Inhibitory effects of RJ on DNCB-induced AD skin symptoms in Balb/c mice. The mice were divided into five groups: Vehicle (Sham), DNCB + vehicle (Control), DNCB + RJ 4 mg/mL (RJ 4), DNCB + RJ 8 mg/mL (RJ 8), positive control (DEX). (A) Ear thickness was measured with a micrometer. Five mice were used per group. (B,C) Organ sizes were compared by photographic images. Organ and whole-body weight of five mice per group were measured. Five mice were used per group. The data shown are the mean ± SD of three independent experiments. Significant difference from control group, * p < 0.05, ** p < 0.01.
