conclusions our results illustrated the presence of clonal groups of highly gentamicin-resistant strains of mrsa in hospitals in tehran. the php typing method provided useful information for both clonal dissemination and determining the epidemiological links of the clonal groups of the mrsa strains. materials and methods a total of 301 s. aureus isolates were collected during january to novembe...

objective(s): in recent years, there has been an increasing amount of study on early diagnosis of kidney injury through sensitive and specific biomarkers. we examined the practical applicability of the urinary levels of nag (n-acetyl-β-d-glucosaminidase), ap (alkaline phosphatase), and ldh (lactate dehydrogenase) as renal dysfunction screening biomarkers in full and pre-term newborns treated wi...

background and aims. enterococci are among resistant microorganisms to antibiotics and are responsible for some of acute gingival infections. this study aimed at molecular evaluation of gentamicin-resistant enterococcus species and determining the resistance genes. materials and methods. clinical samples were cultured on bhi medium and enterococci were isolated by specific methods and antibiogr...

the clinical uses of gentamicin have so far been restricted due to nephrotoxicity and ototoxicity. the exact mechanism of nephrotoxicity is still unknown; however, it appears that free radicals may be involved. methionine has previously been shown to alleviate oxidative stress involved in ototoxicity due to its antioxidant properties. therefore, the effect of methionine supplementation on the g...

To assess the effect of protein binding by human serum on the synergistic interaction of penicillins with gentamicin, time-kill curves were determined for four penicillins alone and in combination with gentamicin against 10 blood isolates of enterococci. Killing curves demonstrated synergism with penicillin G plus gentamicin against all 10 strains in either broth or 50% human serum. In broth th...

Objective(s): Gentamicin belongs to the family of aminoglycoside antibiotics and is a preferred drug in developing countries because of its low cost, availability, and potent effects against bacterial. However, gentamicin can induce nephrotoxicity. In this research, hydroalcoholic extract of Rheum turkestanicum was used against gentamicin- induced nephrotoxicity. Rheum turkestanicum is used aga...

BACKGROUND Gentamicin is often used to treat infective endocarditis (IE). Gentamicin is highly effective, but its applicability is reduced by its nephrotoxic effect. The aim of this study was to quantify the nephrotoxic effect of gentamicin and the association between the nephrotoxic effect and mortality in patients with IE. METHODS A prospective observational cohort study was performed at 2 ...

PURPOSE Gentamicin is a widely employed antibiotic, but may reduce calcium uptake by eukaryotic cells. This study was conducted to determine whether gentamicin reduces calcification by porcine aortic valvular interstitial cells (pAVICs) grown in 2D culture, which is a common model for calcific aortic valve disease (CAVD). METHODS AND RESULTS The presence of gentamicin (up to 0.2 mM) in the me...

There have been many investigations on non-biodegradable materials acting as an antibiotic carrier for local drug delivery systems based on polymethyl methacrylate (PMMA) beads. However, the material is non-degradable and non-porous so that less than 5% of the encapsulated drug is released. In order to obtain better release of the antibiotics, greater porosity of the beads would be required. Ad...

gentamicin is a bactericidal aminoglycoside antibiotic, it inhibits the protein synthesis. gentamicin is active against the majority of aerobic gram-negative bacilli such as pseudomonas, klebsiella and escherichia coli. the gentamicin doses are 3 mg/kg once-daily for preterm newborns < 35 weeks of gestation and 4 mg/kg once-daily for newborns > 35 weeks of gestation. the monitoring of gentamici...
