Changes in diameter of the basilar artery in response to arachidonic acid in the absence and presence of indomethacin (10 µM, n=4). Baseline diameter of the basilar artery was 128±10 µm under control conditions and 91±7 µm after preconstriction with U46619. Values are means±SE. * = P<0.001 versus control.
