Opuntia ficus-indica var. sabotan was administered with diet for 5 weeks on db/db diabetic mice and its antidiabetic activity was investigated. Leaves of Opuntia ficus-indica var. sabotan inhibited the increase of body weight, glucose elevation in blood and urine, and protein excretion in urine, and protein excretion in urine. Opuntia ficus-indica var. sabotan also inhibited the intestinal maltase and sucrase activity on db/db Mice loaded with maltose and sucrose. However, it did not significantly lower HbAlc in blood of db/db mice. These results suggest that leaves of Opuntia ficus-indica var. sabotan could be effective on insulin-independent diabetic mellitus type 2.

The effect of hemicellulose extracted from Shiitake mushroom(Lentinus edodes) on the level of blood sugar and cholesterol in the diabetes-induced rat by streptozotocin(STZ) was investigated. The yield of hemicellulose by extraction process of 5% salt extraction, preparation of alcohol insoluble substance, IN KOH extraction, acid precipitation(pH 3.0), and dialysis was 9.24%. The experimental plots divided to 1% cellulose group(control), 0.5% hemicellulose group(H-l) and 1% hemicellulose group(H-2). The groups were fed for 6 weeks, then continuously fed for 1 week after induction of diabetes by STZ. Feed intakes, weight gain and feed efficiency of the each groups were not significantly different, while water intakes and liver weight of H-2 group were lower than those of control and H-l group. Weight of liver in the H-2 group was significantly lower than those of control and H-l groups. The amounts of feces were 0.32 g/day in the control group, 0.43∼0.44 g/day in the H-l and H-2 groups, while the amounts of urine were 15.28 mL/day in the control group, 10.83∼11.20 mL/day in the H-l and H-2 groups. The content of blood glucose before diabetes induction(fed for 3∼5 weeks) was 111.2-132.6 mg/dL in the control group, not significantly different from others; After diabetes induction, however, the contents were 212.8 mg/dL in the control group, 140.0-144.0 mg/dL in the H-l and H-2 groups, which showed significant difference. Urine glucose contents of H-2 group before and after diabetes induction were lower than those of control and H-l groups. There was no significant difference in the content of neutral lipid between each groups. Total cholesterol contents were 101.6 mg/dL in the control group, 56.∼64.0 mg/dL in the hemicellulose groups. HDL-cholesterol content and atherogenic index of hemicellulose groups were lower than those of control group, respectively. In conclusion, the hemicellulose extracted from Shiitake mushroom represented improving and preventing effects for diabetes.

The purpose of this study was to investigate zinc and copper metabolism and risk factors of chronic diseases in 20 normal adults women. The daily intake, excretions in urine and feces, and serum levels of zinc and copper were determined by 24-hr food records and chemical analysis. The results were summarized as follows. mean age, body weight and BMI were 22.88 years, 54.65kg and 21.28kg/$m^2$ respectively. Mean daily intakes of energy and protein were 1578.84㎉(79% of RDA) and 52.05g (87% of RDA). The zinc and copper intake, excrestion in urine and feces were 7093.23$\mu\textrm{g}$(59% of RDA/2093.87$\mu\textrm{g}$, 203.50$\mu\textrm{g}$/39.87$\mu\textrm{g}$ and 3416.41$\mu\textrm{g}$/857.62$\mu\textrm{g}$, respectively. The serum levels of fasting glucose, insulin, total cholesterol, HDL-cholesterol, LDL-cholesterol, triglyceride, zinc and copper were 76.60mg/㎗, 15.66IU/㎗, 160.30mg/㎗, 50.95mg/㎗, 89.80mg/㎗, 89.79mg/㎗, 95.65$\mu\textrm{g}$/㎗ and 73.28$\mu\textrm{g}$/㎗ respectively. Dietary ratio of Zn to Cu was shown to have significant positive correlations with serum insulin, total cholesterol, LDL-cholesterol. The urinary ratio of Zn to Cu was shown to have significant positive correlations with triglyceride. The serum copper level was shown to have significant negative correlations with serum total cholesterol and LDL-cholesterol. In summary, Zn consumption of adult women in their normal diet does not meet the Zn requirement for Koreans. Also, intakes of Zn and Cu may effect the glucose metabolism and cardiovascular diseases. Therefore, to increase the Zn intake and to maintain an appropriate intake ratio of Zn to Cu, nutrition education needs to be implemented.

