Abstract

We tried to induce selective perivascular purinergic nerve stimulation in isolated canine splenic arterial preparations, using the cannula insertion method.Under the conditions of periarterial electrical stimulation(ES), i.e., trains of 1, 3 and 10 pulses, 1−ms pulse duration and 10−V amplitude at 1 Hz, monophasic vasoconstriction was consistently induced.The ES−induced vasoconstriction was not influenced by prazosin in doses that completely inhibited noradrenaline−induced vasoconstrictions, but it was suppressed by α, β−methylene ATP, a P2X purinoceptor desensitizer.Thus, it is indicated that a selective purinergic transmitter release is readily obtained in the isolated splenic arterial preparation.
