Retrospective studies suggest that rreasurernent of maternal serum unconjugated estriol, in combination with maternal serum human chorionic gonadotropin (hCG) and α-fetoprotein provides an effective method of prenatal screening for Down syndrome. The median maternal serurn unconjugated estriol is lower in pregnancies with a Down syndroræ fetus Comparative evalution studies concerning magnetic separation method reagent and coation tube method reagent were conducted the SAMKWANGREFERENCE LABORAT-ORIES The results were summarizes as follows: 1. in 380 matemrnal serum at 14 to 2 weeks gestraion uE3 level is near to overall mean (Table 1.2 figure 1.2) 2. The data of magnetic separation method were correlated well with coating tude method (r=0.8564). .

The purpose of this work lies In the design of controllers which have the ability to effectively control the rotational velocity of the axial piston motor. The hydrostatic drive equipment consists of swash-plate-type axial piston pump and motor equipped with proportional control valves. As a load system we attached a fly-wheel to the motor shaft. First of all, the rotational velocity of axial piston motor was measured by fixing the swash angle of the axial piston motor varying the angle of the axial piston pump and we obtained the static characteristic curve relating the axial piston pump and motor. Using this characteristic curve, a program was written via Labview7.1 which can control the rotational velocity of the axial piston motor by adjusting the swash angle of axial piston pump. We studied the dynamic characteristics of the hydrostatic drive system in order to investigate how the controller well controls the rotational velocity of the piston motor.

조윤교,최삼규,서소연,신용환,Cho, Youn-Kyo,Choi, Sam-Kyu,Seo, So-Yeon,Shin, Yong-Hwan 대한핵의학기술학회 2011 핵의학 기술 Vol.15 No.1
Glucagon은 췌장 Langerhans섬 ${\alpha}$-세포에서 합성 분비되며, 기능으로는 간 당원분해, 지방분해, 인슐린분비 촉진 작용 등이 있다. Glucagon의 측정은 Glucagon 과잉증에 의한 당뇨병, 특발성 Glucagon 결손증, 불안정 당뇨병에서 저혈당의 진단을 하기위해 실시된다. Glucagon 측정시 세 가지 주의를 요하는데, 첫째, Aprotinin이 첨가된 EDTA tube에 채혈해야 하고 둘째, Plasma를 분리하여 Glass tube에 냉동 보관하여야 하고, 마지막으로 검사시에도 Glass tube에서 측정을 해야 한다. 이에 우리는 EDTA tube에 Aprotinin의 유무에 따른 결과 비교, 검체 보관 용기의 차이에 따른 비교(Plastic tube/ Glass tube), 측정용기에 따른 비교(Plastic tube/Glass tube)를 하여, 세 가지가 결과에 미치는 영향을 알아보고자 한다. 성별 구분 없이 건강검진에서 정상 소견을 보인 성인 40명을 대상으로 실험하여 대조군과 세가지 다른 실험군의 Glucagon 결과를 비교하였다. Aprotinin첨가한 EDTA 용기에 채혈 후, 검체를 Glass tube에 3일 냉동 보관하여 Glass tube에서 실험(대조군)한 결과와 Aprotinin첨가하지 않은 EDTA 용기에 채혈한 결과(실험군1), Plastic tube에 3일 냉동 보관한 후의 결과(실험군2), Plastic tube에서 실험(실험군3)한 결과를 비교하였다. 통계적인 분석은 SPSS를 이용한 paired t-test와 단순선형회귀분석을 실시하였고 시약은 상품화된 Siemens사의 Glucagon RIA kit를 사용하였다. Aprotinin이 첨가된 EDTA 용기에 채혈하여 실험한 결과와 Aprotinin이 첨가되지 않은 EDTA용기에 채혈하여 실험한 상관계수는 r=0.783(p=0.064)를 보였다. 검체 분리 후 Plastic tube에서 3일 냉동 보관하여 실험한 결과는 Glass tube의 결과에 비해서 유의하게 낮게 나타났다(r=0.979, p=0.005). 또 측정 시 Plastic tube를 사용한 결과도 Glass tube에서 실험한 결과보다 유의하게 낮게 나타났다(r=0.754, p<0.001). Glucagon 검사 시에는 단백 분해효소 억제제인 Aprotinin이 첨가된 EDTA tube 사용이 권장되며, Plastic tube 사용 시 환자의 결과가 유의하게 낮게 나타나므로 검체는 분리 후 Glass tube에 냉동 보관하고 Glass tube에서 실험하여야 한다. Purpose: There are 3 warnings for Glucagon tests. First, EDTA tubes that already contain Aprotinin must be used for plasma collection. Second, for freezer storage of centrifuged plasma, glass tubes must be used. Last, glass tubes must be used for testing procedure. So we compared the glucagon results of next 3 situation to those of control group. First, We compared to results by tubes without Aprotinin and with aprotinin. Second, we compared to results by tubes(plastic vs glass) for plasma storage. Third, we compared to results by tubes(plastic vs glass) for testing. We tried to evaluate the results of the 3 different condition. Materials and Methods: 40 healthy adults were studied with normal results on the general medical check up and laboratory tests. We compared the results of 3 different condition belows: Blood were collected in EDTA tube containing aprotinin and plasma was stored in the glass tube for 3 days in a freezer and results were obtained by tests in the glass tubes. Results from EDTA plasma without aprotinin, results from platic tubes for freezer stroage, results from plastic tube when testing. Simple linear regression analysis and paired t-test using SPSS were done for statistical analysis. Commercial glucagon kit(RIA-method)which made by Siemens company were used. Results: Correlation coefficient between results of EDTA tubes with Aprotinin vs without Aprotinin was r=0.783 (p=0.064). Result of specimen in plastic tubes stored 3 days in a freezer showed lower value compared to those in glass tube(r=0.979, p=0.005). Also, results of testing in plastic tubes showed lower values than those testing in glass tubes. (r=0.754, p<0.001). Conclusion: It is recommended for glucagon determination to use EDTA tube with Aprotinin which is a inhibitor of protein breakdown enzyme. Results of plastic tube when storage and testing showed lower value than those of glass tubes, so it is recommended to store and test in glass tubes.
검체분리 및 보관온도 조건에 따른 Lactic acid의 농도 변화 고찰

