Figure 1: Clinical effect of PG extracts in DNCB-induced atopic dermatitis-like skin lesion of NC/Nga mice. (A) Clinical skin severity scores. Clinical severity score was defi ned as the sum of each score grades: 0 (None), 1 (mild), 2 (moderate) and 3 (severe) for fi ve manifestations: itching, erythema/hemorrhage, scaling/dryness. (B) Photographs for the clinical features of NC/Nga mice at the time of sacrifi ce. (a) normal control (NC), (b) postive control (PC), (c) PG1 (DNCB + PG 300 mg/kg), (d) PG2 (DNCB + PG 500 mg/kg), (e) DEX (DNCB + dexamethasone 1.5 mg/ kg). Data are presented as mean ± SEM (n = 6).
