This study was conducted to investigate correlation between soybean and their products consumption and risk factors for atherosclerosis in the healthyKorean adults. Health behaviors such as smoking, exercise, alcohol consumption and dietary patterns and nutrient intakes of 193 healthy adult subjects aged from 26 to 69 were assessed by using interview and semiquantitative food frequency questionnaire. The BMI, blood pressure and biochemical parameters of blood were examined as well as preferences for taste and family history of disease. Data were expressed as quartile according to soybean and their products consumption. The average daily soybean and their product consumption for 1st, 2nd, 3rd, and 4th percentile group were 36, 78, 112, and 182g, respectively. The more consumption of soybean and their products, the more intake of energy, protein, lipid, fiber, Ca, cholesterol as well as frequency of exercise, smoking and drinking. Serum TG, total cholesterol and LDL-cholesterol and AI as risk factors of atherosclerosis were positively correlated with smoking and drinking (p<0.05). Especially, serum TG was positively correlated with hypertension and BMI (p<0.01). But, no correlation between exercise, salty taste, meat preference, soybean products consumption and atherosclerosis risk factors was found, which means that life styles such as smoking and drinking rather than dietary habits might influence atherosclerosis in healthy adults. In conclusion, present soy products consumption should be increased by way of developing new generation soy products in order to exert anti-atherosclerotic effect by soybean in human.

The in vitro antibacterial activity of DWP20418 (1R, 5S, 6S)-6-[1-(R)-Hydroxyethyl)-l-methyl-2-[(2S,4S)-2-(piperazinylcarbonyl)-1-(R)-hydroxyethyl)pyrrolidine-4-thio]carb apen-2-em-3-carboxylic acid), a new carbapenem antibiotic, was compared with those of imipenem (IPM) and meropenem (MEPM). DWP20418 was comparable or slightly more superior to MEPM against gram-positive bacteria, and it showed more potent activity to IPM against gram-negative bacteria. DWP20418 was particularly active against MRSA, and its $MIC_{90}$ of methicillin-susceptible S. aureus, low methicillin-resistant S. aureus and high methicillin-resistant S. aureus were 0.391, 25 and 50 ${\mu}g/ml$, respectively. With a view of $MIC_{90}$, DWP20418 was comparable than the other carbapenems against P. aeruginosa and E. coli isolates. The activity of DWP20418 was not affected in the presence of $Mg^{2+},\;Ca^{2+}$ or horse serum. But inoculum size and alterations in pH of medium affected its antibacterial activity. DWP20418 showed rapidly bactericidal activity within 1h, and regrowth was not observed even incubation of 24hrs at the concentrations near the MIC.

The large amount of tissue culture medium (TCM), which contains some of the active secretory components of Korean wild ginseng (KWG; Panax ginseng) such as saponins, is usually discarded after harvest of KWG. The present study was aimed to investigate the efficacy of oral administration of the TCM-KWG on growth performance and diseases resistance in broiler chickens. A day old broiler chickens randomized in 6 groups (n = 60/groups) were administered orally with 0, 2, 4, 8, 16 and 32 mL/L TCMKWG through drinking water for 5 weeks and examined the change of weight gain, feed intake and blood components. Also, five weeks old broiler chickens (n = 15/groups) were challenged orally with Salmonella (S.) gallinarum and investigated the mortality in broiler chickens. An average weight gain and feed intake significantly didn't change in TCM-KWG administration groups as compared to control group. The concentration of calcium (Ca), phosphate (Pi) and potassium (K) in serum were increase by TCM-KWG administration in broiler chickens. We also found that oral administration of TCM-KWG through drinking water significantly reduced the mortality in broiler chickens experimentally infected with virulent S. gallinarum. The results of this study indicated that TCM-KWG administration may elevate the resistance on disease and improved the skeleton formation and body homeostasis of chickens, and TCM-KWG can be used as a cost-effective and environmentally alternative additives to control of the disease and growth.

This paper reports the effects of rare earth nitrate (REN) on the growth of internal organs and mineral elements in serums of broiler chickens. The REN used is mixture of light RE containing mainly La, Ce, Pr and Nd 4 elements. 40 eight-week old AA broiler chickens were divided randomly into four groups that their treatments were respectively 0, 20, 200 and 2000 mg REN/kg feed and the duration of the experiment was 60 days. Responses were measured in terms of internal organic weight and tissue, contents of mineral elements in serums. There were no significant differences between the organ ratios and tissue changes of the 20, 200 mg REN/kg groups and the control group. The organs included the heart, liver, kidneys, lungs, testicles, thyroids, adrenal glands, pancreas, tonsies of caecum, stomachus glandularis, duodenum, ileum and bursa of Fabricius. The liver and thyroid indices of 2000 mg REN/kg group were significantly higher than those of the control group (p < 0.01, p < 0.05) and the adrenal gland index lower (p < 0.05). The pathlolgic changes in the heart, kidney and thyroid were more serious than that of the control group. No significant differences occurred between the contents of K, Na, Mg elements in the serum of all groups, with the exception of the content of Ca, which was higher in the 2000 mg/kg group (p < 0.05). The contents of all trace elements including Mn, Zn and Cu, but except Fe, in the serums of all the treated groups were significantly higher than those of the control group (p < 0.01).

