Effects of single-dose neuropeptide Y on levels of hippocampal BDNF, MDA, GSH, and NO in a rat model of pentylenetetrazole-induced epileptic seizure
Epilepsy is one of the most common neurological disorders, characterized by recurrent seizures, which may increase the content of reactive oxygen and nitrogen species. Th e objective of this study was to investigate the eff ects of Neuropeptide Y on oxidative and nitrosative balance and brain-derived neurotrophic factor levels induced by pentylenetetrazole (a standard convulsant drug) in the hippocampus of Wistar rats. Th ree groups of seven rats were treated intraperitoneally as follows: group (saline + saline) ml saline, group (salin + Pentylenetetrazole) ml saline min before Pentylenetetrazole; and group (Neuropeptide Y + Pentylenetetrazole) μg/kg Neuropeptide Y min before mg/kg Pentylenetetrazole. After h, the animals were euthanized by decapitation. Hippocampus were isolated to evaluate the malondialdehyde, glutathione, nitric oxide, and brain-derived neurotrophic factor levels in three rat groups. Th e results of this study demonstrated that while intraperitoneally administered neuropeptide Y did not result in a statistically signifi cant diff erence in BDNF levels, its administration caused a statistically signifi cant decrease in malondialdehyde and nitric oxide levels and an increase in glutathione levels in rats with pentylenetetrazole-induced epileptic seizure. Neuropeptide Y were able to reduce nitroxidative damage induced by pentylenetetrazole in the hippocampus of Wistar rats.
