Bacterial translocation means the passage of viable bacteria from the gastrointestinal tract to normally sterile tissues such as the mesenteric lymph nodes and other internal organs. It is now clear that translocation is increased in bums and in injury including hemorrhagic shock. Total parenteral nutrition and elemental enteral diets are thought to be associated with atrophy of the intestinal mucosa and increased translocation. The purpose of this study was to determine whether or not the composition of nutrients effects on bacterial translocation in normal and burned rats. 54 male Sprague-Dawley rats were randomized to 3 groups of 18 animals each. Group Ⅰ was non-burned control rats, and group Ⅱ and Ⅲ were burned rats. Rats in group Ⅱ and Ⅲ were subjected to contact dermal bum of 10% and 20% each of their body surface area. All 3 groups were re-randomized to 3 subgroups of 6 animals each; subgroup 1 fed rat chow, subgroup 2 fed elemental diet(Energen®) and subgroup 3 fed oral TPN solution. Animals were fed respective diets ad libitum for 2 weeks, and then mesenteric lymph nodes, portal vein blood, and cecal content were aseptically obtained for culture. Bacterial count in mesenteric lymph nodes(MLN) of burned rats was significantly increased than that of non-burned rats(p=0.033). In burned rats, MLN bacterial count was the highest in the rats fed oral TPN (566.1±870.5/g vs. 270.1±382.4/g in the rats fed elemental diet and 164.9±184.7/g in the rats fed chow). Cecal culture in burned rats revealed a statistically significant increase in the cecal anaerobic count in the rats fed oral TPN when compared to the rats fed chow or elemental diet(p=0.003). There was close correlation between MLN bacterial count and cecal aerobes count(r=0.843, p=0.001). In conclusion, the type of nutrients had influence on bacterial translocation in burned animals partly by increasing the cecal bacterial population.

The transplantation of organ, tissues or cells between individuals of different species has been of increasing interest in recent years because the use of animals as organ and tissue donors as a source of transplants would overcome the severe and worsening shortage of human organs available for transplantation. However, There are some major hurdles to the clinical application of xenotransplantation; the immunologic response of the recipient against donor, the physiology of the graft, and the possibility that a xenotransplant might transmit an infection from the source to the recipient. This review describes the unique aspects of the immunological barrier to transplanting organs from non-primates such as pigs into humans, focusing especially on the mechanisms which contribute to immunorecognition, physiology of the rejection and infectious hurdles to xenotransplantation. This communication might be applied to overcoming these hurdles and the possibility that genetic strategies might be used to expand the potential applications of xenotransplantation for the treatment of human disease.

미래 사회를 대비하기 위한 개인의 개성을 존중과 창의적인 능력을 지닌 인간을 양성을 목적으로 충청남도 지역의 초 ㆍ 중고등학생들을 대상으로 한 창의력 경연대회가 공주대학교 과학교육연구소에서 개최되었다. 충청남도 초 ㆍ중 ㆍ 고등학생들을 대상으로 실시한 창의력 경연대회는 창조적 아이디어를 내어 스스로 문제를 해결해 나갈 수 있는 교육 프로그램을 제공하는 좋은 기회였음이 확인되었으나, 일부의 팀에서만 참신하고 재미있는 아이디어들이 제안되었다. 여학생의 참가자 수가 상당히 증가하였으며, 대체적으로 입상권의 학생들의 상당 부분이 여학생이라는 것이 특이할만하다. 학년이 올라감에 따라서 창의적인 아이디어를 내는 양이나 질에 있어서 뒤떨어지는 것으로 분석되었으며, 토론 학습의 적응력이 미흡하고 발표력 및 청취력에 있어서도 떨어지는 것으로 나타났다. 따라서 중 ㆍ고등학교의 학교교육에서도 학생들에게 프로젝트형 탐구학습 프로그램의 적용은 물론 토론식 수습을 통한 학생들의 사고의 전환의 기회를 제공해야 할 것으로 사료된다. The creativity competition was held to foster the creativity of elementary and secondary school students in the Institute of Science Education, Kongju national University. It was found that the creativity competition effected on the improvement of inventing creative ideas and problem solving activities. But, only some competitors participated in semifinal and final contests, presented original and interesting ideas. More female students participated in competition than last year. More female participants were awarded a prize than males. Totally, participants were defective in discussion and communication, and presentation and listening ideas. Increasing grades correlated inversely with creativity and originality. There is need of inquiry project teaming programs and presenting opportunities of conversion of thinking by discussing instructions in school

