Background: Cytomegalovirus(CMV) pneumonia is uncommon in hematologic malignancy patients and clinical feature has been unclear. Methods: The clinical features of 16 patients with hematologic malignancy who were diagnosed as CMV pneumonia from August 2008 to July 2014 were retrospectively analyzed. Results: 43% (7/16) patients were female and average age was 42.5. All patients were performed bronchoscopy at the time of diagnosis. CMV PCR titer from bronchial washing fluid ranged from 6.71 x 103 to 1.5 × 108 copies/ml, and mean value was 9.74 × 106 copies/ml. CMV culture from bronchial washing fluid was positive in 43% (7/16) patients. Cytology from bronchial washing fluid was consistent with CMV virus in 1 case and lung biopsy was done in 4 cases to confirm CMV pneumonia. 75% (12/16) patients with CMV pneumonia had coinfection (5 cases of bacteria, 3 of virus, 2 of pneumocystosis, 4 of aspergillosis, 1 of tuberculosis, 1 of non-tuberculosis mycobacteria, 1 of mycoplasma). 62% (10/16) patients had undergone hematopoietic stem cell transplantation and only 1 patient was in nadir state. All patients were treated with antiviral agent in CMV pneumonia patients. Ganciclovir was used as first line agent in 87% (14/16) patients and 4 patients had changed medication to foscarnet due to treatment failure or complication of ganciclovir. 12% (2/16) patients were treated with foscarnet as first line therapy. 25% (4/16) patients received CMV immunoglobulin. 28-day mortality was 50%. Conclusions: CMV pneumonia is one of the most fatal conditions rarely accompanied in hematologic patients. We analyzed clinical feature in hematologic malignant patients with CMV pneumonia including bronchoscopic findings, coinfection, treatment and prognosis.

Effects of Level and Degradability of Dietary Protein on Ruminal Fermentation and Concentrations of Soluble Non-ammonia Nitrogen in Ruminal and Omasal Digesta of Hanwoo Steers

Oh, Young-Kyoon,Kim, Jeong-Hoon,Kim, Kyoung-Hoon,Choi, Chang-Won,Kang, Su-Won,Nam, In-Sik,Kim, Do-Hyung,Song, Man-Kang,Kim, Chang-Won,Park, Keun-Kyu Asian Australasian Association of Animal Productio 2008 Animal Bioscience Vol.21 No.3

Four ruminally fistulated Hanwoo steers were used to determine the effects of level and degradability of dietary protein on ruminal fermentation, blood metabolites and concentration of soluble non-ammonia nitrogen (SNAN) in ruminal (RD) and omasal digesta (OD). Experiments were conducted in a $4{\times}4$ Latin square design with a $2{\times}2$ factorial arrangement of treatments. Factors were protein supplements with two ruminal crude protein (CP) degradabilities, corn gluten meal (CGM) that was low in degradability (rumen-degraded protein (RDP), 23.4% CP) or soybean meal (SBM) that was high in degradability (RDP, 62.1% CP), and two feeding levels of CP (12.2 or 15.9% dry matter). Ruminal fermentation rates and plasma metabolite concentrations were determined from the RD collected at 2-h intervals and from the blood taken by jugular puncture, respectively. The SNAN fractions (free amino acid, peptide and soluble protein) in RD and OD collected at 2-h intervals were assessed by ninhydrin assay. Mean ruminal ammonia concentrations were 40.5, 74.8, 103.4 and 127.0 mg/L for low CGM, high CGM, low SBM and high SBM, respectively, with statistically significant differences (p<0.01 for CP level and p<0.001 for CP degradability). Blood urea nitrogen concentrations were increased by high CP level (p<0.001) but unaffected by CP degradability. There was a significant (p<0.05) interaction between level and degradability of CP on blood albumin concentrations. Albumin was decreased to a greater extent by increasing degradability of low CP diets (0.26 g/dl) compared with high CP diets (0.02 g/dl). Concentrations of each SNAN fraction in RD (p<0.01) and OD (p<0.05) for high CP diets were higher than those for low CP diets, except for peptides but concentrations of the sum of peptide and free amino acid in RD and OD were significantly higher (p<0.05) for high CP diets than for low CP diets. Soybean meal diets increased free amino acid and peptide concentrations in both RD (p<0.01) and OD (p<0.05) compared to CGM diets. High level and greater degradability of CP increased (p<0.001) mean concentrations of total SNAN in RD and OD. These results suggest that RDP contents, increased by higher level and degradability of dietary protein, may increase release of free amino acids, peptides and soluble proteins in the rumen and omasum from ruminal degradation and solubilization of dietary proteins. Because SNAN in OD indicates the terminal product of ruminal metabolism, increasing CP level and degradability appears to increase the amount of intestine-available nitrogen in the liquid phase.

