在检查吸烟,饮酒者的外周血淋巴细胞姐妹染色单体交换(SCE)时发现,对照组与三个观察组(轻吸烟组、重吸烟组与吸烟饮酒组)之间有非常显著差异,但是重吸烟组与吸烟饮酒之间无明显差异。对照组与三个观察组之间微核率无明显差异。本实验似乎提示:①在本实验条件下,吸烟可引起明显的SCE变化而微核率的变化不明显;②吸烟量大则SCE交换数增高;③吸烟与饮酒在SCE变异上未见明显的联合作用。
In examining the Sister Chromatid Exchange (SCE) of smokers and drinkers of peripheral blood lymphocytes, there was a very significant difference between the control group and the three observation groups (light smoking group, heavy smoking group and smoking drinking group), however There was no significant difference between heavy smoking group and smoking and drinking. There was no significant difference in micronucleus rate between the control group and the three observation groups. This experiment seems to suggest that: ① in this experimental conditions, smoking can cause a significant change in SCE and micronucleus rate changes was not obvious; ② large amount of smoking SCE exchange number increased; ③ smoking and drinking no significant SCE variation Joint action.
