In the present study polyelectrolyte complexes (PECs) based on new sulfadiazine-chitosan conjugates with sodium hyaluronate have been developed with potential use in treatment of burn wounds. The PECs were chemically characterized using Fourier Transform-Infrared Spectroscopy, Scanning Electon Microscopy and Near Infrared Chemical Imaging Technique. The swelling behavior and sulfadiazine release were also investigated. The antimicrobial activity was evaluated towards three bacterial strains: , and . The developed PECs demonstrated their antimicrobial efficiency against tested bacterial strains, the PECs containing sulfadiazine-modified chitosan being more active than PECs containing unmodified chitosan.
在本研究中,基于新型磺胺嘧啶-壳聚糖共轭物与透明质酸钠的聚电解质复合物(PEC)已被开发出来,具有用于治疗烧伤创面的潜在用途。使用傅里叶变换红外光谱、扫描电子显微镜和近红外化学成像技术对PEC进行了化学表征。还研究了其溶胀行为和磺胺嘧啶释放情况。对三种细菌菌株: 、 和 评估了抗菌活性。所开发的PEC对测试的细菌菌株显示出抗菌效率,含有磺胺嘧啶修饰壳聚糖的PEC比含有未修饰壳聚糖的PEC更具活性。
