From the international Amalgam Mailing list : Mercury Amalgam: Contamination of Human Nto moderate nerve and brain disease, with the person exhibiting psycho-behavioral symptoms including depression, irritablity, memory loss, signs of disturbed kidney function, minor tremors and other neurological problems. Sub-clinical illness is transformed into overt clinical illness at a level of about 750 mcg/g. The smallest amount of mercury that will not cause damage is unknown. [Denton, Sandra, “The Mercury Coverup.” Health Consciousness Magazine, June 1989.] In fact, the release of mercury from dental amalgams makes the predominent contribution to human exposure to inorganic mercury, including mercury vapor, in the general population. [University of Rochester School of Medicine (Thomas Clarkson, D.D.S., John Hursh,M.D.) and the Karolinska Institute in Stockholm, Sweden (Magnus Nylander, D.D.S. and Lars Friberg, M.D.), the world’s foremost researchers on mercury toxicity.] Amalgam fillings lose 72% of the mercury content in 5 years. Based on the known toxic potentials of mercury and its documented release from dental amalgams, usage of mercury-containing amalgam increases the health risk of patients, dentists and assisting dental personnel. [International Conference of Biocompatibility of Materials, Colorado Springs, Nov 1988. Tacoma, Washington: Life Sciences Press, Nov 1988.] The overt effect on dental personnel is in evidence by the general lack of calmness, irritability and tension observed in the general dentistry population. Correlation Between Mercury and Multiple Sclerosis There is some degree of evidence that the presence of mercury in the brain is a co-factor in the development of multiple sclerosis. Interestingly, patients having multiple sclerosis are found to have mercury levels eight times higher than neurologically healthy controls. It is a matter of scientific fact that inorganic mercury is capable of producing symptoms that are indistinguishable from those of multiple sclerosis.[Ahlrot et al., Nutrition Research, 1985 supplement. Second Nordic Symposium on Trace Elements in Human Health and Disease, Odense, Denmark, Aug 1987.] Categories of Mercury-induced Pathology Physicians, dentists and toxicologists who have treated the increasing number of people with problems associated with mercury have identified six general categories of pathology: (1) Allergies. Mercury combines with allergens to more readily rupture white blood cells than with allergens alone, (2) Immunological diseases, (3) Collagen diseases (further accentuated when dental fluorides are administered, (4) Cardiovascular diseases, (5) Neurological degeneration and (6) Psychological and behavioral disorders caused by systemic physiological or neurological damage. It is also interesting that each of the first five areas uses the element manganese - the action of which is blocked by mercury. Physiological Toxicology of Mercury in the Human Body Mercury atoms have a distinct tendency to combine with organelles within the neuron, eventually killing it. Because of this tendency, mercury rates as a primary co-factor in dementia, especially as expressed in Alzheimer’s syndrome. How do the mercury ions end up in the brain in the first place? Because amalgam fillings contain mercury, silver, zinc, tin, copper and nickel, electrolytic action is induced in the mouth, which frequently maintains an acid pH. Electrical charges induced free metallic ions which escape both in liquid (saliva + mercury atoms) and vapor form. Bacteria, both in the mouth and the intestinal tract, interact with elemental mercury to form methyl mercury compounds, which are more than 100 times more toxic than the original mercury in the fillings. Mercury vapor which makes its way into the nasal sinuses makes its way to the brain via axonal transport when mercury ions become part of the electrical transport mechanism between neurons. Vapor inhaled into the lungs enters the bloodstream via the capillaries and spreads systemically throughout the body. Curiously, when a pregnant human female also has mercury amalgam fillings, the fetus tends to absorb systemic mercury in a process ironically designed to protect the mother. Unfortunately in this situation, the human baby emerges with a red blood cell count 30% higher than the mother, and as mercury readily combines with hemoglobin the baby is more highly contaminated with mercury. This presents an additional cofactor for learning disabilities and minimum brain damage, to which vaccines (especially DPT) contribute once the baby is born. Hemoglobin and hemocrit elevation from mercury exposure, combined with depleted oxygen transport because of the tendency of mercury to displace oxygen by taking its place in hemoglobin, results in fatigue - chronic fatigue. It is certain that mercury is a co-factor in chronic fatigue/immune depression syndrome, as reversal of fatigue