMR (basal metabolic rate) and a large
        group of signs and symptoms. In the late 1940s, promotion of the (biologically inappropriate) PBI (protein-bound
        iodine) blood test in the U.S. led to the concept that only 5% of the population were hypothyroid, and that the
        40% identified by "obsolete" methods were either normal, or suffered from other problems such as sloth and
        gluttony, or "genetic susceptibility" to disease. During the same period, thyroxine became available, and in
        healthy young men it acted "like the thyroid hormone." Older practitioners recognized that it was not
        metabolically the same as the traditional thyroid substance, especially for women and seriously hypothyroid
        patients, but marketing, and its influence on medical education, led to the false idea that the standard Armour
        thyroid USP wasn't properly standardized, and that certain thyroxine products were; despite the fact that both
        of these were shown to be false. By the 1960s, the PBI test was proven to be irrelevant to the diagnosis of
        hypothyroidism, but the doctrine of 5% hypothyroidism in the populaton became the basis for establishing the
        norms for biologically meaningful tests when they were introduced. Meanwhile, the practice of measuring serum
        iodine, and equating it with "thyroxine the thyroid hormone," led to the practice of examining only the iodine
        content of the putative glandular material that was offered for sale as thyroid USP. This led to the
        substitution of materials such as iodinated casein for desiccated thyroid in the products sold as thyroid USP.
        The US FDA refused to take action, because they held that a material's iodine content was enough to identify it
        as "thyroid USP." In this culture of misunderstanding and misrepresentation, the mistaken idea of
        hypothyroidism's low incidence in the population led to the acceptance of dangerously high TSH (thyroid
        stimulating hormone) activity as "normal." Just as excessive FSH (follicle stimulating hormone) has been shown
        to have a role in ovarian cancer, excessive stimulation by TSH produces disorganization in the thyroid gland.

        <strong>III. Tests &amp; the "free hormone hypothesis"</strong>

        After radioactive iodine became available, many physicians would administer a dose, and then scan the body with
        a Geiger counter, to see if it was being concentrated in the thyroid gland. If a person had been eating
        iodine-rich food (and iodine was used in bread as a preservative/dough condition, and was present in other foods
        as an accidental contaminant), they would already be over saturated with iodine, and the gland would fail to
        concentrate the iodine. The test can find some types of metastatic thyroid cancer, but the test generally wasn't
        used for that purpose. Another expensive and entertaining test has been the thyrotropin release hormone (TRH)
        test, to see if the pituitary responds to it by increasing TSH production. A recent study concluded that "TRH
        test gives many misleading results and has an elevated cost/benefit ratio as compared with the characteristic
        combination of low thyroxinemia and non-elevated TSH." (Bakiri, Ann. Endocr (Paris) 1999), but the technological
        drama, cost, and danger (Dokmetas, et al., J Endocrinol Invest 1999 Oct; 22(9): 698-700) of this test is going
        to make it stay popular for a long time. If the special value of the test is to diagnose a pituitary
        abnormality, it seems intuitively obvious that overstimulating the pituitary might not be a good idea (e.g., it
        could cause a tumor to grow). Everything else being equal, as they say, looking at the amount of thyroxine and
        TSH in the blood can be informative. The problem is that it's just a matter of faith that "everything else" is
        going to be equal. The exceptions to the "rule" regarding normal ranges for thyroxine and TSH have formed the
        basis for some theories about "the genetics of thyroid resistance," but others have pointed out that, when a few
        other things are taken into account, abnormal numbers for T4, T3, TSH, can be variously explained. The actual
        quantity of T3, the active thyroid hormone, in the blood can be measured with reasonable accuracy (using
        radioimmunoassay, RIA), and this single test corresponds better to the metabolic rate and other meaningful
        biological responses than other standard tests do. But still, this is only a statistical correspondence, and it
        doesn't indicate that any particular number is right for a particular individual. Sometimes, a test called the
        RT3U, or resin T3 uptake, is used, along with a measurement of thyroxine. A certain amount of radioactive T3 is
        added to a sample of serum, and then an adsorbent material is exposed to the mixture of serum and radioactive
        T3. The amount of radioactivity that sticks to the resin is called the T3 uptake. The lab report then gives a
        number called T7, or free thyroxine index. The closer this procedure is examined, the sillier it looks, and it
        looks pretty silly on its face.. The idea that the added radioactive T3 that sticks to a piece of resin will
        correspond to "free thyroxine," is in itself odd, but the really interesting question is, what do they mean by
        "free thyroxine"? Thyroxine is a fairly hydrophobic (insoluble in water) substance, that will associate with
        proteins, cells, and lipoproteins in the blood, rather than dissolving in the water. Although the Merck Index
        describes it as "insoluble in water," it does contain some polar groups that, in the right (industrial or
        laboratory) conditions, can make it slightly water soluble. This makes it a little different from progesterone,
        which is simply and thoroughly insoluble in water, though the term "free hormone" is often applied to
        progesterone, as it is to thyroid. In the case of progesterone, the term "free progesterone" can be traced to
        experiments in which serum containing progesterone (bound to proteins) is separated by a (dialysis) membrane
        from a solution of similar proteins which contain no progesterone. Progesterone "dissolves in" the substance of
        the membrane, and the serum proteins, which also tend to associate with the membrane, are so large that they
        don't pass through it. On the other side, proteins coming in contact with the membrane pick up some
        progesterone. The progesterone that passes through is called "free progesterone," but from that experiment,
        which gives no information on the nature of the interactions between progesterone and the dialysis membrane, or
        about its interactions with the proteins, or the proteins' interactions with the membrane, nothing is revealed
        about the reasons for the transmission or exchange of a certain amount of progesterone. Nevertheless, that type
        of experiment is used to interpret what happens in the body, where there is nothing that corresponds to the
        experimental set-up, except that some progesterone is associated with some protein. The idea that the "free
        hormone" is the active form has been tested in a few situations, and in the case of the thyroid hormone, it is
        clearly not true for the brain, and some other organs. The protein-bound hormone is, in these cases, the active
        form; the associations between the "free hormone" and the biological processes and diseases will be completely
        false, if they are ignoring the active forms of the hormone in favor of the less active forms. The conclusions
        will be false, as they are when T4 is measured, and T3 ignored. Thyroid-dependent processes will appear to be
        independent of the level of thyroid hormone; hypothyroidism could be caller hyperthyroidism. Although
        progesterone is more fat soluble than cortisol and the thyroid hormones, the behavior of progesterone in the
        blood illustrates some of the problems that have to be considered for interpreting thyroid physiology. When red
        cells are broken up, they are found to contain progesterone at about twice the concentration of the serum. In
        the serum, 40 to 80% of the progesterone is probably carried on albumin. (Albumin easily delivers its
        progesterone load into tissues.) Progesterone, like cholesterol, can be carried on/in the lipoproteins, in
        moderate quantities. This leaves a very small fraction to be bound to the "steroid binding globulin." Anyone who
        has tried to dissolve progesterone in various solvents and mixtures knows that it takes just a tiny amount of
        water in a solvent to make progesterone precipitate from solution as crystals; its solubility in water is
        essentially zero. "Free" progesterone would seem to mean progesterone not attached to proteins or dissolved in
        red blood cells or lipoproteins, and this would be zero. The tests that purport to measure free progesterone are
        measuring something, but not the progesterone in the watery fraction of the serum. The thyroid hormones
        associate with three types of simple proteins in the serum: Transthyretin (prealbumin), thyroid binding
        globulin, and albumin. A very significant amount is also associated with various serum lipoproteins, including
        HDL, LDL, and VLDL (very low density lipoproteins). A very large portion of the thyroid in the blood is
        associated with the red blood cells. When red cells were incubated in a medium containing serum albumin, with
        the cells at roughly the concentration found in the blood, they retained T3 at a concentration 13.5 times higher
        than that of the medium. In a larger amount of medium, their concentration of T3 was 50 times higher than the
        medium's. When laboratories measure the hormones in the serum only, they have already thrown out about 95% of
        the thyroid hormone that the blood contained. The T3 was found to be strongly associated with the cells'
        cytoplasmic proteins, but to move rapidly between the proteins inside the cells and other proteins outside the
        cells. When people speak of hormones travelling "on" the red blood cells, rather than "in" them, it is a
        concession to the doctrine of the impenetrable membrane barrier. Much more T3 bound to albumin is taken up by
        the liver than the small amount identified in vitro as free T3 (Terasaki, et al., 1987). The specific binding of
        T3 to albumin alters the protein's electrical properties, changing the way the albumin interacts with cells and
        other proteins. (Albumin becomes electrically more positive when it binds the hormone; this would make the
        albumin enter cells more easily. Giving up its T3 to the cell, it would become more negative, making it tend to
        leave the cell.) This active role of albumin in helping cells take up T3 might account for its increased uptake
        by the red cells when there were fewer cells in proportion to the albumin medium. This could also account for
        the favorable prognosis associated with higher levels of serum albumin in various sicknesses. When T3 is
        attached chemically (covalently, permanently) to the outside of red blood cells, apparently preventing its entry
        into other cells, the presence of these red cells produces reactions in other cells that are the same as some of
        those produced by the supposedly "free hormone." If T3 attached to whole cells can exert its hormonal action,
        why should we think of the hormone bound to proteins as being unable to affect cells? The idea of measuring the
        "free hormone" is that it supposedly represents the biologically active hormone, but in fact it is easier to
        measure the biological effects than it is to measure this hypothetical entity. Who cares how many angels might
        be dancing on the head of a pin, if the pin is effective in keeping your shirt closed?

        <strong>IV. Events in the tissues</strong>

        Besides the effects of commercial deception, confusion about thyroid has resulted from some biological clich"s.
        The idea of a "barrier membrane" around cells is an assumption that has affected most people studying cell
        physiology, and its effects can be seen in nearly all of the thousands of publications on the functions of
        thyroid hormones. According to this idea, people have described a cell as resembling a droplet of a watery
        solution, enclosed in an oily bag which separates the internal solution from the external watery solution. The
        clich" is sustained only by neglecting the fact that proteins have a great affinity for fats, and fats for
        proteins; even soluble proteins, such as serum albumin, often have interiors that are extremely fat-loving.
        Since the structural proteins that make up the framework of a cell aren't "dissolved in water" (they used to be
        called "the insoluble proteins"), the lipophilic phase isn't limited to an ultramicroscopically thin surface,
        but actually constitutes the bulk of the cell. Molecular geneticists like to trace their science from a 1944
        experiment that was done by Avery., et al. Avery's group knew about an earlier experiment, that had demonstrated
        that when dead bacteria were added to living bacteria, the traits of the dead bacteria appeared in the living
        bacteria. Avery's group extracted DNA from the dead bacteria, and showed that adding it to living bacteria
        transferred the traits of the dead organisms to the living. In the 1930s and 1940s, the movement of huge
        molecules such as proteins and nucleic acids into cells and out of cells wasn't a big deal; people observed it
        happening, and wrote about it. But in the 1940s the idea of the barrier membrane began gaining strength, and by
        the 1960s nothing was able to get into cells without authorization. At present, I doubt that any molecular
        geneticist would dream of doing a gene transplant without a "vector" to carry it across the membrane barrier.
        Since big molecules are supposed to be excluded from cells, it's only the "free hormone" which can find its
        specific port of entry into the cell, where another clich" says it must travel into the nucleus, to react with a
        specific site to activate the specific genes through which its effects will be expressed. I don't know of any
        hormone that acts that way. Thyroid, progesterone, and estrogen have many immediate effects that change the
        cell's functions long before genes could be activated. Transthyretin, carrying the thyroid hormone, enters the
        cell's mitochondria and nucleus (Azimova, et al., 1984, 1985). In the nucleus, it immediately causes generalized
        changes in the structure of chromosomes, as if preparing the cell for major adaptive changes. Respiratory
        activation is immediate in the mitochondria, but as respiration is stimulated, everything in the cell responds,
        including the genes that support respiratory metabolism. When the membrane people have to talk about the entry
        of large molecules into cells, they use terms such as "endocytosis" and "translocases," that incorporate the
        assumption of the barrier. But people who actually investigate the problem generally find that "diffusion,"
        "codiffusion," and absorption describe the situation adequately (e.g., B.A. Luxon, 1997; McLeese and Eales,
        1996). "Active transport" and "membrane pumps" are ideas that seem necessary to people who haven't studied the
        complex forces that operate at phase boundaries, such as the boundary between a cell and its environment.

        <strong>V. Therapy</strong>

        Years ago it was reported that Armour thyroid, U.S.P., released T3 and T4, when digested, in a ratio of 1:3, and
        that people who used it had much higher ratios of T3 to T4 in their serum, than people who took only thyroxine.
        The argument was made that thyroxine was superior to thyroid U.S.P., without explaining the significance of the
        fact that healthy people who weren't taking any thyroid supplement had higher T3:T4 ratios than the people who
        took thyroxine, or that our own thyroid gland releases a high ratio of T3 to T4. The fact that the T3 is being
        used faster than T4, removing it from the blood more quickly than it enters from the thyroid gland itself,
        hasn't been discussed in the journals, possibly because it would support the view that a natural glandular
        balance was more appropriate to supplement than pure thyroxine. The serum's high ratio of T4 to T3 is a
        pitifully poor argument to justify the use of thyroxine instead of a product that resembles the proportion of
        these substances secreted by a healthy thyroid gland, or maintained inside cells. About 30 years ago, when many
        people still thought of thyroxine as "the thryoid hormone," someone was making the argument that "the thyroid
        hormone" must work exclusively as an activator of genes, since most of the organ slices he tested didn't
        increase their oxygen consumption when it was added. In fact, the addition of thyroxine to brain slices
        suppressed their respiration by 6% during the experiment. Since most T3 is produced from T4 in the liver, not in
        the brain, I think that experiment had great significance, despite the ignorant interpretation of the author. An
        excess of thyroxine, in a tissue that doesn't convert it rapidly to T3, has an antithyroid action. (See Goumaz,
        et al, 1987.) This happens in many women who are given thyroxine; as their dose is increased, their symptoms get
        worse. The brain concentrates T3 from the serum, and may have a concentration 6 times higher than the serum
        (Goumaz, et al., 1987), and it can achieve a higher concentration of T3 than T4. It takes up and concentrates
        T3, while tending to expel T4. Reverse T3 (rT3) doesn't have much ability to enter the brain, but increased T4
        can cause it to be produced in the brain. These observations suggest to me that the blood's T3:T4 ratio would be
        very "brain favorable" if it approached more closely to the ratio formed in the thyroid gland, and secreted into
        the blood. Although most synthetic combination thyroid products now use a ratio of four T4 to one T3, many
        people feel that their memory and thinking are clearer when they take a ratio of about three to one. More active
        metabolism probably keeps the blood ratio of T3 to T4 relatively high, with the liver consuming T4 at about the
        same rate that T3 is used. Since T3 has a short half life, it should be taken frequently. If the liver isn't
        producing a noticeable amount of T3, it is usually helpful to take a few micorgrams per hour. Since it restores
        respiration and metabolic efficiency very quickly, it isn't usually necessary to take it every hour or two, but
        until normal temperature and pulse have been achieved and stabilized, sometimes it's necessary to take it four
        or more times during the day. T4 acts by being changed to T3, so it tends to accumulate in the body, and on a
        given dose, usually reaches a steady concentration after about two weeks. An effective way to use supplements is
        to take a combination T4-T3 dose, e.g., 40 mcg of T4 and 10 mcg of T3 once a day, and to use a few mcg of T3 at
        other times in the day. Keeping a 14-day chart of pulse rate and temperature allows you to see whether the dose
        is producing the desired response. If the figures aren't increasing at all after a few days, the dose can be
        increased, until a gradual daily increment can be seen, moving toward the goal at the rate of about 1/14 per day

        <strong>VI. Diagnosis</strong>

        In the absence of commercial techniques that reflect thyroid physiology realistically, there is no valid
        alternative to diagnosis based on the known physiological indicators of hypothyroidism and hyperthyroidism. The
        failure to treat sick people because of one or another blood test that indicates "normal thyroid function," or
        the destruction of patients' healthy thyroid glands because one of the tests indicates hyperthyroidism, isn't
        acceptable just because it's the professional standard, and is enforced by benighted state licensing boards.
        Toward the end of the twentieth century, there has been considerable discussion of "evidence-based medicine."
        Good judgment requires good information, but there are forces that would over-rule individual judgment as to
        whether published information is applicable to certain patients. In an atmosphere that sanctions prescribing
        estrogen or insulin without evidence of an estrogen deficiency or insulin deficiency, but that penalizes
        practitioners who prescribe thyroid to correct symptoms, the published "evidence" is necessarily heavily biased.
        In this context, "meta-analysis" becomes a tool of authoritarianism, replacing the use of judgment with the
        improper use of statistical analysis. Unless someone can demonstrate the scientific invalidity of the methods
        used to diagnose hypothyroidism up to 1945, then they constitute the best present evidence for evaluating
        hypothyroidism, because all of the blood tests that have been used since 1950 have been.shown to be, at best,
        very crude and conceptually inappropriate methods. Thomas H. McGavack's 1951 book, The Thyroid, was
        representative of the earlier approach to the study of thyroid physiology. Familiarity with the different
        effects of abnormal thyroid function under different conditions, at different ages, and the effects of gender,
        were standard parts of medical education that had disappeared by the end of the century. Arthritis,
        irregularities of growth, wasting, obesity, a variety of abnormalities of the hair and skin, carotenemia,
        amenorrhea, tendency to miscarry, infertility in males and females, insomnia or somnolence, emphysema, various
        heart diseases, psychosis, dementia, poor memory, anxiety, cold extremities, anemia, and many other problems
        were known reasons to suspect hypothyroidism. If the physician didn't have a device for measuring oxygen
        consumption, estimated calorie intake could provide supporting evidence. The Achilles' tendon reflex was another
        simple objective measurement with a very strong correlation to the basal metabolic rate. Skin electrical
        resistance, or whole body impedance wasn't widely accepted, though it had considerable scientific validity. A
        therapeutic trial was the final test of the validity of the diagnosis: If the patient's symptoms disappeared as
        his temperature and pulse rate and food intake were normalized, the diagnostic hypothesis was confirmed. It was
        common to begin therapy with one or two grains of thyroid, and to adjust the dose according to the patient's
        response. Whatever objective indicator was used, whether it was basal metabolic rate, or serum cholesterol. or
        core temperature, or reflex relaxation rate, a simple chart would graphically indicate the rate of recovery
        toward normal health.

        template activity of chromatin was studied. It was found that the values of binding constants of TBPA for T3 and
        T4 are 2 X 10(-11) M and 5 X 10(-10) M, respectively. The receptors isolated from 0.4 M KCl extract of chromatin
        and mitochondria as well as hormone-bound TBPA cause similar effects on the template activity of chromatin.
        Based on experimental results and the previously published comparative data on the structure of TBPA, nuclear,
        cytoplasmic and mitochondrial receptors of thyroid hormones as well as on translocation across the plasma
        membrane and intracellular transport of TBPA, a conclusion was drawn, which suggested that TBPA is the "core" of
        the true thyroid hormone receptor. It was shown that T3-bound TBPA caused histone H1-dependent conformational
        changes in chromatin. Based on the studies with the interaction of the TBPA-T3 complex with spin-labeled
        chromatin, a scheme of functioning of the thyroid hormone nuclear receptor was proposed. [The nature of thyroid

        liver were studied. It was found that the external mitochondrial membranes and matrix contain a protein whose
        electrophoretic mobility is similar to that of thyroxine-binding blood serum prealbumin (TBPA) and which binds
        either T4 or T3. This protein is precipitated by monospecific antibodies against TBPA. The internal
        mitochondrial membrane has two proteins able to bind thyroid hormones, one of which is localized in the cathode
        part of the gel and binds only T3, while the second one capable of binding T4 rather than T3 and possessing the
        electrophoretic mobility similar to that of TBPA. Radioimmunoprecipitation with monospecific antibodies against
        TBPA revealed that this protein also the antigenic determinants common with those of TBPA. The in vivo
        translocation of 125I-TBPA into submitochondrial fractions was studied. The analysis of densitograms of
        submitochondrial protein fraction showed that both TBPA and hormones are localized in the same protein
        fractions. Electron microscopic autoradiography demonstrated that 125I-TBPA enters the cytoplasm through the
        external membrane and is localized on the internal mitochondrial membrane and matrix. [The nature of thyroid

            Tissue-bound estrogen in aging
        </h1>

        <em><p>
                The "Estrogen Replacement" industry is based on the doctrine that a woman's tissues are depleted of
                estrogen after menopause. This doctrine is false.
            </p>
            <p>
                The concentration of a hormone in the blood doesn't directly represent the concentration in the various
                organs.
            </p>
            <p>
                The amount of estrogen in tissue is decreased when progesterone is abundant. In the absence of
                progesterone, tissues retain estrogen even when there is little estrogen circulating in the blood.
            </p>

            <p>
                Many things suggest an increased estrogenic activity at menopause. For example, melatonin decreases
                sharply at puberty when estrogen increases, and then it decreases again at menopause. Prolactin
                (stimulated by estrogen) increases around puberty, and instead of decreasing at menopause, it often
                increases, and its increase is associated with osteoporosis and other age-related symptoms.
            </p>
            <p>
                Estrogen is produced in many tissues by the enzyme aromatase, even in the breast and endometrium,
                although these are considered "target tissues" rather than endocrine glands. Aromatase increases with
                aging.
            </p>
            <p>
                Estrogen is inactivated, mainly in the liver and brain, by being made water soluble by the attachment of
                glucuronic acid and/or sulfuric acid.
            </p>
            <p>
                Estrogen's concentration in a particular tissue depends on many things, including its affinity or
                binding strength for components of that tissue, relative to its affinity for the blood; the activity in
                that tissue of the aromatase enzyme, which converts androgens to estrogen; the activity of the
                glucuronidase enzyme, that converts water-soluble estrogen glucuronides into the oil soluble active
                forms of estrogen; and the sulfatases and several other enzymes that modify the activity and solubility
                of the estrogens. The "estrogen receptors," proteins which bind estrogens in cells, are inactivated by
                progesterone, and activated by many physical and chemical conditions.
            </p>
            <p>
                Inflammation activates beta-glucuronidase, and antiinflammatory substances such as aspirin reduce many
                of estrogen's effects.

            Doctrines are admitted into the "scientific canon" by those who have the power of censorship. In astronomy,
            Halton Arp's discovery of "anomalous" galactic red-shifts is practically unknown, because the journal
            editors say the observations are "just anomalies," or that the theories which could explain them are
            unconventional; but the actual problem is that they are strong evidence against The Big Bang, Hubble's Law,
            and the Expanding Universe. American science, since the 1940s, has probably been the most censored and
            doctrinaire in the world.
        </p>
        <p>
            Gilbert Ling's revolution in cell biology remains outside the canon, despite the profound influence of MRI,
            which grew directly out of his view of the cell, because his work provided conclusive evidence that cells
            are not regulated by "semipermeable membranes and membrane pumps." Every field of science is ruled by a
            doctrinaire establishment.
        </p>
        <p>
            Charles E. Brown-S"quard (1817-94) was a physiologist who pioneered scientific endocrinology, but who was
            ridiculed because of his claim that extracts of animal glands had an invigorating effect when injected. His
            place in the scientific canon is mainly as an object of ridicule, and the details of his case are perfectly
            representative of the way our "canon" has been constructed. The argument for dismissing his observations was
            that he used a water extract of testicles, and, according to the 20th century American biologists,
            testosterone is not water soluble, and so the water extract would have "contained no hormone." The argument
            is foolish, because living organs contain innumerable substances that will solublize oily molecules, but
            also because Brown-Sequard was describing an effect that wasn"t necessarily limited to a single chemical
            substance. (The transplanting of living cells to repair tissues is finally being accepted, but the pioneers
            in promoting tissue regeneration or repair with the transplantation of living, dead, or stressed cells--V.
            Filatov, L.V. Polezhaev, W.T. Summerlin, for example--were simply written out of history.)
        </p>
        <p>
            If Brown-S"quard"s extract couldn"t work because testosterone isn"t soluble in water, then what are we to
            think of the thousands of medical publications that talk about "free hormones" as the only active hormones?
            ("Free hormone" is defined as the hormone that isn"t bound to a transporting protein, with the more or less
            explicit idea that it is dissolved in the water of the plasma or extracellular fluid.) Brown-S"quard"s
            tissue extracts would have contained solublizing substances including proteins and phospholipids, so the
            oily hormones would certainly be present (and active) in his extracts. But the thousands of people who
            ridiculed him committed themselves to the fact that steroid hormones are insoluble in water. By their own
            standard, they are selling an impossibility when they do calculations to reveal the amount of "free
            hormone," as something distinct from the protein bound hormone, in the patient"s blood.
        </p>

        <p>
            The immense Hormone Replacement Therapy industry--which Brown-S"quard"s experiments foreshadowed--is based
            on the fact that the concentrations of some hormones in the blood serum decrease with aging.
        </p>
        <p>
            At first, it was assumed that the amount of the hormone in the blood corresponded to the effectiveness of
            that hormone. Whatever was in the blood was being delivered to the "target tissues." But as the idea of
            measuring "protein bound iodine" (PBI) to determine thyroid function came into disrepute (because it never
            had a scientific basis at all), new ideas of measuring "active hormones" came into the marketplace, and
            currently the doctrine is that the "bound" hormones are inactive, and the active hormones are "free." The
            "free" hormones are supposed to be the only ones that can get into the cells to deliver their signals, but
            the problem is that "free hormones" exist only in the imagination of people who interpret certain lab tests,
            as I discussed in the newsletter on thyroid tests (May, 2000).
        </p>
        <p>
            In the 1960s and 1970s, when the PBI test was disappearing, there was intense interest in--a kind of mania
            regarding--the role of "membranes" in regulating cell functions, and the membrane was still seen by most
            biologists as the "semipermeable membrane" which, "obviously," would exclude molecules as large as albumin
            and the other proteins that carry thyroid and other hormones in the blood. (In reality, and experimental
            observations, albumin and other proteins enter cells more or less freely, depending on prevailing
            conditions.) The membrane doctrine led directly to the "free hormone" doctrine.
        </p>
        <p>
            This issue, of arguing about which form of a hormone is the "active" form, has to do with explaining how
            much of the blood-carried hormone is going to get into the "target tissues." If the membrane is a
            "semipermeable" barrier to molecules such as hormones, then specific receptors and transporters will be
            needed. If the concentration of a hormone inside the cell is higher than that in the blood, a "pump" will
            usually be invoked, to produce an "active transport" of the hormone against its concentration gradient.
        </p>
        <p>
            <strong>But if the membrane regulates the passage of hormones from blood to tissue cells, and especially if
                pumps are needed to move the hormone into the cell, how relevant is the measurement of hormones in the
                blood?</strong>
        </p>
        <p>
            Within the blood, progesterone and thyroid hormone (T3) are much more concentrated in the red blood cells
            than in the serum. Since it isn"t likely that red blood cells are "targets" for the sex hormones, or for
            progesterone or even thyroid, their concentration "against their gradient" in these cells suggests that a
            simple distribution by solubility is involved. Oily substances just naturally tend to concentrate inside
            cells because of their insolubility in the watery environment of the plasma and extracellular fluid.
            Proteins that have "oily" regions effectively bind oily molecules, such as fats and steroids. Even red blood
            cells have such proteins.
        </p>

        <p>
            In the case of oil soluble molecules, such as progesterone and estrogen, it"s important to explain that most
            of their "binding" to proteins or other oil-loving molecules is really the nearly passive consequence of the
            molecules" being forced away from the watery phase--they are hydrophobic, and although it would take a great
            amount of energy to make these insoluble substances enter the watery phase, the attractive force between
            them and the cell is usually small. This means that they can be freely mobile, while "bound" or concentrated
            within the cell. The oxygen atoms, and especially the phenolic group of estrogen, slightly reduce the
            hormones" affinity for simple oils, but they interact with other polar or aromatic groups, giving estrogen
            the ability to bind more strongly and specifically with some proteins and other molecules. Enzymes which
            catalyze estrogen"s oxidation-reduction actions are among the specific estrogen-binding proteins.
        </p>
        <p>
            Many proteins and lipoproteins bind steroids, but some intracellular proteins bind them so strongly that
            they have been--in a very teleological, if not anthropomorphic, way--considered as the switch by which the
            hormone turns on the cellular response. In the popular doctrine of the Estrogen Receptor, a few molecules of
            estrogen bind to the receptors, which carry them to the nucleus of the cell, where the activated receptors
            turn on the genes in charge of the female response. (Or the male response, or the growth response, or the
            atrophy response, or whatever genetic response estrogen is producing.) Once the switch has been thrown, the
            estrogen molecules have fulfilled their hormonal duty, and must get lost, so that the response isn"t
            perpetuated indefinitely by a few molecules.
        </p>
        <p>
            Although the Estrogen Receptor doctrine is worse than silly, there are real proteins which bind estrogen,
            and some of these are called receptors. The uterus, breast, and brain, which are very responsive to
            estrogen, bind, or concentrate, estrogen molecules.
        </p>
        <p>
            When I was working on my dissertation, I tried to extract estrogens from hamster uteri, but the chemical
            techniques I was using to measure estrogen weren"t accurate for such small quantities. A few years later, S.
            Batra was able to extract the estrogen from human tissue in quantities large enough for accurate analysis by
            radioimmunoassay. (Batra, 1976.)
        </p>
        <p>
            His crucial observation was that the difference in estrogen concentration between tissue and blood was
            lowest in the luteal phase, when progesterone is high:
        </p>
        <p>
            <strong>"The tissue/plasma ratio of E2 [estradiol] ranged from</strong>
            <strong>1.45 to 20.36 with very high values in early follicular phase and the lowest in mid-luteal
                phase."</strong> This means that progesterone prevents the tissue from concentrating estrogen. He made
            similar observations during pregnancy, <strong>
                with tissue estrogen decreasing as blood progesterone increased, so that</strong>
            <strong>there is less estrogen in the tissue than in the plasma.</strong>
            But in women who aren"t pregnant, and when their progesterone is low, the tissues may contain 20 to 30 times
            more estrogen than the plasma (in equal volumes).
        </p>
        <p>
            In aging, the sharply decreased progesterone production creates a situation resembling the follicular phase
            of the menstrual cycle, allowing tissues to concentrate estrogen even when the serum estrogen may be low.
        </p>
        <p>
            "<strong>In postmenopausal women, the tissue concentration of E2 was not significantly lower than in
                menstruating women in follicular phase. . . .</strong>" (Akerlund, et al., 1981.)
        </p>
        <p>
            Besides the relatively direct actions of progesterone on the estrogen receptors, keeping their concentration
            low, and its indirect action by preventing prolactin from stimulating the formation of estrogen receptors,
            there are many other processes that can increase or decrease the tissue concentration of estrogen, and many
            of these influences change with aging.
        </p>

        <p>
            There are two kinds of enzyme that produce estrogen. Aromatase converts male hormones into estrogen.
            Beta-glucuronidase converts the inactive estrogen-glucuronides into active estrogen. The healthy liver
            inactivates practically all the estrogen that reaches it, mostly by combining it with the "sugar acid,"
            glucuronic acid. This makes the estrogen water soluble, and it is quickly eliminated in the urine. But when
            it passes through inflamed tissue, these tissues contain large amounts of beta-glucuronidase, which will
            remove the glucuronic acid, leaving the pure estrogen to accumulate in the tissue.
        </p>
        <p>
            Many kinds of liver impairment decrease its ability to excrete estrogen, and estrogen contributes to a
            variety of liver diseases. The work of the Biskinds in the 1940s showed that a dietary protein deficiency
            prevented the liver from detoxifying estrogen. Hypothyroidism prevents the liver from attaching glucuronic
            acid to estrogen, and so increases the body"s retention of estrogen, which in turn impairs the thyroid
            gland"s ability to secrete thyroid hormone. Hypothyroidism often results from nutritional protein
            deficiency.
        </p>
        <p>
            Although we commonly think of the ovaries as the main source of estrogen, the enzyme which makes it can be
            found in all parts of the body. Surprisingly, in rhesus monkeys, aromatase in the arms accounts for a very
            large part of estrogen production. Fat and the skin are major sources of estrogen, especially in older
            people. <strong>The activity of aromatase increases with aging, and under the influence of prolactin,
                cortisol, prostaglandin, and the pituitary hormones, FSH (follicle stimulating hormone) and growth
                hormone.</strong>
            <strong>It is inhibited by progesterone, thyroid, aspirin, and high altitude.</strong>
            Aromatase can produce estrogen in fat cells, fibroblasts, smooth muscle cells, breast and uterine tissue,
            pancreas, liver, brain, bone, skin, etc. Its action in breast cancer, endometriosis, uterine cancer, lupus,
            gynecomastia, and many other diseases is especially important. Aromatase in mammary tissue appears to
            increase estrogen receptors and cause breast neoplasia, independently of ovarian estrogen (Tekmal, et al.,
            1999).
        </p>
        <p>
            Women who have had their ovaries removed are usually told that they need to take estrogen, but animal
            experiments consistently show that removal of the gonads causes the tissue aromatases to increase. The loss
            of progesterone and ovarian androgens is probably responsible for this generalized increase in the formation
            of estrogen. In the brain, aromatase increases under the influence of estrogen treatment.
        </p>

        <p>
            Sulfatase is another enzyme that releases estrogen in tissues, and its activity is inhibited by
            antiestrogenic hormones.
        </p>
        <p>
            In at least some tissues, progesterone inhibits the release or activation of beta-glucuronidase (which,
            according to Cristofalo and Kabakjian, 1975, increases with aging). Glucaric acid, which inhibits this
            enzyme, is being used to treat breast cancer, and glucuronic acid also tends to inhibit the intracellular
            release of estrogen by beta-glucuronidase.
        </p>
        <p>
            Although there is clearly a trend toward the rational use of antiestrogenic treatments for breast cancer, in
            other diseases the myth of estrogen deficiency still prevents even rudimentary approaches.
        </p>
        <p>
            Ever since Lipshutz" work in the 1940s, it has been established that the <strong><em>
                    uninterrupted</em></strong> effect of a little estrogen is more harmful than larger but intermittent
            exposures. But after menopause, when progesterone stops its cyclic displacement of estrogen from the
            tissues, the tissues retain large amounts of estrogen continuously.
        </p>
        <p>
            The menopause itself is produced by the prolonged exposure to estrogen beginning in puberty, in spite of the
            monthly protection of the progesterone produced by cycling ovaries. The unopposed action of the high
            concentration of tissue-bound estrogen after menopause must be even more harmful.
        </p>

        <p>
            The decline of the antiestrogenic factors in aging, combined with the increase of pro-estrogenic factors
            such as cortisol and prolactin and FSH, occurs in both men and women. During the reproductive years, women"s
            cyclic production of large amounts of progesterone probably retards their aging enough to account for their
            greater longevity. Childbearing also has a residual antiestrogenic effect and is associated with increased
            longevity.
        </p>
        <p>
            Being aware of this pervasive increase in estrogen exposure with aging should make it possible to marshal a
            comprehensive set of methods for opposing that trend toward degeneration.

            progesterone administration on progesterone and estrogen receptors in the uterus, vagina and urethra of
            rabbits was studied. After 24 h of<strong>
                progesterone treatment the concentration of cytosolic progesterone receptors decreased to about 25% of
                the control value in the uterus, whereas no significant change in receptor concentration was observed in
                the vagina or the urethra. The concentration of the nuclear progesterone receptor did not change in any
                of the three tissues studied. The apparent dissociation constant (Kd) of nuclear progesterone receptor
                increased after progesterone treatment in all</strong> three tissues. Although the Kd of the cytosolic
            progesterone receptor also increased in all tissues, the difference was significant for only the vagina
            and<strong>
                urethra. The concentration of cytosolic estrogen receptors in the uterus decreased significantly (P less
                than 0.001) after progesterone treatment whereas the Kd value increased slightly (P less than 0.05). In
                vagina or the urethra,</strong>

            there was no change in either estrogen receptor concentration or Kd values after progesterone treatment.
            These data clearly showed that the reduction by progesterone of progesterone and estrogen receptor
            concentrations occurs only in the uterus and not in the vagina or the urethra.

