The effect of prostaglandins E2 and F2alpha on the contractility of the uterine cervix was investigated in nonpregnant women throughout the menstrual cycle. PGF2alpha was found stimulatory to the cervix at all phases of the menstrual cycle, whereas PGE2 was inhibitory. The relaxing effect of PGE2 was most marked during midcycle.
在整个月经周期对非妊娠女性研究了前列腺素E2和F2α对子宫颈收缩性的影响。发现在月经周期的所有阶段,PGF2α对子宫颈有刺激作用,而PGE2则有抑制作用。PGE2的舒张作用在月经周期中期最为明显。
