三一(2-甲基-1-氮丙啶)磷化氧(MAPO)是一种昆虫不育剂,在工业上亦有诸多用途。本文用CHO细胞微核试验、染色体畸变分析。SCE试验和CHO/HGPRT基因位点正向突变方法,分别在加S_9活化和非活化条件下检测了MAPO的致突变作用。在建立CHO/HGPRT位点正向突变试验
Trichlorethylene (2-methyl-1-aziridine) phosphine oxide (MAPO) is an insecticide and has many uses in industry. In this paper, CHO cell micronucleus test, chromosome aberration analysis. SCE test and CHO / HGPRT gene site forward mutagenesis method were detected under the activation of S_9 activation and non-activation of MAPO mutagenicity. In the establishment of CHO / HGPRT site forward mutation test
