The effect of aminoguanidine on urinary heparan sulphate levels in experimental diabetes.

Abstract:

:In the present study, we investigated whether the ameliorating effect of aminoguanidine on diabetes-related proteinuria and nephropathy is associated with glomerular basement membrane heparan sulphate contents. STZ-induced diabetic rats developed proteinuria (at the tenth week: diabetic rats, 713 +/- 418 mg protein per millimole creatinine; control rats, <30) and increased urinary heparan sulphate excretion (diabetic rats, 1,400 +/- 83 microg/mmol creatinine; control rats, 41 +/- 13; p < 0.001), suggesting loss of glomerular basement membrane charge. Aminoguanidine treatment of diabetic rats diminished urinary heparan sulphate levels (196 +/- 52), suggesting high incorporation of heparan sulphate-associated charge into glomerular basement membrane. Aminoguanidine administration to diabetic rats also relatively improved proteinuria (456 +/- 255). It is concluded that aminoguanidine treatment has a relative beneficial effect by restoring the diabetes-induced change in renal basement membrane heparan sulphate levels.
