Improved method of orthotopic liver transplantation model in mice / 解放军医学杂志

ABSTRACT

Objective To improve the method of orthotopic liver transplantation model in mice.Methods On the basis of "Qian SG" mothod,the techniques of perfusion,harvesting,and trimming of donor's liver,as well as the anastomosis of superior and inferior caval veins were improved.Operations were performed in 70 mice with improved technique(experiment group) and in 70 mice with conventional technique(control group),respectively.The operation time in both donors and recipients,and the survival rates of 48h,1 week and 1 month after operation were compared between the two groups.Results The operation time for both donors and recipients and the time of anhepatic phase were 37?2min,45?2min and 16?2min,respectively in experiment group,while they were 45?2min,54?2min and 23?2min,respectively,in control group,so that the average time for each procedure was significantly shorter(P0.05).Conclusions The improved technique may shorten the operation time and raise the survival rate,and is an ideal method for the establishment of orthotopic liver transplantation model in mice.
