AUDIT-K(한국형 알코올 중독 간이선별 검사법)을 이용하여 일상적으로 생활하고 있는 상당수의 잠재적인 위험 음주자들을 선별 할 수 있었으며 연령, 종교, 결혼여부, 직업, 소득음주사망 가족력, 음주시작 연령, 흡연, BMI(체질량지수)는 통계적으로 유의한 차이가 없었으며, 학력, 음주기간만 통계적으로 유의하였다. 이러한 결과는 교육을 더 받은 사람의 남성이 알코올 소비가 더 높다고 한 선행연구와 부합하는 결과를 나타내었으며 교육수준 또한 무엇을 어떻게 배웠는가에 따른 차이를 살펴 볼 필요가 있음을 시사하며, 교육에 따른 알코올 소비도 각각 다른 결과를 나타냄을 알 수 있다. 또한 나이가 적을수록 술을 많이 마시면 음주기간이 길어질 것이고 기존의 음주시작 연령에 대한 연구와 일치하는 결과가 나타났다. 본 연구에서는 음주 기간이 알코올 사용 장애의 가장 큰 요인이었으며 음주 기간을 단축하기 위한 방법으로는 음주 시작연령을 최대한 늦출 수 있는 국가 정부 제도의 대책 및 교육이 필요하다고 생각된다.

In this study, β-1,3/1,6-glucan, lactic acid bacteria, and β-1,3/1,6-glucan+lactic acid bacteria were tested for 10 weeks using an immunodeficient animal model infected with LP-BM5 murine AIDS virus On the immune activity. Cytokines production, plasma immunoglobulin concentration, T cell and B cell proliferation were measured. As a result, the T cell proliferative capacity which was weakened by immunization with LP-BM5 murine AIDS virus increased significantly T cell proliferative capacity compared with the red ginseng control group. B cell proliferative capacity was significantly higher than the infected control group. Increased B cell proliferation was reduced. In the cytokine production, IL-2, IL-12 and IL-15 in the Th1-type cytokine increased the secretion of IL-2, IL-12 and IL-15 compared to the infected control. The proliferative capacity of the treated group was higher than that of the mixed treatment group. TNF-α was significantly decreased compared with the infected control group. The IL-4, IL-6 and IL-10 levels were significantly inhibited in the infected control group and the Th1/Th2 type cytokine expression was regulated by immunohistochemistry. IgE, IgA, and IgG levels were significantly lower in the immunoglobulin secretion assay than in the control. As a result, the immunomodulatory effect of β-1,3/1,6-glucan+lactic acid bacteria was confirmed by mixing with LP-BM5 murine AIDS virus-infected immunodeficient animal model.

EP was obtained through 20% ethanol extraction of Pueraria lobata root, and the fermented form of EP, FEP, was prepared from the EP after incubating with Lactobacillus rhamnosus vitaP1. There was no significant toxicity by EP and FEP up to 1000 ㎍/㎖ in NIH-3T3, HaCaT, and B16F10 cells. In addition to antioxidant potentials of EP and FEP determined by DPPH and ABST assays, we confirmed increase of procollagen type I and elastin synthesis by supplementation of the EP and FEP at the concentration of 50 ㎍/㎖ using ELISA kits. The protein expression levels of matrix metalloprotease (MMP)-1, -3, and -9, those are involved in the degradation of collagen or other skin matrix proteins, were remarkably suppressed while their inhibitory protein metallopeptidase inhibitor 1 (TIMP-1) was greatly up-regulated by supplementation of the EP and FEP at a concentration of 50 ㎍/㎖. Taken together, both EP and FEP supplementation could be involved in the suppression of the skin wrinkle formation through inhibiting degradation of collagen and stimulating the synthesis of collagen and elastin. The results showed that the anti-wrinkle potential of the EP and FEP will be a promising candidate for developing cosmeceutical compounds or products.

Background : Management of air temperature are known to primarily affecting on physiological properties and yield in plant. Methods and Results : The effect of air temperature on characteristics of photosynthesis and chlorophyll fluorescence in Schisandra chinensis Baillon were investigated under controlled temperature using growth chamber. Net photosyntheis rate, transpiration was measured at 1,000 μmol m-2 s-1 of photon flux density and chlorophyll fluorescence was analyzed by OJIP method. Net photosyntheis rate and transpiration rate was higher in treatment of 25℃. As results of chlorophyll fluorescence by OJIP analysis, maximum quantum yield (Fv/Fm) of photosystem II (PSII) and PIabs was higher in treatment of 25℃ which reflects the relative reduction state of PSII. But in treatment of 35℃ the relative activities per reaction center such as ABS/RC, DIo/RC were higher than in treatment of 25℃ which implied that the relative reduction of electron transport at PSI and increasement of photo inhibition at reaction center. Conclusion : This result implies that 25℃ of air temperature may be a adequate temperature to improving the efficiency of photosynthesis through controlling a photosystem in Schisandra chinensis Baillon.

