In the 88 cases of biliary disease, which was proven in Seoul Red Cross Hospital from Jan. 1980 to Dec. 1981,comparative studies were made with oral and IV cholecystocholangiographic findings and ultrasonographic findings.The resuslts were ; 1. In the 18 cases of GB stones, there are 17 cases (94.4%) of positive findings incholecysto-cholangiography with detection of stone in 7 cases (38.9%), while in sonographic study, 16 cases(88.9%) are shown positive findings with detection of stones in 11 cases (61.1%). 2. In the 17 cases of acalculouscholecystitis, the diagnostic accuracy is 88.2% in cholecystocholangiography and 64.7% in sonography. 3. In the 7cases of CBD stones, all cases are shown positive findings in cholecystocholangiography with detection of stone inonly one case (14.3%), while 6 cases (85.7%) of positive findings are shown in sonography with detection stone inall cases. 4. I.V. cholanagiography is more accurate diagnsotic procedure rather than oral GB study in the casesof poor or non-functioning GB. 5. Sonography is the choice of procedure in the diagnosis of stones, while in thecases of colecystitis, cholecystocholangiography is more useful diagnostic procedure.

BACKGROUD: The blood component should not be issued for transfusion if there is any abnormality in color or physical appearance, or any indication of contamination. During 3 years (1999-2001), 1,041 blood components were returned to Central Red Cross Blood Center from the hospitals because of various reasons. We Analyzed the frequency and reasons of blood component returns for the useful information of blood supply plan. METHODS: Each blood component return in the Blood Component Return Report from 1999 through 2001 was examined for the number of units and return reasons. RESULTS: For 3 years, the total number of supplied blood components were 1,203,573 units and 1,041 (0.09%) of them were returned from 26 hospitals. The most common reason of return was broken bag or pilot tube (70.9%). Other reasons were fibrin(or precipitates) in bag (3.0%), clots in pilot tube (2.9%), turbid plasma (1.8%), hemolysis (0.5%), icteric plasma (0.3%), label errors (1.1%), incompatible cross matching (0.2%) and others (0.7%). Also there were blood returns due to poor handling of blood components in hospital (1.9%) and reasons unrelated to blood safety, purity and potency such as rare blood (5.8%), exchange for fresh blood (9.8%) and unused blood (1.2%). The most commonly returned blood component was plasma component (69.5% of units) CONCLUSION: The final product should be inspected prior to issue with more strict standard. And the proper system for assurance of returned normal blood components from hospitals must be applied for efficient blood utilization.

This series represents 128 cases of acute gonococcal urethritis treated with doxycycline at the Seoul Red Cross Hospital from the 1st. May to.5th, Oct., 1969. Results of this treatment were divided in three groups: Group I ; Single dose of doxycycline, 300 mg. was administered for this group. 36 cases fall into this category. Cure rate for this group was 36%. Group II; Doxycycline, 200mg. was given on the 1st treatment day and daily dose of 100 mg. for 4 ensuing days. 42 cases were included to this group. Cure rate was 72%. Group III Daily dose of 200 mg. was administered for the remainders, 50 cases for 5 consecutive days. Cure rate was 91%. It was concluded that 200 mg. of doxycycline daily for 5 days dose regime can be recommended for the treatment of acute gonococcal urethritis, especially in cases allergic to penicillin or in which penicillin treatment fails. No anaphylactic shock or some other undesirable side reaction in administering this drug was experienced.

BACKGROUND: An unexpected antibody screening test with panel cells from abroad without Dia positive cells is common practice in most laboratories in Korea, although it is impossible to detect anti-Dia. Our laboratory have used DiaCell Dia (DiaMed Ag, Cressier, Morat, Switzerland) as one of antibody screening panel cells and only positive samples with DiaCell Dia cells have been also confirmed with Dia antigen positive panel cells from Korean Red Cross (KRC). In this study, the experiences and clinical usefulness of DiaCell Dia were evaluated. METHODS: The 26,102 pretransfusion samples were tested by DiaMed microcolumn gel assay using the LISS/Coombs card, ID-DiaCell I, II, and DiaCell Dia. The DiaMed microcolumn gel assay using the LISS/Coombs card has been used for unexpected antibody screening test with panel cells from KRC. RESULTS: The positive detection rate of unexpected antibody screening test using ID-DiaCell I and II was 0.58%(151/26, 102), and eleven samples were reactive (1+~2+) with DiaCell Dia panel cells (0.04%). However, only six(0.02%) of 11 samples were reactive(2+) with Dia positive cells from KRC. CONCLUSION: The discrepant detection rate for unexpected antibody with Dia panel cells between from DiaMed and KRC is supposed to need further study. The addition of Dia positive cells as an unexpected antibody screening panel cells is strongly recommended in case that antiglobulin phase of crossmatch is abbreviated for unimmunized patients.

