Zingiber officinale Attenuates Seizure Frequency, Depression-Like Behavior and Memory Impairment in Experimental Temporal Lobe Epilepsy via Hippocampal Neuroprotection
摘要
This study investigates the anticonvulsant effects of Zingiber officinale on seizures, memory loss, depression, and hippocampal sclerosis in a temporal lobe epilepsy with hippocampus sclerosis (TLE-HS) model, a common form of drug-resistant epilepsy. A total of 21 Sprague-Dawley rats were divided into three groups: 1) Control (saline-treated), 2) Diseased (Lithium–Pilocarpine model + saline), and 3) Treated (Lithium–Pilocarpine model + Z. officinale). After TLE-HS induction, rats received oral treatments for 15 days. Seizures were monitored via Video/EEG for 15 days/24 h, behavioral tests assessed memory and depression (24 hours following the final monitoring session), and Nissl staining evaluated hippocampal neurons. The Z. officinale extract significantly reduced seizure frequency (p < 0.05), alleviated depressive symptoms (p < 0.05), and enhanced memory function (p < 0.05). Notably, treatment with Z. officinale provided significant neuroprotection in the Lithium–Pilocarpine-induced TLE-HS rat model. Z. officinale extract significantly reduced seizure frequency, alleviates depression, improves memory, and offers partial neuroprotection. Further studies are needed to elucidate its mechanism and potential for treating TLE-HS in humans.
