| 摘 要： | 目的探讨早期应用银杏叶提取物(EGB)对大鼠颅脑损伤后脑血管内皮细胞的保护和调节作用。方法将140只大鼠按随机数字表法随机分为对照组和EGB治疗组,按Marmarous等人的方法建立弥漫性脑损伤模型,EGB治疗组在伤后即刻腹腔注射EGB,以后每24h腹腔注射一次直至被处死,对照组注射等量生理盐水。分别在伤后1h、4h、8h、12h、24h、3d、7d七个时间点断头取脑组织,采用免疫组化和荧光定量PCR测定大脑皮层脑血管内皮细胞不同时间点血栓调节蛋白(TM)和假性血管性血友病因子(vWF)蛋白表达水平,并观察大鼠皮层血管变化及皮层病理学变化。结果伤后4h至伤后3dEGB治疗组脑组织中TM和vWF的表达水平与对照组相比明显下降(P0.05)。结论EGB可以抑制大鼠弥漫性颅脑损伤后脑血管内皮细胞活化标志物TM和vWF的表达,其机制可能与EGB抑制脑血管内皮细胞的活化有关。
