Although the Working Formulation is commonly used to classify NHL in Korea, it has been recognized as imperfect for primary extranodal lymphoma, expecially for patients with nasal, paranasal disease because of their histological characteristics. Angiocentric T/NK cell lymphoma remains rare clinical presentation in North America and Europe but is more common in Asia and Latin America. The optimal mode of treatment has also not been decided on, probably because of their rarity and limited understanding of its natural course. The aim of this study was to analyze our experience with 14 patients with angiocentric lymphoma seen at the Chungnam Natioanl University Hospital over the last 5 years. We reviewed the records of 14 patients who were treated at the Chungnam National University Hospital between January, 1996 and December, 2000. The angiocentric T/NK cell lymphoma accounted for about 8.2% of NHL. The median age was 52.5 (range 36-71) years. Sex ratio was equal. According to the Ann Arbor staging system, disease was classified as stage Ⅰin 3 patients, stage Ⅱ in 8 patients and stage Ⅳ in 3 patients. Systemic B symptoms were present in only four patients in only four patients. All patients has extranodal involvement. The most frequently involved extranodal sites were nasal cavity followed by paranasal sinuses and orpharynx. The most common presenting symptoms were nasal obstruction with purupent rhinorrhea followed by dysphagia. According to the International prognostic index (IPI), most patients was in low-risk group (11 patients). Nine patients responded completely. Seven patients were received combination chemotherapy and 2 patients had radiation therapy as a initial treatment. Five patients were relapsed. After a median follow-up of 660.5 days, the overall survival and disease-free survival rates at 3 years was 56.8% and 42.9% respectively. The median survival time was not yet reached. The median overall survival time was 1338.5 (range 1212-1564) days for non-relapsed and 733.4 (range 302-1008) days for relapsed patients. The median time from CR to relapse was 100.5 (range, 39-159) days. There were limitations to know enough about the characteristics of angiocentric T/NK cell lymphoma because of a small number of patients. In the future, multicenter trials will be neccesary to identify clinical characteristics, optimal treatment mordalities and their responses, and prognostic factors.

The differences of the liver scintigraphic features between postnecrotic and nonpostnecrotic liver cirrhosis were studied for 69 patients. Degrees of mottling and splenomegaly were no different between two groups but shrinked form was more frequent finding in postnecrotic type(23:10), and normal shape & enlarged left lobe with shrinked right lobe were relatively dominant in non-postnecrotic group(15:6, 10:2). Grade of extrahepatic uptake of ^99mTc-tin colloid was significantly higher in Child-Pugh B & C group than A group(p<0.05), but there was no difference between postnecrotic and non-postnecrotic groups. These will be important results on the dicision for the presence of cirrhosis according to the variable causes.

During the last two'decades the nation has experienced a drastic change of the nation-wide spatial features. The economic expansion of the industrial bases in general and the dynamic growth of manufacturing in particular have persisted in the process of a series of economic development schemes, along with the physical land plans, resulting in the phenomenal transformation in the existing spatial framework of the nation. Especially, the construction of the national expressway networks was a propellent for changes in the various facets of the environment, physical and socio-cultural. Even though the highway network, together with facility of communication system, has helped to speed up the flow of the man and goods among region, it has been also as factor for the regional development in the typical rural hinterland. It is assumed that once a new highway is built up, the people in nearby area affected by the barrier of physical environment will receive many facets of environmental impacts in daily life. One of its positive side-effects is the increase of opportunities in terms of social and economic activities, because people, set free from the physical barrier, are provided with the easy access for information and movement. This paper is primarily concerned with the finding of the perceived behavioral modes in a typical from communities in relation to the utilization of the central places; it is also aimed at providing some useful information of socio-economic status in the physically isolated rural area by which a new highway under near completion will be passed. Geochang-gun(郡) was selected for the case study. Tweleve sruvey units, of which one unit consisits of 18 subitems, were selected to obtain the broad scales of socio-economic data through interview with residents to see how activity or perceived activity is related to the basic socio-economic structure and how people respond to their needs of certain services such as education, shopping movement of residents, choice of place for jobs. Some characteristics found out through the analysis can be as follows. First, Geochang-gun belongs to an isolated rural society with dominant mode of farming activity in which the traditional value of life is prevalent but the changes in the socio-economic environment loom through diffusion of innovation. Second, it seems that most farming communities have faced the trend of population decrease due to outmigration toward urban areas while Geochang-eup(邑), a central place town, has shown the opposite effect for its strong tertiary industrial activities. Third, it is identified that Geochang-eup has played more important central place functions relative to its comparable counterparts in the size of population because of lack of compective towns or cities at the perimeter of the 50km radius. Fourth, in relation to the perceived level of familiarity for neighbor cities, people seem to be biased toward such factors as distance from cities, functions respective city provides, centrality of each and presence of kinfolks and friends. Perceived levels for neighbor cities appeared in the order of Daegu, Busan, Seoul and Junju. Fifth, as regard the perception for resident movement, it seems that people are directly influenced by personal motive personal experience as to the purpose of movement, the time-interval for residence, the nature of movable place and distance. The preferred place for seeking jobs wes choiced in the order of Busan, Daegu, Seoul, Geochang-eup and Jinju whereas the desirable place for the higher education appeared in the order of Daegu, Seoul and Jinju. Sixth, according to the analysis of utility of central place facilities based on 4 class of 15 items, most people have been relied on Geochang-eup Daegu city for meeting their needs for services. Daegu shows more acceptance in the highest order functions in the hierarchy, while Geochang-eup receives a broad scale of preference in the upper three order functions and village centers dominate the fourth order function. Seventh, it is identified that the social status of the local residents reflects the differences in th preference of the central place. As a result of this basic analysis, it is felt that the present paper serves a useful but limited purpose by drawing attention to the behavioral aspects of social environment which need to be through investigated in the follow-up research in the near future.

