Objectives This study was performed to evaluate the relation between hair tissue mineral elements(HTME) and Heart rate variability(HRV) of the metabolic syndrome(MS). Methods 89 persons(41-69 ages) who visited Oriental hospital for medical examination were divided MS group(n=22) and control group(n=67). HTME and HRV were compared, and were analyzed correlation with five contents of the MS. Results (1) In total subjects, waist circumference had a positive correlation with Pb. Blood pressure had a negative correlation with Mg. High density lipoprotein cholesterol(HDL-chol) had a negative correlation with Pb, Sb and K, while positive correlation with Ca/K. Triglyceride(TG) had a negative correlation with Mg and Na/K, while positive correlation with K and Ca/Mg. (2) In total subjects, TG and fasting blood sugar(FBS) had negative correlation with high frequency(HF), while positive correlation with low frequency/high frequency ratio(LF/HF). (3) In MS group, most of the level of toxic minerals were higher, and the level of major nutritional minerals were lower, but there were no statistical signficance. In two groups, there is no contrast between the correlations of the MS contents and HTME. (4) In MS group, HF was significantly lower and LF/HF was higher than normal group. LF/HF had a negative correlation with waist circumference in MS group, while positive correlation in normal group. (5) In total subjects, TP had a positive correlation with Mg. In two groups, there is no contrast between the correlations of the MS contents and HRV. However LF/HF had a positive correlation with Na in MS group, TP and LF had negative correlation with Ca, while RMSSD and HF had negative correlation with Cu in normal group. Conclusion These results may suggest that HTME and HRV are useful in diagnosing and preventing the metabolic syndrome.

Objectives: We investigated the effects of Allii Fistulosi Bulbus (AFB) on high fat diet (HFD)-induced obesity in mice and the regulation of energy metabolism in muscle tissues of mice. Methods: The C57BL/6 mice (6 weeks, male) were fed a HFD for 8 weeks and then administrated with AFB extract at 500 mg/kg (p.o.) once daily for 4 weeks. The body weight (BW), muscle weight, calorie intake, fasting blood glucose (FBG) and serum glucose, insulin, and low-density lipoprotein-cholesterol (LDL-C) levels were measured in mice. It was also observed the histological changes of pancreas, liver, and fat tissues with hematoxylin and eosin staining. It was investigated the phosphorylation of insulin receptor substrate 1 (IRS-1), Ser/Thr kinase (AKT), and adenosine monophosphate-activated protein kinase (AMPK), and the expression of phosphoinositide 3-kinase, glucose transporter type 4 (GLUT4), and sirtuin1 (Sirt1) in gastrocnemius tissues by western blot, respectively. Results: The increases of BWs, calorie intakes and FBG levels in obesity mice were decreased significantly by the administration of AFB extract. The AFB extract administration was reduced significantly serum levels of glucose, insulin, and LDL-C in obesity mice. The AFB extract inhibited lipid accumulation in liver tissues, hyperplasia of pancreatic islets, and enlargement of fat tissues in obesity mice. The phosphorylation of IRS-1 and AKT was increased significantly in muscle tissues and AMPK phosphorylation and the GLUT4 and Sirt1 expression were decreased significantly in muscle tissues after the AFB administration. Conclusions: Our study indicates that AFB extract improves symptoms of obesity through regulation of energy regulating proteins in muscle tissues.

The purpose of this study was to assess the quality characteristics of Moju made with Hovenia dulcis Thunb. and its physiological effects on ICR mice. According to the sensory score, we selected Moju made with 1% Hovenia dulcis Thunb. among Moju made with 0, 0.5, 1, 5, and 10% Hovenia dulcis Thunb. Compared to Moju made without Hovenia dulcis Thunb., Moju made with 1% Hovenia dulcis Thunb. had higher proportions of moisture (86.77 g/100 g) and carbohydrates (11.86 g/100 g). The mean values of the physicochemical analyses were as follows: pH 4.91, acidity 0.28, $^{\circ}Brix$ 12.63, reducing sugar 68.97, alcohol content 0.1, alcohol density 0.998. Moju made with 1% Hovenia dulcis Thunb. did not have effects on DPPH radical scavenging activity; however, superoxide dismutase activity was significantly higher than that of Moju made without Hovenia dulcis Thunb. For assessing physiological activities, 4-week-old male ICR mice were divided into six groups (n=10): normal control group (NC), ethanol-administered group (EC), EC plus low-dose Moju made with 0% Hovenia dulcis Thunb. (MCL), EC plus high-dose Moju made with 0% Hovenia dulcis Thunb. (MCH), EC plus low-dose Moju made with 1% Hovenia dulcis Thunb. (MDL), and EC plus high-dose Moju made with 1% Hovenia dulcis Thunb. (MDH). Serum triglyceride (TG) level was reduced by 11.17% and 19.61% in the MDL and MDH groups, respectively, compared to the EC group. Serum total-cholesterol levels of MDL and MDH groups were significantly lower as compared to the EC group. Serum high-density lipoprotein-cholesterol levels of the MDL and MDH groups were significantly higher than those of the EC group. Liver TG levels were significantly reduced in the MCL and MDL groups. From these results, Moju made with Hovenia dulcis Thunb. demonstrated antioxidant activity and reduction of hyperlipidemia markers. Therefore, Moju made with Hovenia dulcis Thunb. can serve as a non-alcoholic beverage and functional food source.

