The purpose of this study was to evaluate whether the plasma brain natriuretic peptide (BNP) concentration is a useful marker of right ventricular (RV) overload and whether it has prognostic value as a predictor of death in patients with chronic respiratory disease (CRD). We measured the plasma BNP and atrial natriuretic peptide (ANP) concentrations in 31(More)
The effects of diffusion and ultrafiltration on cardiac output (CO) and organ blood flow (BF) in the uraemic dog were studied by a modified microsphere technique. In the diffusion phase of sequential therapy, a decrease in mean arterial pressure (MAP) and total peripheral resistance (TPR) was noted despite no change in circulatory plasma volume (CPV) and(More)
Fifty-six patients with locally invasive bladder cancer were treated by chemotherapy with intermittent arterial infusion from an implanted reservoir and alteration of intrapelvic blood flow. The tip of an infusion catheter was inserted selectively into an internal iliac artery by an angiographic technique. Superior gluteal artery and the other internal(More)
Polyamines (mainly putrescine, spermidine, and spermine) whose biosynthesis is a prerequisite for cell proliferation, are potential indicators of malignant growth. To investigate the mechanism of alterations of polyamine levels in physiological fluids in human cancer, polyamine levels of bone-marrow plasma from adult patients with leukemia were studied.(More)
OBJECTIVE To clarify histologic localization of estrone sulfatase in normal uterine endometrium and adenomyotic tissue and to confirm that estrone sulfatase is one of the enzymes that supplies estrogen to adenomyotic tissue. METHODS Specimens from 21 patients who had undergone hysterectomy were obtained from uteri with histopathologically proven(More)
Congenital vesicovaginal fistula is very rare and only five cases have been reported so far. This is a report on a case of congenital vesicovaginal fistula in a three-year-old girl. Vesicovaginal fistula was confirmed by cystoscopy and colposcopy. Roentgen examinations, including IVP, CG and CT revealed a left hypoplastic kidney, left ectopic ureteric(More)
Two girls (4 and 3-year old) visited our out-patient service complaining of daytime and nighttime enuresis. Both were diagnosed as ectopic ureteral opening to the vagina with a concomitant dysplastic kidney on the left side. These anomalies were repaired by ureterocystoneostomy according to a modified Grégoir's method. In the first case, three months later,(More)
BACKGROUND It has been recently suggested that cardiac troponin T (cTnT) may be more sensitive than troponin I (cTnI) for subclinical myocardial cell injury in patients on chronic dialysis. METHODS We prospectively compared the predictive value of cTnT with cTnI, atrial (ANP) and brain natriuretic peptide (BNP) in 100 consecutive outpatients on chronic(More)
Prostatic neuroendocrine (NE) carcinoma is a rare disease with a poor prognosis because of its rapid progression and the androgen-independent characteristic, for which no successful therapy is available presently. We report a case of NE differentiated prostate cancer, which was diagnosed as adenocarcinoma initially and progressed with NE differentiation(More)
