Fig. 5From: Alteration of neuromuscular transmissions in the hamster colon following the resolution of TNBS-induced colitisEffects of inflammation on mechanical responses elicited by EFS in an isolated segment of the hamster colon. Representative tracings of EFS-mediated contraction and relaxation in intact and inflamed hamster colons at 7 or 30 days after trinitrobenzene sulfonic acid (TNBS) treatment are shown. Electrical stimulation was applied using multi-pulses of 20 V each, with a 0.3-ms pulse duration at 2 Hz (a) or 20 Hz (b) for 1 s; longitudinal mechanical responses were recorded isometrically.
