Abstract

Wound care is a health industry concern affecting millions worldwide. Recent increase in metabolic disorders such as diabetes comes with elevated risk of wound-based complications. Treatment and management of wounds are difficult practices due to complexity of the wound healing process. Conventional wound dressings and treatment applications only provide limited benefits which are mainly aimed to keep wound protected from external factors. To improve wound care, recent developments make biopolymers to be of high interest and importance to researchers and medical practitioners. Biopolymers are polymers or natural origin produced by living organisms. They are credited to be highly biocompatible and biodegradable. Currently, studies reported biopolymers to exhibit various health beneficial properties such as antimicrobial, anti-inflammatory, hemostatic, cell proliferative and angiogenic activities which are crucial for effective wound management. Several biopolymers, namely chitosan, cellulose, collagen, hyaluronic acid and alginic acid have been already investigated and applied as wound dressing agents. Different derivatives of biopolymers have also been developed by cross-linking with other molecules, grafting with other polymers, and loading with bioactive agents or drugs which showed promising results towards wound healing without any undesired outcome such as scarring and physiological abnormalities. In this review, current applications of common biopolymers in wound treatment industry are highlighted to be a guide for further applications and studies.

상처 치료는 전세계 인류에 영향을 미치는 보건 산업계의 관심사다. 당뇨병과 같은 대사증후군 유병률 증가로 상처에 의한 합병증의 위험이 높아지고 상처치유의 복잡함 때문에 상처의 치료와 관리가 어렵다. 전통적 상처 드레싱은 제한된 보호기능을 제공하며, 상처 드레싱의 치료 능력을 향상시키기 위해 생체고분자 기반의 드레싱들이 개발되고있다. 생체고분자는 생분해성이 뛰어나고 생체적합성이 좋으며 효과적인 상처 관리에 중요한 항균, 항염증, 지혈, 세포증식, 혈관성 활동 등 다양한 효과가 있다. 키토산, 셀룰로오스, 콜라겐, 히알루론산, 알긴산 등의 여러 생체고분자가 이미 상처치유제로 활용되고 있으며 생체고분자를 다른 고분자, 생체활성 분자 및 약물과 결합하여 생리학적 문제 없이 흉터를 최소화하는 새로운 상처 드레싱이 개발되고 있다. 본 논문에서는, 향후의 연구와 활용을 위한 현재의 생체고분자의 상처처리에 대해 알아보았다.
