Adult Wilms' tumor, unlike that of childhood, is a rare disease. Microscopically, the tumor is fundamentally characterized by triplastic embryonal renal tumor composed of variable amounts of metanephric blastema and its epithelial and stromal derivatives but rarely a small group of tumors composed virtually entirely of differentiated epithelial derivatives, the abundance of tubular structures. These monomorphous epithelial type of Wilms' tumor tended to have an early onset and benign course. Grossly, classic Wilms' tumor is a solid tumor, but very rarely shows cystic change and may lead to misinterpretation as a polycystic kidney or multicystic nephroma. Here, we reports a case of primary renal tumor, grossly very similar to a multicystic kidney but histologically represent a tubular monomorphous epithelial variant of Wilms' tumor occured in 63 year old male adult.

OBJECTIVE: Sarcoma of uterus is originated from uterine muscles and/or connective tissues and rare and most lethal of all primary uterine tumors. The purpose of this study was to evaluate the clinical outcome of 12 patients diagnosed primary uterine sarcoma at the Department of Obstetrics and Gynecology in Kyungpook National University Hospital between 1984 and 1998 for 15 years. METHODS: After review of chart in twelve patients, data including clinical and histologic findings, treatment and outcome were analysed. RESULTS: The most common histologic finding was leiomyosarcoma(6cases, 50%) and the age of patients ranged 24 to 69 years and the average age was 43.25 years and two patients were nulliparous. The most common sign was abnormal uterine or vaginal bleeding(48%), and pelvic cavity or vaginal mass(16%), pelvic pain(16%), no symptom(16%), in order of frequency. The distribution by FIGO clinical stage was four cases(33%) for stage I, one case (8%) for stageII, one case(8%) for stage III, six cases (50%) for stage N. The nine cases received hysterectomy with or without BSO. Two cases received myomectomy to preserve fertility. The mean follow-up duration was 39.6 months. CONCLUSION: Uterine sarcoma is an uncommon and aggressive tumors with a poor prognosis. Leiomyosarcoma is the most frequent histologic type(50%). Stage I uterine sarcoma with or without adjuvant chemotherapy has better prognosis than other stages.

It is now well-known that the electronic data processing system(EDPS: computer) is very useful for indexing, sorting, verification, and so on. And a few orthopedics in Korea are processing informations with computers for their medical records respeetively. But since there are no established principles on the description of orthopedic diseases, a computer programmer unfamiliar with medical terms is poor in electronic processing for medical records. After processing with an IBM computer for several years, it has come to our attention that we have a need for standardization of the description of orthopedic diseases for EDPS. Based largely on the International Classification of Diseases(ICD-9th), we propose the following: 1. Diseases should be written in English, and whether it be capital letter or small letter does not matter. 2. Description of the disease should be in order of title, region of the body, cause or present status, and side of the body. The sequence may be changed without problem, but only the noun form should be used. It is also recommended that the key words in articles be defined. 3. Abbreviated forms should be avoided. If inevitable, the abbreviation should be used consistently from the first to the 1ast. 4. Connection with other types of medical records such as medical insurance system by registering the code number of the International Classification of Disesaes at the end of the description or on another line.

