Abstract： 目的研究粒细胞集落刺激因子对新西兰白兔心肌梗死区域的修复作用.方法 30只新西兰白兔随机分为假手术组、心肌梗死组及药物治疗组.药物治疗组心肌梗死模型制作采用开胸左冠脉边缘支结扎法,术前24 h及术后6 d予G-CSF 10 μg/(kg*d)皮下注射处理.另外两组皮下注射等量的生理盐水1周对照.三组术前、术后4周均查心超,观察心功能的改变.4周时处死动物,取出心脏,HE和免疫组化染色观察心肌梗死区域的病理变化.结果药物治疗组4周后心功能EF值(0.695±0.038)较心肌梗死组(0.554±0.065)上升(P＜0.05),低于假手术组(0.747±0.019);HE染色和免疫组化病理检查发现有新生的血管.结论粒细胞集落刺激因子可修复心肌梗死区域,促进血管新生,改善心功能.
