Fig. 2. Inhibitory effect of Korean red ginseng (RG) on 1-chloro-2,4-dinitrobenzene (DNCB)-induced scratching behavior. Scratching behavior was observed after completion of all treatments. In brief, the number of scratching behaviors was counted for 10 min. Measurement was repeated for five times (50 min in total). Each bar shows the mean±SEM of three independent experiments. Dex, dexamethasone. ^##p<0.01, significantly different from control group; **p<0.01, significantly different from DNCB-alone.