            Biol Reprod, 1993 Oct, 49:4, 647-52<strong>. Pathologic effect of estradiol on the hypothalamus.</strong>
            Brawer JR; Beaudet A; Desjardins GC; Schipper HM. Estradiol provides physiological signals to the brain
            throughout life that are indispensable for the development and regulation of reproductive function. In
            addition to its multiple physiological actions, we have shown that estradiol is also selectively cytotoxic
            to beta-endorphin neurons in the hypothalamic arcuate nucleus. The mechanism underlying this neurotoxic
            action appears to involve the conversion of estradiol to catechol estrogen and subsequent oxidation to
            o-semiquinone free radicals. The estradiol-induced loss of beta-endorphin neurons engenders a compensatory
            increment in mu opioid binding in the medial preoptic area rendering this region supersensitive to residual
            beta-endorphin or to other endogenous opioids. The consequent persistent opioid inhibition results in a
            cascade of neuroendocrine deficits that are ultimately expressed as a chronically attenuated plasma LH
            pattern to which the ovaries respond by becoming anovulatory and polycystic. This neurotoxic action of
            estradiol may contribute to a number of reproductive disorders in humans and in animals in which aberrant
            hypothalamic function is a major component.

                Vitamin E protects hypothalamic beta-endorphin neurons from estradiol neurotoxicity.</strong> Desjardins
            GC; Beaudet A; Schipper HM; Brawer JR. Estradiol valerate (EV) treatment has been shown to result in the
            destruction of 60% of beta-endorphin neurons in the hypothalamic arcuate nucleus. Evidence suggests that the
            mechanism of EV-induced neurotoxicity involves the conversion of estradiol to catechol estrogen and
            subsequent oxidation to free radicals in local peroxidase-positive astrocytes. In this study, we examined
            whether treatment with the antioxidant, vitamin E, protects beta-endorphin neurons from the neurotoxic
            action of estradiol. Our results demonstrate that chronic vitamin E treatment prevents the decrement in
            hypothalamic beta-endorphin concentrations resulting from arcuate beta-endorphin cell loss, suggesting that
            the latter is mediated by free radicals. Vitamin E treatment also prevented the onset of persistent vaginal
            cornification and polycystic ovarian condition which have been shown to result from the EV-induced
            hypothalamic pathology.

                Estrogen-induced hypothalamic beta-endorphin neuron loss: a possible model of hypothalamic

            Desjardins GC; Beaudet A; Meaney MJ; Brawer JR. Over the course of normal aging, all female mammals with
            regular cycles display an irreversible arrest of cyclicity at mid-life. Males, in contrast, exhibit
            gametogenesis until death.<strong>
                Although it is widely accepted that exposure to estradiol throughout life contributes to reproductive
                aging, a unified hypothesis of the role of estradiol in reproductive senescence has yet to
                emerge.</strong> Recent evidence derived from a rodent model of chronic estradiol-mediated accelerated
            reproductive senescence now suggests such a hypothesis. It has been shown that chronic estradiol exposure
            results in the <strong>destruction of greater than 60% of all beta-endorphin neurons in the arcuate nucleus
            </strong>
            while leaving other neuronal populations spared. This loss of opioid neurons is prevented by treatment with
            antioxidants indicating that it results from <strong>estradiol-induced formation of free radicals.
                Furthermore, we have shown that this beta-endorphin cell loss is followed by a compensatory upregulation
                of mu opioid receptors in the vicinity of LHRH cell bodies.</strong> The increment in mu opioid
            receptors presumably renders the opioid target cells supersensitive to either residual beta-endorphin or
            other endogenous mu ligands, such as met-enkephalin, thus resulting in chronic opioid <strong>suppression of
                the pattern of LHRH release, and subsequently that of LH.</strong> Indeed, prevention of the
            neuroendocrine effects of estradiol by antioxidant treatment also <strong>prevents the cascade of
                neuroendocrine aberrations resulting in anovulatory acyclicity.</strong> The loss of beta-endorphin
            neurons along with the paradoxical opioid supersensitivity which ensues, provides a unifying framework in
            which to interpret the diverse features that characterize the reproductively senescent female.

            Kauppila A, Jarvinen PA To evaluate the significance of progesterone and estradiol in human uterine activity
            during pregnancy and delivery the blood concentrations of these hormones were monitored weekly during the
            last trimester of pregnancy and at the onset of labour in 15 women, and before and 3 hours after the
            induction of term delivery in 83 parturients. Neither plasma concentrations of progesterone or estradiol nor
            the ratio of progesterone to estradiol changed significantly during the last trimester of pregnancy or at
            the onset of delivery. After the<strong>
                induction of delivery parturients with initial progesterone dominance (ratio of progesterone to
                estradiol higher than 5 before induction) demonstrated a significant fall in serum concentration of
                progesterone and in the ratio of progesterone to estradiol while estradiol concentration rose
                significantly. In estrogen dominant women (progesterone to estradiol ratio equal to or lower than 5) the
                serum concentration of progesterone and the ratio of progesterone to</strong> estradiol rose
            significantly during the 3 hours after the induction of delivery. Our results suggest that the peripheral
            blood levels of progesterone and estradiol do not correlate with the tissue biochemical changes which
            prepare the uterine cervix and myometrium for delivery. The observation that the ratio of progesterone to
            estradiol decreased in progesterone-dominant and increased in estrogen-dominant women stresses the
            importance of a well balanced equilibrium of these hormones for prostaglandin metabolism during human

            inactivation of the occupied form of nuclear Re as determined during a 30 min incubation of uterine nuclear
            extract in vitro at 36 degrees C. Since we previously demonstrated that such in vitro Re-inactivating

            Previous studies have indicated that serum levels of follicle-stimulating hormone rise with age during the

                premenopausal women aged 18 to 23 and 29 to 40 years. We found that increased age during reproductive
                life is accompanied by a significant rise in both basal and stimulated serum follicle-stimulating
                hormone levels. This was accompanied by an increase in the serum level of estradiol-17 beta and the

            </strong>
            levels of estradiol-17 beta and 17 beta-estradiol-17-glucosiduronate. The serum level of estrone sulfate
            decreased with age. Serum and urine levels of other estrogens were unchanged. The basal and stimulated
            levels of luteinizing hormone were also unchanged. There was a significant decrease in basal and stimulated
            serum prolactin levels. Serum levels of dehydroepiandrosterone and dehydroepiandrosterone sulfate decreased
            with age, but serum testosterone was unchanged. It is concluded that significant age-related changes in the
            female hormonal environment occur during the reproductive years.

                suitable tool for reproductive aging studies in the female rat.</strong> Rodriguez, P; Fernandez-Galaz,
            C; Tejero, A. "The present study was designed to determine whether the modification of exposure time to
            large doses of estrogens provided a reliable model for early changes in reproductive aging." "Premature
            occurrence of vaginal opening was observed in all three estrogenized groups independently of EB exposure.
            However, females bearing implants for 24 h had first estrus at the same age as their controls and cycled
            regularly, and neither histological nor gonadal alterations could be observed at 75 days. Interestingly,
            they failed to cycle regularly at 5 mo whereas controls continued to cycle." "On the other hand, the
            increase of EB exposure (Ei5, EI) resulted in a gradual and significant delay in the onset of first estrus
            and in a high number of estrous phases, as frequently observed during reproductive decline. At 75 days, the
            ovaries of these last two groups showed a reduced number of corpora lutea and <strong>an increased number of
                large follicles</strong>. According to this histological pattern, ovarian weight and progesterone (P)
            content gradually decreased whereas both groups showed higher estradiol (E-2) content than controls. This
            resulted in <strong>a higher E-2:P ratio, comparable to that observed in normal aging rats.</strong>
            <strong>The results allow us to conclude that the exposure time to large doses of estrogens is critical to
                the gradual enhancement of reproductive decline. Furthermore, exposures as brief as 24 h led to a
                potential early model for aging studies that will be useful to verify whether neuroendocrine changes

            Steroid sulfatase which hydrolyzes several sulfated steroids such as estrone sulfate, dehydroepiandrosterone
            sulfate, and cholesterol sulfate may be involved. In the present study, we therefore, assessed steroid
            sulfatase mRNA levels in breast malignancies and background tissues from 38 patients by reverse
            transcription and polymerase chain reaction. The levels in breast cancer tissues were significantly
            increased at 1458.4+/-2119.7 attomoles/mg RNA (mean +/- SD) as compared with 535.6+/-663.4 attomoles/mg RNA
            for non-malignant tissues (P&lt;0.001). Thus, increased steroid sulfatase expression may be partly
            responsible for local overproduction of estrogen and provide a growth advantage for tumor cells.

                tissues.</strong> Thijssen JH, van Landeghem AA, Poortman J In order to exert their biological effects,
            steroid hormones must enter the cells of target tissues and after binding to specific receptor molecules
            must remain for a prolonged period of time in the nucleus. Therefore the endogenous levels and the
            subcellular distribution of estradiol, estrone, DHEAS, DHEA ad 5-Adiol were measured in normal breast
            tissues and in malignant and nonmalignant breast tumors from pre- and postmenopausal women. For estradiol
            the highest tissue levels were found in the malignant samples<strong>. No differences were seen in these
                levels between pre- and postmenopausal women despite the largely different peripheral blood
                levels.</strong> For estrone no differences were found between the tissues studied. Although the
            estradiol concentration was higher in the estradiol-receptor-positive than in the receptor-negative tumors,
            no correlation was calculated between the estradiol and the receptor consent. Striking differences were seen
            between the breast and uterine tissues for the total tissue concentration of estradiol, the ratio between
            estradiol and estrone, and the subcellular distribution of both estrogens. <strong>At similar receptor
                concentrations in the tissues these differences cannot easily be explained.</strong> Regarding the
            androgens, the tissue/plasma gradient was higher for DHEA than for 5-Adiol, and for DHEAS there was very
            probably a much lower tissue gradient. The highly significant correlation between the androgens suggests an
            intracellular metabolism of DHEAS to DHEA and 5-Adiol. <strong>Lower concentrations of DHEAS and DHEA were
                observed in the malignant tissues compared with the normal ones and the benign lesions.</strong> For
            5-Adiol no differences were found and therefore these data do not support our original hypothesis on the
            role of this androgen in the etiology of breast abnormalities. Hence the way in which adrenal androgens
            express their influence on the breast cells remains unclear.

        <p>
            There always seems to be a rough balance between tissue regeneration and tissue degeneration, with growth
            and repair occurring when the equilibrium shifts in one direction,and with atrophy or degeneration occurring
            when the balance shifts in the other direction. If we can understand the mechanisms of atrophy, and how to
            retard or to block tissue destruction, then we can restore the balance to a degree which might allow
            regeneration to occur, even if we don't clearly understand the mechanisms of growth.
        </p>

            Skin and bones are such different types of tissue that it will be useful to start with them, because if we
            can see similar processes of degeneration or regeneration in them, then the chances are good that the same
            processes will occur in other tissues too. Bone is a relatively stable tissue, while skin is a tissue whose
            cells divide rapidly.

            It is common medical knowledge that cortisone and realted glucocorticioid-type hormones cause skin to
            atrophy, becoming thinner. Using topical applications of a synthetic derivative of cortisione,CM Papa and A
            M. Kligman showed that the atrophy extended to the pigment cells,reducing theirr size and eliminating most
            of their dendritic branches. Some animal studies have found that estrogen caused the skin to become thinner.
            The other steroids they tested,progesterone, testosterone,and pregnenolone, acted in the opposite direction,
            making aged and atrophied skin thicker and more regular. They also made the pigment cells larger, and
            increased their branchinhg.l Since these hormones were already known to have protective actions against
            cortisone and estrogen, these results were not too surprising, though they did directly contradict the
            claims of people who made estrogen-containing cosmetics.
        </p>
        <p>
            Since progesterone and pregnenolone do not cause healthy, young skin to thicken, their effect in damaged
            skin is probably partly to replace the deficiency of that type of steroid which occurs with aging, and to
            offset the damaging effects of the catabolic hormones, whose influence does not decrease with age.

            Many years ago it was found that in old age a woman's estrogens were increasedd relative to the 17-keto
            steroids adrenal androgens. Later, it was found that the conversion of androgen to estrogen increases with
            age in both men and women, and that this occurs largely in fat cells. Several years ago, P. K. Siiteri found
            that low thyroid modified the enzymes of fat cells in a way that would tend to increase the conversion of
            androgen to estrogen. More recently, it was found that adding progesterone to the enzymes had the opposite
            effect of aging and hypothyroidism, protecting the androgen from conversion to estrogen. These researchers
            (C. J. Newton and colleagues, of London) concluded that the decreased output of progesterone after the
            menopause might account for the increased production of estrogen.3 Since progesterone declines in aging men,
            too, this could account for the same process in men.

            Vitamin A's effect on the skin opposes that of estrogen.4 There are several mechanisms that could account
            for this. Vitamin A is used in the formation of steroids, and since the skin is a major site of steroid
            metabolism, vitamin A might help to maintain the level of the anti-catabolic steroids. A deficiency of
            vitamin A causes excessive release of the lysosomal enzymes, acid hydrolases, resulting in tissue
            catabolism.5 Also, vitamin A is necessary for the proper differentiation of cells in skin and other
            membranes. A deficiency tends to cause an increased rate of cell division, with the production of abnormal
            cells, and a substitution of keratinized cells for other types. Estrogen also promotes keratinization and
            speeds cell division. A deficiency of vitamin A can cause leukoplakia in the mouth and on the cervix of the
            uterus; although this is considered "pre-cancerous," I have found it to be very easily reversible, as I have
            discussed elsewhere.6 I suspect that the intracellular fiber, keratin, is produced when a cell can't afford
            to do anything more complex. Adequate vitamin A speeds protein synthesis,7 and allows it to be used more
            efficiently.

            Prolactin (which is promoted by estrogen, and inhibited by progesterone) increases with stress and with age.
            It probably affects every tissue, but it seems to have its greatest efects on the secretory membranes. It is
            known to have strong effects on the kidney, gut and skin (sweat and oil glands, hair follicles, and feathers
            inbirds), and on the gills of fish. Its involvement with milk production suggests that it might mobilize
            calcium from bones, and inf fact it does contribute to osteoporosis. This was foreseen by G. Bourne, in his
            book on the metabolism of hard tissues, when he suggested that estrogen, acting through the pituitary, might
            be expected to promote osteoporosis.

            the house fall far enough to break some facial bones. During his recovery, he developed arthritis in his
            hands. It is fairly common for arthritis to appear shortly after an accident, a shock, or surgery, and Han
            Selye's famous work with rats shows that when stress exhausts the adrenal glands (so they are unable to
            produce normal amounts of cortisone and related steroid hormones), arthritis and other "degenerative"
            diseases are likely to develop.
        </p>
        <p>
            But when this man went to his doctor to "get something for his arthritis," he was annoyed that the doctor
            insisted on giving him a complete physical exam, and wouldn't give him a shot of cortisone. The examination
            showed low thyroid function, and the doctor prescribed a supplement of thyroid extract, explaining that
            arthritis is one of the many symptoms of hypothyroidism. The patient agreed to take the thyroid, but for
            several days he grumbled about the doctor 'fixing something that wasn't wrong' with him, and ignoring his
            arthritis. But in less than two weeks, the arthritis had entirely disappeared. He lived to be 89, without a
            recurrence of arthritis. (He died iatrogenically, while in good health.)
        </p>
        <p>
            Selye's work with the diseases of stress, and the anti-stress hormones of the adrenal cortex, helped many
            scientists to think more clearly about the interaction of the organism with its environment, but it has led
            others to focus too narrowly on hormones of the adrenal cortex (such as cortisol and cortisone), and to
            forget the older knowledge about natural resistance. There are probably only a few physicians now practicing
            who would remember to check for hypothyroidism in an arthritis patient, or in other stress-related
            conditions. Hypothyroidism is a common cause of adrenal insufficiency, but it also has some direct effects
            on joint tissues. In chronic hypothyroidism (myxedema and cretinism), knees and elbows are often bent
            abnormally.
        </p>
        <p>
            By the 1930's, it was well established that the resistance of the organism depended on the energy produced
            by respiration under the influence of the thyroid gland, as well as on the adrenal hormones, and that the
            hormones of pregnancy (especially progesterone) could substitute for the adrenal hormones. In a sense, the
            thyroid hormone is the basic anti-stress hormone, since it is required for the production of the adrenal and
            pregnancy hormones.
        </p>

        <p>
            A contemporary researcher, F. Z. Meerson, is putting together a picture of the biological processes involved
            in adapting to stress, including energy production, nutrition, hormones, and changes in cell structure.
        </p>
        <p>
            While one of Selye's earliest observations related gastrointestinal bleeding to stress, Meerson's work has
            revealed in a detailed way how the usually beneficial hormone of adaptation, cortisone, can cause so many
            other harmful effects when its action is too prolonged or too intense.
        </p>
        <p>
            Some of the harmful effects of the cortisone class of drugs (other than gastro-intestinal bleeding) are:
            Hypertension, osteoporosis, delayed healing, atrophy of the skin, convulsions, cataracts, glaucoma,
            protruding eyes, psychic derangements, menstrual irregularities, and loss of immunity allowing infections
            (or cancer) to spread.
        </p>
        <p>
            While normal thyroid function is required for the secretion of the adrenal hormones, the basic signal which
            causes cortisone to be formed is a drop in the blood glucose level. The increased energy requirement of any
            stress tends to cause the blood sugar to fall slightly, but hypothyroidism itself tends to depress blood
            sugar.
        </p>

        <p>
            The person with low thyroid function is more likely than a normal person to require cortisone to cope with a
            certain amount of stress. However, if large amounts of cortisone are produced for a long time, the toxic
            effects of the hormone begin to appear. According to Meerson, heart attacks are provoked and aggravated by
            the cortisone produced during stress. (Meerson and his colleagues have demonstrated that the progress of a
            heart attack can be halted by a treatment including natural substances such as vitamin E and magnesium.)
        </p>
        <p>
            While hypothyroidism makes the body require more cortisone to sustain blood sugar and energy production, it
            also limits the ability to produce cortisone, so in some cases stress produces symptoms resulting from a
            deficiency of cortisone, including various forms of arthritis and more generalized types of chronic
            inflammation.
        </p>
        <p>
            Often, a small physiological dose of natural hydrocortisone can help the patient meet the stress, without
            causing harmful side-effects. While treating the symptoms with cortisone for a short time, it is important
            to try to learn the basic cause of the problem, by checking for hypothyroidism, vitamin A deficiency,
            protein deficiency, a lack of sunlight, etc. (I suspect that light on the skin directly increases the skin's
            production of steroids, without depending on other organs. Different steroids probably involve different
            frequencies of light, but orange and red light seem to be important frequencies.) Using cortisone in this
            way, physiologically rather than pharmacologically, it is not likely to cause the serious problems mentioned
            above.
        </p>
        <p>
            Stress-induced cortisone deficiency is thought to be a factor in a great variety of unpleasant conditions,
            from allergies to ulcerative colitis, and in many forms of arthritis. The stress which can cause a cortisone
            deficiency is even more likely to disturb formation of progesterone and thyroid hormone, so the fact that
            cortisone can relieve symptoms does not mean that it has corrected the problem.
        </p>
        <p>
            According to the Physicians' Desk Referenc, hormones similar to cortisone are useful for treating rheumatoid
            arthritis, post-traumatic osteoarthritis, synovitis of osteoarthritis, acute gouty arthritis, acute
            nonspecific tenosynovitis, psoriatic arthritis, ankylosing spondylitis, acute and subacute bursitis, and
            epicondylitis.
        </p>

        <p>
            Although cortisone supplementation can help in a great variety of stress-related diseases, no curewill take
            place unless the basic cause is discovered. Besides the thyroid, the other class of adaptive hormones which
            are often out of balance in the diseases of stress, is the group of hormones produced mainly by the gonads:
            the "reproductive hormones." During pregnancy these hormones serve to protect the developing baby from the
            stresses suffered by the mother, but the same hormones function as part to the protective anti-stress system
            in the non-pregnant individual, though at a lower level.
        </p>
        <p>
            Some forms of arthritis are known to improve or even to disappear during pregnancy. As mentioned above, the
            hormones of pregnancy can make up for a lack of adrenal cortex hormones. During a healthy pregnancy, many
            hormones are present in increased amounts, including the thyroid hormones. Progesterone, which is the most
            abundant hormone of pregnancy, has both anti-inflammatory and anesthetic actions, which would be of obvious
            benefit in arthritis.
        </p>
        <p>
            There are other naturally anesthetic hormones which are increased during pregnancy, including DHEA, which is
            being studied for its anti-aging, anti-cancer, and anti-obesity effects. (One of the reasons that is
            frequently given for the fact that this hormone hasn't been studied more widely is that, as a natural
            substance, it has not been monopolized by a drug patent, and so no drug company has been willing to invest
            money in studying its medical uses.) These hormones also have the ability to control cell division, which
            would be important in forms of arthritis that involve invasive tissue growth.
        </p>
        <p>
            While these substances, so abundant in pregnancy, have the ability to substitute for cortisone, they can
            also be used by the adrenal glands to produce cortisol and related hormones. But probably the most
            surprising property of these natural steroids is that they protect against the toxic side-effects of
            excessive adrenal hormones. And they seem to have no side-effects of their own; after about fifty years of
            medical use, no toxic side effects have been found for progesterone or pregnenolone.
        </p>
        <p>
            Pregnenolone is the material the body uses to form either progesterone or DHEA. Others, including DHEA,
            haven't been studied for so long, but the high levels which are normally present in healthy people would
            suggest that replacement doses, to restore those normal levels, would not be likely to produce toxic side
            effects. And, considering the terrible side effects of the drugs that are now widely used, these drugs would
            be justifiable simply to prevent some of the toxic effects of conventional treatment.
        </p>
        <p>
            It takes a new way of thinking to understand that these protective substances protect against an excess of
            the adrenal steroids, as well as making up for a deficiency. Several of these natural hormones also have a
            protective action against various poisons; Selye called this their "catatoxic" effect.
        </p>
        <p>
            Besides many people whose arthritis improved with only thyroid supplementation, I have seen 30 people use
            one or more of these other natural hormones for various types of arthritis, usually with a topical
            application. Often the pain is relieved within a few minutes. I know of several other people who used
            progesterone topically for inflamed tendons, damaged cartilage, or other inflammations. Only one of these, a
            woman with rheumatoid arthritis in many joints, had no significant improvement. An hour after she had
            applied it to her hands and feet, she enthusiastically reported that her ankle had stopped hurting, but
            after this she said she had no noticeable improvement.
        </p>
        <p>
            We often hear that "there is no cure for arthritis, because the causes are not known." If the cause is an
            imbalance in the normal hormones of adaptation and resistance, then eliminating the cause by restoring
            balance will produce a true cure. But if it is more profitable to sell powerful drugs than to sell the
            nutrients needed to form natural hormones (or to supplement those natural hormones) we can't expect the drug
            companies to spend any money investigating that sort of cure. And at present the arthritis market amounts to
            billions of dollars in drug sales each year.

            The transparency of life: Cataracts as a model of age-related disease
        </h1>

        <em><p>
                Cataracts can disappear when the eye's metabolic condition is corrected. A supply of energy is essential
                to maintain the transparent structure.
            </p>

            <p>
                Lactic acid increases as carbon dioxide decreases, during a typical energy deficiency. Deficient
                thyroid, and the resulting excess of cortisol relative to pregnenolone and progesterone, define the
                energy deficiency.
            </p>
            <p>
                Increased lactate relative to CO2 in the cell alters cell pH and electrical charge, causing swelling.
                Swelling and increased water content characterize the cataract.
            </p>
            <p>
                High altitude is inversely related to cataracts, despite the known role of sunlight in causing
                cataracts; this is a strong confirmation of the protective role of carbon dioxide.

