Using complement immunofluorescence, the capability of complement fixation by bound antibodies in pemphigus lesional skin was compared with circulating intercellular antibodies of complement-fixing type in the same patient. Five lesional skin samples from 6 patients, containing bound IgG, gave positive binding of complement (C3) supplied from fresh guinea(More)
The binding sites of Concanavalin A (Con A) and pemphigus antibody in the intercellular spaces of the human epidermis have been investigated. Extraction of human skin with phosphate-buffered saline (PBS) and 70% ethanol resulted in complete loss of the binding sites of the pemphigus antibody, whereas the extracted skin still retained its reactivity to Con(More)
A 46-yr-old man with cirrhosis presented with mental confusion, headache, and nausea. Colloid liver scintigraphy showed a defect in the hilar area, and portograms after superior mesenteric arteriography demonstrated varicose veins in the same area. Computed tomography revealed a sausage-shaped low-density channel connecting the hepatic hilum and the(More)
An attempt was made to develop an animal model for the study of the etiology of noncirrhotic portal fibrosis or idiopathic portal hypertension based on the assumption that it is related to chronic abdominal infection. Rabbits were given killed nonpathogenic Escherichia coli intraportally or intravenously. The animals to which a mixture of killed E. coli and(More)
The serum of a patient with a typical case of pemphigus vulgaria contained complement-fixing intercellular autoantibodies (pemphigus antibodies). Complement-fixing pemphigus antibodies were demonstrated only during the untreated active stage of the disease and titrated lower than corresponding IgG autoantibodies, which paralleled well with the disease(More)
To elucidate the mechanism by which propranolol reportedly affects portal hemodynamics, we investigated the effect of propranolol on systemic and splanchnic hemodynamics in 15 patients with portal hypertension and esophageal varices by simultaneous catheterization of the portal vein and the right hepatic vein and measurement of portal venous flow using an(More)
Inorder to study the relationship between epidermal surface saccharides and pemphigus antigen(s), fluorescein-labelled Concanavalin A (Con A) and Phytohemagglutinin-P (PHA-P) were used. These phytohemagglutinins were found to bind with the intercellular areas of human epidermis. Alpha-methyl-D-mannoside and alpha-methyl-D-glucoside inhibited the epidermal(More)
To evaluate the effects of anaerobic conditions and inducers for the mixed-function oxidase system on the metabolism of mitomycin C, a bioreductive alkylating agent widely used for the treatment of hepatocellular carcinoma, experiments so designed were performed in rats and mice. Metabolism of mitomycin C by microsomes from normal rat liver and(More)
