| خلاصه مقاله | Background and Aim: To date, beneficial effects of voluntary exercise have been shown in improving diabetes-induced lung damage, but the main mechanism of its therapeutic effects have not yet been determined. Therefore, in this study, the effect of voluntary exercise on inflammatory cytokines, NF-ΚB, Nrf2 levels in lung tissue of type 2 diabetic rats was investigated.
Methods: 28 male Wistar rats were allocated into four groups as follow; control group (C), exercise group (Exe), Diabetic group (Dia), diabetic +exercise (Dia- Exe). Type 2 diabetes was induced in the diabetic groups by high-fat diet for 4 weeks and intraperitoneal injection of streptozotocin (35 mg/kg). In exercise groups, animals exercised voluntarily for 10 weeks. At the end of intervention, the animals were killed by ketamine and xylazine injections, and their lung tissue was removed and IL-10, IL-11, NF-kB and Nrf2 protein levels were measured.
Results: Data showed a reduction in lung tissue levels of IL-11, IL-10 and Nrf2 of diabetic groups compared to control group. Also findings showed an increase in NF-kB level in lung tissue of diabetic group compared to the C group. Voluntary exercise inhibited diabetic-induced changes.
Conclusion: Voluntary exercise could decrease diabetic -induced pathological changes in lung tissue via the modulation of IL-10, IL-11, NF-kB and Nrf2 protein levels. |
