This research focused on to know the influence of chitosan applied to wound healing process on male mice skin with macroscopic observation parameters such as size of wound, dryness of wound, and condition of granulation tissue also other parameter in histopathology observation such as inflammation cell infiltrate, neocapilarization, re-epitelization, and forming of connective tissue.

Observation and take skin sample were conducted at 0th, 2nd, 4th, and 6th day after wounding at 3 mice from each group. Statistically, chitosan have the ability speed up process of wound healing because it􀂶s significantly different compared to negative control.
