Use of INAA to study the interaction between Ag and Se,Zn, Rb,Fe or Co in mice

The interaction of inorganic silver (as AgNO₃) with SeO₂ and Se-compounds was studied. Instrumental neutron activation analysis (INAA) was applied as the analytical method. Organ concentrations of Ag were always significantly higher 72 hours after simultaneous intraperitoneal injections with AgNO₃ and Se-compounds. Moreover, simultaneous injections elevated the Se-content in organs examined. We suggest that Se-compounds protect against liver lesions by markedly decreasing the concentration of Ag in this organ 2 hours after simultaneous injections. It was also found that Ag supply affects the contents of Zn, Rb, Fe and Co.
