Abstract
SUMMARY: To evaluate the possible contribution of atrial natriuretic peptide (ANP) to the development of glomerular hyperfiltration, we examined the effect of nonpeptide competitive antagonist for biological receptors of ANP, HS-142-1, on glomerular filtration rate (GFR) and renal plasma flow (RPF) in diabetic rats. Increased GFR and RPF in diabetic rats were significantly ameliorated by the injection of HS-142-1, while blood pressure remained unchanged. Urinary cyclic GMP excretion was significantly higher in diabetic rats than in control rats and HS-142-1 decreased urinary cGMP excretion significantly. These results indicate that atrial natriuretic peptide contributes to the development of glomerular hyperfiltration and hyperperfusion in diabetes and HS-142-1 might be useful in the treatment of them.
