pubmed:abstractText |
Application of ultraviolet light (UV-) irradiation to a photocrosslinkable chitosan (Az-CH-LA) aqueous solution resulted in an insoluble, flexible hydrogel like soft rubber within 60 s. The chitosan hydrogel could completely stop bleeding from a cut mouse tail within 30 s of UV-irradiation and could firmly adhere two pieces of sliced skins of mouse to each other. In order to evaluate its accelerating effect on wound healing, full thickness-skin incisions were made on the back of mice and subsequently an Az-CH-LA aqueous solution was added into the wound and irradiated with UV light for 90 s. Application of the chitosan hydrogel significantly induced wound contraction and accelerated wound closure and healing. Histological examinations also have demonstrated an advanced granulation tissue formation and epithelialization in the chitosan hydrogel treated wounds. The chitosan hydrogel due to its accelerating healing ability is considered to become an excellent dressing for wound occlusion and tissue adhesive in urgent hemostasis situations.
