Evaluation of the P. quadrangularis (Pq) vasodilatation mechanism associated with potassium channels. Effect of Pq after the addition of BaCl2 (10−5 M) as a nonselective blocker of inward rectifier potassium channels (Kir) is shown (A), glibenclamide (10−5 M) as blocker of Adenosine triphosphate (ATP)-sensitive K+ channels (B), and TEA (10−3 M) as a nonselective blocker of KCa1.1 channels (C). L-phenylephrine hydrochloride (PE) (10−6 M) was used to induce the contractile responses to the aortic rings. Data are the average ± SEM of 5 independent experiments. ** p < 0.01 and *** p < 0.001 vs. control.
