摘要: 目的 探讨丹参对单纯疱疹病毒I型(HerpesSimpleVirus-1,HSV-Ⅰ)感染所致的小鼠病毒性脑炎的疗效及机理。方法 建立HSV-Ⅰ感染所致的病毒性脑损伤模型,观察小鼠的死亡率,检测小鼠血液中的细胞因子白介素-1β(IL-1β)、γ-干扰素(IFN-γ)、一氧化氮(NO)水平变化,以及电镜下小鼠神经细胞形态结构的变化。结果 电镜下HSV-I感染后小鼠脑细胞胞浆水肿明显,核仁固缩,核内结构破坏,多数线粒体呈空泡样改变,脊突破坏,髓鞘严重松解,核仁内可见病毒颗粒;IL-1β、IFN-γ、NO水平及小鼠的死亡率均明显上升。丹参治疗后小鼠脑组织病理改变减轻,死亡数及IL-1β、NO水平明显下降,而IFN-γ继续上升。结论 丹参早期应用对病毒性脑损伤有一定的疗效,对病毒性脑炎的临床用药有指导意义。其治疗病毒性脑损伤的作用机制可能是通过调节免疫应答,影响IL-1β、IFN-γ和NO等细胞因子的水平减轻炎症反应,改善脑损伤。

Abstract: AIM: To explore the curative effect and mechanism of Salvia miltiorrhiza Bunge (SMB) against mice' s viral encephalitis induced by simple herpes virus-1(HSV-1).METHODS: To establish damage model of viral encephalitis in order to observe the mortality rate of mouse,to test the level change of the factors of cells such as IL-1β,IFN-γ,NO and to observe the structural change in neural cells under the electron microscope.RESULTS: Cells swelled,nucleoli pyknosised and the structure of nucleus was damaged after been inoculated with HSV-1 under the electron microscope.There was hollow-like change in mitochondria and virus-like pellet in nucleus,spine was damaged,the levels of IL-1β,IFN-γ,NO and the death rate obviously increased in model group,and those indexes decreased after treating with SMB except IFN-γ.CONCLUSION: Early treated with SMB has certain clinical curative effect.It may result from regulating immune response in the body.
