Abstract: 

Background: Diabetes type I is accompanied with disturbances in cognitive skills, memory and learning. In this research, we evaluated the effect of resveratrol chronic treatment on learning and memory in diabetic male rats.
Material and Methods: Rats were divided into 4 groups: control, resveratrol-treated control, diabetic and resveratrol-treated diabetic groups. We used streptozotosin for inducing diabetes. Resveratrol (10mg/kg I.p.) was administered for 8 weeks. For evaluation of learning and memory, passive avoidance test and Y-maze task were used. For Statistical analysis, SPSS software and paired T-test and one-way ANOVA were used.
Results: Resveratrol decreased serum glucose in diabetic rats (P<0.01). In passive avoidance learning, there wasn’t any significant difference in initial latency between diabetic and treated-diabetic group. Also, a significant decrease of step latency was observed in diabetic and treated diabetic rats (P<0.01). In Y maze, Resveratrol improved alternation percentage in diabetic rats.
Conclusion: Probably due to different mechanism of long term and short term memory, long term resveratrol treatment didn’t improve memory and learning in passive avoidance learning. In Y maze, method for determining the spatial memory, resveratrol improved spatial memory in diabetic rats. Resveratrol not only regulates glucose in diabetic rats but also it improves short term memory.
