[Modification of the action of ionizing radiation on cells of transplantable tumors by administering xanthobine].

In experiments on mice it was established that the radiosensitizing effect of xanthobin was manifested by the enhancement of the inhibiting action of ionizing radiation on the growth of adenocarcinoma RL-67, diminution of the "shoulder" of the survival curve of Ehrlich ascites tumor cells, and increase in the average life of tumor-bearing animals.
