摘要

Objective.The effects of hydroalcoholic extract ofTeucrium poliumand metformin on diabetes-induced memory impairment and brain tissues oxidative damage were investigated.Methods.The rats were divided into: (1) Control, (2) Diabetic, (3) Diabetic-Extract 100 (Dia-Ext 100), (4) Diabetic-Extract 200 (Dia-Ext 200), (5) Diabetic-Extract 400 (Dia-Ext 400), and (6) Diabetic-Metformin (Dia-Met). Groups 3–6 were treated by 100, 200, and 400 mg/kg of the extract or metformin, respectively, for 6 weeks (orally).Results. In passive avoidance test, the latency to enter the dark compartment in Diabetic group was lower than that of Control group (P<0.01). In Dia-Ext 100, Dia-Ext 200, and Dia-Ext 400 and Metformin groups, the latencies were higher than those of Diabetic group (P<0.01). Lipid peroxides levels (reported as malondialdehyde, MDA, concentration) in the brain of Diabetic group were higher than Control (P<0.001). Treatment by all doses of the extract and metformin decreased the MDA concentration (P<0.01).Conclusions.The results of present study showed that metformin and the hydroalcoholic extract ofTeucrium poliumprevent diabetes-induced memory deficits in rats. Protection against brain tissues oxidative damage might have a role in the beneficial effects of the extract and metformin.
