验证如下假设 :在胞质分裂阻滞细胞中辐射诱发微核(MN)的多少是细胞辐射敏感性大小的表现 ,所以 ,辐射敏感细胞将有高的 MN率 ,而辐射抗性细胞将显示较低水平的MN率。方法 :1用辐射敏感性大不相同的 13种神经元细胞系进行实验。其中人成神经细胞瘤有 N2 α、SHSY5 Y、SK- N-SH
Validation of the hypothesis is that how much of the radiation-induced micronuclei (MN) in cytokinin-retarded cells is a manifestation of the magnitude of cellular radiation sensitivity so that the radiation-sensitive cells will have a high MN rate while the radiation-resistant cells will show more Low level of MN rate. Methods: 1 Experiments were performed with 13 neuronal cell lines of widely differing radiosensitivity. Among them, there are N2 α, SHSY5 Y and SK-N-SH in human neuroblastoma
