4.Effect of Repeated Ultraviolet Irradiation on Epidermal Melanocyte of the Expossed and Shielded Ear in C57BL Mice.
Korean Journal of Dermatology 1988;26(3):283-291
In this experiment 40 adult male C57BL mice were used. The one ear of each animal was irradiated with high pressure mercury lamp (Burdick'UV-800) and the other ear was covered with nontransparent tape. Using split epidermal sheets treated with DOPA solution, a quatitiative study of epidermal melanocyte was carried out from the exposed and the shielded ear continuously on every second day during 14 daily exposures to 100 mJ/cm of UVB. The results were as follows : 1. Repeated radiation with ultraviolet light elicited a significant increase in population of melanocytes and the possible mechanism is a direct replication of the functioning melanocytes. 2. UVB irradiation induced increase in the number of epidermal melanocytes in covered ear as well as in irradiated ear. It is suggested that the population increase in the shielded skin is initiated by one or more systemic factors originating from the UVB irradiated skin.

8.A Case of Guttate Morphea with Secondary Cutaneous Mucinosis.
Korean Journal of Dermatology 1997;35(1):165-168
The cutaneous mucinose are a group of connective disorders characterized by the deposition of mucin in the dermis. Thc disease may be a primary (metabolic) or secondary (catabolic). Secondary mucinosis is common in lupus erythematosus and dermatomyositis but rare in morphea. We report a case of guttate morphea with secondary cutaneous mucinosis.

9.A Comparison of UVB-induced Minimal Erythema Dose ( MED ) s to the Skin of the Back and Extremities in Young Adult Koreans.
Korean Journal of Dermatology 1998;36(2):261-265
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).