Recently there are increasing numbers of people participating in sports activities. Accordingly, the rate of sports injuries is increasing as well. In this light, this study was conducted to investigate the extent of acute damage and its forms by examining the current state of patients with sports injuries. This research study was conducted between January of 2008 and December of 2010 in Chosun University Hospital through retrospective review of the medical records of patients with sportsrelated injuries. The total number of patients with sports injuries who visited the emergency center was 887. The number of male patients was 726 (81.85%), far more than the number of female patients (18.15%). More than half of the patients, accounting for 419 (47.23%), had injuries on their face; second and common parts, in which injuries occurred, were upper and lower body, accounting for 146 (16.45%) and 193 (21.75%), respectively. The majority of patients did not undergo surgical treatment. Only 113 (12.73%) patients underwent surgical treatment. In addition, more than 80% of them were not hospitalized but 170 of them needed to be hospitalized. Most sports injuries occurred in young male patients. This can interrupt participation in sports activities for a long time and result in lower quality of life. Hence proper preventative measures and scientific treatment methods are needed.

Perilla frutescens (L.) is an edible plant, not only used as s food ingredient, but also in skin cream, soaps, and medicinal preparetions. ‘Atom-Ros’, a perilla (Perilla frutescenc (L.) Britt. cv. Chookyoupjaso was developed in 1995 by 200 Gy gamma irradiation-mutagenesis. This new cultivar has high rosmarinic acid content more than two fold compare with ‘Chookyoupjaso’ control. The observed phenotypical difference was changed leaf color of the ‘Atom-Ketone’ from violet to green. The yield potential of this cultivar (123.5 kg/10a) was 2.14 fold higher than that of ‘Chookyoupjaso’ (57.65 kg/10a). The methanol extracts of ‘Atom-Ros’ were tested for inhibition of nitric oxide (NO) production in lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophase cells. Atom-Ros showed significant inhibition of NO production. This rosmarinic acid extracted from ‘Atom-Ros’ has a good potential to be developed as an antioxidant agent.

Perilla frutescens (L.) is an annual herbaceous and ornamental plant in the Lamiaceae family. Perilla frutescens (L.) Britt.cv.Chookyoupjaso were irradiated using a 200 Gy gamma ray in 1995. By HPLC analysis, this new cultivar significantly induced isoegomaketone content compared with ‘Chookyoupjaso’ control. The phenotypical difference was the changed leaf color of the ‘Atom-Ketone’ from violet to green. The yield potential of this cultivar (106 kg/10a) was 1.83 folds higher than that of ‘Chookyoupjaso’ (57.65 kg/10a). The methanol extracts of ‘Atom-Ketone’ inhibit nitric oxide (NO) production in LPS-stimulated RAW 264.7 cells. This extract was further partitioned using ethyl acetate (EtOAc), butanol (BuOH), and water. The EtOAc fraction (EF-Atom-Ketone) was evaluated for antiinflammatory activities. These results indicated that the EF-Atom-Ketone reduced NO production by inhibiting inducible nitric oxide synthase (iNOS) expression. The EF-Atom-Ketone treatment also significantly diminished expression of MCP-1 and IL-6. Therefore, ‘Atom-Ketone’ reveals the potential therapeutic use of bioactive

UDP-glucose 4-epimerase (UGE) catalyzes the reversible conversion of UDP-glucose to UDP-galactose. To understand the biological function of UGE from Brassica rapa, the gene hereinafter referred to as was cloned and overexpressed into Japonica rice cv. Gopum. Transcriptional profiling showed that the is specific to stem of rice plant. Morphological evaluation of the overexpression lines revealed altered phenotype characters particularly in panicle length, number of productive tillers and filled spikelets which account for an increase in yield. This remarkable agronomic performance was ascribed to higher photosynthetic rate complemented with higher CO2 assimilation. Interestingly, BrUGE1 did not only improve plant fitness under optimal condition but also under water deficit stress. The enhanced drought tolerance may be due to the induction of soluble sugar which may act as osmolyte to compensate dehydration during drought stress.

