Effect of PPADS and apyrase on rabbit USM contraction induced by 0.3-millisecond pulse duration, 4 Hz frequency, 30-second (s) EFS. Transient smooth muscle strip contraction was attenuated by 10 μM purinergic receptor inhibitor PPADS (A) and ATP diphosphohydrolase enzyme apyrase, which catalyzes ATP hydrolysis (C). Note summary data on these effects (B and D).
