식물체에서 당 조절 인자의 병 저항성 생리적 특성을 살펴보길 위하여, 원형질막에 존재하는 glucose 조절인자인 애기장대 AtPGR 유전자의 과발현 및 RNAi 형질전환체를 사용하였다[3]. AtPGR 유전자는 병원균 처리에 의하여 전사 발현양이 증가하였을 뿐만 아니라, JA와 SA 처리 시에도 AtPGR 전사 발현양이 증가함을 확인하였다. 과발현 형질전환체를 이용하여 병 저항성을 살펴본 결과, AtPGR 유전자는 병원균에 대해 저항성을 유도함을 알수 있었다. 또한 병원균 유도 증가 유전자로 알려진 PDF1.2 및 PR1 유전자 발현 양상을 qPCR을 통해 살펴본 결과, AtPGR 유전자는 PDF1.2 유전자를 SA 경로 하에서는 증가시키는 반면, JA 경로 하에서는 발현 증가량을 감소시키는 경향이 있음을 나타내었고, PR1 유전자의 발현은 JA 경로를 통해 조절할 것으로 생각되어진다. 이러한 결과를 바탕으로, AtPGR 유전자는 glucose 뿐만 아니라 병원균 반응에도 관련되어져 있음을 알 수 있다.

This study utilized Corpus-based Analysis process to compare the Cold Pathogen chapter in the 'English version of "Donguibogam"' to the 'English version of the "Shanghanlun"' translated by 罗希文 (Luo xi wen). Results of the linguistic analysis indicate that TTR, a ratio of number of types to number of tokens in the English version of "Shanghanlun" was 5.92% while TTR in the Cold pathogen chapter of English version of "Donguibogam" was 6.01%. It was also noted that the types of words frequently appearing in the two publications were the scientific name of medicinal herbs; the method of producing the herbal prescription (including terminology representing weights and measures); and Chinese descriptions of concepts considered important in both Korean and Chinese medicinal practices. Finally, it was possible to find points of comparison in naming of symptoms, diagnosis, prescriptions, and respective names of six meridians. Though the language difference is minimal, the vocabulary found in the Cold Pathogen chapter of "Donguibogam" was more diverse than Luo's translation of "Sanghanlun". In general, literal translation in keeping with the sense of original text was better performed in Luo's translation of the "Sanghanlun" whereas the English version of the Cold Pathogen chapter in the "Donguibogam" was more of a "free" translation.

폐렴은 호흡기계의 감염이고 원인균, 병인, 침범부위, 그 밖의 여러 가지 상황에 따라서 다양하게 분류된다. 비정형 병원균주 페렴으로 의심되어 내원한 46세의 남자 환자에서 이학학적 소견이나 혈액검사, 객담도말검사, 소변검사, 기생충검사, 기관지내시경검사, 침생검 등에서 특이할만한 원인균을 찾지 못했으며, 청진이상, 고열, 고혈압, 객담, 호흡곤란 등의 증상 또한 보이지 않았다. 세균성 또는 비정형 병원균의 광범위치료 항생제 복용이나 기생충제제를 복용하였으나 재발되었으며, 자연치유 및 재발이 반복되며 호전되었다. 반흔을 남기며 호전되고 새로운 부위에 결절이 재발하기를 반복하면서 서서히 없어지는 기간은 평균 20일 정도였다. 재발 이후 흉부엑스선 촬영과 흉부 고해상 전산화단층촬영을 추적 검사한 결과 흉부엑스선 촬영에서는 특이한 징후를 관찰하지 못했으나 고해상 전산화단층촬영에서는 병변이 호전되어가고 새로운 부위에 재발되는 모습을 관찰할 수가 있었다. 양측 하부 폐에 재발성 경과를 취한 비정형병원균주 폐렴이 의심되는 환자의 경우, 흉부엑스선 촬영 소견은 횡격막이나 간(Liver), 척추 등에 의해 숨기 때문에 추적검사로서 도움을 주는 데는 한계가 있으며, 흉부 고해상 전산화단층촬영 검사를 하여 비교하는 것이 바람직하다. 저자는 재발성 경과를 취한 비정형 병원균주 폐렴1예에 대한 문헌고찰과 함께 보고한다.

