The aim of this study was to investigate the effect of carnosine (CAR) alone and together with vitamin E (Vit E) on alcoholic steatohepatitis (ASH) in rats. ASH was induced by ethanol (3 times; 5 g/kg; 12 h intervals, via gavage), followed by a single dose of lipopolysaccharide (LPS; 10 mg/kg; i.p.). CAR (250 mg/kg; i.p.) and Vit E (200 mg D-alpha-tocopherol/kg; via gavage) were administered 30 min before and 90 min after the LPS injection. CAR treatment lowered high serum transaminase activities together with hepatic histopathologic improvements in rats with ASH. Reactive oxygen species formation, malondialdehyde levels, myeloperoxidase activities and transforming growth factor beta 1 (TGF-beta 1) and collagen 1 alpha 1 (COL1A1) expressions were observed to decrease. These improvements were more remarkable in CAR plus Vit E-treated rats. Our results indicate that CAR may be effective in suppressing proinflammatory, prooxidant, and profibrotic factors in the liver of rats with ASH. (C) 2015 Elsevier B.V. All rights reserved.
