Analysis of the progression of rheumatoid arthritis (RA) using a murine collagen-induced arthritis (CIA) model. Mice with CIA were orally administered 4-HMC or Dexa from day 28 after the primary immunization. RA severity was monitored based on the clinical arthritis score, the incidence of arthritic paws, and paw thickness, which was measured using a dial thickness gauge. The data are presented as the mean ± SD of five determinations. ∗∗∗p < 0.001; ∗∗p < 0.01; p < 0.05, significantly different from untreated CIA mice. 4-HMC, 4-(hydroxymethyl)catechol; Dexa, dexamethasone.
