Ultraviolet radiation of skin leads to a systemic alteratior tkat inhibits the normal pattern of immunologic tumor rejection., suppresses the contact hypersemisivity and transiently alters the morphology and the surface marker characteristics of Langerhans cells. Moreover, Ultraviolet radiation elaborates the ETAF, neuropeptides, proteins, and urocaicacid which may alter immunologic responses. But no other study about the effects of UVB irradiation on the systemic immunologic functions of the macrophages of internal organs was reported. The macrophages of the reticuloendothelial system (RES) play a central role in cell-mediated immunity, because they are involved both in the initiation of responses as antigen-presenting, cells, and in the effector phase as inflammatory, tumoricidal and microbicidal cells. The present study was intended to investigate the effects of UVB irradiation on the immunologic functions of mouse peritoneal macrophages. Normal 6-8-week-old BALB/c mice were exposed at the dose rate of 20mJ/cm and 40mJ/cm of UVB per day, 5 days per weeks for 2 weeks, 4 weeks and 8 weeks. Then the peritoneal macrophages were obtained from the mice and the changes of cell count, chemotactic index, phagocytic index, NBT reduction rate and superoxide (0) production were examined. The results were as follows : 1)the number of mouse peritoneal macrophages was decreased by UVB radiation, 2) the chemotactic index of mouse peritoneal macrophage was not altered by UVB radiation, 3) phagocytic activity of mouse pertoneal macrophage was significsntly decreased by UBV radiation, 4) NBT reduction rate in mouse aeritoneal macrophage after UVB radiation was sinificanily decreased in all experimental group, and 5) Superoxide (0) production in mouse peritoneal macrophage after UVB radiation was decreased in all experimental groups.

BACKGROUND: Alopecia areata is replete with data from studies using variuos therapeutic approaches, none of which is clearly superior to another. OBJECTIVE: This study was designed to evaluate the therapeutic effect of cryotherapy in alopecia areata. METHODS: Thirty three patents with AA(M:13, F:20) well conduted in this study, precluding 3 patients with the moderate and extensive lesions. Cryotherapy using a cotton swab dipped with liquid nitrogen was applied to the involved areas, repeated with 2 times of freeze thaw cycle of two seconds. In 13 cases of AA multiplex, the lesions were divided into two groups, each of which was undertaken cryotherapy and intralesional injection of triamcinolone(3mg/ml) for evaluation of their respeetive effects. The treatment was done weekly method of 1 to 11 times, Th therapeutic response was determined as the regrowth of terminal hairs on the treated area(s) at 12 Weeks. RESULTS: Of the 33 patients with AA, the overall responders were 22(66.7%). There seemed good response rates of 70.0 % in females, 71.4 % in AA multiplex and 72.2 % in third decade as well as 72.4 % in those with lower than 1 year of duration. The remarkable resionse had 3-4 times in treatment numbers. There were no untoward side effects in patients except mild erythema. In the 13 patients treated with both modalities, cryotherapy had a slightly higher esaonse than triamcinolone therapy (69.2% vs 61.5%, p>0.05 by x-test). CONCLUSION: The effect of cryotherapy therapy in AA patients is not less than the intralesional therapy of triamcinolone. In addition, cryotherapy may be recommendec as the new, safe therapeutic modality.
