일부 도시 중년여성을 대상으로 안면부위별 피부상태를 파악하고자 비침습적 측정방법을 이용하여 유 수분, 멜라닌 홍반 정도를 관찰하였고, 주관적으로 자각하는 유 수분 유형을 조사하여 객관적 측정값들과의 관련성을 보고자 하였다. 안면부위별 측정 결과, 수분량은 눈가>이마>볼, 유분량은 이마>눈가>볼 부위 순이었으며, 홍반지수는 이마>볼>눈가, 멜라닌지수는 눈가>이마>볼 부위 순이었다. 객관적 유분 측정값과 주관적으로 자각하는 유분유형은 일치성을 나타내었다. 유분량 홍반지수, 멜라닌지수의 각 측정값들은 유의한 양의 상관관계를 보였다.

In this study, we investigated the effects of onion(Allium cepa L.) peel extraction aplication on UVB-induced damage of mouse skin. The male C57BL/6 weeks mice were divided into three groups; the control group(Con), the UVB irradiated group(UVB) and the group treated with onion peel extract after UVB irradiation(UVB+Onion peel). Onion peel extraction were topically treated after UVB irradiation(800 $mJ/cm^2$) to dorsal skin. We were measured TEWL, melanin value, erythema index and histological of mouse skin. In the TEWL, melanin value and erythema index observation, UVB+onion peel group were decreased then in the UVB group and 120 and 168 hr groups were similar to the control group. In the histological observation, UVB+onion peel group were indicated hyperkeratosis then in the UVB. These results showed that onion peel extract as a topical application may have preventive effect against UVB-induced skin damage. Therefore onion peel extract might be good material for UVB-damage skin care.

Griscelli syndrome type 2 (GS2) is a rare autosomal recessive disease caused by mutations in the RAB27A gene. It is characterized by cutaneous hypopigmentation, immunodeficiency, and hemophagocytic lymphohistiocytosis. We describe 2 brothers who had GS2 with clinically diverse manifestations. The elder brother presented with a purely neurological picture, whereas the younger one presented with fever, pancytopenia, hepatosplenomegaly, and erythema nodosum. Considering that cutaneous hypopigmentation was a common feature between the brothers, genetic analysis for Griscelli syndrome was performed. As the elder sibling had died, mutation analysis was only performed on the younger sibling, which revealed a novel homozygous mutation in the RAB27A gene on chromosome 15 showing a single-base substitution (c.136T>A p.F46I). Both parents were heterozygous for the same mutation. This confirmed the diagnosis of GS2 in the accelerated phase in both siblings. The atypical features of GS2 in these cases are a novel mutation, isolated neurological involvement in one sibling, association with erythema nodosum, and 2 distinct clinical presentations in siblings with the same genetic mutation.

The prophylactic use of phenytoin during and after brain surgery and cranial irradiation is a common measure in brain tumor therapy. Phenytoin has been associated with variety of adverse skin reactions including urticaria, erythroderma, erythema multiforme (EM), Stevens-Johnson syndrome, and toxic epidermal necrolysis. EM associated with phenytoin and cranial radiation therapy (EMPACT) is a rare specific entity among patients with brain tumors receiving radiation therapy while on prophylactic anti-convulsive therapy. Herein we report a 41-year-old female patient with left temporal glial tumor who underwent surgery and then received whole brain radiation therapy and chemotherapy. After 24 days of continous prophylactic phenytoin therapy the patient developed minor skin reactions and 2 days later the patient returned with generalized erythamatous and itchy maculopapuler rash involving neck, chest, face, trunk, extremities. There was significant periorbital and perioral edema. Painful mucosal lesions consisting of oral and platal erosions also occurred and prevented oral intake significantly. Phenytoin was discontinued gradually. Systemic admistration of corticosteroids combined with topical usage of steroids for oral lesions resulted in complete resolution of eruptions in 3 weeks. All cutaneous lesions in patients with phenytoin usage with the radiotherapy must be evoluated with suspicion for EM.

Objectives : The purpose of this paper is to report the effect of Korean medicine treatments on allergic contact dermatitis aggravated after applying steroid ointment. Methods : We treated a 63-year-old woman with allergic contact dermatitis on the both forearm, jaw, neck, chest with Korean medicine. Before Korean medicine treatments she has taken oral steroids and applied steroid ointment for several years to treat dermatitis, but long-tern steroid therapy aggravated her symptoms like skin pruritus, erythema, exudates or edema. After Korean medical treatment for 27 days, we found that the size of erythema was reduced, and symptoms like pruritus, exudates and edema were lost. We recorded pictures of changes on symptoms. Results & Conclusions : The symptoms of allergic contact dermatitis were improved. Erythema, edema, exudate were lost. Thus Korean medicine treatments are effective on allergic contact dermatitis and could be a great alternative to steroid treatment.

