Figure 7

Effects of CTD-1 on DTH responses in BALB/c mice. BALB/c mice were initially sensitized with DNFB on days 0 and 1 and then challenged with DNFB on day 9. Vehicle and CTD-1 were administered after the first challenge. Ear swelling was calculated as the difference between the weights (a) or thickness (b) of left (DNFB treated) and right (untreated) ear punches 24 h after challenge. Treatment by CSA (1 mg/Kg) was set as positive group. Data are expressed as mean ± S.D. , , mice/group.
