    • The invention pertains to a cover of wounds in the form of a powder or a dry powdery fluid and is useful in covering and treating of ulcerous and necrotic wounds. It consists of animal or fungous chitin and chitosan in a powdered form of particle size 0.01 to 0.3 mm or of crosslinked dextran in the form of spheric particles of diameter 0.05 to 0.5 mm and of an immobilized protease. Enzymes are chemically bonded to the structure of the biopolymeric carrier and provide cleaning of the wound by dissolution of undesirable protein material, in particular fibrin, necrotic tissues, components of pus, and the like. In addition the adsorption and regeneration effects of powder act to provide suction of exudate and purulent matter infected with bacteria into interstitial capillary space. The cover according to the invention acts by fast cleaning of necrotic defects and speeds up the granulation and healing of the wound. The invention can be utilized in pharmaceutical production.

    • The invention relates to a method for preparation of cationactive and amphoteric ion-exchangers from non-ionogenic crosslinked copolymers containing hydroxyl groups by their reaction with mineral acids, addition products of sulfur trioxide, sulfuric acid or chlorosulfuric acid with alcohols or pyridine, unsaturated compounds, as acrylonitrile, methacrylonitrile or sodium vinylsulfonate in a strongly alkaline medium, or with halogenoalkylammonium compounds. The starting copolymer containing hydroxyl groups is prepared by the suspension copolymerization of monomers, selected from the group which comprises hydroxyalkyl methacrylates and acrylates and oligoglycol acrylates and methacrylates, with crosslinking divinyl monomers, e.g. divinylbenzene, ethylene dimethacrylate, butylenediol dimethacrylate or diacrylate, and advantageously has the macroporous structure. The products are suitable for application in column process thanks to their favorable mechanical properties, namely for chromatographic separation of hydrophilic compounds, e.g. biological materials as aminoacids. The hydrophilicity of the product may be varied by selection of monomers for the starting copolymer, by the type of ionactive substitution and by the degree of transformation.

Resulting cellulose sorbents are suitable carriers and materials for chromatography. The invented methods consists in heating a viscose (an aqueous solution of sodium cellulose xanthate) suspension in a water-immiscible liquid to 30.degree.-100.degree. C under stirring to form spherical droplets and solidify them and in the subsequent acidic decomposition of the solid xanthate globules either directly by addition of an acid soluble in the dispersion medium, or additionally after isolation and eventual washing of the particles to achieve the required wet volume. Liquids with the viscosity up to 100 cSt are advantageously used as dispersion medium and surfactants and/or modifying reagents (e.g. epichlorohydrine) may be added to the suspension.
