RATIONALE Acquired pulmonary alveolar proteinosis (PAP) is a syndrome characterized by pulmonary surfactant accumulation occurring in association with granulocyte/macrophage colony-stimulating factor autoantibodies (autoimmune PAP) or as a consequence of another disease (secondary PAP). Because PAP is rare, prior reports were based on limited patient(More)
OBJECTIVE The purpose of this study was to determine whether measurements of lung attenuation at inspiration and expiration obtained from 3D lung reconstructions reflect the severity of chronic obstructive pulmonary disease. SUBJECTS AND METHODS Seventy-six patients with chronic obstructive pulmonary disease underwent MDCT with 3D postprocessing at full(More)
PURPOSE To determine whether concurrent emphysema influences the distinction between usual interstitial pneumonia (UIP) and nonspecific interstitial pneumonia (NSIP) at thin-section computed tomography (CT). MATERIALS AND METHODS Institutional review board approval was obtained for this retrospective study; informed consent was not required. The study(More)
A 38-year-old woman presented with worsening cough, blood eosinophilia, and pulmonary infiltrates. Bronchoalveolar lavage showed 96.4% eosinophils. The diagnosis of visceral larva migrans (VLM) was made based on the positive results in enzyme-linked immunosorbent assay for Toxocara canis together with clinical symptoms and laboratory data. Pulmonary(More)
Bolus-administered intracerebroventricular (ICV) relaxin-3 has been reported to increase feeding. In this study, to examine the role of relaxin-3 signaling in energy homeostasis, we studied the effects of chronically administered ICV relaxin-3 on body weight gain and locomotor activity in rats. Two groups of animals received vehicle or relaxin-3 at 600(More)
To elucidate the biological significance of selectin for idiopathic pulmonary fibrosis, we titrated the serum soluble E-selectin. From 31 cases of idiopathic pulmonary fibrosis patients without signs or symptoms of infection, the serum was obtained and the concentration was titrated by enzyme-linked immunosorbent assay. The serum soluble E-selectin titer(More)
An inflammatory cytokine, tumor necrosis factor (TNF)-α, has been implicated in the pathogenesis of inflammatory lung diseases such as interstitial pneumonia (IP). To clarify the role of the inflammatory cytokine in the pathogenesis of lung inflammation, we introduced a murine TNF-α gene into murine lungs by the hemagglutinating virus of Japan(More)
The selectin family adhesion molecules exert a crucial role in accumulation of leukocytes at the site of inflammation. To test the biological effects of soluble selectin on lung inflammation, we introduced an expression plasmid vector of soluble selectin gene via HVJ-liposome into a murine model of LPS-induced lung injury. The myeloperoxidase activity in(More)
Two thioacetate tails were introduced to the chlamydocin- and CHAP31-related cyclic tetrapeptides. An intramolecular disulfide bridge could be formed in the CHAP31-related cyclic peptides. Both the thioacetate-tailed and disulfide-bridged peptides were potent histone deacetylase inhibitors in the presence of sulfhydryl compound. Potent p21 promoter inducing(More)
RATIONALE Inhaled granulocyte/macrophage-colony stimulating factor (GM-CSF) is a promising therapy for pulmonary alveolar proteinosis (PAP) but has not been adequately studied. OBJECTIVES To evaluate safety and efficacy of inhaled GM-CSF in patients with unremitting or progressive PAP. METHODS We conducted a national, multicenter, self-controlled, phase(More)
