Lipomas are common soft tissue tumors that are located in the body tissues containing adipose tissues. However, lipomas arising from the walls of a vein are very rare. Intravascular lipomas have been described most commonly in association with the inferior vena cava. Intravascualar lipomas involving the subclavian vein are rare. We are reporting a case of an asymptomatic lipoma of the right subclavian vein, growing into the right brachiocephalic vein.

The major flavor compounds of Takju mash which was brewed with a modified Nuruk made by inocu-lation and cultivation of Rhizopus japonicus T2, Aspergillus oryzae L2 and Hansenula sp. BC26 isolated from Nuruk, were analyzed, as compared with those with current fermenting agents such as commerical Nur-uk and rice koji of Aspergillus kawachii. The contents of isoamyl alcohol isobutyl alcohol and ethyl acet-ate which were known as aroma compounds in Takju were much higher in mash of modified Nuruk than in that of commercial Nuruk or ricd koji. The major organic acids were lactic fumalic and succinic acid in mash of modified and lactic and acetic acid in mash of commercial Nuruk and citric lactic and suc-cinic acid in mash of rice koji. The contents of total organic acids were 5,146mg/L, 1,706mg/L and 1, 388 mg/L in mash of commercial Nuruk rice koji and modified Nuruk respectively. The major free amino acids were glutamic acid alanine proline and histidine in mash of modified Nuruk and glutamic acid proline leucine and histidine in mash of commercial Nuruk and arginine proline and glutamic acid in mash of rice koji. The contents of total free amino acids were 14,090mg/L 12,202mg/L and 7,152 mg/L in mash of modified Nuruk commercial Nurcuk and rice koji respectively. Therefore it seemed that the Takju mash of modified Nuruk was better than that of commercial Nuruk or rice koji.

It may be said that ancient wild Chinese garden had been founded during Qin dynasty and completed through Han, Sui and Tang dynasties. At first used as hunting areas for kings, the ancient resort forests began to take forms of garden. They dug a pond in the garden and made a simulated mountains with the soil that came from the excavations for the pond and suc pavilions has Gyong, Ru, Gak etc. were built around the pond. The ponds were different in size from those in Korea, being of the lake-like size. they made three island in the pond, which were the islands of Taoist hermits with supernatural powers, called Bong-lae, Young-ju and Band-jang respectively. the traditional of making those islands began in the Qin era and were completed in the Han era, being descended to posterity as a traditional garden structure of 'three islands in one pond' garden style. Such style was brought to Korea and first appeared as Kung-Nam-Ji in Back-jae kingdom and then brought to Japan, becoming the tradition of constructing ponds from early Heian era. Those lake-like huge Chinese ponds constituted the core of ancient garden where various feasts took place. Such ponds were also placed at the center of the gardens and played the roles of feasting garden ponds. Through the above-mentioned studies of the ancient Chines garden, the origin of them and the influence of the ancient Chinese ponded garden upon those of Korea and Japan were investigated.

본 연구는 Streptomyces sp. BH-405의 배양액으로부터 유기용매로 추출하여 지질과 산화에 대한 항산화 효과를 실험하였다. Streptomyces sp. BH-405의 배양액을 ethylether로 추출한 후 silica gel column(100$\times$10 cm) chromatography로 분획한 획분을 POV로 측정한 결과 fraction 3에서 향산화 활성이 가장 높았다. 항산화 활성이 높은 fraction 3 획분을 다시 preparative TLC와 column chromatography로 더욱 정제하여 band 2를 얻었다. Band 2의 항산화 효과를 알아보기 위해 기존의 항산화제와 비교한 결과 이-$\alpha$-tocopherol, BHA보다 산화억제 효과가 높았으며 DPPH에 의한 수소 공여능은 실험결과가 우수하였다. 한편 band 2는 쥐 간의 microsome에 있어서 유리기의 소거기능이 있었고 NADPH 및 Fenton 시액에 위한 효소적 과산화 지질의 생성을 억제하였다. 그리고 mitochondria와 리놀산의 과산화 유도계에서도 지질의 과산화 과정에 생성하는 유리기의 형성을 차단하였다. 결론적으로 Streptomyces sp. BH-405의 배양액에서 얻은 획분인 band 2는 산화를 억제하는 활성이 있었다.

