The effects of Brazilian chitosan-based biomaterials on wound healing in rats.

The use of natural supplies is a resource to mimic an original extracellular matrix that allows for migration, proliferation, and cellular organization. Chitosan from Brazilian Atlantic Ocean had low protein, minerals percentage and excellent antibacterial activity. The aim of this study was to evaluate and to compare the effectiveness of different types of acids as solvents with Brazilian chitosan-membrane in the healing process of skin lesions.
