Abstract: A chitosan for use in an antimicrobial treatment of a patient's tissue and a pharmaceutical composition comprising a chitosan for use in an antimicrobial treatment of a patient's tissue. A method of treating a microbial infection, the method comprising the step of administering to a patient an effective amount of a chitosan and an aqueous solution comprising chitosan. A chitosan or a pharmaceutical composition comprising a chitosan for use in an epithelial cell growth stimulating treatment of a patient's tissue. A method of stimulating the growth of epithelial cells the method comprising the step of administering to a patient or to an epithelial cells containing cell culture an effective amount of a chitosan or a pharmaceutical composition comprising chitosan. A tissue dressing material characterized in that it consists of chitosan or a chitosan comprising composition.

Abstract: Liquid compositions are used to differentially promote the growth of the microbiome. The liquid composition forms a membrane when applied to the skin of a subject. The liquid composition as well as the membrane comprise chitosan or a salt thereof with a degree of acetylation of 20% or less and at least one additional agent. Also disclosed are pharmaceutical compositions for use in the prevention or reduction of skin irritation, allergy and/or an infectious disease.

Abstract: A tissue dressing material for being applied in contact with a tissue of a patient. The tissue dressing material's main component is deacetylated native chitosan. Moreover, a liquid tissue dressing material for being applied in contact with a tissue of a patient, the tissue dressing material being an aqueous mixture. The main component of the constituent(s) of the mixture other than water is deacetylated native chitosan.

Abstract: The present invention relates to methods for disinfecting or decontaminating a material or for preventing an infection or contamination of a material. The invention further relates to compositions which are suitable for disinfecting a material or for preventing an infection or contamination of a material and to uses of such compositions. The invention further relates to a medical use of chitosan and to a pharmaceutical composition comprising the chitosan.