구강 점막에 발생하는 동통성 궤양은 다양한 질환에 의해 발생할 수 있다. 구강내 병소가 발생한 후 피부병소가 발생하는 질환 또는 구강과 피부 동시에 병소가 발생하는 질환의 경우, 구강내만 국한하여 검사를 시행하고 피부 병소를 간과할 때는 진단이 어려울 수 있다. 본 증례에서는 구강 및 전신에 발생한 통증성, 미란성 병소가 나타나는 다형홍반 및 Stevens-Johnson syndrome(SJS) 환자를 경험하여 이를 보고하고 피부병소가 동반되는 구강점막 질환에 대해 고찰해 보고자 한다.

다형 홍반은 피부, 구강, 입술 및 생식기 등을 침범하는 급성 피부점막 질환으로 점막 침범 여부에 따라 다형 홍반 minor와 다형 홍반 major로 분류된다. 스티븐스-존슨 증후군과 독성표피괴사용해는 다형 홍반 major에 속하는데, 이들은 증상이 심하고 진행성이며 높은 사망률을 보인다. 코르티코스테로이드는 현재 다형 홍반의 치료제로 사용되고 있다. 저자들은 신증후군을 가진 소아 환자에서 경구 코르티코스테로이드인 데플라자코트를 사용하던 중 발생된 3개의 다형 홍반 증례를 보고하는 바이다.

다형 홍반은 피부 혹은 점막에 영향을 미치는 수포성, 궤양성의 염증성 질환이다. 이는 단순포진 바이러스와 같은 감염이나, 항생제나 진통제와 같은 약물에 의해 유발하는 것으로 알려져 있다. 증상으로는 피부에 과녁모양의 전형적인 병소가 나타나는 것으로 알려져 있으며, 구강 내에 증상이 발현 될 경우, 입술, 볼, 혀에 미란성의 병소가 발현되는 것으로 알려져 있고, 이는 다른 구강내 병소와의 감별을 필요로 한다. 본 증례에서 트리코모나스 감염 또는 메트로니다졸 투여로 인해 유발되었을 것으로 추정되는, 구강에 발생한 다형홍반의 사례를 소개하고, 다형홍반의 진단 및 치료에 대해서 고찰해 보고자 한다.

본 연구에서는 SPF 측정법에 있어서 널리 사용되어온 희석법과 박막법의 문제점에 대해 검토하였으며, 이들의 문제점을 극복하기 위하여 인체를 대상으로한 in vivo평가법과 측정 및 평가 등의 실험조건에 있어서 유사성을 갖는 in vitro평가법을 개발하였다. 이 새로운 in vitro 평가결과는 in vivo 평가결과와 0.93의 높은 상관계수를 나타내었다. 한편 이 in vitro 측정법의 유용성을 더욱 확인하기 위하여 TransporeR tape에 시료를 도포한 후 SPF-290 분석기를 이용한 측정결과와 비교한 결과 SPF20 이하의 시료일 경우 0.95 이상의 높은 상관계수를 얻을 수 있었다. 또한 광량을 일정하게 유지 시키고 광세기를 변화 시켜 홍반의 정도를 조사한 결과, 광세기와 홍반의 정도에는 관련이 없음을 알 수 있었다.

BACKGROUND/OBJECTIVES: The skin is the outermost organ of the human body and plays a protective role against external environmental damages, such as sunlight and pollution, which affect anti-oxidant defenses and skin inflammation, resulting in erythema or skin reddening, immunosuppression, and epidermal DNA damage. MATERIALS/METHODS: The present study aimed to investigate the potential protective effects of red orange complex H extract (ROC) against ultraviolet (UV)-induced skin photoaging in Skh:HR-2 mice. ROC was orally administered at doses of 20, 40, and 80 mg/kg/day for 13 weeks, along with UV irradiation of the mice for 10 weeks. RESULTS: ROC improved UV-induced skin barrier parameters, including erythema, melanin production, transepidermal water loss, elasticity, and wrinkle formation. Notably, ROC inhibited the mRNA expression of pro-inflammatory cytokines (interleukin 6 and tumor necrosis factor α) and melanogenesis. In addition, ROC recovered the UV-induced decrease in the hyaluronic acid and collagen levels by enhancing genes expression. Furthermore, ROC significantly downregulated the protein and mRNA expression of matrix metalloproteinases responsible for collagen degradation. These protective effects of ROC against photoaging are associated with the suppression of UV-induced phosphorylation of c-Jun NH2-terminal kinase and activator protein 1 activation. CONCLUSIONS: Altogether, our findings suggest that the oral administration of ROC exerts potential protective activities against photoaging in UV-irradiated hairless mice.
