A study was conducted to determine the susceptibility of swine to Korean foot-and-mouth disease virus (FMDV; subtype O, isolated from Chungju province) in April, 2ooo. One holstein cow was inoculated intradermolingually with suspension of homogenized tissue from a Korean native cow naturally infected with Korean FMDY. Infected cow was housed with one susceptible cow and one susceptible pig (contact sentinels). Four additional susceptible pigs were housed in the same room but caged separately (non-contacted sentinels). The contacted pig and cow as well as non-contact pigs developed typical clinical signs after 2, 3, and 7 days post exposure, respectively. We compared neutralizing antibody from the animals to FMDV $O_1$ Lombardy, O Taiwan, $O_1$ Campos, and $O_1$ Manisa after 0, 4, 7, 10, 14, 21, 28 days post challenge and post-exposure. The highest viral neutralization titer could be interpreted that serotype O Korea (Chungju isolate) is antigenically more related to $O_1$ Manisa. In addition, immunohistochemistry was used to further characterize Korean FMDV from tissues of infected pigs. Korean FMDV antigen was observed in the tongue, hoof, esophagus, and tonsil tissues of sentinel pigs. These findings suggest that Korean FMD virus isolated from cattle can be rapidly transmitted to pigs both directly and indirectly contrast field observation in which only cattle were clinically ill.

How far can African swine fever spread?

서정향 대한수의학회 2019 Journal of Veterinary Science Vol.20 No.4

African Swine Fever (ASF) is a highly contagious and deadly viral disease affecting both domestic pig and wild boar populations. Once introduced, it is a terrible disease that can devastate the swine industry in many countries. ASF has spread most recently beyond China to Southeast Asia, and parts of the Korean Peninsula. The majority of Asian countries consume pork as the primary source of meat compared to all other meat products. Particular emphasis is on the spread of ASF within North Korea and on future perspectives including protective guidelines. Thus far, the Korean peninsula has endured an extensive history of diseases, most notably from foot and mouth disease. For this reason, the Korean swine industries are familiar with the detrimental impacts of such a disease. On the other hand, exposure to a disease like ASF will decimate the swine industry even further. Therefore, it is crucial to bring urgent awareness to the spread of ASF.

Listeria monocytogenes antigens were detected with the avidinbiotinperoxidase complex(ABPC) method in formalin-fixed, paraffin-embedded tissues from experimentally infected rats, mice and guinea pigs. The anti-Lirteria monocytogenes serum used as first antibody was prepared by immunizing rabbits with Listeria monocytogenes serotype 1/2a. Rats, mice and guinea pigs that had been given inoculation of L monocytogenes(serotype 4b, Scott A strain) via intraperitoneally allotted to 3 groups. Rats were pretreated with the dexamethasone(DM-rats) for 7 consecutive days, mice and guinea pigs were inoculated intraperitoneally with L. monocytogenes At necropsy white necrotic foci of the liver, spleen and kidney were seen in mice and DM-rats, whereas not in guinea pigs. Organisms stained by the ABPC method were identified as pleomorphic dark brown staining structures in the livers, spleens and kidneys of mice and DM-rats. They were present in high numbers in center and peripherial regions of necrobiotic and necrotic foci of the liver and spleen as well as in glomerulus of the renal cortex. and liable tool for confirmative diagnosis of these bacterial diseases.

Tofu and soybean sprouts are principle food consumed in Korea, and recent demand for them has increased because of renewed interest in functional foods. From 2006 to 2011, tofu sales have increased from 342.4 billion won to 498.9 billion won, and packaged tofu sales is estimated to be occupied more than 65% of that sales, Also soybean sprout market size as packaged product is increasing. The increase of packaged tofu and sproul sales may be caused by many factors related to economic growth, social change, and rapid advancement of food processing industries. This paper review the case of commercialized tofu and sprout using domestic soybeans. Packaged tofu and sprout production companies prefer using domestic soybean, and Consumers are recognized as high quality of tofu and sprout made from domestic soybeans.

