Stress worsens colonic damage and increases mast cell infiltration in the vesicles. A, Endo groups have more colonic damage when compared to sham-no stress group (^### P < .001 vs sham-no stress group). The endo-stress group has more damage than the endo-no stress group (n = 12 ± SEM, *P < .05 vs endo-no stress group). B, There was a significant increase in mast cell numbers in the vesicles of endo-stress animals when compared to the endo-no stress animals (n = 30-34 vesicles ± standard error of the mean [SEM], **P < .01 vs endo-no stress animals).
