Abstract

In this study, the functional metabolites of () were screened to evaluate their possible role in accelerated functional retrieval after peripheral nerve injury (PNI). leaves were used for extract preparation using solvents of different polarities. Each dry extract was uniformly mixed in rodents' chow and supplemented daily at a dose rate of 2 g/kg body weight from the day of nerve crush until the completion of the trial. The sciatic functional index (SFI) and muscle grip strength were performed to assess the recovery of motor functions, whereas the hotplate test was performed to measure the regain of sensory functions. An optimal level of oxidative stress and a controlled glycemic level mediates a number of physio-biochemical pathways for the smooth progression of the regeneration process. Therefore, total oxidant status (TOS), total antioxidant capacity (TAC) and glycemic levels were analyzed in metabolite-enriched extract-treated groups compared to the control. The supplementation of polar extracts demonstrated a significantly high potential to induce the retrieval of sensory and motor functions. Further, they were highly effective in controlling oxidative stress, facilitating accelerated nerve generation. This study has highlighted as a sustainable source of nutritive metabolites and a valuable target for drug development.

摘要

在本研究中,对()的功能代谢产物进行了筛选,以评估它们在周围神经损伤(PNI)后加速功能恢复中可能发挥的作用。使用不同极性的溶剂从()叶中制备提取物。将每种干提取物均匀混入啮齿动物的食物中,并从神经挤压当天开始,以2 g/kg体重的剂量率每日补充,直至试验结束。通过坐骨神经功能指数(SFI)和肌肉握力来评估运动功能的恢复情况,而通过热板试验来测量感觉功能的恢复情况。最佳水平的氧化应激和可控的血糖水平介导了许多生理生化途径,以促进再生过程的顺利进行。因此,与对照组相比,对富含代谢产物的提取物处理组的总氧化剂状态(TOS)、总抗氧化能力(TAC)和血糖水平进行了分析。极性提取物的补充显示出显著的高潜力,可诱导感觉和运动功能的恢复。此外,它们在控制氧化应激、促进神经加速再生方面非常有效。本研究强调了()作为营养代谢产物的可持续来源和药物开发的有价值靶点。 (注:原文括号处内容缺失,翻译时保留括号)
