Abstract: A method for preparing a composition for external treatment of wounds includes charging at least 90% of the oxygen binding sites of hemoglobin with carbon monoxide during or after isolation from its natural environment. The method further includes adding at least one further ingredient selected from the group consisting of electrolyte(s), preservative(s), stabilizer(s), anti-flocculant(s), anticoagulant(s), pH buffering agent(s), solvent(s), antioxidant(s), film-forming agent(s) and crosslinking agent(s). The method can further include packaging the composition, such as in an aerosol can.

Abstract: According to the claims, the present invention comprises the preparation of chemically modified, cross-linked hemoglobins with improved functional properties, the cross-linked hemoglobins prepared according to this method and the use of these hemoglobins as artificial oxygen carriers. The synthesis method is characterized by technical simplicity as well as by high yields. Deoxygenated hemoglobin of high purity is conjugated covalently under the protection of an antioxidant with an effector of oxygen binding, especially with pyridoxal-5-phosphate, after which the hemoglobin is polymerized with glutardialdehyde as a bifunctional cross-linking agent. At the same time, there is a large increase in the volume of the reaction mixture and a decrease in the concentration of the hemoglobin during the addition of the cross-linking agent. Subsequently, after further dilution with water, a polyethylene oxide derivative is chemically linked to the cross-linked hemoglobins.

Abstract: The invention relates to a method for the long-term stable and well-reproducible spectrometric measurement of the concentrations of components of aqueous solutions, especially of dialysates of interstitial tissue fluids, especially the glucose concentration. The inventive method comprises splitting a measuring beam into two partial beams by means of a beam splitter (2), and guiding one partial beam through a measuring cuvette (3), that is separated from the solution to be measured for example by a diaphragm, or that is connected to a pump system with an exchange path that is separated from the solution to be measured by a diaphragm. The other partial beam is guided through a reference cuvette (4) that is filled with a reference solution. The light intensity of both partial beams is measured and the measured signals are subjected to a symmetrical signal processing, optionally after suitable amplification.

Abstract: In a process or device for very accurate determination of the plane of polarization of polarized light, the light from a light source (1) is polarized by means of a polarizing filter (2) which has a certain setting angle &thgr;0 with respect to the first reference plane, the plane of incidence on the reflecting surface (4). The polarized beam (12) passes through the sample in the measurement chamber (3), in which the angle of rotation is changed by the small angle &thgr;MG. The sum of &thgr;0 and &thgr;MG gives the angle of rotation &thgr;e , at which the beam (13) emerging from the measurement chamber is partially reflected at the surface of a medium of higher refractive index (4).

Abstract: Artificial oxygen carrier composed of native or modified hemoglobins for direct biological or medical use, in which the oxygen binding site of the hemoglobin is provided with a protective ligand, preferably carbon monoxide, which does not have to be removed prior to use.
