The portal vein hemodynamics of patients with various liver diseases were investigated by means of a duplex system consisting of a linear electroscanner and a pulsed Doppler flowmeter. In cases of chronic liver disease, the cross-sectional area of the portal vein trunk became greater as the liver injury proceeded, while the maximum velocity tended to(More)
During the last 8 years, the diagnosis of tuberculous colitis has been made radiologically in 22 cases. Twelve were confirmed by histological or bacteriological evidences. The X-ray findings are classified into three types as follows: Type A, showing an extensive scarred area in the ileocecum and ascending colon. Type B, showing annular stricture in the(More)
A 47-year-old woman was admitted for evaluation of pain in the right upper quadrant of the abdomen. Seventeen years previously, she had undergone cholecystectomy for cholelithiasis. Endoscopic retrograde cholangiopancreatography (ERCP) showed a cystic dilatation of the terminal portion of the common bile duct (CBD) protruding into the duodenal lumen and(More)
We have investigated the effects of dibutyrylcAMP, forskolin, carbamylcholine chloride (carbachol),ionomycin, and 12-O-tetradecanoylphorbol-13-acetate(TPA) on the expression of guinea pig pepsinogen mRNA in monolayer cultured gastric chief cells.After exposure of the cells to each of these compoundsfor 4 to 24 hr, and at 48 hr after primary culture,total(More)
Transforming growth factor (TGF)β levels are elevated in, and drive the progression of, numerous disease states such as advanced metastatic cancer and systemic and ocular fibrosis. There are 3 main isoforms, TGFβ1, 2, and 3. As multiple TGFβ isoforms are involved in disease processes, maximal therapeutic efficacy may require neutralization of 2 or more of(More)
Tonsillar tuberculosis is one of the uncommon forms of extrapulmonary tuberculosis. We report a case of tonsillar tuberculosis associated with pulmonary and laryngeal foci. A 23-year-old female was admitted for evaluation of hoarseness and difficulty in swallowing. Bilateral palatine tonsils were enlarged, and a tonsillectomy was performed. Since a(More)
A 63-year-old woman was admitted with high fever. Laboratory tests showed leukocytosis and elevated C-reactive protein (CRP) levels. Abdominal ultrasonography and computed tomography revealed multiple liver and splenic tumors. We diagnosed phlegmonous gastritis with multiple liver and splenic abscesses based on a discharge of pus from the gastric ulcer on(More)

Evaluation of endoscopic retrograde cholangiopancreatography (ERCP) and percutaneous transhepatic cholangiography (PTC) for differential diagnosis was studied in 53 patients with stenotic lesions of biliary tract in special reference with malignancy. Uhrasonography (US) and computed tomography (CT) were also studied for the comparison with ERCP and PTC. The(More)
