Abstract：
:The role of endogenous atrial natriuretic peptide (ANP) in the immediate response of sodium excretion to unilateral nephrectomy (UNX) was investigated in anesthetized euvolemic rats through measurement of UNX-induced change in plasma ANP concentration and the response of the remaining kidney to UNX following administration of monoclonal anti-ANP antibodies. The circulating ANP levels almost tripled (from 23 +/- 4 to 66 +/- 13 fmol/ml, P < 0.01) within two minutes after UNX, whereas no change resulted from sham intervention. In the control group receiving vehicle injection, UNX resulted in a twofold increase in urinary sodium excretion (from 1.39 +/- 0.25 to 2.88 +/- 0.28 mumol/min, P < 0.01) related to a decrease in the fractional reabsorption of sodium at both proximal and distal sites (estimated from fractional excretion of lithium). Urinary excretion of cyclic guanosine 3'-5'-monophosphate (cGMP) increased as well, but glomerular filtration rate did not change. In addition, UNX was associated with a short-lived (< 20 min) rise in systemic arterial pressure and a transient fall in right atrial pressure. Administration of monoclonal anti-ANP antibodies totally prevented the UNX-associated natriuresis by blunting both proximal and distal tubular reabsorption of sodium, and suppressed the rise in urinary cGMP excretion following UNX. The duration of the post-UNX increase in arterial pressure was longer when compared to values observed in controls. These observations indicate that ANP release is stimulated after uninephrectomy.(ABSTRACT TRUNCATED AT 250 WORDS)
