The present study was designed to investigatethe protective effect of aloin against alcoholic liver disease ina chronic alcohol feeding mouse model. Mice were givenalcohol twice a day by intragastric administration for11 weeks (4.0, 4.7, 5.5 g/kg bw/day for the first 3 weeksrespectively, 6.3 g/kg bw/day for the following 8 weeks). Aloin (10, 30 mg/kg bw) or vehicle was given by gavage tomice after each alcohol administration. Alcohol elevated theserum transaminases alanine aminotransferase, aspartateaminotransferase, total cholesterol and triglyceride levelswhich were significantly attenuated by the co-administrationof aloin (p\0.05). Histopathological observations wereconsistent with these indices. Co-administration of aloinsignificantly suppressed the alcohol-dependent induction ofsterol regulatory element-binding protein-1c expression(p\0.01) and remarkably up-regulated themRNA levels ofAMP-activated protein kinase-a2 (p\0.001). Furthermore,aloin supplementation significantly inhibited the alcoholdependentelevation of malondialdehyde and cytochromeP4502E1 expression (p\0.05), and significantly elevatedsuperoxide dismutase activity (p\0.01). The up-regulationof serum lipopolysaccharide (LPS), hepatic nitric oxide,tumor necrosis factor a, toll-like receptor-4, and myeloiddifferentiation primary response gene 88 were also markedlysuppressed by the co-administration of aloin (p\0.05) inalcohol-treated mice. These results suggest that aloin mayrepresent a novel, protective strategy against chronic alcoholicliver injury by attenuating lipid accumulation, oxidativestress and LPS-induced inflammatory response.
