Objectives The purpose of this study is to evaluate the effects of Low Level Laser Therapy on Atopic dermatitis symptoms. Methods 19 patients (7 men, 12 women) were involved in this study. The intensity of SCORAD index (Erythema/darkening, Edema/papulation, Oozing/crust, Excoriation, Lichenification/prurigo, Dryness) and the symptom of SCORAD index (Pruritus) in two regions were measured. One region was treated by LLLT, the other region was not treated. Then a comparative study of index score of two regions was analyzed. Results After treatment, there were statistically significant differences in Edema/papulation, Excoriation (p<0.001), Oozing/crust (p<0.01), and Pruritus(p<0.05) index. Conclusions Based on the results, we concluded that LLLT is an effective in the treatment of atopic dermatitis. Also, further controlled studies with clinical cases of appropriate treatment time, wavelength, and intervals are needed.

Objectives : This study was conducted to test patients with Atopic Dermatitis by external application with Gynostemma Pentaphyllum MAKINO in cosmetics. Methods : We gave scores to 59 patients who visited the Dept. of Oriental Medical Opthalmology & Otolaryngology & Dermatology of Daegu Hanny Oriental Medical Center from July 1st, 2005 to December 31th. We checked the clinic index score(extent. intensity : the degree of erythema, induration or papulation, puritus, excorination, lichenification, scaling or dryness, erosion or oozing or weeping. the degree of itching), Eosinophil count and IgE. Results : There are 46 patients we could check by clinic index score, and 44 patients by laboratory. 1. In the 46 cases clinic index score was significantly decreased between the before- and afterexternal application treatment periods(P<0.01). 2. The 46 cases was devided into two types (moist heat type and blood dryness type) by intensity. External application of Gynostemma Pentaphyllum MAKINO in cosmetics did not significant change by two types. 3. In the 44 laboratory cases, the number of eosinophil counts was decreased but the number of IgE was significantly increased. Conclusions : Considering the above results, we have concluded that cosmetics with Gynostemma Pentaphyllum MAKINO have the remedical effect for Atopic Dermatitis.

Psoriasis is an auto-immune skin disease, which is characterized by the excessive generation of plaques on the skin with typically a long-lasting red, itchy and scaly symptoms. Imiquimod, which has been used for the treatment of external genital warts, actinic keratosis, and superficial basal cell carcinoma, induced of psoriasis-like skin disorders with skin erythema and thickness in mice. In the present study, we tried to find the bioactive herbal extract against imiquimod-induced psoriasis-like skin disorder in mice. During the searching of the herbal extract with anti-psoriatic effect, the ethanolic extract of Cnidium officinale ameliorated imiquimod-induced psoriasis-like skin disorder in mice. The morphological evaluation, H&E staining and Psoriasis Area and Severity Index (PASI) score showed that ear and back thickness, and erythema induced by imiquimod were significantly reversed after the treatment of the cream of the ethanolic extract of C. officinale. The overexpressed myeloperoxidase (MPO) and keratin 6A levels were decreased by the treatment of C. officinale cream. Also, $IFN-{\gamma}$, c-fos and $I{\kappa}B-{\alpha}$ mRNA levels, which are related to the progression of psoriasis, were reduced by C. officinale cream. Thus, the ethanolic extract of C. officinale ameliorated psoriasis-like skin disorder induced by imiquimod and might be the therapeutic agent for psoriasis.

The objective of this study was to evaluate the potential use of ginseng leaf as a cosmetic material. In this research, we employed enzymatic treated ginseng leaf by using Ultraflo L to improve the recovery of ginsenosides from the ginseng leaf and studied the biological activities and skin safety of the enzymatic treated ginseng leaf for use as a cosmetic material. The total ginsenoside contents of the non-enzymatic treated ginseng leaf (NEGL) and Ultraflo L treated ginseng leaf (UTGL) were 271 and 406 mg/g, respectively. The level of metabolite ginsenosides (sum of Rg2, Rg3, Rg5, Rk1, compound K, Rh1, Rh2, and F2) was higher in UTGL (93.1 mg) compared to NEGL (62.4 mg) in one gram ginseng leaf extract. The increase in amounts of ginsenoside types in UTGL compared to NEGL was generally 140% to 157%. UTGL exhibited relatively higher 2,2-diphenyl-2-picrylhydrazyl hydrate ($IC_{50}$, 2.8 mg/mL) and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt ($IC_{50}$, 1.6 mg/mL) radical scavenging activities compared to NEGL (4.8 mg/mL and 2.2 mg/mL). The UTGL group showed normalized hydrogen peroxide, lipid peroxidation and visual wrinkling grade induced-UVB exposure. The UTGL did not induce any adverse reactions such as erythema and edema on intact skin sites; however, some guinea pigs treated with UTGL on abraded skin sites showed very slight erythema. The primary irritation index (PII) score of UTGL was 0.05 and it was classified as a practically non-irritating material (PII, 0 to 0.5). In skin sensitization tests with guinea pigs, UTGL had a positive rate of skin sensitization at 40%, and the mean evaluation score was 0.4.

