Abstract
Purpose: Diabetes is associated with memory and learning disorder. The purpose of this study is to determine the effect of acute oral administration of loganin on memory in diabetic male rats. Methods: 42 male Wistar rats (250-300 g) were divided into six groups: Control, Diabetic (1 week), Diabetic (12 weeks), Loganin, Diabetic (1 week) + Loganin, Diabetic (12 weeks) + Loganin. Diabetes was induced by IP injection of Streptozotocin (60 mg/kg). Loganin (40 mg/kg, po) was administrated 1 hour before test. Then, spatial memory was compared between groups with Morris Water Maze tests. Results: Administration of loganin during acquisition, significantly (p<0.05) decreased both escape latency and traveled distance to find hidden platform in 1 and 12 weeks diabetic rats. In evaluation of recall phase of memory, loganin significantly (p<0.05) increased time and distance spent in the target quadrant in 1 and 12 weeks diabetic rats. Conclusion: Acute administration of loganin could improve spatial memory in diabetic rats.
