摘要

啮齿类动物是构建动物模型时最常使用的实验工具,然而目前并没有啮齿类动物胆道系统结构的详细报道。本文
通过静脉注射吲哚菁绿溶液,并同时结扎胆总管,数分钟后可使小鼠(Mus musculus)肝外胆道系统呈翠绿色,可见各肝
叶胆管常于近胆囊处汇入胆总管。吲哚菁绿肝外胆管造影后,利用 25 × 显微镜观察小鼠左外叶肝脏脉管系统,将小鼠左
外叶肝脏分为隐藏型、显露差型、显露一般型和显露完全型。选择显露一般型和显露完全型,用 10-0 带线缝合针于左外
叶脏面,包绕左外叶门静脉进针和出针,外科结结扎。手术后 3 天观察,左外叶肝脏鲜活,未结扎叶肝脏 Ki67 阳性细胞核
占比提高,肝叶重量明显增加,成功诱导了肝脏再生。