            In the markets around Lake Patzcuaro, they sell green transparent fish, about 6 inches long. When cooked,
            the meat is white, like ordinary fish. Most fish filets are a little translucent, but are at least cloudy,
            and usually pink by transmitted light. I don"t know how the transparent fish work, because it seems that the
            blood and the network of blood vessels needed to sustain muscle activity would diffuse the light. Anyway,
            cooking disrupts the mysteriously ordered state of water and proteins that makes them transparent, roughly
            the way egg-white loses its transparency when it is cooked. I have never heard a convincing explanation for
            the opacity of cooked egg-white, either, but anything that disrupts the original structuring of the
            protein-water interaction will destroy the transparency.
        </p>
        <p>
            Around 1970, I used a technique called nuclear magnetic resonance (NMR), which is the basis for the
            procedure known as MRI (magnetic resonance imaging), to compare the state of water in old (uterine) tissue
            and young tissue. Old tissue predictably contains less water than young tissue, but I found that the water
            in the old tissue was in a relatively free and uncontrolled state. When tissue swells and takes up water,
            more of the water is likely to be in this uncontrolled state, and this is one of the things that makes MRI
            so useful, because tumors, for example, show up vividly because of their large amount of uncontrolled
            ("unbound") water. I suspect that the measurements I made on uterine tissue showed a localized effect, that
            opposed the general trend toward increased dryness with aging. In the case of cataracts, this is clearly the
            case<strong>: </strong> Most of the lens becomes drier with age, but at a certain point there is a reversal,
            and some of the tissue takes up too much water. That"s why I refer to cataracts as a model of age-related
            disease, rather than as a model of aging. In this sense, I am including them among the inflammatory diseases
            of aging--colitis, arthritis, and cancer, for example. MRI now can show developing cataracts before they are
            visible, because of increased water content in the area.
        </p>
        <p>
            The lens of the eye is a fairly dense, tough, transparent living structure, which can develop opaque areas,
            cataracts, as a result of old age, poisoning, radiation, disease, or trauma. The varieties of cataract
            relate to the causes. Most of the oxidative metabolism of the lens is in or near the epithelial layer that
            surrounds it. Old-age cataracts most often begin in this region.
        </p>
        <p>
            Although the efficient oxidative energy metabolism occurs near the surface of the lens, <strong>there is a
                constant flow of fluid through the lens,</strong>
            entering it mainly in the front and back, and leaving on its "sides" or equator (considering the front and
            back as the poles, the direction light passes through). Oxygen and nutrients are supplied to the lens by way
            of this circulation of fluid, entering mostly from the aqueous humor in front (which also supplies the
            cornea), but also from the vitreous humor behind the lens.
        </p>

        <p>
            When the flow of nutrients and energy is impaired, the organized state of the protein and water system in
            the cell is damaged, and an excess of water is taken up by the cells, as the protein content decreases. The
            loss of organization causes light to be dispersed, with a loss of transparency.
        </p>
        <p>
            The lens of the eye is usually treated as something so specialized that it is hardly considered to be part
            of our living substance, just as dentistry has tended to treat teeth as inert things to be approached
            mechanically, rather than physiologically. <strong>The lens"s circulatory system is very interesting,
                because of what it says about the nature of living substance. In the absence of blood vessels, it
                provides its own flow of nutrients.</strong> This flow is reminiscent of the flow of substances through
            the dentine channels of the teeth, through the axons of nerves (two-way transport in a very narrow channel),
            and, in some ways recalls the flow of fluids in plants, called "guttation" (drop formation), which is
            disturbing to botanists, because it is contrary to the textbook descriptions of proper physiology.
        </p>
        <p>
            <strong>The flow of material through lens cells, dentine canals, and nerve axons should allow us to gain a
                perspective in which these observable processes become a model for other biological situations</strong>
            in which "transport" occurs<strong>:</strong> Kidney, intestine, or the skin of frogs, for example, in which
            water, ions, and other solutes are moved in considerable quantities.
        </p>

        <p>
            When cells metabolize, they create gradients. In the cell, electrical, chemical, osmotic, and thermal
            gradients, for example, are constantly being produced or maintained. The whole substance of the cell is
            involved in its life processes. Because of prejudices introduced 200 years ago, the life of the cell has
            been relegated to its "membrane" (where hypothetical "membrane pumps" reside) and its nucleus. <strong>
                When the term "cell" (hollow space) came into use instead of "corpuscle" (little body), a mind-set came
                into existence that discounted the importance of most of the living material,</strong> and claimed that
            it was a mere "random solution." Random solutions don"t do much. The wonderful "membrane," under the
            direction of the nucleus (and its set of instructions), took care of everything.
        </p>
        <p>
            Whenever assimilation or excretion took place, it was explained by inventing a property possessed by the
            cell "membranes." Therefore, we have physiology textbooks that have an unfounded explanation for everything.
            Before Copernicus, planetary movements were described as arbitrary "epicycles." They didn't make sense, but
            people studied them and felt that they were important. "Membrane physiology" is the modern equivalent of the
            Ptolemaic epicycles.
        </p>

        <p>
            We know that glucose can be metabolized into pyruvic acid, which, in the presence of oxygen, can be
            metabolized into carbon dioxide. Without oxygen, pyruvic acid can be converted into lactic acid. The
            production of lactic acid tends to increase the pH inside the cell, and its excretion can lower the pH
            outside the cell.
        </p>
        <p>
            The decrease of carbon dioxide that generally accompanies increased lactic acid, corresponds to increased
            intracellular pH. Carbon dioxide binds to many types of protein, for example by forming carbamino groups,
            changing the protein conformation, as well as its electrical properties, such as its isoelectric point. With
            increased pH, cell proteins become more strongly ionized, tending to separate, allowing water to enter the
            spaces, in the same way a gel swells in an alkaline solution.
        </p>
        <p>
            The Bohr-Haldane effect describes the fact that hemoglobin releases oxygen in the presence of carbon
            dioxide, and releases carbon dioxide in the presence of oxygen. When oxygen is too abundant, it makes
            breathing more difficult, and one of its effects is to cause carbon dioxide to be lost rapidly. At high
            altitude, more carbon dioxide is retained, and this makes cellular respiration more efficient.
        </p>
        <p>
            The importance of carbon dioxide to cell control process, and to the structure of the cell and the structure
            of proteins in general suggested that degenerative diseases would be less common at high altitude. Wounds
            and broken bones heal faster at high altitude, but the available statistics are especially impressive in two
            of the major degenerative conditions, cancer and cataracts.
        </p>
        <p></p>
        <p>
            The two biggest studies of altitude and cataracts (involving 12,217 patients in one study, and 30,565
            lifelong residents in a national survey in Nepal) showed a negative correlation between altitude and the
            incidence of cataract. At high altitude, cataracts appeared at a later age. <strong>In Nepal, an increase of
                a few thousand feet in elevation decreased the incidence of cataracts by 2.7 times. At the same time, it
                was found that exposure to sunlight increased the incidence of cataracts, and since the intensity of
                ultraviolet radiation is increased with altitude, this makes the decreased incidence of cataracts even
                more important.</strong>
        </p>

        <p>
            All of the typical causes of cataracts, aging, poisons, and radiation, decrease the formation of carbon
            dioxide, and tend to increase the formation of lactic acid.<strong>
                Lactic acid excess is typically found in eyes with cataracts.</strong>
        </p>
        <p>
            The electrical charge on the structural proteins will tend to increase in the presence of lactic acid or the
            deficiency of carbon dioxide, and the increase of charge will tend to increase the absorption of water.
        </p>
        <p>
            The lens can survive for a considerable length of time <em>in vitro </em>
            (since it has its own circulatory system),<em> </em>
            so it has been possible to demonstrate that changes in the composition of the fluid can cause opacities to
            form, or to disappear.
        </p>

        <p>
            Oxidants, including hydrogen peroxide which occurs naturally in the aqueous humor, can cause opacities to
            form quickly, but they will also disappear quickly in a solution that restores metabolic energy. The lens
            regulates itself powerfully<strong>;</strong> for example, it will swell when put into a hypotonic solution,
            but will quickly adapt, returning to approximately its normal size.
        </p>
        <p>
            Several years ago, I saw what appeared to be oxidant-induced cataracts. Two women had a very sudden onset of
            cataracts, and I asked about their diet and supplements<strong>;</strong> it turned out that one of them had
            begun taking 500 mg of zinc daily a few months earlier, and the other had begun taking 600 mg of zinc and
            250 mg of iron, on her doctor"s recommendation, just a couple of months before the cataracts appeared.

        <p>
            For some reason, there have been many nutritional supplements sold as cataract remedies in the form of eye
            drops. I suppose a trace of the material could diffuse through the cornea into the aqueous humor, where it
            might make a difference in the lens"s nutrient supply, but it seems more reasonable to treat the body as a
            whole, nourishing every part in a balanced way.

            Besides living at a high elevation or breathing extra carbon dioxide, the most certain way to increase the
            amount of carbon dioxide in the eye, and to prevent an excess of lactic acid, is to make sure that your
            thyroid function is adequate.
        </p>

        <p>
            One man who took thyroid, USP, and vitamin E told me that his cataracts had regressed, but I haven"t known
            other people who tried this.
        </p>
        <p>
            If a person already has distinct cataracts, it might be worthwhile to experiment with a relatively high
            degree of hypercapnia, for example, breathing a 5% mixture of CO2 in air.
        </p>
        <p>
            Carbon dioxide, at higher levels than are normal at sea level, has a profound effect on free radicals,
            reducing the free radical activity in the blood to approximately zero, before reaching the level that
            produces acidosis.
        </p>
        <p>
            There are several situations in which carbon dioxide affects the hydration, water content, of biological
            materials, that I think give an insight into its effects on the lens. Hydrophilic glycoproteins are involved
            in each case. These are proteins with attached chains of sugar molecules that make them associate with a
            large amount of water. In the cornea, increased carbon dioxide strongly protects against swelling. The bulk
            of the cornea is a connective tissue that is relatively simple and passive compared to the compact cellular
            structure of the lens, and it is conventional to describe the thin layers of cells on the inside and outside
            of the cornea as being responsible for the water content of the underlying substance. However, even when the
            epithelial cells are removed, it has been demonstrated that carbon dioxide is able to prevent corneal
            swelling. (M.V. Riley, et al., "The roles of bicarbonate and CO2 in transendothelial fluid movement and
            control of corneal thickness," <em>
                Invest. Ophthalmol. Vis. Sci. 36(1),</em> 103-112, 1995.)
        </p>

        <p>
            Bronchial mucous secretions are an even simpler system, so it is very interesting that carbon dioxide is
            recognized as the most powerful regulator of their behavior. (This has important implications for "cystic
            fibrosis," or mucoviscidosis.) Goodman and Gilman (page 1068, <em>
                Pharmacological Basis of Therapeutics,</em> 2nd Edition, Macmillan Co., 1956), say
        </p>
        <p>
            "Among inhalants, steam and carbon dioxide have been found to be excellent expectorants. Relative humidity
            above 85 per cent liquefies sputum, decreases its viscosity...." "Carbon dioxide is the most effective agent
            of all. It not only lowers the viscosity of tenacious sputum, thereby facilitating expectoration, but it
            decreases the volume of sputum by promoting its active resorption by bronchial mucosa." "A five to ten per
            cent concentration of carbon dioxide is adequate and well tolerated if administered at intervals." "Oxygen
            has been shown to be an antiexpectorant and has effects opposite to those of carbon"
        </p>
        <p>
            Oxygen tends to displace carbon dioxide from tissue, and is a source of free radicals.
        </p>
        <p>
            One of the best-known free radical scavenging substances that has been widely used as a drug is iodide. It
            has been used to treat asthma, parasites, syphilis, cancer, Graves" disease, periodontal disease, and
            arteriosclerosis. Diseases that produce tissue overgrowth associated with inflammation--granulomas--have
            been treated with iodides, and although the iodide doesn"t necessarily kill the germ, it does help to break
            down and remove the granuloma. Leprosy and syphilis were among the diseases involving granulomas* that were
            treated in this way. In the case of tuberculosis, it has been suggested that iodides combine with
            unsaturated fatty acids which inhibit proteolytic enzymes, and thus allow for the removal of the abnormal
            tissue.
        </p>
        <p>
            In experimental animals, iodide clearly delays the appearance of cataracts. (Buchberger, et al., 199l.)
        </p>
        <p>
            Inflammation, edema, and free radical production are closely linked, and are produced by most things that
            interfere with energy production.
        </p>
        <p>
            Endotoxin, produced by bacteria, mainly in the intestine, disrupts energy production, and promotes
            maladaptive inflammation. The wide spectrum of benefit that iodide has, especially in diseases with an
            inflammatory component, suggests first that it protects tissue by blocking free radical damage, but it also
            suggests the possibility that it might specifically protect against endotoxin.

        <p>
            There are subtler differences in transparence that probably have a variety of causes, but differences in
            water content or hydration might be involved in the lower transparency that has been seen in women's lenses.
            Estrogen, which tends to produce edema and hypotonic body fluids, also increases prolactin production.
            Prolactin is involved in water and electrolyte regulation, and it has been found to <strong>accelerate the
                development of experimental cataracts.</strong> (M. C. Ng, et al, 1987.) These hormones are associated
            with the calcification of soft tissues, and cataracts contain very high levels of calcium. (Avarachan and
            Rawal, 1987; Hightower and Reddy, 1982.)
        </p>
        <p>
            Estrogen is strongly associated with free radical processes, calcium mobilization, and acetylcholine
            release, all of which are involved in the process of excitoxicity. Alvarez, et al., (1996) have shown a
            possible involvement of acetylcholine in calcium mobilization in the lens.
        </p>
        <p>
            Serotonin is another regulatory substance strongly associated with prolactin and estrogen, and it also can
            be involved in disrupting the metabolism of the lens. This is one of the potential dangers in using
            supplemental tryptophan. (Candia, et al., 1980.)
        </p>
        <p>
            Old age commonly involves some changes in the color of tissues--loss of pigment from hair and skin, with
            appearance of new pigment (age pigment, lipofuscin), which may appear as "liver spots." But there is also a
            tendency of the toenails, fingernails, teeth, and lenses to turn yellow or brown. Some of this dark material
            seems to be age pigment, derived from unsaturated fatty acids, but other components have been identified,
            for example, tryptophan from damaged proteins. The Maillard reaction (similar to the browning that occurs in
            bread crust) has often been mentioned in relation to aging, and involves the combination of protein amino
            groups with sugars. But the browning of the lens tends to be associated with the general age related drying
            of the lens, it isn"t irregularly distributed, and it doesn"t significantly harm vision.
        </p>

        <p>
            When I first heard about the age-related browning of the lens, I thought that the experience of colors would
            be affected, so I devised a test in which the relative darkness of blue and yellow could be judged in
            comparison with a graded strip of shades of grey.
        </p>
        <p>
            After people of ages ranging from 10 to 80 had given exactly the same matches, I realized that the nervous
            system probably corrects for the "yellow filter" effect of the brown lens.
        </p>
        <p>
            The browning of tissues will be the subject of another newsletter.

            Among the interesting causes of cataracts<strong>: </strong>
            Tamoxifen and hypotonic fluids, sodium deficiency<strong>;</strong> toxicity of tryptophan<strong>;</strong>
            oxidants (metals, hydrogen peroxide, PUFA); diabetes, photosensitizers and sunlight<strong>; </strong>

            excess calcium, deficient magnesium. Excess cortisol. Radiation. Arachidonic and linoleic acids in other
            situations have been found to block cells' regulation of their water content. Hypothyroidism tends to
            increase the activity of serotonin, estrogen, prolactin, calcium, and the tendency of tissues to retain
            water, and to decrease the level of ATP.
        </p>
        <p>
            Among the factors that probably have a role in preventing cataracts<strong>: </strong>
            Thyroid, progesterone, pregnenolone, vitamin E, iodide, pyruvate. Increasing the carbon dioxide lowers the
            cell"s pH, and tends to resist swelling. Palmitic acid (a saturated fat that can be synthesized by our
            tissues) is normally oxidized by the lens. Calcium blockers experimentally prevent cataracts, suggesting
            that magnesium and thyroid (which also act to exclude calcium from cells) would have the same effect.
        </p>
        <p>
            Thyroid hormone is essential for maintaining adequate carbon dioxide production, for minimizing lactic acid,
            cortisol and prolactin, for regulating calcium and magnesium, for avoiding hypotonicity of the body fluids,
            and for improving the ratio of palmitic acid to linoleic acid.

            Candia OA; Lanzetta PA; Alvarez LJ; Gaines W, Biochim Biophys Acta (602)2, 389-400, 1980. "Tryptamine,
            5-methyltryptamine and 5-methoxytryptamine had dual effects: 1 mM in the posterior bathing solution
            depressed the potential difference of the posterior face of the lens, which resulted in an increase in the
            translenticular potential difference and short-circuit current; 1 mM in the anterior solution (in contact
            with the lens epithelium) produced a quick and pronounced reduction of the potential difference of the
            anterior face. This resulted in a 90-100% decline of the translenticular short-circuit current. Serotonin
            and tryptamine were then tested for their effect on the ATPases of lens epithelium. Both amines inhibited
            the enzymes with tryptamine at 5 mM completely inhibiting all ATPase activity. <strong>Since tryptophan is
                transported from the aqueous humor into the lens and may be converted by lens enzymes to serotonin and

            concentrations of 10-1000 microM, produces two major changes in the current-voltage relationships associated
            with the equatorial potassium current of the lens. First, the resting and reversal potentials become more
            negative than they were prior to treatment with hydrogen peroxide and second, the membrane resistance
            related to the equatorial current is decreased. The shift in the resting and reversal potentials is in the
            opposite direction from that produced by ouabain. Based on the Nernst equation, the shift in the reversal
            potential suggests that there is an <strong>increase in the concentration of potassium in the lens. The 86Rb
                uptake and efflux are increased. These observations suggest that hydrogen peroxide stimulates the
                Na,K-pump. The decrease in membrane resistance is inhibited by 100 microM of quinine, a
                calcium-dependent potassium channel blocker, and does not decrease in a calcium-free medium. This
                suggests that the decrease in resistance may be secondary to an increase in lenticular calcium.</strong>

            impermeant sulfhydryl binding agent,<strong>

            lens hydration has been shown to be a common phenomenon in most, if not all types of cataracts, we have been
            interested in investigating a possible role of prolactin in sugar cataract induction and progression. For
            this study, we have used morphological and biochemical approaches. The prolactin delivery method involved
            intraperitoneal implantation of one or more pellets in Sprague-Dawley female rats. Following implantation of
            the desired number of prolactin or control (nonprolactin) pellets, animals were either fed galactose and lab
            chow, or lab chow diet. Gross morphological observations of whole lenses, slit-lamp examination of lenses
            and light microscopic analysis of lens sections showed that in the galactose-fed prolactin group, galactose
            associated alteration progressed faster and total opacification (mature cataract development) was achieved
            earlier than in the nonprolactin group. The levels of galactose and dulcitol were higher in the lenses of
            galactose-fed prolactin treated rats as compared to lenses from nonprolactin (control) rats. No significant
            difference in lens Na+-K+ ATPase activity between the prolactin and nonprolactin group was observed. Our

            agents that <strong>coincide with those that catalyze oxidative damage to lipids.
            </strong>One of the consequences of lipid peroxidation is that the affected membrane is rendered more
            permeable to protons. A proton leak in the tight epithelium of lens <strong>would uncouple the
                Na+/K(+)-ATPases that regulate the water</strong> and ionic content of the bounded tissue. Once
            regulatory control of the osmotic pressure is lost, <strong>
                the phase state of the</strong> cell's soluble proteins would change, <strong>
                leading to refractive changes or, in extreme cases, precipitation</strong>. The same does not occur in
            cornea because the stroma is an extracellular polymer blend rather than solution of soluble polymers.
            Polymeric phase transitions in the cornea require that divalent cations pass the epithelial membrane, which
            can occur only through the action of ionophores.

            81:4, 319-23." "Of 220 children of both sexes below 12 years of age, with congenital or infantile cataract
            treated in Sankara Nethralaya, Madras, India, during a period of 2 years, 145 excreted fragments of GAG
            (heparan and chondroitin sulphates) in their urine. There was no such excretion among the control group of
            50 children. <strong>
                The same was found accumulated in the blood and lenses of affected children.</strong>
            In addition, xylose was present in small amounts in the urine and blood and xylitol was present in the lens.
            There was a significant elevation in the <strong>activity of beta glucuronidase in lymphocytes and
                urine,</strong>
            when compared with normals. All the above findings suggest deranged proteoglycan metabolism. As the urine
            contained mostly GAG fragments and very little xylose, Benedict's reagent was not reduced. This ruled out
            galactosaemia.CONCLUSION: An increase of <strong>beta glucuronidase activity might have caused extensive
                fragmentation of GAG</strong> with resultant accumulation in the blood and lens and excretion in urine.
            Small amounts of xylose may have come from xylose links between GAG and core protein of proteoglycans. Owing
            to their polyanionic nature, GAG fragments in the lens might abstract sodium, and with it water, thereby
            increasing the hydration of the lens. Excessive hydration and the osmotic effect of xylitol from xylose
            might cause cataract. While corneal clouding has been reported in inborn acid mucopolysaccharidosis,
            congenital or infantile cataract with deranged metabolism of proteoglycans (acid
            mucopolysaccharide-xylose-protein complex) is reported in children for the first time."

            insolubilization of lens proteins in the inducement of selenite cataract. The impact of selenite on the SH
            containing ATPase anzymes could be the cause of impairment in energy metabolism, derangement of electrolytes
            and osmotic imbalance which, in turn, accelerate the cortical involvement of lens opacities."

            Invest Ophthalmol Vis Sci, 1994 Mar, 35:3, 846-50 "PURPOSE. Studies have shown that stromal acidosis reduces
            the rate of corneal thickness recovery after induced edema, providing the first human in vivo evidence that
            corneal pH can influence corneal hydration control. This finding raises the question of the possible effect
            that pH may have on induced corneal swelling. To explore this question, the corneal swelling response to
            hypoxia was measured while stromal pH was controlled. METHODS. Corneal edema and stromal acidosis was
            induced in ten subjects by passing a mixture of nitrogen and carbon dioxide gas across the eyes through
            tight-fitting goggles. <strong>One eye of each subject received 100% N2, whereas the contralateral eye
                received a mixture of 95% N2 and 5% CO2. Exposures of 95% N2 + 5% CO2 lower pH on average to 7.16 versus
                7.34 for 100% N2 alone.</strong> Before and after 2.5 hours of gas exposure, central corneal thickness
            (CCT) was measured. RESULTS. <strong>Eyes exposed to the lower pH environment (eg, N2 + CO2) developed less
                change in CCT</strong> compared to the eyes receiving N2 alone. Overall increase in CCT was 29.9 +/- 5.3
            microns for eyes exposed to the 95% N2 + 5% CO2 gas mixture, versus 37.1 +/- 4.8 microns for 100% N2 <strong
            >eyes (P &lt; 0.0001). CONCLUSIONS. The corneal swelling response to hypoxia can be reduced by lowering
                stromal pH. Because changes in corneal pH alone have not been found to alter steady-state CCT, it is
                proposed that pH
            </strong>
            exerts its effect only under non-steady-state conditions (ie, corneal swelling and deswelling). This
            suggests that acidosis may produce changes in the <strong>rate of lactate metabolism</strong> or alter
            endothelial hydraulic conductivity."

            received little support until about thirty years ago when biochemical studies were set up to explore the

            studies were encouraging in that exposure to sunlight caused some changes seen in cataractous lenses, but
            eventually the hypothesis was rejected because the first change in the laboratory was the destruction of

            not be produced artificially in the laboratory using sunlight or UV exposure. Exposure of laboratory animals

            conjunctivitis, iritis and inflammation. The cornea seems more sensitive than the lens, which is not
            surprising, as it gets the first chance to absorb damaging UV. The biochemical rejection of the hypothesis
            coincided with the re-start of the epidemiological studies. Most of these are simply latitude studies and

            severity of early cortical cataract was induced in lenses isolated from male Wistar rats aged 6 weeks by

            E-treated lenses, but not in the vitamin E-untreated lenses. The vitamin E-untreated lenses showed a
            decrease in vitamin E content and an increase in water content in addition to further increases in LPO
            content and Na+/K+ ratio and further decreases in GSH content and GAP-DH and Na+,K(+)-ATPase activities. In
            contrast, the changes of these components and enzymes except for GSH were attenuated in the vitamin

            that "predigested" hydrolized protein and manufactured free amino acids are more easily assimilated than
            real proteins, and that they are not toxic. Even if free amino acids could be produced industrially without
            introducing toxins and allergens, they wouldn't be appropriate for nutritional use.
        </p>
        <p>
            Although some research shows that babies up to the age of 18 months can assimilate free amino acids, a baby
            formula containing hydrolyzed protein was associated with decreased serum albumin, which suggests that it
            interfered with protein synthesis.
        </p>
        <p>
            The myth that free amino acids are "natural nutritional substances" has been used to promote the use of many
            products besides MSG, including aspartame, chelated minerals, and tryptophan.
        </p>
        <p>
            Although several amino acids can be acutely or chronically toxic, even lethal, when too much is eaten,
            tryptophan is the only amino acid that is also carcinogenic. (It can also produce a variety of toxic
            metabolites, and it is very susceptible to damage by radiation.) Since tryptophan is the precursor of
            serotonin, the amount of tryptophan in the diet can have important effects on the way the organism responds
            to stress, and the way it develops, adapts, and ages.
        </p>
        <p>
            When an inflammatory disease (eosinophilia-myalgia syndrome) was noticed in people using tryptophan tablets
            (1989-90), there was an intense campaign to exonerate the tryptophan itself by blaming the reaction on an
            impurity in one company's product. But the syndrome didn't occur only in the people who used that company's
            product, and similar changes can be produced by a high-tryptophan diet (Gross, et al., 1999).
        </p>
        <p>
            There are people who advocate the use of tryptophan supplementation or other means to increase serotonin in
            the tissues as a treatment for the fibromyalgia syndrome, but the evidence increasingly suggests that
            excessive serotonin, interfering with muscle mitochondria, is a major factor in the development of that
            syndrome.
        </p>

        <p>
            In 1965, Hans Selye showed that the injection of serotonin caused muscular dystrophy. Subsequent studies
            suggest that serotonin excess is involved in both muscular and nervous dystrophy or degeneration. (O'Steen,
            1967; Narukami, et al., 1991; Hanna and Peat, 1989.)
        </p>
        <p>
            The fatigue produced by "over-training" is probably produced by a tryptophan and serotonin overload,
            resulting from catabolism of muscle proteins and stress-induced increases in serotonin. Muscle catabolism
            also releases a large amount of cysteine, and cysteine, methionine, and tryptophan suppress thyroid function
            (Carvalho, et al., 2000). Stress also liberates free fatty acids from storage, and these fatty acids
            increase the uptake of tryptophan into the brain, increasing the formation of serotonin. Since serotonin
            increases ACTH and cortisol secretion, the catabolic state tends to be self-perpetuating. This process is
            probably a factor influencing the rate of aging, and contributing to the physiological peculiarities of
            aging and depression.
        </p>
        <p>
            Malnutrition, and specifically protein deficiency, produces an inflammatory state that involves extreme
            serotonin dominance. Stress or malnutrition prenatally or in infancy leads to extreme serotonin dominance in
            adulthood. Other functions of tryptophan are reduced, as more of it is turned into serotonin.
        </p>
        <p>
            Decreasing tryptophan or decreasing serotonin improves learning and alertness, while increased serotonin
            impairs learning.
        </p>
        <p>
            Tryptophan is an essential amino acid for reproduction and growth of the young animal. Most research on the
            nutritional requirements for amino acids has been done on farm animals, because of the economic incentive to
            find the cheapest way to produce the fastest growth. Farmers aren't interested in the nutritional factors
            that would produce the longest-lived pigs. Some research has been done on the amino acid requirements of
            rats over a significant part of their short lifespans. In rats and farm animals, the amount of tryptophan
            required decreases with time as the rate of growth slows.
        </p>
        <p>
            In some ways, rats never really mature, since they keep growing for nearly their whole lifespan. Their
            growth stops just a short time before they die, which is usually around the age of two or three years. (At
            this age, rats' cells still retain approximately the same high water content seen in the cells of a two
            year-old child.) They usually become infertile about half-way through their lifespan. If we try to draw
            conclusions about amino acid requirements from the rat studies, I think we would want to extrapolate the
            curve for the decreasing need for tryptophan, far beyond the point seen during the rat's short life. And
            those "requirements" were determined according to the amounts that produced a maximum rate of growth, using
            the index of the pig farmers, as if the rats were being studied for possible use as meat.
        </p>

        <p>
            When rats were fed a diet completely lacking tryptophan for a short period, or a diet containing only one
            fourth of the "normal" amount for a more prolonged period, the results were surprising<strong>:</strong>
            They kept the ability to reproduce up to the age of 36 months (versus 17 months for the rats on the usual
            diet), and both their average longevity and their maximum longevity increased significantly. They looked and
            acted like younger rats. (A methionine-poor diet also has dramatic longevity-increasing effects.)
        </p>
        <p>
            On the tryptophan-poor diet, the amount of serotonin in the brain decreased. When brain serotonin decreases,
            the level of testosterone in male animals increases. More than 20 years ago, a chemical
            (p-chlorophenylalanine) that inhibits serotonin synthesis was found to tremendously increase libido.
        </p>
        <p>
            In old age, the amount of serotonin in the brain increases. This undoubtedly is closely related to the
            relative inability to turn off cortisol production that is characteristic of old age (Sapolsky and Donnelly,
            1985). Hypothyroidism increases the formation of serotonin, as does cortisol (Henley, et al., 1997, 1998;
            Neckers and Sze, 1976).
        </p>
        <p>
            In white hair, the amount of tryptophan is higher than in hair of any other color. Although serotonin and
            tryptophan are very important during rapid growth, their presence in senile tissues is probably closely
            associated with the processes of decline. The hair loss that occurs in hypothyroidism, postpartum syndrome,
            and with the use of drugs such as St. John's wort (which can also cause the "serotonin syndrome") could be
            another effect of excess serotonin.
        </p>
        <p>
            Serotonin stimulates cell division and tends to increase the formation of connective tissue, so its
            formation should be closely regulated once full growth is achieved. It contributes to the age- or
            stress-related thickening of blood vessels, and other fibrotic processes that impair organ function.
        </p>
        <p>
            The metabolic rate (eating more without gaining extra weight) and ability to regulate body temperature are
            increased by early tryptophan deprivation. (Ashley and Curzon, 1981; Segall and Timiras, 1975.) The ability
            to oxidize sugar is impaired by serotonin, and several drugs with antiserotonin actions are being used to
            treat diabetes and its complications, such as hypertension, obesity, and foot ulcers.
        </p>
        <p>
            An excess of tryptophan early in life, stress, or malnutrition, activates the system for converting
            tryptophan into serotonin, and that tendency persists into adulthood, modifying pituitary function, and
            increasing the incidence of pituitary and other cancers.
        </p>

        <p>
            Serotonin's contribution to high blood pressure is well established. It activates the adrenal cortex both
            directly and through activation of the pituitary. It stimulates the production of both cortisol and
            aldosterone. It also activates aldosterone secretion by way of the renin-angiotensin system. Angiotensin is
            an important promoter of inflammation, and contributes to the degeneration of blood vessels with aging and
            stress.<strong> It can also promote estrogen production.</strong>
        </p>
        <p>
            In the traditional diet, rather than just eating muscle meats, all the animal parts were used. Since
            collagen makes up about 50% of the protein in an animal, and is free of tryptophan, this means that people
            were getting about half as much tryptophan in proportion to other amino acids when they used foods such as
            "head cheese," ox-tails, and chicken feet.
        </p>
        <p>
            While some of the toxic effects of an excess of individual amino acids have been investigated, and some of
            the protective or harmful interactions resulting from changing the ratios of the amino acids have been
            observed, the fact that there are about 20 amino acids in our normal diet means that there is an enormous
            number of possibilities for harmful or beneficial interactions.
        </p>
        <p>
            The optimal quantity of protein in the diet has traditionally been treated as if it were a matter that could
            be resolved just by observing the rate of growth when a certain protein is given in certain quantities,
            along with "standard amounts" of calories and other nutrients. This kind of research has been useful to
            farmers who want to find the cheapest foods that will produce the biggest animals in the shortest time. But
            that kind of research climate has spread a degraded concept of nutrition into the culture at large,
            influencing medical ideas of nutrition, the attitudes of consumers, and the policies of governmental
            regulatory agencies.
        </p>
        <p>
            When synthetic amino acids are used to supplement natural proteins, they are usually chosen according to
            irrelevant models of the "ideal protein's" composition, and many toxic contaminants are invariably present
            in the synthetic free amino acids.
        </p>
        <p>
            For the present, the important thing is to avoid the use of the least appropriate food products, while
            choosing natural foods that have historical, epidemiological, and biochemical justification.
        </p>
        <p>
            Whey has been promoted as a protein supplement, but it contains a slightly higher proportion of tryptophan
            than milk does. Cheese (milk with the whey removed) contains less tryptophan. Some people have been
            encouraged to eat only the whites of eggs, "to avoid cholesterol," but the egg albumin is rich in
            tryptophan.
        </p>

        <p>
            The expensive tender cuts of meat contain excessive amounts of cysteine and tryptophan, but bone broth
            (gelatin) and the tougher cuts of meat contain more gelatin, which lacks those amino acids. Many fruits are
            deficient in tryptophan, yet have very significant quantities of the other amino acids. They also contain
            some of the "carbon skeleton" (keto-acid) equivalents of the essential amino acids, which can be converted
            to protein in the body.

