[Combined effect of metronidazole, interferon synthesis inducers and DNA repair inhibitors].

In experiments on mice with solid sarcoma 37, a study was made of modification of the radiosensitizing effect of metronidazole. The increase in the leucotic interferon titre, induced by the interferon synthesis inductors, did not influence the radiosensitizing efficiency of metronidazole: after the administration of the repair inhibitor, 8-bromocaffeine, the coefficient of suppression of tumor growth was higher and the number of mice with the regressed tumors greater as compared to animals affected by metronidazole and radiation.
