摘要: 目的 研究注射用尼莫地平脂质体(NDLI) 对大鼠全脑缺血再灌注和小鼠缺氧性损伤的保护作用。方法 采用小鼠常压耐缺氧实验和小鼠断头实验, 观察NDLI 对小鼠耐缺氧能力的影响;采用Pulsinelli 四动脉结扎法略加改良制作全脑缺血模型, 记录对脑电图(EEG) 及翻正反射的恢复时间、脑组织匀浆伊文思蓝含量的影响。结果 NDLI 能显著延长小鼠的存活时间及断头后喘气持续时间, 缩短大鼠脑电图及翻正反射的恢复时间, 降低脑匀浆伊文思蓝的含量。结论 NDLI 对全脑缺血再灌注和缺氧性损伤有明显的保护作用。

Abstract: AIM: To study the protective effects of nimodipine liposomes for injection (NDLI) on injuries of total cerebral ischemia/reperfusion(I/R) in rats and anoxia in mice.METHODS: Acute anoxia in mice was produced by hypoxia under normal pressure and decapitation.In these two models the survival time and persistent time of gasping were observed.Ameliorated pulsinelli four-vessel occlusion method was used to make global brain ischemia model.The EEG, the time of righting reflex recovery and Evans blue content in the homogenate of the brain tissues were recorded.RESULTS: NDLI obviously prolonged the survival time and persistent time of gasping in mice subjected to acute anoxia, remarkably shortened the time of EEG recovery and righting reflex recovery, and reduced Evens blue content in the homogenate.CONCLUSION: NDLI has significantly protective effects on injuries of total cerebral I/R and anoxia.

Key words: nimodipine liposomes for injection, four-vessel occlusion, cerebral ischemia/reperfusion, cerebral anoxia, Evans blue
