  • BACKGROUND/OBJECTIVES: The immigrant population has grown considerably in South Korea since the early 1990s due to international marriages. Dietary changes in immigrants are an important issue, because they are related to health and disease patterns. This study was conducted to compare changes in dietary intake between baseline and follow-up periods. SUBJECTS/METHODS: Two hundreds thirty three Vietnamese female married immigrants. Baseline data were collected during 2006-2009, and the follow-up data were collected during 2008 and 2010. Food consumption was assessed using a 1-day 24-hour recall. RESULTS: The amount of the total food consumed (P < 0.001) including that of cereals (P = 0.004), vegetables (P = 0.003), and fruits (P = 0.002) decreased at follow-up compared to that at baseline, whereas consumption of milk and dairy products increased (P = 0.004). Accordingly, the overall energy and nutrient intake decreased at follow-up, including carbohydrates (P = 0.012), protein (P = 0.021), fiber (P = 0.008), iron (P = 0.009), zinc (P = 0.006), and folate (P = 0.002). Among various anthropometric and biochemical variables, mean skeletal muscle mass decreased (P = 0.012), plasma high density lipoprotein-cholesterol increased, (P = 0.020) and high sensitivity C-reactive protein decreased at follow-up (P < 0.001). CONCLUSIONS: A long-term follow-up study is needed to investigate the association between changes in food and nutrient intake and anthropometric and biochemical variables in these Vietnamese female marriage immigrants.

  • Purpose: The purpose of this study is to estimate the prevalence of the metabolic syndrome in pre-menopausal housewives and to explore controllable and uncontrollable factors regarding metabolic syndrome. Methods: The study population of this cross-sectional survey was from the Korean Health and Nutrition Examination Survey (KHANES) 2010 through 2015, including the fifth and sixth population-based studies. The criteria for metabolic syndrome include waist circumference, blood pressure, fasting plasma glucose, triglyceride, high-density lipoprotein (HDL) based on Korean Clinical Practice Guideline for Metabolic Syndrome by the Korean Academy of Family Medicine 2015. Results: Among the 2,498 subjects, 247 subjects had metabolic syndrome and the prevalence was estimated to be 9.9%. The number of subjects who met the criterion of HDL was 936 (36.2%), which was the most prevalent among the criteria for metabolic syndrome. Statistically significant (p<.05) factors include age, livinghood benefit group, perceived health status, obesity, family history of DM, sleeping time, awareness of stress,leukocyte, and erythrocyte count. The odds ratio of obesity in the BMI ${\geq}25$ group was 12.59 times as high as that of the BMI <25 group (p<.001) for metabolic syndrome. Conclusion: The prevalence of metabolic syndrome in pre-menopausal housewives in the survey was not low, and it is necessary to develop and apply comprehensive health habit management programs to improve controllable factors including exercise and food intake.

  • Atherosclerosis is emerging as one of the major causes of death in Korea as well as Western societies. In the present study; hypocholesterolemic and antiatherogenic effects of the ethanol extract of Allium victorialis Makino was investigated using the conventional rabbit and the cholesteryl ester transfer protein (CETP)-transgenic mouse model. Hypercholesterolemia was induced by feeding high cholesterol diet to the animals for 30 days and they were then fed with high cholesterol diet containing 0.5% of the A. victorialis extract for additional 30 (or 40) days. In the experiment using rabbits, treatment with the A. victorialis extract significantly decreased plasma total cholesterol, low density lipoprotein (LDL)-cholesterol, triglyceride levels and lipid peroxidation compared to those in the control group. Total cholesterol contents in the liver and the heart were also significantly decreased. Lipid staining of the aorta isolated from the rabbits showed that treatment with the A. victorialis extract decreased formation of atheromatous plaques on the intima of the aorta. In the experiment employing CETP transgenic mouse model, treatment with the A. victorialis extract decreased the levels of plasma total cholesterol and the tissue triglyceride levels in the heart. These results demonstrated that the ethanol extract of A. victorialis lowered serum cholesterol levels, tissue lipid contents and accumulation of cholesterol in the artery.

