Abstract：
:We studied the voltage dependence of the inhibitory effects of the Ca2+ antagonist Mg2+, compared to nifedipine, on the transsarcolemmal Ca2+ uptake into primary monolayers of smooth muscle cells obtained from pig coronary arteries. The cellular Ca incorporation was analyzed by liquid scintillation. Depolarization was produced by elevation of K+0. The data suggest that depolarization known to improve the inhibition by organic Ca2+ antagonists of L-type voltage-gated Ca2+ channels attenuates the Ca2+ antagonism of Mg2+ at vascular smooth muscle cells.
