Introduction: Diabetes mellitus is a metabolic disease. This disease is almost associated with depression and impaired pain sensation. Stevia rebaudiana Bertoni (stevia) has a sweet taste and a useful effect in blood glucose control. This study was designed to evaluate the effect of Stevia and Nano-stevia on psychological problems (e.g. depression and pain) induced by diabetes.
Methods: By a single intraperitoneal administration of streptozotocin, diabetes mellitus was induced in male Wistar rats. Stevia (20 mg/dl per day for 30 days) and Nano-stevia (20 mg/dl per day for 30 days) were administrated intra-gastrically in diabetic rats. Using the forced swim test (FST) and formalin test, depression and pain behaviors were measured, respectively.
Results: The results exhibited that male diabetic rats showed hyperglycemia, depressant-related behavior, and hyperalgesic response. On the other hand, intra-gastrically usage of Stevia (20 mg/dl per day for 30 days) and Nano-stevia (20 mg/dl per day for 30 days) modified the hyperglycemia, depressant-related response, and hyperalgesic effect in diabetic rats. Nano-stevia indicated the maximum significant response rather than Stevia.
Conclusion: The results of this study indicate that Stevia and particularly Nano-stevia could be beneficial in managing diabetes and its associated behavioral complications.
