摘要
结果表明乌鸡黑素对诱变物质DNMP引起的大肠杆菌WP_2B/r(uvrA ̄-,trp ̄-)的突变频率有明显的抑制作用;并显著降低了受诱变剂4NQO作用的大肠杆菌GC4415细胞内β-半乳糖苷酶的活性。
The melanin isolated from white
silk fowls was ogserved to be effective for reducing the mutagenic
activity of Es-cherichia coli WP_2B/r(uvrA ̄-trp ̄-)induced by
mutagen DNMP ,and also capable of decreasing the activity of β
-galac-tosidase in the cells of E,coli GC 4415 affected by another
mutagen 4NQO.
