| 摘 要： | 目的探讨大剂量甲基强的松龙对蛛网膜下腔出血(SAH)后脑血管痉挛(CVS)的作用。方法将24只雄性新西兰白兔随机分成2组:SAH对照组和SAH 大剂量甲基强的松龙(MP,18mg/kg)治疗组。通过枕大池二次注血法构建SAH模型,观察MP对脑基底动脉的影响。应用酶联免疫生化技术检测各组兔基底动脉血管平滑肌细胞膜蛋白激酶C(PKC)活性。结果经脑血管造影证实该剂量甲基强的松龙明显减轻实验性脑血管痉挛的严重程度,与对照组相比,PKC活性在大剂量甲基强的松龙治疗组没有明显提高。结论大剂量甲基强的松龙能够明显减轻脑血管痉挛程度,通过抑制血管平滑肌细胞来防治脑血管痉挛的发生发展。

| Abstract: | Objective To explore the effect of methylprednisolone(MP)on delayed cerebral vasospasm(CVS)after subarachnoid hemorrhage(SAH).Methods Twenty-four male rabbits were randomly divided into two groups:non-treated group and high-dose MP treated group.We used methylprednisolone to treat the cerebral vasospasm after SAH,which was induced by single cistern injection of auto genous arterial blood in rabbits.Results The MP significantly reduced angiographic severity of vasospasm.In the treated group,PKC activity of the artery was not enhanced compared with non-treated group at any time.Conclusion The result suggests that MP could prevent vasospasm through inhibition of PKC activity. |