To examine the association of hypertension with cluster of obesity, abnormal glucose and dyslipidemia in Korean urban population, we conducted this cross-sectional study among 3027 men and 2127 women age 20-85 years who visited a prevention center between May 1991 and June 1995 for a multiphasic health check at St. Mary's Hospital, Seoul. By the self-administered questionnaire, the informations of educational attainments, monthly income, alcohol consumption, cigarette smoking, and physical excercise level were obtained. Height, weight, and blood pressure were measured by a trained nurse. The fasting blood sugar(FBS), total cholesterol, high density lipoprotein (HDL) cholesterol and triglyceride were tested by enzyme method. Low density lipoprotein (LDL) cholesterol was calculated by 'total cholesterol - HDL cholesterol - triglyceride/5'. For testing the differences of cardiovascular risk factors between hypertension and normotension group, t-test and x2 test were performed and for the age adjusted odds ratios of hypertension in persons with obesity, abnormal glucose, and dyslipidemia compared with normal, logistic regression was performed by using SAS pakage programme. The results obtained were as follows: 1. Age, weight, body mass index, blood glucose, total cholesterol, low density lipoprotein, triglyceride of hypertension group in men and women were significantly higher than normotension group, but height and high density lipoprotein of hypertension group only in women significantly lower than normotension group. The frequency of obesity (body mass index > or =25 kg/m2), abnormal glucose (> or = 120 mg/dl), hypercholesterolemia (> or =240 mg/dl), lower HDL cholesterol (<45 mg/dl in women only), higher LDL cholesterol (> or =160mg/dl), and hypertriglyceridemia (> or =250 mg/dl) in hypertension group of men and women were significantly higher than normotension group. 2. Systolic and diastolic blood pressure were negatively correlated with hight, but positively with age, weight, BMI, total cholesterol, LDL cholesterol, and triglyceride in men and women. And BMI was positively correlated with fasting blood sugar, total cholesterol, LDL cholesterol and triglyceride but negatively with HDL cholesterol. 3. The odds ratios of hypertension were as follows in men and women : among persons who were obese compared with those nonobese, 2.53 (95% Confedence Intervals [C.I.] 2.08-3.07) and 2.22 (95%C.I. 1.71-2.87); among persons who were abnormal glucose compared with those normoglycemic, 1.43 (95%C.I 1.13-1.82) and 2.01 (95%C.I 1.36-2.94); and among persons who were dyslipidemia (hypercholesterolemia or lower HDL cholesterol or higher LDL cholesterol or hypertriglyceridemia) compared with those normal lipid, 1.59 (95%C.I 1.30-1.95) and 1.51 (95%C.I 1.16-1.96). After combined more than one risk factor, the odds ratios were increased. Among persons with cluster of obesity, abnormal glucose, and dyslipidemia, the odds ratio of hypertension was 2.25 (95%C.I 1.47-3.37) in men and 3.02 (95%C.I 1.71-5.30) in women. In conclusion, it was suggested that hypertension was associated with cluster of obesity, abnormal glucose, dyslipidemia in this Korean urban population.

Kupffer cells are tissue macrophages (histiocytes) fixed in hepatie sinusoids. Since malignant hepatocytes are the only tumor parencymal cells of the hepatocellular carcinoma, theoretically there are no Kupffer cells within the hepatocellular carcinoma. To clarify whether it is true or not, 12 cases of hepatocellular carcinoma of the trabecular type with some extents of the non-neoplastic surrounding liver were subjected to immunoperoxidase staining for lysozyme and S-100 protein and the results are as follows. 1) Kupffer cells were stained positively by the immunoperoxidase staining for lysozyme but not for S-100 protein, indicating that they are monocyte derived macrophages. 2) Kupffer cells were also present within the hepatocellular carcinoma, but were 2-7 times fewer within the hepatocellular carcinoma than in the non-neoplastic areas (p<0.05). 3) The non-neoplastic hepatic tissue of patients with serum HBsAg shows a tendency to have more kupffer cells than those without HBsAg.

To elucidate the effect of copper on the 3'-methyl-4-dimethylaminoazobenzene(3'-MeDAB) induced hepatic carcinogenesis, Sprague-Dawley rats were divided into 4 groups according to 3'-MeDAB and copper administration: I. noraml control, II. copper only, III. 3'-MeDAB only, IV. 3'-MeDAB plus copper. The animals of groups III and IV were fed experimental diet containing 0.06% 3'-MeDAB. Copper was administrated intraperitoneally in a dose of 0.5 mg, twice a weak. Animals were sacrificed at different intervals. Liver weight, hepatic copper content and gross and microscopical changes of the liver were examined and the cell kinetics of various lesions in the hepatic carcinogenesis was studied by applying the immunohistochemical method for bromodeoxyuridine(BrdU). The hepatic copper content was significantly increased in animals given copper but returned to the normal value after cessation of adminstration. 3'-MeDAB administration caused oval cell proliferation and produced hyperplastic nodules, cholangiofibrosis and carcinoma of the liver. Simultaneous administration of copper did not alter the incidence of 3'-MeDAB induced lesions, except for carcinoma. The liver weight and the size of hepatic nodules and masses were smaller in group IV than in group III. The liver weight as well as the nodularity and the mass formation continued to increase affect cessation of 3'-MeDAB administration. Copper did not affect the BrdU labelling indices of the hepatic lesions induced by 3'-MeDAB. The oval cell proliferation and the BrdU labelling indices of the oval cell and the hyperplastic nodule were decreased, but the incidence of cholangiofibrosis and its BrdU labelling index were still elevated after cessation of 3'MeDAB administration. These findings indicate that copper could delay the developement of 3'-MeDAB induced hepatic lesions, but not suppress, since copper does not stay long enough to accumulate in the rat liver, and that copper could not affect the proliferation of 3'-MeDAB induced hepatic lesions once developed.