The effects of Geumguesingitang and Dohongsamultang on rats with nephrosis induced by a single tail-intravenous injection of puromycin aminonucleoside(PAN), 2.5mg/l00g of body weight were evaluated in the present study. The effects of Geumguesingitang and Dohongsamultang on PAN nephrosis were evaluated by measuring (1)the concentrations of albumin, total protein, total lipid, cholesterol, triglyceride, creatinine, blood urea nitrogen(BUN) and uric acid in the serum, (2)the concentrations of protein, creatinine, glucose, occult blood and volume of the 24 hours urine and (3)the volume of intake water. The results are summerized as follows; 1. In the Control group as compared to the Normal. the amount of protein of 24 hours urine was significantly increased, the concentrations of albumin and total protein were significantly decreased. Total lipid, cholesterol and triglyceride in the serum were significantly increased. The concentrations of creatinine, BUN, uric acid in the serum, the amount of glucose and occult blood of 24 hours urine were also increased significantly. 2. In the Geumguesingitang group as compared to the Control, the increase in the amount of urinary protein during 24 hours induced by PAN was significantly suppressed, and the concentrations of total protein and albumin in the serum were significantly increased. The concentrations of total lipid, cholesterol and triglyceride in the serum were significantly inhibited. The decrease of the concentrations of creatinine and uric acid in the serum were also observed significantly. 3. In the Dohongsamultang group as compared to the Control, the increase of the amount of protein and glucose of the 24 hours urine induced by PAN were significantly inhibited, and the concentrations of total protein and albumin in the serum were increased significantly. The concentrations of total lipid, cholesterol and triglyceride in the serum were decreased significantly. The decrease of the concentrations of creatinine and uric acid in the serum were observed significantly. It can be inferred that Geumguesingitang has effects on improving proteinuria, hypoproteinemia effectively. It has an effect on hyperlipidemia significantly relieved. And relieving azotemia when nephrotic syndrome is accompanied by the acute renal failure. It can be inferred that Dohongsamultang improves hyperlipidemia effectively.

This study was performed to investigate the urinary methyl hippuric acid (UMHA) excretion among aircraft maintenance workers exposed to xylene by examination of blood test, urine test and biochemical tests. Study subjects (301) were divided into 2 groups; non-exposed group (n=123, who were not exposed to xylene), and exposed group (n=178, who were exposed to xylene). The average of blood level and MHA level was normal. The ${\gamma}$-GTP level was 35.5 IU/L (45.7%) in the exposed group and 27.9 IU/L (44.7%) in the non-exposed (control) group. The proportion of total cholesterol (TG) level higher than 150 mg/dl were 34.3% in the exposed group and 21.1% in the non-exposed group. These results were showed statistically significant difference (${\chi}^2$ = 6.10, P<0.05). Other items showed no statistically significant differences. The results of urine tests were no statistically significant differences in protein, occult blood and glucose level.

Thirteen healthy control, 13 pre-eclamptic, 7 diabetic(DM) and 12 gestational diabetic(GDM) pregnant women participated in a study ofthe interrelationships between the levels of protein, calcium, magnesium, phosphorus, zinc and copper in urine. Urinary protein, magnesium and copper levels were significantly higher (p<0.0005, p<0.0003, p<0.005 respectively) in pre-eclamptic women than those of control, DM and GDM women. Urinary zinc excretion in pre-eclamptic women (1.61 mg/g creatinine) was higher than that of DM women (0.81mg/g creatinine); urinary zinc losses of control and GDM women were wre between the other two rups. The GDM women excreted significantly ore phosphorus in their urine in comparison to control and preeclamptic women (p<0.02), but this was not seen in DM women. Among the DM women, urinary protein excretion was positively correlated with glycosylated hemoglobin(r=0.940) and fasting blood glucose concentration (r=0.889). Urinary zinc excretion also was correlated with glycosylated hemoglobin (r=0.853) and fasting blood glucose (r=0.956). In the GDM and pre-eclamptic women there were also significant correlations between urinar calcium and magnesium (r=0.857, r=0.749 respectively) and between urinary protein and copper(r=0.638, r=0.778 respectively).

