Glomerular Permeability
Ferritin was used as a tracer to investigate glomerular permeability in the nephrotic rat. The results were compared with those previously obtained in normal animals. A nephrotic syndrome was induced by 9 daily injections of the aminonucleoside of puromycin. Ferritin was administered intravenously on the 10th day, and kidney tissue was fixed at intervals of 5 minutes to 44 hours after injection...
متن کاملGlomerular Permeability
Wistar/Furth rats were made nephrotic by daily administration of amino-nucleoside of puromycin, and the ultrastructural localization of horseradish peroxidase (mol wt 40,000) in the renal glomerulus was studied from 1 min to 20 hr after intravenous injection of the tracer. In control rats, peroxidase permeated the endothelial fenestrae, the basement membrane, and the epithelial slits, and was p...
متن کاملStructural determinants of glomerular permeability.
Recent progress in relating the functional properties of the glomerular capillary wall to its unique structure is reviewed. The fenestrated endothelium, glomerular basement membrane (GBM), and epithelial filtration slits form a series arrangement in which the flow diverges as it enters the GBM from the fenestrae and converges again at the filtration slits. A hydrodynamic model that combines mor...
متن کاملPodocyte Damage and Glomerular Permeability
The renal glomerulus, the site of plasma ultrafiltration and the production of primary urine (1), is the locus of a number of progressive disorders that lead to chronic renal insufficiency. Before the advent of renal replacement therapies, these diseases invariably led to death by uremia. Still, while these treatments save, or at least extend, patient’s lives, they do so at an enormous price, b...
متن کاملWhat determines glomerular capillary permeability?
There have been exciting recent advances in our understanding of the structural and molecular biology of the glomerular slit diaphragm, as described in a report in this issue of the JCI. These findings, combined with data on the permeability of the basement membrane and evidence that the endothelium may be a more important barrier than often supposed, are allowing a clearer understanding to eme...
