Abstract
The influence of ionizing radiation (5.16 C/kg) on passive and active Na+ and K+ transfer within the giant neurons of edible snail (Helix pomatia) has been investigated. It has been shown that ionizing radiation increases passive permeability of membranes, inhibits active ion transport, changes the number and the affinity of functionally active Na+,K+-ATPase molecules. The authors discuss the mechanisms of action of ionizing radiation.
摘要
研究了电离辐射（5.16 C/kg）对食用蜗牛（玛瑙螺）巨型神经元内被动和主动的钠钾转运的影响。结果表明，电离辐射会增加细胞膜的被动通透性，抑制主动离子转运，改变功能活跃的钠钾ATP酶分子的数量和亲和力。作者讨论了电离辐射的作用机制。
