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.

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.

For the chronic renal failure(CRF) patients arteriovenous fistula(AVF) is performed on the upper extremity. The primary site is usually the wrist including snuffbox where diameter of the vessels is small, usually one to three millimeters. The trainee of general surgery has been lack of experience of small vessel surgery. Here on the basis of experimental microsurgery, novel animal practice model of AVF was developed for the clinical application. Among several types of vascular anastomosis of AVF, side-to-side anastomosis with distal vein ligation were favored in this study. In brief, rats were anesthetized with intraperitoneal urethane injection and midline abdominal incision was made. Aorta and IVC below the left renal vein was exposed and seperated and mobilized carefully. Side-to-side and end-to-end anastomosis can be performed microsurgically. Loupe(x3.5-5) and experimental microscope may help to carry out vascular anastomosis confidently. The key-point of the procedure is that both corners of stomas were sutured for staying and from the one-end continuous sutures were done with total open-loop method.

This study was undertaken to investigate the efficacy of 5% PABA cream using mouse ear swelling reaction(ESR). Mice were exposed to 100mJ/cm of UVB, five times a week for four weeks, on the both ventral aspect of the ear, with application of 5% PABA cream on the right ear. The results were as follows : 1. The intensity of ear swelling reaction of 5% PABA protected group was reduced greater than unproteeted group after the first 3 days of UUR. 2. The intensity of ear swelling reached at peak after 1 week of the ultraviolet radiation. Thereafter it has decreased gradually the following 4 weeks. The difference of ear swelling between the two groups was the greatest after 1 week, and the sunscreening efficacy of 5% PABA cream has remained persisted for 4 weeks. 3. The number of mice which have shown severe inflarnmatory response after ultravioiet radiation was more in unprotected group than that in 5% PABA protected group. 4. Determination of mouse ESR is considered a good method for the evaluation of longterm efficacy of sunscreen preparation.
