Abstract: (1491 Views)
Introduction: The present study was conducted to evaluate the effect of Chlorogenic Acid (CA) and Diazepam (DZP) on epileptic complication that induced by repetitive intra-peritoneal injections of Pentylenetetrazle (PTZ) in aged rats.
Methods: Twenty-four month-old male Wistar rats (age > 12 months, 300-350 g) were divided in 4 experimental groups. Animal in control group (PTZ + Vehicle) received only PTZ. Animal in treated groups (PTZ + DZP, PTZ + CA10 and PTZ + 25) received diazepam 2 mg/kg, CA 10 mg/kg, or CA 25 mg/kg. All drugs injection were performed 30 min prior to each PTZ injection. Epilepsy was induced by injection of subconvulsive dose of PTZ every other day until the rats were completely kindled or epileptic. After each PTZ injection, animal was monitored for 40 min and epileptic behaviors were scored. At the end of the study, rats were sacrificed and the brains removed for evaluation of histological changes and Brain Derived Neurothrophic Factor (BDNF) gene expression.
Results: CA at dose of 25 mg/kg reduced percent of Generalized Tonic-Clonic Seizure (GTCS) in aged rats (24%) in compared to control group (50%) (p < 0.05). The latencies to the start of GTCS were decreased in both dose of CA (p < 0.05). Also, the percent of survived neurons in rats treated with CA (154%) were significantly higher relative to that of control animals (100%) (p < 0.05). The mRNA levels of BDNF significantly increased in CA treated rats (p < 0.05).
Conclusion: Hence, these findings revealed that CA have antiepileptic, neuroprotective and trophic effects in aged rats. CA can protect aged brain from deteriorative processes and save neurons during epilepsy in rats.
