摘要: 背景与目的: 探讨检测育发剂致突变性的适宜的方法。 材料与方法: 运用Ames试验、小鼠淋巴瘤细胞试验(MLA)对3种育发剂的致突变性进行研究。 结果: 28种育发剂中有85.72%的样品对组氨酸缺陷型鼠伤寒沙门氏菌均有程度不同的抑菌或杀菌作用,选取的3种育发剂对组氨酸缺陷型鼠伤寒沙门氏菌均有较强的抑菌杀菌作用,在试验浓度下均未呈现致突变性;MLA试验结果显示,1号样品和3号样品育发剂在测试浓度下未呈现致突变性;2号样品育发剂随浓度增大,L5178Y细胞TK位点的突变频率有升高的趋势,其中8 μl/ml、40 μl/ml和200 μl/ml剂量组的突变率,与对照组相比差异有统计学意义 (P<0.05)。 结论: 小鼠淋巴瘤细胞试验(MLA)可做为毒性较大育发剂的遗传毒性筛检的补充试验。

Abstract: BACKGROUND & AIM: To investigate suitable methods for detecting mutagenicity of hair restorers. MATERIALS AND METHODS: Using Ames test and mouse lymphoma assay (MLA) to evaluate the mutagenic effects of three kinds of hair restorers. RESULTS: Three hair restorers had strong bacteriostatic and bacteriocidal effects on Salmonella typhimurium, and no mutagenicity was observed. In MLA test, sample No.1 and sample No.3 had no mutagenic effects at concentrations tested, However, in No.2 hair restorer, TK locus mutation frequency was significantly higher than that of control group (P<0.05)at high dose. CONCLUSION: MLA test may be a complementary method used to detect the mutagenic effect of hair restorer.
