    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 A study of the precision by three methods of gamma-ray photopeak integration has been carried out. COVELL's, “total peak area” method and the proposed method have been considered. The latter was considered to be the most advantageous because of its relatively high precision and simplicity.

    Use of INAA to study the interaction between Ag and Se, Zn, Rb, Fe or Co in mice (1989)

    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 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 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.

    Use of neutron activation analysis for the determination of cesium in Pd electrodes on Pt and Au matrices (1995)

    Notes: Abstract A method of neutron activation analysis (NAA) for the determination of Cs inside a thin Pd electrode deposited on a Pt or Au matrix is reported. This simple and rapid method involves a post-irradiation radiochemical separation of Cs from high activities of interfering radionuclides. The separated Cs was determined by high resolution γ-ray spectrometry. The method allows the determination of Cs without a time-consuming cooling period. The radiochemical procedure (RNAA) is found to be relatively highly precise, sensitive, rapid and simple. Pre-irradiative chemical separation of Cs is likely to be reasonable.

    Notes: Abstract Male Swiss mice were injected intraperitoneally with indium ions and Se-compounds (viz. selenomethionine and SeO2). The distribution of Se, In and Zn in liver and spleen has been studied by instrumental neutron activation analysis. Se and In were incorporated in all investigated organs. The simultaneous injections with In and Se-compounds do not produce observable In−Se correlations effects. On the other hand, it was found that the simultaneous and single In injections increase the Zn-content in liver (24 h after injections), whereas no correlation effects were observed in spleen.

    A digital photopeak integration in activation analysis (1992)

    Notes: Abstract A study of the precision attainable by two methods of γ-ray photopeak computation has been carried out. The “total peak area” method (TPA) and the proposed new method have been compared. The method offered is digital and simulates repeatedly accumulations of γ-ray spectra. The method described here computes the apparent net peak area without a clear distinction between peak and non-peak related channels. The proposed method is considered to be the most advantageous because of its relatively high precision.

    Effect of selenium on the Hg, Zn, Fe and Co content of yeast cells (1992)

    Notes: Abstract The yeast cells, Saccharomyces cerevisiae, were exposed to Hg2+ ions (10−4M) and SeO2 (2·10−4−10−2M) or Se- methionine (2·10−4M). Instrumental neutron activation analysis (INAA) was used to analyze changes in the Hg, Zn, Fe and Co levels in these cells. When the yeast was incubated in a medium containing 10−3M and 10−2M SeO2, the Hg content of the yeast markedly increased. It was also found that the uptake of Se and Hg influenced the levels of Zn, Fe and Co found in the cells. While the presence of Se-methionine (Se-Met), SeO2 or Hg2+ ions caused increases in the intracellular Zn levels, the combined presence of Hg2+ and SeO2 and their assumed interaction, reduced the efficiency of Se for increasing the Zn content of yeast.

    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%.
