다국어 초록 (Multilingual Abstract)

Background: The erythemal response of the skin to UVB radiation is used as a diagnostic phototest and guideline to phototherapy. Objective : The purpose of this study was to compare the UVB-induced MEDs to the back, arm, and thigh skin Methods: A sunlight fluorescenct lamp(Waldmann UV 7001K) was used as a UVB radiation source. The back, arm, and thigh skin were irradiated with the dose, from 40mJ/cm2 to 180mJ/cm2. The minimal doses for erythema responses to the skin were assessed visually at 24 hours after irradiation Results : MEDs of the back, arm and thigh skin were 92.6 + 17.3mJ/cm2(mean + S.D.), 123.0 + 24.2mJ/cm2, and 126.6+ 28.3mJ/cm2, respectively. The most frequent MED was 100mJ/cm2 for the back skin and 120mJ/cm' for the arm skin and thigh skin. Conclusion : In this study, UVB-induced MEDs to the back, arm, and thigh skin in young adult Koreans were assessed. A significant difference in the MED was found between the back and extremities skin, with a lower value for the back skin(92.6 + 17.3mJ/cm2) than for the arm skin(123.0 + 24.2mJ/cm2) or for the thigh skin(126.6 + 28.3mJ/cm2).
