摘要 目的 模拟临床上治疗股骨头坏死的开窗法的手术过程制备兔股骨头缺损 ,并植入bFGF/PDPB (碱性成纤维细胞生长因子 +部分脱蛋白骨 ) ,以探讨bFGF对股骨头缺损的再血管化作用。方法 成年健康新西兰白兔 2 4只 ,切开关节囊 ,在头颈交界处开窗 ,建立缺损模型。 48侧股骨头随机分为 3组 ;A组植入bFGF/PDPB ;B组植入PDPB ;C组为空白对照。术后 2周、 4周、 8周处死动物 ,制备墨汁灌注标本 ,样本行病理学观察 ,图像分析。结果 病理学观察及图像分析结果表明 :A组在术后 2周、 4周和 8周股骨头缺损区修复组织血管生成明显优于B组 ,A ,B两组优于C组。结论 bFGF具有促进股骨头缺损的再血管化作用 。