            Serotonin excess produces a broad range of harmful effects<strong>:</strong> Cancer, inflammation, fibrosis,
            neurological damage, shock, bronchoconstriction, and hypertension, for example. Increased serotonin impairs
            learning, serotonin antagonists improve it.
        </p>
        <p>
            The simplest, nonessential, amino acid, glycine, has been found to protect against carcinogenesis,
            inflammation, fibrosis, neurological damage, shock, asthma, and hypertension. Increased glycine improves
            learning (Handlemann, et al., 1989; File, et al., 1999), glycine antagonists usually impair it. Its
            antitoxic and cytoprotective actions are remarkable. Collagen, besides being free of tryptophan, contains a
            large amount of glycine--32% of its amino acid units, 22% of its weight.
        </p>
        <p>
            The varied antiinflammatory and protective effects of glycine can be thought of as an antiserotonin action.
            For example, serotonin increases the formation of TNF (tumor necrosis factor, also called cachectin),
            glycine inhibits it. In some situations, glycine is known to suppress the formation of serotonin.<strong>
                Antagonists of serotonin can potentiate glycine's effects</strong> (Chesnoy-Marchais, et al., 2000).
            People who ate traditional diets, besides getting a lower concentration of tryptophan, were getting a large
            amount of glycine in their gelatin-rich diet.
        </p>
        <p>
            Gelatin, besides being a good source of glycine, also contains a large amount of proline, which has some
            antiexcitatory properties similar to glycine.
        </p>

        <p>
            If a half-pound of steak is eaten, it would probably be reasonable to have about 20 grams of gelatin at
            approximately the same time. Even a higher ratio of gelatin to muscle meat might be preferable.
        </p>
        <p>
            Carbon dioxide, high altitude, thyroid, progesterone, caffeine, aspirin, and decreased tryptophan
            consumption protect against excessive serotonin release. When sodium intake is restricted, there is a sharp
            increase in serotonin secretion. This accounts for some of the antiinflammatory and diuretic effects of
            increased sodium consumption--increasing sodium lowers both serotonin and adrenalin.
        </p>
        <p>
            The polyunsaturated oils interact closely with serotonin and tryptophan, and the short and medium chain
            saturated fatty acids have antihistamine and antiserotonin actions. Serotonin liberates free fatty acids
            from the tissues, especially the polyunsaturated fats, and these in turn liberate serotonin from cells such
            as the platelets, and liberate tryptophan from serum albumin, increasing its uptake and the formation of
            serotonin in the brain. Saturated fats don't liberate serotonin, and some of them, such as capric acid found
            in coconut oil, relax blood vessels, while linoleic acid constricts blood vessels and promotes hypertension.
            Stress, exercise, and darkness, increase the release of free fatty acids, and so promote the liberation of
            tryptophan and formation of serotonin. Increased serum linoleic acid is specifically associated with
            serotonin-dependent disorders such as migraine.
        </p>
        <p>
            Coconut oil, because of its saturated fatty acids of varied chain length, and its low linoleic acid content,
            should be considered as part of a protective diet.
        </p>
        <p>
            In the collagen theory of aging, it is argued that changes in the extracellular matrix are responsible for
            isolating cells from their environment, reducing the availability of nutrients and oxygen, and reducing
            their ability to send and receive the chemical signals that are needed for correct adaptive functioning.
        </p>
        <p>
            In diabetes, basement membranes are thickened, and in a given volume of tissue there are fewer capillaries.
            This effect probably involves excessive serotonin<em> </em>
            (Kasho, et al., 1998). Old animals contain a higher proportion of collagen. Old tendons (or tendons that
            have been exposed to excessive estrogen, which stimulates the formation of collagen) are more rigid, and
            behave almost as if they have been partly cooked. In diseases such as carcinoid, in which very large amounts
            of serotonin are released systemically, fibrosis is exaggerated, and may be the direct cause of death.
            Radiation and oxygen deprivation also lead to increased tissue fibrosis.
        </p>
        <p>
            In specific fibrotic conditions, such as cirrhosis of the liver, it is known that glycine and saturated fats
            can reverse the fibrosis. In fibrosis of the heart, thyroid hormone is sometimes able to reverse the
            condition.
        </p>

        <p>
            I think these facts imply that excessive tryptophan, estrogen, and polyunsaturated fats contribute
            significantly, maybe decisively, to the degenerative changes that occur in aging. Experiments have
            separately shown that reducing dietary tryptophan or unsaturated fats can extend the healthy lifespan, and
            several antiestrogenic interventions (removal of the pituitary, or supplementing with progesterone) can slow
            age-related changes and delay degenerative diseases. Since these factors interact, each tending to promote
            the others, and also interact with exogenous toxins, excess iron accumulation, and other stressors, it would
            be reasonable to expect greater results when several of the problems are corrected at the same time.

            platelet serotonin content and plasma stearic, palmitic, oleic and linoleic acids were estimated in 10
            migrainous patients before, during and after a migraine attack. Total and individual plasma FFA levels rose
            and platelet serotonin fell in most patients. Comparison of the pre-headache and headache mean values showed

                serotonin content estimated before and after the ingestion of 20g linoleic acid. All showed a
                significant fall in platelet serotonin in the post-ingestion period. It is shown that linoleic acid
                releases platelet serotonin in vitro, and this study suggests that it has the same action in

            during migraine may serve as a source of increased prostaglandin E1 (PGE1) synthesis. It is<strong>

            which can aggravate the clinical symptoms of migraine.

                Effects of acute physical exercise on central serotonergic systems.</strong>
            "This paper reviews data concerning the effects of acute physical exercise (treadmill running) in trained
            rats. Works from the 1980's have established that<strong>
                acute running increases brain serotonin (5-hydroxytryptamine: 5-HT) synthesis in two ways.
                Lipolysis-elicited release of free fatty acids in the blood compartment displaces the binding of the
                essential amino acid tryptophan to albumin, thereby increasing the concentration of the so-called "free
                tryptophan" portion, and because exercise increases the ratio of circulating free tryptophan to the sum
                of the concentrations of the amino acids that compete with tryptophan</strong> for uptake at the
            blood-brain barrier level, tryptophan enters markedly in the brain compartment. However, this marked
            increase in central tryptophan levels increases only to a low extent brain 5-HT synthesis, as assessed by
            the analysis of 5-hydroxyindoleacetic acid levels, thereby suggesting that exercise promotes feedback
            regulatory mechanisms. Indirect indices of 5-HT functions open the<strong>
                possibility that acute exercise-induced increases in 5-HT biosynthesis are associated with (or lead to)
                increases in 5-HT release."</strong>

            and mood, using a double-blind, randomized, crossover design. Compared with the young group, the middle-aged
            group had significantly poorer verbal episodic memory, focused, divided, and sustained attention; they also
            differed in their subjective responses at the end of testing. Bioglycin significantly improved retrieval
            from episodic memory in both the young and the middle-aged groups, but it did not affect focused or divided
            attention. However, the middle-aged men significantly benefited from Bioglycin in the sustained-attention
            task. The effects of Bioglycin differed from those of other cognitive enhancers in that it was without
            stimulant properties or significant effects on mood, and it primarily improved memory rather than attention.
            It is likely to be of benefit in young or older people in situations where high retrieval of information is
            needed or when performance is impaired by jet lag, shift work, or disrupted sleep. It may also benefit the
            impaired retrieval shown in patients with schizophrenia, Parkinson's disease, and Huntington's disease.

            Morelia. Several brain regions are involved in the learning process that is integrated from sensorial
            inputs. It is thereafter consolidated in short- (STM) or long-term memory. Serotonin is strongly related to
            both types of memory, and particularly, to STM, however, its regulatory role is still unclear. In this
            study, the effects of tryptophan (TRY) restriction on learning and STM were evaluated. Ten Sprague-Dawley
            female rats were fed with a TRY-restricted diet (0.15g/100g) starting from postnatal Day 21. At 21, 40, and
            60 days of age, 5 trials per animal were carried out in a "hard-floor"-Biel maze, after 24 h of water
            abstinence. The number of errors per trial were registered before reaching<strong> </strong>

            the goal.<strong>
                At both 40 and 60 days, experimental rats committed less errors than controls. Likewise, the
                TRY-restricted group learned the task from the second trial on, whereas controls did not solve it until
                the third trial.
            </strong>TRY restriction, and therefore brain serotonin reduction, could impair normal cholinergic activity
            in some areas such as the hippocampus and the cerebral cortex, where involvement in learning and memory is
            well documented. Morphological and neurochemical plastic events could also be related to the more efficient
            performance of the task by the TRY-restricted rats.

            (Hypo) or maintained as euthyroid controls (Eu) to examine general cardiovascular responsiveness [experiment
            I (Exp I)]; responsiveness to a serotonin (5-HT2) agonist, dl-2,5-dimethoxy-4-iodoamphetamine [DOI
            intracerebroventricularly; experiment II (Exp II)]; or responsiveness to a 5-HT(1A) agonist
            dl-8-hydroxydipropyl-aminotetralin hydrobromide [8-OH-DPAT intracerebroventricularly; experiment III (Exp
            III)]. In Exp I, intravenous infusions of phenylephrine and nitroprusside provided little evidence that
            findings in Exp II and III were caused by generalized impairment in cardiovascular responsiveness in Hypo.
            In Exp II and III, Eu and Hypo were given either intra-arterial atropine or vehicle. Atropine significantly
            elevated heart rate (Exp II and III) and mean arterial pressure (Exp II) in Eu only. When compared with Eu,
            Hypo had a reduced pressor response (5.2 vs. 20.1%), an attenuated pulse pressure response (19.3 vs. 35.4%),
            and a more robust bradycardia (-17.7 vs. -7.0%) in response to DOI. These differences were atropine
            sensitive. In Exp III, Hypo had larger decrements in mean arterial pressure (-9.0 vs. -5.1%), heart rate (
            -13.9 vs. - 7.7%), and body temperature (-4.5 vs. -2.7%) in response to 8-OH-DPAT in comparison to Eu.
            Parasympathetic involvement in the differential responses to 8-OH-DPAT was less clear than with DOI.
            Deranged autonomic control in hypothyroidism may be caused, in part, by changes in central serotonergic
            activity.

                Nutritional recovery does not reverse the activation of brain serotonin synthesis in the ontogenetically

            Investigacion Biomedica del Centro Medico Nacional, I.M.S.S. Mexico, D.F. In the present work we confirm
            that gestational malnutrition effects body and brain composition and results in an activation of the
            synthesis of the brain neurotransmitter 5-hydroxytryptamine. These results also demonstrate more activity of
            the rate-limiting enzyme tryptophan hydroxylase in the malnourished fetal and postnatal brain. However, the
            activity of this enzyme remains increased in the brain of nutritionally recovered animals accompanied by an
            increase in the synthesis of 5-hydroxytryptamine. We therefore suggest that, in the nutritionally recovered
            animal, the mechanism of activation of this biosynthetic path in the brain may be not dependent on the
            increased<strong>
                availability of free L-tryptophan observed in malnourished animals, but might be due to a specific
                change in the enzyme complex itself. This hypothesis is</strong> supported by the fact that plasma free

            Torre P, Tamarit-Torres J The lipolytic action of serotonin on isolated adipocytes from the adipose tissue
            of rats has been studied. The adipocytes were incubated in serotonin 10(-6) M. Changes both in concentration
            and composition of the free intra and extracellular fatty acids as well as diacylglycerides through liquid
            gas chromatography were evaluated at different intervals. A lower concentration of<strong>
                free fatty acids and diacylglycerides is produced during the first minutes of incubation as well as a
                subsequent increase in the concentration of both, which becomes greatest after 20-30 minutes. The
                composition of both lipidic fractions</strong> (FFA and DAG) into fatty acids at 5, 10, 20 and 30
            minutes, is related to the composition of the triacylglycerides (TAG), since during the
            esterification<strong>
                process a decline in the DAG of linoleic and palmitoleic acid is observed, both acids arranging

                an increase in the proportion of the acids</strong>

            in the 2 position. In the FFA fraction, a higher proportion of fatty acids, preferential by arranged in
            positions 1 + 3 of the TAG's is observed. Similarly a decrease is observed in the extracellular
            concentration of FFA in the presence of serotonin with respect to the controls, a fact which has been
            described by other authors. An analysis of the present data leads us to revise the possible<strong>

            of aging were also delayed after tryptophan restriction in some organs (liver, heart, uterus, ovary, adrenal
            and spleen) but not in others (kidney, lung, aorta). Brain serotonin levels were low in tryptophan-deficient
            rats but showed remarkable capacity for rehabilitation. Effects on early and late mortality and brain levels

                advanced ages, but not as marked as those placed on the diet earlier. The average lifespan (in months
                +/- the standard error of the mean) of the rats recovering from the long-term tryptophan-deficient diets

                Patho-physiologic findings after chronic tryptophan deficiency in rats: a model for delayed growth and
                aging.</strong> Segall PE, Timiras PS. Long-Evans female rats three weeks, three months and 13-14 months
            of age were placed on tryptophan-deficient diets for periods ranging from a few months to nearly two years.
            Growth was interupted during the period of tryptophan-deficiency, but when the animals were returned to a
            complete diet, they gained weight and grew to normal size. Ability to reproduce, as indicated<strong>
                by litter production, was present at 17-28 months of age in rats which had been deprived of tryptophan,
                whereas no controls over 17 months of age produced any offspring. Other signs of delayed aging in the
                experimental group included, at advanced ages, greater longevity, as well as later onset in the
                appearance of obvious tumors, and better coat condition and hair regrowth. Many of these effects were
                also seen in pair-fed controls (fed a diet equal in amount to that</strong> eaten by the
            tryptophan-deprived rats, but with 1-tryptophan added). It is hypothesized that tryptophan deficiency delays
            growth, development and maturation of the central nervous system (CNS), in particular, by decreasing the
            levels of the neurotransmitter serotonin, for which tryptophan is the necessary precursor. In a parallel
            experiment, chronic treatment with d, 1-parachlorophenylalanine, an inhibitor of brain serotonin synthesis,
            from weaning until adulthood, also inhibited growth (body weight) and delayed sexual maturation (age of
            vaginal opening). These observations suggest that diets deficient in tryptophan or restricted in calories
            can affect maturation and aging by interfering with CNS protein synthesis, or neurotransmitter metabolism,
            or both.

            Unsaturated Vegetable Oils: Toxic
        </h1>

        <p>GLOSSARY:</p>
        <p>
            Immunodeficiency (weakness of the immune system) can take many forms. AIDS, for example, refers to an
            immunodeficiency which is "acquired," rather than "inborn." Radiation and vegetable oils can cause "acquired
            immunodeficiency." Unsaturated oils, especially polyunsaturates, weaken the immune system's function in ways
            that are similar to the damage caused by radiation, hormone imbalance, cancer, aging, or viral infections.
            The media discuss sexually transmitted and drug-induced immunodeficiency, but it isn't yet considered polite
            to discuss vegetable oil-induced immunodeficiency.
        </p>
        <p></p>
        <p>
            Unsaturated oils: When an oil is saturated, that means that the molecule has all the hydrogen atoms it can
            hold. Unsaturation means that some hydrogen atoms have been removed, and this opens the structure of the
            molecule in a way that makes it susceptible to attack by free radicals.
        </p>
        <p>
            Free radicals are reactive molecular fragments that occur even in healthy cells, and can damage the cell.
            When unsaturated oils are exposed to free radicals they can create chain reactions of free radicals that
            spread the damage in the cell, and contribute to the cell's aging.
        </p>
        <p>
            Rancidity of oils occurs when they are exposed to oxygen, in the body just as in the bottle. Harmful free
            radicals are formed, and oxygen is used up.
        </p>
        <p>
            Essential fatty acids (EFA) are, according to the textbooks, linoleic acid and linolenic acid, and they are
            supposed to have the status of "vitamins," which must be taken in the diet to make life possible. However,
            we are able to synthesize our own unsaturated fats when we don't eat the "EFA," so they are not "essential."
            The term thus appears to be a misnomer. [M. E. Hanke, "Biochemistry," Encycl. Brit. Book of the Year, 1948.]
        </p>

        <p>
            Q: You say vegetable oils are hazardous to your health. What vegetable oils are you talking about?
        </p>
        <p>
            Mainly, I'm referring to soybean oil, corn oil, safflower oil, canola, sesame oil, sunflower seed oil, palm
            oil, and any others that are labeled as "unsaturated" or "polyunsaturated." Almond oil, which is used in
            many cosmetics, is very unsaturated.
        </p>
        <p>
            Chemically, the material that makes these oils very toxic is the polyunsaturated fat itself. These
            unsaturated oils are found in very high concentrations in many seeds, and in the fats of animals that have
            eaten a diet containing them. The fresh oils, whether cold pressed or consumed as part of the living plant
            material, are intrinsically toxic, and it is not any special industrial treatment that makes them toxic.
            Since these oils occur in other parts of plants at lower concentration, and in the animals which eat the
            plants, it is impossible to eat a diet which lacks them, unless special foods are prepared in the
            laboratory.
        </p>

        <p>
            These toxic oils are sometimes called the "essential fatty acids" or "vitamin F," but this concept of the
            oils as essential nutrients was clearly disproved over 50 years ago.
        </p>
        <p>
            Linoleic and linolenic acids, the "essential fatty acids," and other polyunsaturated fatty acids, which are
            now fed to pigs to fatten them, in the form of corn and soy beans, cause the animals' fat to be chemically
            equivalent to vegetable oil. In the late 1940s, chemical toxins were used to suppress the thyroid function
            of pigs, to make them get fatter while consuming less food. When that was found to be carcinogenic, it was
            then found that corn and soy beans had the same antithyroid effect, causing the animals to be fattened at
            low cost. The animals' fat becomes chemically similar to the fats in their food, causing it to be equally
            toxic, and equally fattening.
        </p>

        <p>
            These oils are derived from seeds, but their abundance in some meat has led to a lot of confusion about
            "animal fats." Many researchers still refer to lard as a "saturated fat," but this is simply incorrect when
            pigs are fed soybeans and corn.
        </p>
        <p>
            Q: How are these oils hazardous to your health?
        </p>
        <p>
            Ultimately, all systems of the body are harmed by an excess of these oils. There are two reasons for this.
            One is that the plants produce the oils for protection, not only to store energy for the germination of the
            seed. To defend the seeds from the animals that would eat them, the oils block the digestive enzymes in the
            animals' stomachs. Digestion is one of our most basic functions, and evolution has built many other systems
            by using variations of that system; as a result, all of these systems are damaged by the substances which
            damage the digestive system.
        </p>
        <p>
            The other reason is that the seeds are designed to germinate in early spring, so their energy stores must be
            accessible when the temperatures are cool, and they normally don't have to remain viable through the hot
            summer months. Unsaturated oils are liquid when they are cold, and this is necessary for any organism that
            lives at low temperatures. For example, fish in cold water would be stiff if they contained saturated fats.
            These oils easily get rancid (spontaneously oxidizing) when they are warm and exposed to oxygen. Seeds
            contain a small amount of vitamin E to delay rancidity. When the oils are stored in our tissues, they are
            much warmer, and more directly exposed to oxygen, than they would be in the seeds, and so their tendency to
            oxidize is very great. These oxidative processes can damage enzymes and other parts of cells, and especially
            their ability to produce energy.
        </p>
        <p>
            The enzymes which break down proteins are inhibited by unsaturated fats, and these enzymes are needed not
            only for digestion, but also for production of thyroid hormones, clot removal, immunity, and the general
            adaptability of cells. The risks of abnormal blood clotting, inflammation, immune deficiency, shock, aging,
            obesity, and cancer are increased. Thyroid and progesterone are decreased. Since the unsaturated oils block
            protein digestion in the stomach, we can be malnourished even while "eating well."
        </p>
        <p>
            Plants produce many protective substances to repel or injure insects and other animals that eat them. They
            produce their own pesticides. The oils in seeds have this function. On top of this natural toxicity, the
            plants are sprayed with industrial pesticides, which can concentrate in the seed oils.
        </p>
        <p>
            It isn't the quantity of these polyunsaturated oils which governs the harm they do, but the relationship
            between them and the saturated fats. Obesity, free radical production, the formation of age pigment, blood
            clotting, inflammation, immunity, and energy production are all responsive to the ratio of unsaturated fats
            to saturated fats, and the higher this ratio is, the greater the probability of harm there is.
        </p>
        <p>
            There are interesting interactions between these oils and estrogen. For example, puberty occurs at an
            earlier age if estrogen is high, or if these oils are more abundant in the diet. This is probably a factor
            in the development of cancer.
        </p>

        <p>
            All systems of the body are harmed by an excess of these oils. There are three main kinds of damage: one,
            hormonal imbalances, two, damage to the immune system, and three, oxidative damage.
        </p>
        <p>
            Q: How do they cause hormonal imbalances?
        </p>
        <p>
            There are many changes in hormones caused by unsaturated fats. Their best understood effect is their
            interference with the function of the thyroid gland. Unsaturated oils block thyroid hormone secretion, its
            movement in the circulatory system, and the response of tissues to the hormone. When the thyroid hormone is
            deficient, the body is generally exposed to increased levels of estrogen. The thyroid hormone is essential
            for making the "protective hormones" progesterone and pregnenolone, so these hormones are lowered when
            anything interferes with the function of the thyroid. The thyroid hormone is required for using and
            eliminating cholesterol, so cholesterol is likely to be raised by anything which blocks the thyroid
            function. [B. Barnes and L. Galton, Hypothyroidism, 1976, and 1994 references.]
        </p>
        <p>
            Q: How do they damage the immune system?
        </p>

        <p>
            Vegetable oil is recognized as a drug for knocking out the immune system. Vegetable oil emulsions were used
            to nourish cancer patients, but it was discovered that the unsaturated oils were suppressing their immune
            systems. The same products, in which vegetable oil is emulsified with water for intravenous injection, are
            now marketed specifically for the purpose of suppressing immunity in patients who have had organ
            transplants. Using the oils in foods has the same harmful effect on the immune system. [E. A. Mascioli, et
            al.,Lipids 22(6) 421, 1987.] Unsaturated fats directly kill white blood cells. [C. J. Meade and J. Martin,
            Adv. Lipid Res., 127, 1978.]
        </p>
        <p>
            Q: How do they cause oxidative damage?
        </p>
        <p>
            Unsaturated oils get rancid when exposed to air; that is called oxidation, and it is the same process that
            occurs when oil paint "dries." Free radicals are produced in the process.
        </p>
        <p>
            This process is accelerated at higher temperatures. The free radicals produced in this process react with
            parts of cells, such as molecules of DNA and protein and may become attached to those molecules, causing
            abnormalities of structure and function.
        </p>
        <p>
            Q: What if I eat only organically grown vegetable oils?
        </p>

        <p>
            Even without the addition of agricultural chemicals, an excess of unsaturated vegetable oils damages the
            human body. Cancer can't occur, unless there are unsaturated oils in the diet. [C. Ip, et al., Cancer Res.
            45, 1985.] Alcoholic cirrhosis of the liver cannot occur unless there are unsaturated oils in the diet.
            [Nanji and French, Life Sciences. 44, 1989.] Heart disease can be produced by unsaturated oils, and
            prevented by adding saturated oils to the diet. [J. K. G. Kramer, et al., Lipids 17, 372, 1983.]
        </p>
        <p>
            Q. What oils are safe?
        </p>
        <p>
            Coconut and olive oil are the only vegetable oils that are really safe, but butter and lamb fat, which are
            highly saturated, are generally very safe (except when the animals have been poisoned). Coconut oil is
            unique in its ability to prevent weight-gain or cure obesity, by stimulating metabolism. It is quickly
            metabolized, and functions in some ways as an antioxidant. Olive oil, though it is somewhat fattening, is
            less fattening than corn or soy oil, and contains an
        </p>
        <p>
            antioxidant which makes it protective against heart disease and cancer.
        </p>
        <p>
            Israel had the world's highest incidence of breast cancer when they allowed the insecticide lindane to be
            used in dairies, and the cancer rate decreased immediately after the government prohibited its use. The
            United States has fairly good laws to control the use of cancer-causing agents in the food supply, but they
            are not vigorously enforced. Certain cancers are several times more common among corn farmers than among
            other farmers, presumably because corn "requires" the use of more pesticides. This probably makes corn oil's
            toxicity greater than it would be otherwise, but even the pure, organically grown material is toxic, because
            of its intrinsic unsaturation.
        </p>
        <p>
            In the United States, lard is toxic because the pigs are fed large quantities of corn and soy beans. Besides
            the intrinsic toxicity of the seed oils, they are contaminated with agricultural chemicals. Corn farmers
            have a very high incidence of cancer, presumably because of the pesticides they use on their crop.
        </p>
        <p>
            Q: But aren't "tropical oils" bad for us?
        </p>
        <p>
            In general, tropical oils are much more healthful than oils produced in a cold climate. This is because
            tropical plants live at a temperature that is close to our natural body temperature. Tropical oils are
            stable at high temperatures. When we eat tropical oils, they don't get rancid in our tissues as the
            cold-climate seed oils, such as corn oil, safflower oil and soy oil, do. [R.B. Wolf, J. Am. Oil Chem. Soc.
            59, 230, 1982; R. Wolfe, Chem 121, Univ. of Oregon, 1986.]
        </p>
        <p>
            When added to a balanced diet, coconut oil slightly lowers the cholesterol level, which is exactly what is
            expected when a dietary change raises thyroid function. This same increase in thyroid function and metabolic
            rate explains why people and animals that regularly eat coconut oil are lean, and remarkably free of heart
            disease and cancer.
        </p>
        <p>
            Although I don't recommend "palm oil" as a food, because I think it is less stable than coconut oil, some
            studies show that it contains valuable nutrients. For example, it contains antioxidants similar to vitamin
            E, which lowers both LDL cholesterol and a platelet clotting factor. [B. A. Bradlow, University of Illinois,
            Chicago; Science News 139, 268, 1991.] Coconut oil and other tropical oils also contain some hormones that
            are related to pregnenolone or progesterone.
        </p>
        <p>
            Q: Isn't coconut oil fattening?

            Coconut oil is the least fattening of all the oils. Pig farmers tried to use it to fatten their animals, but
            when it was added to the animal feed, coconut oil made the pigs lean [See Encycl. Brit. Book of the Year,
            1946].
        </p>

        <p>
            Q: What about olive oil? Isn't it more fattening than other vegetable oils?
        </p>
        <p>
            In this case, as with coconut oil, "fattening" has more to do with your ability to burn calories than with
            the caloric value of the oil. Olive oil has a few more calories per quart than corn or soy oil, but since it
            doesn't damage our ability to burn calories as much as the unsaturated oils do, it is less fattening. Extra
            virgin olive oil is the best grade, and contains an antioxidant that protects against cancer and heart
            disease. [1994, Curr. Conts.]
        </p>
        <p>
            Q: Is "light" olive oil okay?
        </p>

        <p>
            No. Now and then someone learns how to make a profit from waste material. "Knotty pine" boards were changed
            from a discarded material to a valued decorative material by a little marketing skill. Light olive oil is a
            low grade material which sometimes has a rancid smell and probably shouldn't be used as food.
        </p>
        <p>
            Q: Is margarine okay?
        </p>
        <p>
            There are several problems with margarine. The manufacturing process introduces some toxins, including a
            unique type of fat which has been associated with heart disease. [Sci. News, 1974; 1991.] There are likely
            to be dyes and preservatives added to margarine. And newer products contain new chemicals that haven't been
            in use long enough to know whether they are safe.
        </p>
        <p>
            However, the basic hardening process, hydrogenation of the oils, has been found to make the oils less likely
            to cause cancer. If I had to choose between eating ordinary corn oil or corn oil that was 100% saturated, to
            make a hard margarine, I would choose the hard margarine, because it resists oxidation, isn't suppressive to
            the thyroid gland, and doesn't cause cancer.
        </p>

        <p>
            Q: What about butter?
        </p>
        <p>
            Butter contains natural vitamin A and D and some beneficial natural hormones. It is less fattening than the
            unsaturated oils. There is much less cholesterol in an ounce of butter than in a lean chicken breast [about
            1/5 as much cholesterol in fat as in lean meat on a calorie basis, according to R. Reiser of Texas A &amp; M
            Univ., 1979.].
        </p>
        <p>
            Q: Are fish oils good for you?
        </p>
        <p>
            Some of the unsaturated fats in fish are definitely less toxic than those in corn oil or soy oil, but that
            doesn't mean they are safe. Fifty years ago, it was found that a large amount of cod liver oil in dogs' diet
            increased their death rate from cancer by 20 times, from the usual 5% to 100%. A diet rich in fish oil
            causes intense production of toxic lipid peroxides, and has been observed to reduce a man's sperm count to
            zero. [H. Sinclair, Prog. Lipid Res. 25, 667, 1989.]
        </p>
        <p>
            Q: What about lard?
        </p>
        <p>
            In this country, lard is toxic beause the pigs are fed large quantities of corn and soy beans. Besides the
            natural toxicity of the seed oils, the oils are contaminated with agricultural chemicals. Corn farmers have
            a very high incidence of cancer, presumably because corn "requires" the use of more pesticides. This
            probably makes corn oil's toxicity greater than it would be otherwise. but even the pure, organically grown
            material is toxic, because of its unsaturation.
        </p>
        <p></p>
        <p>
            Women with breast cancer have very high levels of agricultural pesticides in their breasts [See Science
            News, 1992, 1994].
        </p>

        <p>
            Israel had the world's highest incidence of breast cancer when they allowed the insecticide lindane to be
            used in dairies, and the cancer rate decreased immediately after the government prohibited its use. The
            United States has fairly good laws to control the use of cancer-causing agents in the food supply, but they
            are not vigorously enforced. [World Incid. of Cancer, 1992]
        </p>
        <p>
            Q: I have no control over oils when eating out. What can I do to offset the harmful effects of
            polyunsaturated oils?
        </p>
        <p>
            A small amount of these oils won't kill you. It is the proportion of them in your diet that matters. A
            little extra vitamin E (such as 100 units per day) will take care of an occasional American restaurant meal.
            Based on animal studies, it would take a teaspoonful per day of corn or soy oil added to a fat-free diet to
            significantly increase our risk of cancer. Unfortunately, it is impossible to devise a fat-free diet outside
            of a laboratory. Vegetables, grains, nuts, fish and meats all naturally contain large amounts of these oils,
            and the extra oil used in cooking becomes a more serious problem.
        </p>
        <p>
            Q Why are the unsaturated oils so popular if they are dangerous?
        </p>
        <p>
            It's a whole system of promotion, advertising, and profitability.
        </p>
        <p>
            50 years ago, paints and varnishes were made of soy oil, safflower oil, and linseed (flax seed) oil. Then
            chemists learned how to make paint from petroleum, which was much cheaper. As a result, the huge seed oil
            industry found its crop increasingly hard to sell. Around the same time, farmers were experimenting with
            poisons to make their pigs get fatter with less food, and they discovered that corn and soy beans served the
            purpose, in a legal way. The crops that had been grown for the paint industry came to be used for animal
            food. Then these foods that made animals get fat cheaply came to be promoted as foods for humans, but they
            had to direct attention away from the fact that they are very fattening. The "cholesterol" focus was just
            one of the marketing tools used by the oil industry. Unfortunately it is the one that has lasted the
            longest, even after the unsaturated oils were proven to cause heart disease as well as cancer. [Study at
            L.A. Veterans Hospital, 1971.]
        </p>
        <p>
            I use some of these oils (walnut oil is very nice, but safflower oil is cheaper) for oil painting, but I am
            careful to wash my hands thoroughly after I touch them, because they can be absorbed through the skin.
        </p>
        <p><strong>SUMMARY</strong></p>
        <p>
            Unsaturated fats cause aging, clotting, inflammation, cancer, and weight gain.
        </p>
        <p>
            Avoid foods which contain the polyunsaturated oils, such as corn, soy, safflower, flax, cottonseed, canola,
            peanut, and sesame oil.
        </p>
        <p>
            Mayonnaise, pastries, even candies may contain these oils; check the labels for ingredients.
        </p>
        <p>
            Pork is now fed corn and soy beans, so lard is usually as toxic as those oils; use only lean pork.
        </p>
        <p>
            Fish oils are usually highly unsaturated; "dry" types of fish, and shellfish, used once or twice a week, are
            good. Avoid cod liver oil.
        </p>

        <p>
            Use vitamin E.
        </p>
        <p>
            Use coconut oil, butter, and olive oil.
        </p>
        <p>
            Unsaturated fats intensify estrogen's harmful effects.

