In order to provide fundamental data of food circulation policy, we performed monitoring the safety of the imported food which was circulating through Gwangju from March to October, 2005. Acid and peroxide value which are barometers for evaluation of the quality of lipid were investigated in 130 samples of imported oil treatment food. Not-permitted tar pigment and artificial sweetner were investigated in 139 candies by TLC and HPLC. The content of sulfur dioxide in 129 samples of dried fishery products and dried fruits was investigated by Monier-Williams method. In 130 samples of imported oil treatment food, 9 samples (6.9%) were incongruent with acid value, 6 samples (4.6%) with peroxide value and 4 samples (3.1%) with acid value simultaneously with peroxide value. In 139 imported candies, not-permitted artificial sweetner were found in 2 samples (1.4%). In 129 samples in which sulfur oxide was analyzed,4 samples (3.1%) were incongruent. Finally, in total 398 samples in which this study was analyzed, 25 samples (6.3%) were incongruent.

This study was conducted to investigate students' food consumption including potentially hazardous food (PHF) and food preference in elementary school lunch menus. High protein foods and raw or cooked vegetable dishes in the menus for three weeks were grouped as PHF-1 and PHF-2, respectively. Three hundred eight-four children from three different elementary schools, aged 10 to 12 years, completed the questionnaire that asked them to report on how much they eat, what foods they like the most and the least, and why they did not like it. Chisquare test was used to analyze the differences among schools, Evades and genders far food consumption using the SPSS. Results showed that students were exposed to at least two kinds of PHF in school lunches per day. 89% and 82% of students ate 100% amount of PHF-1 and PHF-2, respectively. There were significant differences in the amount of food consumption by school and day served. Students preferred high protein foods, such as meat ball, pork and chicken barbecues, which were consumed the most. These data indicate that appropriate control measures or procedure is needed to manage hazards associated with PHF in the menu items to decrease the risk of foodborne illness in school lunch.
Growth Inhibitory Activity of Sulfur Compounds of Garlic against Pathogenic Microorganisms

Efforts have been made to explore the possibility of using garlic as an antimicrobial therapeutic agent since garlic extract and its individual sulfur compounds show antimicrobial activities against all kinds of microorganisms including bacteria, molds, yeasts and protozoa. Staphylococcus aureus has been the most studied bacteria along with many other Gram positive and negative pathogenic bacteria, including species of the genera Clostridium, Mycobacterium, Escherichia, Klebsiella, Bacillus, Salmonella and Shigella. Candida albicans has been the most studied among the eukaryotic microorganisms. A pathogenic protozoa, Giardia intestinalis, was also tested. All the microorganisms tested was inhibited by garlic extract or its sulfur components. Garlic has been known to be growth inhibitory only when fresh garlic is crushed, since allicin-generating reaction is enzyme-catalyzed. Allicin is known to be growth inhibitory through a non-specific reaction with sulfhydryl groups of enzyme proteins that are crucial to the metabolism of microorganisms. Another plausible hypothesis is that allicin inhibits specific enzymes in certain biological processes, e.g. acetyl CoA synthetase in fatty acid synthesis in microorganisms. Allicin transforms into other compounds like ajoene and various sulfides which are also inhibitory to microorganisms, but not as potent as their mother compound. It is reported recently that garlic heated at cooking temperatures is growth inhibitory especially against yeasts, and that the growth inhibitory compound is allyl alcohol thermally generated from alliin in garlic.

The contamination levels of 3-MCPD(3-Monochloropropane-1,2-diol) and 1,3-DCP(1,3-Dichloro-2-Propanol) in soy sauce, sauces was monitored. 105 samples were collected from June 2005 to August 2005 in Gyeonggi-do. 3-MCPD and 1,3-DCP were analyzed by GCMSD. As results, the detection range of 3-MCPD concentration was between 0.02 mg/kg and 0.27 mg/kg in soy sauce. However any samples were not detected with 1,3-DCP. The contaminated rates of 3-MCPD in soy sauce was 17.1%. Soy sauce is the representative vegetable protein hydrolyzed food. The reliable analytical method f3r the toxic 3-MCPD and 1,3-DCP in Soy sauce has been studied. The derivatization studies of 3-MCPD and 1,3-DCP were performed mainly as Silylation with BSA(N,O-Bis(trimethylsilyl)-acetamide). The retention times of derivative, BSA-MCPD, BSA-DCP were 11.30 and 10.12 minutes.

