... (‘NO-clamping’). Slow volume expansion (saline, 20 μmol of NaCl·min −1 ·kg −1 of body weight for 3 h) was performed with and without concomitant NO-clamping. NO-clamping itself decreased RPF (renal plasma flow; P ~0.02) and tended to decrease arterial blood pressure [MABP (mean arterial blood pressure...

...Orawan WONGMEKIAT; Edward J. JOHNS The present study investigated the potential role of nitric oxide (NO) and its interaction with renal sympathetic nerves in modulating the excretory responses to an acute saline volume expansion (VE), of 10% of body weight, in the innervated and denervated kidneys...

...A. T. Veressa; C. K. Chong; H. Sonnenberg 1. The possible involvement of renal nerves in the diuresis and natriuresis of blood volume expansion was studied in anaesthetized rats. Acute unilateral renal denervation caused increased excretion of fluid, sodium and potassium. 2. Renal blood and plasma...
