摘要: 目的: 研究果糖二磷酸钠镁(FDPM)对大鼠脑缺血再灌注引起脑损伤的保护作用。方法: 自大鼠颈总动脉插入尼龙线栓栓塞大脑中动脉, 造成大脑缺血, 拔出线栓实现再灌注。脑缺血10min后给予400mg·kg-1 FDPM , 400mg·kg-1 FDP30mg·kg-1 MgSO4, 分别于脑缺血1h再灌注2h , 5h2.3h分别进行神经病学评分, 并于脑缺血1h再灌注2 3h时测定脑梗塞面积及脑组织MDA含量, 观察大脑组织病理学变化。结果: FDPM降低脑血再灌注大鼠神经病学评分, 缩小脑梗塞面积, 降低脑组织MDA含量, 减轻光镜下脑组织的病理改变, 其作用强于FDPMgSO4结论: FDPM可显著保护大脑缺血再灌注引起的脑损伤, 其作用优于单用FDPMgSO4

Abstract: Objective: To study the effects of sodium magnesiusm fructose diphosphate (FDPM) on brain damage of rats after ischemia-reperfusion. Methods: Rats were subjected to cerebral ischemia-reperfusion induced by inserting a nylon thread into internal carotid artery to block the origin of middle cerebral artery and removing the thread later. FDPM (400 mg·kg-1), fructose-1,6-diphosphate (FDP, 400 mg·kg-1)and magnesium sulfate (MgSO4, 30 mg·kg-1) were administrated 10 min after the onset of ischemia. Neurological scale, brain infarct area, Malondialdehyde (MDA) content and histopathological changes of brain tissue were studied. Results: FDPM decreased neurological scale, diminished brain infarct area, reduced MDA content and relieved histopathological change of rat brain tissue subjected to ischemia-reperfusion. These effects were more powerful than that of FDP or MgSO4. Conclusions: It is suggested that FDPM markedly prevented rats against brain damage after cerebral ischemia-reperfusion, and its effect was better than that of FDP or MgSO4.
