To determine the characteristic double contrast barium enema findings of ileo-cecal and colonic tuberculosis and to make differential diagnosis from other bowel inflammatory disease. Sixty-seven patients confirmed as ileo-cecal and/or colonic-tuberculosis in six hospitals were evaluated retrospectively. The diagnosis was proven by endoscopic biopsy, surgery, and clinical follow up. Nine of 67 patients were excluded because radiologic findings were normal though endocopic biopsy examinations resulted in tuberculosis. Histopathological diagnosis were madein 58 cases as follows: endoscopic biopsy(n=29), operation(n=12), follow up examination(n=14), tissue culture(n=1), laparoscopic biopsy(n=2). There were 30 men and 28 females. The mean age were 36 yrs(range:16-67), 34 patients were in the second and third decade. The distribution of lesions, morphological characteristics, mucosal changes, ulcer shape and depth, associated with other tuberculous lesion, multiplicity were retrospectively analyzed in the findngs of double contrast barim enema. The commonest clinical symptoms were abdominal pain(n=35, 60%) and diarrhea(n=18, 31%). The chest radiography revealed association of pulmonary tuberculosis in 39 cases. Tuberculous lesions of other organs except chest were present in five cases. Double contrast barium enema findings showed a thickening and irregularity of intestinal mucosal fold(n=29, 50%), bowel contraction and/or shortening(n=26, 45%). There were small, nodular, superficial ulcers in the case of ulcer depth less than 2 mm in the depth. As many as 39 cases(67%) in this series had two or more lesions in the intestinal tuberculosis. The involved segment revealed symmetrical feature(n=21, 36%). Inflammatory pseudopolypoid lesions were noted in 30 cases(52%). The ileo-cecal region was involved in 38 cases(66%). The ascending colon(n=25, 43%) was the second commonest site with or without contiguous cecal involvement. Lesions in terminal ileum, ileo-cecal valve, transverse colon, descending colon and appendix were seen in 19, 18, 18, 12 and seven cases, respectively. Among 18 cases of ileo-cecal valve lesions, there were incompetency in nine cases(16%) and wide gapping in four cases(7%). In 14 cases, tuberculous enterocolitis was diagnosed by clinical follow-up and double contrast barium enema study. 12 out of 14 cases, the findings of double contrast barium enema of tuberculous enterocolitis were normalized after anti-tuberculous medication. However, two cases showed more aggravated state than before due to inappropriate treatment. Double contrast barium enema plays an important role in the diagnosis of tuberculous enterocolitis, determines the type, site and extent of the involvement and helps in treatment guide by using sequential studies.

Helicobacter pylori infection was the cause of chronic gastritis, duodenal ulcer and gastric MALT lymphoma. The eradication rates of H. pylori using antibiotics are around 80%. Lactobacilli have been demonstrated to have in vivo and in vitro inhibitory effects on H. pylori infection. We aimed to evaluate the inhibitory effect of L. lactis CBT-8 and its extract on H. pylori in human stomach. Thirty-five H. pylori-infected volunteers(30-49 yr)were randomized into two groups which were treated with L. lactis CBT-8 and its extract(Group A n=17) or milk containing L. lactis CBT-8(Group B, n=18). They underwent 13C-urea breath tests before and after treatment. The DOB30 of group A(n=14) was decreased 41.0% after treatment(26.0±4.9 before, 15.3±2.1 after treatment)(p<0.05). the DOB30 of group B(n=13) was decreased 22.3% after treatment(22.0±2.2 before, 17.1±1.7 after treatment)(p<0.05). In conclusion, L. lactis CBT-8 was effective in suppressing H. pylori infection in human stomach.

