보육교사의 전염성 질환에 대한 지식 및 전염성 질환 아동 관리 실태
박선남(Park, Sun Nam),이영란(Lee, Young Ran),정영주(Joung, Young Ju),김경미(Kim, Kyung Mi) 한국보건간호학회 2010 韓國保健看護學會誌 Vol.24 No.1
Purpose: This study was conducted to investigate the knowledge of infectious diseases and the management of children with infectious diseases among daycare facility teachers. Methods: This study was based on survey questionnaires completed by 122 day care facility teachers from 36 daycare center sin one district in Seoul. Results: Seventy three (72.8%) of the participating daycare facility teachers had not received infectious disease prevention education. They recognized that they did not have enough knowledge of infectious diseases. The average knowledge level of infectious diseases was scored as 9.30 on a 0-30 scale, with 0 representing no knowledge and 30 expert knowledge, and compliance level of management of children with infectious diseases was scored as 4.29 on a 0-16 scale, with 0 present no compliance and 16 representing total compliance Confidence of management of children with infectious diseases (r=0.24, p=.031) and the compliance level of management (r=0.35, p=.001) were higher with increased knowledge of infectious diseases. Conclusions: Daycare facility teacher scan lack sufficient knowledge about b infectious diseases. The education about infectious diseases and management of children with infectious diseases is indispensable to prevent trans mission of infectious diseases in daycare facilities.

γ-aminobutyric acid (GABA)는 중추신경계에서 억제성으로 작용하는 주요한 신경전달물질이다. GABA 수송체(GAT)는 연접간격에 존재하는 GABA를 세포 내로 재 흡수하여 GABA의 농도를 조절한다. 그런데 GABA 수송체가 어떻게 조절되는지는 아직 밝혀지지 않았다. 본 연구에서는 효모 two-hybrid system을 사용하여 뇌의 주요 GABA 수송체인 GAT1의 C-말단과 특이적으로 결합하는 ubiquitin-specific protease 14 (Usp14)를 분리하였다. Usp14는 GABA 수송체 GAT1및 GAT2와는 결합하지만, 다른 GAT isoform과는 결합하지 않았다. GAT1과의 결합에는 Usp14의 C-말단부위가 필수적으로 관여함을 확인하였다. 또한 이 단백질간의 결합을 GST pull-down assay로 확인하였으며, 생쥐 뇌 균질액의 co-immunoprecipitation을 통하여 in vivo에서도 GAT1과 Usp14가 결합함을 확인하였다. 이러한 결과들은 Usp14가 GAT1과 결합하여 세포막에 존재하는 GAT1의 수를 조절하는 역할을 할 가능성을 시사한다. γ-aminobutyric acid (GABA) is the major inhibitory neurotransmitter in the central nervous system. GABA transporters (GATs) control extracellular GABA levels by reuptake of released GABA from the synaptic cleft. However, how GATs are regulated has not yet been elucidated. Here, we used the yeast two-hybrid system to identify the specific binding protein(s) that interacts with the carboxyl (C)-terminal region of GAT1, the major isoform in the brain and find a specific interaction with the ubiquitin-specific protease 14 (Usp14), a deubiquitinating enzyme. Usp14 protein bound to the tail region of GAT1 and GAT2 but not to other GAT members in the yeast two-hybrid assay. The C-terminal region of Usp14 is essential for interaction with GAT1. In addition, these proteins showed specific interactions in the glutathione S-transferase (GST) pull-down assay. An antibody to GAT1 specifically co-immunoprecipitated Usp14 from mouse brain extracts. These results suggest that Usp14 may regulate the number of GAT1 at the cell surface.
