title: [75Se]selenite and [75Se]selenate fluctuations during the development of murine hepatoma.
abstract: The distribution of selenate and selenite selenium in C57L/J mice during the progression of BW7756 murine hepatoma was investigated using intra-ocular injection with the oxyanions labeled with 75Se radioisotope. Comparison is made with the normal distribution of selenium studied by the RIXRF method. The trace elemental profiles, TEP, for the two oxidation states are compared in healthy and disease states. It has been found that the presence of tumor significantly changes the level of tracer in various uninvolved organs. These changes are prominent in the early growth phase of the tumor. The two oxidation states show differences in the TEP for kidney, spleen, stomach and testes.
