The volatile compounds of Myungtae (Alaska pollack) sikhae obtained by simultaneous steam distillation and extraction(SDE) apparatus were separated by gas chromatography(GC) and gas chromatography mass spectrometry(GC/MS). The totals of 155 volatile flavor components was identified in traditional Kyungsangdo Myungtae (Alaska pollack) sikhae, respectively. α-Zingihirene(11.03%) (E)-di-2-propenyl disulfide(7.95%) β-cironellol(6.02%), methyl allyl disulfide(3.58%), cryptone(3.39%), camphene(3.23%), pentano(3.21%), penadecanal(2.66%) and β-phellandrene(2.06%) were contained as the main compounds of Myungatae shikae. The fraction obtained from sikhae were tested for electron donating ability, angiotensin converting enzyme and xanthine oxidase inhibitory activity. There was no electron donation abilities(SC_50) of hexane and water fraction. On the other hand, the abilities of ethylacetate fraction and butanol fraction showed 310.64 ㎍.mL, 1096.49 ㎍/mL, respectively. Angiotensin converting enzyme inhibitory activities(IC_50) of ethylacetate fraction and butanol fraction were 1.623 mg/mL, 1.303 mg/mL, respectively. Xanthine oxidase inhibitory activities(IC_50) of ethylacetate fraction and butanol fraction were 3.591 mg/mL, 2.803 mg/mL, respectively.

최국선,김진영,이동희 연세대학교 대학원 1991 延世論叢 Vol.27 No.1

The production and characterization of Al-Cu alloy powders by the plasma- rotating-electrode process(PREP) was carried out to determine the influence of operating conditions(rotating speed, and plasma current) and alloy compositions on such particle characteristics as particle size distributon, shape, microstructure, and chemical composition. Each experimental condition showed a particle size range of 75∼353μm with mean sizes of 140∼160μm. The mean particle size of the powders changed with alloy compositions at the same rotating speed and plasma current. Particle shapes were mostly of the ligament type. Microstructures consisted mainly of dendrites, but also lamellar cell in the vicinity of eutectic composition. Al -20wt.% Cu powders of the same size, from even a single atomizing run, showed a wide variety of microstructure due to different thermal and nucleation history. Chemical compositions of alloy powders varied with particle size as a result of the interaction between high temperature plasma gas and material constituents of alloys during powder formation.

Backgrounds ; Study as to blood preservative solution is continuousely performed to prolong period of donor blood preservation which will cope with demand increase and autologous transfusion. In Korea, CPDA-1 solution, preserved 35 days, substituded ACD-B(21days), is currently used for anticoagulant preservative solution of blood. But SAG-M solution(42days) were widely used in other contries for longer preservation as RBCs additive solution. Authors compared the survival of RBCs preserved with ACD-B, CPDA-1 anticoagulant preservative solution, SAG-M RBCs additive solution to study changes of hematological and biochemical. Materials and Methods ; Blood were collected from 15 healthy male donors aged 22 to 23years, for three sorts of preservative solution bag made in home(Company Green Cross, Korea) at the same time. 5 of them were drawn into the blood bags containing ACD-B and another 5 into the CPDA-1 bags, the other 5 donors were collected into the blood bags with CPDA-1, plasma was removed by centrifugation serparation at 4,000rpm in 5minutes and replaced by 90 ml of SAG-M additive solution. All of blood bags were stored in blood bank refrigerator at 1 to 60℃. Samples were drawn at 1, 5, 10, 15, 20, 25, 30, 35 and 42days in each through blood bags tubing under sterile condition used SCD(Sterile Connection Device) so as to measure changes of hematological and biochemical. Results ; 1) A TP level is very important preservation index of hematological test. On 1 days, ATP levels of ACD-B anticoagulant preservative solution were measured by 4.85μmol/gHb, CPDA-1 5.05μmol/gHb, SAG-M additive solution 8.91μmol/gHb. After storage for 42days ATP levels ACD-B were measured by 1.54μmol/gHb, CPDA-11.72μmol/gHb, SAG-M 2.36μmol/gHb. 2) Plasma hemoglobin in bloods stored in ACD-B, CPDA-1 and SAG-M were 24.6mg/dl, 24.3mg/dl and 16.7mg /dl, respectively, on 1days, and increased to 221mg/dl, 154.5mg/dl and 146.4mg/dl, respectively, On 42 days. 3) Another hematological study cannot be seen remarkable discrimination between three sorts of preservative solution and preservation days. 4) pH, sodium, chloride and glucose level in bloods stored in ACD-B, CPDA-1 and SAG-M were slightly descresed according to storage days, whereas pottasium and phosphorus concentration increased according to storage days, However, there was no significant difference between bloods stored in three anticoagulants. Conculusion ; In 42 days, SAG-M RBCs additive solution is more excellent than other solution(ACD-B, CPDA-1 anticoagulant preservative sol) and has merit to separate plasma from the unit blood. Therefore we concluded that SAG-M RBCs additive solution should be used to overcome the state of b, SAG-M additive solution 8.91μmol/gHb. After storage for 42days ATP levels ACD-B were measured by 1.54μmol/gHb, CPDA-11.72μmol/gHb, SAG-M 2.36μmol/gHb. 2) plasma hemoglobin in bloods stored in ACD-B. CPDA-1 and SAG-M were24.6mg/dl, 24.3mg/dl and 16.7mg/dl, respectively, on 1 days, and increased to 221mg/dl, 154.5mg/dl and 146.4mg/dl, respectively, On 42 days. 3) Another hematological study cannot be seen remarkable discrimination between three sorts of preservative solution and preservation days. 4) pH, sodium, chloride and glucose level in bloods stored in ACD-B, CPDA-1 and SAG-M were slightly descresed according to storage days, whereas potasium and phosphorus concentration increased according to storage days, However, there was no significant difference between bloods stored in three anticoagulants. Conculusion ; In 42 days, SAG-M RBCs additive solution is more excellent than other solution(ACD-B, CPDA-1 anticoagulant preservative sol) and has merit to separate plasma from the unit blood. Therefore we concluded that SAG-M RBCs additive solution should be used to overcome the state of imported plasma in our country.

