摘要: 检测水蛭素冻干粉的致畸性。 方法: 将60只妊娠大鼠随机分为水蛭素冻干粉(每克含3 mg、相当于50 抗凝血酶单位的天然水蛭素)312.5、1 250、5 000 mg/kg 3个剂量组,同时设蒸馏水阴性对照和阿司匹林(300 mg/kg )阳性对照组,共5组,每组12只。各组孕鼠于妊娠第6~15 天灌胃给予受试物,每天1次,连续灌胃10 d,于妊娠第20天解剖孕鼠,检查胎鼠外观、内脏和骨骼及生长发育等指标。 结果: 水蛭素冻干粉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 > 0.05),未见胎鼠外观、内脏和骨骼发育异常及畸形。 结论: 水蛭素冻干粉在本实验条件下,对大鼠无母体毒性、胚胎毒性和致畸性。

Abstract: To determine the potentially teratogenic effects of lyophilized hirudin powder in rats. METHODS: Sixty pregnant rats were divided randomly into 5 groups, 3 groups treated with lyophilized hirudin powder (contain 3 mg which was equivalent to 50 AT-U natural hirudin per gram) with doses of 312.5, 1 250, 5 000 mg/kg, one negative control(distilled water) and a positive control(300 mg/kg aspirin), 12 pregnant rats in each group. The drugs were given orally for 10 days from 6th to 15th day after gestation. At 20th day the rats were sacrificed to examine the appearance, viscera, bones and physical growth of the fetuses. RESULTS: The body weight of pregnant rats, litter weight, live birth rate, fetal body weight and length in all treated groups were not significantly different from negative control group(P > 0.05), and no abnormality of organ or appearance was observed in the fetuses of treated groups. CONCLUSION: Lyophilized hirudin powder had no maternal toxicity,embryo toxicity and teratogenicity in rats at doses tested.
