大鼠异位辅助性肝移植肝的形态及功能变化

目的 :观察大鼠异位辅助性肝移植后的自体肝及辅助肝 (两肝 )的形态及功能改变。　方法 :建立大鼠异位辅助性肝移植模型 ,行 (血流动力学 )核素显像、电镜观察及光镜检测 ,评价术后大鼠生存以及移植肝功能状况。　结果 :大鼠异位辅助性肝移植模型切实可行 ,手术成功率较高 (93.3% )。术后 1周存活率达 80 % ,并能长期存活(>3个月 )。术后行相关检查 ,表明供肝随移植时间延长逐渐萎缩 ,功能逐渐丧失 ,4 5天后已基本无功能。　结论 :异位辅助性肝移植中 ,两肝共存时 ,自体肝的功能基本不受影响 ,随着移植时间延长 ,辅助肝逐渐萎缩。

Morphological diversification in heterotopic auxiliary liver transplantation in rats

Objective:In order to study the morphological diversification in heterotopic liver auxiliary transplantation(HLAT). Methods:HLAT model in rats was established, the status of rats survival and graft function was evaluated postoperatively by rheometer, SPECT electrical microscope etc. Results:Rat HLAT model was feasible, the operative success rate was 93.3%, one week postoperative survival rate was 80%,the survival time without complications was more than 3 months. The function of the native liver was not affected, as the time goes by, the graft become atrophic after 45 days postoperatively. Conclusion:In HLAT model, the function of the native liver was not affected, 45-days-after the transplantation, the graft become atrophic.
