摘要: 目的: 检测一种染发剂的致突变性作为毒理学评价的一部分。方法:用Ames 试验和体外哺乳动物细胞(CHL) 染色体畸变试验来检测氧化型染发剂的致突变性。结果:在加S9mix条件下,每皿2 500μg 至5 000μg 对测试菌株TA98 具有明显的诱变性,其回变菌落数是自发回变数的2~3 倍, Ames 试验检测结果为阳性。体外哺乳动物细胞(CHL) 染色体畸变试验显示在加或不加S9mix条件下,当受试物终浓度为300μg/ ml ,600μg/ ml 和1 000μg/ ml ,除了300μg/ ml 在加S9mix时染色体畸变细胞率未显著增加外( P > 0105) ,其余浓度无论加或不加S9mix ,染色体畸变细胞率与阴性对照组相比均有显著性差异( P < 0105) 。结论:受试的氧化型染发剂具有一定的遗传毒性。

Abstract: Purpose : To study the mutagenicity for a hair dye as a part of toxicological evaluation. Methods : The Ames test and chromosome aberration test in vitro in CHL cells were used. Results : At the dose of 2 500μg/ plate to 5 000 μg/ plate with the S9mix , the sample can induce the mutation of the strain TA98 , the number of reverse mutation bacteria clone was 2~3 times higher than the number of spontaneous mutation bacteria clone. CHL cell chromosome aberration test showed that at the concentration of 300μg/ ml without the S9mix , and at concentration of 600μg / ml and 1 000μg/ml with or without the S9mix , the sample can induce the chromosome aberration. The rate of chromosome aberration in treated group was significantly higher than that in the negative control group. Conclusion : The oxidative hair dye tested has certain genetic toxicity.