related symptoms and immune depression is known to have been mediated within two weeks of amalgam removal. Animal Tests of Systemic Mercury Absorption In 1989 and 1990, tests were conducted with pregnant sheep in which radioactive mercury amalgams were inserted. Each sheep had 12 molars filled. Radioactivity was detected within two days in the jaw bone, lungs, and intestines. Within 140 days, mercury was detected in the liver, kidneys, spleen, thyroid and pituitary glands, as well as in other tissues. Mercury was also detected in lambs born to pregnant mothers in the tests, and the milk of the mothers contained mercury at levels eight times higher than in the blood. The sheep were fed twice a day, allowing the chewing action to release mercury. The amalgams implanted in the sheep were smaller than those typically implanted into humans, indicating that human-size implants cause an even greater problem. This study on sheep was featured in an episode of 60 Minutes on CBS. Dentists in charge of the American Dental Association (ADA) predictably reacted to publication of the study and the presentation on 60 Minutes, as detailed earlier in this chapter. Doctors at the ADA complained that “sheep chew more than humans” and that unlike humans, the sheep had all 12 fillings installed at once. However, at the 1992 Seattle Conference of Clinical Toxicologists, a Dr. Lorscheider reported finding similar data on mercury toxicity in monkeys, which chew the same as humans, and found evidence that standard methods used by dentists to measure mercury exposure (blood, urine) do not look for the presence of mercury where it resides the most - in tissues and organs. Other speakers at the Seattle Conference supported these findings. Further Data on the 1991 University of Kentucky Study correlating Mercury Deposition as an Alzheimer Co-factor Scientists at the University of Kentucky examined autopsied brains of ten Alzheimer’s patients, compared with ten age-matched non-diseased controls, and found increased ratios between mercury and selenium, as well as increased ratios of mercury and zinc. Selenium and zinc are utilized by the human brain in a process that serves to protect the neurons from mercury.The brains of Alzheimer patients had higher levels of mercury, especially in the cerebral cortex and areas relating to memory retention. Studies conducted in 1990 and 1991, however, showed results that were even more interesting relative to trace element imbalances in Alzheimer patients. The 1991 Study on Trace Element Deficiencies in the Alzheimer Syndrome Brain In a study similar to the University of Kentucky that analyzed autopsied brains of Alzheimer patients and age-matched disease-free controls,[Bjorkland, G. “Mercury as a potential source for the etiology of Alzheimer’s disease.” (1991).] trace element concentrations were analyzed using a technique called instrumental neutron activation analysis. The elevation of mercury in the Alzheimer patient was the most noticable difference, especially in an area of the brain called the nucleus basalis of Meynert (nbM), a primary area involved with retention of memory. This research yielded other interesting results which may indicate additional mechanisms relating to mercury-caused neurological alteration in the brain. It was noticed that (1) the interaction of mercury with the essential trace elements selenium and zinc, which diminish in the presence of mercury, result in a deficiency of these two essential elements and lead to cellular dysfunction, (2) cell membranes of neurons become bound up with mercury, interfering with enzyme activity and causing increased membrane permeability and leading to an altered ability to regulate the flow of elemental or molecular ions, morphological changes or cell death,[Could this be a covert reason why both mercury and aluminum salts are used as adjuvants in vaccines?] (3) mercury binds to tubulin, a protein subunit of microtubules in the brain[Tubulin is a protein substance that is essential for the formation of neurofibril matrix essential trace elements selenium and zinc, which diminish in the presence of mercury, result in a deficiency of these two essential elements and lead to cellular dysfunction, (2) cell membranes of neurons become bound up with mercury, interfering with enzyme activity and causing increased membrane permeability and leading to an altered ability to regulate the flow of elemental or molecular ions, morphological changes or cell death,[Could this be a covert reason why both mercury and aluminum salts are used as adjuvants in vaccines?] (3) mercury binds to tubulin, a protein subunit of microtubules in the brain[Tubulin is a protein substan All in all, mercury in dental amalgams destroys the existing brain, the existing memory and prevents new brain cells from being made. The fact that this research is known and the process is allowed to continue indicates that