Ileal interposition reduces oxidative stress via oxidant-antioxidant enzymes in rats with metabolic syndrome

Abstract

Purpose: This study aims to examine the effect of ileal transposition (IT) on plasma levels of the total antioxidant status (TAS), total oxidant status (TOS), Oxidative Stress Index (OSI), Superoxide dismutase (SOD), Nicotinamide adenine dinucleotide phosphate oxidase (NOX), Catalase (CAT), Reduced Glutathione (GSH) in both rats with Metabolic syndrome (MetS) and healthy controls. Materials and Methods: In the MetS model, newborn male Wistar albino rats were given MSG (4 g/mg) on days 0, 2, 4, 6, 8, and 10. The control group was injected only saline. In the 5th month, sham and IT animals underwent selected surgery. 2 months after surgery TOS, TAS, OSI, SOD, NOX, CAT, and GSH levels were assessed in the plasma. Results: IT procedure significantly increased SOD and CAT levels in MetS + IT group when compared to the MetS group (SOD; MetS 1.75 +/- 0.04, MetS+IT 2.1 +/- 0.15, CAT; MetS 32.02 +/- 1.73, MetS+IT 41.64 +/- 1.18,). As expected, while GSH levels was increased in MetS+IT rats compared to MetS rats, but the difference was not significant (MetS 243.31 +/- 6.36, MetS+IT 269.76 +/- 9.17). The NOX activity was significantly lower in MetS+IT group than MetS and MetS+S groups (MetS 610.35 +/- 26.25, MetS+IT 348.86 +/- 14.12). Conclusion: These data revealed the healing effect of IT surgery against oxidative stress associated with MetS. The available data endorses IT surgery as an effective strategy to reduce oxidative damage in rats with MetS by modulating systemic oxidant and antioxidant responses.
