The formed acrylamide in many fried and baked starchy foods is in consequence of its formation during frying and preparation methods. Being acrylamide established to be a toxic substance, the implications to public health from amounts found in food are not clear. So this study was carried out to investigate the contents of acrylamide of French fries and snacks in addition to acrylamide formation in relation to water and lipid in foods. The raw materials of foods used in the experiments were wheat, potato, com and rice. The preparation of foods was modified in a little to raise the recovery ratio and contents of water and lipid were analyzed to the public food method. The contents of acrylamide were measured by the liquid chromatography tandem mass spectrometry. The average level of acrylamide produced in snacks is
ppb and potato snacks came out the highest value at
ppb in 104 snacks. The formation of acrylamide in fried food was found to depends on the composition of raw material not on water and lipid contents in food and not on storage period and temperature.

This survey was conducted to monitor the current status of pesticide residues in imported agricultural products circulated in Gwangju, 2005. A total of 108 samples was analyzed by multiresidue method. Of these samples, 32 were citrus fruits, 60 were tropical fruits and grapes, and 16 were vagetables. The origin was Philippine for 39 samples, U.S.A. for 36, China for 12, New Zealand for 11, Chile for 6, etc. The overall rate of detections was 30.6% and no samples had violative residues. Of citrus fruits,20 samples (62.5%) had residues and the residues were thiabendazole, imazalil, chlorpyrifos, etc. Of tropical fruits and grapes, 13 samples (12.0%) had residues and the residues were azoxystrobin, chlorpyrifos, carbendazim, captan, etc. 16 of vagetables had no detectable pesticide residues. Thiabendazole (71% in oranges and 56% in grapefruits) and imazalil (50% in oranges) were found in citrus fruits, which were frequently used as post-harvest pesticides. And azoxystrobin which is one of strobilurin fungicides, was often detected in mango, tropical fruit(27%).

Standard and lead limit test in general test method of Korea, Japan, Joint FAO/WHO Expert Committee of Food Additives (JECFA), USA, and EU on synthetic and natural food additives were compared. There were found that the general test methods in 'Korea Food Additives Code' were different from standards of various institutes on lead limit test. For the lead limit test of food additives, Korea used dithizone method, Japan used atomic absorption spectrophotometry, and USA used dithizone method, flame atomic absorption spectrophotometric method, atomic absorption spectrophotometric graphite furnace method, and APDC extraction method. In addition, JECFA and EU used dithizone method and atomic absorption spectrophotometric method. The dithizone methods of Korea, USA, and JECFA were nearly identical. In the case of USA, JECFA, and EU, the analytical methods for lead limit test were shown in individual monograph. Lead limit test against 13 synthetic, such as magnesium stearate and L-cystine, and 12 natural, such as gua gum and diatomaceous earth, food additives distributed in Korea were performed by the analytical method of each institute. Although all institutes use various methods for analysis of lead, contents of lead in food additives tested fell into the standard of each institute.

For standardization of quality and reduction of salt concentration of pickles manufactured in Folk Villages of Sunchang Region, the physicochemical characteristics of 90 pickles of 10 items were compared. Persimmon, garlic, cucumber, radish, Codonopsis lanceolata L., and Japanese apricot pickles were mixed with kochujang, perilla leaf pickle was mixed with soybean paste, cucumber pickle in wine cake was mixed with wine cake, and red pepper was mixed with soybean paste or soy sauce. Moisture contents, pH, and titratable acidities of pickles were various depend upon characteristics of materials. Sugar contents of pickles test,34 were ranged from
(red pepper pickled with soy sauce) to
(garlic pickle), and sugar contents of pickles mixed with kochujang were higher than those of soybean paste or soy sauce. Salt concentration of pickles were ranged from
(Japanese apricot) to
(red pepper pickled with soy sauce), and salt concentration of pickle mixed with soy sauce was the highest among the pickles tested. Total aerobic counts of pickles tested were similarly ranged from
(red pepper pickled with soy sauce) to
log CFU/g (perilla leaf pickled with soybean paste). These results indicate salt concentration and quality of pickles manufactured in Folk Villages of Sunchang region must be lowered and standardized, respectively.

