목적: 모양체종양 형태로 발생한 과립세포종양 1예를 경험하였기에 보고하고자 한다. 증례요약: 42세 여자가 내원 1달 전부터 시작된 우안 시력저하를 주소로 내원하였다. 과거력상 특이 병력 없었고, 세극등검사상 모양 체 고랑내 종괴 소견과 이와 관련된 것으로 보이는 합병성 백내장이 보였다. 모양체종양 및 합병성 백내장에 대해 경공막 모양체종양 절제 생검, 초음파수정체 유화술 및 후방 인공 수정체 삽입술을 시행하였고, 생검 결과 과립세포종양으로 판명되었다. 술 후 6개월간의 경과관찰에서 종양의 재발 소견은 보이지 않았다. 결론: 모양체종양 형태로 발생한 과립세포종양을 조직학적 소견으로 확진하였기에 보고하고자 한다. Purpose: To report a case of a granular cell tumor in the form of cilliary body tumor. Case Summary: A 42-year-old women visited our clinic with blurred vision of the right eye, which began was 1 month earlier ago. Her medical history was unremarkable. Slit-lamp examination revealed a ciliary body tumor and complicated cataract due to a mass lesion. For treatment, an excisional biopsy of the ciliary body tumor and phacoemulsification were performed. The pathologic finding confirmed the diagnosis of a granular cell tumor. There was no evidence of a recurrent lesion of the tumor at the 6-month postoperative follow-up. Conclusions: We confirmed a granular cell tumor in the form of a cilliary body tumor based on pathologic findings.

This research in the degradation of polychlorinated biphenyls(PCB) has focussed on the use of experimental enrichment cultures to obtain PCB-deading communities and identification of PCB-degrading bacteria accor야ng to pure culture. During 180 days, enrichment culture was performed to obtain PCB-degrading bacteria and initial concentration was injected 1.6 ppm,0.7 ppm, respectively. After 180 days of enrichment culture, PCBs was removed 80-87% and 57-71%. Biodegradation of PCBs was studied according to dominated PCB-degrading bacteria. Biodegraddation of PCBs was 80% in initial concentration of PCBs for 20days, enrichment cultured PCB-degrading bacteria was isolated by pure culture and it was verified to Pseudoxanthomonas sp.
