Objectives: Metabolic syndrome is a cluster of risk factors for type 2 diabetes mellitus and cardiovascular disease. Associations between metabolic syndrome and several types of cancer have recently been documented. Methods: We analyzed the sample cohort data from the Korean National Health Insurance Service from 2002, with a follow-up period extending to 2013. The cohort data included 99 565 individuals who participated in the health examination program and whose data were therefore present in the cohort database. The metabolic risk profile of each participant was assessed based on obesity, high serum glucose and total cholesterol levels, and high blood pressure. The occurrence of cancer was identified using Korean National Health Insurance claims data. Hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated using Cox proportional hazards models, adjusting for age group, smoking status, alcohol intake, and regular exercise. Results: A total of 5937 cases of cancer occurred during a mean follow-up period of 10.4 years. In men with a high-risk metabolic profile, the risk of colon cancer was elevated (HR, 1.40; 95% CI, 1.14 to 1.71). In women, a high-risk metabolic profile was associated with a significantly increased risk of gallbladder and biliary tract cancer (HR, 2.05; 95% CI, 1.24 to 3.42). Non-significantly increased risks were observed in men for pharynx, larynx, rectum, and kidney cancer, and in women for colon, liver, breast, and ovarian cancer. Conclusions: The findings of this study support the previously suggested association between metabolic syndrome and the risk of several cancers. A high-risk metabolic profile may be an important risk factor for colon cancer in Korean men and gallbladder and biliary tract cancer in Korean women.

Objectives: Reactive Oxygen Species(ROS) are continuously produced at a high rate as a by-product of aerobic metabolism. Since tissue damage by free radical, ROS such as hydrogen peroxide($H_2O_2$), nitric oxide(NO) increases with age. Several lines of evidence provided that ROS appears to cause to develop aging-related various diseases such as cancer, arthritis, cardiovascular disease. In this study, we have conducted to investigate the pharmacological effects of red ginseng for the development possibility to pharmacopuncture drug sources or healthy aid foods. Methods: For our aims, it was investigated the biological activities of Red Ginseng ethanol extracts (RGEE) by measuring total polyphenol contents, total flavonoid contents, DPPH radical scavenging activity, ABTS radical scavenging activity and cell viability of MCF 10A and SK-MEL-2 in vitro with MTT assay method. Results: The total polyphenol contents of RGEE was 3.06${\pm}$0.11mg/g in 10mg/ml, the total flavonoid contents of RGEE was 1.35${\pm}$0.01mg/g in same concentration. The ABTS radical scavenging activity was about 80% and that of DPPH activity was 65% in 50mg/ml of RGEE. The cell viability of SKMEL-2, skin cancer cell line was decreased and that of MCF 10A, skin normal cell line was increased. Conclusions: We conclude that RGEE may be useful as potential functional foods or pharmacopuncture drug sources on the diseases induced by oxidant stress.

This study was carried out to estimate the relationship among dietary intakes, blood levels, and urinary excretions of Ca, P, Mg and serum lipid levels in 30 healthy adults living area of Korea(12males and 18 females). Analyses for the nutritional status of the subjects were performed by 3-day dietary intake record, duplicated diet collection, 24-hours urine collection, and venous blood sampling before anthropometry. The mean daily intakes of Ca, P and Mg estimated for 3 days were 452.5$\pm$159.5mg, 725.6$\pm$ 567.8mg and 240.4$\pm$78.5mg and the serum concentrations of Ca, P and Mg were 8.9$\pm$ 0.5mg / dl, 3.3$\pm$0.6mg / dl, and 2.1$\pm$0.8mg /dl, respectively. The 24-hour urinary excretions of Ca, P and Mg were 80.4$\pm$24.0mg, 399.0$\pm$161.1mg and 64.8$\pm$35.3mg, respectively. The serum concentrations of total cholesterol, triglyceride, HDL-cholesterol, LDL-cholesterol were 158.8$\pm$32.9mg/dl, 95.6$\pm$43.9mg/dl, 45.7$\pm$9.9mg/dl and 92.2$\pm$ 28.5mg/dl, respectively. In the relation between Ca, P, Mg and serum lipids it showed positive correlation with serum Ca and HDL-cholesterol at the level of significance of 5%. It can be concluded that the high level of Ca in serum may be useful in the prevention of cardiovascular disease, but the study verifies the need for more systematic studies.

