用微筛法4个终点检测了北京市3种染发剂和两种冷烫精的遗传毒性。实验程序见北医大学报(1992;1:42)。染发剂临用前按使用说明配成原液,冷烫精仅测冷烫剂部分。 实验结果呈良好的重现性。染发水G经代谢活化后,在1.56‰(V/V)浓度即可显著诱导溶原菌E.Coli
The genotoxicity of three kinds of hair dyes in Beijing and two kinds of cold scalders were detected by four end points of the microsieve method. The experimental procedures can be found in the Journal of Beijing Medical University (1992; 1:42). Before the hair dye is used, the original liquid is blended according to the instructions for use, and the cold flake essence only measures the cold flake portion. The experimental results showed good reproducibility. After metabolic activation of the hair dye G, the lysogen bacterium E.Coli can be significantly induced at a concentration of 1.56 ‰ (V/V).
