Abstract

There were no significant changes in the activities of collagenase, acid and neutral protease up to ovulation. Neutral protease activity increased significantly in the post-ovulatory follicle obtained immediately after ovulation. Acid protease and collagenase showed an increasing activity with time after ovulation. The progesterone concentration of the follicle wall rose 3 h before ovulation, peaked 1 h before ovulation and remained high until ovulation. Plasma progesterone values were high but decreased before those in the follicle. Follicular progesterone concentrations decreased markedly soon after rupture, but oestradiol values then increased.

摘要

直至排卵时，胶原酶、酸性和中性蛋白酶的活性均无显著变化。排卵后立即获取的排卵后卵泡中，中性蛋白酶活性显著增加。酸性蛋白酶和胶原酶在排卵后的活性随时间增加。卵泡壁的孕酮浓度在排卵前3小时升高，在排卵前1小时达到峰值，并在排卵前一直保持较高水平。血浆孕酮值较高，但在卵泡中的孕酮值下降之前就开始下降。卵泡破裂后不久，卵泡孕酮浓度显著下降，但随后雌二醇值升高。
