AIM: To compare Institut Georges Lopez(IGL-1) and Celsior preservation solutions for hepatic endothelium relaxation and liver cold ischemia reperfusion injury(IRI).METHODS: Two experimental models were used.In the first one, acetylcholine-induced endotheliumdependent relaxation(EDR) was measured in isolated ring preparations of rat hepatic arteries preserved or not in IGL-1 or Celsior solutions(24 h at 4 ℃).To determine nitric oxide(NO) and cyclooxygenase EDR, hepatic arteries were incubated with L-NG-nitroarginine methyl ester(L-NAME), an inhibitor of endothelium nitric oxide synthase(e NOS), or with L-NAME plus indomethacin, an inhibitor of cyclooxygenase.In the second experiment, rat livers were cold-stored in IGL-1 or Celsior solutions for 24 h at 4 ℃ and then perfused "ex vivo " for 2 h at 37 ℃.Liver injury was assessed by transaminase measurements, liver function by bile production and bromosulfophthalein clearance, oxidative stress by malondialdehyde levels and catalase activity and alterations in cell signaling pathways by pA kt, pA MPK, eN OS and MAPKs proteins level.RESULTS: After cold storage for 24 h with either Celsior or IGL-1, EDR was only slightly altered.Infreshly isolated arteries, EDR was exclusively mediated by NO.However, cold-stored arteries showed NOand COX-dependent relaxation.The decrease in NO-dependent relaxation after cold storage was significantly more marked with Celsior.The second study indicated that IGL-1 solution obtained better liver preservation and protection against IRI than Celsior.Liver injury was reduced, function was improved and there was less oxidative stress.IGL-1 solution activated Akt and AMPK, which was concomitant with increased eN OS expression and nitrite/nitrate levels.Furthermore, MAPKs kinases were regulated in livers preserved with IGL-1 solution since reductions in p-p38, p-ERK and p-JNK protein levels were observed.CONCLUSION: IGL-1 solution preserved NO-dependent relaxation better than Celsior storage solution and enhanced liver graft preservation.
