Abstract

目的 用3个遗传终点来研究接触甲氨喋呤(MTX)工人的遗传损伤.方法外周血分别来自21名生产MTX工人和21名对照组工人.用微核试验、彗星试验、hprt基因突变试验和TCR基因突变试验对两组人群进行检测.结果工人组平均微核率(MNR)、平均微核细胞率(MCR)分别为10.10‰±0.95‰和8.05‰±0.75‰,明显高于对照组(5.48‰±0.82‰和4.38‰±0.58‰),差异有统计学意义(P 0.05).工人组的hprt和TCR平均突变率分别为1.00‰±0.02‰和(6.87±0.52)×10-4,明显高于对照组[0.86‰±0.01‰和(1.67±0.14)×10-4],差异有统计学意义(P<0.01).结论生产MTX工人某种程度上存在遗传损伤。
