Lymphangiomas are congenital malformations that occur most commonly in the head, neck or axilla and 80-90% of lesions are detected by the age of two years. Cystic lymphangioma of the breast in a 37-year-old woman ; it showed typical well-defined tubular and nodular opacity on mammogram, a multilocular septated anechoic mass on ultrasonogram, and low and high signal intensity on T1- and T2-weighted MR images, respectively. These findings before surgery indicated cystic lymphangioma.

BACKGROUND: Nonalcoholic fatty liver disease (NAFLD) is known to be associated with obesity, type 2 diabetes, and dyslipidemia and highly related to metabolic syndrome. The purpose of this study was to examine NAFLD as a risk factor for cardiovascular disease using the Framingham risk score and carotid intima media thickness. METHODS: We examined 189 Korean adults older than 20 years who participated in a health screening test and had both carotid and abdominal ultrasounds. Patients with viral hepatitis and history of cardiovascular disease and alcohol consumption (>20 g/day) were excluded. We compared clinical characteristics, the Framingham risk scores, and carotid intima media thickness according to the presence of nonalcoholic fatty liver disease. RESULTS: Framingham risk scores and the estimated 10-year risk for coronary heart disease were higher in subjects with NAFLD (11.5+/-4.7 vs 10.2+/-4.3 P=0.04, 8.7+/-7.3% vs 4.9+/-5.0% P<0.001). Carotid intima media thickness was higher in subjects with NAFLD (0.72+/-0.18 mm) compared to the controls (0.63+/-0.15 mm) (P<0.001). This result persisted significantly after adjusting for age, sex, and the 5 components of metabolic syndrome. Multiple logistic regression analysis showed that the presence of NAFLD (odds ratio [OR], 2.95; 95% confidence interval [CI], 1.495-5.812) and triglyceride level (OR, 2.06; 95% CI, 1.041-4.066) were independently related with carotid atherosclerosis. CONCLUSIONS: These results suggest that NAFLD is a risk factor for cardiovascular disease. Physicians should be mindful of this association when seeing patients with NAFLD.

PURPOSE: To analyze the characteristics of CT and MRI findings of facial nerve schwannoma in ten patients. MATERIALS AND METHODS: Ten patients with pathologically confirmed facial nerve schwannoma, underwent physical and radiologic examination. The latter involved MRI in all ten and CT scanning in six. We analyzed the location (epicenter), extent and number of involved segments of tumors, tumor morphology, and changes in adjacent bony structures. RESULTS: The major symptoms of facial nerve schwannoma were facial nerve paralysis in seven cases and hearing loss in six. Epicenters were detected at the intraparotid portion in five cases, the intracanalicular portion in two, the cisternal portion in one, and the intratemporal portion in two. The segment most frequently involved was the mastoid (n=6), followed by the parotid (n=5), intracanalicular (n=4), cisternal (n=2), the labyrinthine/geniculate ganglion (n=2) and the tympanic segment (n=1). Tumors affected two segments of the facial nerve in eight cases, only one segment in one, and four continuous segments in one. Morphologically, tumors were ice-cream cone shaped in the cisternal segment tumor (1/1), cone shaped in intracanalicular tumors (2/2), oval shaped in geniculate ganglion tumors (1/1), club shaped in intraparotid tumors (5/5) and bead shaped in the diffuse-type tumor (1/1). Changes in adjacent bony structures involved widening of the stylomastoid foramen in intraparotid tumors (5/5), widening of the internal auditary canal in intracanalicular and cisternal tumors (3/3), bony erosion of the geniculate fossa in geniculate ganglion tumors (2/2), and widening of the facial nerve canal in intratemporal and intraparotid tumors (6/6). CONCLUSION: The characteristic location, shape and change in adjacent bony structures revealed by facial schwannomas on CT and MR examination lead to correct diagnosis.

Epithelioid hemangioendothelioma(EH) is a rare vascular tumor of low-grade malignancy. It was previously described as intravascular bronchioloalveolar tumor (IVBAT). But electron microscopic study and immunohistochemical staining results have proved endothelial origin. Patients are usually asymptomatic and the tumors are found incidentally on routine chest X-rays. Most patients show a slowly progressive clinical course, even though some patients occasionally die as results of respiratory failure or extrathoracic complications. Confirmative diagnosis is made through thoracoscopic or open-lung biopsy. There is still no effective therapeutic modality for pulmonary EH. We have experienced a 55-year-old woman whose simple chest x-ray film revealed bilateral multiple small nodules. The nodules were histopathologically and immunohistochemically diagnosed as primary epithelioid hemangioendothelioma of the lung. The possibility of metastatic disease was excluded thorough clinical, laboratory and radiological studies. Comparison of radiographic chest film taken 3 years ago showed no significant progression of the pulmonary nodular lesions. Conservative management was instituted and careful 4 months follow-up showed no significant changes.

