[Modifying effect of ionizing radiation on the transmembrane transport of sodium ions in Ehrlich carcinoma tumor cells].

The effect of a local X-irradiation on the transmembrane transfer of Na ions and activity of Na-K ATPase in Ehrlich ascites tumor cells has been investigated. Irradiation with doses of 0.05 and 0.15 C/kg are shown to change natrium ion transport. This effect is absent at a dose of 0.08 C/kg. A change in the rate of active transport correlates to some extent with the disturbance in Na-K ATPase occurring at the same radiation doses.
