To evaluate correlation between the expression of neu and ras oncoprotein and epidermal growth factor receptor on breast carcinoma and other known prognostic factors, immunohisto-chemical studies were performed. Positive reaction for neu, which appeared as brown granular deposits along cell surface and cytoplasm of the tumor cells, was significantly correlated with the histological grade but not with other prognostic factors such as tumor size, lymph node me-tastasis, local recurrence, and estrogen and progesteron receptor status. Also granular deposits of ras were noted in the carcinoma cells in the cytoplasm, while the epithelaial cells of the normal lobule and duct showed negative reation. But expression of ras was not significantly associated ras with other prognostic factors. The reaction for EGFR was mostly negative on epithelial cells of both the normal lobule and duct, and was not significantly associated with other prognostic factors. The results suggested that expression of the neu oncoprotein is significantly associated with the histological grade of breast carcinoma, while the ras and the EGFR do not show significant prognostic value.

For the elucidation of a possible pathogenetic mechanism of fatty accumulation by the orotic acid in the liver, male Sprague-Dawley rats were fed on semisynthetic diet containing 1 per cent orotic for a week, and followed by the morphological examination on the rat livers. The experimental animals were sacrificed on the 1st, 2nd, 3rd, and the 7th days of orotic acid feeding and daily sacrifice was performed after conversion to normal diet feeding during the performed after conversion to normal diet feeding during the period of successive 7 days. The control group animals were fed on normal regular diet, or semisynthetic diet without orotic acid. The liver tissues were examined by the light ad electron microscopy, together with electron microscopic cytochemical study for glucose-6-phosphatase and thiamine pyrophosphatase. On the light microscopy, the lipid droplets began to appear in the 3rd day of orotic acid feeding and then occupy through the all hepatic lobules in the 7th day of orotic acid feeding. On the electron microscopy in the 3rd day of orotic acid administraion, the endoplasmic rdticulum were fragmented and vesiculated, and vesicles containing VLDL particles were demonstrated closely around the Golgi complex. In the 7th day, Golgi complex were increased in numbers. The limiting membrances of lipid vacuoles were regarded to originated from rough-surfaced endoplasmic reticulum of account of demonstration of glucose-6-phospatase in them. In the Golgi complex the activity of thyamine pyprophosphatase were markedly decreased in the 1st day of orotic acid feeding, and then the activity of this enzyme is failed to present afterthat. On the above findings it is assumed that orotic acid depresses the function of trans aspect of Golgi stack and the VLDL is interrupted and followed by the retrograde accumulation of VLDL. The cis aspect of Golgi stack and rough-surfaced endoplasmic reticulum were accumulated with VLDL particles, and eventually coalesced vesicles of VLDL with become lipid vacuole. The sequential alteration of endoplasmic reticulum and Golgi complex is supporting the concept of conformational change of membranes in cytocavitary net-work.

Primary tumors of the heart are rare, and one-third of them are malignant. The most common malignant intracardiac tumor is angiosarcoma, which usually involves right atrium. MR features in one patients with right atrial angiosarcoma is presented and the literature briefly reviewed. Angiosarcoma demonstrated slightly heterogeneous intermediate signal intensity on T1-weighted images, high signal intensity on T2-weighted images and higher signal intensity on Gd-DTPA enhanced images. MRI provided more information regarding the extent of the tumor than 2D echocardiography or CT.

OBJECTIVE: The purpose of this study was to analyse clinical manifestations and laboratory findings in childhood patients with polyarticularonset juvenile rheumatoid arthritis (JRA). METHODS: Eleven cases of polyarticular JRA who were diagnosed and treated in the Department of Pediatrics, Seoul National University Children's Hospital from June 1988 to May 1995 were investigated for clinical manifestations and laboratory findings. RESULTS: 1) There were 6 males and 5 females and their ages of onset were 4 years to 15.1 years(mean 10.9 years). 2) Systemic manifestations were not observed, but low-grade fever was noted in 5 patients. 3) The involvement of joints was symmetric in 9 patients and asymmetric in 2 patients. 4) The most commonly affected joints were knees and ankles, followed by proximal interphalangeal joints of hand, shoulder, elbow, temporomandibular joint, and other joints. 5) Roentgenographic changes of joints were detected in 6 patients and bone scan in 7 patients showed increased uptake in the involved joints. 6) The main laboratory findings observed were microcytic and hypochromic anemia (64%), thrombocytosis (82%), elevated eryhtrocyte sedimentation rate (100%), positive or increased C-reactive protein(100%), positive rheumatoid factor(RF) (18%), positive antinuclear antibody(ANA) (27%). RF was positive in 2 girls with later age of onset and the pattern of immunofluorescent ANA were all homogeneous. 7) Nonsteroid antiinflammatory drugs (NSAIDs) were used most frequently and steroid with or without sulfasalazine was tried in 4 patients unresponsive to NSAIDs. 8) At last follow-up, 6 cases(55%) were classified as functional class I, 4 cases(36%) as class II, and 1 case(9%) as class III. CONCLUSION: These data showed the clinical manifestations and laboratory findings of polyarticularonset juvenile rheumatoid arthritis in Korean children.

Serologic tests for syphilis including VDRL and TPHA tests were carried out in 5,413 VISA applicants for emigration, from January, 1981 to December, l984 The results are summarized as follows: 1. In 5,413 VISA applicants, the reactive rate of VDRL test was 2,0% totally. The reactive rate of VDRL test of male was 2. 6%, and that of female was 1. 6% 2. The reactive rate of 1983 was 1.4% and that was the lowest in annual incidence, but there was no statistically significant differences in comparing the annual incidences. 3. The reactive rate increased with age, and males above the 5 th decade revealed an especially high reactive rate. 4. The biologic false positive rate of VDRL teet was 16. 5%, in gl VDRL reactive persons, using TPHA as standard. 5. The quantitative test of VDRL showed low titer below 1: 4 in 88. 4%, and high titer above 1: 8 in 11. 6% of the applicants.

Morphologically, kyphosis is devided into two groups, pure kyphosis and kyphoscoliosis, according to whether or not scoiiosis is combined. Or kyphosis can be devided into round kyphosis or angular kyphosis. The examples of round kyphosis are Scheuermanns kyphosis or ankylosing spondylitis. Acute angular kyphosis are of congenital kyphosis or old healed tuberculosis. The purpose of surgical correction of fixed kyphosis is to correct deformity as well as to prevent or to recover from paraplegia. The operation also improve respiratory and digestive function by diminishing compression of abdomen. However, the correction of this deformity is more dangerous in eliciting paraplegia than any other spinal deformity. In considering surgical correction of kyphosis we have to decide which approach is the best for that particular patient at that particular time. Usually majority of patient need combined anterior and posterior approach. The extent of fusion depends upon the flexibility of the kyphosis. Anterior fusion should encompass at least the rigid and inflexible portion of the kyphosis as determined by the hyperextension x-ray of the spine. Posterior fusion should encompass the full extent of the kyphosis. The purpose of this study is to report our results for surgical correction and to find the operative procedure which shows the best result. We hereby report surgically corrected 14 cases of fixed kyphosis who were hospitalized here from April 1988 to February 1995.
