Fig. 2From: Implication of Porphyromonas gingivalis in colitis and homeostasis of intestinal epitheliumGross and histological evaluation of colon. (a) Colon length was measured from proximal colon to rectum. (b) Destruction of epithelial structure and scattered infiltration of inflammatory cells were assessed as histopathological score in H&E stained section of colon tissues. Results are shown as mean ± SD. Representative areas showing the damaged area with typical structure destruction and leukocyte infiltration (black box) were magnified. In (b), p-value significance was calculated by comparing other groups against (+) group (marked as +). *P < 0.05, **P < 0.01Back to article page