        <p><strong>Essential Fatty Acids ("EFA"): A Technical Point</strong></p>
        <p>
            Those fatty acids, such as linoleic acid and linolenic acid, which are found in linseed oil, soy oil, walnut
            oil, almond oil, corn oil, etc., are essential for the spontaneous development of cancer, and also appear to
            be decisive factors in the development of age pigment, alcoholic cirrhosis of the liver, diabetes, obesity,
            stress-induced immunodeficiency, some aspects of the shock reaction, epilepsy, brain swelling, congenital
            retardation, hardening of the arteries, cataracts, and other degenerative conditions. They are possibly the
            most important toxin for animals.
        </p>
        <p>
            The suppression of an enzyme system is characteristic of toxins. The "EFA" powerfully, almost absolutely,
            inhibit the enzyme systems--desaturases and elongases--which make our native unsaturated fatty acids.
        </p>
        <p>
            After weaning, these native fats gradually disappear from the tissues and are replaced by the EFA and their
            derivatives. The age-related decline in our ability to use oxygen and to produce energy corresponds closely
            to the substitution of linoleic acid for the endogenous fats, in cardiolipin, which regulates the crucial
            respiratory enzyme, cytochrome oxidase.
        </p>
        <p>
            Although the fish oils are less effective inhibitors of the enzymes, they are generally similar to the seed
            oils in their ability to promote cancer, age-pigment formation, free radical damage, etc. Their only special
            nutritional value seems to be their vitamin A and vitamin D content. Since vitamin A is important in the
            development of the eye, it is interesting that claims are being made for the essentiality of some of the
            fatty acid components of fish oil, in relation to the development of the eye.
        </p>
        <p>
            The polyunsaturated oils from seeds are recommended for use in paints and varnishes, but skin contact with
            these substances should be avoided.

            For fifty years, the mass media have been making the public think about the fats in their diet, filling the
            culture with clich"s about bad saturated animal fats that raise cholesterol, or lately the trans-fats in
            margarine, and images of arteries clogged by bad fats. The public instruction about the fats we should eat
            resembles the owner's manual for a car, that tells you what kind of motor oil and fuel and coolant to use;
            they are telling us that they know how our body works, and that they know what it needs. But now, even after
            the human genome has supposedly been partly "decoded," the biological functions of the fats have hardly
            begun to be investigated.
        </p>

        <p>
            To understand the present issues regarding fats in nutrition and medicine it's helpful to look at the
            historical development of biochemical and physiological fat research in a variety of contexts, including
            agriculture and economics, as well as considering the effects of the changing ideas about cell structure,
            vitamins, hormones, immunology, brain development, evolution, and the growing understanding of the way
            physiology interacts with ecology. We need to recognize the complexity of the physiology of fats, to
            appreciate the complexity of the living organism.

            Financial considerations have driven fat research in very obvious ways. In 1883, Mark Twain described how
            commercial fraud was making use of new technology to substitute cheap fats and oils for butter and olive
            oil.. Hard fats such as tallow, which had been used for making soap and candles, began to be widely used as
            a substitute for butter in the 19th century. Around 1912, chemists found economical ways to solidify (for
            use as a butter substitute) the very cheap liquid oils, such as cottonseed oil, linseed oil, whale oil, and
            fish oils, which been used mostly as fuels or varnish. The seed oils were so cheap that meat packers quickly
            became major producers of hydrogenated cottonseed and soy oils, to extend their limited supply of lard or
            tallow for sale as shortening or margarine.
        </p>
        <p>
            Between 1912 and 1927 there were several studies that reported that animals could live on a fat-free diet,
            and that in fact they lived longer, and without the normal mortality from cancer. In the 1940s and 1950s,
            most textbooks that mentioned the idea that certain fats were essential nutrients described it as a
            controversial idea. But the oil industries used public relations effectively to sell the medical (heart
            protective) benefits of a diet containing increased amounts of linoleic and linolenic acids, which they
            called the essential fatty acids. They began citing a 1929 publication (by G. Burr and M. Burr) that claimed
            to demonstrate the essentiality of those fatty acids, while ignoring the publications that pointed in
            different directions.
        </p>
        <p>
            The cheapness of the seed oils led to their use in animal feeds, to promote growth. By the 1940s, the
            polyunsaturated oils, including fish oils, were known to cause deterioration of the brain, muscles, and
            gonads in a variety of animals, and this was found to be caused mainly by their destruction of vitamin E. A
            little later, the disease called steatitis or yellow fat disease was found to be produced in various animals
            that were fed too much fish or fish oil.
        </p>
        <p>
            The reason linseed oil and fish oil were used for making varnishes and paints was that they are "drying
            oils," reacting with oxygen to polymerize and harden. The physical and chemical propertiess of the oils are
            fairly well understood, and among the polyunsaturated fatty acids (PUFA) the omega -3 fatty acids react most
            easily with oxygen. Heat, light, and moisture increase their spontaneous interactions with oxygen, and
            besides polymerizing, these oils produce a variety of reactive particles, including acrolein, which combine
            with other substances, such as cellular proteins and DNA, with highly toxic effects. At low temperatures and
            low oxygen concentrations these oils are not highly reactive. Fats that harden at low temperatures (as
            saturated fats do) wouldn't be convenient for organisms that live in a cool environment, and so organisms
            regulate the type of fat they synthesize according to the temperature of their tissues. The fact that
            certain types of polyunsaturated fatty acids function nicely in fish, worms, and insects, doesn't mean that
            they are ideal fats for mammals.
        </p>

        <p>
            The fact that vitamin E prevented or cured some of the major diseases in farm animals caused by excessive
            PUFA, and that it could retard the development of rancidity in stored oils, led quickly to the persistent
            belief that lipid peroxidation is the only toxic effect of the vegetable oils. However, the oils were being
            seen to cause other problems, including accelerated aging and obesity, but those problems weren't of
            interest to farmers, who wanted to sell plump young animals as cheaply and quickly as possible. Even fresh
            oils have toxic effects, and the oxidative damage they do is often the consequence of these other toxic
            actions.
        </p>
        <p>
            Another cheap food additive, coconut oil, was found to increase feed consumption while slowing weight gain,
            so it wasn't popular in the meat industry. The highly unsaturated seed oils had the opposite effect, of
            producing a rapid fattening of the animal, while decreasing feed consumption, so by 1950 corn and soybeans
            were widely considered to be optimal feeds for maximizing profits in the production of meat animals. It was
            at this time that the industry found that it could market the liquid oils directly to consumers, as
            health-promoting foods, without bothering to turn them into solid shortening or margarine. Somehow, few
            physiologists continued to think about the implications of metabolic slowing, obesity, and the related
            degenerative diseases.
        </p>
        <p>
            As vitamin research advanced in the 1940s, Roger Williams' lab at the Clayton Foundation Biochemical
            Institute, University of Texas at Austin, recognized the "fat deficiency disease" of the Burrs as a
            deficiency of vitamin B6, and showed that when they produced the condition with a diet similar to the one
            the Burrs had used, they could cure it by administering vitamin B6. In the early 1930s George Burr had
            discovered that animals on a fat free diet had an extremely high rate of metabolism, but he didn't
            investigate the important ramifications of that observation, such as their increased need for vitamins and
            minerals, in accordance with their rate of metabolism. The PUFA slowed metabolism, and that effect was good
            for agriculture.
        </p>

        <p>
            The commercial pressure on fat research has created a new way of writing research reports, that several
            decades earlier wouldn't have been acceptable. For example, the effects of a specific fat on a few of the
            components of a complex process such as clotting are often described in the title, introduction, and
            conclusion of an article as if they were revealing a way to prevent heart disease. The effects of
            unsaturated fats on cells <em>
                in vitro</em> are often the opposite of their effects in living animals, but editors are allowing
            authors to claim that their <em>in vitro</em>
            results justify dietary or therapeutic use of the fats. Journals of medicine and nutrition are now preferred
            sites for commercial press releases, composed to superficially resemble scientific reports.
        </p>
        <p>
            The suppressive effects of unsaturated fats on mitochondrial energy production have been widely
            investigated, since it is that effect that makes animal fattening with PUFA so economical. Rather than
            interpreting that as a toxic effect, using the innate structure and function of the mitochondrion as a point
            of reference from which to evaluate dietary components, the consumption of "good" oils is being used as the
            reference point from which to evaluate the meaning of metabolism ("efficiency is good," "low oxygen
            consumption is good"). Building on the idea that the oils are health-promoters which increase metabolic
            efficiency, the never-viable "rate of aging" theory was resuscitated: The anti-respiratory effect of PUFA is
            used (illogically) to return to the idea that aging occurs in proportion to the amount of oxygen consumed,
            because animals which lack the supposedly essential nutrients ("defective animals") consume oxygen
            rapidly--burning calories rapidly, they are supposed to be like a candle that won't last as long if it burns
            intensely. The old theory is simply resuscitated to explain why the anti-respiratory action of PUFA might be
            beneficial, justifying further promotion of their use as food and drugs.
        </p>

        <p>
            Ordinarily, in biochemistry and physiology the inhibition of an enzyme is taken as a suggestion of toxicity,
            but when the point of reference is the idea of the goodness of PUFA, the <em>activity</em> of an intrinsic
            enzyme is taken to be evidence of harm, and its <em>inhibition</em> (by PUFA) is taken to be the proper,
            healthful situation. The enzyme that produces the Mead fatty acid is strongly inhibited by PUFA seed oils
            (less strongly by fish oils), and so the presence of the Mead acid in the tissues is taken as evidence that
            the animal is suffering damage resulting from the absence of PUFA. The Mead acid happens to have some
            valuable anti-inflammatory effects, and is associated with many biological advantages, but research in that
            direction is prevented by the lack of funding.
        </p>
        <p>
            By 1920, the polyunsaturated fatty acids were recognized to inhibit proteolytic enzymes. At that time, the
            production of unsaturated fat was considered to be a feature of certain pathogens, able to overcome the
            proteolytic-phagocytic functions of the immune system.
        </p>
        <p>
            Scattered studies have found that polyunsaturated fats inhibit the proteolytic enzymes involved in the
            digestion of food, in the removal of clots, in the formation of thyroid hormone, and many other essential
            physiological processes. But currently, the only implication being drawn from this broad class of effects of
            the PUFA is that some proteolytic enzymes are involved in disease processes, and consequently increased
            consumption of PUFA would be appropriate, because of their ability to suppress a conditionally harmful
            proteolytic enzyme. Since the organism consists mainly of proteins, there are complex innate systems for
            regulating the proteolytic enzymes, activating or inactivating them as needed, and such complexity isn't
            likely to depend on variable, unstable dietary factors. Exogenous substances that inhibit some proteases
            could create an unlimited variety of functional and anatomical irregularities.
        </p>
        <p>
            Some of the interesting enzymes affected specifically by polyunsaturated fatty acids are those involved in
            hormone production. While they inhibit the formation of progesterone and androgens, they activate the
            synthesis of estrogen, which in turn activates the release of more free polyunsaturated fatty acids from the
            tissues, in a positive feedback pattern.
        </p>

        <p>
            The inhibition of detoxification enzymes by PUFA (Tsoutsikos, et al., 2004) affects many processes, such as
            the elimination of estrogen, contributing to the positive feedback between estrogen and the oils. The
            meaning of this tends to be lost, because of the estrogen industry's effective campaigns.
        </p>
        <p>
            Another situation in which fatty acids participate in a positive feedback system is the stress reaction, in
            which the released fatty acids impair mitochondrial energy production, increasing the stress and leading to
            further release of fatty acids.
        </p>
        <p>
            One of the perennial theories of aging that has remained viable is the metaplasm/lipofuscin/age pigment
            theory, the idea that a toxic material accumulates in tissues over time. The age pigment contains proteins,
            cross-linked PUFA, and metals. The inhibition of proteolytic enzymes is involved in its accumulation, and
            the ratio of PUFA to saturated fatty acids is an important factor in its formation. Estrogen is one of the
            factors that can promote the formation of age pigment, probably partly because its lipolytic action
            increases the cells' exposure to free fatty acids. The lipofuscin contributes to inhibition of proteolysis,
            probably partly through increased production of free radicals and hydrogen peroxide.
        </p>
        <p>
            The proteolytic enzymes are an essential part of innate immunity, and the highly unsaturated fatty acid,
            EPA, which is the most immunosuppressive of the fats, strongly inhibits proteolysis in some cells. The
            natural killer (NK) cells and phagocytic cells are two types of cell that are suppressed by PUFA, and they
            are involved in many kinds of physiological events, not just the killing of tumor cells and virus infected
            cells.
        </p>
        <p>
            The immunosuppressive effects of PUFA are very general. Many metabolites that are known to have harmful
            effects on the immune system are increased by the PUFA (histamine [Masini, et al., 1990], serotonin,
            lactate, nitric oxide [Omura, et al., 2001]). These substances are also involved in tumor development.
        </p>

        <p>
            Besides inhibiting enzymes and being converted into prostaglandins, the polyunsaturated fatty acids have
            direct effects, as signals (or interference with signals) on many tissues. The belief that the PUFA are
            essential nutrients has influenced the way cellular excitability thresholds are being interpreted. Anxiety
            and panic may be interpreted as alertness, calmness may be interpreted as stupidity. Specifically, long-term
            potentiation (LTP) may contribute to seizures, senility, and excitotoxicity, as well as to learning, but
            many titles and conclusions equate increased LTP with "improved LTP," implying that it has biological value
            to the animal.
        </p>
        <p>
            The ability of nerve cells to become quiescent after excitation is essential to learning and perception.
            This ability is lost with aging, as the functional balance in the brain shifts away from GABA-ergic to
            glutamatergic nerves. The polyunsaturated fatty acids promote the excitatory nervous state. The combination
            of respiratory inhibition with excitation can produce excitotoxic cell death. If the doctrine of
            "essentiality of PUFA" hadn't been so influential, different interpretations of excitatory thresholds,
            energy metabolism, and even cell structure would have been allowed to develop more fully.
        </p>
        <p>
            The concentration of polyunsaturated fats in the brain has led many people to say that the "nutritionally
            essential fatty acids," especially the omega -3 fatty acids, are essential for brain development (for the
            formation of nerve cell membranes), and for the formation of synapses, and that increasing the amount of
            those fats in the diet would be desirable. The types of argument they use simply ignore the real
            evidence<strong>:</strong>

            Cells can multiply indefinitely in culture dishes without the essential fatty acids, insects can multiply
            for generations on diets without the unsaturated fats, forming normal synapses and brains, and mammals fed
            diets with extremely small amounts of the unsaturated fats grow with perfectly normal--possibly
            superior--brains.
        </p>
        <p>
            One of the fats in the omega -9 series, that the human body can synthesize, nervonic acid, is a major
            constituent of brain tissue, but its important functions in brain development have hardly been investigated.
            Unlike the unsaturated fatty acids oleic acid, linoleic acid, and eicosapentaenoic acid (EPA), nervonic acid
            isn't associated with the "coronary risk factors," and it has been suggested that it might be used in adults
            to prevent obesity-related diseases. (Oda, et al., 2005).
        </p>
        <p>
            One major area of research that has been neglected involves the role of fats in modifying the ways in which
            proteins and nucleic acids interact with water--arguably the most basic of all physiological processes.
            Unsaturated fats are more water soluble than saturated fats, and they are involved in many problems of
            permeability and edema.
        </p>
        <p>
            In aging and evolution, there are systematic changes in tissue water content that appear to correspond to
            changes in rate of metabolism, to the degree of unsaturation of cellular fats, and to thyroid function and
            temperature. Metabolic intensity and longevity can be modified by changing the degree of saturation of fats
            in the diet and tissues, but--despite almost a century of sporadic investigations--no one has yet worked out
            in detail the most appropriate way to do this. But it has become clear that the "uncoupled" mitochondrion,
            that "wastes oxygen and calories," is protective against free radicals, cancer, and aging. Thyroid hormone
            and the absence of PUFA are important factors in supporting the "wasteful" mitochondrion.
        </p>
        <p>
            Although the complex interactions of anatomy, energy, temperature, fat nutrition, tissue water content, and
            hormones haven't been systematically investigated, some of the principles regarding the biological
            suitability of specific fats are already being applied in the limited context of therapy.
        </p>
        <p>
            At present, the most important issue is to recognize the dangers presented by the intrusion of corporate
            power into science, especially as it relates to nutrition and medicine, and to consider the implications of
            the known effects of the PUFA on all of our biological systems.
        </p>
        <p>
            The food-derived polyunsaturated fatty acids play important roles in the development of all of the problems
            associated with aging--reduced immunity, insomnia, decreased learning ability, substitution of fat for
            muscle, susceptibility to tissue peroxidation and inflammation, growth of tumors, etc., and are probably
            involved in most other health problems, even in children. If research hadn't been guided by the economic
            interests of the seed oil industry, many of those problems would have been solved by now.
        </p>
        <p>
            The influence of the mass media on science can be seen in two issues that are currently well known.
        </p>

        <p>
            A popular test used for evaluating diabetes is the measurement of glycated hemoglobin, the attachment of a
            sugar-like fragment to the protein of hemoglobin. This is used to judge whether blood sugar is being
            controlled adequately. The glycation of proteins is widely believed to be a central process in aging, and is
            often used to argue that people should reduce their sugar consumption.
        </p>
        <p>
            Another well publicized problem supposedly involving the reaction between sugars and proteins has to do with
            the discovery of the carcinogen, acrylamide, in breads and french fries. The Whole Foods Market was sued in
            California for selling whole wheat bread without a warning that it contained a carcinogen.
        </p>
        <p>
            But the changes in proteins that occur in diabetes are mainly produced by the breakdown products of
            polyunsaturated fatty acids. Acrylamide is produced largely by the reaction of PUFA with proteins.
        </p>
        <p>
            Sugar, by reducing the level of free fatty acids in the body, actually tends to protect against these toxic
            effects of the PUFA. Diabetes, like cancer, has been known for a long time to be promoted by unsaturated
            oils in the diet, rather than by sugar. The seed oil industry has been more effective than the sugar
            industry in lobbying and advertising, and the effects can be seen in the assumptions that shape medical and
            biological research.

            Herrero A, Portero-Otin M, Bellmunt MJ, Pamplona R, Barja G. "Previous comparative studies have shown that
            long-lived animals have lower fatty acid double bond content in their mitochondrial membranes than
            short-lived ones. In order to ascertain whether this trait protects mitochondria by decreasing lipid and
            protein oxidation and oxygen radical generation, the double bond content of rat heart mitochondrial
            membranes was manipulated by chronic feeding with semi-purified AIN-93G diets rich in highly unsaturated
            (UNSAT) or saturated (SAT) oils. UNSAT rat heart mitochondria had significantly higher double bond content
            and lipid peroxidation than SAT mitochondria. They also showed increased levels of the markers of protein
            oxidative damage malondialdehyde-lysine, protein carbonyls, and N(e)-(carboxymethyl)lysine adducts." "These
            results demonstrate that increasing the degree of fatty acid unsaturation of heart mitochondria increases
            oxidative damage to their lipids and proteins, and can also increase their rates of mitochondrial oxygen
            radical generation in situations in which the degree of reduction of Complex III is higher than normal.
            These observations strengthen the notion that the relatively low double bond content of the membranes of
            long-lived animals could have evolved to protect them from oxidative damage."

                and destabilize ABCA1 through a phospholipase D2 pathway.</strong> Wang Y, Oram JF. "ATP-binding
            cassette transporter ABCA1 mediates the transport of cholesterol and phospholipids from cells to HDL
            apolipoproteins and thus modulates HDL levels and atherogenesis. Unsaturated fatty acids, which are elevated
            in diabetes, impair the ABCA1 pathway in cultured cells by destabilizing ABCA1 protein." "Unsaturated but
            not saturated fatty acids stimulated phospholipase D (PLD) activity, the PLD inhibitor 1-butanol prevented
            the unsaturated fatty acid-induced reduction in ABCA1 levels, and the PLD2 activator mastoparan markedly
            reduced ABCA1 protein levels, implicating a role for PLD2 in the ABCA1 destabilizing effects of fatty
            acids." "These data provide evidence that intracellular unsaturated acyl-CoA derivatives destabilize ABCA1
            by activating a PLD2 signaling pathway."

                Since bacteria in the rumens of cows destroy unsaturated fatty acids, but don't harm vitamin E, it seems
                reasonable to suppose that beef and milk would have a better ratio of vitamin E to unsaturated fats than
                do the plants eaten by the cows.

                Toxic pesticides are found in higher concentrations in the urine and fat of slaughtered animals than in
                their livers, since the livers are detoxifying the chemicals and causing them to be excreted.
                Presumably, the animals' livers will perform the same detoxification reactions with the <strong

            Not long ago, breast feeding was socially unacceptable in the United States, and several manufacturers were
            teaching the world"s poorest women to use their baby-food formulas even when there was no clean water for
            its preparation. Industrialists have campaigned to convince the public that their by-products, from
            cotton-seed oil to shrimp shells, are "health foods." In several parts of the world, desperately poor people
            sometimes eat clay, and even clay has been promoted as a health food. Almost anything becomes "food," when
            people are under economic and social pressure. If these things aren"t acutely toxic, they can become part of
            our "normal" diet.
        </p>

        <p>
            Our instincts give us a few clues about our nutritional needs, such as thirst, the hunger for salt, the
            pleasantness of sweet things, and the unpleasantness of certain odors or very acrid or bitter tastes. People
            who are constitutionally unable to taste certain bitter chemicals find certain vegetables less
            objectionable; their instinctive guidance has become less clear. But within the boundaries of cravings and
            disgust, habits and customs become the dominant forces in diet. "Professional dietitians" and other
            "experts" primarily function as enforcers of cultural prejudice.
        </p>
        <p>
            The manufacturers of pureed vegetables for babies used to put large amounts of salt, sugar, and monosodium
            glutamate into their products, because the added chemicals served as instinctual signals that made the
            material somewhat acceptable to the babies. There was no scientific basis for providing these vegetables to
            babies in a form that they would accept, but it was a profitable practice that was compatible with the
            social pressure against prolonged breast feeding.

            Poor people, especially in the spring when other foods were scarce, have sometimes subsisted on foliage such
            as collard and poke greens, usually made more palatable by cooking them with flavorings, such as a little
            bacon grease and lots of salt. Eventually, "famine foods" can be accepted as dietary staples. The fact that
            cows, sheep, goats and deer can thrive on a diet of foliage shows that leaves contain essential nutrients.
            Their minerals, vitamins, and amino acids are suitable for sustaining most animal life, if a sufficient
            quantity is eaten. But when people try to live primarily on foliage, as in famines, they soon suffer from a
            great variety of diseases. Various leaves contain antimetabolic substances that prevent the assimilation of
            the nutrients, and only very specifically adapted digestive systems (or technologies) can overcome those
            toxic effects.
        </p>

        <p>
            Some plants have specific "pests," such as insects, that have adapted to be resistant to that plant"s
            toxins, but if the plant and its predator are to survive, there has to be a balance between the plant
            tissue"s digestibility and its toxicity. Injury of a plant stimulates it to make increased amounts of its
            defensive chemicals. Plant toxins are known to be specific for animal tissues; for example, a toxin will
            inhibit the action of an enzyme from an animal, but a plant enzyme that catalyzes the same reaction won"t be
            affected.
        </p>
        <p>
            Plant defensive chemicals can have beneficial uses as drugs. Plants are important sources for chemicals used
            in chemotherapy of cancer, with the purpose of stopping cell division. Other plant drugs can stimulate cell
            division. The drug from one plant will sometimes protect cells against the toxic effects of another plant.
            The use of any drug that isn"t a natural part of animal physiology will have many biological effects, so
            that a beneficial drug action will usually be accompanied by unwanted side-effects. An antioxidant may turn
            out to disrupt the endocrine system, an antiinflammatory drug may be mutagenic or carcinogenic.
        </p>
        <p>
            A particular plant will have a variety of defensive chemicals, with specific functions. Underground, the
            plant"s roots and tubers are susceptible to attack by fungi and nematodes. The leaves, stems, and seeds are
            susceptible to attack by insects, birds, and grazing animals. Since the plant"s seeds are of unique
            importance to the plant, and contain a high concentration of nutrients, they must have special protection.
            Sometimes this consists of a hard shell, and sometimes of chemicals that inhibit the animal"s digestive
            enzymes. Many plants have evolved fruits that provide concentrated food for animals, and that serve to
            distribute the seeds widely, as when a bird eats a berry, and excretes the undigested seed at a great
            distance. If the fruit were poisonous, it wouldn"t serve the plant"s purpose so well. In general, the
            plant"s most intense toxins are in its seeds, and the fruits, when mature, generally contain practically no
            toxins. Roots contain chemicals that inhibit microorganisms, but because they aren"t easily accessible by
            grazing animals and insects, they don"t contain the digestive inhibitors that are more concentrated in the
            above-ground organs of the plant.
        </p>
        <p>
            The toxins of plants include phenols, tannins, lectins/agglutinins, and trypsin-inhibitors, besides
            innumerable more specific metabolic inhibitors, including "anti-vitamins." Unsaturated fats themselves are
            important defenses, since they inhibit trypsin and other proteolytic enzymes, preventing the assimilation of
            the proteins that are present in seeds and leaves, and disrupting all biological processes that depend on
            protein breakdown, such as the formation of thyroid hormone and the removal of blood clots.
        </p>
        <p>
            Generally, fruits, roots, and tubers provide a high concentration of nutrients along with low concentrations
            of toxic antimetabolic substances.
        </p>
        <p>
            While nutritional reference tables often show fruits and potatoes as having about 2% protein content, while
            nuts, grains, and legumes are shown with a high protein content, often in the range of 15% to 40%, they
            neglect to point out that fruits and potatoes have a very high water content, while that of the seeds is
            extremely low. The protein content of milk is about 3%, which according to the charts would suggest that it
            is inferior to beans and grains. In fact, the protein value of grain is negligible, mainly because seeds
            contain their protein in a storage form, that is extremely rich in nitrogen, but poor in essential amino
            acids. Special preparation is needed to reduce the toxicity of seeds, and in the case of beans, these
            methods are never very satisfactory.
        </p>

        <p>
            Besides their specific defensive toxins and antimetabolites, plants are major sources of allergens. The
            allergenicity of a food depends on the sensitivity of the individual, as well as on the growth conditions of
            the plant. The use of extremely toxic pesticides has affected both the crops and the sensitivity of the
            human population to allergens. Sensitivities induced originally by toxic pesticides used on certain crops
            can probably persist after the industrial chemical has been eliminated, because the immune system is
            susceptible to "conditioning."
        </p>
        <p>
            Many types of phytochemicals are mutagenic, and some of those are carcinogenic. Bruce Ames, at the
            University of California, devised a method of screening for mutagens, using bacteria. One of his graduate
            students using the technique found that the flame retardants in children's pajamas and bedding were powerful
            mutagens, and were probably causing cancer. That event made Ames a celebrity, and in the 1980s he went on a
            lecture tour supported by the American Cancer Society. His lectures reflected the doctrine of the A.C.S.,
            that industrial chemicals aren't responsible for cancer, but that individual actions, such as smoking or
            dietary choices, are the main causes of cancer. He used a fraudulently "age adjusted" graph of cancer
            mortality, that falsely showed that mortality from all types of cancer except lung cancer had leveled off
            after the A.C.S. came into existence. He described tests in which he had compared DDT to extracts of food
            herbs, and found DDT to be less mutagenic than several of the most commonly used flavoring herbs. His
            message, which was eagerly received by his audience of chemistry and biology professors, was that we should
            not worry about environmental pollution, because it's not as harmful as the things that we do to ourselves.
            He said that if everyone would eat more unsaturated vegetable oil, and didn't smoke, they wouldn't have
            anything to worry about.
        </p>
        <p>
            For me, the significance of his experiment was that plants contain natural pesticides that should be taken
            more seriously, without taking industrial toxins less seriously.
        </p>
        <p>
            Technologies have been invented to convert vegetation into digestible protein, but at our present scientific
            and technological level, it"s better to simply minimize our use of the more toxic foods, and to direct more
            effort toward the elimination of the conditions that produce famine.
        </p>
        <p>
            Animal proteins, and fruits, because they contain the lowest levels of toxins, should form the basis of the
            diet. Not all fruits, of course, are perfectly safe--avocados, for example, contain so much unsaturated fat
            that they can be carcinogenic and hepatotoxic.
        </p>

            Protein deficiency itself contributes to the harm done by toxins, since the liver"s ability to detoxify them
            depends on adequate nutrition, especially good protein. In the 1940s, Biskind"s experiments showed that
            protein deficiency leads to the accumulation of estrogen, because the liver normally inactivates all the
            estrogen in the blood as it passes through the liver. This applies to phytoestrogens and industrial
            estrogens as well as to the natural estrogens of the body. At a certain point, the increased estrogen and
            decreased thyroid and progesterone cause infertility, but before that point is reached, the hyperestrogenism
            causes a great variety of birth defects. Deformities of the male genitals, and later, testicular cancer in
            the sons and breast cancer in the daughters, are produced by the combination of toxins and nutritional
            deficiencies.

