Antibiotics are often administrated prophylactically in spinal procedures to reduce the risk of infection of the disc space. It is still not known which antibiotics are able to penetrate the intervertebral disc effectively. In a prospective, randomised, double-blind clinical study, we examined the penetration of the intervertebral discs of two commonly used antibiotics, cefuroxime and gentamici...

Sparfloxacin and clinafloxacin alone and in combination with gentamicin, were evaluated for the treatment of experimental endocarditis in rabbits caused by ampicillin-resistant enterococci. Clinafloxacin was tested against Enterococcus faecalis strain WH245, a beta-lactamase producer lacking high-level gentamicin resistance (MIC 12.5 mg/L). Sparfloxacin was tested against Enterococcus faecium s...

In the last several years, a promising new approach has been suggested in the therapy of Ménière's disease (MD): the low-dose intratympanic gentamicin therapy. By titrating the desired vestibular inhibition by single injections and infrequent administration, side effects concerning hearing can be held on an acceptably low level, while disease-related symptoms are often successfully eliminated. ...

Substitution of bones is a well-established, necessary procedure to treat bone defects in trauma and orthopedic surgeries. For prevention or treatment of perioperative infection, the implantation of resorbable bone substitute materials carrying antibiotics is a necessary treatment. In this study, we investigated the newly formulated calcium-based resorbable bone substitute materials containing ...

Gentamicin was successfully incorporated into neutral, anionic, and cationic liposomes, and the percentage of gentamicin incorporated was found to be a function of lipid concentration. Gentamicin did not leak out of the liposomes over a 3-week period at 4 degrees C. When liposome-associated gentamicin was administered intravenously to rabbits, its serum half-life was greatly prolonged. Intragas...

Gentamicin continues to be a primary antibiotic against gram-negative infections. Unfortunately, associated nephro- and ototoxicity limit its use. Our previous mammalian studies showed that gentamicin is trafficked to the endoplasmic reticulum in a retrograde manner and subsequently released into the cytosol. To better dissect the mechanism through which gentamicin induces toxicity, we have cho...

Thirty-four recent clinical isolates of Streptococcus faecalis were tested for sensitivity to amoxycillin, benzylpenicillin, streptomycin, kanamycin, gentamicin, tobramycin, and amikacin. Amoxycillin was two- to four-fold more active than benzylpenicillin and all strains were inhibited by low concentrations of the penicillins. The aminoglycosides were less active against the enterococci than we...

INTRODUCTION Diabetic foot infections are frequently polymicrobial. The lower tissue concentration of systemically administered antibiotics in diabetic patients was reported. Collatamp(®)EG (Syntacoll GmbH Saal/Donau, Germany) is a bioabsorbable, gentamicin impregnated collagen spongeused for local treatment. The aim of this randomized trial was to assess influence of gentamicin-collagen sponge...

This study was designed to evaluate the protective effect of nebivolol, beta-1 blocker, on the nephrotoxicity induced by gentamicin in male albino rats. The protective effect of silymarin, as natural antioxidant, and acetylcystein, as nephroprotective agent were compared. The results revealed that three weeks of nebivolol administration prior to gentamicin, protected the rats from the oxidative...

The use of gentamicin for the treatment of bacterial infection has always been an interesting and highly speculated issue for the scientific community. Conversely, its effect on cancer cells has been very little investigated. We studied the effect of high doses of gentamicin on non-Hodgkin's T-cell human lymphoblastic lymphoma (SUP-T1). We showed that gentamicin delayed cell growth and induced ...
