Abstract

1. Intrarenal arterial infusion of a direct adenylate cyclase activator (NKH477; 300 ng/kg per min) increased renal blood flow, urine flow rate and urinary sodium excretion in anaesthetized dogs. 2. Intrarenal arterial infusion of endothelin (ET)-1 (2 ng/kg per min) reduced basal values of these parameters and glomerular filtration rate, which were recovered by the addition of NKH477 during ET-1 infusion. 3. These results demonstrate that NKH477 can counteract ET-1-induced antinatriuresis, mainly by restoring glomerular filtration.
