[Effect of ionizing radiation on the membrane potential and electrical input resistance of Chinese hamster fibroblast membranes].
X-irradiation with a dose of 8 Gy leads to a sharp decrease in membrane potential of cultured Chinese hamster cells followed by restoration thereof. Changes in the membrane potential are accompanied by a monotonous increase of mean values of input cell resistance. It is assumed that radiation elicits a decrease in the resistance of a plasma membrane and a concurrent increase in the resistance of intercellular gap contacts which lead to impairment of cell interaction.
