本文作者最近曾报道过印度楝树油(neemoil)作为一种杀精子剂,在大鼠、恒河猴及人类体内、外的作用效果。小规模预试提示该药可能有抗着床作用,因此作者研究了楝树油的抗着床效应及其后遗作用。本文首次报告这一研究结果。采用72只同种系性周期规则的雌性wistar大鼠(重约125～150g)为实验对象。实验组66只,再分为Ⅰ-Ⅲ三小组,分别于交配后第2～4、4～6、 The authors recently reported the effects of neemolil as a spermicide in and out of rats, rhesus monkeys and humans. Small-scale pre-tests suggest that the drug may have anti-implantation effects, so the authors studied the anti-implantation effect of neem oil and its consequences. This article first reports the results of this study. A total of 72 female wistar rats (weighing about 125-150 g) were used as experimental subjects. The experimental group of 66, then divided into Ⅰ-Ⅲ three sub-groups, respectively, after mating 2 ~ 4 ~ 6,
