tisue disease of dog and cat, resembling Ehlers-Danlos syndrome (EDS) in man. EDS is characterizedby loose, hyperextensible and, fragile skin, it is attributed to mutations in connective tisue gene. Thesemutations cause defects in type I or II collagen synthesis and as a result lack of strength or elasticityto skin, joint, ligament and vessels. EDS-affected animals often experience subcutaneous hematomas thathave long bleeding times. The 4-years old male Yorkshire terrier was evaluated because of subcutaneoushematoma after stifle surgery. Clinical examination revealed a thin and hyperextensible skin and jointlaxity. The degree of skin extensibility index was 23.4%, marked skin stretchy. Clinical diagnosis wasconfirmed by histophathological examination of a skin biopsy revealing reduced packing density ofcollagen fiber of skin.

This clinical research was conducted to test patients with Atopic Dermatitis by external application with Hwangryeonhaedok-Tang in cosmetics. We gave scores to 31 patients who visited the Dept. of Oriental Medical Opthalmology & Otolaryngology & Dermatology of Semyung University Jecheon Oriental Medical Hospital from May 15th, 2008 to June 26th. Fifteen patients were treated with the ointment that contain Hwangryeonhaedok-Tang (experimental group) and sixteen patients were treated with normal ointment that doesn't have Hwangryeonhaedok-Tang (control group) for 4 weeks. We observed change of total IgE, eosinophil count, Skin Temperature, Transepidermal Water Loss(TEWL), Skin Hydration and Skin pH. Also Clinical Index of Atopic Dermatitis(SCORAD Index) and global assesment of efficacy were used to evaluate the effects of Hwangryeonhaedok-Tang. Statistical analysis was performed by using frequency analysis and descriptive analysis. Statistical significance was achieved if the probability was less than 5%(p<0.05). After 4 weeks of external application treatment, SCORAD Index in experimental group was significant statistically decreased compared with control group. After 4 weeks of external application treatment, total IgE of both groups were decreased and eosinophil count in control group was decreased but experimental group was unstatistically decreased. Unstatistically, both groups didn't showed significant effect on Skin Temperature. Transepidermal Water Loss(TEWL) in both groups were increased but experimental group was significant decreased compared with control group. Skin Hydration in experimental group was significant statistically increased compared with control group. Statistically, both groups didn't showed significant effect on Skin pH. Only experimental group showed little increase. After 4 weeks of external application treatment, experimental group showed significant effect on global assesment of efficacy. Considering the above results, we can speculate that cosmetics with Hwangryeonhaedok-Tang has some therapeutical effects in mitigating the symptoms of Atopic Dermatitis.

In order to evaluate the efficacy of SHT against atopic dermatitis (AD), various immune related cytokines as well as histological comparison were performed in animal models, and the results are described. Clinical skin index of the SHT treated group decreased significantly in weeks 11 and 13, compared to the control group. Also, CD4+ immune cell ratio in the dorsal skin was significantly decreased to 69%, and both epidermal and dermal skin thickness was decreased. Serum IL-4, IL-5, IL-6, IL-13, and TNF-${\alpha}$, which are all important markers of inflammation, were decreased to 64%, 44%, 87%, 48%, and 45%, respectively. The expression of histamine, a chemical transmitter increasingly released during the progression of inflammation, was significantly decreased to 47%. The production of IgE immunoglobulin was significantly decreased to 16% compared to the control group. In conclusion, SHT pacifies the activation of T cells, leading to suppression of both Th2 cytokine overexpression and infiltration of immune cells into skin. As a result, relative thinning of both epidermis and dermis were observed. With the results obtained from in vitro studies, the immune modulatory effect of SHT in AD animal models was experimentally demonstrated. This study should provide solid information to construct EBM and for clinical practice.

In this paper, we introduce a digital cross-polarization and fluorescent color imaging system for quantitative evaluation of skin lesions. We describe the characterization of the imaging systems and the quantitative image analysis methods to show the feasibility for quantitative evaluation of skin lesions. The polarization color image was used to compute erythema and melanin index image which are useful for quantitative evaluation of pigmentation and vascular skin lesions, respectively. The fluorescent color image was used to quantitatively evaluate "sebum" and "vitiligo". In quantitative evaluation of various skin lesions, we confirmed the clinical efficacy of the imaging systems for dermatological applications. Finally, we sure that the imaging systems can be utilized as important assistant tools for the evaluation of skin lesions by providing reproducible quantitative result for widely distributed skin lesions.

Objectives : The purpose of this study is to investigate the effect of Gupoongjeseuptang (GPJST) on atopic dermatitis by in vivo experiment using NC/Nga atopic dermatitis mouse, which has histological and clinical similarities to the atopic dermatitis of human. Methods : To investigate the effect of GPJST on atopic dermatifis, we evaluated atopic dermatitis-like skin lesions by clinical skin index and analyzed immunological parameters in peripheral blood mononuclear cells (PBMCs), splenocytes, draining lymph node (DLN) and performed skin histology in ears and dorsal skin of atopic dermatitis-like skin NC/Nga mouse in vivo. Results : In vivo, clinical skin severity score were significantly lower in GPJST group than control group. IgE, IL-6, $TNF-{\alpha}$, IgG1, IgM, IgG2a and IgG2b levels in serum decreased remarkably in GPJST group than control group. Also, total absolute number of $CD3^+CD69^+$, and $CCR3^+$ cells recovered as normal in PBMCs and $CD3^+$, $CD3^+CD69^+$ decreased significantly compared with control group in isolated DLN from NC/Nga mouse and total absolute number of $CD11b^+Gr-1^+$, $CCR3^+CD3^+$ in dorsal skin of NC/Nga mouse decreased by GPJST. We analyzed ear and neck-back skin after biopsy and dyeing by hematoxyline/eosin (H&E) and toluidine staining (mast cells marker) and obtained results that GPJST are very effective to histological symptoms (dermal and epidermal thickening, hyperkeratosis and inflammatory cell (CD4, $CCR3^+$) infiltration). Conclusions : This study demonstrates immunological activity of GPJST on atopic dermatitis-like model mice.

The need for the study of the revealing Sasang constitution at scientific term is increasing as the application of this discipline to the patient produces more accurate result. To obtain scientific evidence of Sasang constitution, it is crucial to analyze accumulated clinical information and associate them to the biological indices that may classify Sasang constitution. Thus, the analysis of clinical information is the most important stepping stone to go toward to the stage of developing model and decision support system (DSS) for classifying Sasang constitution. This study is a preliminary analysis of 1,109 samples collected with 171 clinical indices. To find meaningful clinical indices for classifying Sasang constitutional medicine, we applied decision tree model for them. The skin of 66.5% within whole Taeeumin is thick and non feeble. In the case of 69.8% within whole Soyangin, the skin is non feeble and slippery. In the case of 64.4% within whole Soeumin. they have feeble skin. Therefore, the property of skin can be suggested to be more important than any other index for the classification of Sasang constitution.
