To evaluate the participation of nitric oxide (NO) on pressure-induced natriuresis in pentobarbital-anesthetized dogs, renal perfusion pressure (RPP) was increased twice from 100 to 150 mmHg before and during the intrarenal administration of an NO-synthesis inhibitor, NG-nitro-L-arginine methyl ester (L-NAME), while determining changes in glomerular filtration rate (GFR), renal blood flow (RBF), and urine sodium and water excretion. Before the inhibition of NO, the increase in RPP induced diuresis (5-fold) and natriuresis (4.2-fold) with no change in RBF or GFR. However, the intrarenal infusion of L-NAME (1 microgram.kg-1.min-1) blunted the diuretic and natriuretic responses without altering RBF or GFR. The infusion of the NO synthesis precursor L-arginine prevented the inhibitory effect that L-NAME exerted on the diuretic and natriuretic responses to the increase in RPP. These results indicate that the increase in RPP stimulates NO synthesis and suggest that NO might play an important role in the control of sodium and water excretion during acute changes in RPP.
