郭鍾瀅,鄭鉉丞 진주산업대학교 1968 論文集 Vol.1 No.-

育成豚 飼料로서의 Russian Comfrey의 利用價値를 究明하고자 各各 4頭의 育成豚에 Russian Comfrey를 10%·20%· 30%씩 代置한 飼料와 基本飼料를 給與하여 比較飼養한 結果 다음과 같은 成績을 얻었다. 1)豚의 增體量은 10%代置區가 가장 優秀하였고, 30%代置區가 가장 不良하였으며, 20%代置區는 對照區와 有意差가 없었다. 2)飼料利用性도 對照區에 比하여, 10% 代置區는 優秀하였으며, 20%代置區는 비슷하고, 30%代置區는 不良하였다. 3)Russian Comfrey를 10%∼20% 程度로 代置飼養하면 飼料費가 節約되었으며, 30%代置는 不利하였다. 4)Russian Comfrey에 對한 豚의 嗜好性은 比較的 良好하였으며, Russian Comfrey 30%까지 代置給與하여도 健康上 異常은 별로 없었다. 以上의 結果로 보아 Russian Comfrey를 養豚飼料로 10%∼20% 程度 代置함으로써 有利한 經營을 꾀할 수 있다고 생각된다. The experiment was conducted to determine the feeding value of Russian Comfrey (Symphytum peregreoium) for pigs. Sixteen berkshire gilts were alloted into 4 treatments according to the levels of Russian Comfrey (R.C.) such as 0%, 10%, 20%, and 30% (on air-dried basis) in pig ration. Body weight gain, feed efficiency, economical feeding value and palatability in each treatment were investigated. The experimental results obtained were as follows: 1)In weight gain, the pigs fed 10% R.C. ration showed more gain (P<0.05), but those fed 30% R.C. ration showed less gain (p<0.05) than control group of pigs did. And the pigs fed 20% R.C. ration showed no more gain than the control pigs statistically. 2)Feed efficiency in 10% R.C. ration was also higher than that in any other rations. 3)Feed cost for 1kg. weight gain was lowest in 10% R.C. ration and slightly higher in 30% R.C. ration than that in control ration. 4)From the feed intake it was considered that Russian Comfrey should be considerably palatable to pigs. And from the above results, it was estimated that Russian Comfrey could be supplemented by 20% in the pig ration successfully.

The authors present two cases of solitary thalamic abscess which were intially diagnosed as malignant thalamic glioma. After treatment with steroids and osmotic agents, the patients' clinical conditions improved after two to three days. However, sudden deterioration of consciousness level developed and the CT scan showed acute hydrocephalus with increment of thalamic low-density lesions. We performed extraventricular drainage and obtained CSF containing numerous inflammatory cells. This suggested the possibility that the lesion was a pyogenic abscess. which progressed to ventriculitis, rather than a malignant glioma. Stereotactic aspiration of the lesion confirmed thalamic abscess. These findings and review of previous reports of thalamic abscess suggested that early diagnosis and stereotactic drainage of the thalamic abscess is of primary importance.

Background and aims: The Apolipoprotein E is a ligand of both the protein component LDL receptor as well as the apo E LDL-Receptor related protein (LRP). It modulates the receptor binding of lipoproteins, with the apolipoprotein E found on cell surfaces as its component, thus serving an important role in the lipid metabolism by carrying out the intracellular transport of cholesterol in lipoproteins. The gene for apolipoprotein E is the product of three common genotypes as well as many more rare alleles. The common genotypes are ε2, ε3, and ε4, and are expressed in the three phenotype isoforms of E2, E3, and E4. In the event that E4 is the main component, a rise in the cholesterol level, as the result of down-regulation of the LDL receptor, is observed. Therefore, those samples with E4 genotypes are known to be in much higher risk of coronary artery disease than those with ε3/ε3, while those with ε2 are in low risk (with the exception of hypertiglyceremai Ⅲ). The aim of this study is to analyze in patients with ischemic heart disease the role of aplipoprotein E alleles in order to seek its correlation with coronary artery disease, as well as to seek whether the polymorphism of apo E produces any differences in the severity of coronary artery disease according to plasma lipid levels. Methods: The subjects for study were 273 patients admitted to the Internal Cardiology Division of the Soonchunhyang University Hospital form December 1998 to February 1999. The subjects were divided into the two groups of which one was ischemic heart disease (IHD) experiment group totaling 105 (avg.60.1 years of age, male/female ratio = 69/36) and the control group totaling 168 (avg. 59.7 years of age, male/female = 73:95). The coronary angiogram was given to 127 subjects, and of this total, 94 have developed significant stenosis in the coronary artery. The stages of the analyzing of the apo E phenotype was first, the separation of DNA from the blood samples, subjecting it to the PCR from with 228 base pairs of expanded products were obtained. The band was determined by means of the reverse hybridization principle on the nitrocellulose strip. Results: From the 105 patients the distributions of apo E phenotypes were as follows: ε3/2(5.7%), ε4/2(1.9%), ε3/3(70%), ε4/3(20%), ε4/4(1.9%). The relative frequencies of each allele are as follow: ε2 (0.038), ε3 (0.833), ε4 (0.128). The results show as follows: ⅰ) The IHD experiment group to have a higher occurrence of ε4/3 phenotypes as well as ε4 alleles than the control group. ⅱ) Both the control group and IHD group showed the largest distribution of ε3/3 for phenotypes, and ε4 for alleles. ⅲ) The IHD group showed less ε2/3 phenotypes as well as significantly less allele frequency of ε3 in comparison to the control group. ⅳ) the IHD group showed a much lower level of HDL in comparison to the control group, while the LDL was significantly higher; samples including the apo ε2 showed a significantly higher level of HDL than those without. Among the control group, samples including apo ε2 showed a significantly higher level of TG (triglyceride) than samples without. No significant difference was found between the experiment apo ε4 sample and the control plasma lipid sample. ⅴ) No significant correlation was found between an apo E polynorphism and the number of involved arteries of a coronary angiogram. Conclusion: Between the experiment IHD group and control group were found differences in the frequency of alleles. The polymorphism of apo E alleles may contribute as a risk factor to the development of heart disease by involving itself in the metabolism and modulation of plasma lipids.

