Variation of Se, Zn, Co, Fe and Rb distribution in rats after injection with selenium or sulfur compounds.

Contents of Se, Zn, Co, Fe and Rb in liver, kidney, heart, spleen, brain, pancreas and testicle of Wistar rats were determined 2 h after i.p. injection with selenodiglutathione, selenomethionine, selenocystine, selenocystamine, methionine, cystine and cystamine. Instrumental neutron activation analysis (INAA) was applied as the analytical method. It was found that Se was incorporated to all examined rat organs. High Se incorporation was observed after injection with selenomethionine and selenocystine. Variations in the Zn, Co, Fe and Rb contents were observed in all the investigated organs after the injections. These variations depended upon injected compounds.
