Abstract: Natural polymer chitin and chitosan exhibit a variety of physicochemical and biological properties including biocompatibility，biodegradability，nontoxicity. Their hemostatic，antimicrobial，wound healing and tissue regeneration effects make them a very attractive substance for wound dressing. This paper reviews current research of medical dressing based on chitin/chitosan.

摘要： 天然高分子甲壳素和壳聚糖具有良好的物化性质、生理活性、生物相容性和生物可降解性，无有害降解物，具有止血和抑菌作用，可促进伤口愈合和组织修复再生，在医用敷料方面有广阔的应用前景。本文综述了近几年甲壳素和壳聚糖作为医用敷料的研究进展。
