BACKGROUND Sclerosing pancreatitis is a unique form of pancreatitis that is characterized by irregular narrowing of the main pancreatic duct, lymphoplasmacytic inflammation of the pancreas, and hypergammaglobulinemia and that responds to glucocorticoid treatment. Preliminary studies suggested that serum IgG4 concentrations are elevated in this disease but(More)
We report a case demonstrating the progressive narrowing of the pancreatic duct, which is presumed to be characteristic of autoimmune pancreatitis, and we review the 37 cases of chronic pancreatitis in which autoimmunity was suggested as an etiological factor in the Japanese literature. A 55-year-old man presented with abdominal discomfort, jaundice, and(More)
In an attempt to clarify the involvement of fatty acid desaturases (FADs) in the freezing tolerance of Chlorella vulgaris IAM C-27, developed by hardening, we have isolated cDNA clones for two types of FADs from the Chlorella strain, based on the sequence information of genes for delta12 and omega-3 FADs, respectively desaturating oleic acid (18:1) to(More)
CA242 has been proved to be useful in the diagnosis of pancreatic cancer. The aim of the present study was to clarify the mechanisms contributing to the high specificity of CA242 as compared with CA19-9 resulting from scarce serum elevation of this antigen in patients with chronic pancreatitis by correlating serum levels and endoscopic retrograde(More)
AIMS The purpose of this study was to elucidate the mechanism underlying the effects of adipose tissue-derived stem/stromal cell (ASC) transplantation on porcine pancreatic elastase-induced emphysema. MATERIALS & METHODS ASCs (2.5 × 10(6)) were transplanted into pancreatic elastase (250 U/kg)-treated rats, after which gas exchange and growth(More)
BACKGROUND & AIMS Conflicting reports have raised the question whether K-ras gene mutations in chronic pancreatitis are related to the development of pancreatic neoplasm. The aim of the present study was to clarify this issue by surveying patients with chronic pancreatitis and K-ras gene mutation over 4 years. METHODS K-ras point mutations at codon 12 in(More)
A 74-year-old woman with massive bilateral pleural effusion, which was exudative in nature, and with mononuclear cell predominance underwent a pleuroscopy. Parietal pleura were thickened and partly reddish in color. Biopsy specimens taken from the parietal pleura revealed lymphoplasmacytic inflammation with fibrosis. As her performance status rapidly(More)
AIMS Malignant transformation of Warthin's tumour (WT) is a rare event. We present two cases of mucoepidermoid carcinoma (MEC) arising in WT in the parotid gland. METHODS AND RESULTS Two cases of MEC arising in WT, which were found in 185 cases of WT of the parotid gland, were investigated by light and electron microscopy, and immunohistochemistry. Both(More)
BACKGROUND Although the pooled sensitivity of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) using a convex scanning ultrasound bronchoscope is equivalent to the gold standard of mediastinoscopy, diagnosis cannot be obtained in a small number of patients with poor cellularity. The method described was investigated with the aim(More)