Obesity is especially a serious health problem in industrialized countries, because it is considered to be a risk factor associated with the genesis or development of various metabolic diseases, including cardiovascular disease and type 2 diabetes mellitus. The purpose of this study was to investigate the effects of tanshinone IIA from Salvia miltiorrhiza Bunge on induction of apoptossis and inhibition of adipogenesis in in 3T3-L1 preadipocytes and adipocytes. The results demonstrated that tanshinone IIA decreased cell population growth of 3T3-L1 preadipocytes, assessed with the MTT [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide] and LDH (lactate dehydrogenase) assay. Flow cytometric analysis of 3T3-L1 preadipocytes exposed to tanshinone IIA showed that apoptotic cells increased in a timeand dose-dependent manner. Treatment with tanshinone IIA decreased the number of normal cells and increased the number of apoptotic cells in a dose-dependent manner. The induction of apoptosis in 3T3-L1 preadipocytes by tanshinone IIA was mediated through the activation of caspase-3 and Bax, and then through the cleavage of PARP and the down-regulation of Bcl-2. Moreover, tanshinone IIA significantly decreased the amount of intracellular triglycerides and GPDH (glycerol-3-phosphate dehydrogenase) activity in 3T3-L1 adipocytes. Our results suggest that tanshinone IIA efficiently induces apoptosis and inhibits adipogenesis in 3T3-L1 preadipocytes and adipocytes.

Hypertension is the major risk factor for cardiovascular disease which is considered the leading cause of death in Korea. Since nonpharmarologic dietary intervention is recommended as the first step in the management of hypertension, evaluation of intervention programs is needed to formulate strategies for improving patients' dietary adherence. This study was designed to evaluate the overall effectiveness of a hypertension nutrition education program (HNEP) at a public health center, by assessing changes in nutrition knowledge, food attitude, self-efficacy, dietary behavior, and nutrient intake after program completion. An HNEP was conducted in Suwon city for 5 months in 1999 by a public health center. The program provided 3 sessions of group education with individual nutrition counseling. Thirty-five patients participated fully in the program out of 62 enrollees. Data about nutrition knowledge, food attitude, self-efficacy, dietary behavior, and intake (24-hour recall) were collected before (baseline) and after the program. Post program results indicate the following : 1) nutrition knowledge and perception of importance of nutrition significantly increased, 2) food attitudes also improved, 3) the self-efficacy for maintaining a low salt diet was increased significantly, whereas self-efficacy for maintaining a low fat diet or dietary guidelines was not improved, 4) frequency of intake of processed food, animal fat, and sweets as well as frequency of dining out were significantly reduced, 5) nutrient intake was not improved after the program, 6) the most serious barrier for participating in the program and practicing diet therapy was lack of time and willingness. In conclusion, it appears that HNEP might improve food attitudes, individual perceptions and self-efficacy for desirable eating behavior, but it might not improve dietary intake. It follows then, that a long term intervention program may need to increase effectiveness of patient dietary adherence.

Resveratrol, or its glycoside form piceid, is a dietary antioxidant polyphenolic compound, found in grapes and red wine that has been shown to have protective effects against cardiovascular disease. However, very low water solubility of the compound may limit its application in the food and pharmaceutical industries. The amylosucrase (AMAS) of Alteromonas macleodii Deep ecotype was expressed in Escherichia coli and showed high glycosyltransferase activity to produce the glucosyl piceid when piceid was used as an acceptor. The conversion yield of piceid glucoside was 35.2%. Biotransformation using culture of the E. coli harboring the amas gene increased the yield up to 70.8%. The transfer product was purified by reverse phase chromatography and recycling preparative HPLC, and the molecular structure of the piceid glucoside was determined using NMR spectroscopy. The piceid glucoside was identified as glucosyl-${\alpha}$-($1{\rightarrow}4$)-piceid. The solubility of glucosyl piceid was 5.26 and 1.14 times higher than those of resveratrol and piceid, respectively. It is anticipated that dietary intake of this compound is more effective by enhancing the bioavailability of resveratrol in the human body because of its hydrophilic properties in the intestinal fluid.

