We tried to analyze the status of 10 units of frozen thawed apheresis platelet concentration by 6% DMSO method for the evaluation of practical applicability. The platelet concentrations were transferred to PL-732(Baxter, USA) cryopreservation bag, and DMSO is added to those bag at slow rate until expected final 6% concentration is achieved, thereafter those were directly placed to -80 degrees C refrigerator for freezing. Someday later from I week to 1 month, those were thawed at 37 degrees C water bath, and then washed by same volume of ABO matched plasma. In the course of cryopreservation, about 7% of platelets were lost and the mean recovery rate of platelet was 93% compared with those of unfrozen status. LDH, the values of platelet lysis, and pH were within normal limits, whereas platelet aggregation test shows decreased aggregation to collagen and ristocetine compared with those of unfrozen status(p<0.05) but they were clinically acceptable. We suggest that the frozen platelets may be useful in a some clinical situation such as hematologic malignancy and solid tumor by autologous transfusion.

BACKGROUND/AIMS: The use of diagnostic laparoscopy has been changed because of the development of lesser invasive radiologic tools, which is more useful in the diagnosis of diffuse liver diseases recently. The aim of this study was to evaluate the clinical value of laparoscopy in diagnosis of diffuse liver diseases during laparoscopic surgery and to find the relationship between laparoscopic gross finding and liver biopsy. METHOD: Sixty-five patients were performed laparoscopic cholecystectomy from March 1. 2001 to July 30 . 2001. We prospectively compared the result of liver biopsy with preoperative serum liver function test, ultrasonographic finding and liver surface characteristics as observed during laparoscopic surgery. RESULTS: The results of liver biopsy obtained in 59 cases were normal liver; 57.6%, mild steatosis; 15.4%, moderate to severe steatosis; 16.9%, chronic liver disease; 1.5%, cholangitis; 3.1% and cirrhosis; 1.5%. There was no correlation between preoperative liver function test and liver biopsy. However, the ultrasonographic finding was more correlated with liver diseases. The sensitivity of laparoscopic liver surface characteristics was 76.0%. The liver surface characteristics was well correlated with liver biopsy finding, especially in color of liver surface and contuor of liver margin. Importantly, when one more abnormal findings in liver surface characteristics were found, the positive predictability of liver disease was 56%. CONCLUSIONS: Diagnostic laparoscopy is a safe and accurate method for evaluating the diffuse liver diseases. If the abnormal findings of liver surface characteristics is found during laparoscopic surgery, one shoud confirm liver disease by liver biopsy.

Ectopic pregnancy is a common medical problem that is difficult to diagnose and potentially may lead to significant mortality or morbidity. The incidence of ectopic pregnancy is definitely increasing due to the rise in pelvic inflammatory disease (PID), pelvic surgery, intrauterine device (IUD), and assisted reproductive technologies, such as in vitro fertilization and embryo transfer (IVF-ET). Combined ectopic gestations are much rare and their true incidence is unknown. Multiple ectopic gestations may occur in a variety of locations. The majority involve one or both fallopian tubes. We report a case of combined tubal and cervical pregnancies, and discuss their management.

PURPOSE: To learn the long-term prognosis of patients with deep vein thrombosis (DVT), we evaluated the location and extent of thrombotic changes, hemodynamic status and clinical symptoms of patients of more than 12 months after development of acute thrombosis. METHODS: 31 patients (man; 24, female; 7, mean age; 44.7 13.2 years) with phlebograpically documented DVT were followed-up for 13~90 months (mean: 32.6 20.4 months) with Duplex scanning, and photo-plethysmography (PPG), and clinical symptoms. To evaluate the effects of treatment modality, the patients were devided into 3 groups; Group 1 (heparine warfarin, n=17), Group 2 (heparine warfarin catheter directed urokinase, n=10), Group 3 (heparine warfarin systemic urokinase, n=4). But, the size of Group 3 was inappropriate to compare with other groups, we performed analysis of the results of Group 1 and 2. RESULTS: Remained thrombi were detected in 22 patients (70.2%) of 31 patients by Duplex scanning, even 1 year later. Of the 29 patients studied with PPG, 24 patients (83%) revealed valvular incompetence in deep (11 cases, 38%) and superficial venous systems (13 cases, 45%). Thrombolytic rate in Group 2 was much higher than Group 1; complete resolution (40% vs 23%), complete obstruction (0% vs 41%). The statistically significant correlation between resolution degree and symptomatic improvement was shown (p=0.008). CONCLUSION: Residual thrombi and valvular damages after DVT were common. But, thrombolysis by catheter-directed urokinase may be associated with a higher rate of thrombolysis and clinical improvement. Anticoagulation alone may not be a sufficient method for treatment of DVT.

BACKGROUND: In Korea, a screening panel of cells from abroad without Di(a) positive cells has been commonly used when a patient has an unexpected antibody screening test. It has been reported that Di(a) occurs with a frequency of 6.14 to 14.5% among Koreans. However, the current popular antibody screening panels contain no Di(a) positive cells. In this study, we evaluate the clinical usefulness of the Di(a) Cell Panel (Diagnostic Grifols, Barcelona, Spain) for Koreans. METHODS: A total of 3,372 pretransfusion samples were employed for unexpected antibody screening testing using panels of cells by the DG Gel microtube column agglutination system, including additional Di(a) cells (Diagnostic Grifols, Barcelona, Spain). The positive cases in this system were confirmed again with DiaMed Di(a) antigen positive panel cells (DiaMed Ag, Cresssier, Morat, Switzerland) and this was followed by sequence- based Diego genotyping. RESULTS: The positive detection rate of an unexpected antibody screening test using SeraScan Diana I and II was 1.07% (36/3372), and seven samples were reactive (1+~2+) with the SeraScan Di(a) panel cells (0.21%). However, among the 5 available genotyped samples, two cases were typed as Di(a-b+). CONCLUSION: Even though there is discrepancy between the genotype and the two antibody screening kits, the addition of Di(a) positive cells as unexpected antibody screening panel cells is recommended.