BACKGROUND: The cyclin D1 gene is one of the most frequently amplified chromosomal regions(11ql3) in human carcinomas. In laryngeal and head and neck carcinomas, its overexpression has been shown to be associated with advanced local invasion and presence of lymph node metastases. Cyclin D1 may therefore play a key role in cell growth regulation and tumorigenesis. Lung cancer is a worldwide problem and in many contries it is the most lethal malignancy. As relapse is frequent after resection of early stage non-small cell lung cancer, there is an urgent need to define prognostic factors. PURPOSE: This study was undertaken to evaluate the prognostic value of the cyclin D1, that is one the G1 cyclins which control cell cycle progression by allowing G1 to S phase transition, on the patients in radically resected non-small cell lung cancer. METHOD: Total Si cases of formalin-fixed paraffin-embedded blocks from resected primary non-small cell 11mg cancer from January 1., 1983 to July 31, 1995 at Hanyang University Hospital were available for both clinical follow-up and immunohistochemical staining using monoclonal antibodies for cyclin D1. RESULTS: The histologic classification of the tumor was based on WHO criteria, and the specimens included 45 squamous cell carcinomas, 25 adenocarcinomas and 11 large cell carcinomas. Cyclin D1 overexpression was noted in 26 cases of 81 cases tested (30.9%). Cyclin D1 expression was not significantly associated with cell types of the tumor, pathological staging and the size of the tumor. But cyclin D1 overexpression was significantly correlated with positive lymph node metastasis(p=0.035). The mean survival duration was 22.76+/-3.50 months in cyclin D1 positive group and 45.38 +/- 5.64 months in cyclin D1 negative group. There was a nearly significant difference in overall survival Between cyclin D1 positive and negative groups(p=0.0515) in radically resected non-small cell lung cancer. CONCLUISON: Based on this study, cyclin D1 overexpressiom appears at important poor prognostic indicator in non-small cell lung cancer and may have diagnostic and prognostic importance in the treatment of resectable non-small cell lung cancer.

OBJECTIVE: This study was to establish a reproducible differentiation system from the parthenogenetic mouse embryonic stem (P-mES02) cells into functional cardiomyocytes like as in vitro fertilization mouse embryonic stem (mES01) cells. MATERIALS AND METHODS: To induce differentiation, P-mES02 cells were dissociated and aggregated in suspension culture environment for embryoid (EB) formation. For differentiation into cardiomyocytes, day 4 EBs were treated with 0.75% dimethyl sulfoxide (DMSO) for another 4 days (4-/4+) and then were plated onto gelatin-coated dish. Cultured cells were observed daily using an inverted light microscope to determine the day of contraction onset and total duration of continuous contractile activity for each contracting focus. This frequency was compared with the results of DMSO not treated P-mES02 group (4-/4-) and mES01 groups (4-/4+ or 4-/4-). For confirm the generation of cardiomyocytes, beating cell masses were treated with trypsin-EDTA, dispersed cells were plated onto glass coverslips and incubated for 48 h. Attached cells were fixed using 4% paraformaldehyde and incubated with specific antibodies (Abs) to defect cardiomyocytes (anti-sarcomeric alpha-actinin Ab, 1: 100; anti-cardiac troponin I Ab, 1: 2000) for 1 h. And the cells were finally treated with FITC or TRITC labelled 2nd Abs, respectively, then they were examined under fluorescence microscopy. RESULTS: Rhythmically contracting areas in mES01 or P-mES02 cells were firstly appeared at 9 or 10 days after EBs plating, respectively. The highest cumulative frequency of beating EBs was not different in both treatment groups (mES01 and P-mES02, 4-/4+) with the results of 61.3% at 13 days and 69.8% at 15 days, respectively. Also the contracting duration of individual beating EBs was different from minimal 7 days to maximal 53 days. However, DMSO not treated groups (mES01 and mES02,4-/4-) also had contracting characteristics although their frequency was a few compared to those of DMSO treated groups (6.0% and 4.0%). Cells recovered from the spontaneously contracting areas within EBs in both treated groups were stained positively with muscle specific anti-sarcomeric alpha-actinin Ab and cardiac specific anti-cardiac troponin I Ab. CONCLUSION: This study demonstrated that the P-mES02 cell-derived cardiomyocytes displayed similarly structural properties to mES01 cell-derived cardiomyocytes and that the DMSO treatment enhanced the cardiomyocytes differentiation in vitro.

OBJECTIVE: This study was to compare the characteristics between parthenogenetic mES (P-mES) cells and in vitro fertilization mES cells. MATERIAL AND METHODS: Mouse oocytes were recovered from superovulated 4 wks hybrid F1 (C57BL/6xCBA/N) female mice. For parthenogenetic activation, oocytes were treated with 7% ethanol for 5 min and 5microgram/ml cytochalasin-B for 4 h. For IVF, oocytes were inseminated with epididymal perm of hybrid F1 male mice(1x106/ml). IVF and parthenogenetic embryos were cultured in M16 medium for 4 days. Cell number count of blastocysts in those two groups was taken by differential labelling using propidium iodide (red) and bisbenzimide (blue). To establish ES cells, blastocysts in IVF and parthenogenetic groups were treated by immunosurgery and recovered inner cell mass (ICM) cells were cultured in LIF added ES culture medium. To identity ES cells, the surface markers alkaline phosphatase, SSEA-1, 3, 4 and Oct4 staining were examined in replated ICM colonies. Chromosome numbers in P-mES and mES were checked. Also, in vitro differentiation potential of P-mES and mES was examined. RESULTS: Although the cleavage rate (> or =2-cell) was not different between IVF (76.3%) and parthenogenetic group (67.0%), in vitro development rate was significantly low in parthenogenetic group (24.0%) than IVF group (68.4%) (p<0.05). Cell number count of ICM and total cell in parthenogenetic blastocysts (9.6+/-3.1, 35.1+/-5.2) were significantly lower than those of IVF blastocysts (19.5+/-4.7, 63.2+/-13.0) (p<0.05). Through the serial treatment procedure such as immunosurgery, plating of ICM and colony formation, two ICM colonies in IVF group (mES, 10.0%) and three ICM colonies (P-mES, 42.9%) in parthenogenetic group were able to culture for extended duration (25 and 20 passages, respectively). Using surface markers, alkaline phosphatase, SSEA-1 and Oct4 in P-mES and mES colony were positively stained. The number of chromosome was normal in ES colony from two groups. Also, in vitro neural and cardiac differentiation derived from mES or P-mES cells was confirmed. CONCLUSION: This study suggested that P-mES cells can be successfully established and that those cell lines have similar characteristics to mES cells.
