【摘要】 本实验用双电极法记录了25只家兔阴道平滑肌的电活动,观察了人绒毛膜促性腺激素(hCG)和乙酰胆硷(ACh)的影响。主要结果如下:1、hCG可促进阴道肌细胞兴奋的同步化,从而形成爆发波。2、ACh对阴道平滑肌有兴奋效应。3、hCG对ACh的兴奋效应有增强作用。4、子宫和阴道的运动各自独立。结果提示胆碱能神经在阴道活动的调节中可能有一定的作用。更多还原

【Abstract】 Electrical activities of the vaginal muscle in 25 rabbits were recorded by using bipolar electrtode technique. The effects of hCG and ACh were observed. The results are as follows: (1) hCG could promote synchronization of the excitations and burst electrical activities of the vaginal muscle. (2) The effect of ACh on vaginal muscle was excitatory. (3) The exciting effect of ACh could be enhanced by hCG. (4) The movements of the uterus and the vagina were independent with each other. The result suggested that cholinergic nerves may have a functional role in the regulation of motility of vagina.更多还原
