摘　　要：目的:探索刚离乳幼龄大鼠的中药非临床安全性评价方法,观察小儿风叶咳喘平合剂4周灌胃给药对幼龄SD大鼠的毒性反应,为儿童临床用药提供参考。方法:刚离乳SD大鼠120只,按体重随机分为4组,每组30只,雌雄各半,分为溶媒对照组,风叶咳喘平合剂低(浸膏7.0 g·kg^(-1))、中(浸膏14.0g·kg^(-1))和高(浸膏22.5 g·kg^(-1))剂量组;各剂量组动物每天灌胃给药1次,PND21开始给药,共4周,溶媒对照组给予等量的去离子水;检测一般状况、体重、摄食量、生长发育、血液学、血液生化学、凝血、尿液、免疫、激素、脏器和病理组织学变化。结果:高剂量组雌雄幼龄大鼠体重降低、摄食量减少、血液学指标(网织红细胞计数RET和RET%增加)、脏器重量或系数(胸腺减轻、肝脏增加)有所改变;雄性幼龄大鼠生长发育迟缓,表现为雄鼠顶臀长减少,胫骨长缩短、胫骨总密度和皮质密度增加;未见明显毒性靶器官;上述表现对雄性幼龄大鼠的影响更加明显。结论:幼龄SD大鼠4周灌胃给予风叶咳喘平合剂的安全剂量为浸膏7.0 g·kg^(-1)(低剂量,相当于生药量79.8 g·kg^(-1)),为大鼠等效剂量的2.5倍,临床剂量的14.9倍。Objective: To explore the non-clinical safety evaluation method of Traditional Chinese medicine in juvenile rats,and observe the 4-week toxicity of Children Fengye Kechuanping Mixture,so as to provide reference for clinical medication in children. Methods: A total of 120 juvenile SD rats were randomly divided into 4 groups according to bodyweight,with 30 rats in each group,half male and half female. Four groups were solvent control group,Children Fengye Kechuanping Mixture low( extract 7. 0 g·kg^(-1)),medium( extract 14. 0 g·kg^(-1)) and high( extract 22. 5 g·kg^(-1)) dose groups. Each group was given the medication once a day by gavage. PND21 were given for 4 weeks in total,and the solvent control group was given the same amount of deionized water. General status,bodyweight,food intake,growth and development,hematology,blood biochemistry,coagulation,urine,immunity,hormones,organs and histopathological changes were detected. Results: In high-dose group,the weight,food intake,hematological indexes( RET,RET% increase),organ weight or coefficient( thymus decrease,liver increase) changed. Growth retardation was observed in male juvenile rats( manifested as decreased top hip length,shortened tibia length,increased tibia total density and cortex density). No obvious toxic target organs were observed. The effect of the above expression in juvenile male rats was more obvious. Conclusion: The safe dose of Children Fengye Kechuanping Mixture was 7. 0 g·kg^(-1)( low dose,equivalent to raw dose 79. 8 g·kg^(-1)),2. 5 times of the equivalent dose and 14. 9 times of the clinical dose in juvenile SD rats given by gavage for 4 weeks.
