1. Alaskan Airline Stewardesses are coming down with s/s porphyria with a metallic taste. Tellurium causes a metalic taste and would inhibit porphyrin causing s/s porphyria. 2. Tellurium is an environmental toxin that is a potent mutagen. It could cause environmental Parkinsons disease and genetic Parkinsons disease. 3. Tellurium is not rare. It is used in antiknock additives of gasoline, used to vulcanize rubber and in the making of natural and synthetic rubbers. It is used in welding. It is used in insecticides, germicides, fungicides. It binds with N-Methyl which is elevated in Parkinsons disease. It binds with ethyl carbamate, benzene, which is linked to chronic myelogenic leukemia, a disease also looking for the environmental cause of a genetic illness. 4. All Parkinsons Diseases effect porphyrin and involve an increased in lipid peroxidation. Tellurium can take the place of sulphur in the Reiske iron cluster of Complex III of Mitochondrial Respiration and of the same cluster used by ferrochelatase that gives on iron ion to porphyrin. 5. Manganese Toxicity causes Parkinsons and inhibits iron from reaching ferrochelatase. Tellurium would inhibit ferrochelatase. MPTP pyridine inhibits porphyrin that is supposed to be accepting the iron ion from ferrochelatase. 6. Andrew J Larner in 1996 linked tellurium to Alzheimers disease. Alzheimers has problems with copper and rubber is vulcanized with copper-tellurium. 7. Cell death in Parkinsons Disease shows increased Fe3+ ferric iron, decreased complex I, decreased GSH levels. Tellurium inhibits Complex I and II and GSH. Fe3+ iron - Sulphur becomes Fe2+ - Sulphur. But tellurium is a sulphur-like metal that binds other metals. Fe3+ - tellurium could not become Fe2+ - tellurium. [log in to unmask]