BACKGROUND: Active re-donation is important for the whole blood donation program. Preparation of the blood-collection environment to minimize vasovagal reaction (VVR) is very important because VVR is the most common factor for stopping re-donation. METHODS: From the 1st of January to the 30th of November in 2005 at Busan Red Cross Blood Center, a total 195,247 donations from 138,093 donors were investigated for VVR. RESULTS: The total frequency of VVR was 0.14%. The frequency of VVR of the group donors who donated in indoor collecting places was the highest and the next highest VVR frequency was for the outdoor donors group. Unexpectedly, the frequency of VVR was the lowest in donors who donated in a blood bus. Teenage donations of blood were most frequent, and the next were people in their twenties. The frequency of VVR was the highest in first-time donor group. The more blood donated, the less the subjects experienced VVR. CONCLUSION: To recruit and retain the blood donors, the blood collection environment should be reconsidered for the group-donors in indoor- or outdoor places and not for those in the blood bus. In these places, it is important to educate the staff and prepare the blood-collecting environment where individual attention can be given to donors of the high-risk group for preventing VVR.

BACKGROUND: For the antibody screening test, the classical LISS tube indirect antiglobulin test has been replaced by the microtube column agglutination system in Korea. This system was first created in 1990 by Lapierre and it is distributed through DiaMed (DiaMed Ag, Cresssier, Morat, Switzerland) around the world. Similar systems, such as Ortho BioVue, have been developed and competed after that. We evaluated a newly developed microtube column agglutination system, DG Gel (Diagnostic Grifols, Barcelona, Spain), and we compare it with the other established systems. METHODS: In a comparative study, a total of 126 samples, including 76 antibody screening positive samples and 50 negative samples, were tested in parallel by the LISS/Coombs card (DiaMed Ag, Cresssier, Morat, Switzerland) and the DG Gel microtube column agglutination system. The positive samples that were proved by the LISS/Coombs card and the DG Gel system were identified by the ID-Dia panel (DiaMed Ag, Cresssier, Morat, Switzerland) and Identisera Diana (Diagnostic Grifols, Barcelona, Spain). Discrepant samples were rechecked with I, II and III cells that were supplied by the panel of the Korea Red Cross Blood Center. RESULTS: Among the 126 samples, the DG Gel antibody screening system showed 98.7% (75/76) sensitivity and 100% (50/50) specificity. We obtained concordant results in 75 samples (98.7%) and discrepant results in one sample (1.32%) between the DG Gel and DiaMed-ID for antibody identification. CONCLUSION: Both the microtube column agglutination systems work well and showed high estimated sensitivity and specificity with high concordance. Therefore, the DG gel microtube column agglutination system can be used with good results.

BACKGROUND: Leukocyte reduction filters are widely used to prevent transfusion reactions caused by leukocytes in blood components. Commercial filters are not sufficient for removal of leukocytes for prevention of transfusion associated graft-versus-host disease; therefore, irradiation of blood components was performed using expensive equipment. Techniques using an aptamer substituted for antibody have been developed and are available in clinical areas. The purpose of this study is to develop the aptamer filter system and to evaluate its efficiency and the possibility of its clinical application. METHODS: Aptamers targeted to CD45 were selected by the Postech Aptamer Initiative. The aptamer filter in which aptamers attached to beads were bound to leukocytes and removed by magnetic field was developed. Filtration of 14 units of leukoreduction-red blood provided by Korean Red Cross Blood Services was performed using aptamer filters. Leukocyte removal rate and red cell recovery rate were evaluated and bacterial culture was performed. RESULTS: After filtration using the aptamer filters, 45.6% of leukocytes were additionally removed and the red cell recovery rate was 92.8%. No growth in the bacterial culture was observed. CONCLUSION: In order to apply the cell depletion technique utilizing an aptamer to blood filter system, we developed and evaluated the aptamer filter system. Through improvement of the binding efficiency of the aptamer and the filtering process, and application of the various aptamers for other different cells, we suggest that this technique can be applied in the clinical area, such as a substitution for the irradiation process for TAGVHD prevention.
