260 VASCULAR RESPONSES IN THE NEONATAL ISOLATED PERFUSED RABBIT KIDNEY: INTERACTIONS BETWEEN ANGIOTENSIN II AND NITRIC OXIDE

There is evidence for a critical role of the interaction between endogenous Endothelium. Derived Relaxing Factor or Nitric Oxdide (NO) and Angiotensin II (Ang II) in the control of adult renal hemodynamics. This study was designed to explore if such NO-Ang II interaction exists in the isolated developing rabbit kidney, perfused in presence of indomethacin 10. μmol/l and to see how such interaction evolves with renal maturation.
