摘　　要：本文应用组织化学和超微细胞化学方法显示碳酸酐酶（ＣＡＨ）在豚鼠血管纹（ＳＶ）和Ｃｏｒｔｉ器中的分布。光镜观察到ＳＶ和Ｃｏｒｔｉ器均含有丰富的ＣＡＨ，电镜观察到ＳＶ的边缘细胞和外毛细胞（ＯＨＣ）呈强阳性反应，ＳＶ的中间细胞和基底细胞、内毛细胞（ＩＨＣ）见到少量反应产物。结果表明耳蜗ＣＡＨ的分布与其功能有密切关系。Abstract The distribution of carbonic anhydrase activity in the cochlea of guinea pigs were stud-ied with histochemical and ultrastructal cytochemical method. Reaction products were found both in the stria vascularis and Corti’ s organ with light microscope. Very strong reaction products were found in the marginal cells of stria vascularis and outer hair cells. Weak reac-tion products were observed in the intermediate cells,basal cells and inner hair cells. The re-sult shows that carbonic anhydrase distribution in cochlea is colsely asssociated with it’s function.
