Infections are severe complications associated with chronic wounds and tardy healing that should be timely treated to achieve rapid and proper tissue repair. To hinder such difficulties, a nanofibrous mat composed of polyvinyl alcohol and chitosan (PVA/CS) was developed by electrospinning method, containing thyme () and ginger () extracts. The mat containing 10 wt% of the extracts (at the ratio of 50:50) exposed the nanofibers (NFs) with the nanoscale diameter (average 382 ± 60 nm), smooth surface, and defect-free morphology. Likewise, the relevant analyses of the loaded mat displayed high wettability, porosity, and liquid absorption capacity without any adverse interaction. The obtained mat also provided a high antioxidant activity, and its release profile was continuous and sustained for nearly 72 h. Besides, it inhibited the growth of both Gram-positive and Gram-negative strains. Furthermore, the proposed mat significantly accelerated cutaneous wound healing in bacterial-infected rats by preventing bacteria growth at the wound site. At last, histopathology analysis confirmed the ample regeneration of skin structures, forming collagen fibers and appendages. Overall, the proposed mat containing ginger-thyme extracts provides multiple therapeutic capabilities with promising solutions for inhibiting wound infection and accelerating the healing process.
感染是与慢性伤口和愈合迟缓相关的严重并发症,应及时治疗以实现快速且适当的组织修复。为了克服这些困难,通过静电纺丝法制备了一种由聚乙烯醇和壳聚糖(PVA/CS)组成的纳米纤维垫,其中含有百里香()和姜()提取物。含有10 wt%提取物(比例为50:50)的垫子呈现出具有纳米级直径(平均382±60 nm)、表面光滑且无缺陷形态的纳米纤维(NFs)。同样,对负载垫子的相关分析显示出高润湿性、孔隙率和液体吸收能力,且没有任何不良相互作用。所获得的垫子还具有高抗氧化活性,其释放曲线连续且持续近72小时。此外,它抑制了革兰氏阳性菌和革兰氏阴性菌的生长。此外,所提出的垫子通过防止伤口部位细菌生长,显著加速了细菌感染大鼠的皮肤伤口愈合。最后,组织病理学分析证实了皮肤结构的充分再生,形成了胶原纤维和附属器。总体而言,所提出的含有姜 - 百里香提取物的垫子具有多种治疗能力,为抑制伤口感染和加速愈合过程提供了有前景的解决方案。
