我们对40名正常人外周血淋巴细胞姐妹染色单体互换(SCE)自发频率进行了研究。结果计数800个中期细胞,观察36,800条染色体,共有4,097次SCE。本研究用最终浓度10微克/毫升BrdU浓度,每个细胞SCE平均值为5.121±1.82,结果与吴旻等报告的BrdU为3微克时SCE频率5.76±0.42及吴玉清等报
We studied the spontaneous frequency of sister chromatid exchange (SCE) in 40 normal human peripheral blood lymphocytes. Results 800 metaphase cells were counted and 36,800 chromosomes were observed with a total of 4,097 SCEs. In this study, the final concentration of BrdU concentration of 10 micrograms / ml, the average value of each cell SCE was 5.121 ± 1.82, results and Wu Min and other reports of BrdU of 3 micrograms SCE frequency of 5.76 ± 0.42 and Wu Yuqing et al
