摘要
目的:探讨冻存猪肝细胞移植治疗大白鼠急性肝衰的可行性。方法:将猪肝细胞在液氮中冻存150d后移植给切除80%肝叶的大鼠。结果:冻存肝细胞活率为冻前的78%,光、电镜显示细胞完整,细胞内糖原和葡萄糖-6-磷酸酶丰富。移植组鼠的存活率为16/l7,明显高于对照组3/9,P=0.002。但肝衰后2和7d的两组间残肝重量及肝功能生化值并无显著差异。结论:冻存猪肝细胞移植可治疗急性肝衰,其作用机理可能是综合效应的结果。
Objective:The experiment aimed at studying the possibility of transplantation of pig' s cryop-reservated hepatocytes treating acute hepatic failure in Wistar ratx.Methods:Porcine hepatocytes werecryopreserved in liquid nitrogen for 150 days,which were transplanted into the rats in which 80% of liver lobes were resected later.Results:The viability of the cryopreserved cells was 78% of the freshcells.Morphologically intact hepatocytes were observed under light and electron microscopy.Glycogenand glucose-6-phosphatase within the cells were rich.Survival rate of rats in transplant group was 16/17,significantly higher than 3/9 of control group(P=0.0020)But there weren't significant differ-ences in the weights of remaining partx of livers and biochemical values of hepatic function between the 2-day group and 7-day group after liver failure.Conclusions:The transplant of pig's frozen hepatocytescould treat the acute hepatic failure and its mechanixm seemed to be a result of multiple effects.