In plant pathology there is an increasing necessity for improved cytological techniques as basis for the localization of cellular substances within the dynamic fine structure of the host-(plant)-pathogen-interaction. Low temperature (LT) preparation techniques (shock freezing, freeze substitution, LT embedding) are now successfully applied in plant pathology. They are regarded as important tools to stabilize the dynamic plant-pathogen-interaction as it exists under physiological conditions. - The main advantage of LT techniques versus conventional chemical fixation is seen in the maintenance of the hydration shell of molecules and macromolecular structures. This results in an improved fine structural preservation and in a superior retention of the antigenicity of proteins. - A well defined ultrastructure of small, fungal organisms and large biological samples such as plant material and as well as the plant-pathogen (fungus) infection sites are presented. The mesophyll tissue of Arabidopsis thaliana is characterized by homogeneously structured cytoplasm closely attached to the cell wall. From analyses of the compatible interaction between Erysiphe graminis f. sp. hordei on barley (Hordeum vulgare), various steps in the infection sequence can be identified. Infection sites of powdery mildew on primary leaves of barley are analysed with regard to the fine structural preservation of the haustoria. The presentation s focussed on the ultrastructure of the extrahaustorial matrix and the extrahaustorial membrane. - The integration of improved cellular preservation with a molecular analysis of the infected host cell is achieved by the application of secondary probing techniques, i.e. immunocytochemistry. Recent data on the characterization of freeze substituted powdery mildew and urst infected plant tissue by immunogold methodology are described with special emphasis on the localization of THRGP-like (threonine-hydrxyproline-rich glycoprotein) epitopes. Infection sites of powdery mildew on barley, stem rust as well as leaf rust (Puccinia recondita) on primary leaves of wheat were probed with a polyclonal antiserum to maize THRGP. Cross-reactivity with the anti-THRGP antiserum was observed over the extrahaustorial matrix of the both compatible and incompatible plant-pathogen interactions. The highly localized accumulation of THRGP-like epitopes at the extrahaustorial host-pathogen interface suggests the involvement of structural, interfacial proteins during the infection of monocotyledonous plants by obligate, biotrophic fungi.

Clubroot disease is caused by the soil-born obligate plant pathogen Plasmodiophora brassicae. This pathogen can infect all cruciferous vegetables and oil crops, including Brassica rapa, B. oleracea, B. napus, and other Brassica species. Clubroot disease is now considered to be a major problem in Chinese cabbage production in China, Korea, and Japan. We collected several hundreds of P. brassicae infected galls from Korea, and isolated the single spore from the collection. For establishment of novel isolation, and mass-propagation methods for singe spore isolates of P. brassicae pathogen, we developed new filtration method using both cellulose nitrate filter and syringe filter. Accurate detection of P. brassicae pathogen in the field was done by using real-time PCR in the potential infested soil. When we tested the different pathogenicity on commercial Chinese cabbage varieties, P. brassicae from collected galls showed various morphological patterns about clubroot symptom on roots. To date, 8 CR loci have been identified in the B. rapa genome using the quantitative trait loci (QTL) mapping approach, with different resistant sources and isolates. We are trying to develop the molecular marker systems for detect all 8 CR resistant genes. Especially for the study on the interaction between pathogens and CR loci which are not well understood until now, genome wide association studies are doing using the sequenced inbred lines of Chinese cabbage to detect the novel CR genes.

The humans are under attack involving the hazardous environment and pathogen/biotoxin aerosol that is realistic concerned. A portable, fast, reliable, and cheap Pathogen and Biotoxin Aerosol threat Detection(PBAD) trigger is an important technology for detect-to-protect and detect-to-treat system because the man-made biological terror is a fast and lethal infection. The ultraviolet C(UVC) wavelengths light source is key issue for PBAD that is sensitive because of strong fluorescence cross section from fluorescent amino acids in proteins such as tryptophan and tyrosine. The UVC-light emitting diode(LED) is emerging light source technology as alternative to laser or lamps as they offer several advantages. This paper discussed about the design consideration of UVC-LED for the PBAD system. The UVC-LED and PBAD technology, currently available or in development, are also discussed.

Purpose: The purpose of this study was to determine factors related to clinical nurses' nursing intention for high risk pathogen infected patient. Methods: The participants were 230 clinical nurses from four university hospitals which located in B and D metropolitan cities. Data were collected from September 14 to 25 in 2015 and were analyzed using a hierarchical regression. Results: The mean of nursing intention score for high risk pathogen infected patient for the participants was $110.62{\pm}12.68$ (range 36~180). The most influential factor for nursing intention was professional self concept of nurses (${\beta}=.321$), and organizational group culture (${\beta}=.166$) was the next influential factor. The level of education and working department were also statistically significant contributors. Conclusion: It is necessary to increase clinical nurses' nursing intention for high risk pathogen infected patient to improve professional self concept of nurses and organizational group culture.
