| 摘 要： | 背景:研究表明Wistar和SD大鼠普遍为封闭杂交系而非近交系,有一定的遗传稳定性,同时也有一定的基因多态性,因此Wistar和SD大鼠之间的肝移植模型可能不是研究大鼠急性排斥反应的理想模型.目的:建立Lewis-BN大鼠肝脏移植急性排斥反应模型.方法:采用改良的"Kamada"二袖套法,分别进行同基因Lewis-Lewis间肝移植及Lewis-BN间肝移植.移植后3,5,7 d观察受体肝脏组织病理变化,测定谷丙转氨酶和总胆红素水平变化及大鼠存活时间.结果与结论:同基因移植组大鼠无急性排斥表现,平均存活时间超过100 d,肝功能损害较轻.异基因移植组大鼠存活 (12.75±1.25) d,移植后第7 天肝脏病理检查有明显的排斥反应,肝功能损害较重,移植后各时相点谷丙转氨酶和总胆红素水平均明显高于同基因移植组(P < 0.05).提示Lewis-BN大鼠肝移植组合为稳定的大鼠肝移植急性排斥模型,但近交系大鼠对手术耐受性差,建模难度大,熟练的显微外科技术和细心轻柔的操作是模型成功的关键.

| Abstract: | BACKGROUND:Some research indicates that the Wistar and Sprague Dawley rats belong to closed colony strains,rather than inbred strains,which not only has some hereditary stability but also genetic polymorphism. Thus,the Wistar to SD rat liver transplantation models may not be the ideal models to study the acute rejection of rat liver transplantation. OBJECTIVE:To establish an acute rejection model of Lewis-BN rat orthotopic liver transplantation. METHODS:The model was established by modified Kamada's two-cuf... |
