The clinical and pathological features of a case Malignant mixed mullerian tumor of the ovary in 45 year-old female patient with a brief review of the literature are presented. She had both ovarian tumors. The masses are multilocular cystic tumor with interspersed solid component. The cystic component is filled with serous fluid. Microscopically the tumor is composed of epithelial element & intimately related mesenchymal element. The epithelial element shows the findings of adenocarcinoma of solid, glandular and papillary growth. The mesenchymal element is composed of malignant-looking stroma with cartilage formation.

Fibrous histiocytoma composed of fibroblasts and histiocytes is quite variable in histologic pattern. The biologic behavior is unpredictable by histologic ground. This tumor is well-known in subcutaneous tissue and deep soft tissue, but quite rare in central nervous system. We experienced a case of the fibrous histiocytoma involving the dura mater of spinal cord in a 26 year old female patient. In gross findings, the mass was a well demarcated, ovoid mass attached to the dura matter, and measured 2.5x1.5 cm in diameter. The cut surface was rubbery, solid, gray-white or yellow. Microscopically, the lesion consisted of polyhedral cells with round or oval nuclei and faintly eosinophilic or vaculoated cytoplasm, and multinucleated giant cells. Some giant cells were Touton-type. Composing cells were bland-looking. Mitotic figures were average 3 per 10 high power fields.

Primary germ cell tumor of the testis is rare, which occupies 1 to 2% of all reported malignant male neoplasms. Combined primary germ cell tumor of the testis composed of embryonal carcinoma and seminoma is more rare tumor. The authors experienced a case of 50-year old male who presented with painless enlargement of right testicle. He has had radical orchiectomy and diagnosed by pathologically as combined germ cell tumor of testis. The testicle is measuring 180 gm in weight and 9×6×5 cm in dimension, and almostly replaced by tumor mass. Grossly the tumor is rubbery solid smooth tumor mass, with variegated cut surface with geographically outlined diffuse necrotic area. Histologically the tumor is composed of two components of tumor, which are solid growth pattern of large round to polyhedral cells with clear or granular cytoplasm and distinct cell border, and anastomosing glandular and papillary arrangement of anaplastic epithelial cells. The former corresponds to seminoma, and the latter to embryonal carcinoma. Each tumor lobule is separated by abundant fibrous stroma.

Antioxidative function of uncooked powdered food (Sangsik) was evaluated in rats consuming nutritionally unbalanced diet including 1% cholesterol, high proportion of animal lipids (lard : soybean oil : 8 . 2) , sub-optimal levels of vitamin and mineral mixture along with 0.5% ethanol in drinking water. The uncooked powdered food tested in the present study was a mixture composed of 42 kinds of plant foods (cereals, legumes, seaweeds, vegetables, and fruits) supplemented with vitamins and minerals, and dietary fiber. Control rats were fed the semi-purified diet based on the AIN-93G composition, and nutritionally unbalanced rats were divided into 3 groups, and fed one of the following diets with 0.5% ethanol in drinking water for 5 weeks : unbalanced control diet (UC) ,20% Sangsik powder supplemented diet (S20), and 40% Sangsik powder supplemented diet (S40) . Food efficiency ratio was significantly higher in rats fed S40 compared to the value for rats fed UC (p<0.05). Hepatic level of thiobarbituric acid reactive substances (TBARS) was significantly lower in rats fed UC compared to that for control rats (p<0.05), and was not influenced by dietary supplementation of the Sangsik powder. Hepatic superoxide dismutase (SOD) activity was significantly higher in rats fed UC compared to that for control rats (p<0.05), and significantly reduced in rats fed S20 or S40 compared to the value for unbalanced control rats. Feeding unbalanced control diet significantly reduced the ratio of hepatic GSH-Px + catalase/SOD activities compared to the value for control rats, and this decrease in the ratio of antioxidant enzyme activities was reversed by adding the Sangsik powder to the diet at 20% (p<0.05) . Based on the results of antioxidant enzyme activities, feeding uncooked powdered diet appears to provide a favorable environment for body's antioxidative defense mechanism. Serum levels of Fe and Cu were significantly lower in rats fed the Sangsik powder supplemented diets compared to the value for unbalanced control rats (p<0.05), and levels of Se, Mn, and Zn were also tended to be decreased by dietary supplementation of the Sangsik powder. These results postulate the possibility that ingredients used in the uncooked powdered food may decrease the bioavailability of trace elements in rats.

A total of 23 human fetal hearts from 18 to 40 weeks of gestation were provided for histologic and morphometric studies. The fetuses were the products of spontaneous or artificial abortions and were found to have no congential anomalies or associated lesions at autopsy. Maxima thickness of the left anterior, left lateral, left posterior, right anterior, right lateral, right posterior ventricular wall, and of the interventricular septal wall were measured and the left / right wall thickness ratio was calculated. The cross-sectional area of each ventricle parallel to the base of the heart at about 3-5mm below from the origin of the aorta was measured under drawing attachment-equipped light microscope with the application of point counting or cut-and-weigh method. Data were analyzed by the Anderson-ell ABSTAT dBASE ll statistical package program. The ventricular wall consisted of endocardium, myocardium and epicardium. The myocardium showed epithelial character by stratification of barrel-shaped myocardial cells, but the epithelial character progressively changed to as in adult myocardial tissue from the myocardial area close to the epicardium with increasing fetal age. However, any significant histologic difference between the left and the right ventricular wall at the same fetal age was not found. The growth pattern of both ventricular wall, the interventricular septal wall, and of the cross sectional area were linear (p<0.01). However, there was no significant difference in the wall thickness between the left and right ventricle at the same fetal age, and the left / right thickness ratio was nearly constant with increasing fetal age. The cross sectional area was greater in the right than in the left ventricle in the fetuses after 18 weeks of gestation (p<0.01), and there was no significant difference in the morphometric values between point counting and cut-and-weigh method (p>0.1).

Ancient schwannoma is a variant of schwannoma and is characterized slowly growing tumor with degenerative change. And it is reported that schwannoma is relatively rare in extensor area. As a rare cause of solitary ancient schwannoma in extensor area of upper arm, we report it.

We report a case of type IV hyperlipoproteinemia associated with xanthoma tuberosum and diabets mellitus in a 48 year old female patient. She had several yellowish-brown papules on the knees and palms. The blood glucose level was elevated and serum lipid and lipoprotein analysis revealed patterns of type IV hyperlipoproteinemia. Histopathologic findings of yellowish-brown papules on the knee showed the aggregation of foam cells in the dermis. She has been treated with diet control and hypolipidemic drug(lovastatin and procetofen) and is under our continuing supervision.