it is being done intentionally. By the year 2020 we will have 60 million people in the United States over the age of 65, 12 million of whom will probably have Alzheimers syndrome from deposition of mercury and aluminum, according to the latest projections. The 1990 Brain Research Study on Alzheimer’s and Heavy Metals A study carried out in 1990 by three psychiatrists[ Wenstrup et al, “Trace element imbalances in isolated subcellular fractions of Alzheimer’s disease brains”, Brain Research¸ Vol 553, p125-131, 1990.] was conducted to determine the trace elements composition and imbalances in the brains of patients with Alzheimer’s. The brains from ten autopsied Alzheimer’s patients and 12 control patients of the same age without Alzheimer’s were evaluated. The most significant imbalance of metals found in the Alzheimer patients was an elevated mercury level and an elevated level of bromine. Levels of mercury were especially significant in the cerebral cortex, especially in an area called the nucleus basalis of Meynert, a primary center of memory retention. Short term memory loss is initially the most common complaint. Researchers have also found significant levels of mercury in the hippocampus and amygdala, which are also structures that relate to memory.[Note: Recall that the hippocampus is also severly damaged by fluorides. It seems like we have a large interrelationship here, don't we? The end result is the DOCILING of the population] Mechanisms of Neural Alteration from Mercury Intensive scientific research on this subject has revealed the nature of neural alteration that occurs because of the long-term presence of heavy metals, especially mercury, in the human brain. (1) The elevation of mercury in the brain interferes and inhibits protein synthesis, and causes a general reduction in the neural levels of DNA and RNA, which are the carriers of genetic information, (2) Since mercury binds to a substance called tubulin, a protein subunit of microtubules that run between brain cells, the microtubules become clogged[In fact, when mecury binds with tubulin, it results in neurofibrillary tangles between neurons instead of clear microtubules. Neurofbrillary tangles are always seen in the brain of Alzheimer’s patients. Extensive studies have also been conducted on rats to check this evidence.] , (3) Mercury binds with the cell membranes of the neurons themselves, interfering with sodium and potassium enzyme function, causing excess membrane permeability, especially in terms of the blood-brain barrier[Less than 1ppm mercury absorbed into the bloodstream can impair the blood-brain barrier. Ref: Koller,L.D. “Immunotoxicology of heavy metals” International Journal of Immunopharmacology, Vol 2, p.269, 1980; Koller L.D., “Immunosuppression produced by lead, cadmium and mercury” American Journal Vet. Res., Vol 34, p1457, 1973.] , which promotes entry of materials into the brain that would not ordinarily be a problem. It is for this reason that vaccines contain adjuvant compounds containing mercury (and aluminum). It is one of the revelations that supports the concept that the medical industrial complex has known about this all along and has been intentionally pumping heavy metals into the population. (4) Mercury interacts with trace elements zinc and selenium, causing shortages of these important trace elements which subsequently diminish neural and immune system capabilities. There is no doubt in the minds of scientists that mercury, acquired mostly from seafood (from industrial pollution) and mercury amalgam dental implants, plays a definitive role in neurological deteriorization in Alzheimers syndrome. Interesting Parallels with the Early German discovery of Mercury Effects and the Inculcation of the Prussian Educational System in the United States It is interesting that much of the early (1920’s) definitive research that determined the effect of mercury on the brain was done in Germany, indicating that mercury implantation might have later been included as part of the generalized plan to inhibit neurological activity in the population. It is also interesting to note that the Prussian system of education inculcated into the United States was designed to reduce the thought capacity of the general population, while preserving an elite one percent at the top. Coincidence? I don’t think so. It is also interesting, in light of this, that Germany has banned the use of mercury amalgam implants, but the German-based scientific technocracy in the United States encourages it. They can ban mercury in paint (1991) but they can’t ban it from the mouth. Federal Drug Administration Collusion in the Mercury Coverup One of the interesting statements by the American Dental Association is that “the Food and Drug Administration in 1987 classified mercury amalgam as a Class I dental device.” The FDA rules state that all “dental devices” must be certified as safe and