摘要
目的:探讨冬虫夏草醇提取物对急性病毒性心肌炎的干预作用。方法:采用柯萨奇B组3型病毒复制病毒性心肌炎小鼠模型,免疫组化染色观察心肌iNOS表达,同时观察光镜下心肌组织学变化。结果:与模型组比较,虫草醇提取物干预组心肌炎症坏死半定量分析显著减轻,心肌iNOS面密度值均显著升高。结论:虫草醇提取物对急性病毒性心肌炎有明显保护作用,其保护机制与诱导心肌iNOS表达,增加NO产生等有关。
Objective: To investigated the effect of cordyceps sinensis alcohol extraction (CASE) on acute viral myocarditis (VMC). Methods: Acute VMC model was made in mice with Coxsackievirus B3(CVB3)intraperitoneal inoculation. iNOS in heart was examined immuno-chemically. Histological changes were determined microscopically. Results: Myocardial necrosis semi quantity score were significantly lower(P<0.01)for CASE intervention group, and iNOS density in heart were significantly higher(P<0.01). Conclusions: CSAE has significant protection on acute VMC, and its possible mechanisms include induction of expression of iNOS in heart and increase of NO production.
