This study is carried out to investigate the analysis of nutrition and antioxidants of soybean Chungkukjang powder (SCP), Yak-Kong Chungkukjang powder (YCP) and Yak-Kong Chungkukjang powder added black foods (YCBP) for the management of Alzheimer's disease. The water content of YCBP was higher than that of SCP and YCP. The soluble and crude protein contents of YCP were the highest among three Chungkukjang powders. In SCP, YCP and YCBP, the ratios of unsaturated and saturated fatty acids were 5.17, 5.76, and 5.78, respectively. The mineral content of SCP was higher than that of YCP and YCBP. Antioxidants analysis showed that the content of diadzein was the highest in YCP and genistein, and anthocyanin contents were higher than the others in YCBP. In conclusion, YCP and YCBP had higher contents than SCP in soluble and crude proteins, and unsaturated fatty acids, which are needed for composition and function of the brain tissue. Also, it was found that the contents of diadzein, genistein and anthocyanin with outstanding antioxidative ability were high. Thus, this study suggests that Chungkukjang powder, which is made with Yak-Kong, black sesame, black rice and sea tangle, can be utilized for in vivo experiment for the control of oxidative stress, reported as cause and therapy for Alzheimer's Disease.

The Narim gold mine is located approimately 200km southeast of Seoul within the Muju mineralized district of the Sobaegsan gneiss complex, Korea. Environmental geochemistry were undertaken for various kinds of water (surface, ground and mine water) collected of April, September and November in 1998 from the narim mine creek. Hydrogeochemical compositions of water samples are characterized by the relatively significant enrichment of Na+K, alkali ions, $HCO_{3}$, $NO_{3}$, Cl and F in groundwater, wheras the mine and surface waters are relatively enriched in Ca+Mg, hea표 metals and $SO_{4}$. Therefore, the groundwaters belong to the (Na+Ca)-( $HCO_{3}+SO_{4}$) type, respectively. The pH and EC values of the non-mining creek surfers are relatively lower compared with those of the surface water of the mine and ore dump area. The d values ($\delta$D-8$\delta^{18}$O) of all kinds of water from the Narim mine creek are 5.8 to 13.1 The range of $\delta$D and $\delta^{18}$O values (relative to SMOW) are shown in distinct two groups as follows: for the April waters of -64.8 to -67.8$\textperthousand$ and -9.6 to -10.0$\textperthousand$(d value=10.1 to 13.1), and for the November waters of -65.9 to -70.2$\textperthousand$ and -9.3 to -9.6$\textperthousand$ (d value=5.8 to 7.9), respectively. This range variation indicates that two group water were composed of distinct waters with seasonal difference. Geochemical modeling showed that mostly toxic metals (As, Fe, Mn, Ni, Pb, Zn) may exist largery in the from of metal $(M2^+)$ and metal-sulfate $(MSO_4\;^{2-$\mid$),\; and \;SO_4^{2-$\mid$}$ concentration influenced the speciation of heavy metals in the meteoric water. These metals in the groundwater could be formed of $CO_3 \;and \;(OH)_3$ complex ions. Using computer program, saturation index of albite, calcite, dolomite in meteoric water show undersaturated and progreddively evolved toward the saturation state, however, ground and mine water are nearly saturated. The gibbsited water-mineral reaction and stabilities suggest that the weathering of silicate minerals may be stable kaolinite, illite and Nasmectite. The clay minerals will be transformed to more stable kaolinite owing to the contiunous reaction.

