Abstract

The authors investigated the effect of curcumin on markers of oxidative stress and liver damage in rats that chronically ingested alcohol and heated oil. Nine groups of ten Wistar male rats received combinations of curcumin 100 mg/kg body weight daily, ethanol 5 mg/kg, 15% dietary sunflower oil and 15% heated sunflower oil for 12 weeks. Serum and liver tissue were collected. Groups 4-6, which had received compounds causing oxidative stress, showed increased serum aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, total bilirubin, cholesterol, triglycerides, low density lipoprotein, very low density lipoprotein and reduced high density lipoprotein, protein and albumin, compared with the controls. Reductions were observed in glutathione peroxidase and reductase gene expression, superoxide dismutase activity, glutathione peroxidase activity, glutathione reductase activity, reduced glutathione concentration and catalase enzyme activity. Groups 7, 8 and 9 which received curcumin with heated oil, ethanol or both, showed lower elevations in serum and oxidative damage markers compared with the corresponding non-curcumin treated groups. It can be concluded that curcumin reduces markers of liver damage in rats treated with heated sunflower oil or ethanol.
