RATIONALE Chronic obstructive pulmonary disease (COPD) is characterized by airflow limitation caused by emphysema and/or airway narrowing. Computed tomography has been widely used to assess emphysema severity, but less attention has been paid to the assessment of airway disease using computed tomography. OBJECTIVES To obtain longitudinal images and(More)
RATIONALE Although the rate of annual decline in FEV1 is one of the most important outcome measures in chronic obstructive pulmonary disease (COPD), little is known about intersubject variability based on clinical phenotypes. OBJECTIVES To examine the intersubject variability in a 5-year observational cohort study, particularly focusing on emphysema(More)
The inflammatory chemokines interleukin-8, macrophage inflammatory protein-1alpha, and monocyte chemoattractant protein-1, are reportedly involved in the pathogenesis of chronic obstructive pulmonary disease (COPD). Although bronchiolar epithelial cells and macrophages are known to be the cellular sources, the relative contribution of each cell type remains(More)
This study aimed to investigate bronchiolar catalase expression and its relationship with smoking and/or chronic obstructive pulmonary disease (COPD) in humans and to determine the dynamic change of bronchiolar catalase expression in response to cigarette smoke in mice. Lung tissue was obtained from 36 subjects undergoing surgery for peripheral tumours,(More)
A 72-year-old man with idiopathic pulmonary upper lobe fibrosis who had been followed for a year developed a high fever and yellow sputum in July 2001. Chest radiography and chest computed tomography (CT) showed a rapidly enlarging cavity with an internal mass and infiltration in the left upper lung field. Pulmonary aspergillosis was diagnosed by(More)
Vascular endothelial growth factor (VEGF) signaling is crucial for lung structure maintenance. Although VEGF deficiency plays a role in the pathogenesis of emphysema in animals, little is known about VEGF expression levels and functions, as well as VEGF receptors, in airway epithelial cells, which are in direct contact with the environment. In this study,(More)
We report a case of lung adenocarcinoma in which cystic lesions enlarged and multiloculated over 2 years. Histological examination of the resected specimen found proliferation of nonmucinous adenocarcinoma cells along the alveolar walls, revealing bronchioloalveolar cell carcinoma type extension. In cystic lesions, particularly those not associated with(More)
BACKGROUND AND OBJECTIVE Transcutaneous blood gas-monitoring systems with miniaturized SpO(2) (peripheral blood oxygen saturation)/PCO(2) combined sensors (TOSCATM) have been widely used. There are no reports of the inter- and intra-individual variability in transcutaneous measurements of PaCO(2) (PtcCO(2)) in response to acute progressive changes in(More)
A 40-year-old man, a cattle hoof-chipper, was admitted to Hokkaido University Hospital in June 2002 for a workup of the occasional fever, cough and dyspnea that had affected him at work since March 2002. He had not smoked since January 2001. On admission, he had a marked increase in the proportion of lymphocytes (62.9%) and the CD 4/CD 8 ratio (3.0) in the(More)
