We have attempted to design classification criteria for adult Still's disease by analyzing the data obtained through a multicenter survey of 90 Japanese patients with this disease and of 267 control patients. The proposed criteria consisted of fever, arthralgia, typical rash, and leukocytosis as major, and sore throat, lymphadenopathy and/or splenomegaly,(More)
A comprehensive survey of Japanese patients with adult Still's disease was made by questionnaire which was sent to major institutions with rheumatology units in Japan. Of 146 cases from 32 institutions, 90 were judged to be definitely diagnosed as adult Still's disease. The major clinical features in these 90 patients consisted of high fever,(More)
Platelet agonists increase the affinity state of integrin alphaIIbbeta3, a prerequisite for fibrinogen binding and platelet aggregation. This process may be triggered by a regulatory molecule(s) that binds to the integrin cytoplasmic tails, causing a structural change in the receptor. beta3-Endonexin is a novel 111-amino acid protein that binds selectively(More)
PURPOSE The objective of this study was to determine the benefits of adjuvant radiotherapy after radical resection of locally advanced main hepatic duct carcinoma (Klatskin tumor). METHODS AND MATERIALS We conducted a retrospective review of 63 patients who underwent surgical resection of Stage IVA Klatskin tumor. Of the 63 patients, 47 had microscopic(More)
To clarify the physiological roles of CD36 as an oxidized low density lipoprotein (OxLDL) receptor, we analyzed the monocyte-derived macrophages from normal and two CD36-deficient subjects, since we identified the molecular abnormalities (Kashiwagi, H., Y. Tomiyama, Y. Kosugi, M. Shiraga, R. H. Lipsky, Y. Kanayama, Y. Kurata, and Y. Matsuzawa 1994. Blood.(More)
The glycoprotein vitronectin (also called S-protein, serum spreading factor, or epibolin) promotes spreading of a variety of cultured cells, inhibits the cytotoxicity of membrane attack complex C5b-9, and modulates thrombin-antithrombin III activity. We developed a strikingly simple method to purify vitronectin from human plasma by heparin affinity(More)
Integrins respond to "inside-out" signals, which enable them to bind adhesive ligands, and ligand binding initiates "outside-in" signals that mediate anchorage-dependent cellular responses. RhoA is a GTPase that regulates certain actin rearrangements and transcriptional events. It has also been implicated in integrin signaling, but the exact relationship is(More)
In this study, we have identified a patient (OSP-1) with a congenital P2Y12 deficiency showing a mild bleeding tendency from her childhood and examined the role of P2Y12 in platelet function. At low concentrations of agonists OSP-1 platelets showed an impaired aggregation to several kinds of stimuli, whereas at high concentrations they showed a specifically(More)
BACKGROUND The purpose of the study was to establish an animal model of chronic acid reflux esophagitis which could be used for further investigations of the pathophysiology of reflux esophagitis. METHODS Esophagitis was produced by ligating the transitional region between the forestomach and the glandular portion with a 2-0 silk thread and covering the(More)
