  • 목적: 본 연구에서는 분화갑상선암 환자에서 치료용량의 방사성옥소(I-131)를 섭취한 후 말초혈액 림프구에서 방사선적응반응이 유도되는지 알아보고자 하였다. 대상과 방법: 분화갑상선암에 대한 I-131 치료를 시행한 21명의 환자(남자 7명, 여자 14명, 평균연령 $55{\pm}12$세)를 대상으로 I-131 투여전과 5,550 GBq (150 mCi) 투여 후 72 시간에 각각 5 ml씩 채혈하여 배양하고, 배양 70 시간 후에 Cs-137 세포조사기를 사용하여 1 Gy의 감마선을 조사하였다. I-131 치료 후 채혈한 혈액 중 일부는 배양 68 시간째에 단백합성억제제인 cycloheximide (CHM) $10{\mu}g/ml$을 첨가하고 2시간 후에 2차례 세척한 다음 1 Gy의 감마선을 조사하였다. 대조군으로는 염색체 이상을 동반하는 유전병 병력이 없는 건강한 사람 10명(남자 6명, 여자 4명, 평균연령 $43{\pm}7$세)에서 분리한 림프구를 이용하였다. 환자군 중 I-131 치료 전에 채혈한 군과 I-131 치료 후 채혈한 군, 그리고 대조군을 각각 1 Gy를 조사하지 않은 군과 조사한 군으로 나누어 불안정 염색체를 계수한 다음 불안정염색체의 출현빈도를 나타내는 Ydr값을 구하여 서로 비교하였다. 결과: 대조군과 I-131 치료전 환자군에서 Ydr값은 $0.08{\pm}0.01$$0.09{\pm}0.01$로 유의한 차이가 없었으나, I-131 치료 후에는 환자군의 Ydr값이 $0.13{\pm}0.02$로 유의하게 증가하였다. 이 혈액에 1 Gy의 감마선을 조사하였더니 Ydr값이 대조군과 환자군의 림프구에서 1 Gy의 감마선을 조사하였더니 Ydr값이 대조군에서는 $0.24{\pm}0.01$이고, I-131 치료전 환자군에서는 $0.21{\pm}0.02$, 치료후 환자군에서는 $0.17{\pm}0.03$로 대조군에 비해 치료전 환자군에서 유의하게 낮았고, 치료후 환자군은 대조군과 치료전 환자군에 비해 더욱 낮았다. 증가치는 대조군 $0.16{\pm}0.01$, 치료전 환자군 $0.12{\pm}0.03$, 치료후 환자군 $0.03{\pm}0.02$로 치료후 환자군에서 유의하게 낮았다. 그러나, I-131 치료후 환자군에 CHM을 처치하고 1 Gy의 외부감마선을 조사한 경우에는 Ydr값이 $0.20{\pm}0.05$으로 CHM을 처치하지 않은 군에 비해 유의하게 높은 값을 보였다. 결론: 고선량의 I-131을 투여한 환자의 림프구에서 방사선적응반응이 유도됨을 알 수 있었고, 이 반응에는 단백질이 관여함을 알 수 있었다.

  • The effects of the addition of yeast on in vitro roughage degradability and methane production were investigated in order to clarify the effects of yeast on the rumen microbes and to establish methods of rumen manipulation. Three roughages (whole crop corn, rice straw and Italian ryegrass) were incubated for 3, 6, 12 and 24 h with or without dried beer yeast following the method described by Tilley and Terry. Using the same method, these roughages were incubated with or without yeast extract, albumin or purified DNA. In vitro methane production was measured with or without dried beer yeast at 12 and 24 h. The degradability of yeast was found to be 57 and 80% at 12 and 24 h, respectively. The rate of degradation of fraction b was 6.16%/h. There was a significant increase in roughage degradability at 6 h (p<0.05), 12 h (p<0.05) and 24 h (p<0.01) by dried yeast addition. The degradability of all three roughages was higher in the samples treated with yeast extract than in the no addition samples except in the case of rice straw incubated for 12 h. Nevertheless, the magnitude of increment was smaller with the addition of yeast extract than without the addition of yeast. With the addition of purified DNA, there were significant increases in roughage degradability at 6 h (p<0.01), 12 h (p<0.01) and 24 h (p<0.05); however, higher degradability values were detected in the samples to which albumin was added, particularly at 6 h. If the degradability values of the no addition samples with those of samples containing yeast, yeast extract, DNA and albumin were compared, the largest difference was found in the samples to which yeast was added, although it is worth noting that higher values were observed in the yeast extract samples than in the DNA or albumin samples, with the exception of the case of rice straw incubated for 24 h. Methane production was significantly increased at both 12 and 24 h incubation. The increment of roughage degradation and methane production brought about by the addition of dried beer yeast to the samples was thought to be due to the activation of rumen microbes. Water soluble fraction of yeast also seemed to play a role in ruminal microbe activation. The increment of degradability is thought to be partially due to the addition of crude protein or nucleic acid but it is expected that other factors play a greater role. And those factors may responsible for the different effects of individual yeast on ruminal microbes.

