Abstract:
:Renal extraction and renal plasma clearance of atrial natriuretic peptide from pigs with complete unilateral ureteral obstruction (UUO) and from intact anaesthetized pigs were determined from arteriovenous differences in plasma atrial natriuretic peptide and measured renal plasma flow. The effect of administration of either a cyclooxygenase inhibitor or an angiotensin converting enzyme inhibitor was examined during UUO. Renal extraction ratio and renal clearance rate of plasma atrial natriuretic peptide (ANP) in the intact pig was stable during the 15 h observation period. UUO resulted in a significant (P < 0.05) temporary increase in renal extraction ratio and a significant (P < 0.05) reduction in the renal clearance rate of atrial natriuretic peptide. During cyclooxygenase inhibition there was a significant increase in the renal extraction ratio of ANP. During angiotensin II converting enzyme inhibition, renal handling of atrial natriuretic peptide did not differ from that observed in control animals. The present data demonstrate that atrial natriuretic peptide is extracted by the obstructed kidney. Despite the significant reduction in renal blood flow during indomethacin administration, renal clearance of ANP was unaltered. The increase in ipsilateral renal extraction of atrial natriuretic peptide immediately after ureteral obstruction and indomethacin administration could be explained either by a direct influence of PGE2 on the renal haemodynamics altering renal extraction of ANP, or by a compensatory mechanism attempting to preserve renal function.
