The effect of mannitol upon glomerular ultrafiltration was examined in hydropenic Munich-Wistar rats. Superficial nephron filtration rate (sngfr) rose from 32.0+/-0.9 nl/min/g kidney wt to 42.0+/-1.6 (P < 0.001) in eight rats. Hydrostatic pressure gradients acting across the glomerular capillary (DeltaP) were measured in glomerular capillaries and Bowman's space with a servo-nulling device, sys...
BACKGROUND In primary focal and segmental glomerulosclerosis (FSGS) renal prognosis is poor if no remission of proteinuria can be obtained by treatment. In some patients a permeability factor, responsible for damaging the glomerular epithelial cell and detectable by an in vitro test (GVV-test), seems to be present in the serum. METHOD We determined the effects of an immunadsorption treatment ...
T he glomerular capillary wall is thought to function as both a sizeand charge-selective barrier. The concept of charge selectivity emerged from a series of now classic studies that used tracers such as dextran, peroxidase, and ferritin to evaluate the influence of molecular charge on glomerular filtration (1–5). The permeability of anionic derivatives of each tracer was lower than their neutra...
This study examined the role of transforming growth factor-beta (TGF-beta) in altering the glomerular permeability to albumin (P(alb)) during hypertension development in Dahl salt-sensitive (Dahl S) rats and whether TGF-beta acts by inhibiting the glomerular production of 20-HETE. The results indicate that the renal expression of TGF-beta doubles in Dahl S rats fed a high-salt diet for 7 days, ...