Fatal pulmonary embolism occurs in 0.1% to 0.26% of cases of spine fusion surgery. Early diagnosis of pulmonary embolism is difficult, and delay in treatment can lead to a fatal outcome. We report on a case of symptomatic pulmonary embolism which developed after induction of general anesthesia in a patient who had been immobile because of a previous spinal operation one week prior to this. Despite a negative preoperative ultrasound examination for deep vein thrombosis, the patient had developed a pulmonary embolism, which was diagnosed using intraoperative transesophageal echocardiography. Despite intensive cardiopulmonary resuscitation and thrombolytic therapy, the patient died within a few hours of diagnosis.

We report on a unique case of diffuse large B-cell lymphoma of the cecum, which presented as a subepithelial tumor. A 62- year-old woman with abdominal pain underwent a colonoscopy, resulting in detection of a subepithelial tumor measuring 2 cm in the cecum. We performed a right hemicolectomy with diagnostic and curative intent; histological examination and immunohistochemical staining of the resected tumor indicated a diagnosis of diffuse large B-cell lymphoma. The patient achieved complete remission with combination chemotherapy.

Recently, the RNA/DNA-binding protein FUS, Fused in sarcoma, was shown to play a role in growth, differentiation, and morphogenesis in vertebrates. Because little is known about Fus, we investigated its expression pattern in murine tooth development. In situ hybridization of mouse mandibles at specific developmental stages was performed with a DIG-labeled RNA probe. During early tooth development, Fus was detected in the dental epithelium and dental mesenchyme at 11 days postcoitum (dpc) and 12 dpc. From 14 dpc, Fus was strongly expressed in the dental papilla and the cervical loop of the dental epithelium. At postnatal day 4 (PN4), Fus expression was observed in the odontoblasts, ameloblasts, the proliferation zone of the pulp, and the cervical loop. At PN14, the expression pattern of Fus was found to be maintained in the odontoblasts and the proliferation zone of the pulp. Furthermore, Fus expression was especially strong in the Hertwig’s epithelial root sheath (HERS). Therefore, this study suggests that Fus may play a role in the HERS during root development.

The detector subsystem of the Optical Wide-field Patrol (OWL) network efficiently acquires the position and time information of moving objects such as artificial satellites through its chopper system, which consists of 4 blades in front of the CCD camera. Using this system, it is possible to get more position data with the same exposure time by changing the streaks of the moving objects into many pieces with the fast rotating blades during sidereal tracking. At the same time, the time data from the rotating chopper can be acquired by the time tagger connected to the photo diode. To analyze the orbits of the targets detected in the image data of such a system, a sequential procedure of determining the positions of separated streak lines was developed that involved calculating the World Coordinate System (WCS) solution to transform the positions into equatorial coordinate systems, and finally combining the time log records from the time tagger with the transformed position data. We introduce this procedure and the preliminary results of the application of this procedure to the test observation images.

Although much effort has been made to find agronomically important loci in the soybean plant, extensive linkage disequilibrium and genome duplication have limited efficient genome-wide linkage analyses that can identify important regulatory genes. In this respect, recombination block-based analysis of cultivated plant genomes is a potential critical step for molecular breeding and target locus screening. We propose a new three-step method of detecting recombination blocks and comparative genomics of bred cultivars. It utilizes typical reshuffling features of their genomes, which have been generated by the recombination processes of breeding ancestral genomes. To begin with, mutations were detected by comparing genomes to a reference genome. Next, sequence blocks were examined for likenesses and difference with respect to the reference genome. The boundaries between the blocks were taken as recombination sites. All recombination sites found in the cultivar set were used to split the genomes, and the resulting sequence fragments were named as core recombination blocks (CRBs). Finally, the genomes were compared at the CRB level, instead of at the sequence level. In the genomes of the five Korean soybean cultivars used, the CRB-based comparative genomics method produced long and distinct CRBs that are as large as 22.9 Mb. We also demonstrated efficiency in detecting functionally useful target loci by using indel markers, each of which represents a CRB. We further showed that the CRB method is generally applicable to both monocot and dicot crops, by analyzing publicly available genomes of 31 soybeans and 23 rice accessions.

