A 55-year-old woman suffered from upper abdominal pain for two months and remained refractile against the anti-ulcer regimen. The palliative gastrectomy specimen revealed multiple shallow ulcerations on the thickened mucosal folds mainly in the antrum and body along the greater curvature where multiple, whitish nodules were found in the submucosa. Microscopically, individual submucosal nodules clearly corresponded to the necrotizing granulomatous vasculitis which were featured with diffuse fibrinoid necrosis of arterial walls accompanying granuloma formation and heavy infiltration of neutrophils, eosinophils, histiocytes and giant cells. Similar vasculitic lesions involved venules and arterioles. There were scattered vasculitic changes in the liver biopsy specimens and omentum. There were no clinical presentations or serological support of systemic involvement including systemic lupus erythematosus, Henoch-Schoenlein purpura, cryoglobulinemia or Churg-Strauss granulomatous vasculitis. We conclude that this is a hitherto undescribed primary necrotizing granulomatous vasculitis predominantly involving the stomach.

Lipid cell tumors of the ovary are among the rarest of the functional ovarian neoplasms. Recently, authors experienced a case of lipid cell tumor of the left ovary in a 19 year old female, who presented with amenorrhea and hirsutism for 4 years. Grossly, the ovary was well encapsulated, and measured 6.5x6x4.5 cm. Cut surface show homogenous yellowish bulging neoplastic tissue and peritheral displaced normal ovarian tissue. Microscopically, neoplastic cells were composed of rounded and polyhedral cells, arranged in nests seperated by rich vascular networks. On the basis of the author's findings and the evidence available in the literature, we determined this case as ovarian lipid cell tumor.

A 55 year old male complain right shoulder pain and right upper quadrant pain about three months. He was a heavy alcoholism. Highly selective angiography, CT scan and operation findings suggest primary malignant neoplasm of the liver. Right hepatic lobectomy and partial diaphragmectomy was done under impression of heaptocellular carcinoma. The specimen measured 15x11x9 cm and disclose relatively hard and nodular mass devoid of cirrhotic changes. Cut surface show unilobar large mass measuring 11x8x6 cm and bearing brightly yellow discoloration and multifocal hemorrhagic necrosis. Histological characteristics were diffuse proliferation of large neoplastic cells with ample cytoplasm, containing granular materials, erythrophagocytosis, neutrophagocytosis and hemosiderin pigments. Atypical and bizarre mitosis and multinucleated giant cells bearing abundant erythro and neutrophagocytosis were frequently seen. The large or vesicular nuclei were irregular, with occasional deep indentations and revealed sharply defined nuclear membrane, coarse chromatin and conspicious nucleoli. Ultrastructurally the cytoplasm of neoplasltic cells had lysosomal granule, phagolysosome, phagocytized material and residual bodies. Immunohistochemical stains for alpha 1-antitrypsin, alpha 1-antichymotrypsin, vimentin and lysozyme showed positive reactions, but, alpha fetoprotein, cytokeratin, S-100 protein, factor VIII, complement 3 receptor and carcinoembryonic antigen were negative. Alpha-naphtyl acetate esterase activity in paraffin embedded tissue ribbon showed negative reaction. These findings show compatible with primary malignant lymphoma, true histiocytic type, (histiocytic sarcoma, Kupffer cell carcinoma) of the liver.

PURPOSE: The purpose of this study is to evaluate the relationship between developmental lumbar spinalstenosis and its BMD value by using the single energy quantitative CT(SEQCT). MATERIALS & METHODS: Eighty normal volunteers(20-60years) were selected as a control group and 28 patients with developmental lumbar spinal stenosis were selected as a disease group. The two groups were divided into a younger (20-39years) and an older subgroup(40-60 years), and were further divided into male and female subgroups. All the cases showed no evidence of metabolic disease, fracture, herniated nucleus pulposus, degererative spondylosis, infectious disease, tumors orhad no history of absolute immobilization of more than two weeks. All underwent lumbar spine CT and SEQCT. We measured bone mineral density(BMD) at the cancellous bone of L1, 2, 3 and obtained the mean and its one standard deviation, and compared the data between each subgroup of the control and the disease group using ANOVA. RESULTS: There was a significant low BMD value in the younger male patient subgroup compared with the control subgroup(P<0.05). CONCLUSION: Developmental lumbar spinal stenosis in a young male may be a factor of decreasing BMD of the body of the spine.

