it was found that the mesenteric action of dopamine ( given i.v . in the submaximal dose of 16 micrograms.kg-1.min-1 or intraarterially up to a dose of 40 micrograms.min-1 ) is primarily mediated via dopaminergic vasodilator and a alpha-adrenergic vasoconstrictor receptors , the net result of this competition usually being moderate vasodilation under natural conditions .
