Abstract

The foam dressing material continuously absorbs the exudate of the wound area and maintains moisture environment, so that there is a weak point of the bacterial growth. Therefore, antimicrobial property is one of the important factors in the development of moisture environment foam dressing. The purpose of this study is to evaluate the effectiveness of wound dressing after manufacturing antimicrobial foam dressing materials containing asiatic acid, madecassic acid, and aciaticoside of the Centella asiatica. In order to fabricate superior absorbent layer compared to conventional polyurethane foam dressings, the optimum mechanical properties, pore morphology, absorbency and absorption rate were established on blending ratio of the foam mixture and the antimicrobial component. The foam containing the active ingredients of the Centella asiatica showed high antimicrobial activity and excellent wound recovery rate in animal model experiments. The polyurethane foam dressing material containing active ingredients of the Centella asiatica is expected to be used as an antimicrobial wound treatment.


폼 드레싱재는 창상부위의 삼출물을 지속적으로 흡수하며 습윤환경을 유지하므로, 세균증식의 취약점이 있다. 그러므로 습윤환경 폼 드레싱재의 개발에서 항균성 부여는 중요한 요소 중 하나이다. 본 연구에서는 천연 항균물질인 병풀의 유효성분(asiatic acid, madecassic acid, aciaticoside)을 활용하여 항균성 폼 드레싱재를 제조 후 창상치료 효과를 검증하고자 하였다. 기존의 창상피복용 폴리우레탄 폼 드레싱재의 물성보다 개선된 흡수층을 제조하기 위해 발포혼합액과 항균성분의 배합비에 따른 기계적 물성, 기공형태, 흡수도 및 흡수속도를 분석 후 최적조건을 확립하였다. 병풀의 유효성분을 함유한 폼은 높은 항균능을 나타내었으며 동물모델 실험에서 우수한 창상회복률을 보여주었다. 병풀의 유효성분이 함유된 폴리우레탄 폼 드레싱재는 항균성 창상치료용 소재로서의 응용 가능성이 기대된다.