Diabetes mellitus is a multifactorial disease. Particularly, diabetic nephropathy is a serious complication for diabetic patients, yet the precise mechanisms that underline the initial stage of diabetic renal inflammation remain unknown. However, oxidative stress induced by hyperglycemia in diabetes is implicated in diabetic renal disease. We hypothesized that dietary supplementation of antioxidants either VCE (0.5% VC + 0.5% VE) or Comb (0.5% VC + 0.5% VE + 2.5% N-acetylcysteine) improves acute diabetic renal inflammation through modulation of blood glucose levels and antioxidant and anti-inflammatory responses. Experimental animals (5.5 weeks old female ICR) used were treated with alloxan (180 mg/kg) once. When fasting blood glucose levels were higher than 250 mg/dL, mice were divided into 3 groups fed different levels of antioxidant supplementation, DM (diabetic mice fed AIN 93G purified rodent diet); VCE (diabetic mice fed 0.5% vitamin C and 0.5% vitamin E supplemented diet); Comb (diabetic mice fed 0.5% vitamin C, 0.5% vitamin E and 2.5% N-acetylcysteine supplemented diet), for 10 days and then sacrificed. Body weights were measured once a week and blood glucose levels were monitored twice a week. Lipid peroxidation products, thiobarbituric acid reacting substances were measured in kidney. NF-${\kappa}B$ activation was indirectly demonstrated by pI${\kappa}B$-${\alpna}$ and expressions of selective inflammatory and oxidative stress markers including antioxidant enzymes were also determined. Dietary antioxidant supplementation improved levels of blood glucose as well as kidney lipid peroxi-dation. Dietary antioxidant supplementation improved NF-${\kappa}B$ activation and protein expression of HO-1, but not mRNA expression levels in diabetic mice fed Comb diet. In contrast, the mRNA and protein expression of CuZnSOD was decreased in diabetic mice fed Comb diet. However, antioxidant supplementation did not improve mRNA and protein expressions of IL-$1{\beta}$ and MnSOD in diabetic mice. These findings demonstrate that acute diabetic renal inflammation was associated with altered inflammatory and antioxidant responses and suggest that antioxidant cocktail supplementation may have beneficial effects on early stage of diabetic nephropathy through modulation of blood glucose levels and antioxidant enzyme expressions.

This study was performed to investigate the anthropometric data, serum profiles, and nutrient intakes of high school students who are living in Seoul. Anthropometric data showed that mean height and weight were 174.1 cm and 66.6 kg in 99 male and 161.4 cm and 54.0 kg in 116 female students. Mean BMl for male and female students were 21.9 and 22.3 kg/$m^2$, and subjects with BMI > 25 kg/$m^2$ were 14 and 7%, respectively. Total cholesterol, HDL- and LDL-cholesterol of subjects were 149.6$\pm 3.1,\; 46.4 \pm 1.3,\; 86.4 \pm 2.3$,/TEX> mg/dl for males and 169.2 $\pm 3.1,\;50.7 \pm 1.0,\; 100.9 \pm 2.7 mg/dl$ for females, respectively. Hemoglobin (Hb) and total iron binding capacity (TIBC) were 12.8 $\pm 0.1 g/dl, \;437.3 \pm 7.2\mug/dl\; in\; male\; and\; 11.9 \pm 0.1 g/dl,\; 439.4 \pm 5.7\mug/dl$ in female, respectively. Based on Hb classification, 45.6% of male and 45.0% of female students fell into anemic condition. Intakes of energy, Ca, Fe, Zn, riboflavin, and folate were below the Korean RDA. In particular Ca (male and female, respectively, 64.6 and 64.3% RDA) and Fe (male and female, respectively, 78.6 and 64.3% RDA) intakes were extremely low. Serum triglyceride was positively significantly correlated with weight (r =0.22), BMI (r =0.279), waist circumference (WC, r =0.235), triceps skin-fold thickness (TSF, r =0.197) and obesity index (OI, r =0.279). Hb concentration was positively correlated with height (r + 0.387), weight (r =0.349), BMI (r =0.191) and waistlhip ratio (WHR, r =0.380). As for the correlation between serum profiles and nutrient intakes, the Hb concentration was positively correlated with energy (r =0.163), protein (r =0.149), Na (r =0.153), vitamin A (r =0.165), thiamin (r =0.201) and niacin (r =0.192, p < 0.01). These result suggest that the prevalence of Ca and Fe deficiency of student is high and dietary guideline for prevent anemia in this age needs to contain the adequate intake of energy and its related vitamins.

