Abstract:

Sesame oil is regarded as a daily nutritional supplement to increase cell resistance to lipid peroxidation. The aims of this study were to examine the effects of parenteral sesame oil on oxidative stress and hepatic disorder induced by lipopolysaccharide and to determine the defense mechanisms involved in sesame oil-associated anti-oxidative effects in rats. Oxidative stress was induced by lipopolysaccharide (5 mg/kg, intraperitoneally) and assessed by determination of lipid peroxidation. Sesame oil (8 ml/kg, subcutaneously) was given 3 h after lipopolysaccharide, and lipid peroxide levels, hydroxyl radical, superoxide anion, the enzyme activities of superoxide dismutase and catalase as well as the levels of glutathione and nitrite were examined 6 h after lipopolysaccharide. Hepatic function was assessed by determining the activities of serum aspartate aminotransferase and alkaline phosphatase. Sesame oil reduced lipid peroxidation and hydroxyl radical, but failed to affect superoxide anion. Superoxide dismutase and catalase were increased, but glutathione was not affected, and the levels of nitrite were reduced. Further, sesame oil-treated groups showed attenuated hepatic disorder in lipopolysaccharide-treated rats. Thus, parenteral sesame oil can be used to attenuate oxidative stress and relieve hepatic disorder after lipopolysaccharide intoxication in rats.
