  • Title: [The interphase death of dividing cells. The effect of oxygen and the pH of the medium on the interphase death of Ehrlich ascites carcinoma cells under the action of ionizing radiation].

    Abstract:
    Interphase death of in vitro irradiated (200 Gy) Ehrlich ascites tumor cells was studied as a function of oxygenation level and medium pH. The presence of oxygen both during and after irradiation as well as the increase in pH from 7.4 to 8.1 were shown to increase interphase death rate. The pronounced threshold dependence of interphase death of cells upon their concentration may be attributed to hypoxia occurring in a pericellular medium when cells concentration exceeds the threshold.
