The present study was designed to evaluate the pathological and immunohistochemical findings of Mycobacterium avium intracellulare complex (MAC) lung infection. A retrospective study was performed in five cases with positive cultures for MAC in whom lung resections were performed between January 1989 and December 1996. A determination of whether or not MAC(More)
Effect of left ventricular (LV) volume on right ventricular (RV) end-systolic pressure-volume relation (ESPVR) was investigated, and the mechanism was examined from a standpoint of the alteration of RV free wall mean fiber length. Twelve cross-circulated isovolumically contracting canine hearts in which both ventricular volumes were controlled independently(More)
Acute and chronic alterations of right ventricular (RV) wall properties can change left ventricular (LV) performance. We investigated whether and how stiffening of the RV free wall alters LV diastolic distensibility. We used cross-circulated isolated hearts, in which the LV and RV were independently controllable. Stiffness of the RV free wall was altered by(More)
This report is concerned with twins with cystic fibrosis (CF). They are of mixed parentage: Japanese mother and German father. One case is presented with meconium ileus as a neonate. The other patient did relatively well until the age of 6 years when she was first hospitalized and diagnosed with pulmonary aspergillosis. They have been receiving standard(More)
The cause of digital clubbing is unknown. Hepatocyte growth factor (HGF) is a pleotrophic factor which has various biological effects. We measured serum HGF in 12 patients with digital clubbing; the underlying diseases of these patients were: lung cancer, 2; cystic fibrosis, 2; idiopathic pulmonary fibrosis, 3; lung cancer with idiopathic pulmonary(More)
OBJECTIVE Little is known as to whether an increase in coronary perfusion pressure can alter the right ventricular (RV) distensibility and the contractile function as it does in the case of the LV. METHODS In eight isolated isovolumically contracting canine hearts, RV and LV volumes and coronary perfusion were independently controlled. Effects of an(More)
This study was undertaken to compare axial images of 99mTc-Technegas SPECT (Technegas) with those of 133Xe gas dynamic SPECT in patients with pulmonary emphysema. There were 20 patients, 19 males and 1 female. All patients except one ex-smoker were heavy smokers with a mean age of 68.1 years. For Technegas scintigraphy, the patients inhaled 505 MBq(More)
Recently, we have experienced significant number of patients diagnosed with non-specific interstitial pneumonia (NSIP) by open lung biopsy or video-assisted thoracoscopic surgery. The purpose of this study is to compare clinical and pathological features of idiopathic NSIP and NSIP associated with underlying diseases (mainly autoimmune disorders). Forty-six(More)
An outbreak of coagulase VII-producing, arbekacin (ABK)-resistant, methicillin-resistant Staphylococcus aureus (MRSA) occurred between September 1994 and December 1995, involving five different wards. Twenty-one patients developed skin, wound, drainage, or respiratory tract colonization with coagulase VII-producing, (ABK)-resistant MRSA. Phenotypic(More)
Between January 1988 and December 1992, 68 patients admitted to our Department of Internal Medicine with haematological malignancies or solid tumours showed colonization of the respiratory tract with Stenotrophomonas maltophilia. To characterize the significance of respiratory tract colonization by S. maltophilia, we retrospectively reviewed the medical(More)
