  • The aim of this survey was to investigate the characteristics of outbreak farm determined as the classical swine fever(CSF) at Gangwha-gun and Seo-gu, Incheon metropolitan area from October 7 to November 25 in 2002. Sixty pigs in six different farms were confirmed to the CSF and a total of 9,106 pigs containing 3,194 related epidemiologically was slaughtered to stop spreading of the disease. Clinical signs of pigs diagnosed with the CSF were high fever, anorexia, depression, paralysis of hindlimbs, cyanosis, etc and gross lesions were typically represented with hemorrhage of submandibular and superficial lymph node, infarction of spleen, and petechial (ecchymotic) hemorrhage of kidney and skin. But some outbreak farms had not shown remarkable symptoms, so they were confused with other bacterial diseases. White blood cell (WBC) counts, the classical swine fever virus(CSFV) antigen and antibody enzyme linked immunosorbent assay(ELISA) and reverse transcriptase polymerase chain reaction (RT-PCR) results about six farms indicated that total 60 pigs were infected with the CSFV. Although the origin and infection route of the CSFV were not clear, but the transmissions between farms were mainly through indirect contact such as the movement of farm personal and vehicles from outbreak farm.

  • Purpose : Fever, the most common presenting symptom in pediatric clinics, has been believed to be a dangerous symptom by many parents. Proper recognition about fever will relieve unnecessary anxiety of parents and help them understand the course of the disease. Our objectives of this study were to investigate current parental recognition about fever and to compare these results with those described in 1992. Methods : Between May and July 2006, we questioned caregivers who visited the pediatric outpatient clinic in St.Paul hospital. The questionnaire consisted of 19 items asking about recognition, attitude and management of fever. Results : A total of 136 caregivers were interviewed. Compared with 10 years ago, there were no significant improvements in misconception about fever. Many caregivers (61%) had wrong information about a definition and the way to measure body temperature. There were still high concerns about febrile convulsion and brain damage from fever. Caregivers started treatment at the body temperature which actually needed no therapy. Conclusion : Parents were not aware that fever is just one of physiologic responses and has benefits, which led to unnecessary anxiety and treatment. This misconception has not been changed over the years. Pediatrician should inform parents that fever itself is not harmful and only rational reason for use of antipyretics is to relieve a discomfort of a febrile child. An educational interventions offered by pediatricians will be helpful for parents to have right attitude and understandings toward fever.

  • This study regarded irregular life styles such as nigh-shifts as contrary to the norm advised in the rules of Yang-saeng to analyze the problems brought about in relation to the concept of 'Yin-deficiency syndrome'. Yin-deficiency survey was given to sales workers on a big shopping mall in Seoul to compare the measurements of daytime workers to those of nigh-shift workers. The measurement of complaining symptoms related to Yin-deficiency of daytime workers and night-shift workers were compared, In comparison of the daytime workers and the night-shift workers, night-shift workers showed higher measurements than the daytime workers in the item of irritable fever on the five Hearts, flushing of the zygomatic region in the afternoon, tidal fever, dizziness, insomnia, yellow and scanty urination, and constipation. Especially tidal fever, insomnia, and constipation showed statistically significant difference. The total of ten items consisting of Yin-deficiency-related symptoms showed statistically significant high score in night-shift workers than the daytime workers. 'Factors for deficiency-type Heat' consisting of irritable fever on the five Hearts, flushing of the zygomatic region in the afternoon, tidal fever, and dried mouth and throat showed statistically significant high score in night-shift workers than the daytime workers. 'Accompanying factors' consisting of night sweats, emaciation, dizziness, insomnia, yellowish and scanty urination, and constipation also showed statistically and significantly high score in night-shift workers than the daytime workers. From the above results that night-shift workers show high degree of Yin-deficiency than daytime workers, and those overworking irregularly also show high degree of Yin-deficiency than those who work for adequate amount of time regularly implies that sitting up at night for work and sleeping at daytime, excessive work, and irregular life styles all function as high-risk factor for Yin-deficiency.

  • This study intended to grasp the results of performance of school health policy and to provide information for the future policy performance in Korea. As the objects of the study we chose the secondary school(142 middle schools, 111 high schools) in Pusan, 1993. The contents of the study were about school health service and school health education. For the study we collected datum and took statistics through the existing theses, books, various statistics, and interviews with the persons concerned. Therefore the method of the study was basically emperical and demonstrative. The results of the study can be presented as follows : 1. the results of performance of health service proved to be 5.40% for vaccination against hepatitis B, 5.26% for typhoid fever, 6.65% for EH fever, and 9.84% for influenza in middle schools, In high schools' 5.76% for vaccination against hepatitis B, 0.03% for typhoid fever, 0.25 for EH fever, and 0.86% for influenza. 2. The results of policy performance of health education were found out 64.08% in middle schools, and 17.12% in high schools. 3. The factors which affected the results of performance of health service turned out 1) the improper standard of policy performace that applicants should pay their own expenses. 2) the lack of performer's will to carry out the policy owing to the improper standard. 3) the shortage of interorganizational enforcement activities and communications which influence the will of performance. 4. The affecting factors to the will of performance of health education proved to be 1) the improper standard that nurse-teachers can teach students in the classroom in case of need. 2) the lack of nurse-teachers due to the above inappropriate standard. 3) the lack of enforcement activities of supervising organs which employ and direct nurse-teachers. 4) the lack of activities of organs which should communicate one another and allot nurse-teachers of public schools without fail.

