  • The prospect of live vaccines consisting of genetically modified vaccinia virus expressing foreign genes is exciting, but important issues concerning safety and efficacy need to resolved. Vaccinia virus (VV) is an efficient expression vector with broad host range infectivity and large DNA capacity. This vector has been particularly useful for identifying target antigens for humoral and cell-mediated immunity. The WHO smallpox eradication program, involving the extensive use of VV vaccines, resulted in the late 1970s in the elimination of one of the world's most feared diseases. This achievement is a triumph for preventive medicine and for international collaboration in public health. In 1980, WHO recommended that the routine use of smallpox vaccine should be stopped. Against this background, the prospect of li ve vaccines consisting of genetically modified VV expressing foreign antigens arising from the work of Moss, and Paoletti and their colleagues in 1982 has been greeted with enthusiasm. These investigators have shown that genes coding for immunogenic proteins can be inserted into VV DNA without impairing the ability of the virus to grow in cell culture. Moreover experimental animals infected with VV recombinants containing genes coding for a variety of immunizing proteins have been shown to be protected against challenge infection with the corresponding infectious agent. In this communication, I describe current progress in the construction of a novel plasmid vector that facilitate the insertion and expression of foreign genes in VV as well as the selection of recombinants.

  • In order to investigate the safety of Aralia elata extract causing the reduction in the blood glucose level and oxidative stress in diabetes animals, these genotoxicity studies in bacterial and mammalian cell assay system such as Ames bacterial reverse mutation test and chromosomal aberration assay were performed. As results, in Ames bacterial reversion assay the extract in the range of 5,000-625 ug/plate did not induce mutagenicity in Salmonella typhimurium TA 98, TA 100, TA 1535 and TA 1537 strains with and without metabolic activation of S-9 mixture. For chromosomal aberration assay, $IC_{50}$ (50% inhibition concentration of cell growth) of the extract were determined; 792 $\mu\textrm{g}$/$m\ell$ without and 524 $\mu\textrm{g}$/$m\ell$ with S-9 mixture in Chinese hamster lung (CHL) fibroblast cell culture. Any significant chromosomal aberration was not observed in CHL cells treated with the extract at the concentrations of 792, 396 and 198 $\mu\textrm{g}$/$m\ell$ or 524, 262 and 131 $\mu\textrm{g}$/$m\ell$ in the absence or presence of S-9 metabolic activation, respectively. From these results, Aralia elata extract did not induce any harmful effects on the gene in bacteria and mammalian cell system used in these experiments.

  • Molecular farming is production of pharmaceutically and industrially important proteins in plants. Plants and plant cell culture systems have been used as bio-factory to produce recombinant proteins such as monoclonal antibodies, enzymes, vaccines, hormones, interleukins, commercial enzymes and etc. The terms molecular farming, biofarming, molecular pharming, phytomanufacturing, recombinant or plant-made industrials, planta-pharma, plant bioreactors, plant biofactory, and pharmaceutical gardening are used interchangeably. Molecular farming can provide safe and inexpensive pharmaceutical proteins as well as commercial ones. In spite of several advantages of molecular farming such as safety and inexpensive cost, there are also a couple of drawbacks in the existing technology. One of them is low expression level of target gene in plants, which has been improved by optimizing gene-based codon usage, screening of strong promoters, expression of transcription factors, subcellular targeting of target proteins, chloroplast transformation, and transient expression using viral expression system (magnifection). Some plant-based commercial proteins have already been in markets and more than twenty plant-based pharmaceuticals have been in clinical trials, from that we can expect that several plant-based pharmaceutical proteins will be seen in the markets in the near future.

  • Biogenic amines in some food products present considerable toxicological risks as potential human carcinogens when consumed in excess concentrations. In this study, we investigated the degradation of the biogenic amines histamine and tyramine and the presence of genes encoding histidine and tyrosine decarboxylases and amine oxidase in Bacillus species isolated from fermented soybean food. No expression of histidine and tyrosine decarboxylase genes (hdc and tydc) were detected in the Bacillus species isolated (B. subtilis HJ0-6, B. subtilis D'J53-4, and B. idriensis RD13-10), although substantial levels of amine oxidase gene (yobN) expression were observed. We also found that the three selected strains, as non-biogenic amineproducing bacteria, were significantly able to degrade the biogenic amines histamine and tyramine. These results indicated that the selected Bacillus species could be used as a starter culture for the control of biogenic amine accumulation and degradation in food. Our study findings also provided the basis for the development of potential biological control agents against these biogenic amines for use in the food preservation and food safety sectors.

