三七总黄酮对病毒性心肌炎模型治疗作用的药效学研究

目的评价三七总黄酮对柯萨奇B3病毒感染体外、体内模型的治疗作用。方法采用柯萨奇B3型病毒感染原代培养Wistar乳鼠心肌细胞方法,建立体外病毒感染模型;Balb/c小鼠腹腔注射柯萨奇B3型病毒感染建立病毒性心肌炎体内实验动物模型。结果三七总黄酮能明显抑制体外培养心肌细胞病变;治疗组小鼠生存率明显增加,心肌酶释放活性明显降低;小鼠干扰素水平上升,病毒滴度降低;炎性浸润作用明显减轻。结论三七总黄酮对柯萨奇B3病毒所致小鼠病毒性心肌炎具有一定治疗作用。

Study about pharmacodynamics of radix notoginseng flavones on viral myocarditic models

Aim To observe the antiviral function of Radix Notoginseng flavone on a virus infection model caused by COXB3 virus in vitro To establish an experimental and in vivo. Methods in vitro model of viral myocarditics based on primary culture of myocardial cells of newborn Wistar rats and a Balb/c mouse model of viral myocarditics through intraperitoneal injection. Results In vitro Radix Notoginseng flavone obviously inhibited pathologic change of cultured cardiac cells; it reduced release of enzymes from myocardial cells, and increased the level of interferon in mouse spleen, and inhibited inflammatory cells infiltration among cardiac cells in Balb/c mice infected by COXB3 virus; survival rate of mice in treated groups increased. Conclusion Radix Notoginseng flavonoe has therapeutic efficacy on viral myocarditis caused by COXB3 virus.
