The clinical features of 24 patients with non-specific interstitial pneumonia (NIP) were evaluated. The patients consisted of seven men and 17 women, with a median age of 60 years. In seven patients, the disease was idiopathic and eight had collagen vascular diseases. Cough, dyspnoea and fever were frequently observed. The time interval between the onset of(More)
This study was designed to evaluate the distribution of lymphocyte subsets in lung specimens that were obtained by open-lung biopsy from 8 patients with idiopathic nonspecific interstitial pneumonia/fibrosis (NSIP) and 10 patients with pulmonary fibrosis associated with collagen vascular disorders (PF-CVD). Distributions of B lymphocytes, CD4-positive T(More)
IgG4-related disease is a recently proposed clinical entity with several unique clinicopathological features. Ocular adnexal IgG4-related disease, however, has not well been clarified. The purpose of the present study was to examine 21 patients (10 men, 11 women; age range, 39-86 years) with ocular adnexal IgG4-related disease. In 17 out of 21 patients(More)
We examined the biologic properties of a small-cell-lung-carcinoma (SCLC) cell line (designated MN-1112) established from a patient with SCLC who showed paraneoplastic retinopathy syndrome. Morphologic and immunocytochemical analyses showed that MN-1112 cells possess features of the classic type of SCLC. MN-1112 cells grew in suspension forming relatively(More)
BACKGROUND It has been suggested that the humoral immune system plays a role in the pathogenesis of cryptogenic fibrosing alveolitis (CFA). Although circulating autoantibodies to lung protein(s) have been suggested, none of the lung proteins have been characterised. The purpose of this study was to determine the antigen to which the serum from patients with(More)
This study was designed to evaluate the distribution of lymphocyte subsets in lung specimens obtained by surgical lung biopsy from 12 patients with interstitial pneumonia associated with untreated polymyositis/dermatomyositis (PM/DM). Differences of histological findings and distributions of lymphocyte subsets between PM and DM were also evaluated.(More)
CD95 (Fas antigen/APO-1) is up-regulated in activated lymphocytes, and monoclonal antibody (mAb) to CD95 induces apoptosis. HLA class II molecules play a key role in antigen presentation, ligation of which induces signal transduction. We examined 18 lymphoid cell lines (15 B cell and 3 T cell lines) to investigate the effects of ligation of HLA class II(More)
The pathologic patterns of lung involvement were evaluated in 16 patients with rheumatoid arthritis (RA). They consisted of six females and ten males, with a median age of 67.5 years and diagnosed according to the American Rheumatism Association revised criteria. High-resolution computed tomography (HRCT) of the lungs was performed in all patients, and(More)
It has been argued whether bronchiectasis is truly caused by MAC infection or just a predisposed condition in which MAC colonizes. Our present study was designed to evaluate the pathological findings of bronchiectases caused by Mycobacterium avium intracellulare complex (MAC) lung infection and to demonstrate MAC in the lesion of bronchiectases. A(More)
In 2011 a 76 year-old man with a medical history of diabetes, hypertension and autoimmune pancreatitis was admitted to our hospital because of anorexia, general malaise and repeated hypoglycemia. When he was 72 years old, he suffered from pancreatitis, and pancreas head tumor was operated. IgG4-related pancreatitis was diagnosed histopathologically. On(More)