We investigated the effects of organic acid and ultrasonication treatment in maintaining the quality of garlic during storage. Samples were exposed for 5 min to either ultrasonication at 60℃, 1% citric acid, or 0.5% fumaric acid. Presence of microorganisms and minerals, hardness, and color were compared during storage at 4℃ for 28 days. The total aerobic bacterial count remained low. No proliferation of Escherichia coli was observed after treatment with fumaric acid or ultrasonication, and mold proliferation was inhibited by ultrasonication. The mineral content of the northern type garlic was higher than that of the southern type. Exposure to fumaric acid did not result in a substantial difference in hardness until 21 days of storage, at which time there was a decrease in the L-value in each cultivation type. Our results indicate that treatment with 0.5% fumaric acid for 5 min was effective in reducing the abundance of microorganisms during storage without affecting the hardness or color in garlic.

This study was carried out to select the Eco-tree for successful phytoremediation of abandoned metalliferous mines. We examined vegetation and heavy metal concentrations of woody plants in abandoned mining areas, and also conducted seed germination and seedling growth experiment on contaminated soils from Gahak and Geumjeong mines. Pinus densiflora, Robinia pseudoacacia, Lespedeza bicolor and Alnus japonica showed high frequency in the survey areas and had high heavy metal concentrations compared to other species. Heavy metal concentrations were higher in roots than in leaves and stems. The seed germination rate was in the order of P. densiflora, L. bicolor, R. pseudoacacia, and Alnus japonica from the incubactor and greenhouse experiment. In the incubator experiment germination rate was highest in the control soil for P. densiflora and A. japonica. Germination rate of P. densiflora was highest on the 100% contaminated soil for Gahak mine while germination rate decreased with increased percentage of contaminated soil for Geumjeong mine. In the greenhouse experiment germination rate was lowest on the 40% contaminated soil for Gahak mine while germination rate was lowest on the 20% contaminated soil for Geumjeong mine and increased with increased percentage of contaminated soil. Shoot growth was highest for L. bicolor while root growth was highest for R. pseudoacacia except for 20% contaminated soil in Geumjeong mine.

This study is conducted to evaluate the effects of chelating agents for improving plant growth and reusing accumulated nutrients in soils of plastic film house. Two experiments were carried out at follows: i) The incubation test was conducted using soils treated with 0, 300 mM of EDTA and DTPA to examine the availability of nutrients. ii) For the pot test, chinese cabbages were cultivated in soils with 0, 0.1, 0.5, 1, and 5 mM of EDTA and DTPA to examine the impacts of plant growth response. The application of chelating agents increased ther availability of soil nutrients in the following order: DTPA > EDTA > control. Inorganic concentration of chinese cabbages in DTPA treatments consderably increased in nitrogen, phosphate, iron and aluminium contents than that of the other treatments. The optimal concentration of DTPA for vigorous plant growth as 0.5 mM. Thus, DTPA was more effective than other chelating agents for healty growth of cabbages and the availability of nutrients accumulated in plastic film house.

Experiment was conducted to elucidate the effect of various nitrogen fertilizers on the growth and yield of soybean cv. Backwoon in field, and to examine soybeans produced with different nitrogen fertilizers for their nutritional constituents and protein digestibility. Soybean plants were generally similar in growth among fertilizers applied, and plants with non-nitrogen and with ammonium sulfate showed tendency to have fewer internodes. Nodule number and nodule weight also were lower in plants with non-nitrogen and with ammonium sulfate. Nitrogen fixation ability per nodule number were similar at an early growth stage and at flowering stage treatments and were relatively higher with newly developed complex fertilizer at pod elongation stage. With newly developed complex fertilizer and with non-nitrogen, there were slight increase and in 100 grain weight and yield per 10a, respectively. Crude protein contents in soybeans with nitrogen fertilizers were higher than that with non-nitrogen, and the reverse were true for crude fat. Crude ash contents were relatively similar among the treatment. Crude fiber contents were higher with readily used complex fertilizer than with the others. The contents of inorganic constituents were of the same sort among the treatments, that of Fe with non-nitrogen being much lower than with the others. Protein digestibility was the highest in the non-nitrogen treated soybean.