영상 시퀀스로부터 움직이는 객체의 검출은 비디오 감시, 교통 모니터링 및 분석, 사람 검출 및 추적 등에서 가장 기본적이며 중요한 분야이다. 안개와 같은 환경적 요인에 의하여 화질이 저하된 영상 속에서 움직이는 객체를 검출하는 일은 매우 어렵다. 특히, 안개는 주변 물체의 색상을 모두 비슷하게 만들고 채도를 떨어뜨려 배경으로부터 객체를 구별하기 힘들게 만든다. 이런 이유로 안개 영상 속에서 객체 검출 성능은 매우 낮으며 신뢰할 수 없는 결과를 나타내고 있다. 본 논문은 안개와 같은 환경적 요인을 제거하고 객체의 검출 성능을 높이기 위한 방법으로 안개 지수를 기반으로 안개 유무를 판단하고, Dark Channel Prior을 이용하여 안개 영상의 전달량을 추정하고 안개가 제거된 영상으로 복원하였으며 가우시안 혼합 모델을 이용한 배경 차분 방법을 이용하여 객체를 검출하였다. 그리고 제안된 방법의 성능을 비교하기 위해 안개 제거 전과 후의 영상에 대한 Recall 과 Precision을 측정하여 안개 제거에 따른 성능 향상 정도를 수치화하여 비교하였다. 결과적으로 안개 제거 후 영상의 가시성이 매우 향상되었으며 객체 검출 성능이 매우 향상됨을 알 수 있었다. Detecting moving objects from a video sequence is a fundamental and critical task in video surveillance, traffic monitoring and analysis, and human detection and tracking. It is very difficult to detect moving objects in a video sequence degraded by the environmental factor such as fog. In particular, the color of an object become similar to the neighbor and it reduces the saturation, thus making it very difficult to distinguish the object from the background. For such a reason, it is shown that the performance and reliability of object detection and tracking are poor in the foggy weather. In this paper, we propose a novel method to improve the performance of object detection, combining a haze removal algorithm and a local histogram-based object tracking method. For the quantitative evaluation of the proposed system, information retrieval measurements, recall and precision, are used to quantify how well the performance is improved before and after the haze removal. As a result, the visibility of the image is enhanced and the performance of objects detection is improved.

Oh, Young-Kyoon,Lee, Won-Man,Choi, Chang-Weon,Kim, Kyoung-Hoon,Hong, Seong-Koo,Lee, Sang-Cheol,Seol, Yong-Joo,Kwak, Wan-Sup,Choi, Nag-Jin Asian Australasian Association of Animal Productio 2010 Animal Bioscience Vol.23 No.12

This study was designed to investigate the effects of supplementation of spent mushroom substrates (SMS) on rumen fermentation and blood metabolites in Hanwoo steers. The experiment was conducted as a duplicated Latin square design with six Hanwoo steers ($600{\pm}47\;kg$), each permanently fitted with a ruminal cannula. There were three treatments; i) control (concentrates 4.8 kg +rice straw 1.2 kg/d), ii) Pleurotus eryngiia (PE) treatment (concentrates 4.8 kg+rice straw 0.73 kg+Pleurotus eryngiia 1.20 kg/d) and iii) Pleurotus osteratus (PO) treatment (concentrates 4.8 kg+rice straw 0.73 kg+Pleurotus osteratus 1.20 kg/d). There were no major effects of different dietary treatments on rumen parameters such as pH, ammonia-N, individual and total VFA production. Parameters of N utilization, including blood urea nitrogen (BUN), total protein and albumin levels, were not significantly different among the treatments, except for creatinine. Thus, the present results indicated that protein utilization was mostly unaffected by SMS treatments such as PE and PO, even though creatinine concentration was lower in PE compared with control and PO treatments (p<0.05). The present results indicate that Pleurotus eryngii and Pleurotus osteratus could be used as a forage source to replace 40% of rice straw without any negative effects on rumen fermentation and blood metabolites in Hanwoo steers.
