`Background : Pancreatoduodenectomy is a widely used technique in the treatment of periampullary, duodenal and cephalic pancreatic disease. Although many improvements have been made in operative technique and posmiddleerative care, pancreatoduodenectomy remains a technically difficult procedure attended by relatively high morbidity and mortality rates. Materials and methods : The hospital records of 51 patients who underwent pancreatoduodenectomy at the Chosun University Hospital between 1994 and 2001 were reviewed. Clinical data and the following morbidity and mortality were recorded The risk factors were analyzed by a Chi-square test. Results : Fifth decade was the most prevalent ages (43.1%) The mean age was 59 years (ranging from 29 to 78) and the male to female ratio was 26 to 1. The periampullary cancer was the most reason to operation (86%) and injury due to trauma, adenocarcinoma of stomach, colon cancer, chronic pancreatitis in order Posmiddleerative complications were developed in seventeen patients and anastomotic leakage was the most common complication Death within a month after operation was 3 (5.8%) and the one of the cause of death was leakage in two patients, the other cause was intraadbominal bleeding in one patients. The cardiovascular disease, pulomnary problem, diabetes, level of bilirubin were checked preoperatively and showed no statistical difference in the posmiddleerative morbidity. The other factors such as amount of bleeding, operation time were not influencing posmiddleerative complications. The occurrence of leakage in eight cases of drainage tuve inserted into the pancreaticojejunostomy site was not different from no tuve insertion statistically Conclusion: old age of the patients, diabetes mellitus and massive intraoperative hemorrhage are the risk factors influencing the results after pancreatoduodenectomy. Morbidity and mortality after pancreatoduodenctomy can be devreased if a prudent selection of paients is made and the operation is performed by accomplushed surgeon.

Purpose: By the definition of UICC TNM classification (fifth edition), the nodal stage of gastric cancer is based on the number of metastatic lymph nodes, which is influenced by the number of resected lymph nodes. And individual differences in the number of resected lymph nodes had been observed in patients with gastric cancer. The aim of this study is to verify the factors which are associated with the difference in the number of resected lymph nodes in patients with gastric cancer. Methods: We reviewed 613 patients with gastric cancer who underwent curative resection and D2 lymph node dissection with 15 or more resected lymph nodes. The number of resected lymph nodes was analyzed according to the characteristics of patients, the types of operation and prognostic factors of gastric cancer. Results: The mean number of resected lymph nodes per patient was 33.0 (median: 31.0, range: 15-88). The number of resected lymph nodes was significantly associated with the types of operation, the location and size of tumor, macroscopic types, depth of tumor invasion and the number of metastatic lymph nodes. Patient's age, gender and the histopathological finding's had no relationship with the number of resected lymph nodes. Conclusions: The number of resected lymph nodes from gastric cancer was different in each patient despite of same D2 lymph node dissection and it was associated with several prognostic factors of gastric cancer.

Purpose: The purpose of this study was to analyze students' expectance demand towards high school physical education teaching. Methords : 392 participants randomly selected from one girls' middle school and one girl's high school in each of five tracts and then selected two classes from each of the schools. They were asked to respond to a simple Questionnaire about their views on the present physical education teaching. Results : Results showed that about one third of the participants would not choose physical education if the program were offered as an optional subject. Both male and female students ranked psychomotor domain as the top priority among the various learning objectives. Male students favored soccer and basketball while their counterparts liked badminton and volleyball. Over three-fourths of the participants suggested that students' opinions should be considered when teachers plan their program. Conclusion : The results of this study recommended that physical education teaching should be designed with considerations for professional values, societal changes as well as students' expectance on the design of physical education.
수목추출물의 생리활성에 관한 연구(Ⅹ) : 헛개나무 목부의 항균활성 물질 Antifungal Compounds of Hovenia dulcis

항균활성이 우수한 혓개나무 목부 에탄올 조추출물로부터 7종의 화합물을 단리하였으며, 기기분석 결과 flavonoid인 5-hydroxy-7methoxyflavone를 비롯하여 5,7-dihydroxyflavone (chrysin). 5,7-dihydroxyfla-vanone(pinocembrin), 3,5,7-trihydroxyflavanone (pinobanksin), 3,4',5,7-tetrahydroxyflavanone (aroma-dendrin)과 stilbenoid인 3-hydroxy-5-methoxystilbene과 3,5-dihydroxystilbene (pinosylvin)으로 각각 동정되었다. 이들 단리물질에 대한 항균활성을 조사한 결과 stilbenoid인 3-hydroxy-5-methoxystilbene이 공시균주의 생장을 완전히 저해하여 단리물질 중 활성이 가장 높은 것으로 나타났다. 그 다음이 pinocembrin과 pinosylvin으로 Cryphonectria parasitica, Trametes versicolor, Tyromyces palustris 그리고 Trichoderma viride에 대한 높은 균사생장억제율을 나타내어 활성이 우수한 것으로 나타났다. 그러나, flavonoid인 pinobanksin, 5- hydroxy-7-methoxyflavone, chrysin, 그리고 aromadendrin은 항균활성이 낮은 것으로 나타났다. 이상의 결과, 헛개나무 목부 에탄올 조추출물의 높은 항균활성은 3-hydroxy-5-methoxystilbene과 pinocembrin, 그리고 pinosylvin에서 유래된 것으로 사료되었다. Antimicrobial activities of plant extractives were investigated to develop a natural fungicide. Two stilbenoids and five flavonoids were isolated from wood extractives of Hovenia dulcis (Rhamnaceae) which had been selected due to its high antifungal activity among the tested species. The chemical structures of isolated compounds were determinded as : 5-hydroxy-7-methoxyflavone, 5,7-dihydroxy-flavone (chrysin), 5,7-dihydroxyflavanone (pinocembrin), 3,5,7-trihydroxyflavanone (pinobanksin), 3,4',5,7-tetrahydroxyflavanone (aromadendrin), 3-hydroxy-5-methoxystilbene and 3,5-dihydroxystilbene (pinosylvin) on the basis of Mass and NMR spectroscopic data. According to the results of antifungal test, 3-hydroxy-5-methoxystilbene was evaluated as the strongest antifungal compound among the tested compounds and next were pinocembrin and pinosylvin, but those also had high hyphal growth inhibition activities against C. parasitica, T. versicolor, T. palustris and T. viride. However, pinobanksin, 5-Hydroxy-7-methoxyflavone, chrysin and aromadendrin showed very low antifungal activity. In this regard, it could inferred that high antifungal activity of wood extractives of H. dulcis were derived from 3-hydroxy-5-methoxystilbene, pinocembrin and pinosylvin, respectively.
