  • Foot-and-mouth disease virus (FMDV) belongs to the aphthovirus genus within the picornavirus which has a single copy of a positive sense RNA. The translation initiation process of FMDV occurs by a cap-independent mechanism directed by a highly structured element (∼435 nt) termed an internal ribosome entry site (IRES). We have designed and prepared FMDV 4-2 RNA (28nt) by in vitro transcription. The 2D NMR data revealed that FMDV 4-2 IRES domain RNA has a flexible loop and bulge conformation. In further study, we need to make an isotope labeled RNA sample and conduct 3D NMR experiments to completely determine the 3D structure. This study may establish a new drug design strategy to treat foot-and mouth disease.

  • A bacterial disease of elephant foot, Hydrosome rivieri Engl., was newly found in Taejon, Korea in August 1986. The affected plants showed symptoms of soft rot on leaf blades and petioles. Bacterial isolates from affected plants found to be pathogenic to elephant foots by antificial inoculation, producing similar symptoms with those produced naturally. The baterium was also pathogenic to carrot, Chinese cabbage, radish, potato and onion, and developed symptom of soft root on them. On the basis of bacteriological characteristics and pathogenicity, tested bacterium was identified as Erwinia carotovora subsp. carotovora and this disease was proposed to name 'Bacterial soft rot of elephant foot'.

  • Foot and mouth disease (FMD) is a highly contagions disease of cloven-hoofed animals and occurs in many non-European countries, in particular in huge parts of Asia including Turkey, in most countries of Africa and in parts of South America. The extreme contagiousness of the disease requires comprehensive to control an outbreak, causing high economic losses. The outbreak of FMD, which affects livestock including cattle, swine,sheep,goats,deer and other animals as a highly communicable disease that affects. The agency issued a statement noting that FMD disease does not spread to humans. The disease and meat from infected animals are news reports that more than 3.400.000 livestock have been ordered slaughtered so far across the country.

  • Asia1/Shamir that has been recommended by World Reference Laboratory for foot-and-mouth disease (FMD) is used as a vaccine strain, and is being prepared in many countries including Korea. Although it is assumed that vaccine strain Asia1/Shamir has a wide antigenicity, sufficient molecular biological analysis has not been accomplished yet. Complete genome sequence analysis showed that the region with the most severe variations was 1D region of structural protein-coding sequence; particularly amino acid 141~157 residues in 1D region RGD sites for binding to susceptible cells. In addition, five amino acids in 1D region were identified as characteristic sites that are different from other known Asia1 viruses. Asia1/Shamir strain was shown to be genetically similar to group VI that had occurred in the Middle East, but showed low level of genetic similarity to the group V viruses that had occurred in the Southeast Asia and China. It is considered that, if these viruses, group I and II including group V are introduced into Korea, care would be paid in case of inoculating the vaccine strain Shamir available in Korea.

  • Foot-and-mouth disease (FMD) virus exists in seven serotypes and is known to be a highly contagious disease that is hard to eradicate from the world. The O, A, Asia1 and SAT2 serotypes commonly infected cattle, sheep and goats during 2007~2009 throughout the world. In particular, the outbreak of the Asia1 serotype in China appeared in all areas from 2005 and is still present. Surprisingly, in 2009, Taiwan reported the first outbreak of the type O serotype since 2001. Then type A appeared in China for the first time since the early 1960s. The virus shows a close relationship to the viruses from Southeast Asia suggesting one or more recent introductions into China in the OIE reports. Recently the subtype of A/Iran05 spread to nearby countries exhibiting genomic evolution. The use of molecular epidemiology is an important tool in understanding and consequently controlling the FMD virus. The phylogenetic analysis with VP1 gene was especially useful for molecular epidemiological studies and showed the same pattern which matches with serotype classification. This paper describes basic information about the disease, and the serotype-specific characteristics and evolution to perform molecular epidemiological analysis. Furthermore, we show the importance of the genetic evolution on the FMD serotypes in global surveillance and molecular epidemiology of FMD for outbreak investigation.

