Oxytocin decreases colonic motility of cold water stressed rats via oxytocin receptors

Figure 2 Effects of oxytocin (0. 01-0.3 μmol/L) on colon contraction in intragastric cold water stressed rats. A: The dose-dependent contractile response to oxytocin (OT) in colonic smooth muscle strips in cold and control groups. OT was administered at the points marked by the arrows. B: Average response to OT in the colon. ^aP < 0.05 vs the data prior to OT administration. ^cP < 0.05 vs cold and control groups (n = 6).