In attempt to investigate histone fractions and non-histones of parasites, nuclei were isolated from Fasciola hepatica by the procedure of Pogo et al. (1966). Histone fractions H1, H2a, H2b, H3 and H4 were prepared from isolated nuclei by the procedure of Johns (1964 and l967). The five histone fractions found in most tissues were also present in the Fasciola hepatica histones. These histone fractions were characterized by amino acid analysis and by polyacrylamide disc gel electrophoresis. Non-histone proteins were extracted from isolated Fasciola hepatica nuclei and separated by SDS-polyacrylamide gel electrophoresis. The results of the experiment were summarized as follows: The yield of whole histone recovered was 2.47 mg per 1 g of Fasciola hepatica. The yield of DNA was 1.02 mg per gm of tissues. Consequently the DNA to histone ratio was 1:2.44. The relative amounts of five fractions, i.e., Hl, H2a, H2b, H3 and H4 were 19.96 percent, 26.48 percent, 29.60 percent, 12.56 percent and 14.37 percent, respectively. Amino acid analysis of the individual histone fractions showed that the over-all compositions were similar but not identical to those of corresponding fraction from calf thymus. It was found that histone H2b fraction of Fasciola hepatica contained detectable amounts of epsilon-N-monomethyllysine. No evidence for the presence of methylated lysine or other side-chain derivatives was reported on this histone fraction. In SDS-polyacrylamide disc gel, it showed that 17 protein bands of nuclear acidic protein can be identified visually.

The present study was undertaken to observe the quality and quantity of lipid constituents by the developing Ascaris suum eggs. The collected eggs from the uterus of A. suum were classified into 3 groups, i.e., single cell stage, morula stage and embryonated eggs, and were subjected to analyse their lipid fractions. To obtain the morula stage eggs, 10 to 11 incubation days at 30 degree C were needed and for the embryonated eggs, 30 to 31 days were lasted. At the time of experiment, their indices of development by Hoffman were 285(morula stage) and 42 (embryonated stage) respectively. Lipid extraction was done by the methods of Folch et a1. (1957) and Kenny (1952), and then the extracted lipid fractions from the above 3 groups of eggs were separated by thin layer chromatography. Those fractions were also subjected to perform the quantitative analyses of fatty acids, glycerides, cholesterol and phospholipids. The results obtained were summarized as follows. Total amount of fatty acid was decreased from 12.9 mg per gram of eggs (single cell stage) to 6.6 mg/gm (embryonated eggs), whereas the proportion of free fatty acid to total fatty acid was constantly increased from 77.5 percent to 89.4 percent during the period of egg development. Total amount of glycerides was also increased from 33.0 mg/gm of single cell stage to 55.9 mg/gm of the embryonated eggs. The most abundant glyceride among 3 glycerides discovered from A. suum eggs was triglyceride, and the least was monoglyceride. The amount of free cholesterol was much larger than that of ester form in general, and it reached maximum in the eggs of morula stage (4.6 mg/gm). The increase of total cholesterol was monitored during the development of A. suum eggs from 3.3 mg/gm to 5.4 mg/gm. The following 8 phospholipids were detected in the embryonated eggs, i.e., lysophosphatidyl choline, phosphatidyl inositol, sphingomyelin, phosphatidyl choline, phosphatidyl glycerol, phosphatidyl serine, phosphatidyl ethanolamine and unknown phospholipid. But in the single cell stage eggs, 4 kinds out of the above 8 phopholipids were not observed, and in the morula stage eggs, 2 kinds were absent among the 8 phospholipids.

STUDY DESIGN: The authors designed the retrospective study with the Load-Sharing Classification in 47cases of the bursting thoracic-lumbar fractures, which were operated using the pedicle screws. OBJECTIVE: To judge the effectiveness of posterior short segment instrumented fusion in thoracic-lumbar fractures according to the Load-Sharing classification. MATERIAL AND METHOD: From 1995 through 1998, 47 patients who had been operated with short segment transpedicular instrumentation including fractured vertebra were selected and they were divided two groups, one below 6 point of Load-Sharing score, the other above 7 point. In follow up of average 39 months, the guide of reduction loss, which include the change of anterior vertebral body height and sagittal index were analysed statistically with the Student T-test at the postoperative time and the last follow-up time. RESULTS: In group below 6 point, the average of anterior vertebral body height was 56.2% before the operation and reduced 77.6% after the operation and measured 76.4% at final follow-up. The reduction loss was 1.2%. The sagittal index of preoperative 19.4degree became 10.6degree after the operation and measured 11.8degree at the last follow-up. The loss of correction angle was 1.2degree . In the other group above 7 point, anterior vertebral body height was average 51.7% before the operation and reduced 75% after the operation and measured 71.2% in last follow up, so reduction loss was 3.8%. Sagittal index was average 21.6degree before the operation and corrected 12.6 after the operation and measured 14.6degree in last follow up. All of 19 patients with neurologic deficits improved by over the one Frankel grade except grade A. CONCLUSION: Although the additional study is needed, there were no significant difference of statistical analysis about indexes between two groups.
