PURPOSE: Misdiagnosed breast cancer on screening mammography was retrospectively reviewed in an attempt to analyze the cause for the undiscovery and to determine findings that might have been suggested on the mammographic examination. MATERIALS AND METHODS: Of the 173 breast cancers that were pathologically proven, 17 breast cancers misdiagnosed on mammogram was retrospectively analyzed for the causes of the misinterpretation and predominant secondary findings. RESULTS: Three of the 17 were negative on mammography except for dense breast. Two patients had localized asymmetricity without visible mass. Ten patients had benign-looking mass which was well-defined (n=5), partially defined(n=2), multiple (n=l), or included benign-looking calcifications(n=2). Remaining two cases were retrospectively diagnosed as misinterpreted breast cancers. Various secondary findings such as were useful in the diagnosis of breast cancer. CONCLUSION: Meticulous observation could improve the diagnostic yield of breast cancer in mammography.

OBJECTIVE: To evaluate whether the rate of early mouse embryonal development could be enhanced by cumulus cell coculture in vitro. METHODS: Ham's F-10 culture media supplemented with 0.4% bovine serum albumin were used. Two-cell F1 mouse embryos were cultured in media with or without cumulus cells of female ICR mouse embryo for 96 hours, and the rates of embryonal development were observed and compared. RESULTS: The percentage of hatched blastocyst in the coculture group was significantly higher than that in the control group by 87.3% vs 64.8% respectively (p< 0.05). CONCLUSION: This study provides confirmative information that cumulus cell coculture will be useful in enhancing early mouse embryonal development.

Journal of the Korean Radiological Society 1997;37(6):1039-1042
PURPOSE: To analyse Doppler findings in patients with chronic venous insufficiency, and evaluate the usefulness of color Doppler ultrasonography. MATERIALS AND METHODS: Thirty-seven limbs in 29 patients were evaluated with color Doppler ultrasound for suspected chronic venous insufficiency. To determine luminal patency and valvular competence, the venous system was examined; more than 1 sec of reflux flow during Valsalva maneuver and after release of distal compression in the popliteal vein indicated incompetence. RESULTS: Venous insufficiency was seen in 30 cases (81%), and was Superficial in 14 (38%), deep in eight (21.5%), and combined in eight (21.5%). In seven limbs (19%), veins were normal. Six cases of insufficiency, four of which were deep, were combined with deep venous thrombosis. CONCLUSION: In cases of chronic venous insufficiency, color Doppler ultrasound is useful for defining the exact site of venous incompetence and evaluating venous luminal patency.

BACKGROUND: As people have been interested in healt,h and as the microcomputers with multimedia steeing have been supplied more and more, there is increasing need of multimedia information about health. The CD-ROM, which is a representative multimedia tool, is capable of interacting between information-provider and users, offering audiovisual interface, and saving great deal of knowledge. METHODS: We developed the health-information system to provide ordinary people with hea1th information using multimedia tools. It, has 7 parts ; self-diagnosis, exploring human body, drug information, hospital information, first-aid treatment, Q and A, and medical common sense. We got image data such as figures, photos, X-rays, electrocardiograms and pathologic specimens with scanner and film scanner, also moving image(video) with video-capturing program. RESULTS & CONCLUSIONS: We hope the multimedia health-information system to become a useful methodology of patient education and to be used as an information source in medical information network in the near future.

BACKGROUND: Common and effective treatments for calcific tendinitis involve needling procedures. However, it has been widespread practice to refer patients with calcific tendinitis, which is a predominantly orthopedic condition, to radiology department. The purpose of this study was to compare clinical and radiological outcomes after ultrasound-guided needling for calcific tendinitis between the orthopedics and radiology department. METHODS: Seventy-seven shoulders (Group 1) and 38 shoulders (Group 2) treated in the radiology and orthopedic department, respectively. A fellowship-trained orthopedic surgeon and a musculoskeletal radiologist each performed the procedure of ultrasound-guided needle decompression with subacromial steroid injection. Clinical outcomes was evaluated using the visual analogue scale for pain (pVAS) and the American Shoulder and Elbow Surgeons (ASES) shoulder score before treatment and at each follow-up. The pre- and post-needling size and shape of the calcific deposits were compared between the two groups. RESULTS: We analyzed a total of 56 shoulders for Group 1 and 32 shoulders for Group 2. The mean age and sex ratio of the patients no significantly different. We found that the mean decrease in the diameter of calcification between pre- and post-needling was 9.0 mm for Group 1 and 13.1 mm for Group 2; the difference was significantly larger in Group 2 than in Group 1. Both groups showed improved pVAS and ASES scores after needling but the extent of these improvements did not differ with the type of operator. CONCLUSIONS: Needling decompression performed by orthopedic surgeons could a viable option for the treatment of calcific tendinitis.

