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

Figure 7 Ovariectomy decreased the oxytocin-induced inhibition of colonic contractility in intragastric cold water stressed rats. A: Representative traces of the effect of ovariectomy (OVX) on oxytocin (OT)-induced colonic response in cold group rats. The drug was administered at the points marked by the arrows. OT-induced inhibition of colonic strips decreased after the rats were ovariectomized. B: The contraction of colonic smooth muscle strips in cold group rats. ^aP < 0.05 vs the data in normal Krebs solution. ^cP < 0.05 vs cold group and OVX + cold group (n = 6).
