Abstract

A study of anionic sites in the glomerular basement membrane (GBM) of streptozotocin (STZ)-induced diabetic rats with or without treatment by an antiplatelet drug, dilazep dihydrochloride, is described. Expression of glomerular extracellular matrix (ECM) components was examined by immunofluorescence. Renal specimens were immersed in polyethyleneimine (PEI) as a cationic probe and then examined by electron microscopy. Renal specimens were also incubated with rabbit antirat type IV collagen, laminin, and fibronectin antisera and then stained with fluorescein isothiocyanate (FITC)-labeled goat antirabbit IgG antiserum. Mean values of proteinuria in the dilazep-treated diabetic rats were significantly decreased compared with those in nontreated diabetic rats. There was no significant correlation between the levels of proteinuria and those of creatinine clearance (CCr). Number of anionic sites on the GBM in the dilazep-treated diabetic rats were greater than those in diabetic rats. There was no significant difference in the staining of such ECM components between both rat groups. The authors concluded that the dilazep dihydrochloride might prevent anionic charges on the GBM and decrease the urinary excretion of proteins in STZ-induc...Continue Reading

Basement Membranes

Basement membranes are thin, specialized extracellular matrices surrounding most tissues in all metazoans. Here is the latest research on basement membranes.
