摘要
以优质蚕豆(Vicia faba)为试验材料,采用蚕豆根尖细胞微核测定技术,研究不同品牌(SJ染发膏、CY染发膏)、不同质量浓度(1.5、4.5、6.0、9.0、12.0、15.0g·L^(-1))的染发剂对蚕豆根尖细胞微核率的影响。结果表明:在一定浓度范围内,蚕豆根尖细胞微核率随染发剂浓度的升高而增加,当高于一定浓度后呈下降趋势,SJ染发膏、CY染发膏分别在9.0、6.0g·L^(-1)的质量浓度条件下诱导的蚕豆根尖细胞微核率最高,表现为对蚕豆根尖细胞严重的遗传损伤。该研究可以评价常用市售染发剂对植物细胞的遗传损伤,同时可为市售染发剂的安全使用提供参考。
Genotoxicities of commercial hair dyes manufactured by two companies(SJ and CY)were determined by the micronucleus assay on the root-tip cells of Vicia faba.Dye solutions in the concentrations of 1.5,4.5,6.0,9.0,12.0and 15.0g/L were applied for the test.The presence of micronuclei was shown increased after immersing the cells in the hair dye solutions.It increased with increasing concentration initially and followed by a decline for both products.With SJ,the peak number of micronuclei was observed at the dye concentration of 9.0g/L;and with CY,6.0g/L.Indicated by the rises of the micronucleus counts,there was apparently genomic damages to the plant cells caused by the hair dyes.It,therefore,implicated a safety concern on the products for consumers.
