The influence of the polyamino acid polyaspartic acid (PAA) on experimental aminoglycoside nephrotoxicity was determined. PAA prevented all measured functional and pathologic evidence of gentamicin nephrotoxicity for less than or equal to 27 d of study. All the animals given PAA, either alone or with gentamicin, developed prominent cytoplasmic vacuoles in(More)
BACKGROUND Since the advent of universal precautions and body substance isolation, few studies have examined the relationship between glove use and handwashing. METHODS During a 5-month period in 1991, 477 structured observations were conducted on 19 patients care units at a community teaching hospital during each of three shifts. Patient care contacts(More)
PURPOSE The primary purpose of the clinical trial was to assess the safety and efficacy of once-a-day compared with three-times-a-day gentamicin in patients with serious infections who had protocol-determined peak serum aminoglycoside concentrations. PATIENTS AND METHODS A total of 249 hospitalized patients with suspected or proven serious infections were(More)
Aminoglycoside antibiotics achieve bacterial killing by binding to bacterial ribosomes and inhibiting protein synthesis. To examine whether similar mechanisms could be present in renal tubular cells prior to the onset of overt proximal tubular necrosis due to these drugs, we isolated microsomes from Fischer rats given 20 mg/kg gentamicin every 12 h(More)
Scant data exist on intracellular events during aminoglycoside-induced postantibiotic effect (PAE). We examined DNA, RNA, and protein syntheses after tobramycin exposure using [3H]thymidine, [14C]uracil, and [14C]alanine incorporation in a clinical Escherichia coli strain. Late-log-phase bacteria in oxygenated minimal salts medium at 37 degrees C were(More)
Age-matched male and female Fischer 344 rats were treated with gentamicin, 40 mg/kg of animal body weight per day, for three to 21 days. Renal dysfunction was less severe in females as measured by concentrations of blood urea nitrogen and creatinine and by cortical slice uptake of p-aminohippuric acid and N1-methylnicotinamide chloride. Also, cortical(More)
The renal handling of vancomycin is unknown. Previously reported studies have not achieved steady-state conditions with constant vancomycin concentrations. We measured systemic vancomycin clearance simultaneously with the renal clearances of vancomycin, creatinine, inulin, and para-aminohippurate in nine healthy subjects at steady-state serum vancomycin(More)
This document provides new general guidelines for the design and execution of studies evaluating anti-infective drugs for the prevention or treatment of infectious diseases. The first step in evaluation is the determination of in vitro microbial susceptibility. Next, studies are conducted in animals. Several animal models provide information useful in the(More)