effective. Class I is the safest. Class II requires general performance standards. Class III requires special controls to insure a reasonable degree of safety. The fact of the matter is that the ADA statement is not accurate. Research indicates that the FDA does not certify mercury amalgam as safe - only the alloy that the dentists mixes with it. Amazingly, the FDA certifies liquid mercury itself as a Class I “device”. The U.S. Department of Health and Human Services states that “the available research evidence is not specific enough or strong enough to make sound pronouncements about the human health risks from dental amalgam. The potential for effects at levels of exposure produced by dental amalgam restorations has not been adequately studied.” According to FDA mandates, a device where insufficient information exists must be classified under Class III. The fact that mercury liquid is classified as Class I and amalgam itself actually remains unclassified, means that the manufacturer is not required to furnish proof of safety. Without scientific proof provided by the manufacturer, complaints about mercury amalgam end up nowhere. In 1991, the FDA Dental Products Panel agreed with the HHS determination that “sufficient scientific data does not exist to allow a conclusion” as to whether mercury amalgam is a health risk to patients.” A Health and Human Services report in 1993 refers to the existance of hundreds of complaints about adverse reaction to mercury amalgam as “anecdotal” and “bogus.” Conspiratorial criminal negligence? Yes. The only thing to be gained is the gradual mental degeneration of the population. But, why would they want to do that? The Swedish Conclusion Several determinations made by Sweden in 1986 and the 1990’s have already been mentioned, but one determination not yet mentioned occurred in 1987. Sweden’s National Department of Health engaged an expert committee in 1987 to review the safety aspects of mercury amalgam. According to the committee, “from the toxicological point of view, mercury is too toxic for use as a filling material, and dentists should use other materials as soon as they are available.” It is this determination which contributed heavily to the Swedish ban on the use of mercury in dental restorations. Some Effects of Mercury on Human Physiology 1. Research indicates that mercury will penetrate the blood-brain barrier around the brain - the thin membrane which acts to separate the blood from the functional elements of the central nervous system. The blood-brain barrier, as well as being a physical barrier to undesirable metabolic materials outside the brain, also has other regulatory functions which control passage of select biological substances from the blood to the nervous system. Impairment of the blood-brain barrier can occur with absorption of less than 1 part per million ( 2. Studies of biochemical changes in the nervous system resulting from mercury seem to indicate a selective inhibition of protein and a great reduction of amino acids being incorporated into brain tissue. 3. All mercury compounds cause the same type of structural damage to the brain, but to different extents. 4. Methyl mercury released from amalgam produces complex changes in the metabolic response of the brain, suggesting impairment of metabolic control. The alterations in brain metabolism occur at doses far below those producing toxicity in rats. 5. Human autopsy studies have revealed brain damage in persons exposed to both organic and inorganic mercury compounds. 6. Neurological disturbances from mercury amalgam consist mainly of mild tremor, failure of muscle coordination and irregular movement, sensory and visual loss of acuity. 7. The central nervous system appears to be the first to exhibit functional disturbance. The toxic effects are produced after the body converts the elemental mercury vapor into murcuric ions. 8.Progressive constriction of the visual fields, often progressing to blindness, has been reported repeatedly in almost all significant exposures of humans to mercury. 9. Even at low concentrations, methyl mercury inhibits the synaptic uptake of the neurotransmitters dopamine, noradrenaline and serotonin. These substances are effectively prevented from getting into the CNS and performing their functions. It is interesting to note that Parkinsons disease results from an impairment of dopamine in the brain. A study in 1981 reviewed six cases of mercury exposure and subsequent development of Parkinsons disease. 10. The effect on the kidneys from mercury is well documented in scientific literature. Mercury, therefore, is “nephrotoxic” (toxic to the kidneys). Pathological biochemical damage was found in the kidneys of various animals who had been exposed to mercury in concentrations below those levels presently considered as “safe” by WHO. Another significant fact is the animals appeared to be outwardly healthy. 