Abrégé

The present invention relates to the use of one or more natural or modified oxygen carriers, devoid of plasma or cellular membrane constituents, for the production of an agent for the external treatment of open wounds, particularly chronic wounds. Hemoglobin or myoglobin of human or animal origin are suitable as oxygen carriers. The oxygen carriers can also preferably be modified. Suitable modifications are cross-linking, reaction with polyalkylene oxides, chemically reactive or chemically non-reactive effectors, or combinations. The agent is applied to the wound area particularly by means of spraying on an aqueous solution containing the oxygen carrier(s). The oxygen carriers can be used in particularly effective manner in the case of chronic wounds resulting from tissue degeneration, particularly diabetic tissue degeneration.
