摘要: 摘要: 目的 筛选培育眼部突变表型小鼠,为人类相关疾病的研究提供材料。方法 采用 N-乙基-N-亚硝基脲 ( N-ethyl-N-nitrosourea,ENU) 诱变处理 G0 代小鼠,繁育获得 G1 代,筛选眼部突变表型个体,进行遗传力试验、临床 诊断及病理学观察。结果 本实验繁殖 G1 代小鼠 2782 只,经筛查获得眼部突变表型小鼠 65 只,可稳定遗传小鼠 3 例,分别表现为: 角膜混浊、小眼球和虹膜异常等特征。角膜混浊者其角膜症状严重程度差异较大,角膜病变部位 明显增厚,部分伴有新生血管; 小眼球者睑裂较小,甚至上下眼睑粘连,外观眼球不可见,病理学检查可见内有发育 异常的小眼球; 虹膜异常者可见瞳孔偏大,明显偏离中心位置,偏向位置不定,对光无反射,病理学观察可见虹膜晶 状体粘连、虹膜缺损,严重者伴有视网膜异常等。结论 本实验成功培育了 3 例眼部突变表型小鼠,为人类相关疾 病的研究提供良好的材料。

Abstract: Abstract: In order to obtain materials of eye-mutant mice for human eye related diseases research,generation zero ( G0) mice were mutagenized by N-ethyl-N-nitrosourea ( ENU) ,and G1 generation mice were bred and selected for eye mutant phenotype. All mice were proceeded heritabilitytest,clinical diagnosis and pathological observation respectively. A total of 2782 mice were bred and 65 eye mutants were screened,in which,three cases mice were inheritable,and congenital corneal opacity,nanophthalmos and iris malformation were its phenotypic characteristic respectively. Corneal opacity turbidity was fairly different,especially in terms of hyperplasia and new angiogenesis. The phenotypic traits of nanophthalmos mice was blepharophimosis,blepharosymphysis,and the eyeball was invisible ( severe,general inspection) ,but dysplastic nanophthalmos was visible ( pathological observation) . The phenotypic characteristic of iris malformation was found that the pupil was larger,obvious deviation from the central location,and no light reflection,irido-lens adhesions,collyriculum iridis,retina abnormality ea tl. Three cases of ENU-induced eye mutant mice were bred successfully and lay a foundation for human eye disease research.
