TGF-beta plays a pivotal role in the pathological accumulation of extracellular matrix in experimental glomerulonephritis. Increased TGF-beta expression leads to increased synthesis and deposition of extracellular matrix components while administration of anti-serum to TGF-beta suppresses the major manifestations of the disease. We hypothesized that(More)
The incidences of cerebral hemorrhage (CH), cerebral infarction (CI) and subarachnoid hemorrhage (SAH) were examined retrospectively in patients with chronic renal failure on maintenance hemodialysis, followed for 13 years in our 26 satellite dialysis centers. During 10,364 patient-years of experience (PYE), CH developed in 66, CI in 16, SAH in 3 and(More)
BACKGROUND It has been found that brain atrophy develops more rapidly in patients with end-stage renal failure after initiation of dialysis therapy. The present study was designed to analyze the relationship between brain atrophy and asymptomatic ischemic brain lesions. PATIENTS AND METHODS Magnetic resonance imaging (MRI) was performed for the evaluation(More)
The effects of antihypertensive drugs on mesangial cell proliferation were studied in spontaneously hypertensive rats (SHR) with anti-thymocyte serum (ATS)-induced glomerulo-nephritis. Rats were treated with either enalapril (Group 1), nifedipine (Group 2), or reserpine + hydrochlorothiazide + hydralazine (Group 3), or were untreated (Group 4). The animals(More)
The renal hemodynamic response to pressor substances in the diseased kidney has been suggested to be different from that in the normal kidney. The aim of this study was to investigate the effects of endothelin and angiotensin II on renal hemodynamics in experimental nephritis induced by the administration of antithymocyte serum in Wistar rats. This model(More)
The plasma concentration and urinary excretion of a newly developed angiotensin I converting enzyme inhibitor, alacepril (which is converted to captopril after absorption), were investigated in seven normal healthy subjects. Fifty milligrams of the drug was administered orally either in the fasting or in the fed state. In the fasting state, the time of(More)
