Effect of alpha lipoic acid, melatonin and trans resveratrol on intracerebroventricular streptozotocin induced spatial memory deficit in rats.
In the present study, the effect of antioxidants-alpha lipoic acid, melatonin and trans resveratrol were studied against intracerebroventricular streptozotocin induced spatial memory deficit. Male Wistar rats were injected with intracerebroventricular streptozotocin bilaterally. The rats were treated chronically with alpha lipoic acid (200 mg/kg, po), melatonin (20 mg/kg, ip) and trans resveratrol (20 mg/kg, ip) for 18 days starting from day 1 of streptozotocin injection in separate groups. The spatial memory was evaluated using the Morris water maze task. The intracerebroventricular streptozotocin rats treated with antioxidants showed significantly less spatial memory deficit both in the acquisition and probe trials as compared to the vehicle treated rats. The study demonstrated the effectiveness of alpha lipoic acid, melatonin and trans resveratrol in preventing spatial memory deficit induced by intracerebroventricular streptozotocin and it's potential in age related neurodegenerative disorders where oxidative stress is involved such as Alzheimer's disease.
