Abstract: The present invention is directed to a method for removing cytokines and/or pathogens from blood or blood serum (blood) by contacting the blood with a solid, essentially non microporous substrate which has been surface treated with heparin, heparan sulfate and/or other molecules or chemical groups (the adsorbent media or media) having a binding affinity for the cytokine or pathogen(s) to be removed (the adsorbates), and wherein the size of the interstitial channels within said media is balanced with the amount of media surface area and the surface concentration of binding sites on the media in order to provide adequate adsorptive capacity while also allowing relatively high flow rates of blood through the adsorbent media.

Abstract: The invention relates to a method for promoting the healing of dermal wounds by applying a composition containing chitosan and the polysaccharide, heparin or heparan sulfate. Heparin or heparan sulfate can be immobilized to chitosan by ionic or covalent bonds, and the degree of N-acetylation of chitosan can range from 25% to 90%. The composition can include a cellulose derivative as an additional polysaccharide to increase the viscosity of the composition. The combination of chitosan and polysaccharide, when applied to a wound site, effectively stimulates and accelerates wound healing.
