The effects of ADP, ATP, 2-methylthio ATP, α, β-methylene ADP (α, βmeADP) and α,
βmeATP on smooth muscle tone and the responses to transmural nerve stimulation were …

When adenine nucleotides were administered to isolated guinea pig ileum longitudinal
muscle, two immediate effects were observed: a contractile effect and a concomitant …

The effects of some agonists acting at P 2 purinoceptors on guinea-pig isolated ileum
longitudinal smooth muscle have been examined. The preparation contracted in response to …

Abstract alpha, beta-Methylene ATP and ATP both produced concentration-dependent
contractions of the isolated mesenteric artery of the rabbit that were not inhibited by reactive …

1 We have studied both the electrophysiological and contractile effects of the purine
nucleotide, adenosine‐5′‐triphosphate (ATP), as well as a number of its structural …

The effects of adenosine 5'-triphosphate (ATP) and its analogues on the perfusion pressure
of the isolated mesenteric bed of the rat were examined in preparations at resting tone, and …

1 The present study was addressed to clarify the subtypes of P2‐purinoceptor involved in
ATP release and contraction evoked by α, β‐methylene ATP (α, β‐mATP) and other P2 …

1 Adenosine 5′‐triphosphate (ATP) and adenosine have been shown to contract the rat
colon muscularis mucosae, and the receptors at which they act have been classified as P2Y …

1 The ontogeny of P2‐purinoceptors in the longitudinal muscle and the muscularis mucosae
of the rat isolated duodenum was investigated by use of functional assays in tissues from …

The actions of ATP, 2-methylthioATP, α, β-methyleneATP, β, γ-methyleneATP, adenosine
and non-adrenergic, non-cholinergic inhibitory nerve stimulation were compared on the …
