  • Wound healing composition using squid chitin and fish skin collagen
    Patent number: 5698228
    Abstract: There is provided a skin substitute that can suitably be used for covering the surface of a damaged skin area which is typically a wound produced by a traumatic local loss of the skin of the human body as a result of a burn or some other cause of damage. It is a skin substitute of a laminate comprising a squid chitin sheet and a fish skin collagen coat layer, which may be a salmon skin collagen coat layer. Such a skin substitute effectively exploits the suppleness and the effect of proving an environment for encouraging the production of lysozyme and defending the wound of squid chitin and, at the same time, compensate the disadvantage of poor adhesion of fibroblast cells that operate for curing the wound.
