Abstract:
The aim of this study was to compare the capacity of the collagen products Biopad (Euroresearch, Milano, Italy), Promogran (Systagenix Wound Management, Quincy, Massachusetts), Colactive (Smith & Nephew, St Petersburg, Florida), and Puracol (Medline Industries, Mundelein, Illinois) to interact with biological tissues and to start restoring the healing process. These results demonstrate how these products can interact differently with enzymes and cells that characterize the environment of a healing wound.
