Preparation, Characterization and Wound Healing Effect of β Chitosan and Gelatin Hydrogels from Sepia Officinalis: In Vivo Study

Wound healing is a fundamental process through which the body repairs itself following damage to the skin's integrity. This process is intricate and involves multiple biological mechanisms. The objective of this study is to assess the wound healing properties of β-chitosan and gelatin hydrogels. Twenty-five rats were divided into five groups to facilitate the evaluation of wound closure rates and histopathological changes. Upon analyzing the results, we noted a decrease in the initial surface area of all wounds examined. The extent of contraction varied depending on the type of hydrogel used. By day 14, the contraction was most significant in the hydrogel (ch + gel) group (97.30%), followed closely by β-chitosan (96.72%) and gelatin (96.63%), as well as the cicatryl-bio treatment (92.76%).
