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)
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)
BACKGROUND AND OBJECTIVE Serum markers, including Krebs von den Lungen (KL-6), surfactant protein (SP)-D, SP-A and carcinoembryonic antigen (CEA), are reported to reflect autoimmune pulmonary alveolar proteinosis (APAP) disease severity. We evaluated serum CYFRA21-1 levels as a marker of APAP. METHODS In addition to KL-6, SP-D and CEA, we prospectively(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)
To elucidate the pathophysiology of pulmonary fibrosis, we investigated the involvement of p38 mitogen-activated protein kinase (MAPK), which is one of the major signal transduction pathways of proinflammatory cytokines, in a murine model of bleomycin-induced lung fibrosis. p38 MAPK and its substrate, activating transcription factor (ATF)-2, 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)
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)
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)
