ANALYSIS OF ELEMENTAL ABSORPTION AND EXCRETION IN MICE BEARING MALIGNANT ASCITES

Feces, kidney, and small intestine were sampled from the mice bearing malignant ascites at different stages of tumor growth to investigate t he kinetics of elemental distribution in the body. The contents of 14 elements in samples were determined by instrumental neutron activation analysis (INAA). The elements Br, Cl, Cu, Na, Se, and Zn increased, w hereas Mn and Rb decreased in kidney with the growth of the tumor. The elements Cl, Na, and Fe, however, appeared to have significantly diff erent behavior in the small intestine.
