Abstract:
Objective To compare the protecting effect of hypoxia preconditioning(HP) and deferoxam-ine preconditioning (DP)on transplanted livers and to search a protecting method which is suitable for clini-cal practice.Methods SD rats are randomly divided into four groups:sham operation group (S),analogic transplantation group (AT),deferoxamine preconditioning group (DP) and hypoxia preconditioning group (HP).Twenty-four hours after operation,several factors of each group were measured respectively,inclu-ding deterioration of histomorphology,hepatic zymogram in the serum,hypoxia inducing factor-1 (HIF-1α)and malonaldehyde (MDA) in hepatic tissue.Results The levels of alanine aminotransferase (ALT),glu-tamic oxalacetic transaminase (AST) and alkaline phosphatase (ALP) in AT group,DP group and HP group were higher than S group's.Levels of ALT,AST,ALP in AT group were dramatically high,hepatic tissue suffers from edema,degeneration even necrosis.By contrast,the pathological change is milder in DP group and HP group.HIF-1α in hepatic tissue of AT group was lower than that in DP group and HP group,MDA was higher than two latters (P < 0.05).Conclusion DP can protect transplanted liver as same as HP,however,DP is more suitable for clinical practice.
