【摘要】 目的:研究秋梨润肺浸膏对小鼠免疫功能的影响及对流感病毒鼠肺适应株(FM1)的体内防治作用。方法:小鼠舌下给予秋梨润肺浸膏,检测其体重、脾重及T、B细胞刺激指数等免疫指标;建立小鼠、鸡胚的流感病毒感染模型,观察药物对流感病毒增殖的抑制作用。结果:秋梨润肺浸膏使小鼠体重、脾指数及T、B细胞刺激指数增加;并有效阻止流感病毒对鸡胚的感染,降低了小鼠的死亡率。结论:秋梨润肺浸膏能增强小鼠免疫功能并具有一定的抗流感病毒作用。更多还原

【Abstract】 Objective:To investigate the effect of Qiulirunfei extracta on immunological function and Influenza virus type A(FM1 strain) in ICR mice.Methods:After given Qiulirunfei extracta,mice’s body weight,spleen weight and lymphocyte stimulation index(SI)were tested;its antiviral effect was also observed in mice and chick embryo.Results:Qiulirunfei extracta inhibited effectively the growth of influenza virus type A(FM1 strain) in chick embryo,and reduced the mortality rate of mice infected by influenza virus type A(FM1 strain).Compared with control group,body weight,spleen index in experiment group increased greatly,and SI of lymphocyte increased significantly too.Conclusion:Qiulirunfei extracta shows antiviral effects,and it is a good immune system enhancer.更多还原