  • This study investigated the public use of Myeon Location in Jeollanam - do where the population is at risk of declining. And discussed the rational provision and coordination of public facilities as a guarantee of fundamental rights. As a result of the study, the rational supply and adjustment directions of public facilities are as follows. First, there are problems such as high availability of management, finance, shopping, and health facilities, lack of culture, leisure, community facilities, and weakening of center function. Therefore, in the continuing declining population situation, face management, safety and health facilities should be upgraded to multifunctional facilities, and utilization efficiency and integration should be promoted. In addition, town center rehabilitation should be centered on multifunctional facilities. In addition, elementary schools will have to utilize and preserve them to take advantage of local cultural values as nostalgia storing place that provide incentives for young people and elementary school children in the future. Second, in order to cope with population decline, public facilities need to strengthen public services through complexity and multifunctionality, wide-area operation with neighboring areas, and user-centered operation management.

  • Nor-aporphine derivatives have been discovered which interfere with the flux of Calcium into and out of the cell interior. It has been shown that adrenergic antagonists that block the Calcium exchange lead to an inhibition of Protein kinase C activity, thus blocking tyrosinase activation. Di-acetyl-dimethoxy-methyl-nor-aporphine is a semi-synthetic molecule of natural origin with very high potency. On B16 melanocytes as well as in normal human melanocytes the decrease in melanin synthesis reaches -50% at a level of 40 ppm in the culture medium. On a molar concentration basis, this is 50 to 70 times stronger than Kojic acid inhibition. Yet, the cell viability is not affected. Reversibility studies show that after washing out of the active compound, melanogenesis returns to normal levels. Possible mechanisms of the activity are discussed. Tests carried out on SkinEthic(R) three-dimensional models of the epidermis and in vivo clinical studies on Asian population confirm the strong inhibition of melanogenesis. Safety evaluation of these molecules, on the other hand, demonstrates good skin tolerance and absence of toxicity.

  • The dog breeding kennel bacterial infection are very significant in perinatal mortality. In many case, Staphylococcus aureus, Streptococcus, and Escherichia coli were infected in intra-uterine or by the genital tract to the puppies, and they are cause of septicemic death of the puppies and clinical mastitis of bitch, leading to septicemic death of newborn puppies. Severe mastitis due to bacterial infection was diagnosed in a 2 year-old female Brittany Spaniel which loss 6 puppies with odor small rice sharp white diarrhea of nine puppies. Bright curd milk and intestinal sample were inoculated on MacConkey agar, blood agar and brain heart infusion agar, and incubated at $37^{\circ}C$ for 24-48 hrs. Gram negative colonies isolated from these sample which were characterized as Glu, Ure, $H_2S$, Orn, Cit, and Cl, and were identified by Microscan Walk-Aways Baxter, American Type Culture Collection, USA) as Proteus mirabils. The isolate was more sensitive to ampicillin, gentamicin, cefoxitin, cefuroxime, and cefazidime. In this results, we confirmed that cause bacteria of septicemic death in puppies was P. mirabilis.

  • Objectives: The purpose of this study was to explore coordination strategy through reviewing policies, action plans and acts related to diet, nutrition and obesity from many sectors in Korea, and to develop a possible multi-sectoral approach. Methods: Literature reviews and empirical findings for ongoing international and domestic policies/programs on diet, nutrition and obesity in Korea. Results: Central and local governments have various policies/programs and related acts to improve nutrition and to reduce obesity. Meanwhile, those governments' activities are frequently criticized to be more coordinated in order to achieve their aims. Activities on nutrition and obesity prevention have interdepartmental characteristics but are scattered through six Ministries (including the Ministry of Health and Welfare, Ministry of Education, Ministry of Agriculture, Ministry of Employment and Labor, Ministry of Culture and Sports, and Ministry of Food/Drug Safety) and 27 Acts such as 'Nutrition Management Act', 'Health Promotion Act', 'Diet Education Support Act'. As a result, a number of areas, especially dietary guidance, nationwide surveys, education programs seem to overlap. Conclusions: Inter-ministerial coordination mechanism should be established to enforce multi-sectoral engagement and cooperation in implementing policies/programs on nutrition and obesity prevention. Furthermore, functions of the Ministries should be reorganized and coordinated in reference to other countries' experiences.