The toxicity and accumulation of mercury compounds in dentistry has been an issue of interesting concern. Relatively few data were available concerning the relation between toxicity and accumulation of inorganic mercury in vivo. The purpose of the study was to investigate the accumulation of mercury in rat tissues following exposure to different volumes of mercurous chloride. For this study, 44 Sprague-Dawley strain rats were divided into three large groups. The rats of Group I were supplied with a drinking water ad libitum, Grouop Ⅱ were fed 0.945mgHgCl_2 per 100gm of body weight and 3.780mg HgCl_2 per 100gm of body weight in Group Ⅲ. The rats were fed the mercurous chloride as solution type everyday via gastric lavage method for 2,4 and 6 weeks. The author collected the samples of hair, whole blood, kidney and liver and melted them in acid digestion bomb on the 2nd, 4th and 6th experimental week. The total mercury contents of hair, blood, kidney and liver were determined by Cold Vapour Atomic Absorption Spectrometry. The results obtained were as follows: The hair mercury contents of Group Ⅱ & Ⅲ were 2-4 times higher than that of the control . The mean mercury levels of whole blood were 0.09ppm(range 0.01-0.25) in control group, 0.34ppm(range 0.09-0.61) in Group Ⅱ and 0.76ppm (range 0.48-1.06) in Group Ⅲ during 6 weeks. The kidney was the main reservoir of mercury in body. The mean mercury levels of kidney were 0.16ppm(range 0.09-0.26) in control group, 60.98ppm(range 32.18-96.45) in Group Ⅱ and 102.45ppm(rang 73.89-142.09) in Group Ⅲ. There was significant difference of mercury content in kidney between groups(p<0.05). The mean mercury levels of liver throughout 6 weeks were 0.06, 2.46 and 3.46ppm in GroupⅠ, GroupⅡ and GroupⅢ, respectively. In control group, hair mercury content was the highest and kidney, whole blood, liver in descending order, but in GroupⅡ and Ⅲ, kidney mercury content was the highest and liver, hair, whole blood in descending order(p<0.05). There was significant correlationship between kidney mercury content and liver mercury content(r=0.8348, p<0.05), but there was no correlationship among the other samples.

肝組織에서의 Glucagon의 Cholesterol合成 抑制機轉에 對한 硏究

李根培,車鐘希,朴悅,高光三 朝鮮大學校 附設 醫學硏究所 1983 The Medical Journal of Chosun University Vol.8 No.1

The inhibitory mechanism of glucagon on hepatic cholesterol biosynthesis in rat was studied by the measurement of incorporation of tritium from ^(3)H₂O into cholesterol, and intermediary metabolite of lipids. But the rate of cholesterol synthesis was not affected. The hepatic acetyl-CoA carboxylase activity and malonyl-CoA concentration were decreased to 25~35% of control value during the same period after glucagon injection. These data indicates that one site of action of glucagon in regulating fat biosynthesis is at the acetyl-CoA carboxylase reaction.

原子力 發電所 使用後 核燃料 貯藏 方案의 比較 分析

李源根,金洸杓 慶熙大學校 1994 論文集 Vol.23 No.-

At present all the discharged spent nuclear fuells are stored in at-reator (AR) pools of each nuclear power plant in Korea, but most of the exciting AR pools will lose their full core reserve capacities in the late of 1990s Untill the long-term spent nuclear fuel management policy will be established, this cummulative spent nuclear fuels should be safely stored in an applicable storage facility. By this study results, the alternatives to solve this storage problem of the cummulative spent nuclear fuels are recommended as the followings : If the policy making would be done in the near future, the storage capacities of the existing pools would be expanded by the replacement of the old racks into or the installation of high density racks, and, if it could not be, a centralized wet or dry storage management of the spent nuclear fuels should be more reasonable.
