1·In this paper, two new scant hair mice were obtained by ENU inducing and mutant genes were mapped on chromosome.

本文即用enu诱变获得了两例新的稀毛小鼠并对突变基因进行了染色体定位。

2·This review summarizes the approaches to ENU mutagenesis phenotype screens and their role in the identification of new deaf genes in recent years.

本文对近年采用ENU诱变表型筛选的方法和在确定新的耳聋基因中的作用进行概述。

3·One day after plating, the cells were exposed for 2 h to various doses of ethylnitrosourea (ENU). CAs and SCEs were examined by the standard methods, while CT was determined by cell counts.

接种细胞一天后，用不同剂量乙基亚硝基脲（ENU）处理2小时，然后用标准法检查其染色体畸变和SCE率，用细胞计数法测定细胞毒性。
