[The morphological characteristics of sarcoma M1 cells before and after irradiation]

Morphology of the death of rat sarcoma M1, cells before and in varying time after irradiation at doses of 10 and 20 Gy with and without metronidazole (as a radiosensitizer) was investigated at the light optic and electron microscopic levels. Two types of death: necrosis and apoptosis with the prevalence of the former were revealed. Irradiation and the use of metronidazole did not influence the type of death of sarcoma M1 cells.
