there was no increase in atp release during contraction resulting from direct muscle stimulation following nerve paralysis with tetrodotoxin.4 sympathectomy with 6-hydroxydopamine did not affect release of atp in response to intramural nerve stimulation.5 release of atp was dependent on the concentration of calcium ion in the medium.6 contractions in response to non-adrenergic , non-cholinergic intramural nerve stimulation were closely mimicked by atp , but not by acetylcholine or histamine.7 adenosine and dipyridamole reduced the contractions to both atp and non-cholinergic nerve stimulation.8 2-2'-pyridylisatogen was not a specific blocker of either atp or intramural nerve stimulation in the guinea-pig bladder .
