中西医结合治疗小鼠柯萨奇B3病毒性心肌炎的实验研究

目的；观察中西医结合治疗小鼠柯萨奇Ｂ３（ＣＶＢ３）病毒性心肌炎（ＶＭＣ）的疗效。方法：腹腔接种ＣＶＢ３病毒液以建立ＶＭＣ模型。随机分为对照、黄芪、牛磺酸和辅助产Ｑ１０（ＣｏＱ１０）单独用药组及黄芪分别加牛磺酸、ＣｏＱ１０治疗组以及三药联合治疗组。观察了７组在死亡率、心电图、心肌中ＣＶＢ３ＲＮＡ含量及心肌形态学改变差别。结果：黄芪联合牛磺酸和ＣｏＱ１０治疗可明显降低小鼠的死亡经及急性期异常心电图的必

Experimental Study on Treatment of Viral Myocarditis in Mice by Integrated Traditional Chinese and Western Medicine

OBJECTIVE: To clarify the effects of Astragalus Membranaceus (AM) combined with taurine and/or coenzyme Q10(CoQ10) on coxsackievirus B3 (CVB3) murine myocarditis. METHODS: Viral myocarditis model was created by intraperitoneal inoculation with CVB3 solution and were treated by saline, AM, taurine, CoQ10, AM + taurine, AM + CoQ10, AM + taurine + CoQ10, respectively. The mortality, ECG, CVB3-RNA in myocardium and myocardial histopathologic changes were observed. RESULTS: AM combined with taurine and CoQ10 could significantly reduce the mortality of the mice and the incidence of abnormal ECG at acute stage. CVB3-RNA was significantly reduced in AM treated group, especially in AM + taurine group. No anti-virus effect was found in CoQ10 group. All drugs could lighten myocardial histopathologic changes and the effect could be enhanced by combined treatment. CONCLUSIONS: AM, taurine and CoQ10 have some curative effects on CVB3 murine myocarditis, AM combined with taurine and CoQ10 is the best.
