Since the foundation of Korean Contact Dermatitis Resear Group in 1980, many reports related to contact dermatitiis have been published. In this articl, 94 Korean references related to epidemiology and clinical aspect of contact dermatitis which have been published for the past 2 decades were reviewcied apers about medicaments were mos 1 equent(53) and, plants and animals(25), occupation(33), cosmetics(23), metals(19) loere in order of frequency. lhe general incidences of contact dermatitis were 5.3% 13.5% in the general out-patients. The main allergens which showed high positive rates in rovin. patch tests were a little different according to the different authors. In common allergens reckel sulfate and cobalt chloride showed increasing tendencies, while ammoniated mercury, first alldehyde, paraphenylene diamine and rubber chemicals showed decreasing tendendies. Potassiun a chromate, neomycin sulfate, and fragrance related allergens which are also commonly encountred showed variable positive rates according to the different authors. In MOHL indices less occuational and few leg ulcer cases have been observed. Obtaining informations are the key point of publication becteria, there have been more aborted studies which were presented at the annual contact dermatit ymposia in Korea, however not published.

Although hepatitis B virus is usually transmitted parenterally, many cases of in fection occur in which overt parenteral contact with the virus cannot be shown. Skin is cansidered to be one route of it and there have been a few related reports recently. As Korea is one of the endemic areas of hepatitis B virus infection, I have checked HBsAg,Anti-HBs, Anti-HBc by radioimmunoassay in patients with hand eczerna to confirm other authors recent report which suggested hand skin lesion is one of the risk factors of hepatitis B virus infection. Total 41 patients were included in this study and all patients were female except one. The study results were as follows. The total prevalence rate of HBsAg was 4, 9% which is not significant different from the control. 2 The total prevalence rate kers including HBsAg was control. of the patients showed positive for one or more markers 5g 5%, which was not significant different from the contorl.

Translation of terminology into Korean in the field of medicine has been one of the important tasks for the last several decades in Korea. Translation of medical terminology is deeply indebted to the Japanese scholars and direct adaptation of their work by the Korean scholars was the main trend since long time ago. This is because we share Chinese characters and the grammar structure. Although some modification and addition of new translation which is more suitable for the Korean language system has been tried in different aspects in the past editions of English-Korean medical terminology books, extensive works has been performed for the 4th edition which was published by the Korean Medical Association in 2001. The Korean Dermatological Association published the first editon of dermatology terminology book in 1983 and the 2nd edition in 1993. Many of them have been adapted in the 4th edition by the Korean Medical Association. However, many changes are noticed representing new trials with innovative ideas. This special article covers some changes of dermatological terminology between the old and new editions of terminology book published by the Korean Medical Association. Major examples are summarized in several tables.

Fifty-five patients completed a questionaire to assess disability caused by atopic dermatitis. The eleven most relevant questions were identified and an Atopic Dermatitis Disability Index (ADDI) calculated. The index correlated with the clinical severity score (rs=0.273, 0.01 <0.05). The index may be used as a simple repeatable record of disability caused by atopic dermatitis and may potentially aid management decisions.

The effect of an allergic contact dermatitis on the irritant was studied using DNCB(2. 5% in acetone) as the sensitizing agent and sodium lauryl sulfate of various concentrations (0. 5, 1. 0, 2. 0% in Vaseline) as the irritant. Three groups of 30 albino Hartley strain female guinea pigs weighing between 350 g and 500 g were used. The results were as follows: 1. The animals which were sensitized with DNCB were shown to be significantly(p<0.05) more irritable than control animals. 2. The animals which were sensitized and challenged with DNCB were shown to be significantly(p<0. 05) more irritable than control and sensitized animals. These data suggest that allergic contact sensitivity as well as allergic contact dermatitis lower the threshold to a nonspecific irritant in guinea pigs, which may explain a mechanism of 'angry back syndrome.

The chrome content of 8 Korean cements and 11 Korean bleaching detrgents was analyzed by the qualitative DPC method and the quantitative atomic absorption spectrophotometry and UV-visible spectrophotometry. In cements, there was no detectable chrome in 1 sample and the range of chrome content in other 7 samples was 1.32 5.29ppm. The qualitative result was welJ. correlated with the quantitative result. In bleaching detergents, there was no detectable chrome in 4 samples and the range of chrome content in other 7 samples was 0.0329 0.362ppm. However, the qualitative result was not correlated with the quantitative result.

BACKGROUND: Factors that regulate hair matrix cell division within the hair follicles and control hair growth cycle have been poorly understood untill now. One of the main.causes seems to be lack of good in vitro models. OBJECTIVE: This study was performed to investigate the hair growth promoting potencies of several agents including individual components of keratinocyte growth media. METHODS: Several agents such as epidermal growth factor, insulin, bovine pituitary extract which were contained in keratinocyte growth media as well as minoxidil and transforming growth factor-α were added to the isolated anagen hair follicles. Measuring the length of hair follicle, thymidine and leucine uptake were used for hair growth parameter. RESULTS: Isolated anagen hair follicles in keratinocyte growth media showed a significant increase in length over 48 hours. [Methyl-³H] thymidine and [U-¹⁴Cl leucine uptake were sustained at basal state as well as over 48 hours and [methyl-³H] thymidine uptake increased in the matrix cells under autoradiography. Insulin with a concentration above 0.5µg/ml and transforming growth factor-α with a concentration above 10ng/ml showed a promoting effect on hair growth. However, other agents did not promote hair growth at all. CONCLUSION: Our in vitro model resembles the in vivo status of hair growth for a limited period of time and we think that normal human hair organ culture may be a useful model for developing hair growth promoting agents in vitro.