熱帶豆科作物 Winged Bean (Psophocarpus tetragonolobus(L.) DC.)의 定植期와 收量

李龍三,尹晟鐸 濟州大學校 亞熱帶農業硏究所 1989 亞熱帶農業硏究 Vol.6 No.-

本 試驗은 TPT-8, UPS-63을 공시하여 定植時期에 따른 winged bean의 種實收量과 green pod 收量 그리고 이들의 수량구성요소를 조사하여 적정 정식기를 구명코자 시험하였던 바 그 결과를 요약하면 다음과 같다. 1. 種實收穫區 및 green pod 收穫區 모두 開花所要日數는 정식일이 늦을수록 단축되는 경향이었으나 開花期는 거의 비슷하여 長日性植物로 판단되었다. 2. 定植期間 種實收量을 보면 5월 30일 定植期가 가장 수량이 많았으며 같은 정식기의 UPS-63이 185kg/10a로 가장 수량이 많았다. 3. 定植期間 green pod 收量은 5월 30일 定植期가 가장 수량이 많았으며 가장 수량이 많았던 구는 5월 30일 정식구의 TPT-8로 1834.3kg/10a이었다. Two varieties, TPT-8 and UPS-63 with three transplanting date of May 1, May 15 and May 30 were tested to determine optimum transplanting date of winged bean (Psophocarpus tetragonolobus (L.) DC.) in relation to seed yield and green pod yield. The results obtained are summarized as follows; 1. Days from planting to flowering were shorter as transplanting date got later in both seed harvest trial and green pod harvest trial. But flowering date was about the same time, indicating that winged bean is long-day plant. 2. Among transplanting dates, May 30 transplanting date yielded the highest seed yield and UPS-63 in the same transplanting date showed the highest seed yield by 185.0kg/10a. 3. Among transplanting date, May 30 transplanting date also yielded the highest green pod yield and TPT-8 in the same transplanting date obtained the highest yield by 1,834.3kg/10a.

Endotoxin crystals produced by B.thuringiensis var. darmstadiensis cultured in modified GYS medium over 72 h were ovoidal in shape and separated using Renografin gradient centrifugation. The crystal protein bands were observed. When B.thuringiensis var sotto was grown in the modified GYS broth, it entered stationary phase at 8-9 h after inoculation. Proteinaceous crystals were banded at the position in 40% of Renografin gradient. The solubilized crystal proteins were formed by two bands, 130 Kd and 68 Kd in the SDS-PAGE. One plasmid was observed in B.thuringiensis var darmstadiensis and no plasmid in var. sotto in this study. Enzyme activity of amylase produced B.thuringiensis var kurstaki strain in the basal medium was 0.4 units per ml, and was enhanced to 0.6 units per ml in the basal medium contained soluble starch, Ca^++, Mg^++ and Mn^++ ions. Amylase production medium containing soluble starch was suitable for the amylase production and the highest activity appeared at 4-6 h after cultivation at 32℃. The amylase activity obtained by ethanol precipitation was 0.20 units per ml in 0.1 M phosphate buffer. The band of the molecular weight of 50 Kd was observed by SDS-PAGE analysis. Km value of the amylase for the soluble starch was 6.80 mg per ml.
