Authors performed film mammography in 2167 patients with breast complaints who had visited to Yong DongSeverance hospital, Yonsei University from October 1, 1983 to September 30, 1985. Authors analysed 62 cases offilm mammographic findings and 35 cases of ultra mammographic findings among confirmed 62 fibroadenomas and alsoauthors analysed histopathologic cell type and ultra mammographic findings of confirmed fibroadenomas. The resultsfollowed: 1. The most prevalent age group was 3rd and 4th decade(74%). 2. The common dense breast pattern by Wolfeclassification were P2 and DY patterns(80%) in film mammograhy. 3. The most common size of fibroadenomas was1.1-3.0cm (71%) in long diameter. 4. Film mammographic findings of fibroadenoma generally showed single mass in 54lesions(87%), well defined margin of mass in 45 lesions (58%) and halo sign in 62 lesions(80%). Well definedmargin of mass is prominant in ductal cell dominant fibroadenoma(71%) , however lobulation of margin is commonlyseen instromal component dominant fibroadenoma(15%) and spiculated margins of mass can be seen in mixedfibroadenoma(6%) and stromal component dominant fibroadenoma(3%). Halo sing of fibroadenoma was commonly seen inductal cell dominant fibroadenoma(86%) and stomal component dominant fibroadenoma(85%). 5. Ultra mammographicfindings of fibroadenoma showed oval shaped mass in 26 lesions(15%) with smooth margin of mass in 43 lesions(84%)and showed mostly intermediate internal echo in 48 lesions(94%). Relationship between histopathologic cell typeand ultra mammographic findings were. Round shaped mass(67%), lateral shadowing (74%) was common in mixed type offibroadenoma, lobulated margin of mass(45%), intermediate(94%) with unifrorm(78%) internal echo was common instromal dominant type of fibroadenoma and smooth contour (100%), uniform internal echo fo mass(83%) was common inductal cell dominant type of fibroadenoma. Most ultra mammographic L/T Iratio of fibroadenoma was 0.5-1.0 in 37lesions(73%) 6. The diagnostic accuracy of film mammogahy in fibroadenoma was 92%, however combined imagingmodalities raised the diagnostic accuracy into 95%.

PURPOSE: It is known that cyclooxygenase (COX)-2 expression is increased in Barrett's esophagus and esophageal adenocarcinomas. We studied COX-2 expression and the effect sulindac has on the genesis of Barrett's esophagus and adenocarcinoma in rats undergoing esophagogastroduodenal anastomosis (EGDA). MATERIALS AND METHODS: Fifty-one rats were divided into a control group (n=27), a 500ppm sulindac-treated group (n=15) and 1000 ppm sulindac-treated group (n=9). Randomly selected rats were killed by diethyl ether inhalation at 20 and 40 weeks after surgery. RESULTS: At 40 weeks, rats treated with 1000 ppm sulindac showed narrower esophageal diameter and milder inflammation than the control rats. At 40 weeks, the incidence of Barrett's esophagus was similar between control and sulindac-treated groups, but the incidence of adenocarcinoma was significantly lower in the 1000ppm sulindac-treated group than either the control or 500 ppm sulindac-treated groups. COX-2 was significantly increased in the lower esophagus of control rats killed at 40 weeks. Cyclin D1 expression was negligible in the sulindac- treated group compared with the control group. CONCLUSION: We suggest that the chemopreventive effect of sulindac is related to decreased COX-2 and cyclin D1 expression, which may be influenced by reduced inflammation.

This study was performed to evlauate the usefulness of red ginseng extract as an adjuvant therapeutic agent to improve immune function in immune compromizing gastrointestinal carcinoma patients. We treated 48 patients with two regimens after we undertook the curative resection for gastrointestinal carcinoma: 1) only chemotherapy and immunotherapy (control group), 2) chemotherapy and immunotherapy with 4500-5400mg red ginseng for 6 months (study group). For investigating the immunologic alternations alongside the numerical changes in peripheral blood lymphocyte and their subsets in the gastrointestinal carcinoma patients, lymphocyte surface markers were determined by monoclonal antibodies on the preoperative 1st day, and postoperative 5th day, 1 month, 3 month and 6 month in 28 controls and 20 red ginseng groups in gastrointestinal carcinoma patients which were recruited at Korea University Hospital from March, 1995 to December, 1995. The mean value for body weight was increased in the ginseng group than in the control group. There were no significant differences of serum hematocrit, hemoglobin, total protein and albumin in both groups. The total lymphocyte count was much more increased in the ginseng group than in the control group. The number of T cell, B cell, CD8, CD4, NK cell and activated T cell were increased in ginseng group more than in control group. The T cell was significantly increased on postoperative 5th day, 3 month and 6 month, and B cell on postoperative 6 month in ginseng group than in control group. The CD8 was significantly increased on postoperative 3 month and 6 month, CD4 on postoperative 5th day, and NK cell and activated T cell also on postoperative 6 month in ginseng group than in control group. In conclusion, red ginseng may be useful as a longterm adjuvant therapeutic agent for improving the immune function and anticarcinogenic effect after curative operation for immune compromizing gastrointestinal carcinoma patients.

Magnetic resonance imaging(MRI)has proved to be a valuable method for evaluation of the head and neck. Unfortunately, metallic devices associated with certain dental fillings and applicances often cause variable artifacts that can obscure normal or pathologic conditions on MR and computed tomography. In this work, we assessed the MR appearance of dental prosthetic materials in vitro and in vivo including precious alloys. Nonprecions alloys, resin, amalgam and titanium alloy, For in vivo studies, these materials were placed in healthy volunteer's mouths and then images were assesed. Analyis of the appearance of shape and extent of artifact,and observed influence of these artifacts on the image interpretation at 0.2 Tesla permanent type MR scanner were valuated. Material used as temporary or permanent filling of crowns such as amalgam. precious alloy and, microfilled resin did not cause artifact on the image. The size of the artifact produced by the nonprecious alloys was influenced by the ferromagnetism of the object and the volume prosthesis, and was related to the scanning sequence. Nonprecious alloys produced minimal local signal distortions, where precious alloys, and dental resin had no effect on the MR image in vivo. These results were mainly from a low field strength MR scanner used in this study.
