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

Figure 5 Inflammatory cytokine expressions in the plasma and in the distal colon by western blot analysis following the 6 wk stress experiment. Note the prominent expressions of interleukin-2 (IL-2) and interferon-γ (IFN-γ) in the distal colon and in the plasma in the chronic variable stress (CVS)-A group only. ^aDenotes significant difference between control and other groups (^aP < 0.05). There was a significant difference in the relative density of IL-2 and IFN-γ in the plasma and distal colon between CON and the other groups. ^bDenotes significant difference between CVS-A and CVS-B group (^cP < 0.05 vs CVS-A groups). There was also a significant difference in the relative density of IL-2 and IFN-γ in the plasma and distal colon between CVS-A and CVS-B groups.
