Scar reduction

摘要

A method of reducing scar formation at a wound site includes contacting the wound site with an effective scar reducing amount of a cross-linked polysaccharide having a positive charge and thereby reducing scar formation as the wound site heals. Such polysaccharide include bioabsorbable cross-linked dextrans or alginates. The positive charge may be provided by diethylaminoethyl (DEAE) moieties. The cross-linked polysaccharide can be applied to the wound site as a powder or bead. The cross-linked polysaccharide may also be contained in a composition including a pharmaceutically acceptable vehicle. Biocompatable surgical devices are provided with an effective scar reducing amount of a cross-linked polysaccharide having a positive charge which reduce scar formation at healing wound sites. A method of reducing TGF-beta activity is also provided.