A clinical investigation was reported on 17 cases of spontaneous pneumothorax requiring surgical mana-gement. Males outnumbered females 15:2. Determination of the etiology in this series showed that the majority were pulmonary tuberculosis and paragonimiasis. Several others had pneumonia, lung abscess, cyst and blebs. It is of particular interest that the acute inflammation of respiratory system was younger age group, pulmonary tuberculosis & paragonimiasis were between 2 nd and 3 rd decades, and lung abscess, cyst, blebs were above 4 th decade. Pulmonary tuberculosis was far advanced bilateral and active. The ratio of right to left side was 13:6 and both side involved in 2 cases. In about half cases of patients, above 50%-collapsed lung associated with mediastinal shifting developed. The complications were pleural effusion and bronchopleural fistula. The former was 13 cases [76.4%] in which 3 cases combined with mixed infection, and latter was 5 cases. As the management, 11 cases were subjected to intercostal or rib resection drainage with continuous suc-tion. Among 11 drainage cases, 8 cases were successful in acute stage and 3 cases failed in chronic stage. This faiure was due to interference with re-expansion of collapsed lung for peel formation and broncho-pleural fistula. The open thoractomy was applied in 9 cases, among which primary operation were 5 cases and drainage failure were 4 cases. Among 11 cases subjected to the open thoracotomy, wedged resection was performed in 3 cases including paragonimiatic cyst, and pneumonectomy in 1 case-tuberculosis, and decortication only was performed in 2 cases in paragonimiasis. Decortication & lung resection was carried out in 2 patients among which ruptured lung abscess 1 case and ruptured multiple blebs 1 case. There was no case of death but prognosis of the tuberculosis may be poor because of far advanced bilateral and active pulmonary tuberculosis.

본 연구의 목적은 터어빈 회전차를 모델로한 복합회전형 히이트파이프의 전열특성을 실험과 유한요소의 해석법에 의하여 연구한 것이다. 입열량과 회전수에 따른 Nu, Re, Pr 그리고 무차원 응축액막두께가 변수로 사용되었다. 해석과 실험치는 거의 유사한 경향으로 일치하였으며, 연구결과는 복합히이트파이프 성능예측을 하는데 도움을 주었다. 복합회전형 히이트파이프에서의 열저항은 응축액막두께가 감소함에 따라 응축부의 열전달은 급격히 증가하였고, 응축액막두께는 복합회전형 히이트파이프의 전열 특성에 가장 큰 영향을 주었다. 주어진 Pr에서 Re가 변화함에 따라 무차원 응축액막두께가 일정한값으로 나타났고,무차원 응축액막두께는 회전수의 역수의 제곱근에 비례하였다. 본 연구의 해석적 방법에 의해서 Nu=A$({\delta}({\omega}/v)^{-1/2}Re^B)$라는 식을 구했고, 이때 A=0.963, B=0.5025의 값을 얻었다.

$Fragaria{\times}ananassa$, a strawberry evolved from hybridization between F. virginiana and F. chiloensis, is a globally cultivated and consumed fruit crop valued for its flavor and nutritional value. Flavor and quality of fruits are determined by factors such as sugars and organic acids present during fruit development. These characteristics are highly subjective in different genotypes and affected by various environmental factors. In this study, we analyzed contents of major sugar compounds including fructose, glucose and sucrose by HPLC analysis in four cultivars namely, Maehyang, Seolhyang, Festival and Sweet Charlie. We identified 55 genes related to fructose, glucose, sucrose and soluble sugar regulation whose expression were analyzed in four cultivars at three developmental stages of the fruit namely, green, white and ripened stages. Expression of these genes across these progressive fruit developmental stages varied among cultivars. Among the 55 genes, genes FaFru3, FaSuc11 and FaGlu8 revealed differential patterns of expression along developmental stages of the fruit in high and low sugar-containing genotypes, respectively and may be putative candidates for sugar content in strawberries. Expression of genes are discussed with regard to corresponding sugar content in these genotypes. Further analysis and application of these genes may be valuable in developing high sugar containing cultivars via marker-assisted breeding.

Zymomonas mobilis 유래 levansucrase 유전자(levU)를 GAL1 promoter 하류에 연결시킨 pYES-levU와 GAL10 promoter 하류에 Kluyveromyces marxianus exoinulinase의 분비 신호서열(INU1 ss) 하류에 연결시킨 pYInu-levU를 각각 구축하였다. 이들 plasmid를 invertase 결손 변이주(suc2-$\Delta$9)인 S. cerevisiae SEY2102에 형질전환시켜 고활성 형질전환주를 선발하였다. 효모 형질전환주를 galactose 함유 배지로 배양한 결과, pYES-levU 함유 형질전환주인 경우 levansucrase의 총활성은 7.17U/ml이고, pYInu-levU 함유 형질전환주인 경우 6.61U/ml에 도달하였다. 발현된 levansucrase 약 50% 정도가 배지와 periplasmic space에 존재하였고, INU1 ss에 의한 분비효율 증가는 관찰할 수 없었다. 또한, 효모에서 발현된 재조합 levansucrase는 과당쇄화된 형으로 생산되는 것으로 보여진다.

The optimum extraction conditions of green tea used for a bath were investigated for application to textiles. The stability of the extracts and content of active ingredients were analyzed as well. The extraction was more effective in water and methanol than in ethanol. The optimum extraction temperature was determined as $80^{\circ}C$ in water and $60^{\circ}C$ in methanol. The solid extracts were obtained about 7% in water and 9% in methanol on the weight of dry green tea. The extracts were more stable in acid and neutral conditions than in alkaline region. From the analysis of contents of active ingredients, about 20% of effective catechins was appeared to be contained in the extract solid, which was thought to be available for application to textiles.