Curcumin is naturally occurring polyphenolic compound found in turmeric and has many pharmacological activities. The present study was undertaken to evaluate anti-allergic inflammatory activity of curcumin, and to investigate its inhibitory mechanisms in immunoglobulin E (IgE)/Ag-induced mouse bone marrow-derived mast cells (BMMCs) and in a mouse model of IgE/Ag-mediated passive systemic anaphylaxis (PSA). Curcumin inhibited cyclooxygenase-2 (COX-2) dependent prostaglandin $D_2$ ($PGD_2$) and 5-lipoxygenase (5-LO) dependent leukotriene $C_4$ ($LTC_4$) generation dose-dependently in BMMCs. To probe the mechanism involved, we assessed the effects of curcumin on the phosphorylation of Syk and its downstream signal molecules. Curcumin inhibited intracellular $Ca^{2+}$ influx via phospholipase $C{\gamma}1$ ($PLC{\gamma}1$) activation and the phosphorylation of mitogen-activated protein kinases (MAPKs) and the nuclear factor-${\kappa}B$ (NF-${\kappa}B$) pathway. Furthermore, the oral administration of curcumin significantly attenuated IgE/Ag-induced PSA, as determined by serum $LTC_4$, $PGD_2$, and histamine levels. Taken together, this study shows that curcumin offers a basis for drug development for the treatment of allergic inflammatory diseases.

This study was designed to observe the effects of edible mugwort and medicinal mugwort ( Ganghwa medicinal mugwort) on blood components of rats. Eighteen young rats of Sprague Dawley strain that weighted 84${\pm}$9g, were used in this study. They were fed on the basal diet(control diet). 5% edible mugwort powder(EM diet) and 5% medicinal mugwort(MM diet) for 4 weeks respectively. In proximate composition of mugworts, crude protein and crude ash contents of EM were 2% higher than those of MM. Mn, Zn and vitamin A contents of EM were 3 times higher than those of MM, but in Ca content, MM was 5 times higher than that of EM. The contents of albumin and the activity of ALT, AP amylase and CK in serum were significantly increased, but the activity of AST was significantly lowered in EM and MM diet groups. The contents of TG and the activity of LDH were towered in EM diet group and MM diet group resulted in decrease of glucose content and increase of TP content.

The purpose of this study was to confirm that calcium intake and healthy status play a role in reducing the risk of cardiovascular disease, to assure that calcium intake and regular exercise are important in reducing serum lipid levels in middle-aged women. Daily nutrient intakes were analyzed by convenient method. Anthropometric measurement such as body weight and height and blood pressure were measured. The subjects divided into two groups : women in group I under 50 years of age($\leq$49 yr group) and those in group II 50 years up($\geq$50 yr group). Average ages of group I and II were 43.87 and 53.46 years. The nutrients intake of subjects were higher than Korean recommended dietary allowances(KRDA) except calorie, iron, calcium, vitamin B1. They showed significant difference each other in vitamin B2(p<0.05), calcium(p<0.01) intake. Mean daily calcium intake was 540.88mg in $\leq$49 yr group and 519.50mg in $\geq$50 yr group. The levels of serum cholesterol, triglyceride, blood pressure, Atherogenic Index(AI), LDL/HDL and Cardiac Index(CI) were increased with age. The triglyceride and total cholesterol concentrations and LDL/HDL in $\geq$50 yr group were significantly higher than those of $\leq$49 yr group. There was a highly significantly positive correlation between age and triglyceride, total cholesterol and Atherogenic Index(AI). Triglyceride, total cholesterol, LDL-cholesterol concentration and Atherogenic Index(AI) were positively correlated with body weight and WHR(waist-hip ratio). Also ther was a significantly negative correlation between exercise and Cardiac Index(CI). Also a significantly negative correlation was found between Ca intake and LDL-cholesterol. Exercise and Cardiac Index(CI) also had a significantly negative relation. The results suggest that increased habitual physical activity and calcium intake should be recommended as a way of decreasing blood lipids and blood pressure in middle-aged women.

