Abstract: Objective: To investigate the effects of aerobic exercise and glutamine (Gln) on anti-oxidative stress and inflammatory factors in type 2 diabetes mellitus (T2MD) rats. Methods: Diabetic rat model was induced by streptozotocin (STZ). Fifty 6-week old male SD rats were randomly divided into 5 groups (n=10), including quiet control group (N), diabetes control group (D), diabetic aerobic exercise group (DE), diabetic glutamine group (DG) and diabetic aerobic exercise glutamine group (DEG). After 6 weeks, the related indicators of glucose and lipid metabolism, anti-oxidative stress and inflammatory factors in diabetic rats were detected, and the possible mechanism affecting inflammatory response were explored. Results: Compared with group N, the levels of serum malondialdehyde(MDA), blood glucose, total cholesterol(TC), triglyceride(TG), insulin, leptin and tumor necrosis factor-α(TNF-α) in group D were increased significantly (P<0.01). Compared with group D, serum levels of MDA, blood glucose, TC, TG, insulin, leptin and TNF-α in three intervention groups were decreased significantly, while the levels of SOD, GSH-Px and adiponectin were increased, and the combined effect was more obvious (P<0.01). Conclusion: Both aerobic exercise and Gln can relieve the glucose and lipid metabolism and disturbance, oxidative stress injury and inflammation in diabetic rats.

Key words: glutamine, aerobic exercise, type 2 diabetes, rat, oxidative stress
