Abstract:
Exposure of the isolated rat tail artery to exogenous noradrenaline inhibited vasoconstriction induced by electrical field stimulation. Phenylephrine produced brief inhibition; guanfacine potentiated electrical stimulation. Sympathetic neurotransmission may be blunted by brief increases in circulating noradrenaline levels.