Nine cases of primary localized cutaneous amyloidosis were studied by immunoperoxidase technique (ABC method) employing anti-keratin antibodies. All specimens were examined using consecutive paraffin sections to confirm the correspondence between amyloid existing area and reactive sites. Anti-keratin antibody 34pE which recognize 68, 58, 56.5, 56kd keratin peptides reacted with amyloid deposits in both lichen amyloidosus and macular amyloidosis. However, anti-keratin antibodies 34pB4 and 35pH did not react with amyloids. In general, Dylon staining positive material, keratin reacted with 34pE and amyloid P showed similar distribution in serial sections, but did not show the same one. Several keratin bodies reacted with 34pE, which were not stained with Dylon staining or antiamyloid P were found in the dermis of one specimen. These results suggest that immunohistochemical staining with antikeratin antibody 34pE using formalin-fixed, paraffin-embedded sections appeared to be a useful method in studying the histogenesis of primary localized cutaneous arnyloidosis.

9.Sonographic Measurement of the Normal Gallbladder Size in the Korean Children.
Journal of the Korean Radiological Society 1996;34(1):121-125
PURPOSE: While normal ultrasound measurement of the gallbladder (GB) is well established in adults, little attention has been focused on the normal measurement of the pediatric gallbladder. Normal parameters of the pediatric gallbladder may be significant to establish disease criteria, because some gallbladder diseases are only accompanied by changes in gallbladder size. We therefore wish to document the normal ultrasonic parameters of the pediatric gallbladder. MATERIAL AND METHOD: Five hundred and ten children with normal clinical findings andlaboratory data were included in this study. Ultrasonography was performed as a part of a health screening examination from the Dec. 1994 to Feb. 1995. Sonographic parameters included gallbladder size, volume, and clinical parameters such as age, height, weight, and body surface area were noted stastical significance between the sonographic and clinical parameters was analyzed through correlation and regression analysis. RESULTS: The patient age was ranged from 0 to 16 years, and the male : female ratio was 1.5 : 1. The longitudinal length of GB showed significant positive correlation with patient age(0.504), height(r=0.527), body weight(r=0.492), and bodsurface(r=0.522)(p <0.0001). The result of correlation analysis and regression analysis to the volume of gallbladder was also significant(r : 0.403-0.515, p <0.0001). The correlation analysis to the transverse length of gallbladder shows relatively low correlation coefficiency(r=0.290-0.398), however, the result of regresion analysis shows significance(p <0.0001). The range of mean value of gallbladder size according to age was 3.32(+/-0.73)-6.81(+/-1.05)cm in longitudinal length, 1.10(+/-0.37)-2.01(+/- 0.57)cm in transverse length, and2.46(+/-1.66)-15.35(+/-8.18)cm3 in volume. CONCLUSION: The mean values of pediatric gallbladder may be an useful index for the clinical application to vanior gallbladder disease.

This study was undertaken to document the effect of transforming growth factor-beta2 (TGF-beta2(TGF-beta2) and basic fibroblast growth factor (bFGF) on the proliferation of pig retinal pigment epithelial cells (RPE). Whereas bFGF increased the proliferation, TGF-beta2 showed the inhibitory effect on the proliferation The inhibitory effect of TGF-beta2 disappeared in RPE subcultured with 10ng/ml of bFGF. Both TGF-beta2- and bFGF-specific antisense oligonucleotides blocked the autocrine effect of the growth factors. PLC-71 -specific antisense oligonucleotide inhibited the effect of TGF-beta2 and bFGF. Genistein inhibited the effect of TGF-beta2 and bFGF in dose-dependent man, ner. The data suggest the involvement. of in PLC-/1 and tyrosine kinase in signalling.