Exposure to the sun, ultraviolet radiation, and oxidative stress are the chief etiologic factors responsible for melasma. The ingredients of Korean red ginseng powder, which include ginsenoside and phenolic compounds, have antioxidative effects and reduce ultraviolet B-induced pigmentation. This study was designed to evaluate the effectiveness and safety of Korean red ginseng powder in patients with melasma. In 25 female patients, 3 g of Korean red ginseng powder was orally administered for a 24 week period. The level of pigmentation and erythema were determined and clinical improvement was evaluated by the melasma area and severity index (MASI), melasma quality of life scale (MELASQoL), and patient- and investigator-rated global improvement scale. After 24 weeks, the MASI score decreased from 8.8 to 5.6, and MELASQoL showed improvement in 91% of patients (p<0.05). The mean level of pigmentation decreased from 184.3 to 159.7 and erythema levels decreased from 253.6 to 216.4 (p<0.05). Additionally, 74% of the patients showed some improvement in both patient- and investigator-rated global improvement scales at week 24. Korean red ginseng powder was well tolerated by most of the patients. In conclusion, Korean red ginseng powder showed good tolerability and beneficial effects in patients with melasma. The use of Korean red ginseng would be counted as a useful adjunctive therapy for patients with melasma.

This study investigated the clinical parameters of atopic dermatitis and evaluated the inhibitory effects of Black currant seed oil for atopic dermatitis by using a Dinitrochlorobenzene(DNCB) induced BALB/c mice model. Five-week-old BALB/c mice were divided into four groups: normal group (N, non-treated), control group (C, atopic dermatitis-induced), positive control group (PC, Tacrolimus ointment-treated against induced atopic dermatitis, PC), experiment group (E, Black currant seed oil-treated against induced atopic dermatitis). After induction of atopic dermatitis by DNCB, the erythema, edema, eschar, and scratching were severely observed. The symptoms of atopic dermatitis were improved after 2 weeks, and almost disappeared after 4 weeks in PC and E group. The increased frequencies of scratching in C group were decreased in PC and E group. Transepidermal water loss, erythema index and serum IgE level were significantly decreased in E and PC compared to that in C after 4 weeks of the treatment. The results indicated that Black currant seed oil can relieve atopic dermatitis symptoms effectively, and may be possibly used as a functional material for suppression of atopic dermatitis.

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.

알러지성 접촉피부염은 T세포와 대식세포가 관여하는 세포매개성 면역반응으로 항원에 노출된 뒤 수 일 후에 증상이 발현되는 지연형 반응으로 특이 T세포의 활성을 통해 다양한 cytokine이 분비되어 항원 유입부위로 염증세포의 유주로 염증이 발생한다. 본 연구에서는 DNCB로 유발한 알러지성 접촉피부염에 대한 아로마 오일 합제의 항염효과를 평가하였다. 아로마 오일 합제는 8일간 적용하였고 실험기간 동안 2일 간격으로 피부 생물리학적 지표를 측정한 후 피부생검을 통해 피부조직을 평가하였다. DNCB 적용 후 피부 생물리학적 지표인 표피경유수분손실, 피부 수화도, 피부 두께 그리고 홍반지수가 증가하였다 (p < 0.05). 피부조직 평가에서 염증세포 침윤과 부종성 변화에 의한 상피두께 증가 및 진피 결합조직의 감소가 특징적으로 나타났다. 또한 진피내 pro-inflammatory cytokine인 TNF-${\alpha}$와 IFN-${\gamma}$ 면역반응세포수 및 표피내 apoptotic change의 지표인 caspase-3와 PARP 면역반응세포의 수가 유의적으로 증가 하였다 (p<0.01). 그러나 아로마 오일 합제 적용후에는 피부 생물리학적 지표 (p<0.05) 및 피부조직의 병리적 변화는 (p<0.01) 기저상태로 회복되었다. 따라서 본 연구를 통해 개에서 DNCB에 의한 알레르기성 접촉피부염 유발 및 아로마 오일 합제의 우수한 항염증 효과를 확인하였고 아로마 오일 합제는 향후 피부염에 대한 치료제로 사용할 수 있을 것으로 기대된다.
