80 cases of Cysticercosis were studied and analysed, which were diagnoses by biopsy at Seoul National University in the past three years from January-1978 to March-1980. The results were summerized as follows. 1. The relative incidence ratio of cysticercosis among 18,941 surgical specimens was 0.42%. 2. The age group between 11 and 50 years old occupied 87.5%. 3. Of the 80 cases, there were 38 males and 42 female patients, without significant sex predominence. 4. The common sites of cysticercosis were upper extremities (35.0%) and anterior surface of the trunk (37.5%) 5. Epidemiologically, there was marked predominence of rural area over urban area. 6. There were 8 cases (10%) of definite cerebral cysticercosis and 4 cases (5%) of suspicious cerebral cysticercosis. 7. In the cases of nodular masses of extremities, the parasitic infection, especiaily cysticercosis celluiosae, must be included in differential diagnosis distinguished from other soft tissue tumors.

A 28-year-old male patient is described who developed multiple erythematous nodules and papules on the face, upper chest, back, upper and lower extrimities, leading to extensive ia.filtration of the skin and lymph nodes. Histology from the involved lymph node and skin nodule revealed widely scattered patchy infiltration of abnormal. hyperchromatic polymorphous histiocytes in the dermis. The patient died at about 8 months after onset of the disease, in spite of antineoplastic treatment.

BACKGROUND: The purpose of this study was to examine the perceptions and use of premium snacks (PS) in school aged children. In addition, the influence of their mothers attitude toward the PS use on the children's PS eating behavior was examined. METHODS: 337 boys and 292 girls and their mothers (n=535) were participated in this study. Participants were recruited from two elementary schools located in Kyung-ki area. Information on general characteristics, the frequencies of general snack eating and associated factors, and the frequencies of PS eating and associated factors were obtained by a self-administered questionnaire. RESULTS: The mean frequency of PS eating were 1.12 times/wk in boys and 0.98 times/wk in girls. The PS eating frequency was positively associated with the frequency of eating general snacks in boys and the money spent on purchasing general snacks in girls. The main reasons for eating PS were 'health' followed by 'taste'. The frequencies of general snack eating and those of PS use in mothers were highly associated with the frequencies of eating PS in children. Further, the perceptions on PS in mothers were significantly correlated with the frequencies of PS eating both in boys and in girls, although correlation coefficients were somewhat weak. CONCLUSIONS: Our study showed that mother's snack eating behavior and perceptions can affect their children's PS uses. Our findings suggest that the education toward the mother's eating behavior and nutrition knowledge are important in improving child's eating behavior including reasonable and healthy snack choices.

It is well known that the incidence of revision arthroplasty for the loosened total hip has been progressively increasing recently. And the problem is that the loosening rate of revision arthroplasty for the failed total hip replacement is much higher as compared with that of primary total hip replacement. In revision arthroplasty, Amstutz, in 1982, reported 9% incidence of mechanical failure and 43% incidence of femoral and 61% incidence of acetabular progressive radiolucencies with follow-up for an average of 2.1 years, and Pellicci, in 1985, reported 29% incidence of failure for total hip replacement that have been revised once in the radiolucent zone with the follow-up for an average 8.1 years, and Kavanagh, in 1985, reported that probable loosening occurred in 25% of revised acetabular components with follow-up for an average of 4.5 years. Cementless total hip replacement is successful in more than 90 of the primary cases for the last 5 years in our department. Therefore, not only in primary total hip replacement but also in the revision, it seems to be reasonable to perform the cementless total hip replacement as an alternative, particularlly, in young age group. During the period from April 1982 to December 1984, we have revised 12 loosened total hip replacement with cementless type. Average follow up was 1 year and 7 months. The age range of the patients was 23 to 64. The results are very promising without any evidence of loosening in all cases.

PURPOSE: To evaluate morphologic characteristics of the clustered microcalcifications in benign lesions and to compare with that of malignant lesions. MATERIALS AND METHODS: We retrospectively reviewed 33 patients with clustered microcalcifications( five calcifications in number per square centimeter)on mammography. We analyzed mammographic findings with regard to shape, size, number/cm2, irregularity of size and shape, presence of central lucency, and accompanied mass density. RESULTS: Of 12 benign lesions, the most frequent shape was dot or round form (4/12, 33.3%) followed by ring form (3/12, 25%). The size was smaller than 0.5mm in 5 patients (41.7%), 0.5-1 mm in one and more than 1 mm in 6 patients(50%). The number of calcifications per square centimeter were five to ten in 41.7%, more than ten in 58.3%. Of all 21 malignant lesions, the most frequent shape was branching form (8/21, 38.1%). The sizes of calcification were less than 0.5ram in 76.1%(16/21). Central lucency within the calcification was seen only in benign lesions (3/14, 21%). Irregularity ih size and shape of calcifictions was noted in both benign and malignant lesions. Accompanied parenchymal mass density was more commonly associated with malignant lesions(80. 9%) than benign lesions(58.3%). CONCLUSION: Our results suggest that benign clutered microcalcifications on mammography could be differentiated from malignant calcifications with the criteria of larger size, central lucency and infrequent accompanied mass.

The present study was performed to investigate the role catecholamine in the genesis of reperfusion injury of ischemic heart. The possible involvement of catecholamine in the xanthine oxidase-linked production of oxygen free radicals was studied. langendorff preparations of rat hearts were made ischemic for 60 min followed by reperfusion. Upon reperfusion norepinephrine(NE) was significantly released into the coronary effluent regardless of oxygenation of the perfusion solution. Both the increased releases of creatine phosphokinase(CPK) and malondialdehyde(MDA) and the production of superoxide anion in the ischemic-reperfused hearts were significantly reduced by the treatment with either reserpine, a catecholamine depletor, or propranolol, a beta-adrenergic receptor blocker. In the reserpinized hearts, infusion of exogenous NE reversed the releases of CPK and MDA and the superoxide anion production to the original higher levels. The releases of CPK and MDA as well as the production of superoxide anion induced by NE in the reserpinized hearts were significantly depressed either by allopurinol, a specific competitive inhibior of xanthine oxidase(XOD), or by the calcium removal from the perfusion solution. Compared with the XOD activity of control ischemic hearts, that of the hearts treated with reserpine or propranolol showed lower activity in the oxygen radical producing 0-form and higher activity in D/0-form. In the reserpinized ischemic hearts, infusion of exogenous NE increased 0-form, but decreased D/0-form of XOD. The changes in XOD activities induced by exogenous NE was prevented by phenylmethylsulfonyl fluoride(a serine protease inhibitor) and pimoxide(a calmodulin inhibitor) as well as by calcium removal from the perfusion solution. It is suggested from the results that in the inchemic-reperfused heart of rat catecholamine participates in D/0 to 0-form conversion of XOD by promoting the calcium-calmodulin-dependent proteolysis and plays a contributing role in the production of oxygen free radical.
