Poly(hydroxyethyl acrylate-co-coumaryl acrylate) as a photo-responsive amphiphile
이주협,김진철 한국공업화학회 2014 Journal of Industrial and Engineering Chemistry Vol.20 No.5
Poly(hydroxyethyl acrylate-co-coumaryl acrylate)s P(HEA-CA)s were prepared as a photo-responsive amphiphile by a free radical polymerization. Their CA residues were readily dimerized under UV light irradiation (365 nm, 400 W). Their interfacial activity increased in proportional to the CA content. P(HEA-CA)s were self-assembled into microspheres in aqueous phase due to their amphiphilicity which were confirmed by TEM. And the mean diameter was higher with higher CA content. In addition, P(HEA-CA)s could emulsify mineral oil in distilled water. The emulsions prepared with higher CA content were more stable in terms of the droplet size change. They could be destabilized by UV light irradiation.

Dinitrochlorobenzene 면역요법에 의한 소아에서의 사마귀 치료
이주협,홍창권,노병인 ( Joo Hyeup Lee,Chang Kwun Hong,Byung In Ro ) 대한피부과학회 1991 대한피부과학회지 Vol.29 No.4
Immunotherapy of Wart with Dinitrochlorobenzene in Children Joo Hyeup Lee,M.D., Chang Kwun Hong,M.D.,Byung In Ro, M.D. Department of Dermatology, College of Medicine, Chung Ang University Seoul, Korea This study was conducted to evaluate the thrapeutic effect of dinitrochlorobenzene (DNCB) immunotherapy on warts in children. Thirty nine cases of warts were studied in 28 children who visited the Department of Dermatology, College of Medicine, Chung Ang University from January 1989 to June 1990. The type and number of lesions were as follows : periungual warts(17), verruca vulgaris(14), palmoplantar wart(5), and verruca plana juvenilis(3). The jesion were challenged with 0.05% DNCB in weekly intervals after sensitization with 1% DNCB. The results were summarized as follows 1. Sex ratio of patients was 1:1(14 of male, 14 of emale) and mean age was 10.5 year old. 2. Twenty of all 39 cases(51%) were cured. 3. The highest cure rate was achieved for palmoplantar warts(80%), verruca plana juvenilis(67%), verruca vulgaris(50%). The worst outcome occured with periungual wart(41%). 4. Warts of short duration showed higher cure rates than those of long duration. 5. The number of DNCB challenges until cure for the lesion was 5.5 times for palmoplantar wat;5.4 times for periungual wart;5 times for verruca vulgaris;2 times for verruca plana juvenilis. The mean number of DNCB challenge was 4.5. (Kor J Dermatol 29(4) : 500-505, 1991)
