Effect of Korean Red Ginseng extract (RGE) on 1-fluoro-2,4-dinitrobenzene (DNFB)-induced atopic dermatitis (AD)-like dermatitis. Comparison of DNFB-induced dermatitis in BALB/c mice after oral administration of RGE (5 mg/kg and 50 mg/kg) or Pre-RGE (50 mg/kg; upper panels) and hematoxylin and eosin (H&E) stained tissue sections (lower panels). Skin tissues were fixed with 10% formaldehyde embedded in paraffin and H&E staining was conducted. The immune cells (arrows) are indicated. Photographs were taken under a regular light microscope (100 × magnification). Blank, DNFB-untreated normal mice; DNFB, DNFB-treated AD mice; RGE, DNFB-treated AD mice administered RGE after 4 wk of DNFB treatment; Pre-RGE, DNFB-treated AD mice administered RGE after the first DNFB treatment.
