Results In three Hank's solution infused cochleas, the thresholds of IC potential were kept in the normal level and no hair cell loss was found 14 days after the beginning of the infusion, suggested that the pump implantation and Hank's solution infusion had no significant effects on the cochlear functions. In contrast, threshold shifts of IC potentials and hair cell loss were found in two BSO infused animals, suggested that the infused solution had distributed into the whole cochlea.

结果 应用渗透压泵耳蜗灌流Hank液后，下丘电位阈值维持正常，耳蜗毛细胞无损伤；灌流BSO液14天后，所测频率(1、 2、 4和8 kHz)的下丘电位阈值平均升高28 dB，内耳毛细胞平均缺失39.3%，缺失分布于耳蜗各回，表明渗透压泵工作良好。
