Recently radiation and radioisotope are being used widely in many fields such as medicine and industry. But only a few papers were reported about the radio dermatitis due to industrial use of radiation. Authors experienced 4 cases of occupational radiodermatitis due to Ir-192 occur red during the radioisotope traspierce test. All 4 patients noticed painful swelling, erythema, and bullae on their fingers or palms 1-2 weeks after exposure. All laboratory tests to detect ystemic effects of radiation were normal. Three patients recovered after treatment with systemic and topical corticosteroid and emollient cream for 2-4 weeks. But one patient suffered from complication of fibrosis and recurrent cellulitis on his fingers. We discussed about the working situation of our patients and reviewed the literatures about the radiodermatitis.

We are calling the erupting ground water as drug water or mineral water in Korea and thinking those water and food making water. Authors tried to investigate the evidence of contamination by user on the 10 erupting ground water and gained following results: 1. All of the mineral waters on 10 area in Seoul were unfittable to drinking water standard. 2. In the view of the bacteriology 80% were contaminated by coliform group. 3. The highest value of the free carbon dioxide contents were 652.96 ppm at Sam Sun Mineral Water.

BACKGROUND: During the last few years, the in vivo study of the physiological parameters of the skin by non-invasive methods has been considerably developed. So far, there have been some reports on the skin characteristics only in parts, but there has not been any criteria to classify those of normal subjects. OBJECTIVE: The aim of the present study was to investigate the skin characteristics of healthy Korean subjects according to sex and sites using non-invasive methods. METHODS: To determine normal levels of sebum, skin hydration, transepidermal water loss (TEWL), skin elasticity and skin color according to sex, 163 subjects (male; 124, female; 39) were used to investigate 5 different anatomical sites. 6 different instruments were used: The Sebummeter SM 410, Corneometer CM 820, Evaporimeter EP1, Cutometer SEM 474, Chromameter CR-121, and Mexameter MX 16, for evaluating sebum excretion rate, capacitance, TEWL, mechanical property and skin color respectively. RESULTS: Differences were noticed depending on the anatomical sites and sex. Most of the measuring parameters were significantly different according to sites and sex. The values of sebum levels, capacitance and TEWL were higher in the males on the cheek, forehead and crows foot, whereas in the females, higher values were observed on the dorsum of the hand. The skin elasticity varied considerably among the nine-parameters but, for the elastic ratio (R2, R5), the females showed significantly higher values than the males in all sites except the forehead. Skin lightness (L* value) was higher in the females, whereas the males showed lugher values in the category of redness (a* value) and yellowness (b* value). The values of the eqrthema index (EI) and melanin index (MI) were also higher in the males on all sites. Correlations between the skin parameters mentioned above were calculated. A negative, correlation between capacitance and TEWL was observed only on the cheek (male/female, r =-0.2/ r =-0.4, p<0.05). The L* value correlated negatively with MI. Mioreover the values between a* and El also showed sipificant correlations in the male (cheek and dorsum of hand, y =0.2, forehead and crows foot, r =0.3, p<0.05). There were considerably significant correlations between the visual pigmentation score and instrumental skin parameters in the males (visual pigmentation score vs. L* value measured by Chromameter ; cheek/crows foot, r = -0.3/y =-0.4, visual pigmentation score vs. MI by Mexameter ; cheek/crows foot, r =0.2/ r =0.4, viisual winkle score vs. sebum excretion rate measured by Sebumeter ; cheek, r=0.2, visual winkle score vs. elasticity parameters measured by Cutometer ; cheek, R2/R5/R7, r =-0.3/ r =-0.2/ r =-0.3, p<0.05). CONCLUSION: Skin physiological parameters can be evaluated by non-invasive skin bioengineering methods which show quantitative modifications in physiological conditions in relation to sites and sex.

Two cases of malignant histiocytosis, in which skin involvement was a prominent finding at initial clinical presentation, are reported. 1nteresting histopathologic findings, including Langerhans granule in one case and numerous eosinophils in another, were observed. In one case remission was achieved with BACOP chemotherapy (Bleomycin, Adriamycin, Cyclophosphamide, Vincristine, and Prednisone). In the other case, the patient died nine months after the onset of the disease without any treatment.

Yonsei University College of Medicine, Seoul, Korea Maffucci's syndrome is characterized by dysccondroplasia with hemangiomata. Since Angelo Maffucci (1881) first described this entity, 105 cases and some more were reported in the literature till 1976. We recently observed a patient suffering from this disorder. The patient is 21 year-old girl, who has multiple hemangiomes on her right foot, right buttock, left wrist and enchondromas on both proximal phalanx, distal phalanx of both great toes and proximal, middle phalanx of right second toe. The disease started at age of 11 and these lesions grew rapidly last 3 years. The diagnosis was based on clinical, radiological and histological findings. Because of its rarity, we report it with brief review of literature.
