Abstract: BACKGROUND: The purpose of this study was to evaluate probable protective effects of resveratrol treatment on hepatic oxidative events in a rat model of metabolic syndrome (MetS).
METHODS: Thirty-two male adult rats were randomly divided into 4 groups: control, fructose, resveratrol, and fructose plus resveratrol. To induce MetS, fructose solution (20 % in drinking water) was used. Resveratrol (10 mg/kg/day) was given by oral gavage. All treatments were given for 8 weeks. Serum lipid profile, glucose and insulin levels, liver total oxidant status (TOS) levels and paraoxonase (PON), glutathione peroxidase (GPx), superoxide dismutase (SOD) and catalase (CAT) activities were analyzed.
RESULTS: Fructose-fed rats displayed statistically significant increases in TOS levels, and decreases in PON activity compared to the control group. Resveratrol treatment moderately prevented the decrease in liver PON activity caused by fructose. On the other hand, resveratrol, alone or in combination with fructose, did not change the TOS levels when compared to the fructose group. The SOD and CAT activities in all groups did not change.
CONCLUSION: In this experimental design, high-fructose consumption led to elevated TOS levels and low PON activities. The resveratrol therapy shown beneficial effects on PON activity. However, it was found to behave like a prooxidant when administered together with fructose and alone in some parameters. Our results can inspire the development of new clinical therapy in patients with MetS (Tab. 2, Ref. 34).
