    Objectives. The aim of this study was to investigate the possible protective effects of melatonin and beta-D-glucan against ischemia-reperfusion (IR) injury in rats. Materials and Methods. Forty rats were randomly divided into 5 groups, each consisting of 8 animals, as follows. Sham group [S], IR group [C], IR + beta-Glucan group [beta], IR + melatonin group [MLT], IR + melatonin + beta-Glucan group [MLT + beta]. The rats in the C, beta, MLT and MLT + beta groups were subjected to IR for 60 min each. Melatonin (10 mg.kg(-1)) was intraperitoneally injected for a single dose 30 min before IR. beta-Glucan (50 mg.kg(-1).day(-1)) was orally administered for 10 days to rats. All of the rats were killed on day 11, and histological changes in the liver and tissue levels of oxidants and antioxidants were evaluated. Results. Malondialdehyde [MDA] level were significantly higher in the C group compared to the S group (p = 0.007). MDA level were significantly higher in the beta group compared to the MLT and MLT + beta groups (p = 0.007). Tissue antioxidant markers (superoxide dismut ase [SOD], glutathione-peroxidase [GPx], and catalase [CAT]) were significantly lower in the C group than the S group (p < 0.05). SOD levels were simply not significant in the beta group compared to the MLT and MLT + beta groups. CAT and GPx activities were significantly higher in the beta group compared to the MLT and MLT + beta groups (p = 0.004). The histological damage ameliorated in beta, MLT and MLT + beta groups compared to C group. Conclusion. Our results suggest that melatonin and beta-glucan combination pretreatment suppressed oxidative stress and increased antioxidant levels in an experimental rat model of liver IR injury
