Sweet food improves chronic stress-induced irritable bowel syndrome-like symptoms in rats

Figure 4 Relative weight of the adrenal gland (A), plasma corticosterone levels (B), ACTH levels (C), and the ratio of corticosterone/ACTH following the 6-wk stress experiment. Denotes significant difference between control and other groups (^aP < 0.05 vs control groups). There was a significant difference in plasma corticosterone and adrenocorticotropic hormone (ACTH) concentrations between CON and the other groups. Denotes significant difference between chronic variable stress (CVS)-A and CVS-B group (^cP < 0.05 vs CVS-A groups). There was a significant difference in plasma corticosterone and ACTH concentration between CVS-A and CVS-B groups. CVS: Chronic variable stress.
