A study was made of the effect of ionizing radiation on mitotic cycle and survival of the Chinese hamster cells of two clones-CHLV-79 RJK, and its derivative Vebr-30, resistant to ethidium bromide. Ethidium bromide resistant cells were more resistant to 1) lethal effects of gamma rays (by cell survival); 2) X-rays (by cell cycle recovery after irradiation of cells in a dose of 5 Gr); 3) colcemide treatment (by accumulation of cells in G2+M phase). These data may result from damaging a certain regulatory process, which may be involved in cell response to radiation damage and in repair of predominantly sublethal and partly lethal DNA lesions as well as of cell membrane structures.
对电离辐射对两个克隆的中国仓鼠细胞（CHLV - 79 RJK及其抗溴化乙锭的衍生物Vebr - 30）的有丝分裂周期和存活的影响进行了研究。抗溴化乙锭的细胞对以下方面更具抗性：1）γ射线的致死效应（通过细胞存活情况）；2）X射线（通过对5格雷剂量照射的细胞进行细胞周期恢复情况）；3）秋水仙酰胺处理（通过细胞在G2 + M期的积累）。这些数据可能源于破坏了某个特定的调节过程，该过程可能参与细胞对辐射损伤的反应以及对主要是亚致死和部分致死的DNA损伤以及细胞膜结构的修复。