                Mechanisms underlying Phalaris aquatica "sudden death" syndrome in sheep.</strong> Bourke CA, Carrigan
            MJ New South Wales Agriculture, Agricultural Research and Veterinary Centre, Orange. Twenty outbreaks of
            Phalaris aquatica "sudden death" syndrome in sheep were investigated between 1981 and 1991. Four were
            confirmed and one was suspected, to be a cardiac disorder; 5 were confirmed and 3 were suspected, to be a
            polioencephalomalacic disorder; the aetiology of the remaining 7 outbreaks could not be determined.
            Potentially toxic levels of hydrocyanic acid (20 to 36 mg/100 g) were measured in the 3 toxic phalaris
            pastures tested. The measurement of potentially toxic levels of nitrate nitrogen (2920 micrograms/g) in
            toxic phalaris pastures by others, was noted. It is suggested that phalaris "sudden death" syndrome could
            have as many as 4 different underlying mechanisms, and<strong>
                that these might reflect the presence in the plant of a cardio-respiratory toxin, a thiaminase and amine

            In Vivo 1998 Nov-Dec;12(6):675-89. <strong>Comparative anticancer effects of vaccination and dietary factors
                on experimentally-induced cancers.</strong>
            Zusman I Laboratory of Teratology and Experimental Oncology, Koret School of Veterinary Medicine, Faculty of
            Agriculture, Food and Environmental Quality Sciences, Hebrew University of Jerusalem, Rehovot, Israel. The
            role of two major factors were analyzed in the prevention of experimentally-induced cancers: a) vaccination
            of animals with polyclonal IgG generated against the soluble p53 antigen and b) feeding of animals with
            diets rich with dietary fibers or fat. a) In vaccination, a few attempts have been made to utilize p53
            protein as a tumor suppressor. IgG generated against the cytoplasmic, soluble p53 antigen from tumor-bearing
            rats prevents the carcinogenic effect of 1,2-dimethylhydrazine (DMH) decreasing significantly the number of
            tumor-bearing rats in vaccinated group compared with non vaccinated controls and preventing benign tumors
            from becoming malignant. The antitumor effect of vaccination is accompanied by a significant increase in the
            serum-level of p53 antigen in vaccinated rats compared with non vaccinated controls. The immune response of
            a host to vaccination activates the lymph components of the spleen, and this activation is manifested by the
            multiplication of the number of lymphocytes which are generated against specific antigens. This
            multiplication is achieved by the higher division of the antigen-specific lymphoblasts with their subsequent
            transformation into plasma cells. These cells synthesize the specific protein (IgG). One such protein is the
            tumor-associated p53 protein, which is synthesized by rats against rabbit anti-p53 IgG. b) The role of
            dietary factors in the prevention of chemically induced cancer was reviewed on two models: the role of high
            fiber diets in prevention of colon cancer, and <strong>the role of high fat diets in the prevention of
                mammary gland cancer.</strong> Experiments in colon cancer showed that 20% cellulose decreased
            significantly tumor incidence caused by DMH. The tumor-preventive effect of a cellulose diet was accompanied
            by increased enzyme concentrations, such as ornithine decarboxylase, thymidine kinase and
            beta-glucuronidase. This effect was accompanied by activation of some cellular mechanisms, i.e. apoptosis,
            proliferating cell nuclear antigen (PCNA) and p53 protein synthesis. <strong>Experiments in mammary glands
                cancer showed that a 15% olive-oil diet reduced significantly the tumor incidence caused by
                9,10-dimethyl-1,2-benzanthracene. The antitumor effect of the olive-oil diet was connected to its
                content of monounsaturated fatty acids, such as oleic and palmitic acids. The promotive tumorigenic
                effects of other high-fat diets (avocado, soybeans) were associated with high content of some
                polyunsaturated fatty acids (linoleic and alpha-linolenic).</strong> Different diets have different
            targets. The effect of the same diet depends on its anti-tumor substances content. CONCLUSIONS: Vaccination
            and some diets have similar mechanism in their tumor-preventive effects.

            effect of various avocado and soybean oils on collagen metabolism in the liver was studied in growing female
            rats for 8 weeks and in day-old chicks for 1 week. In comparison with rats fed either refined avocado oil,

            soluble collagen while hepatic total collagen remained unaffected. Electron micrographs and light-microscope

                vegetables, are in debate as human carcinogens. We screened a variety of vegetables (cabbage lettuce,
                beans, peas), some herbs and herbal-flavoured liquors for their content of the 'free' anthraquinones
                emodin, chrysophanol and physcion. For qualitative and quantitative analysis, reversed-phase HPLC
                (RP-LC), gas chromatography-mass spectrometry (GC-MS) and RP-LC-MS were used. The vegetables showed a
                large batch-to-batch variability, from 0.04 to 3.6, 5.9 and 36 mg total anthraquinone per kg fresh
                weight in peas, cabbage lettuce, and beans,</strong>
            respectively. Physcion predominated in all vegetables. <strong>In the herbs grape vine leaves, couch grass
                root and plantain herb, anthraquinones were above the limit of detection. Contents ranged below 1
                mg/kg</strong> (dry weight). All three anthraquinones were also found in seven of 11 herbal-flavoured
            liquors, in a range of 0.05 mg/kg to 7.6 mg/kg. The genotoxicity of the analysed anthraquinones was
            investigated in the comet assay, the micronucleus test and the mutation assay in mouse lymphoma L5178Y
            tk+/-<strong>
                cells. Emodin was genotoxic, whereas chrysophanol and physcion showed no effects. Complete vegetable
                extract on its own did not show any effect in the micronucleus test. A lettuce extract completely
                abolished the induction of micronuclei by the genotoxic anthraquinone danthron. Taking into
                consideration</strong> the measured concentrations of anthraquinones, estimated daily intakes, the
            genotoxic potency, as well as protective effects of the food matrix, the analysed constituents do not
            represent a high priority genotoxic risk in a balanced human diet.

                commonly consumed by nursing Congolese women: incidences on their essential fatty acid intakes and
                breast milk fatty acids.</strong>
            Rocquelin G, Tapsoba S, Mbemba F, Gallon G, Picq C Tropical Nutrition Unit, ORSTOM, Montpellier, France. The
            fat content and fatty acid (FA) composition of nearly 40 foods, currently consumed by 102 nursing Congolese
            mothers living in Brazzaville, were determined to assess their impact on mothers' essential fatty acid (EFA)
            intakes and breast milk FA. Data on mothers' milk FA and dietary habits which allowed food selection were
            recently published (Rocquelin et al., 1998). Most foods were locally produced. Food samples were collected
            at local markets, bleached if necessary to avoid microbial degradation, and stored at +4 degrees C or -20
            degrees C. They were lyophilized upon their arrival in the laboratory before lipid analyses. FA composition
            of food lipids was determined by capillary gas chromatography. Staple diets included low-fat,
            high-carbohydrate foods (processed cassava roots, wheat bread) and high-polyunsaturated fatty acid (PUFA)
            foods: soybean oil (high in 18 : 2 n-6 and alpha-18 : 3 n-3), bushbutter<strong>
                (dacryodes edulis), peanuts, avocado (high in fat and 18 : 2 n-6), freshwater</strong>
            and salt-water fish (high in LC n-3 and/or n-6 PUFA), and leafy green vegetables<strong>
                (low in fat but very high in alpha-18 : 3 n-3). Their frequent consumption by</strong> nursing mothers
            provided enough EFA to meet requirements due to lactation. It<strong>
                also explains why mothers' breast milk was rich in C8-C14 saturated FA (26% of</strong> total FA) and in
            n-6, n-3 PUFA (respectively 15.0% and 2.4% of total FA) highly profitable for breastfed infants'
            development. From this point of view, dietary habits of Congolese mothers have to be sustained for they are
            more adequate than most Western-type diets.

                Dietary carcinogens, environmental pollution, and cancer: some misconceptions.</strong> Ames BN, Gold LS
            Division of Biochemistry and Molecular Biology, University of California, Berkeley 94720. Various
            misconceptions about dietary carcinogens, pesticide residues, and cancer<strong>
                causation are discussed. The pesticides in our diet are 99.99% natural, since plants make an enormous
                variety of toxins against fungi, insects, and animal predators. Although only 50 of these natural
                pesticides have been tested in</strong> animal cancer tests, about half of them are carcinogens. About
            half of all chemicals tested in animal cancer tests are positive. The proportion of natural pesticides
            positive in animal tests of clastogenicity is also the same as for synthetic chemicals. It is argued that
            testing chemicals in animals at the maximum tolerated dose primarily measures chronic cell proliferation, a
            threshold process. Cell proliferation is mutagenic in several ways, including inducing mitotic
            recombination, and therefore chronic induction of cell proliferation is a risk factor for cancer.

            substances in the plant kingdom and in man's diet occur as glycosides. Recent studies have indicated that
            many glycosides that are not mutagenic in tests such as the Salmonella test become mutagenic upon hydrolysis
            of the glycosidic linkages. The Salmonella test utilizes a liver homogenate to approximate mammalian
            metabolism but does not provide a source of the enzymes present in intestinal bacterial flora that hydrolyze
            the wide variety of glycosides present in nature. We describe a stable cell-free extract of human feces,
            fecalase, which is shown to contain various glycosidases that allow the in vitro activation of many natural
            glycosides to mutagens in the Salmonella/liver homogenate test. Many beverages, such as red wine (but
            apparently not white wine) and tea, contain glycosides of the mutagne quercetin. Red wine, red grape juice,
            and tea were mutagenic in the test when fecalase was added, and red wine contained considerable direct
            mutagenic activity in the absence of fecalase. The implications of quercetin mutagenicity and
            carcinogenicity are discussed.

            Contaminated soils can be a source for crop plants of such elements like As, Cd, Cr, Cu, Ni, Pb, and Zn. The
            excessive transfer of As, Cu, Ni, and Zn to the food chain is controlled by a "soil-plant barrier"; <strong
            >however, for some elements, including Cd, the soil-plant barrier fails.</strong> The level of Cd ingested
            by average person in USA is about 12 micrograms/day, which is relatively low comparing to Risk Reference
            Dose (70 micrograms Cd/day) established by USEPA. <strong>Food of plant origin is a main source of Cd intake
                by modern society.</strong> Fish and shellfish may be a dominant dietary sources of Hg for some human
            populations. <strong>About half of human Pb intake is through food, of which more than half originates from
                plants.</strong>

            Dietary intake of Cd and Pb may be increased by application of sludges on cropland with already high levels
            of these metals. Soils amended with sludges in the USA <strong>will be permitted (by USEPA-503 regulations)
                to accumulate Cr, Cd, Cu, Pb, Hg, Ni, and Se, and Zn to levels from 10 to 100 times the present baseline
                concentrations.</strong>
            These levels are very permissive by international standards. Because of the limited supply of toxicity data
            obtained from metals applied in sewage sludge, predictions as to the new regulations will protect crop
            plants from metal toxicities, and food chain from contamination, are difficult to make.

                hypospadias. The ALSPAC Study Team. Avon Longitudinal Study of Pregnancy and Childhood.</strong>
            North K, Golding J Unit of Paediatric and Perinatal Epidemiology, Division of Child Health, University of
            Bristol, UK. OBJECTIVE: To investigate the possible role of the maternal diet, particularly vegetarianism
            and consumption of phytoestrogens, in the origin of hypospadias, which is reported to be increasing in
            prevalence. SUBJECTS AND METHODS: Detailed information was obtained prospectively from mothers, including
            previous obstetric history, lifestyle and dietary practices, using structured self-completed questionnaires
            during pregnancy. Previously recognized associations with environmental and parental factors were examined,
            focusing particularly on the hypothesized hormonal link. Multivariate logistic regression was used to
            identify independent associations. RESULTS: Of 7928 boys born to mothers taking part in the Avon
            Longitudinal Study of Pregnancy and Childhood, 51 hypospadias cases were identified. There were no
            significant differences in the proportion of hypospadias cases among mothers who smoked, consumed alcohol or
            for any aspect of their previous reproductive history (including the number of previous pregnancies, number
            of miscarriages, use of the contraceptive pill, time to conception and age at menarche). <strong>Significant
                differences were detected for some aspects of the maternal diet, i.e. vegetarianism and iron
                supplementation in the first half of pregnancy. Mothers who were vegetarian in pregnancy had an adjusted
                odds ratio (OR) of 4.99 (95% confidence interval, CI, 2.10-11.88) of giving birth to a boy with
                hypospadias, compared with omnivores who did not supplement their diet with iron. Omnivores who
                supplemented their diet with iron had an adjusted OR of 2.07 (</strong>95% CI, 1.00-4.32). The only
            other statistically significant association for hypospadias was with influenza in the first 3 months of
            pregnancy (adjusted OR 3.19, 95% CI 1.50-6.78). CONCLUSION: As vegetarians have a greater exposure to
            phytoestrogens than do omnivores, these results support the possibility that phytoestrogens have a
            deleterious effect on the developing male reproductive system.

            Vitamin E: Estrogen antagonist, energy promoter, and anti-inflammatory
        </h1>

        <em><p>
                Vitamin E, like progesterone and aspirin, acts within the cellular regulatory systems, to prevent
                inflammation and inappropriate excitation. Since uncontrolled excitation causes destructive oxidations,
                these substances prevent those forms of oxidation.
            </p>
            <p>
                Molecules that can easily be oxidized and reduced can function as antioxidants, and vitamin E does
                function as that kind of antioxidant in many chemical environments. But it is highly misleading to
                consider that as the explanation for its many beneficial biological effects. That kind of reasoning
                contributed to the use of the antioxidant carcinogens BHT and BHA as food additives and "antiaging"
                supplements, and many other chemicals are being promoted on the basis of their abstract antioxidant
                function.
            </p>
            <p>
                Becoming aware of the real value of vitamin E will have far reaching implications in nutrition and
                medicine.

                In determining criminal or civil legal responsibility, the concept "should have known" is recognized and
                used. In science, which is all about knowing, there is certainly a responsibility to be informed when
                the subject involves the life and health of millions of people. The science establishment of government
                and industry should be held responsible for the information it hides, destroys, or ignores for its own
                benefit. The US government has an agency for prosecuting research fraud, but the concept is applied so
                narrowly as to be meaningless, when deception has become the rule. And since it controls the court
                system, govenment agencies and their functionaries won't be prosecuted, even when their crimes become
                well known.

            Political scientists have recognized the process in which big corporations "capture" the governmental
            agencies that were created to regulate them. The editorial boards of professional journals can be captured
            even more cheaply than the agencies of government, and their influence can be even more valuable to
            industry.

            If science impinges upon the plans of an industry, it can be managed into compliance, when the industry

            In the 1940s, it had already become clear to the estrogen industry that vitamin E research was impinging on
            its vital interests.
        </p>
        <p>
            The Manhattan Project, that created the atomic bomb, also created a generation of scientific and
            bureaucratic zealots who ignored public health and safety to advance their projects and their careers, and
            changed the way science was done. At exactly the same time, the pharmaceutical industry was using its
            financial and political power to change the way medicine was practiced and taught, and the consequences for
            world health rivalled those of the nuclear industry.
        </p>
        <p>
            In 1933 the physician R.J. Shute was aware of the problems associated with toxemia of pregnancy or
            preeclampsia. Especially among poorly nourished women, many pregnancies were complicated by circulatory
            problems, including cyclic bleeding, thrombosis, stroke, and hypertension, and these difficult pregnancies
            often ended in miscarriage or premature delivery, resulting in many serious health problems among the babies
            that survived.
        </p>
        <p>
            At that time, both estrogen and vitamin E were being widely studied, though the exact structure of the
            tocopherol molecule wasn't defined until 1936-37. Vitamin E had been found to improve fertility of both male
            and female animals, and to prevent intrauterine death of the embryo or fetus, so it was called the
            "antisterility vitamin." Using it to prevent women from having miscarriages must have occurred to many
            people.
        </p>

        <p>
            Animal research in the 1930s was also showing that estrogen had many toxic effects, including causing
            infertility or intrauterine death, connective tissue abnormalities, and excessive blood clotting. Dr. Shute
            and his sons, Wilfred and Evan, were among those who considered vitamin E to be an antiestrogen. They found
            that it was very effective in preventing the clotting diseases of pregnancy.
        </p>
        <p>
            Other researchers, who knew that progesterone protected against the toxic effects of estrogen, described
            vitamin E as the "progesterone-sparing agent," since so many of its antiestrogenic effects resembled those

            The Shute brothers began using vitamin E to treat circulatory diseases in general, rather than just in
            pregnant women--blood clots, phlebitis, hypertension, heart disease, and diabetes all responded well to
            treatment with large doses.
        </p>
        <p>
            Vitamin E, as its name indicates, was the fifth type of "vitamin" factor to be identified, and it received
            its name in 1922, even though its chemical structure hadn't been identified. The public quickly understood
            and accepted that certain substances in food were essential for life and health, so by 1940 practically all
            physicians were recommending the use of nutritional supplements.
        </p>

        <p>
            If vitamin E was essential for human health, and achieved at least some of its amazing effects by opposing
            estrogen, then the synthetic estrogen industry had a problem.

            Edward L. Bernays had already been in business for decades, teaching corporations and governments how to
            "engineer consent." After his work for the government to engineer support for entering the first world war,
            Bernays' next big job was for the tobacco industry. To convince women to smoke cigarettes, to achieve
            equality with men, he organized an Easter parade, Torches of Freedom, in which thousands of women marched
            smoking their freedom torches. In association with the American Medical Association (the editor of JAMA
            actually helped the tobacco industry design its campaigns), Bernays ran a campaign to convince Americans
            that smoking was good for the health.

            The drug industry began using his techniques in sometimes crude but always effective ways. Estrogen was
            named "the female hormone;" natural hormones, including estrogen and progesterone, were claimed, without any
            research, to be inactive when taken orally. Physician-shills were created to claim wonderful effects for
            estrogen. The vitamin status of the tocopherols was denied; as recently as the 1970s (and maybe later),
            university professors of dietetics were flatly saying "no one needs vitamin E."
        </p>

        <p>
            Very little research showing the curative effects of vitamin E in human diseases was allowed to be
            published, so it was only occasionally necessary to openly denounce vitamin E as worthless or dangerous. In
            1981, the journal of the AMA published an article reviewing the "toxic" effects of vitamin E. Since I had
            read all of the articles cited, I realized that the author was claiming that whenever vitamin E changed
            something, the change was harmful, even though the original publication had described the effect as
            beneficial.
        </p>
        <p>
            Although JAMA was eventually forced to give up its revenue from cigarette advertising, it didn't suffer at
            all, because of the vast advertising campaigns of the estrogen industry. JAMA obviously wouldn't want to
            publish anything suggesting that vitamin E, or progesterone, or thyroid, might be beneficial because of its
            antagonism of the harmful effects of estrogen.

            Estrogen causes changes in the uterus that prevent implantation of the embryo, and that impair support for
            its development if it has already implanted. It decreases the availability of oxygen to the embryo, while
            vitamin E increases it.
        </p>
        <p>
            My dissertation adviser, A.L. Soderwall, did a series of experiments in which he showed that providing
            hamsters with extra vitamin E postponed the onset of infertility in middle age. In my experiments, vitamin E
            increased the amount of oxygen in the uterus, correcting an oxygen deficiency produced either by
            supplemental estrogen or by old age. Progesterone has similar effects on the delivery of oxygen to the
            uterus.
        </p>
        <p>
            In the 1940s, the official definition of vitamin E's activity was changed. Instead of its effectiveness in
            preventing the death and resorption of embryos, or the degeneration of the testicles or brain or muscles, it
            was redefined as an antioxidant, preventing the oxidation of unsaturated oils.
        </p>

        <p>
            Although some people continued to think of it as a protective factor against thrombosis, heart attacks,
            diabetes, and infertility, the medical establishment claimed that the prevention or cure of diseases in
            animals wasn't relevant to humans, and that a mere antioxidant couldn't prevent or cure any human disease.
        </p>
        <p>
            The experiments that led to the identification of vitamin E involved feeding rats a diet containing rancid
            lard and, as a vitamin A supplement, cod liver oil. Both of these contained large amounts of polyunsaturated
            oils.
        </p>
        <p>
            From 1929 to the early 1930s, other researchers were claiming to have demonstrated that the polyunsaturated
            fatty acids were nutritionally essential. These experiments, like the vitamin E experiments, were done on
            rats, but the medical establishment was satisfied that rat experiments proved that humans need linoleic or
            linolenic acid, while they refused to accept that vitamin E was essential for humans. When, in the 1940s, a
            group of vitamin B6 researchers showed that the supposed "essential fatty acid deficiency" could be cured by
            a supplement of vitamin B6, it became apparent that the polyunsaturated fatty acids slowed metabolism, and
            reduced all nutritional needs. The thyroid hormone was powerfully suppressed by the "essential" fatty acids.
        </p>
        <p>
            When we consider the two sets of experiments together, their outstanding feature is the toxicity of the
            polyunsaturated oils, which in one kind of experiment suppressed metabolism, and in the other kind of
            experiment created a variety of degenerative conditions.
        </p>

        <p>
            By the late 1940s and early 1950s, estrogens of various sorts had been synthesized from hydrocarbons, and
            were being recommended to prevent miscarriages, because "estrogen is the female hormone." The meat industry
            had found that the polyunsaturated oils were valuable in animal feed, since they suppressed metabolism and
            made it cheaper to fatten the animals, and these antithyroid oils were next marketed as "heart protective"
            human foods, though by suppressing the thyroid and destroying vitamin E, they actually contributed to both
            heart disease and cancer. (Giving estrogen to livestock to improve their feed efficiency, and to people "to
            prevent heart attacks," was an interesting parallel to the oil promotional campaigns.)
        </p>
        <p>
            The influence of the food oil industry kept researchers away from the idea that these oils were not safe for
            food use, and instead tended to support the idea that vitamin E is just an antioxidant, and that the seed
            oils were the best way to get vitamin E in the diet.
        </p>
        <p>
            The antifertility effects of the polyunsaturated oils, demonstrated in the vitamin E experiments, weren't at
            the time understood to have anything to do with estrogen's antifertility effects. But to understand vitamin
            E, I think we have to consider the close interactions between estrogen and the polyunsatured fatty acids
            (PUFA). Their actions are closely intertwined, and are antagonized by a variety of energizing and
            stabiliizing substances, including saturated fats, progesterone, thyroid, vitamin E, and aspirin.
        </p>

        <p>
            Generally, chemicals that inhibit enzymes are toxic, producing some sort of symptom or deterioration. But a
            group of enzymes related to estrogen and PUFA are inhibited by these protective substances. Although under
            our present diet, these enzymes metabolize the PUFA, in the fetus and newborn they act on our endogenous
            fats, the series related to the Mead acids. The Mead acid is antiinflammatory, and broadly protective. The
            dietary PUFA interfere with these natural protective substances,
        </p>
        <p>
            The enzymes that, if we didn"t eat PUFA, would be regulating the Mead series, being activated in response to
            stress, would be producing antistress substances, which would limit the stress reaction. But as we become
            increasingly saturated with the anti-vitamin E fats, these enzymes, instead of stopping inflammation,
            promote it and cause tissue injury. The remaining stress limiting factors, such as progesterone, by
            correcting the distortions caused by stress, tend to eliminate the conditions which activated the
            enzymes--in a very indirect form of inhibition.
        </p>
        <p>
            Many of the events involved in inflammation are increased by estrogen, and decreased by vitamin E. Estrogen
            causes capillaries to become leaky; vitamin E does the opposite. Estrogen increases platelet aggregation,
            and decreases a factor that inhibits platelet aggregation; vitamin E does the opposite.
        </p>
        <p>
            Excess clotting is known to be caused by too much estrogen, and also by a vitamin E deficiency.
        </p>
        <p>
            Clotting leads to fibrosis, and there is clear evidence that vitamin E prevents and cures fibrotic diseases,
            but this still isn't generally accepted by the powerful medical institutions. Estrogen and polyunsaturated
            fats increase fibrosis.
        </p>
        <p>
            Estrogen increases progstaglandin synthesis, vitamin E decreases their synthesis; estrogen increases the
            activity of the enzymes COX and LOX, vitamin E decreases their activitiy. (Jiang, et al., 2000; Ali, et al.,
            1980; Parkhomets, et al., 2001.) Estrogen releases enzymes from lysosomes, vitamin E inhibits their release.
            Beta-glucuronidase, one of these enzymes, can release estrogen at the site of an inflammation.
        </p>

        <p>
            Estrogen often increases intracellular calcium and protein kinase C, vitamin E has generally opposite
            effects.
        </p>
        <p>
            The polyunsaturated fatty acids and their derivatives, the prostaglandins, act as effectors, or amplifiers,
            of estrogen's actions.
        </p>
        <p>
            If vitamin E is acting as a protectant against the polyunsaturated fatty acids, that in itself would account
            for at least some of its antiestrogenic effects.
        </p>
        <p>
            Besides antagonizing some of the end effects of the toxic fatty acids, vitamin E inhibits lipolysis,
            lowering the concentration of free fatty acids (the opposite of estrogen"s effect), and it also binds to,
            and inactivates, free fatty acids. The long saturated carbon chain is very important for its full
            functioning, and this saturated chain might allow it to serve as a substitute for the omega -9 fats, from
            which the Mead acid is formed. The unsaturated tocotrienols have hardly been tested for the spectrum of true
            vitamin E activity, and animal studies have suggested that it may be toxic, since it caused liver
            enlargement.
        </p>
        <p>
            One possibly crucial protective effect of vitamin E against the polyunsaturated fatty acids that hasn't been
            explored is the direct destruction of linolenic and linoleic acid. It is known that <strong>bacterial
                vitamin E is involved in the saturation of unsaturated fatty acids, and it is also known that intestinal
                bacteria turn linoleic and linolenic acids into the fully saturated stearic acid.</strong>

        <p>
            Because of the way in which the decision to call vitamin E a simple antioxidant was conditioned by the
            historical setting, there has been a reluctance, until recently, to give much weight to the pathogenicity of
            lipid peroxidation and free radicals, partly because lipid peroxidation is only a minor part of the toxicity
            of the polyunsaturated oils, and there was little support for the investigation of the real nature of their
            toxicity. This environment has even distorted the actual antioxidant value of the various forms of vitamin
            E. (For example, see Chen, et al., 2002.)
        </p>
        <p>
            The people who say that vitamin E is nothing but an antioxidant sometimes take other antioxidants, with, or
            instead of, vitamin E. BHT, BHA, and many natural compounds (derived from industrial and agricultural
            wastes) are often said to be "better than vitamin E" as antioxidants. Anything that can be oxidized and
            reduced (melatonin, estrogen, tryptophan, carotene, etc.) will function as an antioxidant in some system,
            but in other circumstances, it can be a pro-oxidant.
        </p>
        <p>
            The people who think there is benefit in the abstract "antioxidant" function seem to be thinking in terms of
            something that will, like a ubiquitous fire department, put out every little fire as soon as it starts. I
            think it's more appropriate to think of the biological antioxidant systems as programs for controlling the
            arsonists before they can set the fires.
        </p>
        <p>
            Since the requirement for vitamin E decreases as the consumption of unsaturated fats decreases, the
            requirement, if any, would be very small if we didn't eat significant quantities of those fats.
        </p>

        <p>
            In the years since the tocopherols were identified as vitamin E, the material sold for research and for use
            as a nutritional supplement has changed drastically several times, even when it has been given a specific
            chemical identity, such as mixed tocopherols or d-alpha tocopherol. Variations in viscosity and color,
            caused by changes in the impurities, have undoubtedly influenced its biological effects, but the ideology
            about its antioxidant value has kept researchers from finding out what a particular batch of it really is
            and what it really does.
        </p>

            <strong>"We compared the effect of a mixed tocopherol preparation with that of alpha-tocopherol alone on

            Keeping our diet as free as possible of the polyunsaturated fats, to create something like the "deficiency"
            state that is so protective (against cancer, trauma, poison, shock, inflammation, infection, etc.) in the
            animal experiments, seems preferable to trying to saturate ourselves with antioxidants, considering the
            imperfectly defined nature of the vitamin E products, and the known toxicity of many of the other
            antioxidants on the market.
        </p>

        <p>
            The carcinogenic properties of the polyunsaturated fats have been known for more than 50 years, as has the
            principle of extending the life span by restricted feeding. More recently several studies have demonstrated
            that the long lived species contain fewer highly unsaturated fats than the short lived species. <strong
            >Restriction of calories prevents the lipids in the brain, heart, and liver from becoming more unsaturated
                with aging.</strong>
            (Lee, et al., 1999; Laganiere, et al., 1993; Tacconi, et al., 1991; R. Patzelt-Wenczler, 1981.)
        </p>
        <p>
            When cells are grown in tissue culture without the "essential fatty acids," they become "deficient," and in
            that state are very resistant to chemical injury, and can be grown indefinitely. Besides being a simple
            demonstration of the way in which the polyunsaturated fats sensitize cells to injury (Wey, et al., 1993),
            these experiments must be an embarrassment to the people who base their argument for the oils" essentiality
            on a supposed requirement for "making cell membranes." Since the cells can multiply nicely in their
            deficient state, we have to conclude that the oils aren"t needed for "membranes," or maybe that cells resist
            injury better "without membranes."
        </p>
        <p>
            In the opposite direction, an excess of insulin or prolactin, or a deficiency of vitamin E, increases the
            activity of the enzymes that convert linoleic acid into the more highly unsaturated fatty acids. Excess
            insulin and prolactin are crucially involved in many degenerative diseases.
        </p>
        <p>
            The highly unsaturated fats suppress respiration in many ways, and these trends toward increased
            unsaturation with aging, endocrine stress, and vitamin E deficiency parallel the life-long trend toward
            lower energy production from respiration. Many studies show that vitamin E can protect and improve
            mitochondrial energy production. (Kikuchi, et al., 1991; Donchenko, et al., 1990, 1983; Guarnieri, et al.,
            1981, 1982.) But the state of so-called essential fatty acid deficiency not only makes mitochondria very
            resistant to injury, it greatly intensifies their energy production. Vitamin E supplementation is seldom as
            effective as the absence of the toxic oils.
        </p>
        <p>
            Many nutrition charts no longer list liver as a good source of vitamin E, but a large portion of an animal"s
            vitamin E is in its liver. This bias in the dietetic literature can be traced to various sources, but a
            major influence was the campaign in the 1970s by the drug companies that had patented new forms of synthetic
            "vitamin A." They had physicians and professors fabricate stories about the great toxicity of natural
            vitamin A, and placed the stories in national magazines, to clear the field for their supposedly non-toxic
            products, which have turned out to be disastrously toxic. The result is that many people have fearfully
            stopped eating liver, because of its vitamin A. The other vitamins in liver, including vitamin K, function
            very closely with vitamin E, and the stably stored forms of vitamin E are likely to be a good approximation
            for our needs.
        </p>

        <p>
            There is still a strong division between what people can say in their professional publications, and what
            they believe. A man who was influential in designating vitamin E as an antioxidant, M.K. Horwitt, complained
            when the government raised its recommended vitamin E intake by 50%, because it wasn"t supported by new data,
            and because millions of people get only ten milligrams per day and "are healthy." But he has been taking 200
            mg daily (plus aspirin) for many years. He apparently doesn't have very much confidence in the ideas he
            advocates publicly.

            contractures following breast augmentation. The synthetic form of vitamin E (alpha-tocopherol) is
            recommended to avoid nausea or skin eruptions in patients with oily skin, which are frequently encountered
            when the natural form is taken. No harmful side effects have been noted in any of the patients to date.
            Vitamin E has no effect on coagulation systems and does not cause excessive bleeding either during or after
            surgery. The recommended dosage of synthetic vitamin E is 1000 IU, b.i.d., for 2 years beginning 1 week
            before surgery. If no contracture exists at that time, the dosage may be reduced to 1000 IU daily
            thereafter.

            about the influence of food restriction on brain lipids, whose concentration and composition have been shown
            to change with age. We studied whether some biochemical and biophysical parameters of rat brain membranes,
            known to be modified with age, were affected by a diet low in calories, in which 50% of lipids and 35% of
            carbohydrates have been replaced by fibers. The diet was started at weaning and maintained throughout the
            animal's entire life span. Animals fed the low calorie diet survived longer and gained less body weight than
            standard diet fed rats. Age-related increases in microviscosity, cholesterol/phospholipid and
            sphingomyelin/phosphatidylcholine ratios were <strong>reduced or restored to the levels of young animals in
                cortex membranes of 32 old rats fed the low calorie diet, while the age-related increase in mono- to
                polyunsaturated fatty acid ratios in phospholipids was further raised.</strong> In conclusion we have
            shown that a diet low in calories and high in fibers affects lipid composition in the rat brain, <strong>in
                a direction opposite to that normally believed to reduce age-related deterioration of brain
                functions</strong>.

                keratinocytes attenuates toxicity due to lipid peroxidation.</strong> Wey HE, Pyron L,<strong>
                Human keratinocytes are commonly grown in culture with a serum-free medium. Under these conditions,
                keratinocytes become essential fatty acid deficient (EFAD), as determined by gas chromatographic
                analysis of cell phospholipid fatty acid composition. Exposure of EFAD keratinocytes for 2 hr to
                concentrations of t-butyl hydroperoxide (tBHP) up to 2 mM did not result in toxicity assessed by lactate
                dehydrogenase (LDH) release and only a small indication of lipid peroxidation assessed by the release of
                thiobarbituric acid-reactive substances</strong> (TBARS). Addition of 10 microM linoleic acid (LA) to
            serum-free medium alleviated the EFAD condition by increasing the phospholipid content of LA and its
            elongation and desaturation products, arachidonic acid and docosatetraenoic acid. Exposure of
            LA-supplemented keratinocytes to tBHP resulted in significant LDH (at 1 and 2 mM tBHP) and TBARS (tBHP
            concentration dependent) release. TBARS release was also significantly elevated in unexposed LA-supplemented
            keratinocytes (basal release). Co-supplementation with the antioxidant,<strong>
                alpha-tocopherol succinate (TS) prevented tBHP (1 mM)-induced LDH release in LA-supplemented cultures.
                TS supplementation also attenuated the effect of tBHP on TBARS release, but when compared to
                TS-supplemented EFAD cultures, LA</strong> supplementation still led to increased tBHP-induced TBARS
            release. Keratinocyte cultures are potentially useful as an alternative to animals in toxicology research
            and testing. It is important, however, that the cell model provide a response to toxic insult similar to
            that experienced in vivo. Our results suggest that fatty acid and antioxidant nutrition of cultured
            keratinocytes are important parameters in mediating the toxic effects of lipid peroxidation.

