    • A polymethylmethacrylate bone cement with a liquid monomer component and a solid component contains in the monomer liquid, for example, 0.001-1.00 mass percent of a dye or dye mixture that is insoluble or poorly soluble in methacrylic acid methylester and, for example, 0.001-2.00 mass percent of a synthetically produced, protein-free, hydrophobic, low molecular or oligomeric solubilizer for the dye or dye mixture. The solubilizer preferably is liquid or pasty at room temperature. The monomer liquid is translucent at room temperature. Preferably, 0.001-1.00 mass percent of a dye or dye mixture that is insoluble or poorly soluble in methacrylic acid methylester and, preferably, 0.001-2.00 mass percent of a synthetically produced, protein-free, hydrophobic, low molecular or oligomeric solubilizer that is liquid or pasty at room temperature are homogeneously dissolved in the polymethacrylate or polymethylacrylate of the powder component.

    • A local system for the release of active principle is described which consists of approximately spherical or rotation symmetrical bodies which are composed essentially of polymethyl methacrylate or polymethyl methacrylate co-methyl acrylate, zirconium dioxide or barium sulphate and one or more pharmaceutical active principles, in particular antibiotics, and which are produced by radical polymerization, radical polymerization activators effective in the temperature range of 10-80° C. or residues of these polymerization activators from the groups of aromatic amines, heavy metal salts and barbiturates not being contained therein.A process for the production of the local system for the release of active principle in the case of which a) a paste is produced by mixing methyl methacrylate, polymethyl methacrylate or polymethyl methacrylate co-methyl acrylate, zirconium dioxide and/or barium sulphate, one or more pharmaceutical active principles and a thermally decomposing radical initiator, the paste having a viscosity such that it cannot be deformed at room temperature by the effect of gravity; b) the paste is injection molded by an injection molding device without heating at room temperature into approximately spherical or rotation-symmetrical bodies or the approximately spherical or rotation symmetrical bodies are injection-molded onto a wire; c) the bodies are heated to a temperature at which the polymerization initiator decomposes.
