ABSTRACT
Objective:
To study the hemostatic and adhesion-prevention properties of gelatin-chitosan crosslinked film after craniotomy.Methods:
Gelatin-chitosan crosslinked film was prepared by casting the mixed solution of dialyzed chitosan and gelatin after crosslinking with glutaraldehyde in freeze dryer. Bleeding time was recorded for bilateral back incisions (5 incisions on each side) in 4 New Zealand white rabbits. Incision on one side was treated with gelatin-chitosan crosslinked film, and on the other was treated with gauze. Hemoglobin amount in films or gauzes was measured to determine the hemostatic effect after bleeding. Bilateral craniotomies were performed at calvaria in 16 adult rabbits. A piece of gelatin-chitosan crosslinked film was put in one randomized side and the other side served as a control. The scar formation was evaluated grossly and histologically on week 2,4,8,12.Results:
Bleeding time and hemoglobin amounts in gelatin-chitosan crosslinked film group were superior to those in gauze group(P
