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.

Abstract  

Studies with L-ascorbic acid as biological complexing agent have been performed to investigate its influence on the uptake and retention of the radionuclide of ytterbium in animals. The experimental results indicate that the retention of169Yb in the investigated organs of mice is affected when169YbCl3 is simultaneously administered to the animal with L-ascorbic acid. L-ascorbic acid has little or no effect on the169Yb excretion when it is pre- or post-169YbCl3 injected.

Abstract  

The concentration of Se and Yb in the livers, kidneys, spleens and pancreases of mice were determined after the injection of selenodiglutathione and ytterbium chloride (singly or together) by neutron activation analysis. Both Se and Yb were incorporated into all the investigated organs and subcellular liver fractions. The highest Se level was found in the liver and kidneys and the highest Yb level was found in the pancrease and spleen.
