补血生乳颗粒对SD大鼠围产期毒性

Toxicity of Buxue Shengru Granules on perinatal rats

目的通过观察不同剂量的补血生乳颗粒(黄芪、当归、白芍,等)用于围产期孕鼠后对大鼠及仔鼠的影响,探讨其对妊娠的安全性。方法 SD大鼠96只,随机分为4组,每组24只。设1个溶剂对照组(蒸馏水)和补血生乳颗粒低、中、高3个给药组,各组均于妊娠期第15天开始给药,连续给药至哺乳期结束,给药途径为灌胃,每天1次。于哺乳期结束处死母鼠解剖观察,观察指标包括母鼠一般状况、体质量及摄食量,仔鼠出生后,观察仔鼠外观有无异常,检测仔鼠生理发育、反射发育、行为及生殖功能等。结果补血生乳颗粒对围产期大鼠的一般状况、生育仔鼠的时间、体质量、各脏器系数等没有显著的影响;对仔鼠的生长、发育、神经、内分泌、生殖系统等没有显著的影响。结论补血生乳颗粒对母鼠的体质量增长及摄食量没有影响,对F1仔鼠的生理、反射发育、行为和学习记忆及生殖功能等无影响。补血生乳颗粒无围产期毒性作用。

AIM To investigate the toxicity of Buxue Shengru Granules(BSG,Astragali Radix,Angelicae sinensis Radix,Paeoniae Radix alba,etc.)to perinatal SD rats and their offspring to determine its safety.METHODS The respective BSG administration of 0,1,3,10 g/kg to the four groups rats,each with twenty-four female rats,started from the day 15 of gestation(GD15)through weaning when they were procured for the identification of the general condition,body weight and food ingestion.The offspring had their postnatal appearance observed the physiological development,reflexes development,behavior and fertility detected as well.RESULTS BSG gave neither significant influence on the rats'general condition,time of birth,body weight,and histological changes of organs during perinatal period;nor remarkable impact on the offspring,s growth,development,nerves,endocrine,and reproductive system.CONCLUSION Data on BSG to rats maternal weight gain and food intake and to their offspring developmental landmarks,sexual maturation,or reflexes suggest that BSG gives no perinatal toxicity.
