Castleman' s disease is a rare, reactive lymphoid proliferation of unknown cause and pathogenesis. Depending on histololgic findings, it has been divided into two distinct histologic subtypes that include hyaline-vascular type(90%) and plasmacell type(10%). This disease occurs most commonly in mediastinal lymph nodes and cervical lymph nodes, inguinal lymph nodes respectively. But occurs rarely in retroperitoneum. We report a case of hyaline-vascular type asymptomatic Castleman' s disease of the retroperitoneum in a 47-year-old man.

Background: Nitric oxide(NO) is known to have protective effects on an ischemic heart and to exert triggering effects on ischemic preconditioning. However, the effects of NO during the ischemic period have not been investigated. To investigate the role of exogenous nitric oxide in a model of ischemic heart cell death, we studied the effects of ischemic preconditioning and ischemia in a normal and an ischemic buffer. Methods: Rat cardiac myoblast cells(H9c2) were cultured in a normal and an ischemic buffered medium. For the ischemic culture of heart cells, the cells were cultured in a dessicator with GasPak for 5 hrs. In ischemic preconditioning, the cells were pretreated with ischemic buffer for 5 min and then perfused with normal medium for 30 min. For the measurement of the cytotoxicity, a MTT(3-4-Sdimethylthiazol-2-yl-2,5-diphenyl tetrazolium bromide) assay was performed. A DAPI(4',6-diamidino-2-phenylindole dihydrochloride) staining procedure and a flow cytometry analysis were performed to confirm apoptotic cell death by ischemia. Results: Cell viability, as determined by using a MTT assay, showed that the preconditioned group treated with NO showed more cell death than with the not-preconditioned groups in both normal and ischemic buffers. But, In normal medium and not-preconditioned groups, NO showed protective effect according to the concentrations(100,1000μM) . No treatment with NO produced the different results. In normal medium, the protective effect of ischemic preconditioning was demonstrated, but no protective effect of ischemic preconditioning could be seen in the case of the ischemic buffer. The DAPI staining and flow cytometry analysis of heart cells showed characteristic apoptotic features. Conclusion: NO added in the ischemic phase had deterious effects on heart cells. Ischemic preconditioning was more harmful than ischemia alone. The toxicity of the cells was characteristic apoptosis.

