目的 探讨疏风解毒胶囊对病毒性心肌炎(VMC)小鼠心肌组织形态和血清肿瘤坏死因子-α(TNF-α)、淀粉样蛋白A(SAA)水平的影响。方法 Balb/c小鼠随机分为对照组,模型组,疏风解毒胶囊0.1、0.2、0.5 g/kg组和利巴韦林0.1 g/kg组,除对照组外ip柯萨奇病毒B3(CVB3)建立VMC模型,造模2 h后给药,连续给药7 d,第4、8天各处死一半小鼠,取心肌组织HE染色观察病理变化,眼眶取血测定血清TNF-α、SAA水平。结果 与对照组比较,模型组出现心肌炎症及坏死,血清TNF-α、SAA水平明显升高(P<0.05);疏风解毒胶囊0.2、0.5 g/kg组与模型组比较,心肌组织病理变化明显减轻;血清TNF-α、SAA水平明显降低(P<0.05)。结论 疏风解毒胶囊缓解VMC小鼠心肌病理形态损伤、抑制炎症,发挥明显的抗病毒作用。

Objective To investigate the effect of Shufengjiedu Capsule on the modality of myocardial tissue and levels of serum TNF-α and SAA in mice with viral myocarditis. Methods BALB/C mice were randomly divided into normal control group, virus group, Shufengjiedu Capsule 0.1, 0.2, 0.5 g/kg/d groups, and ribavirin 0.1 g/kg/d group. The mouse model of viral myocarditis was established by ip injection of CVB3, and after 2 h of modeling, the animals were continuously admistered for 7 d. Half of the mice were killed on days 4 and 8, the myocardium tissue was HE stained to observe the pathological changes and blood samples were taken for measurement of serum TNF-α and SAA contents. Results Compared with the control group, the pathological changes of myocardium were significantly decreased in high-dose Shufengjiedu Capsule group, and the serum TNF-α and SAA contents were significantly decreased(P<0.05). Conclusion Shufengjiedu Capsule has antiviral effect and could alleviate the inflammation on mice with viral myocarditis.
