  • To investigate the role of vitamin E in protection against lipid per-oxide formation and to monitor the changes in the status of vitamin E. A and reduced glutathione(GSH) in fish oil feeding male Sprague-Dawley rats were divided into four groups. Control group was fed soybean oil and fish oil groups(FO, FI, FII) fed menhaden oil and soybean oil(9:1) mixture at the level of 10% (w/w) respectively. Dietary vitamin E levels were 30 T, E for control and FI, 2 T.E. for FO and 140 T. E for FII Feeding periods were 4, 8, and 16 weeks. Throughout all periods plasma vitamin E levels(either per ml or per mg lipid) of FO group were extremely low and liver and adipose tissue vitamin E levels were also the lowest among four groups, Plasma vitamin E levels per ml were lower in FI and FII than control but per mg lipid were in the order of FII>FI$\geq$control but vitamin E level per mg lipid did not differ in liver and adipose tissue. As feeding prolonged vitamin E levels in plasma and other tissue were decreased in FO but increased in the other groups. Plsama and liver thiobarbituric acid-reactive substance(TBARS) values were elevated in FO. but increased in the other groups. Plasma and liver thiobarbituric acid-reactive substance(TBARS) values were elevated in FO. While plasma TBARS values as per ml plasma were similar or lower in FI and FII as compared to control plasma TBARS values as per mg lipd and liver TBARS values were in the order of $FI\geqFII>control.$ Plasma and liver vitamin A blood GSH but not liver GSH appeared to be in the order of FII control>FI>FO and this was most significant in 8 weeks. This results suggests that both type of dietary oil and levels of vitamin E affect not only lipid peroxidation but also the status of other physiological antioxidants which have the potential to spare the role of vitamin E.

  • Polysaccharides were prepared from Orostachys japonicus by extration with hot steam water (OJPl). The OIPl fraction was further purified by Sephadex G-50 gel filtration chromatography to produce FI (polysaccharides) and FII (oligosaccharides) fraction. The average molecular masses o fFI and FII fraction were determined to be 3050 kDa and 13 kDa, respectively. The antimicrobial activity of OIPl was tested against 8 strains of bacteria and one strain of yeast by the disc diffusion method, fluorescein diacetate (FDA) method and broth dilution method. The OIPl exhibited a very strong growth inhibition to Candida albicans. The OIPl remarkably sup­pressed the growth of Salmonella typhimurium and Staphylococcus aureus. The OIPl showed higher growth inhibition to Escherichia coli and Pseudomonas aeruginosa than propolis, positive control. When the anticancer activity of the OIPl, FI or FII was examined against human cancer cell lines and the Sarcoma 180 cells, these widely suppressed the proliferation of cell lines in the MTT assay and morphology study. Especially, they remarkably inhibited the growth of A549, HeLa and AGS cells. Also treatment of cancer cells with OJPl, FI or FII induced apoptotic cell death characterized by DNA fragmentation. The OJPl, FI or FII exhibiting various biological activities such as antimicrobial activity and anticancer activity is expected to be developed as new biohealth products.

  • The effect of stb locus of E. COLI IncFII plasmid NR1 on the stability of chimeric plasmids was investigated. First, we have isolated the stability locus (stb) from E. coli NR1 plasmid and then inserted into the three different vectors, pUC8, YRp17 and YEp24. By examining their stability in E. coli and yeast, we showed that the recombinant plasmids containing stb locus were resonably stable. Also, by comparing the amounts of the rDNA fragments per haploid genome with those of the plasmid fragments, we showed they copy number of recombinant plasmids was not increased. Consequently, the stb locus of E. coli IncFII plasmid NR1 stabilized the chimeric plasmids but did not affect the replication or copy number of plasmids.

