Figure 2. Wound closure from D1 to D3 (expressed as a percentage of the D0 WD) after the different treatments. The positive control PBS and the three CsA formulations have nearly identical wound closure rates of reepithelialization from D1 to D3. The negative control, 0.02%BAK, increased wound size and inhibited the healing process from D1 to D3. * p<0.0001–0.02 compared to the other four groups at the corresponding times.
