| الوصف: | Permanent cerebral ischemia is a consequence of prolonged cerebral artery occlusion that results in severe brain damage. Neurotoxicity occurring after ischemia can induce brain tissue damage by destroying cell organelles and their function. Neferine is a natural compound isolated from the seed embryos of the lotus plant and has broad pharmacological effects, including blockading of the calcium channels, anti-oxidative stress, and anti-apoptosis. This study investigated the ability of neferine to reduce brain injury after permanent cerebral occlusion. Permanent cerebral ischemia in rats was induced by instigation of occlusion of the middle cerebral artery for 24 h. The rats were divided into 6 groups: sham, permanent middle cerebral artery occlusion (pMCAO), pMCAO with neferine and nimodipine treatment. To investigate the severity of the injury, the neurological deficit score and morphological alterations were investigated. After 24 h, the rats were evaluated to assess neurological deficit, infarct volume, morphological change, and the number of apoptotic cell deaths. In addition, the brain tissues were examined by western blot analysis to calculate the expression of proteins related to oxidative stress and apoptosis. The data showed that the neurological deficit scores and the infarct volume were significantly reduced in the neferine-treated rats compared to the vehicle group. Treatment with neferine significantly reduced oxidative stress with a measurable decrease in 4-hydroxynonenal (4-HNE), nitric oxide (NO), neuronal nitric oxide (nNOS), and calcium levels and an upregulation of Hsp70 expression. Neferine treatment also significantly decreased apoptosis, with a decrease in Bax and cleaved caspase-3 and an increase in Bcl-2. This study suggested that neferine had a neuroprotective effect on permanent cerebral ischemia in rats by diminishing oxidative stress and apoptosis. |
