摘要:

背景:有研究显示蓖麻籽提取物具有一定的抗生育作用,然而国内对蓖麻籽在抗生育方面的报道很少。
目的:探讨蓖麻油引产餐提取物对大鼠子宫收缩和羊膜组织前列腺素E2含量的影响。
方法:选取60只Wistar未孕成年雌性大鼠,随机分为生理盐水组、缩宫素组及引产餐提取物组,各20只,观察并记录给药前后各组大鼠离体子宫的收缩强度、频率及活动力。选取90只妊娠18 d的Wistar成年雌性大鼠,随机分为生理盐水组、缩宫素组及引产餐提取物组,各30只,利用放射免疫方法测定给药后各组大鼠羊膜组织前列腺素E2水平。取生理盐水组大鼠羊膜组织,体外培养羊膜细胞,在培养液中加入不同质量浓度蓖麻酸,培养18 h,利用放射免疫方法测定羊膜细胞前列腺素E2水平。
结果与结论:与给药前及生理盐水组相比,给药后引产餐提取物组大鼠子宫的收缩强度、频率及活动力均明显提高,与缩宫素组相比,给药后引产餐提取物组大鼠子宫的收缩强度、频率差异无显著性意义(t=2.321,    P > 0.05),而活动力较低(t=2.765,P < 0.05);与生理盐水组相比,引产餐提取物组妊娠大鼠羊膜组织前列腺素E2水平显著增高(t=14.91,P < 0.01),但引产餐提取物组妊娠大鼠羊膜组织前列腺素E2水平低于缩宫素组(t=2.769,P < 0.05)。大鼠羊膜细胞前列腺素E2水平与蓖麻酸质量浓度及培养时间呈正相关。提示蓖麻油引产餐提取物能够增强宫缩效果、增加羊膜组织前列腺素E2水平,蓖麻酸可能是蓖麻油引产餐的活性成分。

Abstract:

BACKGROUND: Studies have shown that castor bean extract has certain anti-fertility effect; however, there are few reports in China about anti-fertility aspect of castor bean.
OBJECTIVE: To explore the effects of castor oil diet extract on uterine contraction of rats and the content of prostaglandin E2 in amniotic tissue.
METHODS: Sixty Wistar unfertilized adult female rats were selected and randomly divided into normal saline, oxytocin and castor oil diet extract group (n=20 rats/group). Before and after drug administration, contraction intensity, frequency and motility of isolated uterus of rats in each group were observed and recorded. Ninety Wistar adult female rats of gestation for 18 days were selected and randomly divided into normal saline, oxytocin and castor oil diet extract groups (n=30 rats/group). Prostaglandin E2 level in amniotic tissues of rats was measured by radioimmunoassay method. The amniotic tissue of rats in normal saline group was obtained. The amniotic cells were cultured in vitro by adding different concentrations of ricinoleic acid in the culture medium for 18 hours. Prostaglandin E2 level in amniotic cells was measured by radioimmunoassay method.
RESULTS AND CONCLUSION: Compared with before drug administration and normal saline group, contraction intensity, frequency and motility of isolated uterus of rats in castor oil diet extract group were significantly improved after administration. There were no significant differences in contraction intensity and frequency (t=2.321, P > 0.05) after drug administration between oxytoxin and castor oil diet extract groups, however, after drug administration, motility in the castor oil diet extract group was significantly lower (t=2.765, P < 0.05) than in the oxytoxin group. Compared with normal saline group, prostaglandin E2 level in amniotic tissues of pregnant rats in castor oil diet extract group was significantly higher (t=14.91, P < 0.01); however, prostaglandin E2 level in 
amniotic tissue of pregnant rats in the castor oil diet extract group was significantly lower than in the oxytocin group (t=2.769, P < 0.05). Prostaglandin E2 levels in amniotic cells of rats were positively correlated with ricinoleic acid concentration and culture time. These results suggested that castor oil diet extract can enhance contractions and increase prostaglandin E2 levels in amniotic tissue. Ricinoleic acid may be the active ingredient of castor oil diet to induce aboration.
