Objectives : Atopic dermatitis is a recurrent or chronic eczematous skin disease with severe pruritus. Although the pathogenic mechanisms of atopic dermatitis are yet unknown, recently hyperresponsive Th2 cells in the acute phase are reported as the important mechanisms. Cheonggisan(CGS) is used in oriental clinics for curing acute skin lesions of eczema, atopic dermatitis or urticaria. There have been no studies on the therapeutic mechanism of CGS for curing atopic dermatitis. We aimed to find out the therapeutic mechanism of CGS on atopic dermatitis, so we observed Th2 cell differentiation in EL 4 cells and $NF-kB$ p65 activation in RAW 264.7 cells. Materials and Methods : EL 4 cells were induced the increase of IL-4 mRNA expression by phorbol-12-myristate-13-acetate(PMA) and 4-tert-Octylphenol(OP) and treated with CGS extract. RAW 264.7 cells were induced the increase of cyclooxygenase(COX)-2 mRNA expression by lipopolysaccharide(LPS) and treated with CGS extract. Results : The PMA and OP induced IL-4 mRNA expression was dose-dependantly decreased in CGS treated EL 4 cells. The LPS-induced COX-2 mRNA expression was dose-dependantly decreased in CGS treated RAW 264.7 cells. Conclusion : The results may suggest that the CGS inhibits Th2 cell differentiation in EL 4 cells and inhibits $NF-kB$ p65 activation in RAW 264.7 cells.

Objectives : Allergic diseases have a various symptoms of hyperresponsiveness and recently hyperresponsive reaction in the chronic phase is reported as the important mechanisms. Cheonggisan(CGS) is used in oriental clinics for curing various skin diseases due to effect of controlling of pruritus. There have been studies on the anti-allergic effect and anti-inflammatory effect of CGS, but there had no study of anti-allergic effects in allergic late inflammation of CGS, so we aimed to find out the effects of CGS in allergic late inflammation in our study.Methods : To investigate the anti-allergy effect and anti-inflammatory effect of CGS, RAW 264.7 macrophage cells and CSG water-extracts were used. Cytotoxic effect of CSG was examined by MTT assay, an oxidative product of NO was measured in the culture medium by the Griess reagent assay. The level of prostaglandin E2(PGE2) was measured by competitive enzyme-linked immunoassay. Cytokine(PGE2, IL-1β, IL-6, TNF-α) was measured by Bio-Plex suspension assay system and quantitative multiplexed cytokine/chemokine assay.Results : We investigated that there was no cytotoxic effect of CGS water-extract at any levels of concentration on RAW 264.7 macrophage cells by MTT assay. CGS water-extracts significantly suppressed the levels of the inflammatory mediators such as NO and PGE2, cytokine of IL-1β, TNF-α at the level of 400 ㎍/㎖ CGS concentration. But there was no significant effect on IL-6 production suppression.Conclusions : These results suggest that CSG water-extract has and anti-inflammatory effects in allergic reaction. These properties may contribute to the allergic diseases and inflammatory related disease care.

Cheonggisan(CGS) is well known for its effect on such allergic disease as urticaria and atopic dermatitis. Gagamcheonggisan(GCGS) was formulated by subtracting several herbs from CGS and adding several herbs to CGS. Even though it is being used frequently in the clinicai medicine for the treatment of above hypersensitivity diseases, basic study to make sure the mechanism of its action is rare. In this study the author tried to know the effect of CGS and GCGS on the vascular permeability, contact dermatitis, granular secretion from mast cells and function of macrophages. The results obtained in this study are as follows : 1. Administration of CGS and GCGS decreased the vascular permeability induced by serotonin and histamine. The decrease by serotonin is more typical and dose-dependent. 2. Administration of CGS and GCGS inhibited foot-pad and ear swelling responses induced by sheep red blood cells and picryl chloride respectively, the inhibition of foot-pad swelling responses is bigger than that of ear swelling responses and both of them are not dependent on the dose3. Treatment of peritoneal mast cells with CGS and GCGS water extract decreased the histamine release triggered by compound 48／80 in a dose dependent fashion 4. Administration of CGS and GCGS increased the phagocvtic activity of peritoneal macrophages and treatment of peritoneal macrophages with CGS activated phagocytic function in a dose dependent fashion. 5. Administration of CGS and GCGS enhanced such reactive oxygen intermediates(ROIs) as superoxide and hydrogen peroxide production from peritoneal macrophages. 6. Treatment of CGS and GCGS activated peritoneal macrophages for the production of ROIs. The above results show that CGS and GCGS decreased the hypersensitivity reactions by inhibiting non-specific inflammatory mediator release and vascular permeability without affecting general immune responsiveness.

Objectives : Atopic dermatitis is a skin problem that causes dry skin, intense itching, and then a red, raised rash. It may be a long-lasting (chronic) skin problem that requires more than one treatment. The cause of atopic dermatitis isn't clear, but it affects the skin's ability to hold moisture. The skin becomes dry, itchy, and easily irritated. The purpose of this study was to report the clinical effects of herbal medicine on atopic dermatitis. Methods : We employed oriental medical treatments; herbal-medication (Cheonggisanbyeonbang), acupuncture, moxibustion and cupping therapy. At the same time, the patient sweated out the skin poison. We treated him two times a week with oriental therapy method. He took medicine three times a day after a meal. During taking medicine, we let him avoid fatty food, flour based food, and alcohol. We took a picture the patient's body parts and compared the symptom with previous symptom. With the picture, we evaluated the patient's condition. Results : After taking treatment - 17 times' acupuncture, moxibustion and cupping therapy during 4 months- and taking herbal-medicine, the skin condition of the patient was much improved. At first, he was troubled with itching and hot feeling at reddish area, time after time the itching and hot feeling was weakened. The reddish area was changed to dry condition and changed to normal state. In advance, the symptom of arms was improved, and later the symptom of legs was started to improve. Conclusion : Herbal medicine (Cheonggisanbyeonbang) was an effective in the treatment of atopic dermatitis and it helped to improve regenerating the skin in the body.
