摘要:

托吡酯是一种在临床广泛用于抗癫痫和抗偏头痛的药物,并且在创伤性脑损伤和脑卒中动物模型中显示出神经保护作用。实验旨在评估托吡酯对实验性创伤性脊髓损伤后继发性细胞损伤的影响。以重物坠落法建立胸段脊髓挫伤大鼠模型,然后以12h的间隔,4次灌胃40 mg/kg剂量的托吡酯。干预后,损伤脊髓组织丙二醛和蛋白羰基水平明显减少,还原型谷胱甘肽水平明显升高,而内皮型一氧化氮合酶、诱导型一氧化氮合酶、细胞凋亡蛋白酶激活因子1免疫反应明显减弱,同时模型大鼠运动功能有所恢复。研究数据提示,托吡酯通过抗氧和抗凋亡效应对胸段脊髓挫损有神经保护作用。

Abstract:

Topiramate (TPM) is a widely used antiepileptic and antimigraine agent which has been shown to exert
neuroprotective effects in various experimental traumatic brain injury and stroke models. However, its utility in spinal cord injury has not been studied extensively. Thus, we evaluated effects of TPM on secondary cellular injury mechanisms in an experimental rat model of traumatic spinal cord injury (SCI). After rat models of thoracic contusive SCI were established by free weight-drop method, TPM (40 mg/kg) was given at 12-hour intervals for four times orally. Post TPM treatment, malondialdehyde and protein carbonyl levels were significantly reduced and reduced glutathione levels were increased, while immunoreactivity for endothelial nitric oxide synthase, inducible nitric oxide synthase, and apoptotic peptidase activating factor 1 was diminished in SCI rats. In addition, TPM treatment improved the functional recovery of SCI rats.This study suggests that administration of TPM exerts neuroprotective effects on SCI.
