Objectives Hataedock is an orally administered herbal extract treatment for newborn babies that dispels toxic heat and meconium gathered by the fetus. The purpose of this study was to evaluate whether Hataedock alleviates inflammatory skin damage in AD (Atopic Dermatitis)-induced NC/Nga mice through regulating and maintaining the skin barrier and anti-inflammation effects.Methods We established an AD model in three-week-old NC/Nga mice through the repeated application of DNFB (dinitrochlorobenzene) on days 28, 35, and 42 after Hataedock treatment was orally administered. We identified changes in the skin barrier and anti-inflammation effects through the histological and immunohistochemical changes of TNF- α, NF-κB p65, iNOS, COX-2, and apoptotic bodies.Results Skin damage and angiogenesis were mitigated in the HT (Hataedock) group. Damage to the intercellular space of the stratum corneum as well as hyperplasia, edema, the infiltration of lymphocytes, and the increase of capillaries decreased in the HT group. Our results suggest that Hataedock treatment significantly down-regulated levels of TNF- α by 38% (p<0.001) and of NF-κB p65 by 70% (p<0.001). But Hataedock up-regulated apoptosis by 183% in dermatitis-induced skin.Conclusions These results suggest that Hataedock alleviates AD through diminishing the various inflammatory cytokines in skin lesions that are involved in the initial steps of AD development. It might have potential applications for the prevention and treatment of atopic dermatitis.

Objectives : Adenophorae Radix(AR) is the dried root of Adenphora triphylla var. japonica HARA. AR has the efficacy of clarifying lung, emitting pus, expelling wind, stopping pruitus and so on. Recently, various studies are being done about anti-oxidative, immunomodulatory and anti-inflammatory effects of AR. So, we expected AR has an availability that can improve symptoms of atopic dermatitis(AD). Methods : In this study, we measured body weight, weight of ear, thickness of ear skin and dorsum skin, symptom score, reproduction rate of splenocytes in vivo and in vitro of mouse with AD induced by DNCB. We experimented with five groups of 9 mice, such as normal group, control group, AR spread(ARS) group, AR feeding(ARF) group, AR spread&feeding(ARSF) group. Results : Control group of body weight significantly reduced and APSF group significantly increased in the first and second week. In weight of ear and thickness of ear skin and dorsum skin, control group significantly increased and ARSF group significantly decreased. In macrophotography viewpoint of dorsal skin, ARS group, ARF group and ARSF group decreased severe pigmented skin lesion, erythema and desquamation as compared with control group. Especially ARSF group showed significant drop. ARS group, ARF group and ARSF group compared to control group were improved in histopathology observation. In vitro and in vivo, treatment group of AR increased proliferation rate of splenocytes, specially in vitro significantly. Conclusions : This experiment indicates Adenophorae Radix extracts is effective on AD induced by DNCB in mice.

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.

Atopic dermatitis (AD) is a common skin disease characterized by chronic and relapsing inflammatory dermatitis with immunological disturbances. In spite of the continuous increase in the incidence of AD, it is regrettable that till date there is no effective treatment to treat the same. Therefore, the present study was designed to examine the possible anti-atopic effects of Castanea crenata inner shell extracts fermented by Lactobacillus bifermentans (FCS) in 2,4-dinitrochlorobenzene (DNCB) induced AD in NC/Nga mice. Based on the results of HPLC analysis, we found that FCS contains anti-inflammatory factors such as gallic acid (10.18 mg/g) and ellagic acid (2.14 mg/g). The groups that we have used in this study included 0.1%, 1%, 5% fermented Castanea crenata inner shell extracts (FCS 0.1, FCS 1, FCS 5), 1,3-butylene glycol treated control (AD), and normal mice. After topical FCS treatment, we observed that the clinical severity score for AD was lower in both the FCS 1 and FCS 5 groups than the AD group. We also proved beyond doubt that there was improvement of melanin, erythema and skin moisture indices in the FCS 5 group. Spleen index and gene expression levels of pro-inflammatory cytokines such as IL-$1{\beta}$ and TNF-${\alpha}$ were significantly decreased in the FCS 5 group compared to the AD group (P<0.05). Further, we also found that the level of serum immunoglobulin E (IgE) in the FCS-treated group was decreased in a concentration-dependent manner. The results of our study suggest that FCS can be effectively used as a cosmeceutical ingredient for both the prevention and improvement of AD.

Atopic dermatitis (AD) is a chronically relapsing inflammatory skin disease that often has asthma and allergic rhinitis. Magnesium salts, the important component of minerals in Dead Sea water, are known to exhibit beneficial effects in inflammatory disease. Favorable effects of magnesium ions and sea water treated to the skin of patients with contact dermatitis have been reported. But histological and immunological investigations are insufficient. This study was performed to examine the inhibitory effect of magnesium-rich sea mineral water on the development of AD-like skin lesions in hairless mice. AD-like skin lesions are induced by the repeated application of 2,4-dinitrochlorobenzene (DNCB). Local application of magnesium-rich sea mineral water on hairless mice skin applied with DNCB inhibited the development of AD-like skin lesions as exemplified by a significant increase in skin hydration (p<0.01), and a decrease in epidermal water loss (p<0.01). Serum IgE level was also significantly decreased (p<0.01). These results suggest that magnesium-rich sea mineral water inhibits the development of DNCB-induced AD-like skin lesions in hairless mice. These observations indicate that magnesium-rich sea mineral water may be alternative and assistant substances for the management of AD.
