Selenium protection from cadmium and chromium poisoning

Abstract: The interaction of selenium with cadmium and chromium was studied in 168 chicken-broilers (DWCxWR) divided into four equal groups Eight-week old control animals received an intravenous dose of /sup 115m/Cd Chloride 370 KBq/Kg (Group I), or /sup 51/Cr Chloride 370 KBq/Kg (Group II) The kinetics of these isotopes were studied by scintillation spectrometry (NaI/TI) carried out for whole blood, plasma, plasma proteins, urine, feces and homogenates of all organs at various time intervals Animals in Groups III and IV received eight subcutaneous doses of sodium selenate (5ug) at 8-week intervals prior to /sup 115m/Cd or /sup 51/Cr The kinetics of these elements were studied as in the previous two groups It was found that selenium affected those kinetics in two ways: (a) by increasing the excretion of Cd by 11 +/- 3% (P < 0001) and that of Cr by 7 +/- 1% (P < 0001); and (b) by favoring redistribution of those elements, with significant (P < 0001) reductions in liver, endocrine glands and kidney and increases (P < 001) in bone The study suggests that selenium protects the animals' vital organs from environmental pollutants, such as cadmium and chromium