  • The distribution of airborne mercury was investigated from several districts of Seoul, five other major cities and two rural areas during the period April, 1994 to March, 1995. The method used in this study involves absorption of gaseous mercury on CHromosorb$^R$ A coated with gold and detection by cold vapor atomic absorption spectroscopy. The atmospheric mercury concentrations in Seoul ranged from N.D. to 120.17 ng m$^3$ (mean 27.01 $\pm 9.42 ng m^{-3}, N=139$), while those in rural areas ranged from 1.72 to 8.24 ng $m^{-3} (mean 4.57 \pm 3.07 ng m^{-3}, N=5$). The spatial distribution characteristics of mercury distribution in urban air were examined by comparing mercury levels as a function of the distance from the urban center. Temporal distribution trends of airborne mercury were also studied using the monthly mean mercury data of various districts in Seoul. The atmospheric mercury concentration around Mokdong wastes incinerator in Seoul were also investigated.

  • The gDNA isolated from Cyclina sinensis from Gochang (GOCHANG), Incheon (INCHEON) and a Chinese site (CHINESE), were amplified by PCR. Here, the seven oligonucleotide decamer primers (BION-66, BION-68, BION-72, BION-73, BION-74, BION-76, and BION-80) were used to generate the unique shared loci to each population and shared loci by the three cyclina clam populations. As regards multiple comparisons of average bandsharing value results, cyclina clam population from Chinese (0.763) exhibited higher bandsharing values than did clam from Incheon (0.681). In this study, the dendrogram obtained by the seven decamer primers indicates three genetic clusters: cluster 1 (GOCHANG 01~GOCHANG 07), cluster 2 (INCHEON 08~INCHEON 14), cluster 3 (CHINESE 15~CHINESE 21). The shortest genetic distance that displayed significant molecular differences was between individuals 15 and 17 from the Chinese cyclina clam (0.049), while the longest genetic distance among the twenty-one cyclina clams that displayed significant molecular differences was between individuals GOCHANG no. 03 and INCHEON no. 12 (0.575). Individuals of Incheon cyclina clam population was somewhat closely related to that of Chinese cyclina clam population. In conclusion, our PCR analysis revealed a significant genetic distance among the three cyclina clam populations.

  • This study was conducted to identify the soluble carbohydrates in soybean seeds using on-line HPLC-RID-ES/MS and HPLC behavior, and to deter­mine their contents for high quality soybean breeding. The monosaccharide (glucose) and three oligosaccharides (sucrose, raffinose, and stachyose) were identified in Korean soybeans by their chromatographic behavior and results of on-line HPLC-RID-MS with Electro­spray Ionization mode. On the basis of HPLC with a RID detector, the 32 Korean major soybeans contain $0.37{\pm}0.26\%$ glucose, $4.55{\pm}0.91\%$ sucrose, $1.19{\pm}0.19\%$ raffinose, and $2.72{\pm}0.37\%$ stachyose on a dry basis. In 468 soybean germplasms, the ranges of glucose, sucrose, raffinose, and stachyose were $0.03 - 0.98\%$, $2.33 - 6.96\%$, $0.08 -1.87\%$ and $0.75 - 3.18\%$, respectively. Among 500 soybean samples, oligosaccharide contents of 32 Korean major cultivated soybeans and 468 soybean germplasms were varied $5.83 - 10.06\%$ and $3.66 - 10.32\%$, respectively. The composition of glucose, sucrose, raffinose, and stachyose in soluble carbo­hydrates of 500 soybean samples were $2.07 {\pm} 1.75\%$, $58.01{\pm}5.82\%$, $10.13{\pm}2.28\%$ and $29.80{\pm}4.54\%$, respectively. Sucrose appeared to be most prevalent in soy­bean soluble carbohydrates.

  • Possibilities of predicting eggshell ultrastructure from direct non-destructive and destructive measurements were examined using 120 Fayoumi eggs collected from the flock at 45 weeks of age. The non-destructive measurements included weight, length and width of the egg. The destructive measurements were breaking strength and shell thickness. The eggshell ultrastructure traits involved the total thickness of eggshell layer, thickness of palisade layer, cone layer and total score. Prediction of total thickness of eggshell layer based on non-destructive measurements individually or simultaneously was not possible ($R^2=0.01$ to 0.16). The destructive measurements were far more accurate than the non-destructive in predicting total thickness of eggshell layer. Prediction based on breaking strength alone was more accurate ($R^2=0.85$) than that based on shell thickness alone ($R^2=0.72$). Adding shell thickness to breaking strength (the best predictor) increased the accuracy of prediction by 5%. The results obtained indicated that both non-destructive and destructive measurements were not useful in predicting the cone layer ($R^2$ not exceeded 18%). The maximum accuracy of prediction of total score ($R^2=0.48$) was obtained from prediction based on breaking strength alone. Combining shell thicknesses and breaking strength into one equation was no help in improving the accuracy of prediction.

  • In July 2008, The National Police Hospital has developed the CPOE system(Computerized Physician Order Entry system) which links the medicine master and introduced the new program for the injectable antimicrobial agents. After introducing new system, we wanted to check the management of oral antimicrobial agents. Because new system has limitation that new system control only the use of the injectable antimicrobial agents. So we tried to evaluate the use of oral levofloxacin, which was chosen by a medical specialist of the infection. We retrospectively analyzed the appropriateness of oral levofloxacin through EMR(Electric Medical Record) of 72 inpatients who received oral levofloxacin in National Police Hospital in December 2008. We applied the modified ASHP(American Society of Health- System Pharmacists) DUE(Drug Use Evaluation) criteria, which is composed of justification of drug use, critical indicators, complications and outcome measures. Acceptable cases of use of levofloxacin were 67(93.01%) and 57cases(79.2%) showed good outcome. However critical indicators were not performed very well. We want to suggest the new system for the management of the medical therapeutics by the pharmacist in charge.