Cow's milk and dairy products are elements of the human diet that could play an important role in improving human health. The macronutrients and micronutrients found in milk could supply the nutrients required to maintain human health. Among them, milk-derived bioactive peptides have been identified as potential ingredients found in health promoting functional foods. These bioactive peptides target diet-related chronic diseases, particularly non-communicable ones such as cardiovascular disease, diabetes and obesity. Additionally probiotics such as lactic acid bacteria (LAB) are can be considered live microorganisms that confer health benefits for the host-, when administered in adequate amounts. Further, the calcium, vitamin D, and protein content of milk and dairy products could play a role in proving bone health. The effect of milk and calcium on bone mineral density could prevent against fracture, osteoporosis and rickets. Furthermore, milk and dairy products also contain which factors that, which protect against dental caries (anti-cariogenic properties). This paper reviews the various nutritional functions of milk and dairy products in improving human health.

Platelet aggregation is a complex phenomenon that probably involves several intracellular biochemical pathways. When activated, platelets change shape, aggregate and release the contents of their intracellular granules. The interactions between platelets and blood vessel walls are important in the development of thrombosis and cardiovascular diseases. When blood vessels are damaged, platelet aggregation occurs rapidly to form haemostatic Plugs or arterial thrombi at the sites of vessel injury or in regions where blood flow is disturbed. These thrombi are the source of thromboembolic complications of atherosclerosis, heart attacks, stroke, and peripheral vascular disease. Therefore, the inhibition of platelet function represents a promising approach for the prevention of thrombosis. Plants constitute a rich source of bioactive chemicals such as phenolics, terpenoids and alkaloids. Plant extracts may be an alternative to currently used medicinal source because they constitute a rich source of bioactive chemicals. This study was performed to investigate the antiplatelet activity of extract of Tabebuia impetiginosa Martius ex DC (Taheebo) and find out which fractions to this activity in rabbit platelet. Taheebo was methanol extracted and solvent fractionated in to five fractions (hexane, chloroform, ethylacetate, butanol and water). And each fractions were investigated inhibitory effects on platelet aggregation induced by various agonists using washed rabbit platelets in vitro.

Background: Previous research has shown that paramedics are exposed to risks in the form of injuries to the musculoskeletal system. In addition, there are studies showing that they are also at increased risk of cardiovascular disease, cancer, and psychiatric diseases, which can partly be explained by their constant exposure to stress. The aim of this study is to evaluate whether the use of shoulder straps decreases physical effort in the form of decreased heart rate and cortisol concentration. Methods: A stretcher with a dummy was carried by 20 participants for 400 m on two occasions, one with and one without the shoulder straps. Heart rate was monitored continuously and cortisol samples were taken at intervals of 0 minutes, 15 minutes, 30 minutes, 45 minutes, and 60 minutes. Each participant was her or his own control. Results: A significant decrease in heart rate and cortisol concentration was seen when shoulder straps were used. The median values for men (with shoulder straps) at 0 minutes was 78 bpm/21.1 nmol/L (heart rate/cortisol concentration), at 15 minutes was 85 bpm/16.9 nmol/L, and at 60 minutes was 76 bpm/15.7 nmol/L; for men without shoulder straps, these values were 78 bpm/21.9 nmol/L, 93 bpm/21.9 nmol/L, and 73 bpm/20.5 nmol/L. For women, the values were 85 bpm/23.3 nmol/L, 92 bpm/20.8 nmol/L, and 70 bpm/18.4 nmol/L and 84 bpm/32.4 nmol/L, 100 bpm/32.5 nmol/L, and 75 bpm/25.2 nmol/L, respectively. Conclusion: The use of shoulder straps decreases measurable physical stress and should therefore be implemented when heavy equipment or a stretcher needs to be carried. An easy way to ensure that staff use these or similar lifting aids is to provide them with personalized, well-adapted shoulder straps. Another better option would be to routinely sewn these straps into the staff's personal alarm jackets so they are always in place and ready to be used.
