: Effective wound dressing is the key solution to combating the increased death rate and prolonged hospital stay common to patients with wounds. : Sodium alginate-based single- and double-layer membranes incorporated with root extract were designed using the solvent-casting method from a combination of polyvinyl alcohol (PVA), Pluronic F127 (PF127), and gum acacia. : The successful preparation of the membranes and loading of the extract were confirmed using Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD). The prepared membranes were biodegradable and non-toxic to human skin cells (HaCaT), with high biocompatibility of 92 to 112% cell viability and good hemocompatibility with absorbance ranging from 0.17 to 0.30. The membrane's highest water vapor transmission rate was 1654.7333 ± 0.736 g/m/day and the highest % porosity was 76%. The membranes supported cellular adhesion and migration, with the highest closure being 68% after 4 days compared with the commercial wound dressings. This membrane exhibited enhanced antimicrobial activity against the pathogens responsible for wound infections. : The distinct features of the membranes make them promising wound dressings for treating infected wounds.
有效的伤口敷料是解决伤口患者死亡率上升和住院时间延长这一常见问题的关键。基于海藻酸钠的单层和双层膜与根提取物结合,采用溶剂浇铸法,由聚乙烯醇(PVA)、普朗尼克F127(PF127)和阿拉伯胶组合而成。使用傅里叶变换红外光谱(FTIR)和X射线衍射(XRD)确认了膜的成功制备和提取物的负载。制备的膜可生物降解,对人皮肤细胞(HaCaT)无毒,具有92%至112%的高细胞活力生物相容性,以及0.17至0.30的良好血液相容性吸光度。膜的最高水蒸气透过率为1654.7333±0.736 g/m/天,最高孔隙率为76%。与商业伤口敷料相比,该膜支持细胞黏附和迁移,4天后最高闭合率为68%。该膜对导致伤口感染的病原体表现出增强的抗菌活性。这些膜的独特特性使其成为治疗感染伤口的有前景的伤口敷料。
