摘要: 本文通过MNNG作用于xylE-ICR 转基因小鼠,按1/ 10LD50给药,每天1 次,连续5d ,最后一次给药后21d ,测小鼠肝组织突变率为21. 46 ×10 - 5 ,与对照组( < 4. 38 ×10 - 5) 比相差极其显著( P < 0. 01) ,表明该检测方法可作为规范化程序,对诱变物进行致突变研究的系统分析。

Abstract: Allow MNNG administ ration in the xylE2ICR t ransgenic mice. We dosed for 5 days , then count survivors 21 days after the final dose. The result s showed : the spontaneous mutant f requency for xylE gene in the liver of xylE-ICR t ransgenic mice was much lower than the MNN G2induced mutant frequency. It is evident that the protocol could be used in the analysis of mutagenesis of chemicals.

Key words: transgenic mouse, mutagenesis, normalizing
