Visceral hypersensitivity and altered colonic motility after subsidence of inflammation in a rat model of colitis

Figure 3 Summarized plots representing the rectal distension-induced AWR (A) and concomitant pulse rate change (B), the relationship between the AWR score and the extent of pulse rate change (C), and the relationship between intraballoon volume and intrarectal pressure (D) in each group. At 7 days PIC, AWR and tachycardia were exaggerated in response to rectal distension. Note the good linear correlation between the AWR score and the logarithmic D pulse rate, which was not significantly different between groups. Intrarectal pressure was linearly increased as the balloon inflated, and the fitted functions of two groups were not significantly different from each other. (^aP < 0.05, ^bP < 0.01).