The objective of this study was to investigate the effects of iron supplementation and nutrition education on the iron status and anemia of middle school girls in Ulsan city in Korea. The subjects were already diagnosed as having anemia (hemoglobin < 12 g/dL) or iron deficiency (ferritin < 12 ng/mL and/or transferrin sataturation < 14 %). Over a period of three months, one iron tablet (80 mg Fe as ferrous sulfate/day) was administered to the iron deficient subjects and two tablets (160 mg Fe as ferrous sulfate/day) were administered to the anemia subjects. Total calorie intake of subjects was 82.1 % of RDA. The iron intake of subjects was 91.3 % of RDA and the Ca intake was 78.8 % of RDA. The basal hemoglobin concentration of subjects averaged 12.8 1.2 g/dL, and this increased significantly (p < 0.001) to 13.2 0.9 g/dL after iron supplementation. The basal ferritin concentrations were 14.9 14.2 ng/mL and these significantly increased to 26.6 19.8 ng/mL (p < 0.001). The level of total iron binding protein (TIBC) significantly decreased from the initial 523.1 108.7 $\mu\textrm{g}$/dL to 462.2 90.2 $\mu\textrm{g}$/dL (p < 0.001) after iron supplementation. Anemia symptoms such as‘Being bruised easily’, ‘Inflamed inner mouth’, and ‘Pale face’ improved significantly after iron supplementation in the subjects. There was a negative correlation between their class & year ranking and serum iron level, transferrin saturation after nutritional education and iron supplementation. It was shown, therefore, that the higher the improvement of their anemia level after iron supplementation, the higher their academic performance. It was shown that there was some improvement of their dietary attitudes after nutritional education, and that their serum level related to anemia symptoms and iron nutrition was improved after iron supplementation.

Objective: To investigate serum 25-hydroxyl vitamin D (25(OH)D) and vitamin D-binding protein (VDBP) concentrations in women with endometriosis according to the severity of disease. Methods: Women with mild endometriosis (n = 9) and advanced endometriosis (n = 7), as well as healthy controls (n = 16), were enrolled in this observational study. Serum total 25(OH)D concentrations were analyzed using the Elecsys vitamin D total kit with the Cobas e602 module. Concentrations of bioavailable and free 25(OH)D were calculated. Concentrations of VDBP were measured using the Human Vitamin D BP Quantikine ELISA kit. Variables were tested for normality and homoscedasticity using the Shapiro-Wilk test and Leven F test, respectively. Correlation analysis was used to identify the variables related to total 25(OH)D and VDBP levels. To assess the effects of total 25(OH)D and VDBP levels in the three groups, multivariate generalized additive modeling (GAM) was performed. Results: Gravidity and parity were significantly different across the three groups. Erythrocyte sedimentation rate (ESR) and CA-125 levels increased as a function of endometriosis severity, respectively (p= 0.051, p= 0.004). The correlation analysis showed that total 25(OH)D levels were positively correlated with gravidity (r = 0.59, p< 0.001) and parity (r = 0.51, p< 0.003). Multivariate GAM showed no significant relationship of total 25(OH)D levels with EMT severity after adjusting for gravidity and ESR. However, the coefficient of total 25(OH)D levels with gravidity was significant (1.87; 95% confidence interval, 0.12-3.63; p= 0.040). Conclusion: These results indicate that vitamin D and VDBP levels were not associated with the severity of endometriosis.

The purpose of this study was to investigate the improvement effect of 5% turmeric (Curcuma longa L.) on the blood glucose and lipid metabolism function of streptozotocin (STZ, 45 mg/kg body weight)-induced diabetic rats. Seven-week-old male rats were divided into four groups (n=6), and fed experimental diets containing turmeric meal [basal diet+5% turmeric (BT), basal diet+STZ+5% turmeric (ST)], and control (BD), BS groups (basal diet+STZ). The results of this study, turmeric diet groups (BT, ST) in lipid component as evidenced from the significantly reduction of serum total cholesterol, low density lipoprotein-cholesterol (LDL-cholesterol), atherosclerotic index (AI), cardiac risk factor (CRF), triglyceride (TG), phospholipid (PL), free cholesterol, cholesteryl ester, uric acid, blood glucose, non esterified fatty acid (NEFA), and elevation of high density lipoprotein-cholesterol (HDL-cholesterol). The serum albumin and globulin contents were increased in turmeric supplementation diet than STZ-induced diabetic rats (p<0.05). Concentrations of sodium (Na) and chlorine (Cl) in sera were lower in the turmeric diet than diabetic group. Total calcium (T-Ca), phosphorus (Pi) and potassium (K) concentrations in sera were higher in the BT, ST and BD groups than BS group. In vivo experiments with Sprague-Dawley rats showed that ingestion of turmeric (Curcuma longa L.) were effective in the blood glucose and lipid metabolism functional improvement.
