BACKGROUND Many patients who require endoscopic treatments such as biopsy and polypectomy are given antiplatelet agents reluctantly. We have studied the effects of aspirin on colonic mucosal hemostasis. METHODS AND PATIENTS We developed a new endoscopic device to make a standard incision (7-mm length) on the colonic mucosa to study colon bleeding time. We(More)
A 37-year-old woman was given a diagnosis of cervical cancer in August 1994. Because of severe thrombocytopenia, she was given radiation therapy at 50 Gy with great effectiveness. The thrombocytopenia was diagnosed as idiopathic thrombocytopenic purpura. Because the patient refused to undergo a splenectomy operation, she was treated with prednisolone,(More)
INTRODUCTION [(11)C]ABP688 is a promising positron emission tomography (PET) ligand for imaging of metabotropic glutamate receptor subtype 5 (mGlu5 receptor). Of the two geometric isomers of ABP688, (E)-ABP688 has a greater affinity towards mGlu5 receptors than (Z)-ABP688. Therefore, a high ratio of E-isomer is required when using [(11)C]ABP688 as a PET(More)
A role of factor XIII (FXIII) on the interaction of human platelets with collagen was investigated using either formaldehyde fixed-washed platelets (FWP) or nonfixed platelets. The adhesion of FWP to bovine type I collagen was measured by using either an aggregometer or a collagen immobilized glass beads column. The interaction of non-fixed human platelets(More)
We compared the usefulness of blood measurements of 1,5-anhydroglucitol (1,5-AG), fructosamine and blood haemoglobin A1c (HbA1c) levels in C57BL/KsJ mice with abnormal glucose metabolism and in controls. Both streptozotocin (STZ)-induced diabetic mice (db/m genotype) and genetically diabetic mice (db/db genotype) displaying a hyperglycaemia, plasma 1,5-AG(More)
During 1990 to 1993, five patients who had been treated in our hospital for aplastic anemia (AA) with a normal karyotype, were found to have hypoplastic myelodysplastic syndromes (hMDS); three patients with RA, one RAEB, and one RAEB-T, and all of them have chromosomal abnormalities. The mean age of the hMDS patients (4 men, 1 woman) was 51.0 years (range(More)
A 63-year-old woman was diagnosed as having blue rubber bleb nevus syndrome (BRBNS) with disseminated intravascular coagulation (DIC). Hematological data showed typical DIC: PT 13.2 sec, activated PTT 55.3 sec, fibrinogen 20 mg/100 ml, FDP-E 928 ng/ml, D-dimer 3,477 ng/ml, platelet count 25 x 10(3)/microliters. Although hypofibrinogenemia was successfully(More)
A 60-year-old hemophiliac man complaining of abdominal discomfort was admitted on suspicion of hepatocellular carcinoma (HCC) by ultrasonography (US). When he was 22-year-old, blood transfusion was given for intra-abdominal hematoma due to an external wound and a diagnosis of moderate hemophilia A and non-A non-B type chronic hepatitis (later, C type(More)
We present a case report of a 55-year-old male patient with hypoplastic myelodysplastic syndrome (MDS, refractory anemia) in which a good response to recombinant human erythropoietin (rhEPO) has been maintained for more than 60 months. There is with no evidence of progression to high risk MDS or acute leukemia, although he was predicted to be a(More)
