Hydrogen sulfide dilates rat mesenteric arteries by activating endothelial large-conductance Ca(2+)-activated K(+) channels and smooth muscle Ca(2+) sparks

We have previously shown that hydrogen sulfide (H(2)S) reduces myogenic tone and causes relaxation of phenylephrine (PE)-constricted mesenteric arteries. This effect of H(2)S to cause vasodilation and vascular smooth muscle cell (VSMC) hyperpolarization was mediated by large-conductance Ca(2+)-activ...
