Two self-associating biopolymers, namely chitosan (Ch) and a high-molar-mass hyaluronan (HA), were used to prepare membranes with the aim to protect and to enhance the healing of injured skin. A mitochondrially-targeted antioxidant-MitoQ-was incorporated into the mixture of biopolymers prior to their self-association. These three-component membranes were evaluated in detail utilising surface roughness measurements, contact angle measurements, hemocompatibility, and thrombogenicity analyses. Furthermore, in vivo application of Ch/HA/MitoQ membranes was assessed on injured rabbit and rat skin utilizing histological methods. The results showed that the prepared thrombogenic Ch/HA/MitoQ membranes had higher roughness, which allowed for greater surface area for tissue membrane interaction during the healing processes, and lower cytotoxicity levels than controls. MitoQ-loaded composite membranes displayed superior healing properties in these animal models compared to control membranes.
两种自缔合生物聚合物,即壳聚糖(Ch)和高分子量透明质酸(HA),被用于制备旨在保护和促进受损皮肤愈合的膜。在生物聚合物自缔合之前,将线粒体靶向抗氧化剂MitoQ掺入其混合物中。利用表面粗糙度测量、接触角测量、血液相容性和血栓形成分析对这些三组分膜进行了详细评估。此外,利用组织学方法在受伤的兔和大鼠皮肤上评估了Ch/HA/MitoQ膜的体内应用。结果表明,所制备的具有血栓形成性的Ch/HA/MitoQ膜具有更高的粗糙度,这使得在愈合过程中组织与膜相互作用的表面积更大,且细胞毒性水平低于对照组。与对照膜相比,负载MitoQ的复合膜在这些动物模型中表现出优异的愈合性能。