        "The response-to-injury hypothesis explains atherosclerosis as a chronic inflammatory response to injury of the
        endothelium, which leads to complex cellular and molecular interactions among cells derived from the
        endothelium, smooth muscle and several blood cell components. Inflammatory and other stimuli trigger an
        overproduction of free radicals, which promote peroxidation of lipids in LDL trapped in the subendothelial
        space. Products of LDL oxidation are bioactive, and they induce endothelial expression and secretion of
        cytokines, growth factors and several cell surface adhesion molecules. The last-mentioned are capable of
        recruiting circulating monocytes and T lymphocytes into the intima where monocytes are differentiated into
        macrophages, the precursor of foam cells. In response to the growth factors and cytokines, smooth muscle cells
        proliferate in the intima, resulting in the narrowing of the lumen. Oxidized LDL can also inhibit endothelial
        production of prostacyclin and nitric oxide, two potent autacoids that are vasodilators and inhibitors of
        platelet aggregation. Evidence is presented that vitamin E is protective against the development of
        atherosclerosis. Vitamin E enrichment has been shown to retard LDL oxidation, inhibit the proliferation of
        smooth muscle cells, inhibit platelet adhesion and aggregation, inhibit the expression and function of adhesion
        molecules, attenuate the synthesis of leukotrienes and potentiate the release of prostacyclin through
        up-regulating the expression of cytosolic phospholipase A2 and cyclooxygenase. Collectively, these biological
        functions of vitamin E may account for its protection against the development of atherosclerosis."

            relationships with anthropometric measurements at birth. Ghebremeskel K, Burns L, Burden TJ, Harbige L,
            Costeloe K, Powell JJ, Crawford M. Institute of Brain Chemistry and Human Nutrition, Queen Elizabeth
            Hospital for Children, London, UK. Following the advice given by the Department of Health to women who are,
            or may become pregnant, not to eat liver and liver products because of the risk of vitamin A toxicity, the
            concentrations of vitamins A and E, and copper, magnesium and zinc in cord blood were investigated. The
            study was conducted in Hackney, an inner city area of London. Esters of vitamin A were not detected in any
            of the samples, indicating that there was no biochemical evidence of a risk of toxicity. Indeed, vitamin A
            correlated significantly with birthweight, head circumference, length, and gestation period. There was also
            a significant positive relationship between zinc and birthweight. In contrast, copper showed a negative
            correlation with birthweight and head circumference. Vitamin E and magnesium were not associated with any of
            the anthropometric measurements, although magnesium showed an increasing trend with birthweight. The data
            suggest that most of the mothers of the subjects studied may have been marginal with respect to vitamins A
            and E and zinc. In those with low birthweight babies. a higher intake would have improved their nutritional
            status and possibly the outcome of their pregnancy. For these low-income mothers, liver and liver products
            are the cheapest and the best source of vitamins A and E, haem iron, B vitamins and several other essential
            nutrients; hence the advice of the Department of Health may have been misplaced.

            Water: swelling, tension, pain, fatigue, aging
        </h1>

        <p>
            I have spoken to many people who believe they should drink "8 glasses of water every day," in addition to
            their normal foods, even if they don't feel thirsty. Many doctors still recite this dangerous slogan, but
            the addition of the qualifying phrase, "or other liquids," has become common.
        </p>
        <p>
            The amount of water a person needs is extremely variable, depending on things such as metabolic rate,
            activity, and the temperature and humidity of the air. Working hard in hot, dry weather, it's possible to
            drink more than two quarts per hour for more than eight hours, without forming any urine, because all of the
            water is lost by evaporation. But in very hot, humid weather, a person with a low metabolic rate can be
            endangered by the smallest amount of water (e.g., "Meteorological relations of eclampsia in Lagos, Nigeria,"
            Agobe, et al., 1981).
        </p>
        <p>
            Most foods contain a considerable amount of water, usually more than 70% of their weight, and some water is
            produced in cells by metabolism. The function of water in the organism has been mystified and neglected
            because of some deeply rooted cultural images of the nature of organisms and their cellular make-up.
        </p>
        <p>
            One silly image that has been perpetuated by schools and textbooks is that biochemistry consists of chemical
            reactions that occur in substances dissolved in water, and that the water is retained by cells because they
            are enclosed by an oily membrane, and because of the osmotic forces produced by the dissolved substances.
            Most grade school kids have seen an osmometer made from an egg, in which the egg causes a column of water to
            rise, and have heard the explanation that this has something to do with the way cells work. Membrane pumps
            are invoked to explain the differences in solute concentrations and "osmotic pressure" inside and outside
            cells. The story is that invisible things on the surface of a cell (in its "membrane") force dissolved
            molecules to move in ways that they wouldn't move spontaneously by diffusion, and that water passively
            follows the "actively transported" solutes. But the evidence shows that both water and its solutes are
            regulated by the bulk phase of the cell, not its surface.
        </p>

        <p>
            In some cultural settings, animism has a kind of charm (water sprites, and such), but in the culture of
            medicine and biology, the animistic conceptualization of cells and their mechanisms has been very
            destructive, because it gets in the way of coherent understanding of physiology. Practically every disease
            would be approached differently if the physiology of water and ions were allowed to advance beyond the
            animistic doctrines of mainstream medicine, such as the "membrane pumps." If all the substances that are
            said to be "actively transported" by pumps into, or out of, cells are considered, the amount of energy
            required to operate the pumps is at least 15 times larger than the total energy available to cells.
            "Specific" pumps are commonly invoked even for novel synthetic chemicals, to explain their unequal
            distribution, inside and outside cells. In many biological situations water is ignored, but when it becomes
            an issue, its distribution is usually mechanistically subordinated to the solutes that are actively
            "pumped."
        </p>
        <p>
            Cells aren't osmometers, in the sense the textbooks say. They do control their water content, but no
            "membrane pumps" are needed. It's more accurate to think of the water of cells as being "dissolved in
            cells," somewhat the way water is contained in jello or boiled eggs. The cell controls its hydration by the
            processes that control its structure, its metabolism, and movements, because water is part of its deepest
            structures and essential functions. The cell's adjustments to changes of hydration and volume appear to be
            regulated by contractile proteins and energy metabolism (Minkoff and Damadian, 1976).
        </p>

        <p>
            Any stress or energy deficit that disturbs cellular structure or function disturbs the interactions among
            water, proteins, and other components of the cell. Excitation causes a cell to take up extra water, not by
            osmosis resulting from an increase in the concentration of solutes in the cell, or because the membrane has
            become porous, but because the structural proteins of the cell have momentarily increased their affinity for
            water.
        </p>
        <p>
            This increased affinity is similar to the process that causes a gel to swell in the presence of alkalinity,
            and it is related to the process called electroosmosis, in which water moves toward a higher negative
            charge. Intense excitation or stress increases the cell's electrically negative charges, and causes it to
            become more alkaline and to swell. Swelling and alkalinity cause the cell to begin the synthesis of DNA, in
            preparation for cell division. Mitogens and carcinogens, including estrogen, cause cells to become alkaline
            and to swell, and substances that block the cell's alkalinization (such as the diuretics acetazolamide and
            amiloride) inhibit cell division. Prolonged alkaline stress alone can cause malignant transformation of
            kidney cells (Oberleithner, et al., 1991).
        </p>
        <p>
            The general idea of "stress" is useful, because it includes processes such as fatigue, osmotic pressure
            changes, disturbed pH, and the enzyme changes that follow, producing substances such as lactic acid, nitric
            oxide, polyamines, estrogen, serotonin, and many more specific mediators. But paying attention to the
            physical factors involved in a stress reaction is important, if we are to see the organism integrally,
            rather than as a collection of "specific biological mechanisms," involving things like the pixie-powered
            "membrane pumps."
        </p>

        <p>
            When a cell shrinks under hyperosmolar conditions, its metabolism becomes catabolic, breaking down proteins
            and glycogen, and sometimes producing lactic acid, which results in an alkaline shift, increasing the cell's
            affinity for water, and causing it to return to normal size. A slight degree of hyperosmolarity increases
            the cell's metabolic rate.
        </p>
        <p>
            Swelling in hypo-osmolar conditions, i.e,, with an excess of water, is anabolic, leading to cellular
            proliferation, and inhibiting the breakdown of protein and glycogen.
        </p>
        <p>
            Respiring cells are always producing some water, by transferring hydrogen from fuel molecules to oxygen.
            Respiration also produces carbon dioxide, which in itself is a Lewis acid (meaning that it binds electrons,
            rather than releasing protons), that associates with cellular proteins, acidifying them in the process. A
            large amount of carbon dioxide can exist inside cells in the bound form. Acidified cytoplasm (like any other
            mostly acidic polymer-gel) releases water and sodium. (This process is physically analogous to the process
            of flushing a water softener with salt, or a demineralizer with acid, to reactivate it.)
        </p>
        <p>
            Besides binding with the cytoplasm, the carbon dioxide can be changed into carbonic acid, by chemically
            combining with water. Carbonic acid is hydrophilic, and so it quickly leaves the cell, taking with it some
            of the oppositely charged ions, such as calcium and sodium. The formation of carbonic acid, which is
            constantly streaming out of the respiring cell, causes some water and some positively ionized metals to
            leave the cell, in an "active" process, that doesn't require any mysterious pumps.
        </p>

        <p>
            As the blood passes through the lungs, carbon dioxide leaves the system, and as carbonic acid is converted
            to carbon dioxide, water is left behind in the blood, along with the counterions (of alkaline metals or
            earths), accounting for slight differences in pH and osmolarity between the bloodstream and the tissue
            cells. Some experiments suggest that the normal osmolarity of various tissues is 2 or 3 times higher than
            that of the blood, which is called "isosmolar" or isotonic.
        </p>
        <p>
            The kidneys adjust the osmolarity of the blood by allowing water and solutes to leave the bloodstream, in
            proportions that usually keep the body fluids in balance with cells. The kidneys are able to compensate for
            many of the imbalances produced by stress and inappropriate diets, for example by forming ammonia and carbon
            dioxide, to compensate for imbalances in the alkalis and acids that are being delivered to the blood by
            other organs. Because of the kidneys' great ability to regulate the flow of solutes between the blood and
            the forming urine, the "membrane pumps" have great importance for medical nephrologists. But the more
            extreme the "active transport" is, the more obvious it becomes that processes other than "membrane pumps"
            are responsible.
        </p>

        <p>
            Some lizards and sea birds have glands near their noses that are called salt glands, because of their
            ability to secrete salt. The salt gland is probably the most extreme case of active transport, but its
            physiology is very similar to the physiology of any other secretory gland or membrane, such as tear glands
            and sweat glands. The mechanism of salt excretion in these glands should really settle the issue of how
            active transport works, but most nephrologists, oculists, and medical researchers in general aren't
            interested in salt glands.
        </p>
        <p>
            Carbon dioxide is the driving force in the salt gland. The constant formation of CO2, and its loss into the
            air, allows a high concentration of salt to be excreted. Blocking the interchange of CO2 and carbonic acid,
            with acetazolamide, or inhibiting the formation of CO2, prevents the excretion of salt.
        </p>
        <p>
            Since respiratory metabolism, governed by the thyroid hormone, is our main source of carbon dioxide, it's
            obvious that thyroid deficiency should impair our ability to regulate water and solutes, such as salt. An
            organism that illustrates this function of thyroid is the young salmon, when it leaves a freshwater river to
            begin its life in the ocean. As it converts its physiology to tolerate the salty environment, its thyroid
            hormone surges. When it's mature, and returns to the fresh water to spawn, its prolactin rises sharply. In
            experiments with rodents, it has been found that drinking a large amount of water increases their prolactin,
            but the same amount of water, with added salt, doesn't.
        </p>
        <p>
            Hypothyroidism is typically associated with increased prolactin secretion. Hypothyroid people typically
            retain water, while losing salt, so the hypothyroid state is analogous to the salmon that has returned to
            the river, and to the mice that drink too much salt-free water.
        </p>
        <p>
            The typical hypothyroid person loses salt rapidly in the urine (and probably in the sweat, too, though that
            is usually diagnosed as cystic fibrosis), and retains water, diluting the urine less than normal. The
            reduced production of carbon dioxide, with increased susceptibility to producing lactate and ammonium,
            causes the cells to be more alkaline than normal, increasing their affinity for water. The rise of estrogen
            that usually accompanies hypothyroidism also increases intracellular pH, loss of sodium, and over-hydration
            of the blood.
        </p>

        <p>
            Hypothyroid muscles typically retain excess water, and fatigue easily, taking up more water than normal
            during exertion. In childhood, mild hypothyroidism often causes the leg muscles to swell and ache in the
            evenings, with what have been called "growing pains." When the problem is more extreme, all the skeletal
            muscles can become very large (Hoffman syndrome), because of the anabolic effect of over-hydration.
            Enlargement of any muscle can result from the excessive hydration produced by thyroid deficiency, but when
            it happens to the muscles behind the eyes (Itabashi, et al., 1988), it often leads to a diagnosis of
            hyperthyroidism, rather than hypothyroidism.
        </p>
        <p>
            The little kids with the Hoffman syndrome don't have the bloated myxedematous appearance that's often
            associated with hypothyroidism. They look athletic to a ridiculous degree, like miniature body-builders. But
            after a few weeks of treatment with thyroid, they regain the slender appearance that's normal for their age.
            The swollen state actually supports enlargement of the muscle, and the cellular processes are probably
            closely related to the muscle swelling and growth produced by exercise. The growth of the muscle cell during
            swelling seems to be the result of normal repair processes, in a context of reduced turnover of cellular
            proteins.
        </p>
        <p>
            The people who believe in membrane pumps that maintain normal solute distributions by active transport know
            that the pumps would require energy (far more than the cell can produce, but they don't confront that
            issue), and so their view requires that they assign a great part of the cell's resources just to maintaining
            ionic homeostasis, and the result of that is that they tend to neglect the actual energy economy of the
            cell, which is primarily devoted to the adaptive renewal of the cell structure and enzyme systems, not to
            driving the systems that don't exist.
        </p>

        <p>
            The "anabolic" balance of the swollen cell is the result of decreased turnover of the cell's components. The
            higher rate of metabolism produced by adequate thyroid function maintains a high rate of renewal of the
            cell's systems, keeping the cell constantly adjusted to slight changes in the organism's needs. The evidence
            of a high rate of bone turnover is sometimes taken as evidence that thyroid can cause osteoporosis.
        </p>
        <p>
            Later, in a more mature person, chronically fatigued and painful muscles that at one time would have been
            diagnosed as rheumatism, may be diagnosed as fibromyalgia. Most doctors are reluctant to prescribe thyroid
            supplements for the problem, but the association of elevated prolactin with the muscle disorder is now
            generally recognized.
        </p>
        <p>
            The hypo-osmolar blood of hypothyroidism, increasing the excitability of vascular endothelium and smooth
            muscle, is probably a mechanism contributing to the high blood pressure of hypothyroidism. The swelling
            produced in vascular endothelium by hypo-osmotic plasma causes these cells to take up fats, contributing to
            the development of atherosclerosis. The generalized leakiness affects all cells (see "Leakiness"
            newsletter), and can contribute to reduced blood volume, and problems such as orthostatic hypotension. The
            swollen endothelium is stickier, and this is suspected to support the metastasis of cancer cells.
            Inflammation-related proteins, including CRP, are increased by the hypothyroid hyperhydration. The heart
            muscle itself can swell, leading to congestive heart failure.
        </p>

        <p>
            Some of the nerve problems associated with hypothyroidism (e.g., carpal tunnel syndrome and "foot drop") are
            blamed on compression of the nerves, from swelling of surrounding tissues, but the evidence is clear that
            hypothyroidism causes swelling in the nerve cells themselves. For example, in hypothyroidism, nerves are
            slow to respond to stimulation, and their conduction of the impulse is slow. These changes are the same as
            those produced by hyper-hydration caused by other means. Hypothyroid nerves are easily fatigued, and
            fatigued nerves take up a large amount of water. Swelling of the spinal cord is probably responsible for the
            "spinal stenosis" commonly seen in domestic animals and people; the mobility of intracellular water
            molecules is distinctly increased in patients with compression of the spinal cord (Tsuchiya, et al., 2003;
            Ries, et al., 2001).
        </p>
        <p>
            The hyperhydration of hypothyroidism has been known to cause swelling and softening of cartilage, with
            deformation of joints, but somehow it has never dawned on surgeons that this process would lead to
            deformation of intervertebral disks.
        </p>
        <p>
            It has been known for a long time that hyperhydration can produce seizures<strong>;</strong>
            at one time, neurologists would test for epilepsy by having the patient drink a pint of water. Although
            there are many reasons to think that the hyperhydration produced by hypothyroidism is a factor in epilepsy,
            physicians have been very reluctant to consider the possibility, because they generally think of thyroid
            hormone as a stimulant, and believe that "stimulants" are necessarily inappropriate for people with
            epilepsy.
        </p>

        <p>
            While it's true that the thyroid hormone increases sensitivity to adrenaline, its most noticeable effect is
            in improving the ability to relax, including the ability to sleep soundly and restfully. And it happens that
            increasing norepinephrine (the brain's locally produced form of adrenaline) helps to prevent seizures
            (Giorgi, et al., 2004).
        </p>
        <p>
            Cell swelling increases the sensitivity of nerves, and hyperosmotic shrinkage lowers their sensitivity.
            Increasing carbon dioxide helps to reduce the hydration of tissue (for example, the hydration and thickness
            of the cornea are decreased when carbon dioxide is increased), and increasing carbon dioxide is known to
            inhibit epileptic seizures. Another diagnostic trick of neurologists was to have the patient hyperventilate;
            it would often bring on a seizure. The diuretic acetazolamide, which increases the body's carbon dioxide and
            reduces water retention, is very effective for preventing seizures.
        </p>
        <p>
            The sleep-inducing effect of salty food is probably related to the anti-excitatory effects of
            hyperosmolarity, of adequate thyroid function, and of carbon dioxide.
        </p>
        <p>
            Degenerative diseases, especially cancer, heart disease, and brain diseases, are less prevalent in
            populations that live at a high altitude. When oxygen pressure is low, the lungs lose carbon dioxide more
            slowly, and so the amount of carbon dioxide retained in the body is greater. If the basic problem in
            hypothyroidism is the deficient production of carbon dioxide causing excessive loss of salt and retention of
            water, resulting in hypo-osmotic body fluids, then we would expect people at high altitude to have better
            retention of salt, more loss of water, and more hypertonic body fluids. That has been observed in many
            studies. The increased rate of metabolism at altitude would be consistent with the relatively active
            "catabolism" of the slightly hyperosmotic condition.

            After the drug companies began, in the late 1950s, marketing some newly discovered (thiazide) diuretics,
            which cause sodium to be lost in the urine, their advertising campaigns created a cultish belief that salt
            caused hypertension. They convinced a whole generation of physicians that pregnant women should limit salt
            in their diet, take a diuretic preventively, and restrict calories to prevent "excessive" weight gain.
            Millions of women and their babies were harmed by that cult.
        </p>

            Pre-eclampsia and pregnancy toxemia have been corrected (Shanklin and Hodin, 1979) by both increased dietary
            protein and increased salt, which improve circulation, lower blood pressure, and prevent seizures, while
            reducing vascular leakiness. The effectiveness of increased salt in pre-eclampsia led me to suggest it for
            women with premenstrual edema, because both conditions typically involve high estrogen, hyponatremia, and a
            tendency toward hypo-osmolarity. Estrogen itself causes sodium loss, reduced osmolarity, and increased
            capillary leakiness. Combined with a high protein diet, eating a little extra salt usually helps to correct
            a variety of problems involving edema, poor circulation, and high blood pressure.
        </p>
        <p>
            The danger of salt restriction in pregnancy has hardly been recognized by most physicians, and its danger in
            analogous physiological situations is much farther from their consideration.
        </p>
        <p>
            One of the things that happen when there isn't enough sodium in the diet is that more aldosterone is
            synthesized. Aldosterone causes less sodium to be lost in the urine and sweat, but it achieves that at the
            expense of the increased loss of potassium, magnesium, and probably calcium. The loss of potassium leads to
            vasoconstriction, which contributes to heart and kidney failure and high blood pressure. The loss of
            magnesium contributes to vasoconstriction, inflammation, and bone loss. Magnesium deficiency is extremely
            common, but a little extra salt in the diet makes it easier to retain the magnesium in our foods.
        </p>
        <p>
            Darkness and hypothyroidism both reduce the activity of cytochrome oxidase, making cells more susceptible to
            stress. A promoter of excitotoxicity, ouabain, or a lack of salt, can function as the equivalent of
            darkness, in resetting the biological rhythms (Zatz, 1989, 1991).
        </p>

        <p>
            Bone loss occurs almost entirely during the night, and the nocturnal rise in cortisol and prolactin has
            strongly catabolic effects, but many other pro-inflammatory substances also rise during the night, and are
            probably the basic cause of the increased catabolism. Increased salt in the diet appears to improve some
            aspects of calcium metabolism, such as reducing parathyroid hormone and increasing ionized calcium, when the
            diet is deficient in calcium (Tordoff, 1997).
        </p>
        <p>
            The kidneys can produce large amounts of carbon dioxide and ammonia, in the process of preventing the loss
            of electrolytes, while allowing acid to be lost in the urine. The ammonia is produced by the breakdown of
            protein. During stress or fasting, the loss of tissue protein can be minimized by supplementing the
            minerals, potassium, sodium, magnesium, and calcium. Salt restriction can cause aldosterone to increase, and
            excess aldosterone causes potassium loss, and increases the use of protein to form ammonia (Norby, et al.,
            1976; Snart and Taylor, 1978; Welbourne and Francoeur, 1977).
        </p>
        <p>
            Aldosterone secretion increases during the night, and its rise is greater in depressed and stressed people.
            It inhibits energy metabolism, increases insulin resistance, and increases the formation of proinflammatory
            substances in fat cells (Kraus, et al., 2005). During aging, salt restriction can produce an exaggerated
            nocturnal rise in aldosterone.
        </p>
        <p>
            During the night, there are many changes that suggest that the thyroid functions are being blocked, for
            example a surge in the thyroid stimulating hormone, with T4 and T3 being lowest between 11 PM and 3 AM
            (Lucke, et al., 1977), while temperature and energy production are at their lowest. This suggests that the
            problems of hypothyroidism will be most noticeable during the night.
        </p>
        <p>
            Rheumatoid arthritis and asthma are two inflammatory conditions that are notoriously worse during the night.
            Melatonin has been reported to be higher in patients with severe asthma and rheumatoid arthritis, and to
            promote the secretion of a variety of other pro-inflammatory substances. The peak of melatonin secretion is
            followed by the peak of aldosterone, and a little later by the peak of cortisol.
        </p>
        <p>
            The use of bright light (which suppresses melatonin) to treat depression probably helps to inhibit the
            production of aldosterone, which is strongly associated with depression.
        </p>

        <p>
            Both aldosterone and melatonin can contribute to the contraction of smooth muscle in blood vessels.
            Constriction of blood vessels in the kidneys helps to conserve water, which is adaptive if blood volume has
            been reduced because of a sodium deficiency. When blood vessels are inappropriately constricted, the blood
            pressure rises, while organs don't receive as much blood circulation as they need. This impaired circulation
            seems to be what causes the kidney damage associated with high blood pressure, which can eventually lead to
            heart failure and multiple organ failure.
        </p>
        <p>
            Progesterone, which helps to maintain blood volume (partly by preventing vascular leakiness, preventing
            excessive sodium loss and by supporting albumin synthesis) antagonizes aldosterone. Aldosterone antagonists
            are now being recognized as effective treatments for hypertension, water retention, congestive heart
            failure, arrhythmia, diabetes, kidney disease, and a great variety of inflammatory problems. (Synthetic
            drugs to antagonize aldosterone are most effective when they are most like natural progesterone.) Since
            aldosterone contributes to fibrosis of the heart and kidneys (nephrosclerosis), progesterone, the
            "antifibromatogenic steroid," should be helpful for those problems that have been considered irreversible.
            Aldosterone appears to contribute to the hyperglycemia of diabetes itself, and not just to its
            complications, by interfering with the interactions of insulin and cortisol (Yamashita, et al., 2004).
        </p>
        <p>
            One of progesterone's fundamental actions is to cause estrogen "receptors" to disintegrate; hypertonicity
            has this effect in some situations. Estrogen's effects are largely produced by increased tissue hydration.
        </p>

        <p>
            Aldosterone causes cells to take up sodium, while increasing their pH, i.e., raising their alkalinity
            (Mihailidou and Funder, 2005). Intracellular sodium has long been known to be a factor, along with swelling
            and alkalinity, in stimulating cell division (Cone and Tongier, 1971). A lack of salt stimulates the
            formation of serotonin, which in turn stimulates aldosterone synthesis--that is, a sodium restricted diet
            activates processes that cause cells to take up sodium inappropriately, in a situation reminiscent of the
            calcium deficient diet causing inappropriate calcification.
        </p>
        <p>
            Aldosterone, like stress or hypo-osmolarity, activates the enzyme (ODC) which produces the polyamines, that
            promote cell division, and that can probably account for some of the harmful effects of excessive
            aldosterone.
        </p>
        <p>
            Eating salty food around bedtime usually has a sleep-inducing effect, and it helps to maintain blood volume
            (which tends to decrease during the night), and to restrain the nocturnal rise of aldosterone, and other
            indicators of stress or inflammation. Eating gelatin, which lacks tryptophan, will reduce the formation of
            serotonin, and is likely to limit the formation of aldosterone.
        </p>
        <p>
            Pregnenolone can sometimes very quickly allow swollen tissues to release their water. This function is
            probably closely related to its antifibromatogenic function, since swelling and leaking set the stage for
            fibrosis.
        </p>
        <p>
            Hyperosmotic sodium chloride solutions (e.g., 7.5%) are being used more often for treating trauma and shock,
            because the concentrated solution increases blood volume by removing water from the extravascular spaces,
            unlike the "isotonic" saline (0.9% sodium chloride), which usually adds to the edema by leaking out of the
            blood vessels.
        </p>

        <p>
            A 5% sodium chloride solution is effective for promoting healing of damaged corneas, and solutions of 5% to
            10% sodium chloride are effective for accelerating the healing of wounds and ulcers. Other hypertonic
            solutions, for example glucose or urea, have been used therapeutically, but sodium chloride seems to be the
            most effective in a variety of situations.
        </p>
        <p>
            Thyroid hormone, by maintaining oxidative metabolism with the production of carbon dioxide, is highly
            protective against excessive water retention and loss of sodium and magnesium.
        </p>
        <p>
            Sometimes doctors recommend that constipated people should drink extra water, "to soften the stool." The
            colon is where water is removed from the intestinal contents, and when it is inflamed, it removes too much
            water. Several decades ago, it was recognized (Orr, et al., 1931) that hypertonic saline, given
            intravenously, would stimulate intestinal peristalsis, and could be used to treat paralytic ileus and
            intestinal obstruction.
        </p>
        <p>
            When water is taken orally, it is absorbed high in the intestine, long before it reaches the colon, so the
            recommendation to drink water for constipation can produce a situation that's the opposite of intravenous
            hypertonic saline, by diluting the blood. Using a hypertonic salt solution as an enema can have the same
            beneficial effect on the intestine as the intravenous treatment.
        </p>
        <p>
            Constipation physiology is probably analogous to the physiology of congestive heart failure, in which
            muscles are weakened and fatigued by swelling.
        </p>

        <p>
            In recent decades, the prevalence of congestive heart failure has increased tremendously, so that it is now
            often called an epidemic. Hyponatremia (too little salt, or too much water) is a recognized "risk factor"
            for congestive heart failure. In the failing heart, the muscle cells are swollen, causing the heart wall to
            stiffen, weakening its ability to pump. Osmotically shrinking the cells can restore their function.
        </p>
        <p>
            The swollen heart, like any muscle, loses the ability to quickly and completely relax, and so it doesn't
            fill adequately between contractions. Elastic tissues, such as arteries and lungs, stiffen when they are
            over-hydrated, losing their normal functions. In small blood vessels, swelling narrows the channel,
            increasing resistance to the flow of blood.
        </p>
        <p>
            When people force themselves to drink a certain amount of water every day, even when they don't feel
            thirsty, they are activating complex adaptive processes unnecessarily. Thirst is the best guide to the
            amount of fluid needed.
        </p>
        <p>
            When extra water consumption is combined with a low salt diet--as physicians have so often recommended--a
            healthy person can adapt easily, but for a hypothyroid person it can have disastrous effects.

                and (2) that the measure "effective water clearance" (EWC</strong>) provides better information about

            rationale for calculating a "tonicity balance," which involves using water and sodium plus potassium intakes
            and their renal excretion to reveal the basis for changes in body tonicity." "The water load was excreted

            When I started studying William Blake in the 1950s, it seemed that only English majors knew who he was, but
            today, I think more people might recognize The Tyger as Blake"s than would be able to identify poems by
            Keats, Byron, Shelley, or Wordsworth. After 200 years, his writing seems contemporary, while other poets"
            works have become dated, and are valued mostly as cultural background. But I don"t think this means that his
            work is any easier to understand than it was when he wrote it. It means that other poets tied their writing
            to frameworks which have receded into the background, while Blake"s words were chosen in a way that allowed
            them to travel across the centuries without loss. Even though such universality is a goal of science as well
            as of art, most of what passed for science in the 18<sup>th</sup> century is today of only historical
            interest.
        </p>

        <p>
            Everywhere in our culture, authoritarian ignorance has disproportionate influence. Most of the published
            work in our culture treats the succession of authoritarian academic/scien- tific/political cults as if this
            were simply the way history and human nature work, and must work. But this mechanical historical process is
            only superficial, and below this surface, individuals and groups have always lived as though time behaved
            very differently for them. William Blake was a person who investigated this discrepancy between official
            cultural progression, and real human possibility, and his ideas might be able to do essentially what he
            suggested they could do<strong>:</strong> Provide a way to by-pass the officially established mechanistic
            view of reality, into a more fully human reality. Since Blake ridiculed established doctrines in medicine,
            chemistry, mathematics, and Newtonian physics, many people have dismissed him as a religious nut, but the
            way in which he criticized them indicates that he simply believed that they were bad science<strong
            >;</strong> he also criticized conventional art and morality, because he believed that they were destroying
            art and morality.
        </p>
        <p>
            A group that was active in the 1950s, called Synectics, developed several mental procedures that they found
            to be useful in teaching people to solve problems creatively. These included ways to improve thinking by
            analogy, to get people out of the ruts of conventional thinking. Personification, fantasy, biological
            imagery, "making the familiar strange," they found, seemed to tap into natural biological and mental
            processes to increase the ability to direct energy toward valid solutions to practical or artistic problems.
            They found that experts had to overcome their special knowledge before they could usefully solve problems in
            "their field," and they showed that much of the mystery could be removed from the creative process. Simply
            putting aside dogmatic mental frameworks was crucial.
        </p>
        <p>
            When you believe that you have adequate, expert knowledge, a passive, logical, deductive form of mental
            activity seems appropriate. Deduction always goes from a higher level of generality to a lower level of
            generality. Mental passivity therefore is likely to be associated with the belief that we have the decisive
            knowledge already stored in memory. If we believe that we <em>create</em> higher degrees of generality, as
            appropriate solutions to novel problems, then we are committed to an active mental life. Perception,
            combined with the discovery and invention of new patterns in the world, will be actively oriented toward the
            future, while the deductive, merely analytical, manner of thought will be tied to the past.
        </p>

