BACKGROUND: Detection of anti-Kidd antibody is important because of its clinical significance. If detection is difficult due to weak serological reactivity or dosage effect, use of an enzyme method could be helpful. However, despite use of an enzyme method, we still observed weak reactivity of anti-Kidd antibody. METHODS: All identified anti-Kidd antibody cases from Jan 2012 to Aug 2015 in Asan Medical Center were reviewed. Antibody identification test was performed using the column agglutination technique using Bio-Rad ID-DiaPanel with LISS/Coombs card, Bio-Rad ID-DiaPanel-P with NaCl/Enzyme card, and ID-DiaPanel-P with LISS/Coombs card. The test results were compared. RESULTS: Sixty cases of anti-JK(a) or anti-Jk(b) were detected and tested by enzyme method. Among them, 34 (56.6%) cases showed strengthened reactivity using the ID-DiaPanel-P with NaCl/Enzyme card method. However, 26 (43.4%) cases showed weakened reactivity. Of these, 13 cases that could be tested by an additional method using ID-DiaPanel-P with LISS/Coombs card containing anti-IgG and anti-C3d showed successfully strengthened reactivity. CONCLUSION: The reactivity of anti-Kidd antibodies that was not strengthened using ID-DiaPanel-P with NaCl/Enzyme card method could be successfully strengthened by use of the ID-DiaPanel-P with LISS/Coombs card.

BACKGROUND/AIMS: Gastric polyps are recommended to be removed due to their premalignant potential. Endoscopic polypectomy has long been considered a safe and effective method for removal of gastric polyps. METHODS: The authors diagnosed and treated 290 gastric polyps using endoscopy on 210 patients who had been admitted to Chungnam National University Hospital from January, 1990 to August, 1996. The clinical endoscopic and pathologic findings were evaluated.

Gastrointesinal polyp is a premalignant lesion, it is recommanded to be removed. Endoscopic polypectomy has long been considered as a safe and effective method for removal of polyps. One hundred forty eight endoscopic gastrointestinal polypectomy were done in 111 patients who visited Chungnam National University Hospital from January in l991 to August in l993, and clinical character including histopathology were evaluated.

PURPOSE: .In FSRT (Fractionated stereotactic radiotherapy) planning, we studied the usefulness between multiple arc FSRT and conformal FSRT by comparing tumor shape and DVH(dose volume histogram). MATERIALS AND METHDS: In Chungnam Univ. hospital, we had treated the sixteen patients with FSRT from Aug. 1997 to Dec. 1998. In choosing multiple arc FSRT or conformal FSRT, we had considered multiple arc FSRT if tumor shape was similar to sphere or the value of IF was less than 1.25, conformal FSRT if tumor shape was very irregular or IF was more than 1.3. For evaluation of treatment planning, we had considered the appropriate DVH for tumor volume and for critical organs. RESULT: The errors between reference point and the coordinates point on AP, Lat radiography were less than 1 mm before treatment. We had planned 3~5 arcs for multiple arc FSRT, 5~6pots for conformal FSRT. The mean dose distribution of tumor volume of cumulative DVH between multiple arc FSRT and conformal FSRT was 90.6, 86%, respectively. The dose of critical organs irradiated was less than 5% maximum dose of cumulative DVH. CONCLUSION: We had obtained the similar value between multiple arc FSRT and conformal FSRT, so that we had appropriate treatment planning of FSRT for multiple arc FSRT and conformal FSRT according to tumor shape and size.

The preoperative serum level of tumor marker CA 125 has served as rough orientation in making the distinction between a benign and a malignant adnexal mass or as a reference for monitoring the success of therapy. But there were some reports suggesting that the stage of the disease and tumor grade, which are known to be the independent prognostic factors in ovarian cancer patients, may exert an influence on the preoperative CA 125 level. In this retrospective study we analysed the significance of preoperative serum CA 125 level with respect to tumor grade and tumor stage. Between June, 1989 and January, 1997, 82 patients with epithelial ovarian cancer managed at Asan Medical Center were evaluated, in whom serum level CA 125 were measured preoperatively. Tumor grade bears no meaningful influence on the preoperative CA 125 level, and also the correlation is low and statistically insignificant (r=0.12, p=0.29 in all stages; r=0.01, p=0.97 in stage I; r=-0.09, p=0.83 in stage II; r=0.06, p=0.72 in stage III; r=0.25, p=0.41 in stage IV). There was no significant effect of FIGO stage on preoperative CA 125 level (r=0.21, p=0.06 in all grades; r=0.32, p=0.10 in G1; r=0.08, p=0.74 in G2; r=0.17, p=0.30 in G3). However, we found a significant correlation between FIGO stage and tumor grade (r=0.45, p<0.01). In conclusion, our data suggests that both tumor grade and FIGO stage have no significant effect on preoperative serum CA 125 level.
