The mRNA expression of inflammatory cytokines and COX enzymes in the rat colon after treatment. Kanzo (K), Daio (D), or DKT was administered orally to rats once (A) or for 7 days (B), and the colon was collected 5 h after the last treatment. The mRNA expression of TNF-α, IL-1β, IL-6, COX-1, and COX-2 was analyzed using real-time PCR. The results were normalized to those of β-actin, which were indexed by setting the mean value in the control group to 100% (mean ± SD; n = 5; Tukey’s test: *p < 0.05, **p < 0.01 vs Cont.)