Primary Renal Hemangiosarcoma Complicated with Hematuria and Hemoperitoneum in a Dog

여정진,서정향,엄기동,박희명 한국임상수의학회 2012 한국임상수의학회지 Vol.29 No.2

A 14-year-old intact male Siberian Husky was presented with hematuria, lethargy, and anorexia of 1-month duration. The physical examination revealed mild abdominal distension and pain. The hematology and serum chemistry revealed anemia and severe azotemia. The radiographic examination revealed renomegaly and the ultrasonographic examination, indistinct cortico-medullary junction, increased renal cortex echogenicity, and irregular margination. The urinalysis showed proteinuria and hematuria. The differential diagnosis included renal failure, cystitis, pyelonephritis,and neoplasia. The patient's condition continued to deteriorate, and the dog eventually died. The gross findings from the necropsy revealed hemoperitoneum and a bilateral renal mass. HSA was diagnosed by histopathological examination. This case report describes primary bilateral renal hemangiosarcoma (HSA), which is uncommon in dogs.

Therapeutic Effect of Cyclosporine Administration in a Dog with Pemphigus Foliaceus

김정현,서정향,박철,김하정,박희명,유종현 한국임상수의학회 2009 한국임상수의학회지 Vol.26 No.4

A 3-year-old, intact female Poong-san dog was presented with a 4-month history of erosive, erythematous dermatitis unresponsive to systemic antibiotics and glucocorticoids. Crust, erosion, and alopecia were noted on the ear pinnae, bridge of nose, and forelimb. Cytological evaluation of intact pustules showed isolated free-floating rounded acantholytic keratinocytes admixed with non-degenerated neutrophils and eosinophils. Results of histopathologic examination revealed the intra-epidermal pustules with predominant neutrophils, less eosinophils, and isolated and clustered acantholytic cells. A diagnosis of pemphigus foliaceus (PF) was made based on the history, clinical, cytological and histopathological results. The skin lesions had improved after systemic cyclosporine therapy. This case report demonstrates that cyclosporine, an immunosuppressive agent, can be used in the management of PF in dogs.

This research initiated a contemplation of the criteria to analyze the growth of low-income students, conceptualizing various forms of educational growth within and beyond the standards of career achievement as “decent life,” and exploring the factors and characteristics of “decent life” perceived and expected by low-income youth. For this purpose, a qualitative longitudinal study was conducted by S Foundation, with young adult participants born in 1994, 1997, and 2000. The analysis was primarily based on interview data from 2022, with a focus on questions related to “decent life.” As a result, “decent life” perceived by low-income youth encompassed the following dimensions: 1) life with economic stability, 2) life with work and a balance between work and life, 3) life with stable relationships, 4) discovery of one`s own identity and a satisfying life, 5) life of continuous personal growth, and 6) life that practices social values. The research findings provide an opportunity for reflection on the goals and roles of education for the educational growth of low-income students. This study offers educational implications that suggest the need to explore ways to help research participants to discover and achieve their desired “decent life,” even under adverse conditions. 이 연구는 저소득층 개인의 성장을 분석할 때 무엇을 성장의 기준으로 삼을 것인가에 대한 문제의식에서 출발하여, 진로 영역에서의 성취 기준 안팎에 존재하는 다양한 교육적 성장의 모습을 ‘괜찮은 삶’으로 개념화하고, 저소득층 청년들이 인식하고 기대하는 ‘괜찮은 삶’의 요인과 특성, 의미를 탐색한 질적 사례연구이다. 이를 위해 S장학재단 질적 종단연구의 연구참여자 1994년생, 1997년생, 2000년생 청년들을 연구참여자로 선정하였고, ‘괜찮은 삶’에 대한 질문에 초점을 둔 2022년도에 면담자료를 중심으로 분석하였다. 그 결과 저소득층 청년들이 인식하는 ‘괜찮은 삶’은 1) 경제적으로 안정된 삶, 2)일과 워라밸이 있는 삶, 3) 관계의 안정이 있는 삶, 4) 나다움을 발견하고 만족할 수 있는 삶, 5) 성장을 지속하는 삶, 6) 사회적 가치를 실천하는 삶으로 나타났다. 연구결과는 저소득층 학생들의 교육적 성장을 위한 교육의 목표와 역할에 대해 성찰하는 기회를 제공하며, 저소득층 학생들이 불리한 여건에서도 저마다 지향하는 ‘괜찮은 삶’을 성취할 수 있도록 지원하는 방안을 모색해야 한다는 교육적 함의를 제공한다.