BACKGROUND: Left ventricular hypertrophy is common in chronic renal failure patients and may contribute increased risk of cardiovascular morbidity and mortality. We evaluated the left ventricular morphology and function in renal transplant recipients to find the relationship between hemodynamic changes and morphologic and functional improvement after transplantation. METHODS: Serial echocardiographic evaluations were performed in 27 adults(20 men and 7 women) at the time of transplantaion and posttransplantation 1 month and 4 months. The average duration of hemodialysis was 16+/-24 months(mean+/-S.D.). RESULTS: At the time of transplantation, the hematocrit level was 21+/-6% and posttransplantation 1 month and 4 months, that was increased to 39+/-5% and 42+/-7%, respectively(p<0.001). Left ventricular mass index by echocardiography was decreased significantly from 246+/-87g/m2(pre-KT) to 169+/-38g/m2(post-KT 1 month) and 153+/-40g/m2(post-KT 4 months), respectively (p<0.001). Interventricular septal thickness and left ventricular posterior wall thickness were decreased significantly after 4 months of transplantation. Left ventricular systolic and diastolic dimensions were also decreased significantly after 1 month and 4 months of transplantation. Left ventricular volumes and cardiac output were also decreased significantly. But A/E ratio, ejection fraction and fractional shortening did not change significantly. CONCLUSION: These findings showed that pretransplant high output state was resolved radipidly(within 1 month) but the diastolic function did not improved after transplantation 1 month and 4 months.

BACKGROUND: The cryopreservation of Red Blood Cells have been proved to have many advantages in western countries. However, in Korea, clinical application of frozen-thawed blood is still in its early stage. We tried autologous frozen-thawed blood transfusion and evaluated the effects and complications. METHODS: Nine units of whole blood were collected from the autologous (n=1) and allogeneic bone marrow donors (n=3) and made packed RBCs by a centrifugation method. We made frozen RBCs using high glycerol method and stored them in -80degrees C freezer for 1 month. Eight units of frozen RBCs were thawed and washed by Cobe spectra (Cobe, USA). Autologous transfusions were done to the patient and donors while the bone marrow collection procedures were in process for bone marrow transplantation and we carefully observed its effects and complications. RESULTS: The mean RBC recovery rate were 89.8% and the supernatant plasma hemoglobin, K+, LD, osmolality, and simulation test were satisfactory to the allowable limit. After transfusion, the hemoglobin value was significantly elevated being comparable to that of the fresh blood. A case showed mild hematuria related to this transfusion but soon it disappeared in a day. CONCLUSION: The autologous frozen-thawed blood transfusions were safe and as much effective as the fresh blood. It would be essential to have skillful techniques in post-thaw washing process.

BACKGROUND: The diagnosis of malaria has been usually made using microscopic examination of Wright stained thin blood films in Korean army. This method is labor-intensive, time consuming and requires the microscopic expertise. Therefore, the alternative techniques, rapid diagnostic test, have been sought for use in Korean army. We performed a comparison of the OptiMAL test with GENEDIA Malaria (P. vivax) Ab Rapid I, II to assess its sensitivity and specificity of Plasmodium vivax malaria. METHODS: Blood specimen were collected from 51 patients who were presented and initially diagnosed for P. vivax by the microscopy of blood smears and from 30 control patients without malaria infection at the Capital Armed Forces General Hospital (CAFGH) between October 2000 and February 2001. Among the 51 patients, we also collected 24 samples from 24 patients at 2 or 3 days after therapy. The OptiMAL test and GENEDIA Malaria (P. vivax) Ab Rapid I, II were performed according to the manufacturer's instructions on all samples respectively. RESULTS: Compared with the blood film, sensitivities and specificities of the OptiMAL test, GENEDIA Malaria (P. vivax) Ab Rapid I and GENEDIA Malaria (P. vivax) Ab Rapid II were 94.1~100% (29/29), 80.4~83.3%, 96.1~96.7% respectively. One case was interpreted as 'undetermined' by OptiMAL test. In 24 patients during therapy, the sensitivities of the OptiMAL test, GENEDIA Malaria (P. vivax) Ab Rapid I and GENEDIA Malaria (P. vivax) Ab Rapid II on 8 specimens with mean 120/microliter parasitemia and 16 specimens with negative parasitemia were 75~43.8%, 87.5~81.3%, 100~100% respectively. CONCLUSION: Our data demonstrated that the sensitivity and specificity of the GENEDIA Malaria (P. vivax) Ab Rapid I were not satisfactory, but the sensitivity and specificity of the OptiMAL test and GENEDIA Malaria (P. vivax) Ab Rapid II were relatively high and useful diagnostic tests for diagnosis of P. vivax in areas like the militaries where laboratory facilities are poor or non-existent.
