The antioxidative and antimicrobial activity were carried on the Chopi(Zanthoxy1um pippentum) extracts by six kinds of solvents in order to find out new natural food additives. Six solvents were used methano(MeOH), n-hexan(hexane), chloroform(CHCl_(3)), ethylacetate(EtOAc), buthano(BuOH), and water(water and methoanol extract(MEex), hexan extract(HEex), chloroform extract(CHex), ethylacetate extract(EAex), and buthanol extract(BUex), water extract(WAex). The antioxdative activities of them extracts were determined by peroxide value(POV), conjugated diene value(CDV) of corn germ oil storaged for 30 days at 60±2℃. These extracts were added as 0.02, 0.1, 0.2% of each extracts and compared with a-tocopherol, and BHT. The antioxidative activities of 0.02% extract were as follows in decreasing order BUex >WAex, BHT, MEex>HEex, EAex, CHex>TOC, and control. While, BUex and CHex among these extracts were shown to be had antimicrobial effects on the microorganism such as Escheria coli, Salmonella typhimurium, Psedomonas aeruginosa, Staphylococcus aureus, and Listeria monocytogenes. Finally to find out the preference of chopi we had made Yugwanzageon (a kind of shallow fried meat ball )by adding chopi powder. The result were similar to control( not added chopi powder ) in case of 0.1% chopi adding Yugwanzageon . (p<0.05) therefore it was thought to be possible that chopi powder was used Yugwanzageon preperation.

The antioxidative and antimicrobial activities were carried on the leeks (Allium tuberosun R.) ethanol extracts in order to find out new food functional components. Three species of leeks used in this study were Chinese leek(long type, LL), general leek(medium type, LM), and medicinal leek (short type, LS). Total amounts of polyphenol compounds in LS was shown as the highest (436.60㎎%) value. All of ethanol extracts of these leeks were shown to be had good electron donating ability(EDA) and nitrite scavenging activity. Specially, the ethanol extract of LS(LSEx) had the highest EDA 30.47% and nitrite scavenging activity 77.24% and the lowest was LMEx. The antioxidative activities of these ethanol extracts on the corn germ oil were measured by peroxide values(POV) and conjugated diene values (CDV) storaging for 30 days at 60±2℃. The antioxidative activities of these extracts by POV and CDV were determined as following order as LSEx> LLEx> LMEx. The antioxidative activities of all extracts were presented as high tendency by increasing adding amounts (0.02%〉0.05%〉0.1%). When the antioxidative activities were compared with BHT and a-tocopherol, the degree of the antioxidative activities of these extracts were certified as lower than BHT and higher than a-tocopherol. And also LSEx, LMEx, and LLEx had antimicrobial effects on the several micro organisms, especially the effect on the Pseudomonas aeruginasa was remarkable. While LMEx had shown inhibit effect on most of micro organism used in this study.

Background : In the previous stuides, we identified that the interferon-r activated sequence (GAS) in the 5-flanking region of rat ICAM-1 gene is major element for interferon-r-inducible expression of the gene in rat thyroid cells, FRTL-5. We here, investigated the role of transcriptional coactivators, CBP(CREB binding protein) and CⅡTA (class Ⅱ transactivator) in the modulation of the activity of GAS which could interacts with signal transducers and activators of transcription-1 and 3 (STAT1 and STAT3). Methods : The expression of CBP RNA and protein were quantitated in FRTL-5 after stimulation with interferon-r (IFN-r), thyroid stimulating hormone (TSH), forskolin and methimazole. Direct association of CBP with STAT were analyzed by immunoprecipitation. The transcriptional roles of CBP and CⅡTA in the regulation of GAS were assessed by the cotransfection with their expression vectors with reporters; 5-deletion constructs of rat ICAM-1 promoter or 8xGAS-luc constructs, into FRTL-5 thyroid cells. Results : The level of CBP RNA and protein were not changed by the treatment with TSH, IFN-r, forskolin and methimazole in FRTL-5, FRT and BRL liver cells. The CBP could be directly associated with STAT1. Furthermore, the overexpression of CBP significantly increases the both promoter activities; rat ICAM-1 gene promoter which has GAS element and 8xGAS-luc cassette constructs. However, the cotransfection of CⅡTA decreased the constitutive and CBP-mediated transactivation of rat ICAM-1 promoter and 8xGAS-luc cassette constructs. Conclusion : We identified that the two tanscriptional coactivators; CBP and CⅡTA has differential roles in the regulation of transcriptional activity of GAS drived promoter. CBP increases the GAS activity through the direct binding with STAT1, but CⅡTA inhibited the CBP-mediated transactivation of GAS activity.

