Organ and subcellular distribution of selenium in rats exposed to cadmium, mercury, and selenium

Environmental Research, 1983
Three groups of rats were given sodium selenite (Se), sodium selenite and cadmium chloride (Se + Cd), or sodium selenite, cadmium chloride, and mercuric chloride (Se + Cd + Hg), respectively. All animals received subcutaneous doses of 115CdCl2 (0.3 mg Cd/kg) every other day for a fortnight. Mercuric chloride was administered intravenously at doses of 0.

[Selenium and the organism].

Casopis lekaru ceskych, 1999
Selenium is an essential trace element for animals. It is biologically active as selenocysteine in the active centre of selenoproteins with enzymatic functions. Incorporation of selenocysteine occurs on the basis of genetic expression and selenium is the only trace element under direct genetic control.

On the Chemical Radioprotection by Organic Selenium Compounds in Vivo

Radiation Research, 1969
This paper deals with the radioprotection afforded by selenocystine, selenomethionine, colloidal selenium, selenoxanthene, selenoxanthone, and selenochromone in living rats. Our evaluation of radioprotection was based on the ability of the compounds to alleviate the mortality and the leukopenia occurring in rats exposed to irradiation of 600, 750, and ...

Toxicity of organic and inorganic selenium to mallard ducklings

Archives of Environmental Contamination and Toxicology, 1988
The toxicity of selenomethionine and sodium selenite to mallard ducklings (Anas platyrhynchos) was measured by feeding each form from hatching to six weeks of age at dietary concentrations of 0, 10, 20, 40, and 80 ppm selenium. At 80 ppm selenium, sodium selenite caused 97.5% mortality by six weeks and selenomethionine caused 100% mortality. At 40 ppm,
