The patient, a white boy, had 3 episodes of recurrent acute glomerulonephritis at 7, 12 and 17 years of age. The episodes were preceded by impetigo and there was a good clinical and laboratorial recovery after all of them. Renal biopsies were performed during the acute episodes, and the light, immunofluorescence and electron microscopy studies showed only(More)
The natriuretic action of the atrial natriuretic factor (ANF) was studied in massively proteinuric, anti-natriuretic and edematous nephrotic rats with moderate impairment of renal function. Animals were distributed among four groups: NA----NR, NV----NR, NeA----NR and NA----NeR, where normal atrial (NA) or normal ventricular (NV) or "nephrotic" atrial (NeA)(More)
Three experimental protocols were used: a) normal and partially hepatectomized rats were expanded with isotonic saline; b) normal rats were expanded with isotonic saline; b) normal rats were infused with hypertonic saline (5%), either by the femoral or portal vein and c) hypertonic saline was sequentially and alternatively infused into normal rats via(More)
The renal tubular handling of sodium was evaluated in 10 normal (N), 9 edematous nephrotoxic serum nephrotic (Ne), 9 pyelonephritic (Py) and 12 partially nephrectomized (Nx) Wistar rats during maximal free-water clearance induced by intravenous infusion of hypotonic sodium chloride solutions. Fractional deliveries of sodium to distal nephron [(CH2O +(More)