11. Chronic exposure to mercury may cause an excess of serum proteins in the urine which may progress to nephrotic syndrome, a condition characterized by massive edema, heavy proteinura and peculiar susceptibility to infections that break into and modify the course of any pre-existing disease. 12.Mercury fillings can contribute to a higher level of mercury in the blood. 13. Mercury adversely affects the functioning of the heart. In many cases the vascular response to norepinepherine and potassium chloride is blocked by the presence of mercury compounds. Mercury also blocks the entry of calcium ions into the cytoplasm. 14. Exposure to mercury compounds has been found to increase cardiovascular impairment. 15. Electrocardiograph (ECG) readings are abnormal in cases of organic mercurial poisoning. 16. A study in 1983 reported that chronic mercury exposure in rats led to interference with catecholamine (adrenaline, epinephrine, dopamine, norepinephrine) reactivity levels. 17. Mercury appears to have a pronounced effect on the endocrine system. Endocrine substances are excreted by various glands in the body, and these glands control or influence almost all of the body processes. Some of the endrocrine secretions are hormones (steroids, peptides, and amino acids). The steroid and peptide hormones have a half-life varying from 5 to 100 minutes and circulate in the blood plasma. Some of the glands that excrete endocrine sybstances are the pituitary, thyroid, adrenals, parathyroid, pancreas, gonads, pineal body and the paraganglia. Research indicates that the pituitary and thyroid glands display an amazing affinity for the accumulation of mercury. Concentrations of mercury in the pituitary and thyroid glands were much higher than that found in the kidney, brain or liver tissues in humans. Evidence seems to indicate a drastic decrease in the production of thyroid hormones when mercury is in evidence. Low mercury concentations result in hormonal shifts and thyroid dysfunction. 18. The thyroid gland will absorb an increasing amount of nuclear radiation from all sources under the influence of the presence of mercury. 19. Animals poisoned with methyl mercury exhibit stress intolerance and decreased sexual activity. The data indicates impairment of the adrenal and testicular steroid hormone secretions. The level of mercury in tissue required to cause the endocrine abnormalities is lower than those levels associated with overt neurological dysfunction. 20. Methyl mercury is known to diminish sexual activity in birds and mammals. It also causes subnormal fertility and spermatogenesis (sperm production) in rats and impaired growth. 21. Mercury can produce contact demititis and Addison’s disease (reduced function of the adrenal glands. Some of the symptoms are progressive anemia, low blood pressure, diarrhea and disgestive disturbances. 22. Mercury has distinct effects on the immune system, especially the white blood cells (leukocytes) referred to as lymphocytes, of which there are two types, T cells and B cells. T-cells are produced in the thymus gland and B-cells are thought to be produced in the bone marrow. High frequencies of chromosomal aberrations have been observed in lymphocytes exposed to mercury ions. In other words, the presence of mercury alters the genetic code in the immune system. Other effects of mercury on white blood cells include chromosomal breakage, alteration of mitosis (cell reproduction) and death of white blood cells, as well as a drop in T-cell production. 23. Methyl mercury has an injurious effect on the fetal nervous system even at levels far below that considered to be toxic in adults. The concentration of methyl mercury in fetal blood is about 20% higher than that of the mother. Still births and the incidence of fetal birth defects exhibit positive correlation with background levels of mercury. 24. Symptoms of congenital disease from methyl mercury include: intelligence distinclude: intelligence disturbances, primative reflexes, disturbances in body growth, speech difficulties, limb deformity, and hyperkinesia (hyperactivity resulting from brain damage). Abnormally small heads and mental retardation were 25. During the 1971 incident in Iraq where mothers were exposed to methyl mercury through contaminated food, mothers were studied for a five year period following the exposure. Defects in babies whose mother had been exposed to methyl mercury included CNS damage, cerebral palsy, a greater death rate among babies, delayed mental development, delayed motor development, small head circumference, exaggeration of reflexes and delayed speech development. 26. The reaction of adults during the 1971 Iraqi incident included headache, sleep disturbances, dizziness, irritability, emotional instability, mania and depression. Mercury binding compounds did not seem to have an effect in enhancing recovery from depressive states caused by mercury toxicity.
