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.

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.

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.

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.

BACKGROUND: Group A streptococci (GAS) cause various infections in the school children. The change of isolation rate of GAS between time interval was observed by repeated throat cultures and acquisition rate of new strain was investigated by comparing the serotypes of GAS. METHODS: Throat cultures were taken from the school children in Chungnam and Seoul. Second throat cultures were taken from 119 children in Chungnam after 1 month and from 59 children in Seoul after 4 months, who showed GAS in the first throat culture. Serotypings such as T, M and opacity factor typing were performed and compared against 40 children in Chungnam and 26 children in Seoul who grew GAS in both throat cultures. RESULTS: GAS were isolated from 57.1% (68/119) in Chungnam and 45.8% (27/59) in Seoul in the second throat culture. Different serotypes between first and second throat culture were 5 of 40 (12.5%) in Chungnam and 4 of 26 (154%) in Seoul, respectively. CONCLUSIONS: Almost half of children contained GAS continuously until 4 months and acquisition rate of new serotypes was 14.0% during this time. When GAS is repeatedly isolated, serotyping was very useful to recognize whether the strain is same or not.