Deoxynivalenol (DON), a Fusarium mycotoxin, causes health hazards for both humans and livestock. Therefore, the aim of this study was to investigate the metabolic profiles of the liver, serum, and urine of piglets fed DON using proton nuclear magnetic resonance ($^1H-NMR$) spectroscopy. The $^1H-NMR$ spectra of the liver, serum, and urine samples of the piglets provided with feed containing 8 mg DON/kg for 4 weeks were aligned and identified using the icoshift algorithm of MATLAB $R^2013b$. The data were analyzed by multivariate analysis and by MetaboAnalyst 4.0. The DON-treated groups exhibited discriminating metabolites in the three different sample types. Metabolic profiling by $^1H-NMR$ spectroscopy revealed potential metabolites including lactate, glucose, taurine, alanine, glycine, glutamate, creatine, and glutamine upon mycotoxin exposure (variable importance in the projection, VIP > 1). Forty-six metabolites selected from the principal component analysis (PCA) helped to predict sixty-five pathways in the DON-treated piglets using metabolite sets containing at least two compounds. The DON treatment catalyzed the citrate synthase reactions which led to an increase in the acetate and a decrease in the glucose concentrations. Therefore, our findings suggest that glyceraldehyde-3-phosphate dehydrogenase, citrate synthase, ATP synthase, and pyruvate carboxylase should be considered important in piglets fed DON contaminated feed. Metabolomics analysis could be a powerful method for the discovery of novel indicators underlying mycotoxin treatments.

For quantitative measurement of reflected light from a clinical diagnostic strip, a prototype old reflectance photometer was designed. The strip loader and cassette were made to obtain more accurate reflectance parameters. The strip was illuminated at 45˚c through optical fiber and the intensity of reflected light was determined at rectanguLat angle using a photodiode. The kubelka-munk coefficient and reflection optical density were determined ar four different wavelengths(500, 550, 570 and 610nm) for blood glucose strip. For higher concentration than 300mg/41 about glucose, a saturation state of abforbance was observed at 500, 550 and 570nm. The correlation between glucose concentration and parameters was the best at 610nm.

Background: Garlic and its constituents are reported to have been effective in reducing methane emission and also influence glucose metabolism in body; however, studies in ruminants using garlic leaves are scarce. Garlic leaves contain similar compounds as garlic bulbs, but are discarded in field after garlic bulb harvest. We speculate that feeding garlic leaves might show similar effect as garlic constituents in sheep and could be potential animal feed supplement. Thus, we examined the effect of freeze dried garlic leaves (FDGL) on rumen fermentation, methane emission, plasma glucose kinetics and nitrogen utilization in sheep. Methods: Six sheep were fed Control diet (mixed hay and concentrate (60:40)) or FDGL diet (Control diet supplemented with FDGL at 2.5 g/kg $BW^{0.75}$ of sheep) using a crossover design. Methane gas emission was measured using open-circuit respiratory chamber. Plasma glucose turnover rate was measured using isotope dilution technique of [$U-^{13}C$]glucose. Rumen fluid, feces and urine were collected to measure rumen fermentation characteristics and nitrogen utilization. Result: No significant difference in rumen fermentation parameters was noticed except for rumen ammonia tended to be higher (0.05 < P < 0.1) in FDGL diet. Methane emission per kg dry matter ingested and methane emission per kg dry matter digested were lower (P < 0.05) in FDGL diet. Plasma glucose concentration was similar between diets and plasma glucose turnover rate tended to be higher in FDGL diet (0.05 < P < 0.1). Nitrogen retention was higher (P < 0.05) and microbial nitrogen supply tended to be higher (0.05 < P < 0.1) in FDGL diet. Conclusion: FDGL diet did not impair rumen fermentation, improved nitrogen retention; while absence of significant results in reduction of methane emission, glucose turnover rate and microbial nitrogen supply, further studies at higher dose would be necessary to conclude the merit of FDGL as supplement in ruminant feedstuff.
