Tumor angiogenesis has been found to have prognostic significance in many tumor types for predicting an increased risk of metastasis. We assessed tumor vascularity in 28 cases of borderline malignancy and 71 cases of carcinoma of the ovary which had been resected and diagnosed, using the highly specific endothelial cell marker CD34. The numbers of microvessels were counted in 200 magnification in three highly vascularised areas. The numbers of microvessels in carcinomas were higher than that in the borderline malignancy of serous and mucinous tumors. The number of microvessels of mucinous carcinomas was significantly higher than that of serous carcinomas. There were neither significant differences in the number of microvessels according to histological tumor types (p=0.075) nor significant differences in the number of microvessels according to FIGO stages (p=0.072). But in serous carcinomas, the number of microvessels was higher in the FIGO III-IV stage than in the FIGO I-II stage (p=0.017). This study showed higher neovascularization in malignant tumor than borderline malignancy, and in the advanced stage (FIGO III-IV) than less advanced stage (FIGO I-II) of serous carcinomas.

Journal of the Korean Child Neurology Society 1998;6(1):133-137
The authors present a case of spontaneous discitis in a 1-year-old female who presented with fever and limping gait. The erythrocyte sediment rate was increased. The roentgenograms revealed normal appearnce, and radioactive bne scan showed increased uptake at the affected level. Discitis should be considered in any child with limping gait or leg pain, refusal to walk, or abdominal pain. Early recognition may avoid unnecessary diagnotic and treatment procedures.

The introduction of the strong clover-leafed nail combined with the principle of reaming out the medullary canal and the development of image intensifiers has been extended the indications of the in tramedullary nailing. In this report, an attempt was made to introduce the method and to verify the indications and advantage of retrograde intramedullary nailing of humeral shaft fractures, as compared with the conventionally accepted methods.

BACKGROUND: Silver has been used for disinfection and sterilization. We aimed to confirm the in-vitro antibacterial effects of nanocrystalline silver-coated gauze. METHODS: Fourteen clinical isolates each of Escherichia coli and Acinetobacter baumannii were used. Bacterial suspensions made in tryptic soy broth were exposed to Ordinary and silver-coated gauze. Bacteria were then harvested from the gauze immediately and after 24 h incubation, cultured on blood agar plates and eunmerated for viable counts. The number of colonies was converted into common logarithms for comparison. RESULTS: The number of colonies recovered from silver-coated gauze was significantly lower than those recovered from ordinary gauze when harvested immediately after exposure (E. coli, 3.06 vs 1.73; A. baumannii, 3.13 vs 1.98; P<0.001). After 24 h incubation of exposed gauze, silver-coated gauze produced less than 1 CFU/mL, whereas ordinary gauze produced a number of colonies significantly higher than it did immediately after exposure (E. coli, 4.13; A. baumannii, 4.46; P<0.001). Conclusion: Compared with ordinary gauze, silver-coated gauze was shown to have 99.99% antibacterial effect.

Necleolar organizer regions(NORs) ARE LOOPS OF DNA which transcribe to ribosomal RNA by RNA polymerase I. Since NOR-associated proteins are argyrophilic, silver staining method has been used for demonstration of AgNORs. The numbers and/or configurations of NORs may reflect the activities of cells in hyperplastic and neoplastic conditions. To evaluated the applicability of AgNORs in the diagnosis of hepatocellular carcinoma, the author had performed silver staining on the routinely processed, formalin-fixed, paraffin-embedded sections of 14 cases of normal liver(control), 23 cirrhotic liver, and 21 hepatocellular carcinoma. The results are summarized as follows: 1) The mean number of AgNORs per nucleus(mAgNOR) of normal liver, cirrhotic liver and hepatocellular carcinoma was 1.45+/-0.07, 2.53+/-0.38 and 5.52+/-1.63, respectively. The difference of mAgNOR between normal and cirrhotic liver, and between cirrhotic liver and hepatocellular carcinoma was statistically significant, respectively(p<0.01). 2) The percentage of nuclei showing five or more AgNORs per nucleus(pAgNOR) was 0.07% in normal liver, 7.59% in cirrhotic liver, and 60.49% in hepatocellular carcinoma. 3) AgNORs in hepatocellular carcinoma were large, pleomorphic and irregularly clumped, in addition to increase of mAgNOR and high pAgNOR. In conclusion, the increase of mAgNOR, high pAgNOR and large, irregular AgNORs are regarded as an additional helpful finding for the histopathological diagnosis of hepatocellular carcinoma.

Total 481 cases of gallstones from Korean patients operated at Keimyung University Dongsan Hospital during the last 6 years were classified by macroscopic view according to the classification of Sato, et al and reviewed with a special reference to age, sex, and kinds and sites of gallstones. Gallstrones were present predominatly in the age of 50-60 years, the average 52. Sex ratio (M:F) was nearly equal, being 1:1.05. Gallbladder was the most frequent site, comprising 53.2%, followed by common bile duct, 23.3% and intrahepatic location, 3.7%. Macroscopic classification revealed pigment gallstones in 53.0% (calcium bilirubinate, 41.8%; black, 11.2%); cholesterol gallstones in 36.2%, of which mixed stone being 33.1%. Cholesterol gallstones occurred predominantly in 50-60 years of age with a prediletion to females. On the contrary, elderly persons more than 60 years of age had calciu bilirubinate stones. No sex difference was found in the calcium bilirubinate stones. Eightly-six percent of cholesterol gallstones were present in the gallbladder only. Common bile duct stones were mostly composed of pigment gallstones in 80.4%.

The second case of this serial reports under the title of unusual cutaneous manifestations of connective tissue diseases is a woman with primary idiopathic dermatomyositis who developed cutaneous ulcerations on her arms and legs, which is thought to b a rare manifestation of adult dermatomyositis. These multiple ulcerations are about bean sized, polymorphous, and grouped on the poikilodermatous lesional skin. In this patient these ulcerative lesions became regressive and healed with disfiguring scars after the activity of the disease has controlled by prednisolone and methotrexate.

Majocchi's disease is one of chronic vascular disorders of the skin, histologically showing capillaritis with lymphoid cell infiltration. Although the hypothesis of delayed type hypersensitivity reaction against foreign antigen is proposed as the mechanism producing this condition, there are much yet to be defined. We tried to examine the lesional skin of five patients with Majocchi's disease by the direct immunofluorescence with anti-human immunoglobulins, C 3, and fibrin. As a result we found the deposition of immunoglobulins (M, and G) in papillary blood vessels in four patients, and C 3 and fibrin were found in all five patients. C3 was also found at the dermoepidermal junction in three patients. These findings suggest the posssibility that antibody mediated immunologic processes may alsobe involved in the pathogenesis of this disorder. With this observation Majocchis disease could be considered as a chronic immune vasculitis.

Peutz-Jeghers polyp with pseudoinvasion is characterized by the presence of mucosal islands within muscle layer often associated with mucinous cysts. It occurs when mucosal components completely penetrate the muscularis propria, and shows no cytologic signs of malignancy. In most instances, the lesion may be the result of forces exerted during intussusception in the involved small intestine. We describe a case of Peutz-Jeghers polyposis with pseudoinvasion in a 24-year-old female patient. This patient presented with intussusception and a segmental resection of the ileum was performed. Microscopically, it disclosed a hamartomatous polyp with pseudoinvasion. There were glandular islands and mucinous cysts embedded within the bundle of muscle, layer, extending, to the subserosa. There was o evidence of cellular dysplasia or desmoplasia.
