OBJECTIVE Epstein-Barr virus (EBV)-infected cells can evoke severe host immune responses, as shown in infectious mononucleosis and EBV-associated gastric carcinoma. To investigate the possible pathological role of EBV in inflammatory bowel disease (IBD), we tested for the presence of EBV in the colon in IBD patients. METHODS Surgically resected colonic(More)
BACKGROUND AND STUDY AIMS In the treatment of rectal carcinoid tumors, confusion arises in the choice between radical surgery and local endoscopic resection, since the malignancy of individual tumors differs widely. We investigated the appropriateness of using endoscopic therapy for this disease. PATIENTS AND METHODS Twenty-two patients were diagnosed(More)
We investigated the antifatigue effect of royal jelly (RJ), which had been stored at -20 degrees C from immediately after collection, in male Std ddY mice. The mice were accustomed to swimming in an adjustable-current swimming pool, then subjected to forced swimming five times during 2 wk, and the total swimming period until exhaustion was measured. They(More)
METHODS. The expression of ABH blood group carbohydrate antigens was examined histochemically in tumors and adjacent nontumorous tissues of 89 cases of human lung carcinoma in which nontumorous tissues expressed blood group carbohydrate antigens compatible with the erythrocyte blood group types. RESULTS AND CONCLUSIONS. Loss of ABH blood group antigens in(More)
Gastroduodenal involvement by Crohn's disease is relatively rare and occasionally causes pyloric stenosis, for which medical therapy may be ineffective and surgery may be required. We report on a 44-year-old man patient in whom corticosteroids had a marked effect in reducing pyloric stenosis caused by Crohn's disease. A proton-pump inhibitor was not(More)
The Japanese serow, Capricornis crispus (Bovidae, Caprinae, Rupicaprini), is parasitized by five Cercopithifilaria species: C. shohoi, recently described, and reexamined in this paper, C. multicauda n. sp., C. minuta n. sp., C. tumidicervicata n. sp., and C. bulboidea n. sp. Coinfections are frequent. The location (skin or subcutaneous regions) in the host(More)
Drug-induced hypersensitivity syndrome (DIHS), characterized by serious adverse systemic reactions in addition to skin rash, has unknown pathogenesis. Its association with human herpesvirus (HHV), mainly HHV-6, has been reported recently. A 46-year-old Japanese man is described in whom a generalized eruption developed about 1 month after taking cyanamide, a(More)
Reward-induced burst firing of dopaminergic neurons has mainly been studied in the primate midbrain. Voltammetry allows high-speed detection of dopamine release in the projection area. Although voltammetry has revealed presynaptic modulation of dopamine release in the striatum, to date, reward-induced release in awakened brains has been recorded only in(More)
The absorption, excretion, and metabolism of a single oral dose of suxibuzone, a new nonsteroidal anti-inflammatory agent, in healthy male volunteers were compared with those of phenylbutazone. After oral administration of either suxibuzone or phenylbutazone, phenylbutazone, oxyphenbutazone, and gamma-hydroxyphenylbutazone were found in the plasma;(More)
The boron doped diamond (BDD) electrode is presented as an appropriate candidate for next generation glass-free, highly stable and accurate pH sensors. The method used in this study is based on the potential change related to the hydrogen evolution reaction following a current step, which is pH dependent. Alkali cations in the solution have no influence on(More)
