Comparison of mast cell numbers in colonic segments. In proximal colonic segments, mast cell numbers of stressed rats tended to be higher than those of non-stressed rats, and mast cell numbers of astressin-pretreated stressed rats were significantly lower than those of saline-pretreated stressed rats (*P=0.05) (A). In distal colonic segments, mast cell numbers of stressed rats were significantly higher than those of non-stressed rats (*P=0.04), and mast cell numbers of astressin-pretreated stressed rats were significantly lower than those of saline-pretreated stressed rats (†P=0.01) (B).