본 연구에서는 교사-유아 간 애착안정성 정도에 따라 유아의 스트레스 정도 및 유아의 스트레스 대처행동에 어떠한 차이가 있는지 알아보고자 하였다. 연구 문제에 따른 연구 결과는 다음과 같다. 첫째, 교사-유아 간 애착안정성 정도에 따른 유아의 스트레스 정도에는 통계상 유의미한 차이가 없었고, 유아 스트레스 하위 영역인 교사, 또래, 학습 환경에서도 통계상 유의한 차이가 없는 것으로 나타났다. 다만 학습 활동영역에서 교사-유아 애착안정성이 낮은 유아 집단이 높은 집단보다 스트레스를 더 많이 받는 것으로 나타났다. 이러한 결과는 교사-유아 애착안정성 정도에 따라 교사, 또래,학습 환경 요인과 관련된 유아 스트레스에 차이가 없으며, 교사-유아 애착안정성이 높을수록 유아가 학습활동 요인과 관련된 스트레스를 덜 받는다는 것을 알 수 있다. 둘째, 교사-유아 간 애착안정성 정도에 따른 유아의 능동적, 수동적, 신비적 스트레스 대처행동 양식에서 통계상 유의한 차이가 나타났다. 교사-유아 간 애착안정성 정도가 높은 집단이 능동적 대처를 더 많이 하고, 교사-유아 간 애착안정성 정도가 낮은 집단이 수동적 대처와 신비적 대처를 비교적 더 많이 한다는 것을 알 수 있다. Due to lack of systemic program regarding physical activity in children, the study is to identify the constitution and development of the Natural Physical Activity Program by offering environmentally friendly elements such as wind, sun, mountain, sea, river, tree, flower, field for children. We expect children to learn the relation with nature, respect for life, understanding and love, importance of working together, and etc. The research questions for the purpose of this study are as followed: First, this study is going to identify the overall awareness and its needs of the Natural Physical Activity Program among preschool teachers. Second, we will look over how we can develop such program for preschool teachers. And a direction proposal on Natural Physical Activity Program. About 250 preschool teachers resided in Busan and Gyug-nam province were urged to participate in a research questioning their awareness and needs of the program. Among 250 preschool teachers, we choose 20 of them to interview about the goal, plan and development direction of the program. The result of the study is following as: First, most of the preschool teachers have a positive view on the Natural Physical Activity Program, and they agree that the program is highly needed to use. However, it is urge that overall education environment need to be improved to achieve its goal of the program. Second, the interview on the development direction is categorized as need, development direction, teaching method, evaluation method, activity, problem, improvement, solution, and etc. and, Third, the contents of the program include environmentally friendly elements such as wind, sun, mountain, river, sand, tree, flower, field to induce children’s interest and whole-person education. The contents of the program are expected to deliver hands-on experience for children. And also, the program includes physical activity using a nature object. Based on the potential problems we identified, a next study is expected to deal with following points. First, more empirical research is needed to prove the effectiveness of the program in a broad way by proposing a program that can be applicable at child-education center. Second, the study developed contents to make children feel enjoyable about nature. Unfortunately, in-depth research and development of such program is not sufficient. In this respect, more continuous research on Natural Physical Activity Program is required and need to be widely established.

Orostachys malacophyllus F. has been applied in Chinese medicine as well as in folk remedy. Its chemical composition and pharmacological actions have not reported yet. But, sometimes, it was used in treatment for the stomach or lung cancer. This study was attempted to investigate the effects of the water fraction separated from alcohol extract of the plant on the renal functions of rabbits. After cannulation of carotid artery, jugular vein and ureters were prepared for the recording of blood pressure, the infusion of the water extract(0.005%) or the hypotonic saline(0.45%), and the collection of the urine, respectively. The hypotonic saline was infused to hydrate the rabbits, and the mixed solution of hypotonic saline, PAH, and inulin was infused to measure the glomerular filtration rate(GFR) and renal plasma flow (RPF). After the hydration, the changes of urine volume were obsereved during the infusion of the water fraction for 1 hour, and during the infusion of hypotonic saline for 80min. And the concentration of PAH or inulin in the urine and blood was measured by the method of Smith and the method of Schreiner, electrolyte concentration by flamephotometer, and the osmolar conentration by osmometer, respectively. The results were summarized as follows: 1. Urine volume, GFR, and RPF were decreased significantly by the infusion of water fraction, and thery were not recovered to control values after the exchange to hypotonic saline. 2. Filtration fraction was increased by water fraction. 3. Water fraction decreased the plasma clearances of electrolytes and the osmolar substances, and increased the negative free water clearance. 4. Water fraction increased the reabsorptive rate(%)of potassium, and decreased the excretory amount of Na or K. And it was decreased the ratio of Na/K excretion. From the above results, it was suggested that water fraction has the antidiuretic effect and its mechanism is primarily caused by the change of the renal hemodynamics.

최상준,강혜진 인제대학교기초과학연구소 1999 자연과학 Vol.3 No.-

Ni(111)표면위의 CO₂흡착자리에 따른 흡착세기는 di-ο⑴, 1-fold, 3-fold,2-fold, π/μ,μ, 그리고 π-site순이다. di-ο⑴ 흡착자리에서는 <OCO가 148。인 찌그러진 CO₂분자구조를 가진다. 1-fold, 2-fold 및 3-fold의 경우는 CO₂분자중 산소의 한 끝이 고체표면과 결합하는 수직형태의 화학흡착이 일어남을 알았다. CO₂분자가 찌그럼짐은 2πu-obital과 섞임이 일어나기 때문이다. We calculated seven coordinated mode of binding site on Ni(111) surface; di-ο π,μ,π/μ, 1-fold, 2-fold, and 3-fold. Calculated binding energies are 2.31eV, 0.81eV, 1.50eV, 1.62eV, 2.27eV, 1.91eV, and 2.19eV, respectively. Then we have found that the binding energy is strongest at the di-ο(1) site. The adsorbed molecular CO2 of the di-ο(1) site on the Ni(111) surface is strong chemisorption and chemisorbed CO2 bends because of metal d-mixing with 2πu CO2 orbital.

