An anti-amnesic effect of water extract from Dendropanax morbifera Lev. leaves (DMW) on memory dysfunction in streptozotocin-induced diabetic rats was investigated to assess its potential industrial value. Daily administration of DMW (11 weeks) significantly reduced serum glucose, insulin, and blood urea nitrogen (BUN) levels increased by an intraperitoneal injection of streptozotocin (STZ, 55 mg/kg). In addition, the administration of DMW decreased escape latency and increased the time spent in the platform quadrant in the Morris water maze test. Step-through latency in a passive avoidance test was also improved. Finally, DMW produced ameliorating effects on STZ-induced cholinergic deficit through an inhibitory effect on acetylcholinesterase and the increment of acetylcholine level in the hippocampus. These results suggest that DMW might be used as a natural substance for improving diabetic induced cognitive impairment.
