Ebb & Flow 시스템을 이용한 Doritaenopsis 'Tinny Tender' 양액재배시 생장에 미치는 배양액 농도의 영향
최영일,한은주,박현춘,이용범,백기엽 충북대학교 한국과학재단 지정 첨단원예기술개발 연구센터 2002 연구보고서 Vol.6 No.-
심비디움 배양액을 4개 등급으로 나누어 나누어 Doritaenopsis 'Tinny Tender'를 ebb & flow 양액급수 시스템으로 9개월간 재배한 결과 생체중과 건물중은 고농도 배양액인 2S 처리구에서 가장 많이 감소하였으며, 1/2S, 1S, 3/2S 처리간에는 현저한 차이 없었다. 새로 증가한 엽수는 배양액 농도의 증가에 따라 증가하였으나 새로 증가한 엽면적은 1S처리에서 가장 많이 증가하였다. 식물체내 무기물 농도는 배양액 농도의 증가에 따라 증가하였다. 식물체 고사율도 배양액 농도가 증가할수록 증가하였는데, 3/2S, 2S 처리구에서 각각 5.8, 19.0%에 달하였다. 따라서 ebb & flow 시스템을 이용할 경우 배양액의 pH와 EC가 비교적 안정적이었고 식물체의 건물중 증가가 많이 이루어졌을 뿐만 아니라 고사율 또한 낮았던 1S 배양액이 Doritaenopsis의 생장에 가장 적절한 것으로 판단된다. This study was conducted to investigate the effect of nutrient solution strength on growth characteristics of Doritaenopsis 'Tinny Tender' in an ebb & flow system. Fresh and dry weights of plants grown with a 2S solution of Cymbidium standard solution were lower than those grown with other solution strengths. Fresh and dry weights of the plant were not significantly different among 1/2S, 1S and 3/2S solutions. Number of new leaves, chlorophyⅡ content and mineral content both in leaves and roots increased with increasing nutrient solution strength, while area of expanded new leaves was the greatest with 1S solution. Percentages of plant death increased as the solution strength increased, showing 5.8% in 3/2S and 19.0% in 2s solution, due to salt accumulation in the root zone.

Background: Myocarditis is a myocardial injury that can easily cause adolescent death. Traditional research models of animal invasion with viral components, lipopolysaccharide (LPS) or porcine myocardial myosin, among others, have the shortcomings of potential biological safety hazards and high animal mortality. Objective: To explore the construction of a novel myocarditis model with cyclosporine A and the potential genes and pathways associated with it. Methods: BALB/c mice were used in this study, and cyclosporin A and LPS were injected into the peritoneal cavity of mice. The successful establishment of the model was assessed by detecting serum myocardial injury markers and inflammatory factors levels, HE, IHC staining, and RT-qPCR methods. Key genes were obtained using the GSE35182 dataset from the GEO database and validated with the RT-qPCR method. Results: We found that a large number of inflammatory cells infiltrated the myocardium of mice in each group of Cyclosporin A constructed model, while the expression of inflammatory factor indicators was increased, and this model has the characteristics of high degree of local inflammation in myocardial tissue, low mortality, and safe and non-toxic treatment. Using GSE35182 data, we selected 18 Hub genes and validated Hub genes in myocardial tissue with RT-qPCR and found that multiple signaling pathways such as Toll-likereceptor signaling pathway(TLRs), Rap1 signal pathway(Rap1), and Chemokine signaling pathway may be involved in the development of myocarditis. Conclusion: Cyclosporin A can construct a new myocarditis model, and TLRs, Chemokines and Rap1 signaling pathways may be the core pathways of myocarditis.

A meteorological model, RAMS, and a commercial computational fluid dynamics (CFD) model, FLUENT are combined as a one-way off-line nested modeling system, namely, RAMS/FLUENT system. The system is experimentally applied in the wind simulation over a complex terrain, with which numerical simulations of wind field over Foyeding weather station located in the northwest mountainous area of Beijing metropolis are performed. The results show that the method of combining a meteorological model and a CFD model as a modeling system is reasonable. In RAMS/FLUENT system, more realistic boundary conditions are provided for FLUENT rather than idealized vertical wind profiles, and the finite volume method (FVM) of FLUENT ensures the capability of the modeling system on describing complex terrain in the simulation. Thus, RAMS/FLUENT can provide fine-scale realistic wind data over complex terrains.
