| 摘 要： | 目的研究西洛他唑对大鼠脑微血管内皮细胞缺血再灌注损伤的保护作用机制。方法以原代方法培养大鼠脑微血管内皮细胞并传代,将第3代传代细胞随机分为正常对照组、西洛他唑组、溶剂对照组和缺血再灌注模型组(再灌模型组)4组,对后3组大鼠建立脑微血管内皮细胞糖氧剥夺后复糖氧模型,模拟缺血再灌注过程,并对西洛他唑组和溶剂对照组在造模同时分别以终浓度1×10-5mmol/L西洛他唑〔二甲基亚砜(DMSO)为溶剂〕和0.05%(体积分数)DMSO进行干预。糖氧剥夺3 h复糖氧24 h后,测定各组细胞上清液中诱导型一氧化氮合酶(iNOS)和内皮型一氧化氮合酶(eNOS)水平及细胞内环磷腺苷酸(cAMP)水平,并以四唑盐(MTT)比色实验测定细胞活力。结果西洛他唑组与再灌模型组比较,eNOS水平明显提高,iNOS水平明显降低,cAMP水平及细胞存活率显著提高(均P<0.05)。结论西洛他唑对大鼠脑微血管内皮细胞的缺血再灌注损伤有保护作用,其作用机制可能与促进eNOS水平升高和iNOS水平降低有关。

| Abstract: | Objective To study the protective mechanisms of cilostazol on cerebral microvascular endothelial cells in ischemia reperfusion models in vitro.Methods Cerebral microvascular endothelial cells of the Wistar rats were cultured and subcultured in vitro.All the 3rd generation cells were divided randomly into the normal group,the cilostazol treatment group,the solvent group and the ischemia-reperfusion injury(IRI) group.The cell model of ischemia reperfusion was established by regaining oxygen-glucose after oxyg... |
