黄体主要分泌孕酮,孕酮对黄体功能具有直接的调节作用。除孕酮外,黄休内还含有很高浓度的花生四烯酸,具有大量合成前列腺素(PG)的能力。近年来,有关 PG 在调节黄体功能方面的重要性已引起了重视,研究的内容主要集中于黄体 PG的合成与调节及其对黄体功能的作用。有人认为,来源于黄体的 PG 与黄体的生成和退化有关,而黄体 PG 的合成可能受孕酮调节。本文研究的目的在于探讨孕酮对黄体 PG 合成的影响。实验采用具有正常动情周期的奶牛,于动情期 Progesterone is mainly secreted by the corpus luteum and progesterone has a direct regulatory effect on corpus luteum function. In addition to progesterone, Huang Huo also contains a very high concentration of arachidonic acid, with a large number of synthetic prostaglandins (PG) capacity. In recent years, the importance of PG in regulating the function of corpus luteum has drawn great attention. The contents of the research mainly focus on the synthesis and regulation of corpus luteum PG and its effect on corpus luteum function. It is thought that PG derived from the corpus luteum is associated with the formation and degradation of the corpus luteum, while the synthesis of the corpus luteum PG may be regulated by progesterone. The purpose of this study is to investigate the effect of progesterone on the synthesis of luteinized PG. Experiments with normal estrous cycle of cows, during estrus
