In order to clarify the mechanism of unusual renal tubular dysfunction seen in a child with Shiga toxin (Stx)-mediated hemolytic uremic syndrome (HUS), we studied the renal biopsy specimens for Stx binding and apoptosis of renal tubular cells. A 7-year-old boy with Stx-2-mediated HUS demonstrated extensive renal tubular damage characterized by nonoliguric(More)
We studied the insertion/deletion (I/D) polymorphism of the angiotensin converting enzyme (ACE) gene in 78 patients with primary vesicoureteral reflux (VUR), and examined renal function by dimercaptosuccinate (DMSA) renoscintigraphy and diethylenetriamine-penta-acetic acid (DTPA) renogram in each genotype. Patients were classified into three genotypes(More)
BACKGROUND There is currently no established therapy for childhood IgA nephropathy (IgAN). Mizoribine, a newly developed immunosuppressive agent characterized as a safe and well-tolerated drug, has been widely used in diverse conditions. Our preliminary study demonstrated that mizoribine could reduce the amount of proteinuria in children with IgAN. The(More)
Renal biopsy was performed in a 12-year-old girl with hematuria and proteinuria which was first detected at the age of 7, and the findings were the mesangial proliferative glomerulonephritis with IgG and C3 deposits. The routine blood examination for the biopsy disclosed the presence of the prolonged activated partial thromboplastin time and the biological(More)
The purpose of the present study was to clarify the physiological response of peripheral blood vessels when some vibrational stimuli were given to five healthy young men (21-22) continuously and intermittently. The vasoreaction was observed on each subjects after the exposure to vibration at frequencies 18, 32, 64 and 125 Hz with acceleration level at 5 g(More)
