Purpose: Postoperative methicillin-resistant Staphylococcus aureus (MRSA) infections are occasionally fatal. We hypothesized that nasal MRSA screening might predict the risk of postoperative MRSA infections. The aim of the current study was to elucidate the relationship between the positivity of nasal MRSA screening and postoperative MRSA infections.

[The operated case of 89 year-old patient with pleomorphic carcinoma of the lung].

A-89-year-old male patient who complained dry cough was detected lung mass of 3 cm size in diameter at the right upper lobe by CT. FDG-PET seemed to show hilar and mediastinum lymph nodes metastasis. After three weeks, the mass showed rapid growth with 5 cm diameter in size at CT.

Significant prognostic factors in patients with Stage IV gastric cancer with special reference to the curability of surgery.

Purposes: The purpose of this study was to determine an effective treatment strategy for patients with Stage IV gastric cancer.

Methods: We analyzed the significant prognostic factors in 74 patients who underwent surgery between 1989 and 2005, and were finally determined to have Stage IV gastric cancer. These patients were classified as curability A (n = 0), B (n = 29) and C (n = 45) according to the criteria outlined by Japanese Gastric cancer society.

The effect of overweight status on the short-term and 20-y outcomes after hepatic resection in patients with hepatocellular carcinoma.

Background: We aimed to evaluate the impact of body mass index (BMI) on the short- and long-term outcomes of hepatic resection in patients with hepatocellular carcinoma (HCC).

Methods: We performed 371 hepatic resections in HCC patients whom we categorized into two groups based on BMI: BMI ≥ 25 (n = 77) and BMI <25 (n = 294). We compared surgical outcomes between groups.

Role of femorofemoral crossover bypass grafting for unilateral iliac atherosclerotic disease: a comparative evaluation with anatomic bypass.

Purpose: To assess the role of femorofemoral or iliofemoral crossover bypass grafting, the early and late results of crossover bypasses were reviewed and compared with those of anatomic bypasses.

Methods: The clinical records of 164 patients with arteriosclerosis obliterans who underwent 99 crossover bypasses and 65 anatomic ones from 1982 to 2002 were retrospectively evaluated. The early and late results including operative mortality and morbidity, graft patency rate, limb salvage rate, and survival rate of the patients as well as backgrounds of the patients were compared between the two kinds of bypass procedures.

Protective effect of chronic vitamin C treatment on endothelial function of apolipoprotein E-deficient mouse carotid artery.

Endothelium-dependent relaxations are impaired in carotid artery of apolipoprotein E-deficient (apoE-/-) mice. This impairment seems to be due to increased formation of superoxide anions and inactivation of endothelial nitric oxide (NO). In the present study, we tested hypothesis that chronic treatment with vitamin C may prevent endothelial dysfunction by increasing release of NO from endothelial cells.

Inhibitory effect of recombinant iNOS gene expression on vasomotor function of canine basilar artery.

The present study was designed to determine the effect of recombinant inducible nitric oxide (NO) synthase (iNOS) gene expression on vasomotor function in cerebral arteries. Isolated canine basilar arteries were exposed ex vivo (30 min at 37 degrees C) to an adenoviral vector [10(7), 10(8), or 10(9) plaque-forming units (pfu)/ml] encoding either the iNOS gene or the beta-galactosidase reporter gene. Twenty-four hours after transduction, Western blot analysis demonstrated expression of iNOS protein only in iNOS (10(9) pfu/ml)-transduced arteries.

Expression and function of recombinant S1179D endothelial nitric oxide synthase in canine cerebral arteries.

Background And Purpose: Bovine endothelial nitric oxide synthase (eNOS) is phosphorylated directly by the protein kinase Akt at serine 1179. Mutation of this residue to the negatively charged aspartate (S1179DeNOS) increases nitric oxide (NO) production constitutively in the absence of agonist stimulus. The present study was designed to determine the effect of mutant S1179DeNOS gene expression on vasomotor function of canine cerebral arteries.

Protective vasomotor effects of in vivo recombinant endothelial nitric oxide synthase gene expression in a canine model of cerebral vasospasm.

Background And Purpose: Post-subarachnoid hemorrhage (SAH) cerebral vasospasm is a potentially devastating condition whose pathogenesis involves impaired nitric oxide (NO) bioavailability. We aimed to determine whether recombinant endothelial NO synthase (eNOS) gene expression may protect vasomotor function and prevent vasospasm in a canine experimental SAH model.

Methods: Recombinant adenoviral vectors (5x10(9) plaque-forming units/animal) encoding genes for eNOS (AdeNOS) and beta-galactosidase (AdLacZ) or vehicle were injected into the cerebrospinal fluid (CSF) of dogs on day -1 (ie, 24 hours before the first intra-CSF injection of blood on day 0).
