Superselective embolization, which enables vital vessels to be protected, while embolizing feeding vessels to the nidus only, has been popularized by Serbinenko in 1971 and there after it has beem used in the treatment of arteriovenous malformation(AVM) mainly for two purposes;first, as a preoperative adjunct to decrease vascularity prior to excision and second, as the principal mode of therapy in unresectable AVM`s. A 23-year-old male was presented with a purple-colored nodule o? 4㎝ in diameter on the left cheek. Angiography revealed an AVM supplied with the oranches of the facial, transverse facial and maxillary arteries. Polyvinyl alcohol, a nonabsorbable permanent solid embolic material, was used to occlude the branches to the nidus, and after the procedure the angiogram demonstrated greatly reduced blood supply to the nidus of the tumor. After a month of the embolization, the tumor decreased considerably in size with the improvement of color.

N/A The Effect on the Recovery of Epidermal Langerhans Cells in C3H Mice after Single and Fractionated Exposure of Ultraviolet B Irradiation Sang-Wahn Koo, M.D., Seung Kyung Hann, M.D., Yoon-Kee Park, M.D., Moo Yon Cho, M.D. Department of Dermatology, Yonsei University College of Medicine Seoul, Korea The study was undertaken to see the recovery in epidermal Langerhans cells in relation to time after UVB irradiation through different amounts and ways of exposure in C3H mice. We irradiated the ears of C3H mice with UVB 200mJ/㎤ and 400mJ/㎤ in a single dose at one time and 5 fractionated doses for 5 days and 10 fractionated doses for 10 days and performed biopsies on the ears of the control and experimental groups after, 2, 7, 14, 21 days of irradiation and stained them by the immunoperoxidase method. The results are summarized as follows. 1. A more significant decrease in the number of Ia-positive epidermal Langerhans cells was observed in single-dose-exposed group than fractionated-dose-exposed groups on the second day of irradiation. 2. On the seventh day of exposure, the number of the Ia-positive epidermal cells in single-dose-exposed group returned to normal, but in fractionated-dose-exposed groups the number of Langerhans cells decreased most remarkably. 3. In fractionated-dose-exposed groups, the number of Langerhans cells returned to normal on the 14th or 21st day of expposure. (Kor J Dermatol 29(4) : 459-465, 1991)