  • Lycopene is the red-coloured carotenoid predominantly found in tomato fruit and one of the major carotenoids in the diets of North American and Europeans. Interest in lycopene is growing rapidly following the recent publication of its effects as a natural antioxidant and prevention of cardiovascular disease and cancers. Lycopene, a polyene hydrocarbon carotenoid haying 13 double bond, of which 11 are conjugated double bonds in a linear array exhibits a strong antioxidant property almost twice as strong as that of ${\beta}$-carotene. Lycopene has been shown in recent epidemiological and experimental studies to protect against oxidative damage of DNA which plays an important part in development of various cancer. Lycopene also contribute towards reducing the risk of cardiovascular diseases by preventing oxidation of low-density lipoprotein(LDL) cholesterol. This review summarize our knowledge and the current understanding of lycopene in human health as well as the results of experiments we conducted. We conducted experiments for investigating the effects of antioxidant in broiler and the possibilities of production of high quality eggs containing lycopene by the dietary lycopene supplementation with synthetic lycopene or tomato paste. The results shows that thiobarbituric acid reaction substances(TBARS) values in process of LDL oxidation in blood serum of broiler were significantly decreased by dietary lycopene and tomato paste. The dietary lycopene supplementation resulted in improved egg yolk color and in decreased the malondialdehyde (MDA) of egg yolk after 4 wk of storage at room temperature significantly(P<0.05). The dietary tomato paste was more effective in the MDA reduction compared to the lycopene(P<0.05). The contents of lycopene in egg yolk of the lycopene supplementation groups were significantly higher than those of the control group.

  • Introduction: There is epidemiological evidence indicating that the metabolic syndrome increases the risk of colorectal cancer. Since there is little information about this issue in Iran, the present study was conducted to evaluate prevalence of metabolic syndrome and its components in patients with colorectal cancer. Material and Methods: This cross-sectional survey involved 200 patients with a new diagnosis of colorectal cancer. Demographic information of patients was collected through the interview with them. Components of metabolic syndrome including fasting glucose serum, triglyceride, high density lipoprotein, blood pressure and waist circumference were measured for all of the patients. Results: A total of 72 colorectal cancer patients (36%) met metabolic syndrome criteria with rates of 76% for women and 24% for men. BMI in metabolic syndrome patients was higher than other colorectal cancer patients. Disease history including hypertension, diabetes and cardiovascular disease was most frequent in metabolic syndrome patients. Pathological characteristics of colorectal cancer were not significantly associated with the disease. Conclusion: The findings of present study indicated that the prevalence of metabolic syndrome in CRC patients is relatively high. Therefore, further analytical and multi centric studies are needed to better understand the role of metabolic syndrome in development of CRC in Iran. If this association is confirmed in future studies, metabolic syndrome patients should be considered in CRC screening programs.

  • This study investigated the hypothesis that a sorghum extract exerts anti-diabetic effects through a mechanism that improves insulin sensitivity via peroxisome proliferator-activated receptor gamma (PPAR-${\gamma}$) from adipose tissue. Seven C57BL/6 mice were fed an AIN-93M diet with fat consisting of 10% of total energy intake (LF) for 14 weeks, and 21 mice were fed a high-fat AIN diet with 60% of calories derived from fat (HF). From week 8, the HF diet-fed mice were orally administered either saline (HF group), 0.5% (0.5% SE group), or 1% sorghum extract (1% SE group) for 6 weeks (n = 7/group). Perirenal fat content was significantly lower in the 0.5% SE and 1% SE groups than that in the HF mice. Levels of total and low-density lipoprotein cholesterol, triglycerides, glucose, and the area under the curve for glucose were significantly lower in mice administered 0.5% SE and 1% SE than those in HF mice. Serum insulin level was significantly lower in mice administered 1% SE than that in HF mice or those given 0.5% SE. PPAR-${\gamma}$ expression was significantly higher, whereas the expression of tumor necrosis factor-${\alpha}$ was significantly lower in mice given 1% SE compared to those in the HF mice. Adiponectin expression was also significantly higher in mice given 0.5% SE and 1% SE than that in the HF mice. These results suggest that the hypoglycemic effect of SE may be related with the regulation of PPAR-${\gamma}$-mediated metabolism in this mouse model.

  • Background: In order to assess the high value-added use of the alginate-free residue of sea tangle, an animal study was performed to evaluate the functional activities and key compounds present. In the animal study, sea tangle and the alginate-free residue demonstrated good anti-hyperlipidemic and anti-arteriosclerotic abilities. Results: The functional compounds in the alginate-free residue of the sea tangle were effectively extracted by supercritical fluid extraction (SFE). The optimum extraction temperature and pressure were 40 ℃ and 6500 psi (M1) in the SFE, a better method in comparison to the conditions of 70 ℃ and 4500 psi (M2), respectively. The anti-atherosclerotic effects of the alginate-free residue of sea tangle (M1, M2) were investigated in Sprague-Dawley rats treated with poloxamer 407, Triton WR 1339, corn oil, and a high-fat diet. The M1 fraction reduced the serum lipid levels with greater efficacy than the M2 fraction. In the hyperlipidemic rats, treatment with M1 decreased the serum triglyceride (TG), total cholesterol (TC), and low-density lipoprotein-cholesterol (LDL-C) levels when compared to the levels in normal rats. Conclusion: Our results demonstrated that the alginate-free residue of sea tangle reduces serum TC, TG, and LDL-C. These results suggest that the alginate-free residue of sea tangle contains physiologically active components, such as fucosterol, that may exert beneficial effects in the prevention of atherosclerosis.