  • Background: In South Korea, African swine fever virus (ASFV) has spread among wild boars through Gangwon-do to Dangyang-gun, Chungcheongbuk-do on the southern border of Gangwon-do. To prevent the spread of ASFV to African swine fever (ASF)-free areas, it is necessary to identify areas with a high probability of finding ASFV-infected carcasses and to reduce the density of wild boars in those areas. In this study, we described the propagation trend of ASFV among wild boars, constructed the habitat suitability maps for ASFV-infected carcasses, and suggested areas with a high probability of finding ASFV-infected carcasses and an important route of ASFV transmission. Results: Despite the active quarantine policies in Korea to prevent the spread of ASFV through wild boars, there was no significant difference in the monthly average of number of ASFV-infected carcasses observed between 2020 and 2021. The ASFV-infected carcasses were found more in winter and spring (January to April). Since the first ASF outbreak in wild boars on October 2, 2019, the maximum width of ASFV-infected carcass distribution area was 222.7 km for about 26 months till November 20, 2021. The habitat suitability map, based on GPS coordinates of ASFV-infected wild boar carcasses, shows that highly detectable areas of ASFV-infected carcasses were sporadically dispersed in western and southwestern parts of Gangwon-do, and ranged from north to south of the province along the Baekdudaegan Mountains, whereas poorly detectable areas ranged along the north to the south in the middle parts of the province. Conclusions: Our suitability model, based on the GPS coordinates of ASFV-infected carcasses, identifies potential habitats where ASFV-infected carcasses are likely to be found and ponential routes where ASFV is likely to spread. Among ASF-free areas, the areas with high suitability predicted in this study should be given priority as survey areas to find ASFV-infected carcasses and hunting areas to reduce wild boar populations.

  • Classical swine fever virus (CSFV) is the etiologic agent of classical swine fever, a highly contagious disease that causes significant economic losses to the swine industry. The lapinized C-strain, a widely used vaccine strain against CSFV, has low growth efficiency in cell culture, which limits the productivity in the vaccine industry. In this study, a recombinant virus derived from C-strain was constructed and subjected to continuous passaging in PK-15 cells with the goal of acquiring a high progeny virus yield. A cell-adapted virus variant, RecCpp80, had nearly 1,000-fold higher titer than its parent C-strain but lost the ability to induce fever in rabbits. Sequence analysis of cell-adapted RecC variants indicated that at least six nucleotide changes were fixed in RecCpp80. Further adaption of RecCpp80 variant in swine testicle cells led to a higher virus yield without additional mutations. Introduction of each of these residues into the wild-type RecC backbone showed that one mutation, M979R (T3310G), located in the C-terminal region of E2 might be closely related to the cell-adapted phenotype. Rabbit inoculation revealed that $RecCpp40_{+10}$ failed to induce fever in rabbits, whereas $RecCpp80_{+10}$ caused a fever response similar to the commercial C-strain vaccine. In conclusion, the C-strain can be adapted to cell culture by introducing specific mutations in its E2 protein. The mutations in RecCpp80 that led to the loss of fever response in rabbits require further investigation. Continuous passaging of the C-strain-based recombinant viruses in PK-15 cells could enhance its in vitro adaption. The non-synonymous mutations at 3310 and 3531 might play major roles in the enhanced capacity of general virus reproduction. Such findings may help design a modified C-strain for improved productivity of commercial vaccines at reduced production cost.

  • Nine dogs with history of lameness and anorexia were presented. On physical examination, all dogs had gait abnormality and six dogs had high body temperature. Their clinical signs were mostly episodic, and only non-specific symptoms were occasionally observed. Arthrocentesis was performed in all dogs, and immune-mediated polyarthritis (IMPA) was diagnosed. Definitive rheumatoid arthritis (RA) and systemic lupus erythematous (SLE) were diagnosed in one dogs, one each. Prednisolone (PDS) was chosen as the first-line therapy for all dogs, except for the one with RA. Most cases responded to PDS but some cases including those of SLE and RA were refractory to PDS. IMPA can be challenging to diagnose due to its vague symptom and is commonly implicated in 'fever of unknown origin'. Therefore, clinicians should consider IMPA as a differential diagnosis when the patient has fever with systemic, non-specific signs, such as anorexia and depression, but does not respond to antibiotics.

  • This study was carried out to investigate the analgesic and antipyretic effects of acupuncture in goat suffered from pain and fever induced experimentally : electroacupuncture and laser acupuncture for the relief of pain and traditional needing for the of fever. Pain was induced by intraperitoneal injection of 0.7% acetic acid solution and it's extent was estimated with the number of writhing syndrom as indicator of pain. When lipopolysaccharide was given into the vein in goat, fever with biphasic type was produced. In the goats with pain the superior analgesic effects of electroacupuncture to aminopyrine and sulpyrine were found, but the effects of laser acupuncture were not satisfactory. The high body temperature of goats was gradually decreased with the lapse of time following traditional needling(venesection by needle) and showed a tendency to return to normal body temperature. Serum GOT, GPT:, BUN, creatinine values and acetylcholinesterase activity following electroacupuncture were not altered. It is considered that electroacupuncture combined with medicament can sucure exellent analgesic and antipyretic effects in animal practice.

  • A protein chip based on surface plasmon resonance (SPR) imaging was developed for measuring classical swine fever virus (CSFV) antibody using a recombinant gp55 protein as an antigen. The diagnostic potential of SPR imaging for detecting antibodies to the CSFV gp55 protein was compared with that of a enzyme -linked immunosorbent assay (ELISA) using 70 pig sera. There was a strong positive correlation between the SPR imaging and ELISA (n=70, r=0.916, p<0.01). Therefore, the SPR imaging, which is a label-free and high-through put method, is expected to be a valuable tool in the serodiagnosis of CSFV.
