Effect of Atorvastatin/Pitavastatin on L-Methionine change in endothelium dependent relaxation using isolated rat aortic ring preparation. (L-Meth = L-Methionine; Atorva = Atorvastatin; Pitava = Pitavastatin). Each group (n = 10), represent mean ± SEM. Responses are expressed as % of maximum contraction induced by phenylephrine (3 × 10-6 M). a = p < 0.05 Vs Control. b = p < 0.05 Vs L-Methionine treated group.
