摘要
目的观察牛黄解毒滴丸对小鼠的急性毒性和对大鼠90d长期毒性。方法取健康大鼠80只,完全随机分为对照组和小、中、大剂量组,各20只。对照组给等容量新制蒸馏水;小、中、大剂量组分别给予4.1、8.2、16.4g/kg牛黄解毒滴丸,上午定时空腹灌胃给药1次,连续给药3个月。采用小白鼠最大耐受量测定法和大鼠长期毒性试验进行研究。结果对小鼠灌胃给药的半数致死量〉9g/(kg·d),相当于临床用量的120倍;停药后24h大剂量组淋巴细胞高于对照组[(89±5)%比(84±4)%,P〈0.05],其他指标各组都在正常范围内;停药后2周,即恢复期,淋巴细胞即下降至正常范围内。停药后24h,中剂量组和高剂量组组大鼠的ALT、AST高于正常组[分别为(43±7)、(44±9)U/L比(35±9)U/L,(221±35)、(233±34)U/L比(197±35)U/L],停药后2周降至正常范围内。大鼠长期毒性试验对动物一般行为活动、体重增长和病理组织学检查等与对照组比较,差异均无统计学意义(P〉0.05)。结论牛黄解毒滴丸未见明显毒性,为临床安全用药提供了实验依据。
Objective To observe the acute and long-term toxicity of niuhuang jiedu dripping pill. Methods Maximum tolerence dose was determined on mice. Long-term(90 days) toxicity test was studied on rats. Results LDs0 of niuhuang jiedu dripping pill given orally was more than 9 g/( kg · d), and there was no obvious long-term toxicity in general conditions, peripheral blood picture, function of liver and kidney and pathological histology in rats. Conclusion Niuhuang jiedu dripping pill is safe.
