From: The effect of mepivacaine on swine lingual, pulmonary and coronary arteries
Dose-dependent response of mepivacaine on lingual, pulmonary and coronary vasorelaxation. Endothelium-denuded lingual, pulmonary and artery rings were challenged with a cumulative dose of mepivacaine. Tension was determined by isometric force transduction, and is expressed as a percentage of the 40 mM KCl-induced contraction (N = 6). N indicates the number of arterial rings
