【Abstract】ObjectiveTo compare the effects of self-designed KYL solution on rat liver preservation with UW solution.
Methods Using non-circulated isolated perfused rat liver,SD rat livers were randomly preserved for 0、4、8、16、24 and 48 hours with self-designed KYL solution or UW solution. The effects were assessed by measuring the bile production, the contents of AST， ALT，LDH，free radical（ MDA） and SOD in KrebsHenseleit’s perfusate and the content of intracellar calaium of the rat hepatocytes, and by observing the morphological changes in liver. At the same time, the normal saline was used to preserve the rats liver as negative comparison to know if KYL solution and UW solution can prevent the ischemiareperfusion injury in rat liver transplantation.
Results At different periods within 16 hours of preservation,the bile production of the rat livers which were preserved by KYL solution were more than those were preserved by UW solution （P＜0.01）, JP2The contents of AST， ALT and LDH in Krebs-Henseleit’s perfusate were near in UW solution’s. The content of intracellar calaium of the rat hepatocytes which were preserved by KYL solution were less than those were preserved by UW solution （P＜0.01）. In KYL group, the content of MDA was lower than that UW group, the content of SOD was higher than that UW group at 24 and 48 h(P＜0.01). Morphological changes in both groups were almost same. All variables of both groups were better than the rat livers preserved by the normal saline. It was proved that both KYL solution and UW solution could protect the rat livers.
Conclusion The study indicated that the effects of self-designed KYL solution on rat liver preservation are similar to that of UW solution. The bile production after reperfusion and the content of intracellar calaium of the rat hepatocytes in KYL group are better than those in UW group .The effect of prevention of rat hepatocellular oedema by self-designed KYL solution are worse than that of UW solution.
