P40 peptide vaccine treatment ameliorates intestinal inflammation in established TNBS-induced chronic colitis. Colonic specimens were formalin-fixed and embedded in paraffin blocks, and then 6-μm sections were stained with hematoxylin and eosin (H&E). A, Representative H&E staining histological images of colon samples (original magnification x 100). B, Representative H&E staining histological images of colon samples (original magnification x 200). C, Semiquantitative analysis of histological inflammation. H&E scores 0–10 were given for each mouse. (**, P < 0.01).
