A potential difference across mouse ovarian follicle

Summary A small potential difference (antrum positive) has been measured with fine-tipped glass microelectrodes across the epithelial cell layers of the mouse ovarian follicle wall. As ovulation approached the potential in the antrum became more positive compared to the outside. Metabolic inhibitors and locally active hormones also altered the potential difference. The ionic basis and the significance of the potential difference are unknown.     

B超监测卵泡发育与排卵在不孕症中的应用分析

B超监测卵泡发育与排卵具有直观性好、重复性强、便于连续检查等优点，是目前监测卵泡发育的重要手段。本文对32例B超监测与排卵的情况，结合基础体温测定、宫颈粘液譬晶情况分析，讨论了B超监测卵泡发育与排卵的独特优势，对黄体化卵泡不破裂综合症的诊断意义和临床治疗不孕症中指导用药、提高受孕率，以及在人工授精中的特殊意义。     

彩色多普勒血流显像在不孕症卵泡监测中的应用

通过对不孕症者30例,累计共45个月的月经周期的观察,将其患者分为对照组、服用克罗米芬组,并分别于月经周期第7d、10d、14d,对停服克罗米芬后第2d～4d、5d～7d的排卵前测量子宫内膜厚度、卵泡直径、子宫动脉的阻力指数(RI)、搏动指数(PI) 结果发现两组中见生长卵泡者为第41个月月经周期,卵泡检出率为91.11% 卵泡发育良好者,子宫内膜厚度与卵泡直径之间有密切相关性 同时可测得子宫动脉的血流参数,排卵前RI、PI的下降趋势.因此,CDFI检查为无侵害并易为患者所接受的监测和预测排卵的可靠方法
