Tellurium is used industrially for thermoelectric apparatuses and in the process of creating rubber. It is also used medically and as a coloring for glass(Cobalt). Another use is as a gasoline additive to reduce engine knock. It is an additive to steel ot improve machinability. It helps control the depth of chill in cast (iron). It is used in the chemical industry as an additive. It has been found as a telluride in cow's milk. It binds with copper and zinc and manganese. It has been found in food to prevent botulism. It may be absorbed through the skin. It binds with N-Methyl or dimethylamine. Elevated N-Methyl (R)Salsolinol is involved in the pathogenesis of Parkinsons Disease. Tellurium possibly causes malformations in human babies. It binds with tretinoin as does N-Methyl and tretinoin causes genetic birth defects. Symptoms of toxicity are garlic breath, sweating, dry mouth, a metallic taste, somnolence, anorexia, nausea, no sweating (it says so) ,dermatitis in humans and in animals, central nervous system damage and red blood cell changes. It is interesting that chronic myelogenic leukemia, like Parkinsons, is from an environmental cause of a genetic illness, both involve Bcr or breakpoint clusters and tretinoin. Leukemia results when cobalt is effected, or bound up. Without enough cobalt there is not enough cobalamin which is needed for leukocytes to mature. Leukemia has an overproduction of immature leukocytes, and anemia which may have to do with red blood cell changes. Telluride can be turned into tellurium by the gram positive bacilli that make N-methyl during the fermentation of food in your stomach. I just wonder if the tellurium along with the N-Methyl are getting into the body and binding the iron somehow, or whatever metal it can find. Methylamine binds with the melanin to form an aldehyde, like formaldehyde, and (R)Salsolinol is formed from dopamine combining with this aldehyde. This leaves less dopamine available and would cause Parkinsons. The aldehyde I read could also be produced from too much iron in a cell. Methylamine binds tubulin that is found in Lewy Bodies. Airline Stewardesses that have a mysterious Parkinson's like illness complain of a metallic taste and an unusual rash. Tellurium is also used to bind metallic coins. Anybody know anything about tellurium or can you find any studies of this substance and parkinsons disease, or ALS, or ALzheimers, or Leukemia, or Multiple Sclerosis, or Pagets Disease, or Bone Cancer or Tumor Growth? It seems metallothioneins are involved in ALS and in Cisplatin that is the retinoid cis or tretinoin and the metal platinol. It seems metaloproteinases are elevated in Alzheimers, Leukemia, Multiple Sclerosis, Pagets Disease and Cancer. Thanks Jim and Sharon
