摘要: 目的 探讨荆防颗粒浸膏对动物胚胎-胎仔发育的影响,为其药用价值的进一步开发提供参考。 方法 112只受精雌鼠分为空白对照组和荆防颗粒浸膏高、中、低剂量(10、3、1 g·kg-1·d-1)组,每组28只。全部动物于妊娠第6天(GD6)开始给药,每天灌胃给药1次,连续给药至GD15,停药至GD20解剖检查。试验期间,每天观察动物一般状态,定期检测动物体质量和摄食量,解剖时计数卵巢黄体数量、检查着床数和活胎数,测量活胎顶臀长和尾长,检查活胎外观、内脏和骨骼。 结果 给药期间,动物未见异常体征变化;与空白对照组比较,荆防颗粒浸膏未引起大鼠体质量异常增长;母本动物受孕率、平均黄体数量和受精卵着床丢失率也未见异常改变;窝均活胎率、死胎率和吸收胎率,胎仔顶臀长和尾长也未见明显改变;未见受试物导致胎仔外观、内脏和骨骼畸形。 结论 荆防颗粒浸膏未见潜在的大鼠胚胎-胎仔发育毒性,无明显损害作用剂量(NOAEL)为10 g·kg-1·d-1

Abstract: Objective To explore the developmental toxicities of Jingfang granule extract on embryo-fetal of rats, so as to provide reference for the further development of its medicinal value. Methods Totally 112 fertilized rats were divided randomly into control group, Jingfang granule extract 1, 3, and 10 g·kg-1·d-1 groups, 28 in each group. Animals were intragastrical administered with Jingfang granule extract from day 6 of pregnancy (GD6) once daily;; Rats were treated until GD15 and sacrificed on GD20. The clinical manifestation of animals was observed every day during test period, feed take and bodyweight were detected regularly. Corpora lutea number, implantation number, and living fetus number were counted. Lengths of fetus Crown-Rump and tail were measured and the appearance, skeleton, and viscera of fetus were detected. Results With the exception, no apparent toxic reaction in pregnant animals was shown in all groups. Compared with control group, rats treated with Jingfang granule extract had no abnormal change on maternal pregnancy rate, average corpora lutea number, average implantation loss rate, and average living fetus rate, and likewise, average lengths of fetus Crown-Rump and tail were normal. Moreover, rats treated with Jingfang granule extract had no malformation in fetus appearance, skeleton, and viscera compared with vehicle control. Conclusion Jingfang granule extract has no potential developmental toxicities on embryo-fetal of rats. Under the experimental conditions, the no observed adverse effect level (NOAEL) of Jingfang granule extract on developmental toxicity of rats is 10 g·kg-1·d-1.
