Spinal cord injury (SCI) is a debilitating condition characterized by partial or complete loss of motor and sensory function caused by mechanical trauma to the spinal cord. Novel therapeutic approaches are continuously explored to enhance spinal cord regeneration and functional recovery.
In this study, we investigated the efficacy of the poly(vinyl alcohol) and chitosan (PVA/CS) scaffold loaded with different thymol concentrations (5, 10, and 15 wt%) in a rat compression model for SCI treatment compare to other (e.g., thymol and scaffold) control groups.
The thymol-loaded scaffold exhibited a smooth surface and a three-dimensional nanofibrous structure with nanoscale diameter. The conducted analyses verified the successful incorporation of thymol into the scaffold and its high water absorption, porosity, and wettability attributes. Behavioral assessment of functional recovery showed improving sensory and locomotor impairment. Furthermore, histopathological examinations indicated the regenerative potential of the thymol-loaded nanofiber scaffold, by neuronal survival.
Therefore, these findings suggest that the thymol-loaded nanofibrous scaffolds have promising pharmacological activities for alleviating neuropathic pain and addressing complications induced by SCI.
脊髓损伤(SCI)是一种使人衰弱的病症,其特征是脊髓受到机械创伤导致运动和感觉功能部分或完全丧失。人们不断探索新的治疗方法以促进脊髓再生和功能恢复。
在本研究中,我们研究了负载不同百里香酚浓度(5%、10%和15%重量)的聚乙烯醇和壳聚糖(PVA/CS)支架在大鼠脊髓损伤压缩模型中的治疗效果,并与其他对照组(如百里香酚和支架对照组)进行比较。
负载百里香酚的支架表面光滑,具有纳米级直径的三维纳米纤维结构。进行的分析证实了百里香酚成功掺入支架中,以及其高吸水性、孔隙率和润湿性等特性。功能恢复的行为评估显示感觉和运动障碍有所改善。此外,组织病理学检查表明,负载百里香酚的纳米纤维支架具有神经元存活所显示的再生潜力。
因此,这些发现表明,负载百里香酚的纳米纤维支架在减轻神经性疼痛和解决脊髓损伤引起的并发症方面具有有前景的药理活性。
