SX-1液对肝脏保存效果的实验研究

目的 应用改良后的Kamada二袖套法大鼠原位肝移植模型,检验SX-1液、HC-A液和UW液对肝脏保存的效果.方法 在无菌条件下配制肝脏保存液.建立大鼠原位肝移植模型.使用SX-1液、UW液和HC-A液保存大鼠肝脏2、8、24 h后行大鼠原位肝移植,于移植后6 h比较各项肝脏功能.结果 对于ALT、AST,SX-1液组(2、8、24 h)与UW液组同步升高,分析无统计学意义(P＞0.05),与HC-A液组相比,差异有统计学意义(P＜0.05).对于LDH,SX-1液组(2 h、8 h、24 h)与HC-A液组同步升高,差异无统计学意义(P＞0.05),与UW液组相比,差异有统计学意义(P＜0.05).对于分泌胆汁的肝脏个数,各组别与分泌胆汁的肝脏个数无差别(P＞0.05).本组内各时间点分泌胆汁个数有差别(P＜0.05).随肝脏保存时间增长,分泌胆汁的肝脏个数减少.结论 经大鼠原位肝移植模型证实,SX-1液在肝脏酶学方面与UW液作用相当,超过HC-A液水平.肝移植后6 h肝脏分泌胆汁的个数方面,SX-1液与HC-A液、UW液间无明显差别.

Effect of liver preservation in SX-1 solution in rats

Objective To compare the efficacy of liver preservation in SX-1 solution,HC-A solution and UW solution in the two-cuff technique orthotopic liver transplantation model in rats.Methods We confected SX-1 solution using of aseptic technique and built up two-cuff technique orthotopie liver transplantation model in rats.The SX-1 solution,UW solution and HC-A solution preserved rats livers in 2 h,8 h and 24 h,then went orthotopic liver transplantation.The various hepatic indices were determined when the rats survived for 6 hours after the operation.Results For the ALT,AST,the SX-1 solution group(2 h,8 h,24 h)and UW solution group went up synchronously,there was no statistical significance,(P＞0.05).Compared with HC-A solution group the SX-1 solution group (2 h,8 h,24 h)has already shown the statistical signifcance(P＜0.05).For the LDH,the SX-1 solution group (2 h,8 h,24 h)and HC-A solution group went up synchronously,there was no statistical significance(P＞0.05).Compared with UW solution group the SX-1 solution group(2 h,8 h,24 h)has already shown the statistical significance(P＜0.05).For the number of liver with bile production,each group didn1 show the statistical significance (P＜0.05).The time of preserving liver increased with the number of liver with bile production reducing.Conclusions Confirmed by the orthotopie liver transplantation model in rat,the SX-1 solution is the same as the UW solution in the indices of hepatic enzymologists.exceeding the HC-A solution.The SX-1 solution is the same as HC-A solution and UW solution in the number of liver with bile production.
