摘要
目的 :探讨豚鼠耳蜗各回外毛细胞 (OHC)的分离方法。方法 :选豚鼠 8只 ,解剖耳蜗各回组织 ,获得Corti器并采用酶消化后机械分离。结果 :各回均可获得一定数量、活性良好的 OHC,第 1、2、3、4回单离 OHC的长度依次为 2 3.81、34.5 0、6 0 .48和 71.37μm。结论 :熟悉耳蜗各回解剖、组织特性并按操作要点进行是成功分离出各回 OHC的关键。
Objective:To probe the method of isolating outer hair cells (OHC) from each of four turns of the guinea pig cochlea. Method:From eight guinea pigs the organ of Corti from each of four turns of the cochlea were dissected, and then treated using enzyme. Result:A fair amount of living OHCs from each of four turns were obtained. The length of OHCs from each of four turns were 23.81 , 34.50 , 60.48 and 71.37 μm. Conclusion:The key to success in isolating OHCs from each of four turns of the cochlea is to know very well the anatomical characteristics of each of four turns of the cochlea and be operated in accordance with normal rules.
