Effect of apamin on EFS-induced relaxation of longitudinal muscle in the jejunum. (A) Relaxations were induced by EFS at 10 Hz for 10 s before and after the treatment with apamin at the indicated concentrations. The lines indicate the presence of apamin in the bathing fluid. (B) Summary of effect of apamin on EFS-induced relaxation. Relaxations in the presence of indicated concentrations of apamin are expressed as a percentage of those obtained before the addition of apamin. Values are means±s.e.mean (vertical bars) for three to six experiments. For further details, see legend of Figure 1.
