The impact of peripheral nerve damage on a patient's quality of life is severe. The most frequent peripheral nerve crush damage is a sciatic nerve injury. Previous research has shown that glibenclamide (GB) has neuroprotective properties in a variety of oxidative stress-related disorders, including Alzheimer and Parkinson. The goal of this study was to see how GB affected nerve regeneration and improved function of the sciatic nerve in a rat model following a crush injury. We evaluated motor function, sensory recovery, gene expression, and histomorphometry following damage at different time points. Additionally, we assessed atrophy in the gastrocnemius muscle using histology and mass ratio analyses. Our results suggest that 2, 4, 6, and 8 weeks following glibenclamide therapy, promotes the recovery of motor and sensory function in the injured site. Following glibenclamid injection, the mRNA levels of neurotrophic factors (NGF and BDNF) are raised. According to histomorphometry assessment, glibenclamide injection also increased the number of myelinated fibers while decreasing their thickness. These results showed that glibenclamide therapy by decreasing the proinflammatory and oxidant factors may enhance the nerve regeneration. It is clear that more research is needed to confirm these findings.
周围神经损伤对患者生活质量的影响极为严重。最常见的周围神经挤压损伤是坐骨神经损伤。先前的研究表明,格列本脲(GB)在包括阿尔茨海默病和帕金森病在内的多种与氧化应激相关的疾病中具有神经保护特性。本研究的目的是观察GB对大鼠坐骨神经挤压损伤模型中神经再生和功能改善的影响。我们在不同时间点评估了损伤后的运动功能、感觉恢复、基因表达和组织形态计量学。此外,我们使用组织学和质量比分析评估了腓肠肌的萎缩情况。我们的结果表明,格列本脲治疗2、4、6和8周后,可促进损伤部位运动和感觉功能的恢复。注射格列本脲后,神经营养因子(NGF和BDNF)的mRNA水平升高。根据组织形态计量学评估,注射格列本脲还增加了有髓纤维的数量,同时减小了其厚度。这些结果表明,格列本脲治疗通过降低促炎和氧化因子可能会增强神经再生。显然,需要更多的研究来证实这些发现。
