Changes in oxidative stress intensity in blood of tumor-bearing rats following different modes of administration of rhenium-platinum system [Text] = Зміни інтенсивності оксидативного стресу крові щурів-пухлиноносіїв за введення системи реній-платина різними способами / K.

A decrease in the concentration of TBA-active substances caused by dirhenium compounds was shown to be independent of the administration mode and the extent of the tumor growth inhibition. I was four-times more effective in inhibition of the LP burst than any known antioxidant. I induced the increasing activity of erythrocyte superoxide dismutase and decreasing activity of catalase. In vitro experiments with native superoxide dismutase, the interaction ofІ with following activation of the active center of the enzyme was confirmed and the superoxide dismutase activity of І was shown, that may contribute to the enhancement of the enzyme activity in vivo. The cluster rhenium compounds may be promising nontoxic potent antioxidants capable of deactivating superoxide radicals Доп.точки доступа: Shamelashvili, K. L.; Shtemenko, N. I.; Leus, І.
