摘要:

目的:检测红丝线草的致畸性。方法:红丝线草提取液设10.0、5.0、2.5 g/kg 3个剂量组,同时以去离子水作阴性对照,阿司匹林(0.3 g/kg)作阳性对照。每组12只SD孕鼠,受孕6 d开始按10 mL/kg给孕鼠灌胃受试溶液,每天1次,至受孕15 d,共灌胃10次。于妊娠 20 d解剖孕鼠,检查胎鼠的身体、外观、内脏及骨骼发育等指标。结果:红丝线草各剂量组的孕鼠体质量、窝质量、胎鼠体质量、身长、尾长、活胎率、吸收胎率及死胎率与阴性对照组比较差异均无统计学意义(P均>0.05),未见胎鼠外观、内脏和骨骼发育异常及畸形。结论:在本实验条件下,红丝线草对大鼠无母体毒性、胚胎毒性和致畸性。

Abstract:

OBJECTIVE: To determine the teratogenic effects of peristrophe roxburghiana (Schult.) brem in rats. METHODS:Pregnant rats were divided into 5 groups,each with 12 rats. Three groups were treated orally with exract from peristrophe roxburghiana for 10 days from 6th to 15th day of pregnancy with doses of 10.0,5.0,2.5 g/kg. The other two groups were fed orally with deionized water as negative control and aspirin with 0.3 g/kg as positive control. At 20th day,the rats were sacrificed to allow physical examination of the fetuses. RESULTS:In all treated groups the body weight of parental rats, litter weight, live rate, fetus body weight and fetus length were not significantly different from negative control group (P>0.05),and no abnormality of organ or external was found in the fetuses. CONCLUSION:In these experimental conditions,peristrophe roxburghiana had no appearance maternal toxicity,embryo toxicity nor teratogenicity in rats.
