This study was conducted to find material having antibacterial activity. The effects of preservatives, antibiotics and oriental medicines on growth of tested microorganisms were investigated. The growth of all tested bacteria was inhibited by water extract of Schizandra chinensis. Antibacterial activity on the concentration of Schizandra chinensis extract was tested. The growth of Escherichia coli W3110, Enterobacter cloacae MG82 and Salmonella typhimurium was extraordinarily inhibited by more than 0.2% concentration of Schizandra chinensis extract. The specific growth rate of Escherichia coli W3110, Enterobacter cloacae MG82 and Salmonella typhimurium under control condition had mean values of 0.514(hr-), 0.381(hr-) and 0.489(hr-), respectively. When 0.2% of Schizandra chinensis extract was added, specific growth rates of Escherichia coli W3110, Enterobacter cloacae MG82 and Salmonella typhimurium were decreased, compared to control, in 1.26, 2.23 and 1.50 fold, respectively. Minimal inhibitory concentration of Schizandra chinensis extract was 0.25% on the tested microorganisms. The growth of Enterobacter cloacae MG82 was more inhibited by Schizandra chinensis extract than other tested microorganisms.

Predictive food microbiology(PFM) is an emerging area of food microbiology since the later 1980's. It does apply mathematical models to predict the responses of microorganism to specified environmental variables. Although, at present, PFM models do not completely developed, models can provide very useful information for microbiological responses in HACCP(Hazard Analysis Critical Control Point) system and Risk Assessment. This study illustrates the possible use of PFM models(PMP: Pathogen Modeling Program win5.1) with milk in several elements in the HACCP system, such as conduction of hazard analysis and determination of CCP(Critical Control Points) and CL(Critical Limits). The factors likely to affect the growth of the pathogens in milk involved storage temperature, pH, Aw and NaCl content. The variable factor was storage temperature at the range of 4-15℃ and the fixed factors were pH 6.7, Aw 0.993 and NaCl 1.3%. PMPwin5.1 calculated generation time, lag phase duration, time to level of infective dose for pathogens across a range of storage temperature. The levels of safety associated with milk which were defined based on various storage temperature as affecting microbial growth according to PMPwin5.1 were classified in $quot;safe temperature zone$quot;, $quot;caution temperature zone$quot; and $quot;danger temperature zone$quot;, respectively. These zone ranges were determined by the lag phase duration and time to level of infective dose based on shelf life of milk, which is required 5 days in domestic legal. These results can be used to conduct a hazard analysis and set the criteria for CCP or CL. Though PFM contains limitation in the use, PFM models can be useful instrument to support of guarantee of food safety.

This study was carried out to evaluate the irritant potential of P-toothpaste in hamster cheek pouch. The test materials were applied once at the beginning of this study into right pouches of hamsters and maintained for 14 days. Animals were administered with P-toothpaste, Bamboo salt toothpaste, D.W. and control solution, respectively. In order to evaluate the irritant potential in mucosa of hamster cheek pouch, we observed clinical signs, mortality, body weights and gross and histopathological findings for 14 days. In all groups, there were neither dead animals nor significant changes of body weights. In addition, there were no differences between D.W. and Ptoothpaste treated group in gross and histopathological findings. Therefore, these results suggest that there was little irritant potential of P-toothpaste in hamster cheek pouch.

The main constituent of green tea, catechins have been reported to have numberous biological activites including antimutagenic, antibacterial, hypocholesterolemic, antioxidant and antitumor properties. In the present study, we examined the protective effect of catechin on UVB-induced skin damage. Catechin (3 mg/mouse) was topically treated to dosal area of SHK-1 hairless mouse daily for 2 weeks. UVB (100 mJ/㎠) was also treated soon after application of catechin alone or with catechin for 2 weeks. Catechin reduced UVB-induced infiltration of inflammatory cells, fibrosis of cells and collagen-fiber formation. In addition, catechin also prevented UVB-induced DNA fragmentation and apoptosis cell number, but not changed p53 level. Furthermore catechin inhibited UVB-induced cell proliferation. There results showed that catechin have preventive effect against UVB-induced skin damages, and these effects could contribute to the antitumor promotors activity.

The present study was conducted to investigate biological degradability of phosphamidon and profenofos. In the biodegradation test of two pesticides by the modified river die-away method from May 20 to July 29, 1999, the biodegradation rate was determined in Nakdong (A) and Kumho(B) River. The residual percentages of phosphamidon were 74.9%, 68.8% and 62.7% in control, A and B samples 7 days after application, respectively. Biodegradation constants and half-lives of phosphamidon were 0.0005 and 58.6 days in A, 0.0012 and 23.8 days in B, respectively. The residual percentages of profenofos were 25.1%, 21.9% and 11.9% in cotrol, A and B samples 7 days after application. Biodegradation constants and half-lives of profenofos were 0.0005 and 58.4 days in A, 0.0013 and 21.6 days in B, respectively. The biodegradation rates of phosphamidon and profenofos were higher in the Kumho River(B) than in the Nackdong River(A). The strains of microorganisms for the degradation of phosphamidon and profenofos were identified as Klebsiella pneumoniae, Aeromonas hydrophila and Acinetobacter calcoaceticus, all Gram-negative bacteria. In order to identify biodegradate products, the extracts of cultivates were analyzed by GC/MS. The mass spectra of biodegradate products of phosphamidon were at m/z 153 and 149, those of the profenofos were at m/z 208 and 240, respectively. It was suggested that the biodegradate metabolites of phosphamidon were O, O-dimethyl phosphate (DMP) and N, N-diethylchloroacetamide, those of profenofos were 4-bromo-2-chlorophenol and O-ethyl-S-propyl phosphate.

A 5-day germination test is applicable to detect biological changes in irradiated wheat and barley at low doses. Seeds were irradiated at below 0.5 kGy, husked and placed on distilled water-moistend filter paper in a covered Petri-dish. Water was supplied everyday. To evaluate the growth rate, the length of shoots and roots was measured during germination. In wheat, the shoots of all samples grew well during 5 days, but the shoot length and the daily growth extent decreased with increasing doses. The roots of non-irradiated wheat showed the highest daily growth extent during 5 days and the root length was over 20 mm at 3rd day. In barley, the growth of shoots and roots was retarded at 0.3 kGy or more after 3 days. It was concluded that if the root length was 20mm or longer within 3 days, wheat and barley were identified as non-irradiated. The germination test was proved a promising screening method for the detection of irradiated wheat and barley.

A survey of consumers' awareness and attitudes about food biotechnology was conducted during May through August of 2001 with a random sample of 750 Korean consumers. More than 70% of the respondents was exposed to some informations related to genetically modified (GM) foods. The greatest benefit of the development of GM foods was thought to be the remedy for the food shortage in the future. More than 90% of Korean consumers wanted GM foods labeled. About 20% of the respondents would buy GM foods voluntarily, whereas over 50% would not until they found out more. More consumers responded that they would not buy herbicide-tolerant GM soybean but buy vitamin-enriched GM soybean. It seemed to be that many Korean consumers do not make decisions of acceptance or rejection of GM foods not on the basis of biotechnology but on the basis of the words) used to describe the products, such as herbicide and vitamin. Only 4% of Korean consumers responded that GM foods were the greatest safety-threatening factor of Korean foods and that the most interested information on food labels was whether the food was produced by biotechnology.