        <p>
            Blake"s work, I think, is of continued and increased interest because he discovered something of great
            importance, namely, how to avoid dogmatisms of all sorts. Many students who are assigned to write about a
            poem of Blake"s are puzzled, and ask what it means. When they find out that they understand the words and
            the syntax, it turns out that the only problem was that they were taught that they had to "interpret"
            poetry. And that they don"t think he could have meant what he said. Most twentieth century students are too
            stodgy to accept Blake"s writing easily. In the 1950s, some people couldn"t understand Alan Ginsberg"s
            poetry, because they didn"t think anyone was allowed to say such things. That is the kind of problem
            students have with Blake.
        </p>
        <p>
            But it"s not just high school and college students who can"t believe that Blake meant what he said. I
            recently reviewed the comments on The Tyger that have been published in the forty years since I wrote my MA
            thesis on Blake, and it seems that these academic experts are having the same kind of problem. Dostoyevsky
            wrote about this problem in The Double"it is the problem of self-assertion, of seeing oneself reflected
            everywhere in the world. In Dostoyevsky"s story, Dream of an Odd Fellow, the theme is stated even more
            clearly"the world is very boring, and <strong><em>everything seems the same as everything else,</em></strong
            > until you can escape from a certain interpretive framework, to see what is really present to you. In
            Blake"s phrase, if the many become the same as the few when possessed<strong>,</strong> "more, more," is the
            cry of a mistaken soul<strong>;</strong> Blake said, over and over, that the many do not become the same as
            the few, that we are always moving into a new world as we learn more, except when we find ourselves in the
            mental manacles of interpretation.
        </p>

        <p>
            It"s easy to forget how pervasive philosophical interpretation is in everyday life and in the so-called
            sciences, and how much the sciences owe to long-standing theological commitments. Within the last
            generation, many influential people have said that facts don"t matter (and I suspect that their favorable
            reception has owed everything to that attitude.) In the early 1960s, there was a controversy going on
            between two schools of thought in linguistics and the philosophy of science, the Katz and Fodor controversy.
            I think Fodor was in the minority at that time, at least among the most prestigious professors in the United
            States. Fodor said that if we wanted to know about language, we should find out how the language is used, by
            watching a variety of people using it. His opponents said that, if they were competent to speak the
            language, they didn"t need to do anything except to think, to understand everything about the language.
            Fodor was an empiricist, his opponents were rationalists. In mathematics, most people are still
            rationalists. A large school of contemporary thought about computers, called "Artificial Intelligence," is
            operating within a rationalistic framework. Chomsky"s "generative grammar" was ultra-rationalistic, and was
            easy to set up in computers, though it was perfectly useless in itself. Some physicists hold a philosophy of
            science that is essentially rationalistic. In Plato"s time, <em>
                all knowledge</em> could supposedly be derived by introspection and the analysis of innate ideas, and
            education consisted in "drawing out" the knowledge that was innate. (Aristotle, who didn"t subscribe to
            Plato"s rationalism, has nevertheless been blamed for holding opinions that weren"t sufficiently supported
            by observation. This was probably because he occasionally relied on the opinions of others, rather than
            because of any serious defect in his philosophical-scientific method.)
        </p>
        <p>
            It"s important to remember that Rationalism, as used here, isn"t simply a "love of reason," which is what is
            often meant when people speak of "rationalism." In its historical use among philosophers, rather than being
            just a devotion to rationality, it is a specific doctrine which denies that experience is the source of
            knowledge. Historically, Rationalism has been closely allied with mysticism, as an affirmation that
            knowledge comes from a source beyond the ordinary world of experience and beyond the individual. At the
            present time, it serves authoritarian science rather than authoritarian theology, though the basic doctrine
            is the same.
        </p>
        <p>
            Several contemporary schools of literary theory, sociology, anthropology, even biology, trace their ideas
            back to Ferdinand de Saussure"s analysis of language, reading into it a highly rationalistic doctrine for
            which there is no actual basis. Saussure"s most important idea was that it is impossible to analyze language
            into its structural units without simultaneously seeing its use in relation to the world of meanings.
            Without its meanings, it just isn"t language. This is a profoundly anti-rationalist insight, since it shows
            that symbols take their existence from the experience of communication. But once the symbols exist, they
            function by the ways they establish distinctions, "this" being defined by the ways it has been used in
            distinction to "those," "that," etc. Every time a word is used, its meaning changes a little, since every
            use occurs in a new communicative situation. The contemporary rationalistic academic trends prefer to
            isolate only the principle of "meaning through opposition," since it supports the rationalistic illusion of
            operating strictly on the symbolic level. The "symbolic level" is only an abstraction, and doesn"t exist
            independently.
        </p>

        <p>
            A few decades ago, there was a movement called General Semantics that tried to make people more conscious of
            the way symbols relate to reality. Their ideas were based on a distinction between the "concrete" use of
            symbols, and the various levels of abstraction. These distinctions, however, made sense only within a
            certain theory of how language works, which I think was wrong<strong>: </strong>It asserted that, if time
            and space were divided into sufficiently small units, symbols and language could be precise and factual. It
            ignored the distinction between reality as experienced, and reality as represented in theory. If you keep
            subdividing a person, John Smith, into smaller moments, you find that there is nothing that represents the
            known person. The person that you are really referring to is actually a summation of many moments"the
            summation is the only "concreteness." The person you know is a synthesis, and it is that imaginative
            synthesis of facts to which the concrete symbol refers. Generality exists in our knowledge of the world, and
            the distinction between concrete and abstract is likely to create confusion, and reinforces a specific
            ideological system. Incidentally, the word "concrete" derives from the roots "grown" and "together," so it
            is very close in its core meaning to "synthesis." A well constructed generalization can be concrete, and a
            seemingly simple term, such as "electron," can be "abstract." (Blake said that a line, no matter how finely
            divided, was still a line; a line exists in our imaginative synthesis of the world, and it is only a denial
            of that synthesis that can divide its unity into "infinitesimals.")
        </p>
        <p>
            Mathematics has its value in representing certain relationships or patterns, but the rationalistic illusion
            that the meaning is independently contained and fulfilled by the "algorithm," has led many people into
            dogmatisms and serious errors. "Coefficients of reality" are often neglected. In practice, you are not very
            likely to be mistaken if you assume that mathematical descriptions of physical states are always erroneous.
        </p>
        <p>
            In the 17<sup>th</sup> and 18<sup>th</sup> centuries, progress in technology and industry was already making
            rationalism seem inadequate, but it still served the social purpose of allowing the ruling class to claim
            that the doctrines it wished to enforce had the support of timeless, innate and universal principles. There
            was supposed to be a Great Chain of Being, a hierarchy in which the king and the lords were just below the
            angels, and Reason was a mathematically clear description of the way things were, and should be. As the
            chain of being finally broke up at the end of the 18<sup>th</sup> century, the king brought in the Rev.
            Malthus to explain how war, poverty, and disease served the divine, or kingly, purpose, by controlling
            population growth, justifying misery and social antagonism in a new way.
        </p>

        <p>
            There were philosophers, such as John Locke and David Hume, who argued that much of our knowledge is gained
            through the senses, and there were satirists, such as Henry Fielding, who ridiculed the supposedly divinely
            sanctioned class system, but Blake took a much simpler, but more radical position, in saying that "Reason
            isn"t the same that it will be when we know more," and that reason is only the ratio of things that are
            presently known, and not the source of new knowledge. Blake kept the idea that experience is the source of
            knowledge, without reducing "experience" to the "senses." Blake didn"t deny the existence of some innate
            ideas<strong>;</strong> he didn"t think we were born as a "blank slate," but there is more to the mind than
            what we are born with. Imagination and invention and mental striving were able to generate new forms. This
            commitment to experience as the source of knowledge, rather than just analyzing a stock of "innate ideas,"
            made Blake"s world one that was oriented toward the future, toward invention and discovery, rather than to
            memory, established knowledge, and tradition. In its essence, it was antidogmatic.
        </p>
        <p>
            Rationalism is a system of symbols, in which each symbol is demonstrated to have its own proper place and
            status. To the extent that reason is held to be "innate," the system will be prescriptive and judgmental,
            rather than simply descriptive, explanatory, and illuminating. When an alternative system is proposed, it
            may be considered a "heresy," if the system from which it dissents is both rationalistic and authoritarian.
        </p>
        <p>
            Except for the dangers involved in committing a heresy, it is very easy to follow the implications of the
            system that one finds in one"s own mind, since self-assertion contains no principle of corrective
            contradiction. Essentially, <strong>rationalism consists of thinking something is true because you thought
                of it.
            </strong>
        </p>
        <p>
            I think of the philosophical Rationalists as being the bureaucrats of the mind, making everything tedious
            and boring and repetitive. Eliminating Rationalism, then actual individualized full mental life can begin.
        </p>

        <p>
            Even a heresy, if it is based on rationalism, is past-oriented, and dogmatic. Over the years, scholars have
            ascribed most of the important heresies, as well as mainstream religious ideas, to Blake. Whatever
            interpretive system the scholars favor, they are able to find it in Blake"s work. Calling Blake "a mystic"
            is especially useful when the goal is to claim that the critic is getting at the deepest levels of meaning
            in Blake, even though there is no clear meaning for the word in contemporary English, and Blake didn"t use
            the term in a way that suggested he would approve of having the word applied to himself.
        </p>
        <p>
            Blake"s notes written in the margins of books make it clear that he wasn"t simply adopting anyone"s
            doctrinaire opinions, and that he was able to find useful ideas in the thoughts of others even when he
            disagreed with them on important issues. Blake was not a rationalist, but he agreed with Bishop Berkeley"s
            understanding of the importance of distinguishing thought from language. He recognized that Descartes,
            Locke, Hume, Newton, had inadequate ideas about the nature of "matter," but he didn"t accept the simplistic
            doctrine of extreme rationalism that matter doesn"t exist.
        </p>
        <p>
            When people consider Leonardo de Vinci, they usually make the point that he had mastered every field of
            knowledge, and so the question of "sources" and "influences" doesn"t come up. In the 18<sup>th</sup>
            century, London was the cultural center of the world<strong>; </strong>
            European, Asian, and ancient cultures and ideas were discussed in books, magazines, and conversations. Being
            an engraver, a painter, a poet, and a political activist, Blake"s circle of acquaintances was as wide as
            anyone"s could be. England has had, probably since the 17<sup>th</sup> century or earlier, a counter-culture
            of opinionated dissenters. I suspect that the people who spent several years studying the classics for a
            university education were somewhat culturally deprived, relative to the people who participated in the rich
            unofficial culture, where new ideas in art, science, and philosophy were being discussed. London was also
            the center of a world-spanning empire, a tyrannical class-system, and an industrial-commercial revolution.
            The past and the possible futures could be seen from Blake"s vantage point.
        </p>

        <p>
            Among all the published opinions about things that influenced Blake, I have seen only a few discussions of
            his treatment of scientific ideas, mainly his rejections of Newton"s mathematical and physical assumptions,
            and very few comments on Blake"s position on the major philosophical controversies of his time. A biologist,
            Jacob Bronowsky, wrote a book about Blake, but Bronowsky"s own biological, historical, and linguistic ideas
            were relatively conventional. Even though Blake"s work is full of images from biology, the critics ignore
            the fact that Emanuel Swedenborg published very advanced biological research in the middle of the 18<sup
            >th</sup> century, and that Erasmus Darwin was known for presenting his ideas on biological evolution in
            poetry (especially Zoonomia). The title of Blake"s book, The Four Zoas, has apparently never led scholars to
            ask whether it had anything in common with Zoonomia. Even though Blake made many disparaging remarks about
            Swedenborg"s religious books, many people have claimed that Blake was influenced by Swedenborg"s religious
            doctrines, while ignoring the possible influence of the scientific work.

            Although the idea that "contradiction produces change" is associated with Hegel"s "Dialectic," it was an old
            and well known theme in philosophy. When Blake"s idea, that "without Contraries there is no progression," is
            seen in context, I think it is appropriate to think that to a great extent, Blake derived the idea from a
            consideration of the sexes. "Generation," so often discussed in relation to the biblical "fall of man,"
            always leads to the issue of the productive interaction of the sexual contraries. The issue of sexual love
            permeates Blake"s work. I suspect that Blake produced even more explicitly sexual work, but since most of
            his work wasn"t really published, when his wife died in 1831, the bulk of his manuscripts and paintings were
            subject to the whims of their unsophisticated owners. But on the basis of his existing work, it is
            reasonable to say that sexual and imaginative energy was the motor that Blake saw producing intellectual
            advancement. This male-female principle of change was more fully explored by Blake than by anyone
            previously, since he made it concrete and personal, rather than abstract. Working in history, human energy
            ran into the constrictive, limiting elements, the tyrannies of policy, philosophy, and commerce. For Blake,
            the interaction of energy with those limits became a philosophy of freedom and revolution.
        </p>
        <p>
            While Blake discussed the importance of perception in understanding the world, he was remarkable in the care
            he took to make it clear that he saw the world "all alive," in which grains of dust or sand, birds, worms,
            ants, flies, etc., perceived and experienced in ways that were not different from those of human life.
            Bishop Berkeley, who said that the material world outside the philosopher"s mind doesn"t exist, added as an
            afterthought that it exists in the mind of God. If consciousness is the only guarantee of existence, there
            was no problem in the existence of Blake"s world, in which everything was alive and conscious.
        </p>
        <p>
            Everyone finds it almost obligatory to describe The Lamb as a symbol for Jesus, but then they find the
            Tyger"s symbolic meaning more problematic, and"from Coleridge in the early 19<sup>th</sup> century down to
            the newest publications at the end of the 20<sup>th</sup> century"people are boggled by the "obscurity" of
            The Fly. But in that poem, Blake makes it clear that there is no obscure symbolism, when he says "then am I
            a happy fly, if I live or if I die," etc. The animal poems are expressions of Blake"s evolutionary,
            vitalistic, cosmology. The tyger, at least, would be too much for a creationist doctrine to handle. If worms
            and flies and ants are conscious and in the same situation as human beings, the bonds of sympathy and
            forgiveness are universal.

            In a world that"s alive and developing, new knowledge is always possible, and imagination has the prophetic
            function of reporting the trends and processes of development, illuminating the paths toward the future.
            Reason is subordinate to invention and discovery.
        </p>
        <p>
            The dualistic conception of matter as distinct from energy and consciousness is a constrictive illusion put
            in place by the forces of empire, and the living reality would be freed from the inert husks of the wrongly
            conceived natural world, when in the future the world was freed of tyranny. After Blake, it would be nearly
            another century before others would see that the crude materialism of Newton and the Natural Philosophers
            was essentially a life-denying culmination of the worst trends of official religious dogma.
        </p>
        <p>
            A complete survey of Blake"s references to Christianity would be voluminous, and not all of them are
            immediately clear<strong>, </strong>
            and require a careful placing in the context of the ideas that were being discussed in London at that time.
            But it"s hard to reconcile the common description of him as a mystic with his reference to "Old Nobodaddy
            aloft," or with his comment that Jehovah gives us a knock on the head, and Jesus soothes it. He always
            defines god in human terms, so from the conventional viewpoint, he would probably be considered as an
            atheist or pantheist, but he didn"t describe himself or his friends as atheists. When people called Tom
            Paine an atheist, Blake defended him against the charge. Other friends, Mary Wollstonecraft and William
            Godwin, were sometimes called atheists, but in their writings, they never expressed very unconventional
            religious ideas. When we recall that in the early 1990s, George Bush expressed the idea that atheism should
            be illegal, it is easy to imagine that people in 18<sup>th</sup> century England wouldn"t have felt that it
            was safe to be called atheists.
        </p>
        <p>
            In 1803, Blake apparently said something like "damn the king," while getting a drunk soldier out of his
            yard, and was tried for sedition or treason. He was acquitted, because his far more scurrilous written
            comments hadn"t been published, and it didn"t occur to the government to look for documentary evidence to
            support their case. The fact that he printed his own work, and sold only a few copies of his books to
            affluent friends, probably saved his life, but it accounts for his obscurity during his own lifetime.
        </p>

        <p>
            Tom Paine"s writing was published and widely read in prerevolutionary America, but he was considered a
            criminal in England, and Blake was credited with saving his life by helping him escape to France.
            Politically and ethically, Blake"s writing is similar to that of Paine, Godwin, and Wollstonecraft (often
            called the "first feminist"), but his language is usually more vivid. It was probably the clarity of his
            political opposition that made his work unpublishable during his lifetime. The first "complete" collection
            of his work was published in 1927, and until that year, very few people had seen more than a few of his most
            famous poems.
        </p>
        <p>
            Blake printed his work by hand, without a press, by writing the text backwards on copper plates, surrounded
            by his drawings, and then etching away the surrounding copper, so that the image remained elevated, and
            could be inked and printed as if it were a wood-block. If he hadn"t devised this method for printing a few
            copies of his books, it isn"t likely that much of the work would have survived.
        </p>
        <p>
            Shortly after the French Revolution, William Wordsworth was associated with the Blake-Wollstonecraft-Godwin
            group"s defense of the revolution, but he moved away from the ideals of that group, and adopted more
            socially acceptable ideas. He finally became England"s poet laureate. Liberty, equality, and brotherhood
            were replaced by blandly conformist ideas.
        </p>

        <p>
            The type of individualism that Wordsworth came to advocate was interesting because it was a rejection of
            exactly that part of Blake"s belief that Blake considered to be the essence of Christianity, namely,
            forgiveness, brotherhood, and bonds of sympathy connecting all beings. In its place, Wordsworth adopted a
            memory-centered doctrine. During Wordsworth"s lifetime, his ideology was exceedingly successful, but its
            rationalistic overtones have kept it tied to the past<strong>;</strong> it had nothing to offer the future.
            I think we can get some insight into Wordsworth"s mind by considering that, on the basis of reading Blake"s
            <em>Songs of Innocence and Experience,</em> he decided that they were written by an insane person. (Blake
            was aware that slow-witted people, who couldn"t follow unconventional thoughts, often considered him to be
            crazy.}
        </p>

        <p>
            Everywhere in Blake"s work, it is clear that he never underestimated the possibilities of the future, and
            never imposed false limits onto anything, but he didn"t tolerate vagueness or empty abstraction. Sharp
            definition was essential, and unique particulars were the basis for beauty and knowledge.
        </p>
        <p>
            For Blake, the dialectical principal was a feature of the world itself, but it also informed his method, his
            technique, and his "rhetoric." One of Blake"s powerful insights was that intellectual clarity is achieved by
            contradiction, opposition, contrast, making distinctions as well as comparisons. The principle of
            intensification through opposition had special features when it was developed in his painting and writing.
            Blake gave much of the credit for his style of thinking to the process of spending thousands of hours in the
            practice of etching. The image you create in the conventional etching technique is made when acid "bites"
            into the lines that will be inked<strong>;</strong>
            in Blake"s new technique, the image is made permanent by the acid"s corroding away of everything except the
            sharply defined image. The decisive, dividing, line is essential. Anyone who has spent even a few hours of
            intense effort working in dry-point or etching understands that, when you stop, the appearance of the world
            is altered by changes that have taken place in your eyes and brain. Often, his "metaphors" are literal
            imaginative insights that have great generality. This kind of knowledge distinguishes the work of a
            craftsman from that of an academic. The probability is that Blake"s art led him to appreciate compatible
            ideas when he found them, and it doesn"t seem likely that he was "influenced" by them the way an academic is
            influenced by books, since Blake had his own "sources" that are generally neglected by intellectuals.
        </p>
        <p>
            Blake found that contrasts made meanings clear, and made language vivid. Heaven and Hell, Clod and Pebble,
            Lamb and Tyger, Angel and Devil, Greek and Jew, Innocence and Experience, presented contrasts that
            encouraged the reader to think about the range of possibilities Blake had in mind. He was always consciously
            trying to energize the reader"s mind to get out of dogmatic ruts, to look at things freshly, so he often
            used the polarities in ways that would surprise the reader, ironically reversing familiar references. A
            pious commonplace would be contrasted with the disturbing realities that it normally hid. Both in his
            writing and in conversation, Blake was often playful and teasing, and over-serious people have usually taken
            him too literally.
        </p>
        <p>
            Academic commentators are so often attached to their erudite pieties that it seems that they can"t read
            English. In the 18<sup>th</sup> century, a clod meant just what it means in the 20<sup>th</sup> century,
            either a lump of dirt, or a lunkhead. In the Clod and the Pebble, when the Clod speaks the properly
            sanctimonious phrases, justifying its oppressed misery with a dogma, we have a clue regarding Blake"s
            attitude, but then he makes it perfectly clear by speaking of Heaven"s despite, literally, Heaven"s malice
            (a concept that appears many times in different forms in other parts of his work). Either the commentators
            assume that the word "despite" had a different meaning in the 18<sup>th</sup>

            century (it didn"t), or they assume that Blake made an error of diction, because they choose to alter the
            meaning to "despite Heaven." Just as judges aren"t allowed to change the wording of the laws that they
            interpret, literary experts aren"t allowed to rewrite texts to make them better suit their interpretation.
        </p>
        <p>
            The same insensitivity to the world of concrete experience that has allowed so many commentators to read
            their own ideas into Blake, ignoring what he said in plain English, makes satire and irony and sarcasm
            inaccessible to many people who otherwise seem intelligent<strong>;</strong> this is especially apparent
            when scientists comment on literature. Forming an imaginative synthesis of the writer and his meaning
            requires mental flexibility and energy, rather than just analytical acuity.
        </p>
        <p>
            Everyone who described Blake"s physical appearance remarked on his large head. Blake commented that he
            didn"t like to travel or undergo physical strain, because of its effects on his health. The brain is an
            energetically expensive organ, which consumes large amounts of glucose. A very large brain puts a special
            burden on the liver"s ability to store energy, and is likely to make a person conscious of physiological
            processes. Blake"s descriptions of the process of seeing show that he was integrating his experience into
            his knowledge, describing brain physiology, incorporating his perceptions and the best scientific knowledge
            that was available to him, into a philosophical description of the place of conscious life in the world. The
            pulsation of an artery was the unit of time, a red blood corpuscle was the unit of space, enclosing eternity
            and infinity, eliminating arbitrary and abstract entities, and placing human life within cosmic life, while
            revealing cosmic life within the individual.
        </p>
        <p>
            The idea of a "biological cosmos" seems strange only when it is considered against an ideology which
            maintains that life is alone in an immense dead universe. The assumption of a dead, unintelligent, randomly
            moving physical world is the creation of a series of theological ideas, which Blake perceived as essentially
            Satanic. Blake used the language of these theologies, but inverted them, showing the ways they were used to
            obscure reality, and to impose a perverse way of life onto the living world.
        </p>
        <p>
            Fred Hoyle, the astronomer, said "If this were an entirely scientific matter, there is little doubt from the
            evidence that the case for a fundamentally biological universe would be regarded as substantially proven."
            (1989)
        </p>
        <p>
            Over the last few decades, biologists feel that they have established the "biochemical unity of life," in
            which biochemical cycles and genetic codes are widely shared. The idea of ecological interdependence has
            come to be recognized as an essential part of life, or (as demonstrated by Vernadsky, and suggested by
            Hoyle) a cosmic principle. Blake often called himself a Christian, and defined Christianity in many novel
            ways, as art, love, politics, science, but specifically, in his version of Christianity, forgiveness was an
            essential idea, and nothing lives for itself only. Blake"s Christianity as Art was a concrete part of
            living, and he ridiculed some of the abstract theosophical definitions of god that were common in his time.
            When his remarks are considered against the background of Spinozistic pantheism, it is the intensification
            and personalization, the avoidance of abstractions that could permit the attribution of passivity or
            inertness to any part of reality, that stand out. When he said that the world is alive, he meant that it is
            a defect of perception that makes Newton"s world seem passive, empty, and dead. A few years ago, a movement
            that called itself "deep ecology" tried to absolutize the ideas of ecology<strong>;</strong>
            Blake"s view of the interactive unity of life was as well thought out as any that preceded Vernadsky"s
            cosmology.
        </p>
        <p>
            Rather than elevating any of the ideas of Christianity to an absolute doctrine, Blake used them as parts of
            an organic whole. The principle of forgiveness was presented as the appropriate response to a world which is
            always new. The desire for vengeance comes from a delusive commitment to the world of memory. Virginity is
            constantly renewed in the world of imaginative life. While Blake said that you can"t forgive someone until
            they stop hurting you, the desire to be forgiven indicates that there is an opportunity to resolve the
            problem.

            Although most mathematicians and computer-so-called-scientists are committed to a rationalistic,
            past-oriented view of their mental operations, and some scientists accept that ideology along with
            mathematics, the valid, discovery-oriented sciences have to be future-oriented. A first step in avoiding
            dogmatic assumptions might be phrased as "remembering what you are," a living being, and asking how you know
            things<strong>: </strong>
            The interaction with other beings, exchanging energy and information with the environment, experiencing
            yourself in the world.
        </p>
        <p>
            Holistic medicine and holistic psychology came into existence as attempts to overcome the dogmatic
            compartmentalization of reality that is endemic. Whenever rigidity is a problem, looking for ways to create
            new patterns that by-pass the petrified pattern can lead to a solution. Parkinson"s disease and other
            physical problems have been approached using techniques of intensified or varied stimulation. Increased
            stimulation--even electromagnetic stimulation-- appears to open alternative patterns. Music, dance, and
            swimming have been used successfully to improve fluidity in various neurological diseases. Kurt Goldstein
            (<em>The Organism</em>) worked with brain injuries, and found that the brain has a variety of ways to
            restore a new balance. Raising the amount of energy that"s available can allow natural processes to create a
            better synthesis. Political and social problems that are culturally determined may follow rules similar to
            those of organic brain disease.
        </p>

        <p>
            Optimal assumptions, when assumptions are necessary, are those that don"t commit you to undesirable
            conclusions. For example, in the 1950s, some people made the assumption that nuclear war was inevitable, and
            made large investments in "fallout shelters," which were conceived in terms of world war II bomb shelters,
            and so resources were diverted from other investments, such as education, which didn"t in themselves
            foreclose future possibilities. Self-fulfilling prophecies and self-limiting assumptions are often built
            into supposedly practical activities.
        </p>
        <p>
            The assumption that cancer is genetically determined, and the assumption that regeneration is impossible in
            the heart or brain, are self-limiting assumptions that have been immensely destructive in biology and
            medicine. There was no reason to make those assumptions, except for the rationalist culture. Physics,
            biology, and cosmology are manacled by many unnecessary assumptions. The limits of adaptation, the extent of
            life"s potential, can"t be discovered unless you look for them, but the sciences have built many artificial
            limitations into their systems.
        </p>
        <p>
            Avoiding unnecessarily limiting assumptions, looking for patterns rather than randomness, looking for larger
            patterns rather than minimal forms, avoiding reliance on verbal and symbolic formulations, expecting the
            future to be different"these are abstract ways of formulating the idea that the world should be seen with
            sympathetic involvement, rather than with analytical coldness.
        </p>
        <p>
            Almost everything which has been denounced as "teleological" has turned out to be much closer to the truth
            than the mechanistic views that were promoted as "more scientific," and many horrors have been committed by
            people who have said that nature shouldn"t be "anthropomorphized," that subjective feelings shouldn"t be
            attributed to "the experimental material." The surgeons who operate on babies without anesthesia are
            operating on the assumption that any being which can"t say "I"m going to sue you" is unable to experience
            pain.
        </p>
        <p>
            When we analyze the ideas of chemical reaction equilibrium (burning something, for example), or biological
            adaptation or growth or learning, and see that they are strictly directional in time (which is the basic
            meaning of "teleological"), and consistent with Aristotle"s description of causality, we can see the
            mysticism that has been imposed on our culture with the idea that "teleological explanations are
            unscientific."
        </p>
        <p>
            Blake was clearly aware that the reason for making limiting assumptions was to maintain control, and to
            profit from another"s suffering. Seeing that the sadistic assumptions that were put in place to regulate
            human life rested on a dichotomizing of soul from body, Blake"s correction was to replace them with a unity
            of consciousness and substance, a living world rather than a dead world.
        </p>

        <p>
            An imaginative study of his work has the potential to rouse one"s abilities and to open an unlimited world
            of possibilities. "I give you the end of a golden string, Only wind it into a ball, It will lead you in at
            Heaven"s gate, Built in Jerusalem"s wall." Blake knew that his work, like anything new in the world, could
            be understood only by an active mental process.
        </p>
        <p>
            Every communicative act is original, and understanding it is an invention, a projection, <strong><em>an
                    imaginative synthesis.</em></strong> We can sometimes finish another person"s sentence, the way we
            anticipate the notes in a melody<strong>;</strong> we predict the intended meaning. If the symbols carried
            the meaning in a passive rationalistic way, the person receiving the symbols would receive nothing new. <em
            >Intellect is a process of imaginative synthesis, or it is nothing.</em>
        </p>
        <p>
            Blake devised "a system" that would make it possible to think about the world without unconsciously making a
            commitment to the false limits. He showed, by working within this new philosophical synthesis, that Art,
            Science, and Politics are structurally and substantially interdependent. The question I asked in the title,
            "can art instruct science?" isn"t the right question once you see the world from Blake"s perspective, since
            Science is Art, and both must be based on experience and imagination.
        </p>
        <p>
            Blake used, in a new way, the things that were available in his culture, to reveal the process of creation,
            on all its levels. He consciously used language in a new way, to free the reader from the stereotypes of
            conventional language. His methods are relevant, as he knew they would be, for other times and situations.

                NOTES AND QUOTATIONS</strong>
        </p>
        <p>
            I happened to read Swedenborg's scientific work just as I was getting interested in concentrating on
            becoming a biologist, and I realized that it was his scientific knowledge that shows up in Blake's imagery,
            far more than his theology, which Blake obviously despised. By chance, just after I finished my master's
            thesis on Blake, I got a job at a Swedenborgian college (Urbana University), where I saw in traditional form
            the small minded theologism that Blake had seen in Swedenborg. As a result of those experiences, I greatly
            appreciated the book, <em>
                The Heaven and Hell of William Blake,</em> by Gholam-Reza Sabri-Tabrizi, which apparently hasn't been
            very well received academically.

            Blake"s imagery indicates that he had a great interest in the physical and biological sciences, and he
            apparently had some direct contacts with the leading scientists in London, some of whom are lampooned in <em
            >Island in the Moon.
            </em>Some of Swedenborg"s discoveries were probably discussed in these groups.
        </p>

        <p>
            Although Swedenborg"s original works in anatomy and physiology were probably his most impressive
            contributions, he was also a pioneer in paleontology, cosmology (the nebular hypothesis, in particular),
            magnetism, crystallography, metallurgy, and endocrinology.

            E. P. Thompson"s <em>Witness against the Beast</em> is an extremely valuable source for clarifying Blake"s
            vocabulary.

            In the "scientific" philosophies of Blake"s time, it was common to speak of matter and its primary and
            secondary qualities. Blake understood that this view of matter was a derivative of awful theologies<strong

            Since the difference between a Rationalistic view of the world and a creative view is largely a question of
            the reality of time, it"s worth mentioning the work of an astronomer whose cosmological view was based on
            the reality of time:"Possibility of experimental study of properties of time," N. A. Kozyrev, Russian,
            September 1967, USIA document in English, 49 pages, 1971. J. Narlikar more recently did similar work,
            including his collaboration with H. Arp, described in Arp"s<em>
                Seeing Red: Redshifts, Cosmology, and Academic Science,</em> Apeiron, Montreal, 1998.
