Tay-Sachs and Sandhoff diseases are clinically similar neurodegenerative disorders. These two sphingolipidoses are characterized by a heritable absence of beta-hexosaminidase A resulting in defective GM2 ganglioside degradation. Through disruption of the Hexa and Hexb genes in embryonic stem cells, we have established mouse models corresponding to each(More)
PURPOSE We analyzed the clinical outcome of treatment with the expandable metallic stent (EMS) for the superior vena cava (SVC) syndrome associated with malignant tumors, and the results were compared with those of radiotherapy. MATERIAL AND METHODS Of 33 patients with the SVC syndrome, 23 were treated by Gianturco EMS placement and 10 were treated by(More)
Nitric oxide (NO) has emerged as an intracellular and intercellular messenger in a number of biological systems. In the present study, we demonstrated that NO was produced by cultured rat Leydig cells, and that inducible nitric oxide synthase (iNOS) messenger RNA (mRNA) was expressed in Leydig cells. NO was measured as nitrite with the method of Griess.(More)
OBJECTIVE To examine the clinical characteristics of intractable diarrhoea associated with secondary amyloidosis in rheumatoid arthritis (RA). METHODS Of 179 RA patients with biopsy confirmed secondary amyloidosis, 24 cases (23 women and one man) with intractable diarrhoea lasting for more than one month were retrospectively evaluated. RESULTS The mean(More)
Experimental autoimmune encephalomyelitis (EAE) is an inflammatory disease of the central nervous system (CNS). We previously reported upregulation of gene expression for a number of proinflammatory cytokines, interleukin-1beta (IL-1beta), IL-2, IL-6, tumor necrosis factor-alpha (TNF-alpha), TNF-beta, and interferon-gamma (IFN-gamma), in the CNS of mice(More)
We previously observed Th1-dominated response in the central nervous system (CNS) of mice during the course of experimental allergic encephalomyelitis (EAE) with a semiquantitative reverse transcriptase-polymerase chain reaction (RT/PCR) analysis. We report here that mRNA levels for both inflammatory cytokines including interleukin (IL)-1beta, IL-2, IL-6,(More)
Previously we reported the development of a highly sensitive enzyme-linked immunosorbent assay specific for anti-tuberculous glycolipid (anti-TBGL) for the rapid serodiagnosis of tuberculosis. In this study, the usefulness of an anti-TBGL antibody assay kit for rapid serodiagnosis was evaluated in a controlled multicenter study. Antibody titers in sera from(More)
Upper gastrointestinal endoscopy was performed in patients with rheumatoid arthritis (RA) during the period 1989-1991, and biopsy specimens were obtained from the stomach and from the duodenum for examining amyloid deposits. Among 407 patients, gastrointestinal amyloidosis was confirmed in 54 (13.3%). Twenty-two patients were regarded as having slight(More)
Pathophysiological mechanisms for vasospasm after subarachnoid haemorrhage (SAH) remain unclear and, so far, roles of cytokines in vasospasm have not been known. In the present study, we measured interleukin-1 alpha (IL-1 alpha), interleukin-1 beta (IL-1 beta), interleukin-6 (IL-6), interleukin-8 (IL-8), and tumour necrosis factor-alpha (TNF-alpha)(More)
BACKGROUND Intimal lesions observed in the coronary arteries (CAs) of patients who have suffered episodes of Kawasaki disease (KD) raise concern about the premature development of arteriosclerosis. Accordingly, we investigated endothelial function in the epicardial and resistance CAs after KD during long-term observation. METHODS AND RESULTS We assessed(More)
