[The effect of membrane-active compounds on the radiation-modifying effect of glucose in x-irradiated ascitic tumor cells].

A study was made of the influence of membrane-active agents with different mechanisms of action (quercetin, amiloride, valinomycin, and digitonin), that modify the transmembrane transfer of inorganic ions, on a modifying effect of a glucose loading in X-irradiated Ehrlich ascites tumor cells. The combination of digitonin with glucose increased the damaging effect of radiation on tumor cells by 1.8-2.2 times as compared to glucose alone. Merely insignificant changes in the radiation-modifying effect of glucose were observed when it was combined with other membrane-active agents.