The use of underarm and body care cosmetics with oestrogenic chemical excipients (particularly the parabens) and the hypothesized association with breast cancer incidence, particularly in women. It is noted that the type of cosmetic product is irrelevant (e.g. antiperspirant/deodorant versus body lotion, moisturizers or sprays versus creams) and attention must focus on issues of actual exposure to chemicals through continued dermal application of body care products and the endocrine/hormonal activity and toxicity of the chemicals in the formulations. To evaluate the estrogenic activities of parabens such as ethylparaben, butylparaben, propylparaben, isobutylparaben and isopropylparaben, we used recombinant yeasts containing the human estrogen receptor [Saccharomyces cerevisiae ER+LYS 8127], human breast cancer MCF-7 cell lines and human estrogen receptor
. In E-screen assays, isopropylparaben is the most estrogenic paraben, and in ER competition assay, isobutylparaben is the most estrogenic paraben. We evaluated isopropylparaben was most active in the recombinant yeast assay, followed by propylparaben, ethylparaben, isobutylparaben and butylparaben. Results from this study demonstrate that parabens are observed in human endocrine system. Therefore, we have shown that the parabens is induced the estrogenic activities similar to
-estradiol and Bisphenol-A.

Guh Sung Y.L.S-95 (GS95) is a kind of polyacidic solution, which contains acetic acid as a main component. We investigated in the present study tile genetic toxicity of GS95 according to the standard operation procedure from Korean Institute of Toxicology. In the Salmonella typhimurium reverse mutation assay using TA1535, TA1537, TA98 and TA100, GS95 did not induce mutation up to
. GS95 did not induce chromosome aberration in Chinese hamster lung fibroblast in the concentration range between 1.25 and 5 mg/mL. In the rodent micronucleus assay, the frequency of micronucleated polychromatic erythrocyte in GS95 treated mice were not increased up to 5,000 mg/kg compared to the vehicle treated mice. Taken all these data together, GS95 was proven to be nongenotoxic in the concentration ranges tested.

New nonspecific immunostimulators (Koko enterprise Co., Ltd., Korea) were evaluated for its effectiveness as a nonspecific immunostimulator in pigs. The effects of new nonspecific immunostimulators were determined by analysis of cytokines using ELISA and blood-chemistry. IFN-r which is one of the cell mediated immune cytokines significantly increased in DIR-vitamineral 0.2% group posttreatment 4 weeks and was significantly higher IMF 0.2%, DIR-vita 0.1% and DIR-vitamineral 0.2% groups than control group in 3 months. DIR-vitamineral 0.2% had a most strong effectiveness as a nonspecific immunostimulator in our treatment materials in pigs. IMF 0.2% and DIR-vita 0.1% were seen that there had effectiveness of a nonspecific immunostimulator in posttreatment 3 months. IgG IgM and Total Ig which were humoral immune globulins, were not significantly changed in posttreatment 4 weeks and 3 months. In conclusion, this study has demonstrated that new nonspecific immunostimulators had an immunostimulatory effect on pigs through cell mediated immune response.

This study was conducted to determination of the endocrine distruptor function of 'Parabens' by dosing ethyl paraben, propyl paraben, isopropyl paraben, butyl paraben and isobutyl paraben to the immature SD rats. 18 groups were given vehicle control group, negative control group (Dibutyl phthalate), postive control group (
Ethynylestrdiol) and each paraben groups involved 3 dose level. Rats were injected with 62.5, 250 and 1,000mg/kg from postnatal day 19 till 21 once a day in subcutaneous and a total 3, times. There was no treatment related death. but, subcutaneous nodule, edema, alopecia and scrub formation on injection site was observed. These signs was become worse in high dose level. these signs was cause from physical stimulation by test substance which parabens were mix with com oil as vehicle. In the analysis of organ weights, absolute and relative weights of brain, spleen, liver, thymus, heart, kidneys, adrenals, ovaries and vagina were no difference with control group. but, wet and blotted weight of uterus was increased in every high dose parabens treat group. Especially, all dose level of isobutyl paraben was showed increment of uterus weight. uterus dilatation of parabens treated group was observed in gross anatomic pathology and these result was agree with wet and blotted weight of uterus. In the result of this study, estrogenic effect as endocrine distruptor was observed in ethyl paraben, propyl paraben, isopropyl paraben, butyl paraben and isobutyl paraben. and it was considered isobutyl paraben has highest estrogrnic effect under the condition of this study.
