Fig. 3From: Lidocaine relaxation in isolated rat aortic rings is enhanced by endothelial removal: possible role of Kv, KATP channels and A2a receptor crosstalkConcentration-response curves to lidocaine with and without the presence of L-NAME + indomethacin in intact isolated rat aortic rings. Relaxation is expressed as percent of maximal relaxation to 100 μM papaverine. Points represent mean ± S.E.M of aortic rings. *P < 0.05 statistically different in the presence of L-NAME + indomethacin compared to control on intact rings. Lidocaine concentrations are on a log scale. Total animals n = 12Back to article page
