Objective To observe the effects of cholinergic agonists on intracellular calcium concentration ( [ Ca 2+] I) of isolated vestibular hair cells ( VHC) from the guinea pig and the effects of gentamicin on it.

目的通过观察胆碱能受体激动剂对离体前庭毛细胞内钙离子浓度的影响，以探讨前庭毛细胞膜所存在的胆碱能受体分型及庆大霉素对钙离子通道的阻断作用。

Postoperative regurgitation, stenosis, and immune rejection occur, lead to a pipeline of early loss of power, need to double or multiple surgeries to replace the VHC.

术后常因发生反流、狭窄及免疫排斥而导致管道早期失功，需二次或多次手术更换VHC。