In this investigation the PFM(Pulse Frequency Modulation) will be used for optimizing PWM inverter pulse patterns. In traditional the pulse frequency of PWM is kept constant. But modulated PWM's frequency in this study, the sinusoidal inverter's performance should be improved. The PWM pulse patterns are definitely controlled so that the time-integral function of the voltage vectors in the space vector notation may show a circular locus. Further, performance index will be minimized because of minimizing distortion of output current. Finally, these theories are realized using single-chip microprocessor.

감마선분광분석 및 열형광선량측정법에 의한 자연환경방사선의 선량해석에 관한 연구를 1984년 10월부터 약 1년간에 걸쳐 충남대학교 대덕캠퍼스내의 1만㎡ 규모의 평면개활지에서 수행하였다. 이 연구에서 사용한 검출기는 3″ø×3″NaI(TI) 閃光計數器와 plastic에 밀봉하여 금속판에 압착 처리한 chip과 Teflon-disk 로된 2종의 LiF TLD였다. 실측실험으로는 3회에 걸친 24시간 cycle의 in-situ spectrometry와 2회의 3개월 cycle과 1회의 1개월 cycle에 걸친 TLD field dosimetry를 수행하였다. 측정한 모든 spectrum은 G(E)연산자법에 의하여 照射線量率로 환산하였고 그 결과로부터 환경방사선의 地殼成分을 산출하였다. 結果에 의하면 spectrometry로 구한 조사선량율이 평균(10.54±2.96)μR/hr, TLD chip으로 측정해석한 값은 (12.0±3.4)μR/hr, disk에서 얻은 값이 (11.0±3.6)μR/hr로 오차범위 안에서 매우 좋은 일치를 보이고 있다. 그러나 감마선분광분석에 의한 자연방사선의 日變化에는 가끔 심한동요가 관측되었다. 정확한 환경방사선량해석을 위하여 감마선분광분석과 TLD의 적절한 동시 배합사용이 바람직 하며, 보다 고감도의 TLD에 관한 연구와 국제비교등을 통한 선량평가의 精度向上을 위한 보다 깊이있는 연구가 필요하다는 結論에 도달하였다. A study for the assessment of natural environmental radiation exposure at a flat and open field of about 10,000㎡ in area in CNU Daeduk campus has been carried out by means of gamma-ray scintillation spectrometry and thermoluminescence dosimetry for one year period of time from October 1984. The detectors used were 3″ø×3″NaI(TI) and two different types of LiF TLD, namely, chip sealed in plastic sheet which tightly pressed on two open holes of a metal plate and Teflon disk. Three 24-hour cycles of in-situ spectrometry, and two 3-month and one 1-month cycles of field TL dosimetry were performed. All the spectra measured were converted into exposure rate by means of G(E) opertaion, and therefrom exposure rate due to terrestrial component of environmental radiation was figured out. Exposure rate determined by the spectrometry was, on average, (10.54±2.96)μR/hr, and the rates of (12.0±3.4)μR/hr and (11.0±3.6)μR/hr were obtained from chip and disk TLD, respectively. Fluctuations in diurnal variation of the exposure rate measured by the spectrometry were noticeable sometime even in a single cycle of 24 hours. It is concluded that appropriately combined use of TLD with iu-sitn gamma-ray spectrometry system can give more accurate and precise measure of environmental radiation exposure, and further study for more adequate and sensitive TLD for environmental dosimetry, including improvement and elevation of accuracy in data assessment through inter-laboratory or international intercomparison is necessary.

The present studies were undertaken to evaluate the effect of vitamin E, CCl_4 on the change of hepatic triglyceride, hepatic cholesterol, hepatic phospholipid in male rat. The result obtained from this study were summarised as follows: 1. Hepatic phospholipid of CCl_4 treated rat was increased in proportion to CCl_4 dosage but after concomitant injection(I.P) of vitamin E and CCl_4, hepatic phospholipid was significantly decreased in comparison to that of CCl_4 alone injection. 2. There was no effect on hepatic cholesterol concentration either CCl_4 alone injection(I.P) or concomitant injecton(I.P) of vitamin E and CCl_4. 3. Hepatic triglyceride of CCl_4-treated rat was significantly increased in comparison to that of normal rat but hepatic triglyceride of rat concomitant injection of vitamin E and CCl_4 was significantly decreased in comparison to that of CCl_4 alone injection.
