Measurement of 1,4-dioxane in surface water by headspace GC-MS
홍선화,이준배,이수형,임현희,신호상 한국분석과학회 2014 분석과학 Vol.27 No.1
1,4-Dioxane was classified as a Group 2B carcinogen by the International Agency for Research onCancer. The compound was measured in surface water with a headspace gas chromatographic mass spectrometricdetection. A 5 mL water sample was placed in a 10 mL headspace vial and saturated with NaCl, and thesolution was spiked with 1,4-dioxane-d8 as an internal standard and sealed with a cap. Water samples werecollected from twenty-two basins of Gum-River on June and September 2012, respectively. As a result, 1,4-dioxane was detected in the concentration range of 0.49-43.0 μg/L (mean 2.0 μg/L) in the frequency of about30% in surface water samples.
A Spontaneous Uterine Leiomyosarcoma in an Aged Mongolian Gerbil (Meriones unguiculatus)
홍선화,이현아,송제호,김옥진 한국실험동물학회 2009 Laboratory Animal Research Vol.25 No.1
A spontaneous uterine leiomyosarcoma was observed in a 2-year-old female Mongolian gerbil (Meriones unguiculatus). Postmortem examination revealed that the left horn of the uterus was enlarged and nodular shaped. The masses were white, smooth, and glistened at the cut surfaces. Histologically, the pedunculated masses were continuous with the myometrium, which were composed of closely packed sheets of spindle cells embedded in richly vascularized stroma and covered by a discontinuous endometrial epithelium. A variably abundant clear to collagenous matrix separated the neoplastic cells, which had scant to moderate, fibrillar, frequently vacuolated eosinophilic cytoplasm with indistinct borders. The nuclei of these cells were irregularly round to oval with blunt ends, stippled chromatin and indistinct nucleoli. There was moderate nuclear and cellular pleomorphism, with pleomorphic cells that were more abundant in the larger masses. A few lymphocytes, plasma cells, macrophages, and hemosiderophages were scattered among the spindle cells. Several macrophages that contained darkbrownpigment were also present within the epithelium and superficial portions of the masses. Based on the hitopathological findings, this case was diagnosed as a uterine leiomyosarcoma in a Mongolian gerbil.
Spontaneous Ovarian Mucinous Adenocarcinama in a Mongolian Gerbil (Meriones unguiculatus)
홍선화,이현아,김옥진 한국실험동물학회 2008 Laboratory Animal Research Vol.24 No.4
An ovarian mucinous adenocarcinoma was found in a 5-month-old female Mongolian gerbil (Meriones unguiculatus). The animal was evaluated because of slowly progressive abdominal enlargement. Postmortem examination revealed clear, pale, straw-colored fluid in the peritoneal cavity. The left ovary was very huge size as 2x5x3 cm and nodular shaped. Histologically, the tumor was composed of various sizes of multilocular cystic glands lined by a single layer of mucin-filled epithelium. Each of these cystic glands was surrounded by a large amount of solid fibrous stroma resembling smooth muscle. Also, undifferentiated tumor cells were found frequently. The ovarian surface epithelium showed partial invasiveness into the ovarian cortex, and a transition was observed between the surface epithelium and the mucinous cyst-forming epithelium. On the basis of histopathological findings, this case was diagnosed as an ovarian mucinous adenocarcinoma. To our knowledge, this report may be the first case of mucinous adenocarcinoma in Mongolian gerbil.