We studied variation of concentration of Lactic acid in plasma that collected in a tube containing sodium fluoride(NaF) on temperature condition, specimen storage, separation. 30 specimen of healthy adult measured by the COBAS integra 800 from each cause that one is separated within 30 min another is not separated that Ohrs, 24hrs, 48hrs, 72hrs Lactic acid was increased even if specimen was separated from the cells about 10-11%. the point is that lactic acid should be measured immediately after separation from the cells.
Inhibin-A를 추가한 Quad Test의 한국인 산모의 임신주수별 Median치에 대한 평가
유자영 ( Ja Young Yoo ),최삼규 ( Sam Kyu Choi ),조영숙 ( Young Suk Cho ),황도영 ( Do Young Hwang ) 대한임상검사과학회 2005 대한임상검사과학회지(KJCLS) Vol.37 No.1
Human chorionic gonadotrophin (hCG) and unconjugated estriol (uE3) were added to AFP to make what is commonly known as the Triple test. The Triple test combines results from these three tests and has been a standard screening procedure for several years. Recent studies have demonstrated the usefulness of adding inhibin-A to Down``s syndrome risk assessment. The Quad test adds dimeric Inhibin-A (DIA) to the three other markers and uses the same computer program to calculate risk factors. Testing was performed between 14 and 21 weeks of gestation. Sample size were 648 samples and period of study was from 1, July, 2004 to 30, September, 2004. Used analytical methods for AFP, hCG and uE3 were radioimmunoassay (RIA) and dimeric inhibin A was enzyme-linked immunosorbent assay (ELISA). Adding dimeric inhibin-A as a fourth marker to the standard triple test increases the detection rate from 62 % to 75 % with a false-positive rate of 5%. The DIA based Quad test has been shown to be the most effective second trimester screening test for Down``s syndrome suitable for routine use. Increased DIA values are observed during normal pregnancy where a bimodal pattern response is seen. Values increase during the first trimester, decline after 14 weeks, and re-ascend between 17-25 weeks. Values for DIA may be additionally elevated during a Down``s syndrome pregnancy. Dimeric inhibin A is a glycoprotein hormone made by the ovary and placenta. DIA levels are twice as high in Down‘s syndrome pregnancies. AFP, hCG, and uE3 levels vary with gestational age, and incorrect gestational dating will influence results. DIA levels do not vary substantially with gestational age, resulting in greater screening accuracy. Although the Quad test is an improvement over the Triple test, it is important to underscore the fact that a positive test on both should be done. Most women who initially screen positive will be found to be carrying normal babies when amniocentesis and definitive diagnostic chromosome analysis are done.
