递增负荷运动大鼠卵巢子宫超微结构变化及其恢复过程观察

众所周知,女性性腺卵巢通过周期性分泌女性激素,调控和影响女性生殖系统的功能,维持规律的月经周期。在长期大运动量作用影响下,女运动员出现以低性腺类固醇和低促性腺皮质激素水平为特征的适应性反应,进而导致AMI的高发病率1,2,3,4]。为了阐释AMI的病理机制,搞清训练影响下HP

Effects of structure changes on functions in rats' ovary and uterus during the progressive increasing load training and recovery course

The purpose of this experiment was to explore the potential mechanisms of effects of structure changes on functions in rats' ovary and uterus during progressive increasing training load and recovery courses.Transmission and scan electron microscope were used to observe the tissue ultrastructure.The shape,integrity and conjunction of epithelium were markedly changed in ovarian.Nuclear membrane breaked,mitochondria became vacuole,endoplasmic reticulum dilated,and lysosome increased in follicular theca interna cells and granular cells.The epithelium of endometrium may find: microvilli on cells decreased from lightness to seriousness,cell membrane breaked,organelles were abnormal,which indicated synthesizing function was inhibited,and cell mature was restrained,so that endometrium were in diestrus.These changes were consistent in lower sex hormones level,estrous cycle dysfunction in the same phase.The structure changes of rats' ovary and uterus were progressively recovered after 4 estrous cycles rest.
