Fig. 5. Effects of adenosine triphosphate (ATP) treatment with apamin pretreatment in the human colon segment. The contractility of the colonic segments did not decrease after 300 µM ATP administration with 500 nM apamin pretreatment in the right (A) or left colon (C). The amplitude, frequency, and area under the curve (AUC) did not statistically decrease after the administration of 300 µM ATP with 500 nM apamin pretreatment in the circular muscle (CM) or longitudinal muscle (LM) of the right colonic segment (B) and left colonic segment (D). Control, before 500 nM apamin; Amp, amplitude after 300 µM ATP; Freq, frequency after 300 µM ATP; AUC, area under the curve after 300 µM ATP; Rt, right; Lt, left.
