Protective efficacy of Actinobacillus pleuropneumoniae extracellular hemolytic toxins, RTX-toxin I (Apx I) and Apx II, was evaluated in pigs. The hemolysins were purified from culture supernatant of A. pleuropneumoniae strain HA-337, serotype 1 by immunoaffinity chromatography using a monoclonal antibody specific for Apx I or Apx II as ligand. Four pigs(More)
Multiple-antigen simultaneous test (MAST) is a new system for detecting allergen-specific IgE antibodies. Multiple antigens can be examined simultaneously in a short period of time by this method. The purpose of this study is to evaluate the usefulness of this method and to compare the results of MAST with those of RAST and intradermal skin test using 133(More)
The multiple-antigen simultaneous test (MAST) is a simple system that uses no radioactive agents and allows simultaneous examination of multiple antigens. CAP is a quick new, in vitro system that is more sensitive than the radio-allergosorbent test (RAST). To evaluate their clinical efficacies, we examined the correlation between the MAST and CAP systems.(More)
Two women aged 33 and 57 years respectively, and a man aged 40 years visited our hospital complaining of swelling of the parotid gland region. The diagnosis of eosinophilic lymphfolliculoid granuloma of the soft tissue (Kimura's disease) based on laboratory findings was made in all 3 cases. Patient 1 received radiation therapy followed by surgery, and(More)
OBJECTIVE in predictable target movements, pursuit gains are extremely close to 1.0. Under these conditions, aging effects upon pursuit have not been detected. Step-ramp stimuli produced by unpredictable combinations would be favorable procedures to assess the properties of smooth pursuit between young and aged people. METHODS the target was a 0.5 degrees(More)
In this study, 20 subjects (5 women and 15 men, 22-28 years old) were tested for vertical optokinetic nystagmus (OKN) to establish the asymmetry between up and down OKN responses in humans. The subjects were exposed to both upward and downward OKN stimulus at constant velocities of 30, 40, 50, 60, 70, 80, 90 degrees/s in the upright position. Eye movements(More)
Histamine content and enzyme activities of histamine metabolism, histidine decarboxylase (HDC), histamine N-methyltransferase (HMT) and histaminase (diamine oxidase, DAO) in human nasal mucosa were determined with a highly sensitive and specific fluorescent method which was combined with high performance liquid chromatography. Histamine content and HDC(More)
There are various theories on the causes of otitis media with effusion. The exact pathogenesis, however, still remains unknown, while the causes have been so far elucidated and studied by many researchers. This disease occurs frequently in children, showing an increasing trend, often causes subsequent deafness, and its treatment takes a long time causing(More)
OBJECTIVES Visually induced eye movements were investigated in 26 patients with Wallenberg's syndrome. METHODS Slow-phase optokinetic nystagmus (OKN) velocities, pursuit gains, and percentage fixation suppression (%FS) of caloric nystagmus were recorded by DC electrooculography (EOG), and stored directly onto FM magnetic tape. RESULTS OKN velocities,(More)
Arachidonic acid metabolites (AAMs) are known to be involved in inflammation. It is suggested that AAMs play an important role in the pathogenesis of nasal polyp. We have measured the levels of prostaglandin E2, 6-keto prostaglandin F1 alpha, thromboxane B2, leukotriene B4 and a mixture of leukotriene C4, D4 and E4 in both nasal polyp and maxillary sinus(More)
