Figure 2. NAT significantly decreased the intestinal inflammation induced by overuse of antibiotics. (A) The length of the colon and (B) the ileocecal valve index. The effects of NAT on the mRNA expression of (C) TNF-α, (D) IL-1β and (E) IL-10, (F) IFN-γ, (G) IL-4 concentration and (H) the ratio of IFN-γ to IL-4 in the intestinal tissue. Data are presented as mean ± SEM. #P < .01, #P < .05 indicates significant difference from the control group; *P < .05, **P < .01 indicates significant difference from the AB group. β-Actin is the loading control.
