title: Plasma renin activity in acute renal failure induced by norepinephrine infusion in unilaterally nephrectomized dogs.
abstract: Plasma renin activity was determined by bioassay prior to, during and following a 2-hour infusion of norepinephrine into the renal artery in unilaterally nephrectomized dogs in order to examine the role of renin-angiotensin system in norepinephrine-induced ARF. ARF was induced in 5 of 8 dogs receiving 0.75 microgram/kg/min of norepinephrine, but not in the remaining 3 dogs and 2 dogs infused with 0.6 and 0.4 microgram/kg/min of norepinephrine. There proved no difference in plasma renin activity in renal venous blood between the dogs with and without ARF when followed up to 2 h after the discontinuation of the infusion. The same results were obtained when the plasma renin activity in the foreleg vein was followed at 24, 48 and 72 h after the infusion. The renin-angiotensin system does not seem to contribute to the reduction of renal function in norepinephrine-induced ARF in dogs.
