调研209名氯乙烯(VC)作业工人的细胞遗传学指标,平均工龄48.3个月,年龄18～67岁,1968～1975年间接触VC的时间加权均值为1～5ppm(VC中含小量致变性的氯亚乙烯)。295名“雇前体检者”充作对照组,年龄18～50岁。检测是采外周血样,进行淋巴细胞染色体计数。淋巴细胞培养采用Moorhead技术,以标准方法保温、处理和分析。两组皆记录性别、被分析的细胞数和培养开始起的日期。
A total of 209 VC workers were enrolled in this study. The average length of service was 48.3 months and ranged from 18 to 67 years. The time-weighted mean VC exposure from 1968 to 1975 was 1 to 5 ppm (a small amount of mutagenicity Of vinylidene chloride). 295 “pre-employment medical examination” as the control group, aged 18 to 50 years old. Detection is taken peripheral blood samples for lymphocyte chromosome counts. Lymphocyte culture is Moorhead technology, insulated, processed and analyzed by standard methods. Both groups recorded the sex, the number of cells analyzed, and the date the culture started.
