title: Dopamine enhances the action of prolactin on rat blood vessels. Implications for dopamine effects on plasma prolactin.
abstract: It has been claimed that dopamine enhances peripheral uptake of prolactin. Dopamine at 2.1 x 10(-9)M, a concentration which had no effect by itself, enhanced both the potentiation of rat mesenteric vascular reactivity caused by 50ng/ml ovine prolactin and the inhibition of reactivity caused by 500ng/ml prolactin. These observations are consistent with the proposal that dopamine can interact peripherally with prolactin.
