Abstract:
Objective:To study the effect of Cyclosporine A preconditioning on liver preservation and transplantation in rat.Methods:Rats were divided randomly into control group (group A,HTK solution preservation) and CsA precondioning group (groupB,HTK solution preservation+1?M CsA).The livers of two groups were had been all preservated for 12 hours before operation of orthotopic liver transplantation.The content of serum AST,ALT,LDH were all assayed during preservation in 0h,12h and 7d post liver transplantation,as well as determination of mitochondrial respiration function parameters (RCR and P/O).The change of cell morphology and apoptosis were also observed by TUNEL stain,and miclroscopes in two groups.Results:The content of serum ALT,AST and LDH in group B were less than in group A after presenvation for 12 hours.RCR and P/O parameters of mitochondrial respiration in group B on preservation for 12h.and for 30 min after operation were more than in group A.Cell morphology and apoptosis changed slingtly compared with group B.Conclusion:CsA preconditioning can relieve injury of donated liver during cold preseration and reperfusion.It protects mitochondrial fuction of liver cells and inlibits cell apoptosisa.
