[A new branch of biotechnology--wound-healing substances based on polyaminosaccharides].

This article concerns itself with the recently developed field of biotechnology dealing with the production of polyaminosaccharide-based wound-healing preparations. A method of obtaining the wound-healing preparation Mycoran with antiburn properties is presented. Based on the histologic findings provided by medical and biological tests of the preparation and the data available in the literature on the role of polysaccharides as signal molecules and glycoconjugates, the possible mechanism of stimulating fibroblast proliferation by fungal chitin and chitosan during the wound-healing process is discussed.