  • The metabolic syndrome, by definition, is not a disease but is a clustering of individual metabolic risk factors including abdominal obesity, hyperglycemia, hypertriglyceridemia, hypertension, and low high-density lipoprotein cholesterol levels. These risk factors could dramatically increase the prevalence of type 2 diabetes and cardiovascular disease. The reported prevalence of the metabolic syndrome varies, greatly depending on the definition used, gender, age, socioeconomic status, and the ethnic background of study cohorts. Clinical and epidemiological studies have clearly demonstrated that the metabolic syndrome starts with central obesity. Because the prevalence of obesity has doubly increased worldwide over the past 30 years, the prevalence of the metabolic syndrome has markedly boosted in parallel. Therefore, obesity has been recognized as the leading cause for the metabolic syndrome since it is strongly associated with all metabolic risk factors. High prevalence of the metabolic syndrome is not unique to the USA and Europe and it is also increasing in most Asian countries. Insulin resistance has elucidated most, if not all, of the pathophysiology of the metabolic syndrome because it contributes to hyperglycemia. Furthermore, a major contributor to the development of insulin resistance is an overabundance of circulating fatty acids. Plasma fatty acids are derived mainly from the triglycerides stored in adipose tissues, which are released through the action of the cyclic AMP-dependent enzyme, hormone sensitive lipase. This review summarizes the latest concepts in the definition, pathogenesis, pathophysiology, and diagnosis of the metabolic syndrome, as well as its preventive measures and therapeutic strategies in children and adolescents.

  • Increased oxidative stress in obese diabetes may have causal effects on diabetic complications, including dyslipidemia. Lipopolysccharides (LPS) along with an atherogenic diet have been found to increase oxidative stress and insulin resistance. Cranberry has been recognized as having beneficial effects on diseases related to oxidative stress. Therefore, we employed obese diabetic animals treated with an atherogenic diet and LPS, with the aim of examining the effects of cranberry powder (CP) on diabetic related metabolic conditions, including lipid profiles, serum insulin and glucose, and biomarkers of oxidative stress. Forty C57BL/KsJ-db/db mice were divided into the following five groups: normal diet + saline, atherogenic diet + saline, atherogenic diet + LPS, atherogenic diet + 5% CP + LPS, and atherogenic diet + 10% CP + LPS. Consumption of an atherogenic diet resulted in elevation of serum total cholesterol and atherogenic index (AI) and reduction of high density lipoprotein (HDL)-cholesterol. However, with 10% CP, the increase in mean HDL-cholesterol level was close to that of the group with a normal diet, whereas AI was maintained at a higher level than that of the group with a normal diet. LPS induced elevated serum insulin level was lowered by greater than 60% with CP (P < 0.05), and mean serum glucose level was reduced by approximately 19% with 5% CP (P > 0.05). Mean activity of liver cytosolic glutathione peroxidase was significantly increased by LPS injection, however it was reduced back to the value without LPS when the diet was fortified with 10% CP (P < 0.05). In groups with CP, a reduction in mean levels of serum protein carbonyl tended to occur in a dose dependent manner. Particularly with 10% CP, a reduction of approximately 89% was observed (P > 0.05). Overall results suggest that fortification of the atherogenic diet with CP may have potential health benefits for obese diabetes with high oxidative stress, by modulation of physical conditions, including some biomarkers of oxidative stress.

  • Objectives : This study investigated the hepatoprotective effect of herbal mixture including Lycii fructus (HML) in thioacetamide (TAA)-induced hepatotoxicity in mice. Methods : To confirm the liver protective effect, induced by TAA for 3 days injection at 100 mg/kg mice, HML were treated for 8 weeks at 300 mg/kg/day, 1000 mg/kg/day. Positive control was treated silymarin 50 mg/kg/day after TAA injection. The changes of mortality rate, clinical signs, organ weight, relative liver, blood chemistry and histopathological findings were analyzed after experiment. Results : Body weight gain was observed in all groups, but TAA treated group at 4th week and all treated groups decreased weight compared to the untreated group. As a result of organ weight measurement, organ weight gain due to hepatic injury was observed statistically significantly in TAA-treated group and TAA+Silymarin treated group, and the herbal mixture-treated group showed a tendency to decrease compared to the TAA treated group. Blood biochemistry showed that total cholesterol and very low density lipoprotein cholesterol decreased statistically in TAA+low-dose and high dose herbal mixture treated group compared to the TAA-treated group. Histopathological examination showed that liver abnormalities were not observed in untreated group, liver fibrosis was observed in liver injury with TAA treated and herbal mixture treated group. And, TAA+high dose herbal mixture group showed relaxation tendency on liver calcification compared to the TAA treated group. Conclusions : According to the above results, HML provided hepatoprotective effects on the hepatic injury by reduction of inflammatory responses.
