摘要: 目的 通过幼龄SD大鼠急性毒性和长期毒性试验,评价薏芽健脾凝胶的安全性和对生长发育的影响。方法 急性毒性试验采用最大耐受量法,幼龄SD大鼠以最大给药量5.2 g·kg-1灌胃给药,每日2次,总给药剂量为10.4 g·kg-1,给药后严密观察大鼠的毒性反应情况。长期毒性试验采用幼龄SD大鼠200只,分为给药高(3.9 g·kg-1)、中(2.6 g·kg-1)、低(1.3 g·kg-1)剂量组和对照组,每组50只大鼠,连续给药90 d,恢复28 d,主要检查指标有体质量、摄食量、血液学、血液生化、生理发育、内分泌、神经行为学、病理等。结果 急性毒性试验幼龄SD大鼠灌胃薏芽健脾凝胶最大耐受剂量大于10.4 g·kg-1,且未见明显的毒副反应。长期毒性试验高剂量组(3.9 g·kg-1)部分指标出现一过性改变,未见与药物相关的毒性病理改变。结论 在本试验条件下,薏芽健脾凝胶对受试动物未见明显毒性反应。

Abstract: Objective To evaluate the safety of Yiya Jianpi jel and its effects on the growth of juvenile SD rats via acute toxicity and long-term toxicity tests. Methods The acute toxicity test was conducted using the maximum tolerable dose (MTD) method. The maximum dose was 5.2 g·kg-1, twice a day, and the total dose was 10.4 g·kg-1. After administration, the toxic reactions of rats were closely observed. The 200 juvenile SD rats used in the long-term toxicity test were divided into the high (3.9 g·kg-1), medium (2.6 g·kg-1), low (1.3 g·kg-1) dose groups and control group, with 50 rats in each. The drug was administered for ninety consecutive days before the rats were allowed to recover for twenty-eight days. The main indexes for examination were body mass, food intake, hematology, blood biochemistry, physiological development, endocrine, neuroethology and pathology. Results The MTD of Yiya Jianpi jel exceeded 10.4 g·kg-1 in juvenile SD rats, and no obvious side effects were observed. In the high dose group, transient changes were observed in some of the indexes during the long-term toxicity test, but no drug-related toxic pathological changes were observed (3.9 g·kg-1). Conclusion Under the conditions used in this experiment, Yiya Jianpi jel causes no obvious toxic reactions to the tested animals and clinical use in children is supported.
