耳蜗钾循环对维持正常听觉生理功能具有重要作用。耳蜗钾循环途径中涉及诸多离子通道,本文就其中的Na K2Cl联合转运子(NKCC)1与听觉生理关系的研究进展综述如下。耳蜗内淋巴具有类似细胞内液的离子成分,即高K+低Na+。内淋巴中存在一个+80～+100mV的耳蜗内电位(endocochlearpote
The cochlear potassium cycle plays an important role in maintaining normal auditory physiological function. There are many ion channels involved in the cycle of the cochlea potassium circulation. The progress of the study on the relationship between the Na 2 ClCl transporter (NKCC) 1 and auditory physiology is summarized as follows. Cochlear endolymph has a similar intracellular fluid ion composition, that is, high K + low Na +. Endolymphatic there is a +80 ~ +100 mV in the cochlear potential (endocochlearpote
