摘要 目的探讨马拉硫磷对雄性小鼠生殖细胞的毒性效应。方法将健康昆明种雄性小鼠随机分为4组,对照组不放入马拉硫磷,其余3组为染毒组,分别以高(5.19 mg/m3)、中(3.91 mg/m3)、低剂量(2.36 mg/m3)马拉硫磷静式吸入染毒小鼠,于染毒后90 d剖检,观察马拉硫磷对小鼠精子畸形率的影响。结果各染毒组精子畸形率增高,高、中剂量组分别与对照组比较,差异均有统计学意义(P<0.01),低剂量组与对照组比较差异无统计学意义(P>0.05);随着染毒剂量的增加,精子畸形率逐渐增加,两者呈正相关(r=0.97,P<0.05)。结论长期吸入一定浓度的马拉硫磷对动物细胞具有致突变性,对雄性生殖细胞具有潜在的诱变危害。
