The Cl- activity in the endolymph of the endolymphatic sac and in the cochlear duct was measured with Cl- sensitive double-barreled microelectrodes. The Cl- activity in the endolymphatic sac fluid was lower than in the cochlear duct. A small, positive, DC potential was recorded in the endolymphatic sac. During anoxia, the DC potential decreased while the Cl- activity in the endolymphatic sac increased. The K/Na ratio in the epithelial cells and subepithelial tissue of endolymphatic sac was measured using the LAMMA technique. The K/Na ratio in the epithelial cells decreased after ethacrynic acid injection (60 mg/kg i.v.). These findings suggest that chloride in the endolymphatic sac is actively transported inward and outward.
使用氯离子敏感双管微电极测量内淋巴囊内淋巴和蜗管内淋巴中的氯离子活性。内淋巴囊液中的氯离子活性低于蜗管中的氯离子活性。在内淋巴囊中记录到一个小的正直流电位。缺氧时,直流电位降低,而内淋巴囊中氯离子活性增加。使用激光微探针质谱分析法(LAMMA技术)测量内淋巴囊上皮细胞和上皮下组织中的钾/钠比。注射依他尼酸(60毫克/千克静脉注射)后,上皮细胞中的钾/钠比降低。这些发现表明,内淋巴囊中的氯离子被主动地向内和向外转运。
