| Background and Objective: Diabetes mellitus (DM) in long-term is associated with learning and memory decline. Metformin is an anti-diabetic drug with antioxidant and memory-improving effects. Thus, this research study was conducted to assess the effect of metformin on learning and memory in diabetic rats. Materials and Methods: In the present study, male Wistar rats (n=32) were randomly assigned to 4 groups: control, control treated with metformin (200 mg/kg), diabetic, and diabetic treated with metformin (200 mg/kg). Diabetes was induced by streptozotocin (STZ) at a dose of 60 mg/kg. Metformin was administered i.p. at a dose of 200 mg/kg one week after STZ injection for 7 weeks. Blood sample was taken from retro-orbital plexus before STZ injection and 4 and 8 weeks after STZ injection to measure blood glucose level. Passive avoidance and Y maze tests were performed to evaluate learning and memory dysfunctions. Results: After 8 weeks, diabetic rats showed a significant cognitive decline in passive avoidance and Y maze tests that was significantly improved after metformin treatment. In addition, metformin exerted a significant hypoglycemic effect in this model of DM. Conclusion: This study clearly showed that treatment with metformin for 7 weeks could ameliorate cognitive decline in diabetic animals and part of its beneficial effect is due to its hypoglycemic effect. | ||
