The incidence of sister chromatid exchanges in smokers and nonsmokers was investigated. There was no difference in the SCE rate between smokers and nonsmokers, nor was there any difference between heavy (greater than 10 per day) and light (less than 10 per day) smokers.
对吸烟者和不吸烟者的姐妹染色单体交换发生率进行了调查。吸烟者和不吸烟者之间的SCE率没有差异,重度吸烟者(每天超过10支)和轻度吸烟者(每天少于10支)之间也没有差异。
