银翘散和玉屏风颗粒对流感病毒感染鸡胚保护作用研究

Experimental Study on Protective Effect of Yinqiao Powder and Yupingfeng Granule on Influenza Virus Infected Chick Embryos

目的:比较银翘散和玉屏风颗粒以及联合应用二者对流感病毒感染鸡胚的保护作用。方法:通过测定培养后鸡胚的血凝滴度观察银翘散和玉屏风颗粒以及联合应用二者不同时间点体外直接抑制流感病毒及对流感病毒感染鸡胚的治疗作用。结果:银翘散提取物、玉屏风颗粒对IV感染鸡胚具有治疗保护作用。银翘散提取物、玉屏风颗粒联合应用比单方对IV感染鸡胚保护作用略强,但无显著差异。结论:银翘散提取物、玉屏风颗粒以及联合应用二者具有治疗流感病毒作用。

Objective：To observe and compare the therapeutic effects of the main constituents of YinqiaoPowder and Yupingfeng Granule or combination both on infected chick embryo. Methods：Cultivation in the chick embryo and hem-agglutination test are applied to observe the extractives o f the main constituents o f Yinqiao Powder and Yupingfeng Granule or combination both inhibit IV in vitro at different times and the prevent and therapeutic effects on the infected chick embryo. Results：The main constituents of YinqiaoPowder and Yupingfeng Granule have the protect and therapeutic effects on the infected chick embryo.Combination both have stronger therapeutic effect,but have no significant difference. Conclusion：YinqiaoPowder and Yupingfeng Granule or combination both have the therapeutic effect on influenza.
