Figure 6.
(A) In a reserpine-treated animal with mucosa present, combined application of SDZ-205-557 and ondansetron caused temporary inhibition of peristalsitic contractions which recovered even with increasing concentrations up to 5 μM. (B) Shows changes in amplitude of peristaltic contractions from individual animals. It is apparent that when these contractions recovers the amplitudes are unaffected in the majority of preparations, even up to 10 μM in concentration. (C) Shows that 5-HT has been depleted from myenteric ganglia in response to reserpine treatment.
