Fig. 4. Inhibitory effect of Korean red ginseng (RG) on 1-chloro-2,4-dinitrobenzene (DNCB)-induced interleukin (IL)-4 secretion in splenocytes. After completion of all treatments, splenocytes (5×105 cells/well) were incubated for 24 h. Culture supernatants were collected and level of secreted IL-4 was determined using ELISA. The data are presented as the mean±SEM of a representative experiment of triplicates. Dex, dexamethasone. ##p<0.01, significantly different from control group; **p<0.01, significantly different from DNCB-alone.
