Effect of administration sequence of mercuric chloride and sodium selenite on their fates and toxicities in mice. 1984

A Naganuma, and Y Ishii, and N Imura

Interaction of mercury and selenium was examined in mice given mercuric chloride (25 mumol/kg) intravenously with sodium selenite (25 mumol/kg, iv) according to various administration schedules. Body weight of the mice given mercuric chloride or selenite alone did not increase, but the mice given both compounds simultaneously grew as well as control mice. On the other hand, only a 1-hr shift of administration of either compound canceled the mutual detoxifying effect. The most conspicuous changes in tissue distribution of mercury and selenium and in gel filtration patterns of both elements accumulating in tissues of the mice were observed when both compounds were administered simultaneously. These experimental results indicate that the interaction of mercuric mercury with selenite in mice occurred to the greatest extent upon simultaneous administration, supporting the hypothesis that the interaction primarily occurs in the blood stream.

D008627	Mercuric Chloride	Mercury chloride (HgCl2). A highly toxic compound that volatizes slightly at ordinary temperature and appreciably at 100 degrees C. It is corrosive to mucous membranes and used as a topical antiseptic and disinfectant.

D008628	Mercury	A silver metallic element that exists as a liquid at room temperature. It has the atomic symbol Hg (from hydrargyrum, liquid silver), atomic number 80, and atomic weight 200.59. Mercury is used in many industrial applications and its salts have been employed therapeutically as purgatives, antisyphilitics, disinfectants, and astringents. It can be absorbed through the skin and mucous membranes which leads to MERCURY POISONING. Because of its toxicity, the clinical use of mercury and mercurials is diminishing.
D008631	Mercury Radioisotopes	Unstable isotopes of mercury that decay or disintegrate emitting radiation. Hg atoms with atomic weights 185-195, 197, 203, 205, and 206 are radioactive mercury isotopes.	Radioisotopes, Mercury

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