It has been clarified that myoepithelial cells contain S-100 protein which is known to be a marker protein of neural tissue. To evaluate the participation of myoepithelial cells in the histogenesis of the salivary gland tumors, normal salivary glands and various salivary gland tumors were stained by immuno-peroxidase method. PAP kits (DAKO Co, USA) for the S-100 protein and the Cytokeratin were used and the following resulting were obtained. Acinic cells of the normal salivery gland were negative for both cytokeratin and S-100 protein. The intercalated duct cells were weakly positive for cytokeratin and S-100 protein. The normal myoepithelial cells scattered around the acini and the intercalated ducts were positive only S-100 protein. In contrast, the striated duct were positive only for cytokeratin. In plemorphic adenoma, the S-100 protein positive cells were found in solid sheets of tumor cells, in chondromyxoid areas and in areas of spindle-cell stroma as well as in the outer layer of the tubular structures. Only the inner lining of the tubules were positive for cytokeratin. In basal cell adenoma, the stromal spindle cells were strongly positive for S-100 protein and the epithelial cells weakly positive. When tubules were present within the epithelial sheets, the inner most lining cells were positive for cytokeratin. The peripheral palisaded tumor cells were negative for both substances. By immunostaining of the adenoid cystic carcinoma, S-100 protein containing cells were found focally scattered independently on the variety of histologies. The lining cells of true cystic structure were positive for cytokeratin. Immunostaining of the mucoepidermoid carcinoma demostrated that the squamous cells and the tubular epithelial cells contained cytokeraitn, whereas only a few intermediate cells were positive for S-100 protein. In Warthin's tumor there were no S-100 protein positive cells, although basally located epithelial cells of the papillae were positive for cytokeratin. These findings suggest that salivary gland tumors other than the Warthin's tumor arise from myoepithelial cells or reserve cells having dual potentiality differentating into myoepithelial and intercalcated duct cells.

PURPOSE: High flow rate (FR) and pressure limit (PL) strategy with time-cycled pressure-limited (TCPL) ventilator is employed routinely in the neonates. Theoretical basis of this strategy is the two-compartment theory that the lung with acute respiratory failure consists of units with different compliance and resistance. But such constant pressure strategy has the risk of ventilator induced lung injury. We compared the ventilatory indices and clinical outcomes of two different strategies, high FR-constant pressure and low FR-constant FR in the ventilator care of the neonates with acute respiratory failure. METHODS: For the neonates born in our hospital and treated with mechanical ventilation from March to August in 1997, two different ventilator strategies were employed randomly with flow control ventilator. In the high-FR group, the FR was fixed at 10 L/ min and the PL was adjusted according to the arterial blood gas analysis (ABGA) results. In the low-FR group, the FR was adjusted to 10 mL/kg of tidal volume. Sixty neonates were enrolled, 32 in high-FR and 28 in low-FR group. Ventilatory indices and clinical outcomes were statistically cornpared in the two groups. RESULTS: Perinatal factors were not different in the two groups. Initial ventilator settings, ABGA results and ventilatory indices were not different. The tidal volume, fraction of inspired oxygen, peak inspired pressure and oxygenation index were higher and dynamic compliance was lower in the high-FR group compared to the low-FR group after 3 to 72 hours of ventilator care. In clinical outcomes, incidences of pulmonary interstitial emphysema, pneumothorax and chronic lung disease were significantly lower in the low-FR group. CONCLUSION: Low-FR with constant FR strategy resulted in better clinical outcomes in the ventilator care of neonates. We conclude that constant FR strategy prevents damage of the better compliant lung units and decreases the incidence of acute and chronic complications of ventilator care.
