摘要
目的 考察WHPI的急性毒性作用。方法 按中药新药毒理学研究指南的要求与方法,用SPF级昆明小鼠以腹腔注射、尾静脉注射两种给药途径进行了WHPI的急性毒性试验,用Bliss法计算其半数致死量(Lethal Dose50,LD50)。结果 受试物腹腔注射给药对昆明小鼠的LD50为30.0764(28.73~31.66)mg/kg,尾静脉注射给药的LD50为71.4490(68.54~74.17)mg/kg。结论 WHPI给昆明小鼠腹腔注射比静脉注射毒性高。这可能是WHPI经肝代谢后产物毒性比静脉注射时高,提示临床上宜采用静脉注射途径。
Objective To study the acute toxicity of WHPI on KM mice. Methods Determinating it's lethal dose 50 (LD50) by means of Bliss's method. Results LD50 is 71.4490(68.54 ~74.17)mg/kg with i. v, LD50 of WHPI is 30,0764(28.73~31.66)mg/kg on KM mice with i.p, while its Conclusion The acute toxicity of WHPI on KM mice with i.p is stronger than that with i.v. which suggests that it should be i.v in the clinics.