This experiment was conducted on persimmon (Diospyros kaki Thunb) to study the cultural method reducing preharvest drop through analysis of the character of dropped fruit, thinning degree and the nutrient state of tree. Fifteen 10-year-old 'Hachiya' persimmom trees were used. Thinning were applied to one fruit per one twig (A treatment), one fruit per two twigs (B treatment) and one fruit per three twigs (C treatment) which had about six-leaf on 20 June. The number of fruit seed was investigated on dropped and harvested fruit on 20 June, 11 July and 1 Oct. Leaf analysis was conducted on both tree with heavy fruits drop and tree without fruit drop on 20 July, 1999. Preharvest drop rate with thinning degree tended to more decrease in B treatment and C treatment than in A treatment and harvest quantity of fruit was higher on B treatment than on C treatment. Preharvest drop rate seemed to be higher on the upper part of tree than on the lower part. The number of seed in fruit was about 2.1 per dropped fruit and 3.9 per harvested fruit, which showed the tendency that Preharvest drop was decreased in the fruit with many seeds. The tree with high preharvest drop rate has lower N, Ca, Mg concentration and higher Mn concentration within leaves than that with low preharvest drop rate. Thinning degree, setting point and the number of seed in fruit, the concentration of mineral nutrient in leaf had an effect on preharvest drop. Therefore we guessed that movement and supply of nutrient could affect preharvest drop.

단일 기판위에 온도측정용 Pt 박막과 Pt 히터 그리고 가스 감지를 위하여 순수한 SnO_2 박막과 Pt가 첨가된 SnO_2박막을 설계하고 제작하였다. 제작된 소자는 실내환경가스인 이산화탄소, 프로판 그리고 부탄의 분류에 응용되었다. 동작 온도를 가변하기 위하여 히터의 입력 전압을 사다리꼴로 인가하면서 SnO_2 감지막의 반응특성과 실내환경가스들에 대한 분류여부를 조사하였다. 감지막 반응특성곡선에서 여러 변수들을 추출한 후 주성분분석(principal component analysis : PCA)을 통하여 가스 분류 특성을 검증하였다. Two SnO_2 based sensing films(pure SnO_2 and SnO_2/Pt) and a Pt thin film for temperature sensor on an alumina substrate were designed and fabricated for classifying the indoor environmental gases. By controlling the heating power in the shape of trapezoid, unique four sensing response curves created from both SnO_2 film and SnO_2/Pt film. Then, various parameters were extracted from sensing response curves and carried out principal component analysis(PCA). The results confirm that a sensor array with the proposed operating mode was extremely effective in classifying indoor environmental gases such as CO_2, C_3H_8, C_4H_10.

To evaluate the in-vivo effects of mitomycin-C-polyglycolic acid composite(MMC-PGA) the disk: shaped composite were implanted into the peritoneal cavity of the Sprague-Dawley rats. The pathologic changes were examined at various time points up to 12 weeks. Initially the soft tissue around the inserted disks showed capillary congestion at 3 days. Inflammatory infiltrates with foreign body giant cells appeared from the 2nd week and reached peak response at 6-8 weeks. These reaction diminished prominently at 12 weeks. No specific pathologic change was found in the liver, the kidneys, and the heart. The above results suggest that the MMC-PGA composite can serve as a new device for intraperitoneal chemotherapy of various types of cancers.
