  • 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.

  • 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.

  • Objectives In the theory of Korean Medicine, Cicadae Periostracum (CP) has been used to treat skin diseases such as inflammatory dermatitis, tetanus and pruritus. CP can reduce heat and disperse wind. In prior studies, anti-allergic effect and anti-inflammatory effect of CP were reported. However, there has been no report regarding the correlation of CP and allergic contact dermatitis (ACD). This study was performed to show the effects of CP in ACD induced by 2,4-dinitrochlorobenzene (DNCB) in mice. Methods In this experiment, the effects of CP on biological changes were measured, such as changes in ear and spleen weight, ear and dorsum skin thickness, clinical aspect on the dorsum skin and histological changes. The effect of proliferation rate of splenocytes was also investigated in vitro and vivo study. Results In results, CP application (CPA) group and CP application and administration (CPAA) group were significantly restrained in ear weight gain and increase in ear and dorsum skin thickness compared to the control group. In addition, CPA and CPAA group showed diminished erythema, desquamation, bloodstain, and marks. Also, the histological assessment showed that CP treatement diminished thickness of epidermis, hyperkeratosis, pigmentation and parakeratosis. Conclusions In conclusion, these data suggest that CP can decrease symptoms of ACD.
