Abstract:
Objective To investigate the effects of resveratrol on epileptic seizure and cognitive impairment and the role of CREB in rats with temporal lobe epilepsy (TLE). Methods TLE rat model was established by LiCl?pilocarpine injection and resveratrol was administrated at a dose of 15 mg/(kg · d) for 7 days. The rat behavior was evaluated by Racine scale and the CREB expression and phosphorylation in temporal cortex were detected with western blot. The Morris water maze was used to assess the learning and memory. Results Resveratrol administra?tion significantly reduced the Racine scales of TLE rats. The CREB phosphorylation in TLE group was increased compared with that in control group, which was remarkably inhibited by resveratrol. The escape latency of TLE group was increased at 4th, 5th and 6th day after training, and time in target quadrant was reduced compared with that in control group. Resveratrol significantly decreased latency time and increased target quadrant time of TLE rats. Conclusion In TLE rats, resveratrol administration suppresses epileptic seizure and improves cognitive function, which might be mediated by inhibition of CREB phosphorylation.
