The major therapeutic human serum albumin was purified into three batches by cold ethanol precipitation method and albumin were studied for the stability. In storage over 39 months, the pH of albumin was slowly acidified from pH 7.0 to pH 6.8. The turbidity was not changed. However, the heme content in albumin was progressively increased with time in storage. Therefore, the color of albumin changed after 1-year of storage. The polymer and aggregates was investigated by HPLC techniques. The HPLC analysis are compared with the polymerization. The polymer form of albumin was increased during storage after the preparation. It is suggested that the denaturation of albumin is not dependent in temperature but dependent increased in fatty acids during storage. The results passed all the internal specifications at the albumin during the tentative expiration.

The auther investigated HBeAg and anti-Hlse in 1,000:> cases(male 941,female 59) of HBsAg positive among the 225,512 blood donors in Seoul Nambu blood center in 1994. HBeAg and anti-HBe was detected by the method Enzyme Immunoassy. The results obtained were as follows; 1. HBeAg and anti-HBe positive rates were detected 498 cases (49.8%) and 447 cases (44.7%) respectively among 1,000 cases HBsAg positive blood donors. 2. In HBsAg positive carriers, HBeAg positive rates were not significantly different between anti-HBe positive rates.but in sex were significantly different between HBeAg positive rates and anti-HBe positive rates. 3. HBeAg positive 4 cases were analyzed with age and it was found percentages of positive rates were from 16 to 19 63.8%,from 20 to 29 53.6%,from 30 to 39 21.1%,from 40 to 49 31.0% and age above 9) 8.3% but anti-HBe positive 447 cases were from 16 to 19 32.8%,from 20 to 29 40.6%, from 30 to 39 69.7%, from 40 to 49 77.8% and age above 50 91.7%. 4. HBeAg positive rate decreased stepwise with age, while anti-HBe positive rate increased stepwise with age. 5. The ALT T level of 851(85.1%) of the total 1,000 cases were less then 45 IU/L,(normal). When 397(46.6%) were found HBeAg positive, 407(47.8%) were found anti-HBe positive, 9(1.0%) were found both positive, 38(4.5%) were found both negative.and 149(14.9%) were ALT`` level above 45 IU/L(abnormal), when 101(67.8%) were found Hl3eAR positive. 40(26.8%) were found anti-HBe positive,4(2.7%) were found respectively both posithve and both negative.

저자들은 일상 혈액형 검사에서 혈구형 검사만을 실시할 경우 발견할 수 없었던 cis-A2B3형 아버지와의 A1형 어머니 사이에서 O형의 아들이 출생된 cis-AB형 가계를 경험하였기에 문헌고찰과 함께 보고하며 수혈검사시 ABO식 혈액형에서 필히 혈구형과 혈청형을 실시하여야 할 것임을 제안하고자 한다. ABO discrepancy is difficult to inspections of one`s child confirmation and transfusion. Cause of ABO discrepancy have several of things and the authers introduced 1 case of the causes to you. ABO blood group is determinated by A and B genes located on each chromosomes which are inherited from parents.But cis-AB has been reported unusual inheritive of A and B genes on the same chromosome. By a routine blood typing, we have found that parent of cis-A2B3 type and A1 type can bear children of O type blood. From the fact above-mentioned, we have concluded that the above case cannot be predicted from Mendel`s laws. Therefore, We intend to report the truth with the conference books and propose that medical technologist must be tested cell and back typing certainly pretransfusion test.

After test the blood samples donated by 33,838 Koreans with Lucky HCD, 3rd generation Hepatitis C diagnostic reagent, using ELISA method, We selected the samples found positive and retest them with Lucky HCD confirm, which is the diagnostic reagent confirming Hepatitis C in Immunoblot method and achieved the following results. 1. Among blood doner 33,838, 133 which is equivalent to 0.39 % of the total were found anti-CV positive. Among the male, 31,023(92 %), 126 which is equivalent to 0.41 % were found positive. Among the female 2.815(8 %), 7 which is equivalent to 0.25 % were found positive. 2. When tested 133 which were found positive by ELISA method with Lucky HCD confirm in order to confirm the test results, 40(30 %) were found positive, 93(70 %) were false positive, 17(3 %) were indeterminate, and 76(57 %) were negative. Summarizing from the total blood donors, 0.12 % were anti-HCV and the false positive percentage except indeterminate were 0.22 %. 3. The ALT value of 32,159(95 %) of the total blood donors were less then 45IU/L(normal). When 32,159 were tested with HCD3.0, 109(0.34 %) were found anti-HCV. When 109 were rested with Lucky confirm, 24(0.07 %) were found positive. 771(2.3 %) of the total blood donors were having ALT value from 46 to 59 IU/L. When 771 were tested with HCD3.0, 8 were found positive. When 8 were retested with Lucky confirm, 3(0.39 %) were found positive. 908(2.7 %) of the total donors were having ALT value above 60IU/L. When 908 were tested with HCD 3.0, 16(1.76 %) were found positive. 16 were retested with Lucky confirm, and 13(1.43 %) were found positive. These statistics show that the potential percentage of HCV positive grows in the proportion of the ALT value. As shown above, the substantial quantity of the blood donated are presently decided false positive by the Hepatitis C Antibody test using 3rd generation ELISA method in the Red Cross Blood Center and destroyed. By noticing such results to the blood donors having goodwill, The Red Cross might lose it`s faith for testing the blood and it will eventually affect the controlling the blood donors To supplement the current testing system, we consider that we need to have final confirm test at the end of the test procedure before release the test results.

