title: [Combined use of radiosensitizing and protective agents in experimental radiotherapy].
abstract: The appropriateness of the combined use of electron acceptor radiosensitizers: 4-nitroimidazole and metronidazole, and sulfhydryl protectors WR-2721 (gammaphos) and cysteamine was shown on the Chinese hamster cells V-79 and transplantable mouse tumors. The administration of the sensitizer 30-60 min and the protector 15-20 min before the irradiation of solid tumors weakens radiation reactions of the skin (metronidazole plus gammaphos) without weakening the effect of radiosensitization on transplantable animal tumors (metronidazole plus gammaphos or 4-nitroimidazole plus WR-2721).
