High-performance liquid chromatography with column switching and mass spectrometry (MS) was applied to the on-line determination and resolution of the enantiomers of E2020 (acetylcholinesterase inhibitor) in plasma. This system employs two avidin columns and fast atom bombardment (FAB)-MS. A plasma sample was injected directly into an avidin trapping column(More)
A 57-year-old woman with chronic hepatitis C was treated with alpha-2b interferon (IFN). Forty-five days after the initiation of IFN therapy, she developed cardiogenic shock. Acute perimyocarditis as a cause of cardiogenic shock was clinically suspected by the findings of complete atrioventricular block, regional wall motion abnormality and pericardial(More)
To eliminate complicated procedures for taking blood samples in the field work for prostatic mass screening, we developed a method for PSA testing using blood samples taken from the ear lobe and dried on a filter paper. The stability, the diagnostic efficacy, and the cost-benefit effect of the method were confirmed in hospitalized patients, as well as in(More)
The transradial approach (TRA) has been used for diagnostic and interventional cardiology. It has not previously been determined how many times the same radial artery can be cannulated without complications. A total of 812 patients (502 men and 310 women) underwent angiography or angioplasty via the TRA between 1997 and 1999 at our institution with a total(More)
The effect of the section or stimulation of various nerves on prostatic contraction and fluid excretion was investigated dynamically in the dog using an apparatus devised in our laboratory. Prostatic contraction could be classified into two types from the pattern of the contracting wave. One was a prominent tonic contraction, designated as H-type(More)
Sarcoidosis is characterized by multisystemic granulomatous lesions of unknown etiology. A 62-year-old woman developed sarcoidosis after treatment with alpha-2a interferon (IFN) for 24 weeks (total dose: 522 million units) for chronic hepatitis C. She developed complete atrioventricular block and multiple noncaseating granulomatous lesions in the lung. IFN(More)
Real-time scanning was applied to the sonically guided puncture technique. A special puncture attachment connected to the ultrasound sector scanner was developed for this purpose. A puncture needle is introduced into the scanning plane through the canal in the attachment. Excellent real-time images of both the target lesion and the needle can be clearly(More)
