Allergic contact dermatitis is a common skin disease resulting from specific immunologic to topically applied various allergen. After Dinitrochlorobenzene (DNCB) secondary sensitization, the ICR mice administered Rhemanniae radix extract (RRE) was observed to ascerstain the effect of RRE on allergic contact dermatitis. Purpose of this study was to investigate contact hypersensitivity assay, abdominal skin morphologic changes. Including mast cells and cell-surface glycoconjugates. The change of interleukin 2 (IL-2) receptor (CD25R). ICAM in abdominal skin, lymph node of inguinal region, and electro microscope-morphologic changes of abdominal skin. The results of this study were as follows: 1. The contact hypersensitivity assay, the ear swelling in the RRE had lesser probability than in the ACD Group. 2. In the general morphologic change of skin, hyperplasia of keratinocytes, distribution of vasculogenesis and epidermal lymphocytes infiltration were decreased in the RRE group compared with the ACD group. In epidermal basal layer and prickle layer, cell damage was decreased in the RRE group compared with the group painted with ACD. 3. MasT-cell in dermis was decreased in the RRE group compared with the group painted with DNCB. 4. Distribution of interlukin-2 Receptior positive cell and ICAM positive cell in dermis was decreased in the RRE Group compared with the ACD group. 5. Distribution of helper T-lymphocyte and cytotoxic T-lymphocite in inguinal nodes was decreased in the RRE group, and was observed well in paracortical area and cortical cord. 6. Distribution of apoptotic cell was appeared in the RRE group compared with the ACD group, in skin, dermis. in inguinal nodes, paracortical area observed well. With above results, the restarint of immunosuppression occuring in Allergic contact dermatitis is resulted in the slow progress the effect of Allergic contact dermatitis, and it is thought that ithis fact has a series of relation with apoptosis.

The purpose of this study was to investigate the efficacy of Torreyae semen extract against antimicrobial and allergic contact dermatitis to explore its utility as a herbal resource. To this end, the antibacterial effects of Torreyae Semend extracted with hot water and ethanol (30%, 60%, 90%) were investigated using Staphylococcus aureus, Staphylococcus epidermidis, pseudomonas aeruginosa, and Propionibacterium acnes. And observed the anti-atopic dermatitis efficacy with a mouse model that allergic contact dermatitis induced by DNCB. Experimental results showed that the antibacterial activity against S. epidermidis and P. aeruginosa was significantly higher in the hot water extract of Torreyae Semen. We observed that the extracts of 30% ethanol and hot water of Torreyae Semen inhibited growth in a concentration-dependent manner in P. acnes & S. epidermidis. We observed that the administration of hot water extracts and 30% ethanol extract of Torreyae Semen significantly reduce the thickness of ear & back and gross skin condition compared to the control group in the mice with allergic contact dermatitis. As a result of H & E histological staining, it was observed that the Torreyae Semen extraction group had markedly reduced epidermis and skin thickness, granules, and keratinization compared to the control group. The groups administrated with Torreyae Semen hot water extracts had decreased TNF-α and IL-10 contents compared with the control group. As a result, Torreyae Semen may be used as a useful herbal resource because it has a certain level of antibacterial and anti-atopic effects.

Objectives In the theory of Korean medicine, rice straw (RS) has been used effectively as treatments for dyspepsia, diarrhea, enteritis, inflammatory epigastric diseases and various dermatitis. However, the theory has not been studied intensively yet about anti-inflammatory effects for human. This study was to investigate effects of RS for a treatment of allergic contact dermatitis (ACD) induced by 2,4-dinitrochlorobezene (DNCB) in mice. Methods In this experiment, effects of RS were investigated on changes in body weights, dorsum skin thickness, clinical aspects on the dorsum skin, spleen and body weight among these four groups; normal group (NOR), control group (CON), RS spread group (RSS) and RS spread and administer group (RSS+Adm). In addition, the effects on proliferations of splenocytes were also investigated in vitro and in vivo study. Results RSS group and RSS+Adm group showed increasing in body weights, diminished dorsum skin thickness and treated dermatitis on dorsum skin. In RSS+Adm group, spleen weights were lowered significantly compared to CON group. Conclusions In conclusion, these data suggest that RS can decrease symptoms of ACD significantly, and it shows the anti-inflammatory and immunosuppressant effect as well. Therefore, RS can be useful to treat patients with ACD.

This study was performed to investigate the effectiveness of Hangryunhaedocktang (HHT) on epidermal damages induced by allergic contact dermatitis (ACD). The sensitization were caused by one application of $25{\mu}l$ of 5% 2,4-dinitroch1orobenzene (DNCB) onto a back-lumbar skin of BALB/c mice. 2 weeks later, ACD was elicitated with $4{\mu}l$ of 2.5% DNCB and then mice were given HHT extract in doses of 3.3ml/kg/day, for 72 hours. The ACD induced epidermal damages in HHT treated ACD mice was more mitigated than non-treated ACD elicited mice. The features related with epidermal damage such as epidermal hyperplasia, infiltration of inflammatory cells, increase of nuclear shrinkages and vacuolation, and enlargement of intercellular space softened. And the distribution of soybean agglutinin (SBA) positive reaction in stratum spinosum (SS) and stratum basale (SB) were similarly maintained in a normal configuration. The numerical decrease of BrdU, TUNEL, and Fas positive cells observed were prominent in SB. Results suggest a benefit role for HHT in mitigating epidermal damages in mice with allergic contact dermatitis.

NC/Nga mice with contact dermatitis induced using DNCB were applied with GJHB(祛風燥濕解毒方), and its influence on the expressions of IgE, immune related cytokines, and immunoglobulins were tested. The results were obtained as follows ; GJHB significantly redued the production of IgE compared to the control. GJHB significantly reduced the amount of IL-4 within the suspension of spleen cells, but significantly induced the production of $IFN-{\gamma}$, compared to the control. GJHB significantly reduced the production of IL-6 and $TNF-{\alpha}$ in the serum compared to the control. GJHB significantly suppressed the concentration of IgM, IgG2a, IgG2b in the serum. However, no significant decrease of IgG1 was observed. From the results above, GJHB suppressed the intermediate factors during the hypersensitive immune response as well as suppressing the generation of inflammation related cytokines. Therefore, anti-allergic effect of GJHB on the contact dermatitis through immune modulation was confirmed.