배경 : 1회 혈장 헌혈량을 항응고제가 포함된 500mL와 순수 혈장 500mL(항응고제 포함 500mL 이상)로의 이원화 필요성이 제기되고 있다. 혈장 성분 채혈에 있어서 순수 혈장량 500mL를 도입하기 전에 기존 채혈량 500mL를 채혈하는데 따른 차이를 비교하여 헌혈자의 안전을 확보하기 위해 본 실험을 실시하였다. 방법 : 제 I군은 항응고제를 포함해서 500mL의 혈장을 채집한 남성 115예, 여성 78예로 하였고, 제 II군는 헌혈자의 동의를 받아 순수 혈장 500mL(항응고제 포함 500mL 이상) 채집한 남성 108예, 여성 62예로 하였다. 헌혈자 두 군의 헌혈 전, 후 혈압, 맥박과 Hct., 혈장 총단백을 측정하였고, 각 성분채혈기별 비교와 헌혈자에서 나타난 부작용, 혈장제제 1단위당 신선 혈장의 양 등을 비교하였다. 또한, 혈장 헌혈 때 드물게 발생할 수 있는 부작용은 혈장성 분헌혈 시행 과정 또는 후에 관찰하였다. 결과 : 1. 제 I 과 제 II군의 두 군 사이의 연령과 남성 체중의 유의한 차이는 없었으며, 헌혈 전, 후의 혈압, 맥박, Hct.와 총단백량도 유의한 차이를 보이지 않았다(p>0.05). 2. 성분채집기 3종을 중심으로 두 집단간의 헌혈후 각종 모니터 수치를 비교해 보았는데 체외순환 혈액량, 항응고액과 혈장량, cycle 및 소용시간 등에서 유의한 차이를 보였다(p<0.05). 3. 두 군 모두에서 특별한 헌혈 부작용은 없었다. 결론 : 국내 혈장 자급자족에도 도움이 되며, 헌혈자에게도 특별한 부작용이 나타나지 않는 점을 고려해 볼 때, 혈장 채혈량을 항응고액 포함 500mL 용량과 순수 혈장 500mL 용량(항응고제 포함 500mL 이상)으로 하는 이원화 방안을 제시해 본다. Background : It has been proposed that the amount of donated plasma should be differentiated according to the volume of plasma collected ; 500mL of donated plasma including anticoagulant versus 500mL of pure plasma (over 500mL, when it includes anticoagulant). The purpose of this study was to evaluate whether the increase of donated plasma volume would have any adverse effects on donor safety. Methods : According to the volume of plasma collected donor w r divided into group I (500mL of plasma including anticoagulant) and group II (500mL plasma only; more than 500mL if anticoagulant is included). Group I and II comprised 115 and 108 men and 78 and 62 women, respectively. Pre- and post-plasmapheresis of blood pressure, pulse, hematocrit, and total protein were compared between the two group. In addition, parameter of apheresis instruments used and occurrence of adverse reactions du to increased plasma collection were evaluated. Results : 1. Regarding age, body weight of male donors, and pre- and post-plasmapheresis of blood pressure, pulse, hematocrit and total protein, no significant difference was observed between the two groups (p>0.05). 2. Parameters of apheresis instrument (extracorporeal

The effect of rapid cooling to 20~24℃ of whole blood immediately after collection, using'cooling unit' minimized damage of platelet function and yield high anticoagulant factor in the plasma. Though, Ice pack, a sort of cooling units, was proved inadquate to preserve platelet concentration because of hard cooling force. In comparison between cooling faculty experiment of foreign and national cooling unit, it has been shown similar to the dissolved and frozen changing point. In case of preservation whole blood 4 units per cooling 1 unit, it has been shown cooling down below 24℃ in 1 hour 40 minute and can be maintained 20℃ above 8 hours after blood collection. From the above literature, national cooling unit, substituted foreign cooling unit, has not special problem. Therefore, the author conclusioned hat using cooling unit contribute to quality improvement of blood and standardization of the subsequently prepared blood components and will diminish processing at irregular hour or season cause.
