A 50-year-old man was admitted to our hospital for the evaluation of a blunted left costophrenic angle on chest roentgenograms. Chest non-enhanced computed tomographic (CT) scans demonstrated the omentum as a crescent-shaped, fat-dense, mass-like shadow on the left dorsal thoracic wall, contiguous with the abdominal cavity and floating. Omental vessels were(More)
To observe possible changes in adrenal function during asthmatic attacks due to allergen inhalation, plasma cortisol levels were measured serially in asthmatic patients who showed immediate asthmatic responses, late asthmatic responses, and dual asthmatic responses were compared with their diurnal levels. There were slightly different patterns of cortisol(More)
Meso- and dl-1,2-diarylethylenediamines (14 species) were evaluated for pre-column fluorescence derivatization reagents in the high-performance liquid chromatographic determination of catecholamines (norepinephrine, epinephrine and dopamine) in human urine and plasma. Of the compounds, meso-1,2-bis(4-methoxyphenyl)ethylenediamine was most preferable for all(More)
Hypersensitivity pneumonitis due to the inhalation of Shiitake mushroom spores was demonstrated in a 38-year-old woman. Symptoms of cough, nausea and malaise, and clinical findings of cyanosis, bibasilar crackles, reduced lung volumes, hypoxemia, leukocytosis, elevated ESR, positive C-reactive protein, and bilateral diffuse reticulonodular shadows on chest(More)
A simple and highly sensitive method for the determination of free and total (free + conjugated) catecholamines (norepinephrine, epinephrine and dopamine) in human urine is described which employs HPLC with fluorescence detection. Conjugated catecholamines (sulfate form) are hydrolyzed by a sulfatase-mediated reaction to the corresponding free amines. After(More)
A 66-year-old man was admitted to our hospital because of bloody sputum. Chest computed tomographic scans disclosed a right hilar tumor. A tumor in the right upper-lobe bronchus was detected by fiberoptic bronchoscopy. Microscopic examination disclosed moderately differentiated squamous cell carcinoma. The patient was treated with irradiation and(More)
A curious inhibitory effect of histamine H-1 and H-2 antagonists on isolated late asthmatic response (LAR) in an asthmatic patient was observed. When given alone, neither the H-1 nor the H-2 antagonist had an effect on LAR. The combination of drugs, however, provided marked inhibition of LAR. These findings suggest that histamine contributes to some types(More)
