Pulse-spray thrombolysis (PST) was performed to treat large coronary thrombus in 3 patients in critical situations. The originally developed pump system and a custom infusion catheter (SciMed/Boston Scientific, Maple Grove, MN) were used in combination. Case 1, a 48-yr-old male with extensive anterior myocardial infarction, failed to be recanalized by systemic thrombolysis.

Excessive enterogastric reflux following partial gastrectomy is believed to be responsible for the cause of inflammation in the gastric remnant. We examined the effect of FUT-187, a synthetic serine protease inhibitor, on symptoms and endoscopic findings in 33 patients who were diagnosed endoscopically as postgastrectomy gastritis. Patients took 50 mg FUT-187 orally after each meal and at bedtime for 8 weeks.

During an observation period of 1-2 years in 2 different districts in Japan, 104 patients were found to have upper respiratory infections caused by group A streptococci. Fourty-nine of these patients were followed prospectively to determine if renal involvement would occur. Twelve patients developed transient serum complement (CH50) depression and urinary abnormality, and 2 of these developed mild hypertension.

Unlabelled: The mechanism of cure in AV nodal reentrant tachycardia (AVNRT) by catheter ablation has not been fully clarified. We hypothesized that disruption of a shortcut link between the fast and slow pathways is responsible for the elimination of tachycardia.

Results: AVNRT was eliminated in 20 patients by catheter ablation.

A method is described for isolating a DNA segment of a virus for which no protein or DNA sequence information is available. This segment can then be used to develop a PCR-based assay for the virus. The method is based on the widespread presence and strong conservation of the ribonucleotide reductase gene among DNA viruses.

We report the clinical results and efficacy of laparoscopic pelvic lymphadenectomy for localized prostate cancer. This procedure was followed by radical prostatectomy, when metastasis was not found in the frozen section, and by optional treatment, such as transurethral resection (TUR) or castration, other than radical prostatectomy when metastasized nodes were found. We performed transperitoneal laparoscopic lymphadenectomy on 30 patients and extraperitoneal approach on 20 between April, 1992 and September, 1995.

We have tested whether immunity can be transferred from a mother fish to its fry. Rainbow trout mother fish were inoculated against infectious haematopoietic necrosis virus (IHNV) by intraperitoneal injection of a fragment of the IHNV glycoprotein spanning amino acids 31 to 310. This protein fragment was obtained by isolating the specific cDNA from Japanese IHNV strain HV7601 and expressing it in Escherichia coli.

We report a rare case of alpha-fetoprotein (AFP), carcinoembryonic antigen (CEA), and carbohydrate antigen (CA) 19-9-producing gallbladder cancer with high levels of CA125 and protein induced by vitamin K absence or antagonist II (PIVKA II). A 63-year-old man was diagnosed with gallbladder cancer with metastases to the liver, based on ultrasonography and computed tomography of the abdomen showing multiple tumorous lesions in the liver and a thickened gallbladder wall. Laboratory data showed high levels of tumor markers: 4647.

The fully developed periodic laminar flow of incompressible Newtonian fluids through a pipe of circular cross section, which is coiled in a circle, was simulated numerically. The flow patterns are characterized by three parameters: the Womersley number Wo, the Dean number De, and the amplitude ratio beta. The effect of these parameters on the flow was studied in the range 2.

Between April 1993 and August 1995, a Hautmann's ileal neobladder was created in 37 men after total cystectomy for bladder cancer. Ureteroileostomy was performed using a submucosal tunnel instead of the Le-Duc Camey procedure. There was no operative mortality and only a few early complications.

Unlabelled: Dual-isotope scintigraphic studies with 201Tl and radioiodinated metaiodobenzylguanidine (MIBG) suggest that acute myocardial infarction causes extensive regional myocardial denervation beyond the infarcted area. We therefore investigated the histopathological and biochemical significance of the discrepancy between 201Tl and 125I-MIBG distribution determined by dual-tracer autoradiography in experimental myocardial infarction.

Methods: Left coronary arteries of 12 male Wistar rats were ligated for 30 min followed by reperfusion.

The fibrinolytic system is impaired in patients with acute myocardial infarction (AMI). The primary regulatory element of fibrinolytic activity is plasminogen activator inhibitor (PAI). There are no reports, however, on the serial changes of PAI activity after thrombolysis or coronary angioplasty in patients with AMI undergoing emergency coronary angiography.

This study was performed to investigate the role of cell-mediated immunity in lupus nephritis (LN). Frozen sections from 38 patients with LN were examined by indirect immunoalkaline-phosphatase labeling using monoclonal antibodies to identify the immune cells infiltrating into the interstitium and glomerulus. 14 patients showed minor glomerular abnormality (MGA), 9 had mesangial LN (MesLN), 12 had diffuse proliferative LN (DPLN) and 3 had membranous LN (MLN).

Coronary recanalization rate and infarct size were compared between 2 different methods of intravenously administering recombinant tissue-type plasminogen activator (rt-PA) 41.4 mg; 1) an initial bolus dose of 30% followed by infusion of the remainder over 60 min (30% group), and an initial bolus dose of 10% followed by infusion of the remainder over 60 min (10% group). Thirty min after beginning rt-PA infusion, the coronary recanalization rate was higher in the 30% group than in the 10% group (82.

Donor cards are a simple and effective way to give a consent to organ donation in cases of unexpected death. In Japan the prevalence of donor cards is low (0.4%) compared to the United States (24.

A 76-year-old man visited our clinic with chest radiographic evidence of a coin lesion in the right middle lung. Chest CT demonstrated an infiltrative shadow mainly in the S4 segment. Lymphoproliferative disorders were suggested by transbronchial lung biopsy.

The possible role of a streptococcal protein, preabsorbing antigen (PA-Ag), in human cellular immunity was examined by a lymphocyte stimulation test. Lymphocytes were obtained from 12 healthy adult donors who had no history of acute poststreptococcal glomerulonephritis nor of other renal diseases, and from the blood of 4 umbilical cords. In addition to PA-Ag, pre-purified material from ruptured cell supernatant (RCS) was also tested for lymphocyte stimulation, and their time-response relationships were compared to those with stimulation by phytohemagglutinin (PHA), a nonspecific mitogen.
