为了探索姐妹染色单体互换(SCE)与苯作业工龄之间的关系,我们选64例苯作业工人为观察组。另选不接触苯的工人50例为对照组。两组均用常规方法培养和制作外周血淋巴细胞 SCE 片。
In order to explore the relationship between sister chromatid exchange (SCE) and benzene working length, we select 64 benzene workers as the observation group. Another 50 workers without exposure to benzene as the control group. Both groups were routinely cultured and produced peripheral blood lymphocytes SCE tablets.
