Effects of traces of rare earth elements on the protozoan Blepherisma and on mice.

abstract：:Arsenite has been known for half a century to have a protective effect against selenium poisoning. Paradoxically, arsenite inhibits the conversion of inorganic selenium salts to methylated excretory products, although methylation has long been regarded as a detoxification mechanism for selenium. Moreover, there is evi...
