Gentamicin incorporated in beads of polymethylmethacrylate has been shown capable of being released over a period of several months in concentrations sufficiently high to control most pathogens. The therapeutic efficacy of such beads has been demonstrated in a model of osteomyelitis of the femur in the dog. Good tolerance has been shown, both in the animal(More)
Inflammation results in a local increase in nerve growth factor production which potentially can modify the properties of nerve growth factor-responsive sensory neurons innervating the inflamed tissue. The sensitivity of primary sensory neurons to the neurotoxin capsaicin is regulated in vitro by nerve growth factor and we have now investigated the effect(More)
Toll-like receptors (TLR) play a key role in the recognition of pathogenic organisms. Fibronectin, an extracellular matrix protein, is considered a potent stimulator of the innate immune system through TLR4. In bacterial meningitis, several extracellular matrix proteins and bacterial compounds are elevated in the CSF. For this reason, we hypothesized that(More)
Bisoprolol, (+/-)1-(4-[(2-isopropoxyethoxy)-methyl]-phenoxy)-3-isopropyl-amino -2- propanol-hemifumarate, is a new, highly selective beta 1-adrenoceptor blocking agent without intrinsic sympathomimetic activity and low to moderate local anaesthetic activity. As demonstrated in binding experiments, and in classical pharmacological studies using rats, guinea(More)
The pharmacodynamic activity of (+/-)-1-[4-(2-isopropoxyethoxymethyl)-phenoxy]-3-isopropylamino-2- propranol- hemifumarate (bisoprolol, EMD 33 512) has been investigated under in vitro and in vivo conditions. Bisoprolol was found to be an effective beta-adrenoceptor antagonist, the pA2 values determined against isoprenaline in guinea pig atria and tracheal(More)
Gentamicin PMMA beads (PMMA = polymethylmethacrylate) represent a new form of local antibiotic therapy for treating chronic bone and soft tissue infections. Gentamicin is released in high concentrations from PMMA. The therapeutic efficacy of the beads was demonstrated in a model of bone infection in dogs. Sufficiently high tissue concentrations of(More)
The influence of metyrapone on bile flow and excretion of mono-(MBA), di-(DBA) and trihydroxy-(TBA)-bile acids was investigated in adult male Wistar rats after single and repeated pretreatment. MBA were not found in the rat bile. Metyrapone administration (200 mg/kg b.w. i.p.) 1 h before onset of a 3-hour bile collection period diminished bile flow and(More)
The pharmacologic modulation of the platelet-activating factor antagonist WEB 2086BS on the release of metabolites of the arachidonic acid and the cytokine TNF alpha was investigated in an ex vivo xenograft model of hyperacute rejection. Pig kidneys were perfused for 60 min in a perfusion system with oxygenated heparinized human or autologous porcine blood,(More)
