Effect of the Prescription of Yiqiyangyin Huoxuehuayu on the Level of Serum ?-IFN in Mice Model with Viral Dilated Cardiomyopathy / 中国中医药信息杂志

ABSTRACT

Objective To investigate the effect of the prescription of Yiqiyangyin Huoxuehuayu on the mice model with viral dilated cardiomyopathy by examining the levels of serum ?-IFN.Methods Replicated the animal models of early viral dilated cardiomyopathy by injecting the CVB3m virus to the peritoneal cavity of the Balb/c mice.Two hundred and ten Balb/c mice were divided into 4 groups at randomblank group,model group,high and low dose traditional Chinese medicine group.The blank group has 30 mice.The other three group has 60 mice each.The mice of high dose traditional Chinese medicine group and low dose traditional Chinese medicine group were treated with the prescription of Yiqiyangyin Huoxuehuayu.The change of pathomorphology in the cardiac muscle tissue,the rate of death,the weight change and the cardiac weight index were observed after 4 weeks of the treatment.At the same time,ELISA method was used to exam the levels of serum ?-IFN.Results The prescription of Yiqiyangyin Huoxuehuayu can induce the expression of serum ?-IFN in the mice with viral dilated cardiomyopathy.The mean level of serum ?-IFN of the high dose traditional Chinese medicine group and low dose traditional Chinese medicine group were significantly higher than that of the model group.Conclusions The prescription of Yiqiyangyin Huoxuehuayu can inhibit the viral replication and regulate the immunologic function.
