Özet

Prevention of the production of thromboxane A(2) -a potent vasoconstrictor and aggregating metabolite of arachidonic acid- or infusion of the stable analogues of prostacyclin -which is another cyclooxygenase metabolite of arachidonic acid- has been shown to be beneficial in cerebral vasoconstriction. Endothelin-l, a peptide derived from endothelial cells, has been shown to induce a long-lasting cerebral vasoconstriction both in vivo and in vitro. The purpose of this study was to investigate the role of a novel thromboxane A(2)-synthase inhibitor UK 38485 on the acute vascular and morphological effects of Endothelin-l applied intra-arterially on rabbit basilar arteries.
