正交设计银翘散抗流感病毒作用的实验研究

目的 通过对银翘散各配伍与抗流感病毒药效之间关系来探讨其配伍规律.方法 用流感病毒滴鼻造成小鼠感染模型,以小鼠肺组织中病毒的血凝滴度作为观察指标,运用正交设计方法 ,观察银翘散各配伍与药效之间的关系.结果 银翘散降低流感病毒感染小鼠肺组织匀浆血凝滴度的必要因素有连翘、金银花、牛蒡子、荆芥穗、竹叶、生甘草、桔梗、薄荷,而淡豆豉的作用不明显（P＞0.05）.连翘与金银花、连翘与牛蒡子、连翘与荆芥穗、牛蒡子与薄荷、荆芥穗与桔梗有交互作用.结论 从降低流感病毒滴鼻感染小鼠肺组织匀浆血凝滴度的角度看,银翘散最佳组合为连翘2,金银花2,牛蒡子2,荆芥穗1,竹叶2,生甘草2,桔梗1,薄荷2,淡豆豉1.

Experimental study on anti-influenza virus infection with Yinqiao-decoction by orthogonal design

Objective To investigate composition principle of Yinqiao-decoction through experiment of anti-influenza. Methods The effects of different compositions of Yinqiao-decoction on the index of hemagglutinin titre of virus in the lung tissue of mice infected with virus from nose were investigated by orthogonal design. Results According to the hemagglutinin titre of virus in the lung tissue of mice, the necessary effective drugs of Yinqiao-decoction are forsythia suspense, flos lonicerae, fructus arctii,schizonepeta tenuifolia, folium phyilostach lophatheri, glycyrrhiza uralensis, platycodon grandiflorum and mentha haplocalyx, and semen sojae preparatum isn't necessary. There is interaction between forsythia suspense and flos lonicerae, forsythia suspense and fructus arctii, forsythia suspense and schizonepeta tenuifolia, fructus arctii and mentha haplocalyx, schizonepeta tenuifolia and platycodon grandiflorum.Conclusion The optimal combination of Yinqiao-decoction is flos lonicerae, forsythia suspense, fructus arctii, folium phyllostach lophatheri, glycyrrhiza uralensis, mentha haplocalyx of the second level and schizonepeta tenuifolia, platycodon grandiflorum, semen sojae preparatum of the first level.