Agastache rugosa, a member of the mint family (Labiatae), is a perennial herb widely distributed in East Asian countries. It is used in traditional medicine for the treatment of cholera, vomiting, and miasma. This study assessed the genetic diversity and population structures on 65 accessions of Korean mint A. rugosa germplasm based on inter simple sequence repeat (ISSR) markers. The selected nine ISSR primers produced reproducible polymorphic banding patterns. In total, 126 bands were scored; 119 (94.4%) were polymorphic. The number of bands generated per primer varied from 7 to 18. A minimum of seven bands was generated by primer 874, while a maximum of 18 bands was generated by the primer 844. Six primers (815, 826, 835, 844, 868, and 874) generated 100% polymorphic bands. This was supported by other parameters such as total gene diversity (HT) values, which ranged from 0.112 to 0.330 with a mean of 0.218. The effective number of alleles (NE) ranged from 1.174 to 1.486 with a mean value of 1.351. Nei's genetic diversity (H) mean value was 0.218, and Shannon's information index (I) mean value was 0.343. The high values for total gene diversity, effective number of alleles, Nei's genetic diversity, and Shannon's information index indicated substantial variations within the population. Cluster analysis showed characteristic grouping, which is not in accordance with their geographical affiliation. The implications of the results of this study in developing a strategy for the conservation and breeding of A. rugosa and other medicinal plant germplasm are discussed.

Resequencing data is actively used for searching QTL or analyzing genetic diversity in the crops. However, the complexity of genome, caused by genome duplication, limits the utility of genome-wide association studies and linkage analyses to identify genes that regulate agronomically valuable traits. Here, we propose a comparative genomics approach based on core or common variation-based recombination blocks (CRB) using single nucleotide variation (SNV) density information. We found that the soybean genomes are assembled with long and distinct CRBs as large as 10Mb. CRB-based comparative genomics enabled us to accurately identify recombination blocks at the whole-chromosome level. We identified the Ih locus that determines the yellow hilum color in soybeans using CRB-based mapping with representative indel markers. These results suggest that the CRB-based comparison method is a promising platform for molecular breeding and map-based cloning.

Cereal seeds, sorghum, foxtail millet, hog millet, adlay, and corn are traditionally used as health assistant as well as energy supplying food in Korea. While beneficial phytochemicals to human have revealed in cereals, the information on peptides from cereals is far less accumulated than major reserve protein. Here, we analyzed peptide profiles using surface enhanced laser desorption/ionization time of flight mass spectrometry (SELDI-TOF MS) in cereal seeds for construction of peptide information and attempted to develop peptide biomarkers for cereal identification. To optimize the analysis condition of SELDI-TOF MS, the effect of dilution factor on binding affinity to protein chips was tested using CM10 and Q10 arrays. Peptide clusters were significantly different at the level of 0.01 p-value. Peak spectra were the most stable in 1:50 of dilution factor in both chip arrays. Numbers of detected peak of 5 cereal seeds were 131 in CM10 and 74 in Q10 array. Each cereal was grouped as a cluster and well discriminated into different cluster in the level of 0.01 p-value. Numbers of potentially identified peptide biomarkers are 11, 13, 9, 5 and 12 in sorghum, foxtail millet, hog millet, adlay and corn, respectively. This study demonstrates that each cereal seed have own distinguishable specific peptides although their function are not identified yet in this study. In addition, the proteomic profiling using SELDI-TOF MS techniques could be a useful and powerful tool to discover peptide biomarker for discrimination and assess crop species, especially under 20 kDa.

The effects of the estrogenic compound 4-nonylphenol (4-NP) on vitellogenesis in juvenile olive flounder ( ) and rockfish ( ) exposed continuously at 10, 50 and levels for 7 days were compared. The expression of VTG mRNA level and protein using specific probes were examined. The levels of plasma estradiol-17 and testosterone (T) were assessed by radioimmunoassay (RIA). Plasma concentrations increased significantly in two female fish species exposed to of 4-NP over concentrations in control fish. Plasma T concentrations increased in . Four days after exposure, the level of VTG mRNA expression increased in and exposed to of 4-NP. In addition, plasma VTG protein expression was seen in and . In and exposed to 4-NP, the changes were noticed mainly in hepatocytic vaculation after 7 days of exposure. Thus, 4-NP may disrupt vitellogenesis in immature fish both directly and indirectly via disrupted steroidogenesis and liver pathology. Immature were the most sensitive to 4-NP exposure in vitellogenesis.
