OA and derivatives evoke a vasodilation in aorta and mesenteric arteries from DSS rats.

<p>Concentration-response curves for solvent, OA, Me-OA, and Br-OA in endothelium-intact mesenteric arteries [A, B] or aortic rings [C, D] isolated from DSS rats, pre-contracted with sub-maximal concentration of PE (5 μM) [A, C] and KCl (50 mM) [B, D]. The values shown are means ± SEM (n = 7). * p ˂ 0.001 vs control, <b>#</b> vs Br-OA.
