摘要: 目的:用Ames 试验、小鼠骨髓嗜多染红细胞微核试验、人体外周血淋巴细胞姐妹染色单体交换(SCE) 试验以及小鼠精子畸形试验对重质芳烃进行了致突变性研究。结果:重质芳烃无移码突变和碱基置换效应,微核试验显示在316~1 580 mg/ kg·bw 剂量范围小鼠骨髓嗜多染红细胞微核率显著增加(与阴性对照组比较P < 0. 01) ;SCE 试验结果显示在活化系统(S9 混合) 存在的条件下,人外周血淋巴细胞SCE 频率较对照组显著增高(在0. 5 mg/ ml 及5 mg/ ml 剂量组) ;小鼠精子畸形试验显示在1 580 mg/ kg·bw 剂量水平小鼠精子畸形率显著增高,与阴性对照组比较差异有显著性( P < 0. 01) 。结论:重质芳烃具有间接致突变性,对其职业性接触及应用的安全性应给予高度重视。

Abstract: Purpose and Methods : The mutagenicity of heavyweight aromatic hydrocarbon (HAH) was studied by Ames test , micronucleus test and sperm deformity test in mice , sister chromatid exchange test in human beings. Results : Ames test was negative in all dosage groups. The f requencies of bone marrow micronucleus were increased significantly at the dose of 316~1 580 mg/ kg·bw. The result of SCE showed that the f requencies of SCE in two groups (0. 5 mg/ ml and 5. 0 mg/ ml) were significantly increased. In mouse spermatic deformity test , the rate of spermatic deformity was statistically higher at 1 580 mg/ kg·bw than that of negative group.Conclusion : HAH has potential mutagenicity for somatic cells in mice and human being , and for sperm in mice.We should pay attention to it s occupational exposure and it s application.

Key words: heavyweight aromatic hydrocarbon, Ames test, micronucleus, Sister chromatid exchange, spermdeformity
