THE EFFECT OF AEROBIC EXERCISE WITH MELATONIN ON RAGE GENE EXPRESSION AND SOME INDICATORS OF OXIDATIVE STRESS IN MALE RATS WITH DIABETIC NEUROPATHIC PAIN

Background: Neuroinflammation and oxidative stress play a pivotal role in the diabetic neuropathic pain. The aim of this study was to evaluate the effect of aerobic exercise with melatonin on RAGE gene expression and some indicators of oxidative stress in rats with diabetic neuropathic pain Methods: Forty 8-week-old male Wistar rats (weight range 204 ± 11.3 g) were randomly divided into five of 8 groups including: diabetic neuropathy (50 mg / kg streptozotocin intraperitoneal injection), diabetic melatonin neuropathy (mg / kg 10 melatonin daily for 6 weeks), diabetic neuropathy exercise (30 minutes of aerobic exercise at 15 meters per minute, 5 days a week for 6 weeks), diabetes melatonin neuropathy and healthy exercise and control. After confirmation of diabetic neuropathy by behavioral tests, exercise protocol and supplementation were performed. RAGE gene expression was measured by real-time technique and oxidative stress indices in spinal cord tissue by spectrophotometer. One-way analysis of variance and Tukey's post hoc test were used for statistical analysis. Results: Exercise and melatonin reduced the sensitivity of the nervous system to thermal hyperalgesia and mechanical allodynia. Aerobic exercise with melatonin significantly reduced RAGE gene expression and MAD concentration and increased the activity of SOD and CAT enzymes compared to the diabetic neuropathy group (P <0.05). Conclusion: Aerobic exercise with melatonin modulates the expression of RAGE gene and oxidative stress indices and improves the sensitivity of nociceptors to pain factors. It is recommended to use aerobic exercise with melatonin for diabetics to reduce neuropathic pain.
