摘要:
The present invention relates to a hemostatic dressing which comprises a plurality of layers that contain resorbable materials and/or coagulation proteins. In particular, the invention includes dressings in which a layer of thrombin is sandwiched between a first and second layer of fibrinogen and wherein the layer of thrombin is not coextensive with the first and/or second layer of fibrinogen. The hemostatic dressings are useful for the treatment of wounded tissue.

摘要:
The present invention relates to a haemostatic multilayer bandage that comprises preferably a thrombin layer between two fibrinogen layers. The dressing may contain other resorbable materials such as glycolic acid or lactic acid based polymers or copolymers. The inventive haemostatic bandage is useful for the treatment of wounded tissue.

摘要:
This invention provides methods for the preparation of a tissue sealant-treated biomaterial, wherein the tissue sealant used in the method comprises at least one composition which is selected from one or more antibodies, analgesics, anticoagulants, anti-inflammatory compounds, antimicrobial compositions, antiproliferatives, cytokines, cytotoxins, drugs, growth factors, interferons, hormones, lipids, demineralized bone or bone morphogenetic proteins, cartilage inducing factors, oligonucleotides polymers, polysaccharides, polypeptides, protease inhibitors, vasoconstrictors or vasodilators, vitamins, minerals, stabilizers and the like. Further provided are the biomaterial prepared therefrom, including vascular grafts.
摘要:
Methods are disclosed for sterilizing preparations of glycosidases to reduce the level therein of one or more active biological contaminants or pathogens, such as viruses, bacteria (including inter- and intracellular bacteria, such as mycoplasmas, ureaplasmas, nanobacteria, chlamydia, rickettsias), yeasts, molds, fungi, single or multicellular parasites, prions or similar agents responsible, alone or in combination, for TSEs. These methods involve sterilizing preparations of glycosidases, such as alpha-glucosidase or alpha-galactosidase, with irradiation.
摘要:
This invention is directed to the preparation and utilization of supplemented chitin hydrogels, such as chitosan hydrogels. Further provided are biomaterials comprising same. The particular supplement delivered by the chitin hydrogel is selected as a function of its intended use. In one embodiment, this invention provides a composition of matter, comprising a chitin hydrogel or chitin-derived hydrogel, wherein the hydrogel does not inhibit full-thickness skin wound healing.