  • With comparison of maximum vertical reaction force and lower limb on drop landing between normal and flat foot group, this study is to provide fundamental data of the prevention of injury and the treatment of exercise which are frequently occurred on flat foot group's drop landing. The surface electrodes were sticked on lateral gastrocnemius muscle, medial gastrocnemius muscle, tibialis anterior and the drop landing on a force plate of 40cm was performed with a normal group who had no musculoskeletal disease and a flat foot group of 9 people who had feet examinations. Vertical reaction force were significantly statistically different between two groups(p<.001). Muscle activity of lower limbs in all three parts were not statistically different but showed high tendency on average in the flat foot group. The flat foot group had difficulties in diversification of impact burden and high muscle activity. Therefore, it was suggested that muscular strengthening of knee joints and plantar flexions of foot joints which were highly affected in impact absorption will be required.

  • Purpose: This study was performed to analyze the trend of foot reflexology research in nursing in Korea. Method: Of studies published in nursing literature between January 1990 and August 2007. The 74 articles were analyzed according to the published year and journal, type of research and study design, subject, and the outcome variables of interventions. Result: Prevailing research designs were experimental research (nonequivalent control group pretest-posttest design). Prevailing characteristics of subjects were patients with hypertension, diabetes mellitus, hemodialysis, cancer and others disease (osteoarthritis, cerebral vascular accident, pneumoconiosis). The most frequently performed intervention was Foot-Reflexo-Massage (FRM). The most frequently used outcome variables were fatigue and sleep. The effect of foot reflexology was inconclusive. Conclusion: The finding suggests that a robust research design in foot reflexology research is needed to accumulate a strong scientific evidence and to adopt nursing intervention from the foot reflexology modalities. Meta analysis of foot reflexology research should be done to analyze and integrate the results of various studies.

  • Background: A diabetic foot is the most common cause of non-traumatic lower extremity amputations (LEA). The study seeks to assess the risk factors of amputation in patients with diabetic foot ulcers (DFU). Methods: The study was conducted on 351 patients with DFUs from January 2010 to December 2018. Their demographic characteristics, disease history, laboratory data, ankle-brachial index, Wagner classification, osteomyelitis, sarcopenia index, and ulcer sizes were considered as variables to predict outcome. A chi-square test and multivariate logistic regression analysis were performed to test the relationship of the data gathered. Additionally, the subjects were divided into two groups based on their amputation surgery. Results: Out of the 351 subjects, 170 required LEA. The mean age of the subjects was 61 years and the mean duration of diabetes was 15 years; there was no significant difference between the two groups in terms of these averages. Osteomyelitis (hazard ratio [HR], 6.164; 95% confidence interval [CI], 3.561-10.671), lesion on percutaneous transluminal angioplasty (HR, 2.494; 95% CI, 1.087-5.721), estimated glomerular filtration rate (eGFR; HR, 0.99; 95% CI, 0.981-0.999), ulcer size (HR, 1.247; 95% CI, 1.107-1.405), and forefoot ulcer location (HR, 2.475; 95% CI, 0.224-0.73) were associated with risk of amputation. Conclusion: Osteomyelitis, peripheral artery disease, chronic kidney disease, ulcer size, and forefoot ulcer location were risk factors for amputation in diabetic foot patients. Further investigation would contribute to the establishment of a diabetic foot risk stratification system for Koreans, allowing for optimal individualized treatment.

  • Purpose: The authors evaluated the clinical results and prognosis after amputating the lower extremity due to diabetic foot. Materials and Methods: From 1991 to 2003, the patients who had suffered amputation of his lower extremity due to diabetic foot ulcer were evaluated retrospectively. 79 patients were male and 6 patients were female. The author evaluated the patient who had the ipsilateral additional surgery, contralateral amputation, level of blood sugar, combined disease and mortality rate within 5 years from medical record. Statistical analysis was done by Chi-square test and Kaplan-Meier survival test. Results: Mean age of patients who had first experienced amputation was 63.4 years old. The mean duration of diabetes until amputation was $14.5{\pm}7.5$ years. Major amputations were 50 cases and minor amputations 35 cases. 20 patients (23.5%) were suffered ipsilateral secondary surgery including revised stump. Overall 5-year mortality rate was 18.8% (16 cases). Death rate within 1 year was 8.2% (7 cases), mortality rate within 3 years was 14.1% (12 cases). 5-year mortality rate after major amputation was 20% (10 cases) and after minor amputation was 17.1% (6 cases). It was statistically significant (p<0.05). Patient who underwent more than 2 combined vascular related disease had higher mortality rate than diabetic amputee without combined disease (p<0.05). Conclusion: Mortality rate after major amputation was significant higher than amputation after minor amputation in diabetic patients from our data.