The purpose of this research was to examine the interrelations among learner-related variables(IQ, academic self-concept : Asc, school-related adjustment : Sad and academic achievement : Aa) (LRV), the mutual differences by levels of LRV and the effect of LRV on each variables. This research were investigated through the following problems. 1) What significant interrelation coefficients are there among learner-related variables(LRV : IQ, Asc, Sad, Aa)? 2) What significant differences are there between high and low level of LRV respectively and each learner's variables? 3) What the combined and relative effects are there LRV and LRV's subfactors on each variables? The subjects for this research were 627(M : 333, F : 294) and selected randomly from secondary school(Middle : 293, High : 334) in Seoul area. And instruments used for this research were 'Self-concept scale'(Kim, Y. R., & Koo, S. S., 1989), 'School-related adjustment scale'(Kim, Y. R., & Koo, S. S., 1991), 'Teacher-made test' and various kinds of 'Standardization intelligence test'. The collected data were processed simple correlation, differences and regression analysis through SPSS program. The major findings of this research were as follows : 1) The correlation coefficients between learner-related variables(IQ, Asc, Sad and Aa) and one variable among learner-related variables(LRV) were statistically significant positives as the range of .1885(IQ and Sad)~.6699(Asc and Sad)(p<.01) respectively, and especially the correlation Asc and Sad was the highest(r=.6699, p<.01). And the correlations IQ and Asc's sub-factors were statistically significant positive coefficients respectively as range of. 1842(Sgs)~.3489(Aas)(p<.01), and also correlation coefficient with Sad were .4156(Acs)~.7280(Sgs)(p<.01), with Aa were .2711(Sgs)~.5096(Acs)(p<.01). Besides, the correlations between Sad's sub-factors and IQ were as range of .1406(Sen)~.2072(Sin)(p<.01), and correlations with Aa were .1368(Sen)~.3138(Sin)(p<.01), With Asc were as range of .4082(Sfr)~.6388(Sin)(p<.01). 2) There was a significant difference in Asc and Sad's sub-factors(adjustment toward school life : Sli, adjustment toward school environment : Sen, adjustment toward school teacher : Ste, adjustment toward school instruction : Sin, adjustment toward school friend : Sfr) by sex and level of school. And male students were higher than female students in Aas, Ins, Acs and Sms among achievement self-concept : Acs, academic ability self-concept : Aas and subject-matter self-concept : Sms) and well adjusted than female students in Sen and Ste among Sad's sub-factors. And middle school students were higher than high school students in Sgs, Ins, Acs and Sms among Asc's sub-factors and well adjusted than high school students in Sli, Sen and Ste among Sad's sub-factors. On the other hand, the well adjusted learner was high in IQ, Aa and Aas, Sms, Ins and Sgs among Asc's sub-factors, and learner who got higher level Aa was high in Asc and well adjusted toward Sli, Sen, Sfr and Ste among Sad's sub-factors than others(p<.01). The R^2(combined effect) of LRV(Sad, Aa and IQ) on Asc was 55.35%, and there were significantly relative effects of LRV on Asc respectively(Sad : 44.88%, Aa : 10.47, p<.01). And there were significantly relative effects of Sad's sub-factors on Asc respectively(Sin : 40.81%, Ste : 8.30% and Sli : 1.09%), the combined effect(R^2) of these sub-factors on Asc was 50.20%. There were significantly relative effects of LRV on Sad respectively(Asc : 44.88%, Aa : 0.8%), and the combined effect if these variables on Sad was 45.76%. There were significantly relative effects of Asc's sub-factors on Sad respectively(Sgs : 53.00%, Ins : 6.99%, Sns : 0.66%), and the combined effect(R^2) of these variables on Sad was 60.65%. Finally, the R^2 of LRV(IQ, Sad, Asc) on Aa was 44.92%, and the relative effects were 37.02%(IQ), 7.30%(Asc) and 0.60%(Sad). And there were significantly relative effects of Acs(25.97%) and Sms(2.79%) among Asc's sub-factors, and only Sin(9.85%) among Sad's sub-factors on Aa.

위염전은 위의 비정상적인 회전으로 생기는데 급성증에서는 진단이 늦어질 경우 치명적일 수도 있으나, 만성증의 경우는 비특이적 위장관 중상을 나타내며, 치료되지 않을 경우 수년 동안 증상이 지속될 수도 있다. 최근 저자들은 소화불량, 식후 상복부 동통을 주소로 내원한 환자에서 만성위염전 2 례를 경험하였기에 문헌고찰과 함께 보고하는 바이다. Gastric volvulus is an abnormal rotation of the stomach. Gastric volvulus may present as an emergency or as a chronic condition. Acute volvulus si potentially lethal if unrecognized, while a chronic volvulus may cause symptoms for years if not treated. Gastric volvulus may be more common than previously estimated. Approximately 700 cases have thus far been documented. In patients with vague upper abdominal pain, bloating, vomiting, early satiety and weight loss, chronic gastric volvulus are reported and the related literature reviewed. The clinical presentation, diagnosis, and treatment are treatment are discussed. Features of acute and chronic volvulus are compared.

