摘要:
A bioactive PMMA (polymethylmethacrylate) bone cement contains a powder component and a reactive monomer liquid, wherein the powder component and the reactive monomer liquid when mixed with one another react with one another and form a polymer-based solid material. The powder component contains particulate polymer powder of polymethylmethacrylates; a radical starter; and anionic copolymer nanoparticles. The anionic copolymer nanoparticles are distributed in nano-particulate form within the particulate powder component or coated as a film on particles of the particulate polymer powder.

The invention relates to a structured composite as a carrier for the tissue engineering and implant material of bones, consisting of a mass of porous calcium phosphate granulates. The granulated material has a grain size of between 0.5 and 10 mm with macropores and micropores, and the macropores have an average diameter of between 50 and 500 ?m and are bound by a biocompatible binding agent.
摘要:
The invention relates to active substance combinations which consist of at least one polypeptide with the biological action of fibroblast growth factors and of at least one cationic polyelectrolyte. These combinations permit improved dosage of the FGF activity. The invention also relates to a method of treating wounds, burns, skin ulcers, diabetic gangrene, mucosal ulcers and lesions, skin donation and transplantation sites, or surgical wounds by administering a peptide having FGF activity with an amount of cationic polyelectrolyte which is effective to decrease non-specific binding of the peptide having FGF activity.
摘要:
The invention relates to the use of clindamycin palmitate for the production of pharmaceutical administration forms having a protracted release of the antibiotic active compound clindamycin, and corresponding administration forms which are preferably used in the form of shaped implants.
摘要:
A femoral prosthesis for implantation by cementation, has the stem with a longitudinal borehole extending proximally to distally for the transprosthetic application of the bone cement. The prosthesis stem is surrounded by an elastic sheath of a biocompatible polymeric material in such a way that, on application of the cement, the sheath is filled advancing distally to proximally and, when the space between stem and bone bed is completely filled, pressed flush against the bone bed.
摘要:
A device for mixing and discharging bone cement has a mixing cylinder which consists of two cylinder parts and in which an openworked mixing plunger can be moved axially. The lower cylinder part is sealed off by a discharging plunger. A separating plunger is arranged axially displaceably in the mixing cylinder between the mixing plunger and the discharging plunger, which separating plunger seals off the one cylinder part before the two cylinder parts are connected. The separating plunger has through-flow channels through which a liquid monomer can flow from the lower cylinder part to a pulverulent polymer in the upper cylinder part at the start of the mixing procedure.
