稀土作业者外周血淋巴细胞姊妹染色单体互换的观察

OBSERVATION ON PERIPHERAL BOOOD lYMPHATIC SISTER CHORMATION EXCHANGES OF RARE-EARTH WORKERS

本文报告了 5 0例稀土作业工人外周血淋巴细胞姊妹染色单体互换 (SCE)的观察结果 ,其 SCE频率为 5 .49± 1.2 1(SCE/ cell,X+ SE) ,与 2 0例对照组相比 ,差异显莉 (P<0 .0 1)。随工令的延长 ,SCE频率为增高的趋势 ,但各工令组之间 ,经统计学处理 ,差异不显著 (P<0 .0 5 )。男工 SCE率高于女工 ,这可能与男工吸烟人数多于女工有前。我们认为

The peripheral blood lymphcyte sister chromatid exchanges(SCE)of 50 rare-earth workers were reported,The frequency of SCE was 5.49±1.21(SCE cell±SE).There was statistical significent difference(P<0.01)as compared with 20 individuals in control group.It appeared a tendency that the freguency of SCE increased with the length of service,but with no statistical difference(P<00.5)between different length of service.The frequency of SCE in male was higher than that in female.Perhaps this is associated with more cigarette smoking in male than in female.It is considered that the SCE would be the monitoring index in the early danger to rare-earth workers.
