The purpose of this study was to evaluate the constrictive effect of endothelin, a peptide vasoconstric tor derived from endothelium, on canine basilar artery. Constriction was measured by an isometric ten sion recording method. Endothelin induced prolonged contraction of canine basilar artery in a dose dependent fashion, the estimated concentration at 50% contraction being (2.1 •} 0.5) &times;...
