Abstract

1. The hypothesis that endothelin (ET) influences sympathetically mediated vasoconstriction was investigated in 13 healthy, male subjects. 2. ET (1 pmol min-1) was infused for 60 min into the left brachial arteries of seven healthy male subjects. Resting forearm blood flow, and sympathetic vasoconstriction produced by lower body negative pressure (LBNP; 15 mm Hg), was measured in both arms by strain gauge plethysmography. In a further six subjects, noradrenaline (NA) was infused intra-arterially at doses of 150-600 pmol min-1, with and without co-infusion of ET (1 pmol min-1), with blood flow measured in both forearms. 3. ET produced a small but significant reduction of blood flow in the infused forearm from 3.9 +/- 0.6 ml 100 ml-1 min-1 during infusion of saline, to 3.3 +/- 0.7 ml 100 ml-1 min-1 during infusion of ET at 60 min (P less than 0.05). Blood flow in the non-infused forearm was not altered by ET infusion. 4. NA produced a significant and dose-dependent reduction of blood flow in the infused forearm from 3.13 +/- 0.5 ml 100 ml-1 min-1 during saline infusion, to 1.49 +/- 0.2 ml 100 ml-1 min-1 with NA at 600 pmol min-1 (P less than 0.001). During co-infusion of ET, blood flow was reduced similarly in the infused arm from 3.15 +/- 0.7 ml 100 ml-1 min-1 during saline infusion to 1.55 +/- 0.2 ml 100 ml-1 min-1 with NA at 600 pmol min-1. Blood flow in the non-infused arm was not altered by ET and NA infusion.(ABSTRACT TRUNCATED AT 250 WORDS)