Cyclophosphamide lays restraints upon production of fibroblast and collagen fiber and reduce wound burst strength by acting on fibroblast in acute inflammatory phase. Vitamin A is known to increase inflammatory reaction by exerting an effect upon inflammatory cells in the beginning of the wound healing process. It shows contrary effect to cyclophosphamide. In order to study the influence of vitamin A over wound healing delay induced by cyclophosphamide in rats, we observed and compared the wound burst strength of cyclophosphamide and vitamin A combined treated group with those of control and cyclophosphamide treated group. Wound burst strength of each group was measured in the skin segments of 2×4cm obtained from the operation sites at the 3rd, 5th, 7th and 14th postoperative days after making 5cm incision and suture at the back of 72 rats. Results of the experiment are as follows; 1. Wound burst strength in control group increases slowly as days go by and shows trends of sudden increase between the 5th and 7th postoperative days. 2. Wound burst strength in cyclophosphamide treated group is markedly less than that in control group. 3. Wound burst strength in cyclophosphamide and vitamin a combined treated group shows similar level to that in control group. 4. Body weight in cyclophosphamide treated group reduces gradually as days go by. But there's no weight reduction in cyclophosphamide and vitamin A combined treated group. Judging from these results, we found the fact that vitamin A could prevent or recuperate the side effects of cyclophosphamide, delay of wound healing and worsening of general condition.

This study investigated the experience and practice of elementary school students on nutrition education. The data were collected from 217 male and female students attending 5-6th grade elementary schools in Seoul and Kyunggi-Do from March to June 2007, interviewing face to face by a nutrition teacher and 3 interns of a nutrition teacher. The results were as follows: 86.5% of the subjects learned about ‘Table etiquette’, ‘Reasons for eating fruits and vegetables’ (78.7%), ‘Food waste and environment’ (72.3%), ‘Healthy snacks’ (55.7%), ‘Food sanitation’ (52.3%), ‘Food culture of foreign countries’ (48.1%). Nutrition education experience was significantly different by gender. A total of 43.5% boys responded that they never learned about ‘basic food preperation’ (p < 0.01). They had learned ‘Nutrients for body’ and ‘Food waste and environment’ in school, ‘Healthy weight loss’, ‘Food culture of foreign countries’, ‘Food circulation’ on television, Most content (‘Table etiquette’, ‘Simple cooking’, ‘Food sanitati n’, ‘Eating behaviors for health’, ‘Reasons for eating fruits and vegetables’, ‘Healthy snacks’) was learned from parents. The practice after nutrition education was higher in ‘Table etiquette’ (2.14), ‘Eating fruits and vegetables’ (2.07) than others compared with education experience. The most reason of non-practice on nutrition information was ‘Troublesome’. In ‘Nutrients for body’, a boy answered ‘Difficult for practice’ 20.0%, a girl answered ‘Difficult to understand’ 32.6%, showing a significant difference between the gender groups (p < 0.001). They remembered the ‘Nutrients for body’ (49.6%), ‘Food sanitation’ (44.5%) because of ‘important content’,‘Basic food preparation’ (40.6%), ‘Food culture of foreign countries’ (36.3%) because of ‘interesting content’, ‘Healthy weight loss’ (52.0%), ‘Eating behavior for health’ (44.5%) and ‘Healthy snacks’ (33.7%) because of ‘need for my health’.

Background: People with insulin resistance has a higher risk of developing cardiovascular disease. This leads to the importance in diagnosing metabolic syndrome. The incidence of metabolic syndrome has increased significantly in korea because of an increased population of obese people and also the incidence of DM. There have been many studies done on the incidence of metabolic syndrome in the general population. Therefore, the authors have designed this study to identify the incidence of metabolic syndrome in patients with type 2 DM and also the associated characteristics in that population. Methods: The study included 169 adults over the age of 20 (84 males and 85 females) admitted to the endocrinology department of Chosun University between Jan, 1st 2005 and May, 31st 2006. Out of the people diagnosed with type 2 DM people were excluded when any of the physical measurements (height, weight, blood pressure, abdominal circumference) and blood measurements (TG, HDL-cholesterol, fasting blood sugar) were insufficient and when the patient was taking any drugs other than anti-hy-pertensive agents and oral anti-diabetic agents. Obesity and the other risk factors were defined by the Asian-Pacific guideline and 2001 ATP III of NCEP, respectively. Result: The each prevalence according to the metabolic syndrome criteria of the type 2 DM patients showed low HDL cholesterolemia with the highest incidence of 57.4% followed by hypertng1yceridemia(52.0%), obesity(40.9%) and hypertension(33.0%). The each incidence of diagnostic criteria in metabolic syndrome according to sex was different, In males, hypertriglyceridemia was the highest with the incidence of 57.7% followed by low HDL-cho1estero1emia(49.5%), obesity(40.9%) and hypertension (30.0%). In women, the incidence were low HDL-cho1estero1emia(64.8%), hyperthg1yceridemia(47.6%), obesity(45.0%) and hypertension(36.0%), in a descending order. The analysis between the diagnosis of metabolic syndrome in type 2 DM patients and the criteria showed that hyperthglyceridemia (correlative value 0.575) had the highest correlation followed by low HDL-cholesterolemia (correlative value 0.446), obesity (correlative value 0.350) and hypertension (correlative value 0.410). All the correlations were statistically significant with a p-value less than 0.01. Conclusions: Type 2 DM is a important factor of metabolic syndrome based on insulin resistance. The control of blood glucose with prevention and early diagnosis of the other factors related to metabolic syndrome in type 2 DM is important for preventing cardiovascular complications.
