ABSTRACT

Objective To explore the effect of reduced glutathione and venous systemic oxygen perfusion on apoptosis and ultrastructure of hepatocytes in rat steatotic liver grafts. Methods Before liver transplantation grade Ⅱ steatotic liver model was established by a diet consisting of 79% standard diet,20% lard and 1% cholesterol for 6 weeks. In pretreatment group, the donor received intraperitoneal injection of reduced glutathione at a dosage of 500 mg/kg/body weight 3 times a day for 2 days, and intrahepatic venous oxygen perfusion for 6 hours while kept in cold preservation. Results Preconditioning measures in steatotic liver grafts significantly decreased the hepatocytes necrosis (38?10)% vs (17?6)%, P
