Background and Objectives: Allergic contact dermatitis is a common environmental health issue and seriously affect the patient’s quality of life. The more our environment industrialized, the number of material that could cause the allergic contact dermatitis has been increased, consequently the prevalence of allergic contact dermatitis has been increased. In oriental medicine, clinically Chogam-Tang has been used fur the treatment of allergic dermatitis, eczema, atopic dermatitis etc. The objective of this study is to investigate the effects of Chogam-Tang on allergic contact dermatitis
Meterial and Methods: Fifteen Sprague-Dawley rats were divided into three groups: normal, control, experimental group. Control and experimental group were induced allergic contact dermatitis, by DNCB. Experimental group was orally administered the Chogam-Tang. Each group was observed after 24, 48 and 72 hours. Contact hypersensitivity assay, melanin-erythema measurement, pH measurement skin moisture measurement and biopsy were performed.
Results: 1. In contact hypersensitivity assay, experimental group showed decreased ear swelling compared with control group at 48hours. 2. ln melanin measurement there was no difference in three groups. 3. In erythema measurement experimental group showed reduction at 48. 72 hours. 4. In pH measurement, experimental group and control group showed increase in pH but there was no statistical significance. 5. In skin moisture measurement, experimental group showed higher skin moisture level than control group at 24 hours and showed lower skin moisture level at 72 hours, but there was no statistical significance. 6. In biopsy, experimental group showed decrement of Iymphocyte as time goes by, and regeneration of keratin layer was increased compared with normal group.
Conclusions: Chogam-Tang shows anti-inflammatory effect in biopsy, improves hydration levels of skin, decreases erythema level on allergic contact dermatitis.