To acquire an industrially useful biocatalyst for the enzymatic synthesis and production of various D-amino acids, 1,300 thermophiles isolated from the soil of Korea were analyzed for D-amino acid aminotransferase (D-AAT) activity. The enzyme activity was found from 110 strains of isolated thermophiles revealing its wide occurrence in thermophiles. Enzyme activity and thermal stability of the D-AAT producers were compared. Finally we have selected four thermophiles as producers of potent biocatalysts for the D-amino acid production; two therrnophiles, Bacillus sp. LK-I and LK-2, having higher specific activity and two thermophiles, B. stearothermophilus KL-01 and Bacillus sp. KLS-0l, having higher thermal stability than the D-AAT producers. Taxonomic and physiological characteristics of the four isolated thermophiles were described herein.

This experiment was conducted to study the effects of level of dietary energy and protein on the growth rate, feed intake and feed conversion of chicken. One hundred and eight male baby chicken of Leghorn was used for 56 days. Starter ration (CP-17, 20,23%; M.E-1,030, 1,200, 1,370㎉/Lb) was fed to chicken for 4 weeks from 3 to 6-week age, and finisher ration (CP-14, 17, 20%; M.E-1,000, 1,215, 1,430㎉/Lb) was fed to chicken for 4 weeks from 7 to 10-weeks age. The results obtained from this study may be summarized as follows; 1) As the level of energy or protein increased in the ration, average daily gain were increased significantly. 2) Amount of feed consumed was significantly higher as the level of dietary protein. In feed conversion, chickens fed higher protein or higher energy were much superior to the chickens fed 10 wer protein or lower energy. 3) There was no influence of dietary energy or protein level on the chicken mortality. 4) Feed cost per kilogram of full body weight gain was increased greatly as the dietary energy level increased. 5) From the above mentioned results of this experiment it was thought that C_1 was profitable level in this study.

김상범,신기석,박은석,곽윤철,천한진,함현식 한국화학공학회 2003 Korean Chemical Engineering Research(HWAHAK KONGHA Vol.41 No.1

메탄의 부분산화에 의하여 힙성가스를 제조하였다. 촉매는 니켈 담지 촉매를 사용하였으며, 담지된 니켈의 양은 10-15 wt%이었다. 담체로는 BaO, CaO, MgO를 사용하였다. 촉매는 함침법으로 제조하였으며, 반응은 CH_4:O_2의 비가 2:1, 1 atm, 750℃에서 수행하였다. 반응결과, MgO를 담체로 사용하였을때 가장 좋은 촉매활성을 보여주었으며, 니켈의 담지량이 13 wt%일때 촉매의 활성이 가장 좋았다. 이 13 wt% Ni/MgO 촉매의 경우 80%의 메탄 전화율과 93% 및 94%의 CO 및 H_2 선택도를 각각 얻을 수 있었다. 또한 이 촘매는 약 180시간 정도의 반응 후에도 촉매의 활성이 감소하지 않았다. 논란 중인 반을 기구에 대하여 조사해 보기 위하여 펄스방식으로 반응물을 투입하며 촉매 상 · 하층의 온도를 측정하였고, 반응시간에 따른 반응물과 생성물의 몰수 변화, 그리고 O_2-TPD 실험을 수행하였다. 그 결과 메탄으로부터 합성가스가 생성되는 경로는 2단계반응으로써 메탄이 완전 산화되어 CO_2와 H_2O가 생성되고, 이 생성된 CO_2 및 H_2O가 미반응 메탄과 각각 개질반응을 하여 합성가스가 생성됨을 알 수 있었다. Synthesis gas producution by partial oxidation of methane has been investigated using BaO, CaO and MgO supported Ni catalysts. The catalysts were prepared by the impregnation method. The reaction was carried out at I atm, 750℃, and CH_4:O_2=2:1. The highest catalytic activity was obtained with MgO support when Ni loading was 13 wt%. With the 13 wt% Ni/MgO catalyst, methane conversion was 80%, and CO and H_2 selectivities were 93% and 94%, respectively. The activity of the catalyst remained nearly constant after 180h of the reaction. To investigate the reaction mechanism of this reaction, the temperature of the actalyst bed at top and products were determined with time; and O_2-TPD experiment was carried out. From the results, it is deduced that the reaction takes place by a two-step reaction-first, total oxidation of methane to CO_2 and H_2O takes place, and then the produced CO_2 and H_2O are further reacted with CH_4 to give synthesis gas.
