본 실험은 황금이 Allergy성(性) 접촉피부염의 면역과민반응 및 염증반응에 미치는 영향을 조사하기 위해서 시행되었다. 실험을 위해 BALB/C계 생쥐를 DNCB 처리군과 DNCB 처리 후 황금추출액을 경구 투여한 황금추출물투여군(HGET군)으로 나누어 2,4-dinitrochlorobenzene(DNCB)를 도포하여 Allergy성(性) 접촉피부염을 유발한 뒤, 시간의 경과에 따라 contact hypersensitivity assay, 피부의 일반적인 구조, 혈관생성, 림프구를 비롯한 염증세포, sulfated acid mucosubstance, 비만세포, IL-2 R, ICAM-1 그리고 CD11b의 변화를 관찰하였다. Contact hypersensitivity assay에서 HEGT군은 DNCB처리군에 비해 유의성(有意性)있는 ear swellig의 감소를 보였다. 피부표피의 변화에서 HEGT군에서 DNCB처리군에 비해 감소된 것으로 나타났다. 또한 혈관생성, 림프구의 침투 및 표피 기저층과 가시층 세포의 손상은 HEGT군에서 DNCB처리군에 비해 감소된 것으로 나타났다. 또한 혈관생성, 림프구를 비롯한 염증세포, sulfated acid mucosubstance와 비만세포, IL-2 R 양성반응세포, ICAM-1 양성반응세포 그리고 CD11b 양성반응은 Allergy성(性) 접촉피부염의 면역과민반응억제와 항염증작용에 효과가 있는 것으로 사료된다.

1. The purpose of study To study the effectiveness of Yangkyuksanhawtang(YST) against Allergic Contact Dermatitis(ACD) I observed the change of cutaneous shape, histochemistry, immunohistochemistry, and the distribution of apoptotic cells. 2. The material and method of study I divided 4-month-old rats into three groups of 10, which are a contrastive group of having applied Acetone olive oil only, ACD group to have intentionally activated Allergic Contact Dermatitis by DNCB and YST group to give medication of Yangkyuksanhawtang extract. And I observed each group of mice after 24, 48 and 72 hours. 3. The result and conclusion of study The change of cutaneous shape and hypersensitive reaction of immunity was significantly decreased by YST in ACD rats. I consider that YST suppressed hypersensitive reaction of immunity and inflammation in ACD.

Objective : To study the effectiveness of Yangkyuksanhawtang against Allergic Contact Dermatitis I observed the change of cutaneous shape, histochemistry, immunohistochemistry, and the distribution of apoptotic cells. materials and methods : I divided 4-month-old rats into three groups of 10, which are a contrastive group of having applied Acetone olive oil only, ACD group to have intentionally activated Allergic Contact Dermatitis by DNCB and YST group to give medication of Yangkyuksanhawtang extract. And I observed each group of mice after 24, 48 and 72 hours. results : 1. With the result of Contact hypersensitivity assay, YST group shows appreciably less ear swelling than ACD group. 2. Comparing YST and ACD groups to each other regarding general change of skin, YST group shows less hyperplasia of epidermis, less migration of inflammatory cells and less damage of epidermis than ACD group. 3. Regarding the change of collagen fiber, ACD group has appeared to be low in number of collagen fiber while YST shows similarity with the contrastive group. 4. In dermis YST group has showed lower number of mastocyte than ACD group and is granulated type. 5. In dermis YST group has showed less MAC-1, IL-1 , $IL-2R-\;{\alpha}$ G, ICAM-1 and VCAM-1 than ACD group. 6. The distribution of apoptotic cells has appeared littler in YST group than in ACD 7. Among signal molecule of apoptosis Bcl-2 has distributed more in YST group than ACD group and Bax and Fas has distributed less in YST group than ACD group.

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.

Objective : This study was performed to investigate the effects of Sophorae Radix and Coptidis Rhizoma-iontophoresis in allergic contact dermatitis. Methods : Contact hypersensitivity assay, video microscope, melanin-erythema levels, pH levels, hydration levels, WBC count, RBC count, neutrophil ratio, lymphocyte ratio and total IgE levels were measured. Results : At contact hypersensitivity assay, the right ear swellings in Sophorae Radix and Coptidis Rhizoma-iontophoresis group were decreased compared with control group, but have no statistical significance. At observation of skin morphologic change, many papules were seen in control group and keratins were seen in Sophorae Radix-iontophoresis group. At melanin levels, Sophorae Radix and Coptidis Rhizoma-iontophoresis groups showed no significant difference compared with control group. At pH levels, Sophorae Radix-iontophoresis group showed significant decreased with control group. At hydration levels, Sophorae Radix and Coptidis Rhizoma-iontophoreses groups showed to significant difference compared with control group. WBC count, RBC count and neutrophil ratio were significantly increased in Sophorae Radix and Coptidis Rhizoma-iontophoresis group compared with control group. Lymphocyte ratio and total IgE levels were significantly decreased in Sophorae Radix and Coptidis Rhizoma-iontophoresis groups compared with control group. At morphology of skin, inflammation was decreased and the thickness of epidermis was well preserved in Sophorae Radix and Coptidis Rhizoma-iontophoresis group. Conclusion : Sophorae Radix and Coptidis Rhizoma-iontophoresis had some anti-allergy, anti-inflammatory effects on allergic contact dermatitis, but had no effects on melanin-erythema levels, pH levels and hydration levels of skin.

Experimental drug was applied to a white male mouse taken ill with allergic contact dermatitis to investigate the effects of Yanghyulsamultanggamibang. 1. In case of skin moisture, when it was checked 72 hours later, there showed up meaningful differences among the normal, control, and sample groups. Especially, the moisture increased more noticeably in the sample group than in the control group. 2. With regards to RBC count in blood, it increased more in the control and sample groups than in the normal group when it was checked both in 24 hours and 72 hours. When it was checked in 48 hours, the number of RBC in the sample group increased the most, and the count in the control group increased more than in the normal group. 3. About the neutrophil rate in WBC count, it increased meaningfully more both on the control and sample groups than in the normal group in 24 hours. When the rate was checked in 48 hours, it increased the most in the sample group, and it increased more in the control group than in the normal group. When in checked72 hours later, it increased substantially more in the control group than both the sample and normal group. 4. As of the lymphocyte rate in WBC count, when measured in 24 hours, it increased in the normal group than in the control and sample groups. In 48 hours, it increased the most in the normal group, and it increased meaningfully more in the control group than in the sample group. 5. Regarding the total IgE, when measured 24 hours later, it increased noticeably more in the normal group than in the control and sample groups. In 48 hours, there showed up substantial differences among the normal, control and sample groups. In particular, it increased meaningfully more in the control group than in the sample group. 6. When the sample of skin tissue was examined, the corneal layer restoration increased more in the sample group than in the normal group. The above-mentioned results prove that Yanghyulsamultanggamibang can be taken when allergic contact dermatitis develops on the skin. Long-term observation afterward is also advised.