  • Background: Nasal fractures have a tendency of resulting in structural or functional complications, and the results can vary according to the type of nasal bone fracture. The aim of this study was to evaluate the objective postoperative results according to the type of nasal bone fractures. Methods: We reviewed 313 patients who had a closed reduction of nasal bone fracture. The classification of nasal bone fracture by Stranc and Robertson was used to characterize the fracture type: frontal impact group type I (FI), frontal impact group type II (FII), lateral impact group type I (LI), lateral impact group type II (LII), and comminuted fracture group (C). For each patient, we tried to use the same axial image section of computed tomographic (CT) scans before and immediately after operation. Postoperative outcomes were classified into 4 grades: excellent (E), good (G), fair (F), and poor (P). We also analyzed postoperative complications by fracture type. Results: Regarding the postoperative CT images, 189 subjects showed E results, 99 subjects showed G, 18 subjects showed F, and 7 subjects showed P reduction. The rate of operation results graded as E by each fracture type was 66.67% in FI, 52.0% in FII, 64.21% in LI, 62.79% in LII, and 21.74% in C. Complications of FI (7.14%), LII (13.95%), and C (13.04%) groups occurred more than in the FII (4.00%) and LI (4.21%) groups. Conclusion: It seems that the operation result by fracture type was better in the FI, LI, and LII type than the FII and C type; after one month, however, LII type showed more complications than other types. The septal fracture can be thought to affect early reduction results in nasal bone fractures.

  • In India, forest based insect enterprises has never been linked up with any forest management activity, either as a forest conservation strategy or to reduce the poverty in forested area. This investigation indicated that when forest dependent people are associated with forest insect industry (FII) like forest sericulture, lac culture or apiculture; this income generating activity links livelihood with forest conservation, and generates a viable model of collaborative forest management (CFM). In this model different stakeholders work together as a coherent entity for unified goal of managing the forest for well-being of the poor people in fringe areas. Article summaries and evaluates the prospect of India specific forest insect industry, and discusses how and to what extent integration of FII could be a viable livelihood component in CFM to conserve the forest and insect biodiversity. We analysed a case study on forestbased rearing of tropical tasar silkworm rearing in Central India from CFM perspective. Arguments in this communication are intended to provide forest managers and policy-makers with necessary input to consider location specific FII in CFM mode to provide a continuous source of small income to forest dependent people to ensure long lasting success of their forest management endeavours.

  • This study applied risk indexes to the disaster flow event occurred at Mt. Umyeon region in 2011. A 2D hydrodynamic model was employed to calculate flow characteristics, and the model was validated against two dam break flow problems conducted by Bellos and EU CADAM project. The model performance was shown to be satisfactory. In order to determine which index is more appropriate to assess the vulnerability of debris flow, 3 risk indexes (FII, FHR and VDI) were considered. It was found that VDI, which determines the risk level only by the velocity factor, consistently predicted the risk level corresponding to 6 because the velocity range was widely organized. However, in the case of FII and FHR, the risk was reasonably quantified due to combined consideration of significant factors of flow velocity and debris thickness. Therefore, FII and FHR are expected to be more accurate than VDI. However, two indexes still need to be improved to include major factors such as debris density or material properties.

  • Ethyl acetate and butanol fractions among the serial solvent fractions of grape seed ethanol extract contained the catechin at the levels of 35.7 mg/g and 20.2 mg/g, respectively However, the POV increasing patterns of two linoleic acid samples containing each solvent fraction were so similar that the difference in antioxidant activity by the catechin content of each solvent fraction could not be found. Each solvent fraction was fractionated on C18 cartridges into three subfractions which were mono-, dimers fraction (FI), oligomers fraction (FII) and polymers fraction (FIII) to examine the effect by the difference in degree of Polymerization of proanthocyanidin. The catechin contents of ethyl acetate subfractions (E-F) were in the order of E-FI (26.0 mg/g) > E-FII (18.6 mg/g) > E-FIII (13.7 mg/g) but the three subfractions showed nearly similar antioxidant activities, by the POV measurement at 1,000 ppm concentration. Also the catechin contents of butanol subfractions (B-F) were in the order of B-FI (35.3 mg/g) > B-FII (30.8 mg/g) > B-FIII (22.7 mg/g) but similar antioxidant activities were observed in all subfractions. In this study, similar antioxidant activities of each solvent subfraction in spite of different catechin contents inform that the degree of polymerization of proanthocyanidin as well as the total catechin content should be considered in quality control of grape seed extract produced for natural antioxidant.

