Background/Aims: Migration of neutrophil across the intestinal epithelium is a structural hallmark of active intestinal diseases. One of the characteristic histologic features of Helicobacter pylori (H. pylori) infection is neutrophil infiltration of the gastric mucosa. This study was aimed to establish an in vitro model system of transepithelial migration of neutrophil by H. pylori. Methods: Caco-2 cells were grown on polycarbonate membrane. Confluence and integrity were assessed by measuring the transepithelial electrical resistance (TER) and paracellular permeability of macromolecular marker. IL-8 mRNA expression was assessed after H. pylori infection by quantitative RT-PCR. Isolated neutrophils and H. pylori were applied to the basolateral and apical compartment in separate. Also neutrophil transmigration was assessed by light and electron microscopy. Results: Paracellular leakage of 3[H]-mannitol was negligible over TER 166 Ω×㎠. IL-8 mRNA expression increased after H. pylori infection. Neutrophil transmigration was increased by adding of N-formyl-methionyl-leucyl-phenylalanine or H. pylori. Conclusions: This in vitro model system could be applied to the study of pathogenesis of H. pylori infection. A further study of quantification of transmigrated neutrophils is demanded to reach a confirmation. (Korean J Gastroenterol 2003;42:20-26)

The purpose of this study was to suggest the future directions to improve the quality of teachers in early childhood physical education(ECPE). Self-administration questionnaire was administered to 108 teachers in order to investigate the current status of the teachers of ECPE. Results revealed that there were a limit of ability for teachers to provide the high quality service in physical education to preschooler. The following problems were raised on the analysis. First, there were large differences in the quality of teacher in ECPE due to variation in their education background. Second, from the evaluation of teachers` quality in the areas of lesson plan, evaluation, and instruction ability, it was found that the knowledge of understanding for children`s growth and motor development, of evaluating motor skill development, and of individualized instructional skill should be emphasized in the Teacher Education Program. In addition, the issues of accredited education system, standardized education curriculum, and expanded opportunity for practical experience and in-service program were discussed in order to improve the quality of the teachers in ECPE.

Recently, children`s height and weight are improved as compared to the past. However, the majority of children fails to meet minimum levels of physical fitness. In addition, as child obesity became a social problem, many professionals have been concerned about physical fitness education and the improvement of achieving physical fitness for the children through physical activities. However, little concerns has been stressed on developmentally appropriate physical fitness education for preschooler to stay physically fit in Korea. Childhood is an important period of promoting physical fitness and developing positive attitudes about exercise and physical activity. Fitness education should be started in early in child`s life to enhance children`s physical fitness during their early ages, and this will lay the ground work for achieving active lifestyle throughout adulthood. In this respects, this article reviews the needs of physical fitness of children and discusses ways to improve physical fitness for children. Also this article suggests potential directions of fitness education for children, and provides the strategies of promoting physical fitness for children.
Ecabet sodium이 Helicobacter pylori에 감염된 인체 위상피세포에서의 핵전사인자 활성과 chemokine 유전자 발현에 미치는 영향

목적 : H. pylori는 위점막 상피세포의 핵전사인자인 NF-κB를 활성화시키고 chemokine 발현을 증가시킨다. 궤양치료제로 알려진 ecabet sodium (ecabet)이 위점막 상피세포에서 항-염증반응을 나타내는 기전에 관해서는 알려진 바가 거의 없다. 이에 본 연구에서는 H. pylori 감염에 의한 위상피세포의 NF-κB 활성과 chemokine 발현에 ecabet가 어떤 영향을 미칠 수 있는지를 알아 보고자 하였다. 방법 : Hs74 Background : Helicobacter pylori stimulates nuclear factor-kappa B (NF-κB) activation and chemokine expression of gastric epithelial cells. Although ecabet sodium (ecabet), a locally acting anti-ulcer drug, is known to have an anti-H. pylori activity, the

Background/Aims: The aim of this study was to assess the clinical features and therapeutic responses of perianal lesions in Crohn`s disease. Methods: We retrospectively reviewed medical records of 94 cases with perianal lesions among 231 cases registered as Crohn`s disease in Seoul National University Hospital between January 1975 and June 2001. The cases were investigated after dividing into two different groups. One group included the cases registered between January 1975 and December 1996 and the other group between January 1997 and June 2001. Results: The perianal lesions were observed in 41% of the cases. Perianal lesions were more frequent in colonic Crohn`s disease after 1997, but not before 1996. Fistula was significantly prevalent, followed by abscess, fissure, and stricture. Perianal lesions preceded intestinal symptoms such as abdominal pain and diarrhea in 25% of the cases. The remission rate with non-specific conservative treatment (10%) was lower than that before 1996. The remission rate after specific treatment (77%) was higher than that after surgery (53%). In cases of specific treatment, cumulative relapse rates were 7% in 1 year and 39% in 5 years. Conclusions: Crohn`s disease should be considered in young male patients who have the refractory perianal lesions. Perianal lesions should be managed initially with medical treatment.
