    Notes: Abstract Male SAS/4 mice injected intraperitoneally with chromate ions and Se-compounds (i.e. selenodiglutathione, selenocystine, selenomethionine and SeO2). The distribution of Se, Cr, Zn, Rb, Co and Fe in liver, kidneys, spleen, heart, lungs, blood, small intestine and eyes has been studied by instrumental neutron activation analysis. Cr was incorporated in all investigated organs and the efficiency of the Cr-accumulation was affected upon the Se-injection. It was found that the mutual and indirect interaction occurs between injected Se-compounds and chromate ions. On the other hand, the interaction of Cr with Zn has been competitive. Injection with chromate ions affects the contents of Rb, Co and Fe in mice organs.

    Notes: Abstract 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.

    Notes: Abstract The incorporation of Se and Te into liver, kidneys, heart, spleen, lung and small intestine after i.p. injections of Balby mice with seleno-cystine (CySe)2 and Na2TeO3 in the presence of Cd (as CdCl2), As (as As2O3) and Zn (as ZnSO4) has been studied. The change of contents of Co, Fe, Rb and Hg were determined in all investigated organs after injections with the above compounds. Instrumental neutron activation analysis was applied as the analytical method. It was found that a competitive interaction occurs between As and Se or Te. Similarly, this interaction has been observed between Se and Cd. The data obtained suggest that Cd has a higher competitive ability to displace Te than Zn and Se. Injection with the above compounds affects the contents of Fe, Co, Rb and Hg in all mice organs.

    Notes: Abstract The incorporation of Se into some mice organs after injections of seleno-cystamine [(Se-Cta)2] in the presence of glutathione, cysteine, methionine, cysteamine, 6-mercaptopurine, 2-mercaptopurine and UO 2 2+ has been studied. Variations in the Zn, Rb, Co, Fe and Hg contents were determined in all examined organs after intraperitoneal injections with the above compounds. Instrumental neutron activation analysis was applied as the analytical method. It was found that injected compounds affect the Se-distribution in the organs examined. Single applied intraperitoneal injection of (Se-Cta)2 or UO 2 2+ lead to variations in the Zn, Rb, Co, Fe and Hg contents in mice organs.

    Notes: Abstract The reaction of platinum-methionines and platinum-selenomethionine complexes with ytterbium chloride was studied. The biodistribution of these organic platinum complexes labelled with169Yb was examined in animals bearing Ehrlich tumor. It was found that the retention of radioactivity from labelled monomethionin- and monoselenomethioninplatinum complexes in animals after 72 h was about 60% while the retention from dimethioninplatinum complex was about 6%.

    Notes: Abstract The incorporation of Se or Te into some mice organs after injections with selenodiglutathione [(GS)2 Se], seleno-cystine [(CySe)2] or Na2TeO3 in the presence of glutathione (GSH) or cysteine (CySH) has been studied. Variations in the Hg, Zn, Fe, Co, and Rb contents were determined in all the investigated organs after intraperitoneal injections with the above compounds. Instrumental neutron activation analysis was applied as the analytical method. It was found that GSH and CySH increased the Se-content in the organs after the injection with (CySe)2, whereas GSH decreased after (GS)2 Se supply. GSH and CySH changed also the Te distribution. Injections with the above compounds affect the Hg, Zn, Fe, Co and Rb concentrations and these variations depend upon the injected compounds.

    Notes: Abstract The contents of Se, Fe, Co, Zn and Rb in several organs of Swiss mice were determined by instrumental neutron activation analysis (INAA) after injections with seleno-methionine (Se-Met) and glutathione (GSH). Se was accumulated in all examined organs and significant effects of the treatment with GSH on the distribution of Se were observed. An increase of Zn (or Se) content in blood after injection with Se-Met (or Zn2+ ions) was observed.

    Notes: Abstract The interaction of inorganic mercury (as HgCl2) with SeO2 and organic Se-compounds is compared. Instrumental neutron activation analysis (INAA) was applied as the analytical method. Organ concentrations of Hg and Se were always significantly higher after simultaneous i. p. injections with HgCl2 and Se-compounds. Especially high abundances of Se and Hg in mice organs were found after simultaneous injection with Se-methionine and HgCl2. We suggest that Hg2+ ions are bonded by selenohydryl groups of the metabolites of injected Se-compounds. Binding yield of Hg2+ ions with metabolites of Se-compounds depends upon the chemical form of injected Se-compounds. Variations in the content of Zn, Co, Fe and Rb were observed in all the investigated organs after a single injection with HgCl2 or Se-compounds. Simultaneous injection with HgCl2 and Se-compounds affects the contents of these elements in comparison with single injections.

    Notes: Abstract The concentration of platinum in various organs of mice and rat was determined, after injection of tetrachloroplatinate and dichlorodimethioninoplatinum/II/, by neutron activation analysis. It was found that these two platinum complexes have a different biodistribution pattern in animals.

    Notes: Abstract Neutron activation analysis (NAA) for the determination of some trace elements in biological materials is described. The method presented permits the simple and rapid determination of Se, Ag, Au, Sb, Pt (via199Au), Hg, Co, Ni (via58Co), Fe, Zn, Mo, Sn, Cr, Cd, Cu and As after radiochemical separation from Na, K, Cs, Rb and partially Br. For this purpose, postirradiation separation by extraction with mercury or zinc amalgam was used. Separation of gold by extraction with ethyl acetate or by precipitation with dimethylglyoxime was applied for the determination of gold and platinum in biological materials.
