Methods Pregnant rats were gavaged castor oil-diet in 18 and 19 days of gestation. At the time of death, blood of portal and peripheral veins, intestinal mucosa, amnion, amniotic cells and placenta were collected, and the tissues were cultured in the presences of ricinoleic acid or indomethacin.

将妊娠18天的Wistar大鼠分实验组和对照组各8只，实验组大鼠每天两次灌服引产餐，灌服4次后剖杀大鼠，收集门静脉、末梢血，胎盘、羊膜组织及制备羊膜细胞进行体外培养。

The increased synthesis of PGE2 in the intrauterine tissues is a key of the initination of labor induced by castor oil-diet, and ricinoleic acid in castor oil-diet might be the active component which induced the initiator of labor.

蓖麻油引产餐引起宫内组织PGE2合成变化是其引产的关键，而蓖麻酸可能是蓖麻油引产餐的活性成分。

Two multifunctional agent, glycidyl methacrylate and refined ricinoleic acid , were adopted to modify EPDM in situ during compounding and vulcanization process. The effects of the modifiers on vulcanization behavior, processiability, different properties of the vulcanizates were investigated.

为此，选择了含有极性基团的多官能团小分子改性剂甲基丙烯酸缩水甘油酯和精制蓖麻油酸，在橡胶混炼和硫化过程中对EPDM进行原位改性，研究了原位反应技术对过氧化物硫化EPDM橡胶的反应特性、加工性能、力学性能、热性能、耐老化性能、耐屈挠疲劳性能及与金属的粘合强度等性能的影响，并探讨了其改性的机理。

Results The PGE2 levels in the portal vein increased, while the PGE2 levels in peripheral blood had no changes significantly, the PGE2 levels in the tissues of the intestinal mucosa, placenta, amnion and amniotic cells were increased significantly; Ricinoleic acid stimulated the synthesis of PGE2 in the above tissues invitro, which had the positive correlations with the dose of ricinoleic acid and its lasting time.

结果 实验组大鼠门静脉PGE2水平升高，外周血PGE2水平无变化；实验组大鼠肠粘膜、胎盘、羊膜组织和羊膜细胞PGE2合成明显升高；蓖麻酸刺激肠粘膜、胎盘、羊膜等组织和细胞PGE2合成，其刺激合成能力与蓖麻酸浓度及其作用时间呈正相关。
