Effect of D-tubocurarine on vagally mediated contractions in the rat esophagus. a Representative tracings of vagally mediated contractions in the intact and capsaicin (Cap)-treated rat esophagi, respectively, in the presence or absence of D-tubocurarine (0.5–5 µM) are shown. Electrical stimulations were applied to the vagus nerve using single 80-V pulses (pulse duration 100 μs; between-pulse interval 1 min). b Summary graphs of the effects of D-tubocurarine on vagal stimulation-evoked contractions in the intact (open circles) and the Cap-treated (filled triangles) rat esophagi, respectively (contraction after application of vehicle 100 %). Each data point represents the mean ± SD (intact n = 5, capsaicin-treated n = 3)
