Fig. 2From: 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 in intact and denuded 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 statistical difference in responses between the intact and denuded rings. Lidocaine concentrations are on a log scale.
