Aminosäuren, z. B. Glycin, offenbar sehr günstig auf eine Diffusion aus dem Kunststoff aus. Das gute Diffusionsvermögen
ermöglicht nach einem anfänglichen
Konzentrationsabfall eine nahezu konstante Freigabe,
die über einen außerordentlich langen Zeitraum nur 55
langsam abnimmt Damit ist auch noch nach Monaten
ein ausreichender Schutz gewährleistet Das ist ein großer Vorteil gegenüber den bisher üblichen Knochenzementen
und Implantaten bei denen die freigesetzte Antibioticamenge mehr oder weniger stark schwankte. Au- 60
ßerdem sind durch die Art des Zusatzstoffes Zellschädigungen im Gewebe ausgeschlossen. Weder der Vorgang

Even before curing, the release of gentamycin obtained is achieved from synthetic resin paste for fastening endoprostheses in the usual way based on polymethacrylates and / or polyacrylics. The very good water solubility of this antibiotic is particularly effective in the presence of so
Amino acids, e.g. B. glycine, apparently very favorable to a diffusion from the plastic. The good diffusivity allows after an initial
Concentration drop an almost constant release,

Sufficient protection is guaranteed. This is a great advantage over the previously common bone cements and implants in which the amount of antibiotics released fluctuated more or less strongly. Au- 60
In addition, the type of additive prevents cell damage in the tissue. Neither the polymerisation process nor the physical properties of the plastic material are intended to affect its effectiveness
