In healthy Korean adult males, 6 hour-MED was 51 2+22.6mJ/cm,24 hour-MED was 67. 5+26. 7mJ/cm, and MMD was 86. 5 t21. 3mJ/cm for UVB irradiation respectively. UVB-MED and UVB-MMD was increased by desoxymethasone, hydrocortisone, and bufexama.c creams. Hydrophilic ointment base increased only 24 hour-MED. For 1 MED of UVB, all test agents inhibited erytherna for 48 hours, For 2 MEDs of UVB, desoxymethasone, bufexamac; and hydrocortisone creams inhibited erythema at 6 hours, while desoxymethasone and hydrophilic ointment base could suppress erythema at: 24. hours after irradiation. However, desoxymethasone was the most effective. Hydrophilic ointment base was efficacious only at 24 hours after irradiation. For 1 MMD of UVB, desoxymethasone, hydrocortisone, and bufexamac creams could reduced the delayed tanning (DT) reaction.

lt is generally beIieved that several chemical mediators such as histamine, kinine, prustaglandin E and lysosomal enzyme are related to the pathogenesis of sunburn, but the exact mechenism of erythema is unknown. Recently, prostaglandins appear to be important mediators of ultraviolet erythema (UV-erythema) and several investigators has reported that the nonsteroidal antiinflammatory druga and corticosteroids supressed UV-erythema by inhibition of prostaglandin synthesis. This study was undertaken to evaluate the effect of topical nonsteroidaI antiinflammatary drugs and corticosteroids on UV-erythema induced by a artificial sunlamp. Nonsteroidal anti-inflammatory drugs (5% Bufexamac cream, 5% Ibuprofen cream, 5% Indomethacin cream) and corticosteroids(0.05% Fluocinonide cream, 0.5% Fluocortolone oint., 1%, Hydrocortisone cream) were applied immediately after 3~4 minimal erythema dose(MED) irradiation on back skin of 40 healthy volunteers and the delayed UV-erythema response was evaluated at 2, 4, 6, 8, 12, 24, 48 and 72 hours after irradiation, respectively. The resulta were as follows; 1) Minimal erythema dose(MED) was noted 4min. (62.5%), 3min. (25.0%), 5min. (22.5%). The averaged MED was 3. 63min. 2, MED has to be increased on site, applied nonsteroid and steroid agents topically, comparing with control site. 3) Blanching effect was detected in all cases of nonsteroid and steroid agents applicated topically, but in control site. 4) Average score in blanching effect was highest in 5% Indomethacin cream among nonsteroid agents(average score-2. 47) and 1% Hydrocortisone cream (average scoro -2. 63) among steroid agents.