Asian Branches of International Life Science Institute (ILSI), i.e. China, India, Japan, Korea and South East Asian Region, identified five key public health issue priorities of each region and compared the results. In case of China, India and South East Asian countries (Indonesia, Malaysia, Philippines, Thailand etc. ASEAN countries), communicable diseases were the first priority issue, while elderly issue and food safety were prime issues for Japan and Korea, respectively. Malnutrition was the second priority issue for India and ASEAN countries, whereas non-communicable disease like cancer and degenerative diseases was for Korea and China, and obesity far Japan. Typical issues were smoking for China, nutrition education for China and Japan, biotechnology aiming GMO for India, and functional food causing health claim problem for Korea and Japan. Although the priority varied with the socioeconomic situation of each county, food and water safety recorded the highest priority of all the countries. The key public health issues of Korea were discussed in detail.

Peroxisome proliferatorr-activated receptor-gamma
must form a heterodimer with the retinoid-X receptor (RXR) to bind DNA, and its transcriptional activity is thought to be maximized by ligands specific for either receptor. Activated
ligands may influence tumor growth through regulation of the tumor suppressor PTEN. Our aim in this study was to determine whether co-stimulation with the
ligand, ciglitazone, and RXR ligand can synergistically upregulate PTEN in human acute promyelocytic leukemia (APL) cells and consequently potentate the inhibition of cell growth and cell cycle progression of these cells. Human leukemia cell line, HL-60 cells were exposed to all-trans-retinol and ciglutazone. The PTEN expression was measured as the level of PTEN mRNA expression by RT-PCR and as the level of PTEN expression by western blot analysis. Cell cycle analysis was carried out by a propidium iodide (PI) staining method and analyzed with a FACScan. The
ligand, ciglitazone, and the RXR ligand, retinoic acid, upregulated PTEN expression by HL-60 cells in time- and dose-dependent manners, respectively. This was significantly enhanced by a combination of both ciglitazone and retinoic acid. Moreover, these compounds synergistically induced arrests of both cell growth and the
phase of the cell cycle. Thus, the activation of the
:RXR heterodimer may represent a regulatory pathway for human leukemia cells and there may be important roles for
and RXR ligands in prophylactic and therapeutic approaches fur controlling leukemia through the upregulation of PTEN.

Tumor necrosis factor-alpha

This research was designed to evaluate the nutritional an microbiol quality assessment of Chungmukimbab purchased from market in Tongyeoung area. Contents of calories, calcium, iron, thiamin and riboflavin in ordinary kimbab and Chungmukimbab were lower than the recommended levels of Korean adult men. So, We suggested that a fruit, beverage and ffod stuff were supplemented to maintain nutritional balance. Total aerobic bacteria and coliform group of just prepared ordinary kimbab and Chungmukimbab samples from market were not significantly different, showing approximately
in ordinary kimbab,
in Chungmukimbab, respectively. Total aerobic bacteria of law ingredients of chungmukimbab sample were 3 to
in kimbab, seasoning squid and radish roots kimchi, 4 to
in boiled fish paste. The coliform groups were 1 to
MPN/100 g in kimbab, seasoning squid and radish roots kimchi, 2 to
MPN/100g in boiled fish paste. Detection rate of E. coli and Staphylococcus aureus counts were 10.0, 12.5% in Chungmu-kimbab, 15.0, 10.0% in seasoning squid, 0, 10.0% in radish roots kimchi respectively, not detected in boiled fish paste samples. During storage at
for 24 hours, total aerobic counts and coliform groups in ordinary kimbab and Chungmukimbab were increased by the 1.94,
, 0.60, 0.72 log10 MPN/100g respectively. Total aerobic counts of Chungmukimbab ingredients increased
at different time
