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

Figure 4 Restraint stress-induced defecation. The number of formless stool and the total number of defecation during 1 h restraint stress in the 7 days PIC group were significantly larger than the corresponding values in control rats. (^aP < 0.05 restrained vs. unrestrained in control; ^bP < 0.01; ^cP < 0.05 restrained vs. unrestrained in 7 days PIC group; ^dP < 0.01; ^eP < 0.05 restrained 7 days PIC group vs. restrained control group; ^fP < 0.01).
