研究了木尘作业工人外周血淋巴细胞微核率,并进行了相关因素分析。结果表明,木尘作业工人外周血淋巴细胞微核率超过2‰的有33.8％,而对照人群仅为4.8％,差别非常显著(P<0.01)。木工微核增高出现率随接触木尘浓度及工龄的增加有增加的趋势。吸烟与不吸烟者微核增高出现率无显著差异。
The micronucleus rate of peripheral blood lymphocytes in wood dust workers was studied and related factors were analyzed. The results showed that the micronucleus rate of peripheral blood lymphocytes in workers exposed to wood dust was 33.8%, which was only 4.8% of the control population, with a significant difference (P <0.01). Carpentry increased the incidence of micronucleus with exposure to dust concentration and increased length of service tends to increase. There was no significant difference in the incidence of micronuclei between smokers and non-smokers.
