Abstract´╝Ü 目的:探讨银杏叶提取物(EGb761)对慢性乙型肝炎患者肝窦微循环障碍的影响.方法:将47例慢性乙型肝炎患者分为EGb761治疗组26例及对照组21例,治疗前后分别进行肝组织活检术,肝组织行HE染色,并各取10例电镜观察治疗前后的肝窦微循环变化.结果:治疗后肝活检证实,与治疗前(炎症计分:15.7±6.3;纤维化计分:11.9±6.2)和对照组治疗后(炎症计分:14.24±6.6;纤维化计分:11.5±5.6)相比,EGb761治疗组肝组织损伤程度及纤维化程度明显改善(炎症计分:10.7±4.8;纤维化计分:8.3±4.2)(P<0.05);与治疗前相比,EGb761治疗组电镜下肝窦内血细胞聚集或微血栓形成(32 vs 56,P<0.01)、窦腔及Disse隙胶原沉积(23 vs 38,P0.05)、窦内皮损伤(41 vs 59,P<0.05)、毛细血管化(17 vs 32,P<0.05)等肝脏微循环障碍明显改善;而对照组治疗前后均无明显变化(P0.05).结论:银杏叶提取物能保护慢性乙肝患者肝窦内皮细胞,抑制肝窦内血细胞聚集及微血栓形成,抑制肝窦及Disse隙内胶原沉积及肝窦毛细血管化,改善肝脏微循环.