  • The present study was carried out to determine the effects of feeding levels of barley grain in diets of Hanwoo on the growth performance and carcass characteristics of Hanwoo. Twenty Hanwoo bull calves (initial mean body wt. 99kg) were randomly divided to examine the effects of 5 feeding levels of barley grains(addition levels: 0, 0 and 40% for FII40; 0, 0 and 60% for FII60; 0, 20 and 40% for F2040; and 0, 20 and 60% for F2060 during the growing, early fattening and late fattening periods, respectively) on growth performance and meat quality. Body weight was not affected by the feeding level of barley grains through the whole experimental period, although the body weight of Hanwoo bulls fed FII40 diet at 24 months old of age tended to be lower(591.5kg) than that of other animals(606.2~614.6kg). However, body weight gain in the bulls of the FII60 diet was slightly increased(P<.19). The feeding levels of barley grains did not influence on fasting body weight, carcass weight, carcass rate, lean meat, retailed cut, KPH fat and bone yield. The lean meat yield(89.82%) and fat yield(20.28%) tended to increase in Hanwoo bulls fed the F2060 compared with other treatments. Feeding of the diets of FII40 resulted in the higher marbling scores as 3.75, respectively than other diets.

  • A novel inhibitory protein against blood coagulation factor Va (FVa) was purified from muscle protein of granulated ark (Tegillarca granosa, order Arcoida, marine bivalvia) by consecutive FPLC method using anion exchange and gel permeation chromatography. In the results of ESI-QTOF tandem mass analysis and database research, it was revealed that the purified T. granosa anticoagulant protein (TGAP) has 7.7 kDa of molecular mass and its partial sequence, HTHLQRAPHPNALGYHGK, has a high identity (64%) with serine/threonine kinase derived from Rhodopirellula baltica (order Planctomycetales, marine bacteria). TGAP could potently prolong thrombin time (TT), corresponding to inhibition of thrombin (FIIa) formation. Specific factor inhibitory assay showed that TGAP inhibits FVa among the major components of prothrombinase complex. In vitro assay for direct-binding affinity using surface plasmon resonance (SPR) spectrometer indicated that TGAP could be directly bound with FVa. In addition, the binding affinity of FVa to FII was decreased by addition of TGAP in dose-dependant manner ($IC_{50}$ value = 77.9 nM). These results illustrated that TGAP might interact with a heavy chain of FVa ($FVa_H$) bound to FII in prothrombin complex. The present study elucidated that non-cytotoxic T. granosa anticoagulant protein (TGAP) bound to FVa can prolong blood coagulation time by inhibiting conversion of FII to FIIa in blood coagulation cascade. In addition, TGAP did not significantly (P < 0.05) show fibrinolytic activity and cytotoxicity on venous endothelial cell line (ECV 304).

  • Cytotoxicity of dental restorative materials using cell culture technique has been extensively studied by various quantitative assays. The aim of this study was to investigate the microstructural change of damaged L292 cells which could not observed with light microscope. Cytotoxic effect of ZOE, Prisma APH (Densply International Inc., U.S.A.), Clearfil FII(Kuraray Co., Japan), Fuji II(GC Co., Japan) and Fuji II LC(GC Co., Japan) on cultured L292 cells were observed. Irreversible cell damage and cytolysis were found in ZOE and Fuji II groups. In Clearfil FII, mild to moderate cell damage was observed. APH group showed variable cytotoxicity. Moderate cell damage was found in Fuji II LC group. Cytotoxic effect were as follows : A condensation of the chromatin occureds along or adjacent to the inner membrane of the nuclear envelops. The nuclear envelope remained resonably intact but the contents were partially or completely lost. The cell nucleus contains clusters of markedly electron-dense interchromatin granules. The rough endoplasmic reticulum were dilated. In some mitochondira, matrix was disoriented and fused cristae were discernible. Mitochondiral swelling and woolly appearance were recognized. Large vacuoles and autolysosmes were found in cytoplasm. Some breaks of the cytoplasmic membrane and even cytolysis could be seen in dying cells.
