OBJECTIVES To investigate the efficacy of levofloxacin in the prevention of vascular prosthetic graft infection in a rat model. METHODS Graft infections were established in the subcutaneous tissue of 225 male Wistar rats by implantation of Dacron prostheses followed by topical inoculation with methicillin-susceptible and methicillin-resistant S.(More)
OBJECTIVE To assess the prognostic value of the APACHE II score and the American Society of Anesthesiologists (ASA) classification system in preoperative evaluation of patients. DESIGN Prospective study. SETTING University hospital, Italy. SUBJECTS 187 consecutive patients undergoing elective or emergency major general surgical operations. (More)
A rat model was used to investigate the efficacy of two polycationic peptides, ranalexin and buforin II, in the prevention of vascular prosthetic graft infection due to methicillin-resistant Staphylococcus epidermidis with intermediate resistance to glycopeptides. The in vitro activity of the peptides was compared with those of vancomycin and teicoplanin by(More)
A case of post-traumatic aneurysm of a jejunal branch of the superior mesenteric artery in a patient with Marfan's syndrome is reported. Ascending aortic involvement is well known in Marfan's syndrome but no association with visceral artery aneurysms has been previously described. The blunt abdominal trauma preceding the detection of the aneurysm may have(More)
A rat model was used to investigate the efficacy of mupirocin in the prevention of vascular prosthetic graft infection due to Staphylococcus epidermidis strains with different susceptibility patterns (methicillin susceptible, methicillin resistant, and with intermediate resistance to vancomycin). The effect of mupirocin-soaked Dacron was compared to that of(More)
BACKGROUND Liver ischemia/reperfusion is frequently associated with organ injury to which reactive oxygen species contribute. The aim of our study was to evaluate cytosolic and mitochondrial glutathione levels and morphological changes in hepatocytes of rat liver in an experimental model of ischemia/reperfusion. MATERIALS AND METHODS The experimental(More)
A rat model was used to investigate the efficacy of mupirocin in the prevention of vascular prosthetic graft infections. The effect of mupirocin-soaked Dacron was compared with the effect of rifampin-soaked, collagen-sealed Dacron in the rat model of graft infection caused by methicillin-susceptible Staphylococcus aureus and methicillin-resistant S. aureus.(More)
Several polycationic peptides isolated from animals, plants, and bacterial species possess a broad spectrum of antimicrobial activity. A rat model was used to investigate the efficacies of two peptides, ranalexin and buforin II, in the prevention of vascular prosthetic graft infections. The effect of peptide-soaked collagen-sealed Dacron was compared to(More)
