Abstract
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.
摘要
研究了局部X射线照射对艾氏腹水癌细胞中钠离子跨膜转运及钠钾ATP酶活性的影响。结果显示，0.05和0.15 C/kg剂量的照射会改变钠离子转运。而0.08 C/kg剂量时则无此效应。在相同辐射剂量下，主动转运速率的变化在一定程度上与钠钾ATP酶的紊乱相关。
