本研究用40只Wistar大白鼠制作运动性闭经某些性激素分泌特点的动物模型.发现:长时间的力竭性运动可以使大白鼠动情周期产生抑制,并且其血清E_2和P浓度低于正常动情周期鼠的动情间期水平;提供外源性雌激素和孕酮可能对推迟或抑制运动性闭经的产生作用不大;动情周期抑制鼠的E_2和P浓度改变,且其阴道细胞涂片与运动性闭经女运动员相似.我们可以用大白鼠做进一步的研究.(英文简写:P——孕酮,E_2——雌二醇,FSH——促卵泡成熟素,LH——促黄体生成素) In this study, 40 Wistar rats were used to make animal models of the secretion of some sex hormones during exercise amenorrhoea.It was found that prolonged exhaustive exercise could inhibit the estrous cycle of rats and lower the serum E_2 and P concentrations than the normal estrus Period estrus interval; providing exogenous estrogen and progesterone may delay or inhibit the production of exercise amenorrhea little effect; estrous cycle inhibition of E_2 and P concentrations in rats, and the vaginal smears and exercise Sexual amenorrhea female athletes are similar.We can use the rat for further study (English abbreviation: P-- progesterone, E_2-- estradiol, FSH-- follicle-stimulating hormone, LH-- luteinizing hormone)