본 연구는 우리나라 장수노인들의 식품섭취상태를 분석 평가하고 건강한 장수를 위한 식생활 지침의 설정을 위한 기초자료를 얻고자 수행되었다. 연구 대상은 경상북도 성주군에 거주하는 85세 이상 고령노인 중에서 일상 생활에 문제가 없는 224명이었으며 이들을 대상으로 반복 24시간 회상법을 이용하여 1년간 4회의 계절별 식품 섭취 조사를 실시하였으며 결과를 요약하면 다음과 같다. 계절별 식품군별 섭취량에 있어서 남자노인은 감자류의 섭취량이 여름철에 유의적으로 높고, 버섯류의 섭취량이 가을철에 유의하게 높은 것을 제외하고는 모든 식품군의 섭취량에 있어 계절별 차이가 나타나지 않았다. 여자노인의 경우 곡류, 당류, 두류, 채소류, 과일류, 조미료류, 음료 및 주류, 육류, 우유류, 어패류의 섭취량이 겨울철에 유의하게 높았으며, 종실류, 해조류, 난류의 섭취량은 계절에 따른 차이가 없었다. 조사 대상자들의 연평균 1일 총 식품 섭취량은 594.4±186.1 g이었으며 이 중에서 513.5±161.2 g(86.4%)는 식물성 식품군으로부터 섭취하였고 79.3±56.7 g(13.3%)는 동물성 식품군으로부터 섭취하였다. 섭취량이 가장 높았던 식품군은 곡류였으며그 다음이 채소류, 과일류, 어패류, 음료 및 주류, 조미료류, 두류, 육류, 우유류, 감자류 등의 순이었다. 장수 노인대상자들의 음식별 섭취빈도는 밥류에 있어서는 쌀밥의 섭취비율이 80.1~89.2%로 가장 높았으며 국과 찌개류에서는 쇠고기국, 된장국, 된장찌개의 섭취 비율이 높았다. 어육류 식품의 경우 조기구이의 섭취비율(9.4~12.7%)이 높았으며, 해조류 식품의 경우 김구이의 섭취비율(7.4~20.5%)이 높았고, 각 계절마다 계절식품의 섭취비율이 높았다. 김치류의 경우 배추김치의 섭취비율이 4계절 모두 70% 이상으로 높게 나타났다. 일품요리류는 손쉽게 조리할 수 있는 라면과 국수의 섭취비율이 높았다.<br/> 본 연구의 결과에서 경북 성주지역 장수 노인들의 계절별 식품 섭취량에 있어 겨울철의 식품 섭취량이 다른계절에 비해 유의하게 높았으며, 남자노인보다는 여자노인이 식품섭취에 계절에 의한 영향을 더욱더 많이 받는 것으로 나타났다. 또한 장수 노인들은 가공식품보다는 계절마다 제철에 생산되는 자연 식품의 섭취비율이 높았다. 전반적으로 장수노인들은 소식의 경향을 보였으며 이와 같은 소식습관과 신선한 식물성 식품들의 일상 섭취가 건강한 장수에 영향을 미쳤을 가능성도 있을 것으로 사료된다. The purpose of this study was to estimate food intakes of the long-lived elderly and to obtain the data for establishing dietary guidelines that may be recommended for the general population for the sake of longevity. The subjects of the study were 224 elderly people of age over 85 years living in Kyungpook Sung-Ju area who have no problem in daily living. The food consumption survey was carried out seasonally by the repeated 24-hr recall method for one year. The subject group for this study was composed of 58 males and 166 females, the average age being 87 years old. Food intakes of the winter were more than any other seasons. The mean daily total food intake per capita was 594.4 g, 513.5 g (86.4%) from plant foods and 79.3 g (13.3%) from animal foods. The sequence of high intakes of food groups were cereals, vegetables, fruits, fishes, legumes and meats. Boiled white rice, beef soup, soybean paste soup, soybean paste stew, broiled yellow croaker, kimchi, ra myon and broiled noodles were consumed most frequently. In conclusion, the subjects consumed much more plants foods than animal foods and consumed more natural and seasonal foods than processed foods and also showed food habits of eating small meals. Dietary habits of eating small meals containing abundant amount of fresh plant foods might partially contribute to the longevity of the subjects.

Oxo-thiomolybdate 화합물의 합성 및 탈황 촉매 반응의 활성에 관한 연구

구상만 한양대학교 에너지 ·환경기술연구소 1995 에너지·環境技術論文集 Vol.2 No.-

Oxidation of ?? by iodine yields the neutral adduct, Mo₂O₂S₄(DMF)₃, which is converted to heterobimetallic molybdenum sulfide complex by salt formation reaction. The cation exchange reaction of (Et₄N)[??] with NiCl₂ also produces a different type of heterobimetallic complex. The neutral adduct and two heterobimetallic complexes are used as precursors for thiophene HDS reaction. Major products in thiophene HDS are C₄ species for all precursors. Precursors obtained from heterobimetallic complexes show better catalytic activity than one that obtained from Mo₂O₂S₄(DMF)₃. Finally,γ-Al₂O₃ supported catalysts are more active for thiophene. HDS than carbon supported ones.
