title: [Radiosensitizing and toxic action of metronidazole and isometronidazole (1-(2-hydroxyethyl)-2-methyl-4-nitroimidazole) on the cells of Ehrlich ascites cancer and hemoblastosis La in vitro].
abstract: A study was made of Ehrlich ascites tumor growth and life span of mice bearing hemoblastosis La after inoculation of tumor cells subjected, in anaerobic conditions, to the effect of gamma-radiation and/or metronidazole and isometronidazole. It was shown that the cytotoxic effect of isometronidazole was less manifest than that of metronidazole the radiosensitizing effect, with a reference to anoxic tumor cells in vitro, being nearly the same.
