前列腺素 E_2(以下简称 PGE_2)是一种天然的前列腺素,对中期引产(羊膜腔内和羊膜腔外给药法)和足月引产(口服法)的效用有明显的优越性。从计划生育出发,进行对 PGE_2抗早孕的药理研究,用药物代替吸宫,将更符合为广大劳动群众服务的方向。作为生物合成品 PGE_2的鉴定,我们配合化学纯度的分析,测定了样品,对几种离 Prostaglandin E_2 (hereinafter referred to as PGE_2) is a natural prostaglandin, which has obvious superiority to mid-term induction of labor (amniotic cavity and amniotic fluid administration) and full-term induction of labor (oral method). Starting from family planning, pharmacological studies on anti-early pregnancy PGE_2, with drugs instead of suction Palace, will be more in line with the direction of the majority of working people. As a biosynthetic product PGE_2 identification, we cooperate with the analysis of chemical purity, determination of the sample,