LPS induces the synthesis of several inflammatory cytokine, chemokine, NO and inflammation in the liver of rats. The purpose of this study was to investigate the preventive effects of Rubus coreanum Miquel (RCM) In lipid metabolism. RCM of 100 mg/kg concentration was intraperitoneally administered into rats at dose of 1.5ml/kg for 20 days. On the day 21, 1.5ml/kg of LPS was injected 4 hours before anesthetization. We examined the lipid-related functions by measuring the levels of triglyceride (TG), total cholesterol (TC), total lipid (TL), high-density lipoprotein cholesterol (HDL-C) in serum and malondialdehyde(MDA) in liver tissue. The results showed that LPS treatment increased the values of TG, TC, TL and MDA, decreasing that of HDL-C. But RCM pretreatment decreased the high values of TG, TC, TL and MDA to the low values and increased the low value of HDL-C to the high value. These results suggested that RCM could be used as the potential candidate for the lipid metabolism natural supplement.

Maqui berry are known as one of the "superfoods" and can purportedly improve health. The effects of orally administered maqui berry extract on biological parameters such as serum lipids and blood cells in healthy subjects were investigated in rats in vivo for 2 weeks. Possible causes of harmful effects on liver and kidney function were also examined. After oral administration of maqui berry extract, levels of serum triglyceride (TG) were decreased to almost 30% less from the control, and high density lipoprotein cholesterol (HDL-C) was increased to 18% more; thus, serum lipids profile seemed to be improved. The administration of maqui berry extract increased red blood cell concentration by 10% from the control, while both the hemoglobin and the mean corpuscular volume (MCV) were increased by 12%. Maqui berry extract also increased the concentration of serum total proteins by 30% of the control and that suggests protein metabolism might be improved. Moreover, maqui berry decreased serum levels of glutamin oxaloacetate transaminase (GOT) and glutamin pyruvate transaminase (GPT) by 12% from the control group so maqui berry improved liver function. This study suggests that oral administration of maqui berry extract may be helpful to improve those heath parameters like serum lipids profile, red blood cell level, liver protection. It would also be very useful for the development of high value products such as functional foods and pharmaceutics in the future.

This study was conducted to examine relationships between drinking patterns and metabolic syndrome among Korean adolescents. Statistically weighted data from the Sixth(2013-2015) Korea National Health and Nutrition Examination Survey data were analyzed. Multivariate logistic regression was used to determine relationships between adolescent drinking patterns and metabolic syndrome risk factors with adjustments for individual covariates. A total of 1,698 Korean adolescents (Men=901, Women=797) were identified. Among male adolescents, drinking frequency in the past year was significantly associated with triglyceride level (p for trend=0.03); and men who usually consumed ${\geq}5$ drinks on a typical occasion had a greater risk of high-triglyceride level (adjusted odds ratios: 2.72, 95% confidence intervals: 1.00-7.34, p=0.05). Among female adolescents, drinking frequency in the past year was significantly associated with blood high-density lipoprotein cholesterol level(p for trend=0.01). Drinking frequency and amount were associated with higher triglyceride level among male adolescents, indicating that adolescent drinking may be associated with increased metabolic syndrome development in adulthood. The study results suggest that continuous drinking prevention education and further research for adolescents and metabolic syndrome predictors are needed to prevent development of metabolic syndrome in adulthood.
Objectives : The purpose of this study was to examine the relationship between serum ferritin and the metabolic syndrome (MS). Methods : We conducted a cross-sectional study of 1,444 adults over age 40 and under age 70 that lived in a rural area and participated in a survey conducted as part of the Korean Rural Genomic Cohort Study (KRGCS). The MS was defined as the presence of at least three of the followings : elevated blood pressure, low high density lipoprotein cholesterol, elevated serum triglycerides, elevated plasma glucose, or abdominal obesity. After adjustment for age, alcohol intake, menopausal status, body mass index (BMI), high sensitivity C-reactive protein (hs-CRP), and alanine aminotransferase (ALT), odds ratios (ORs) for the prevalence of the MS by sex were calculated for quartiles of serum ferritin using logistic regression analysis. Results : The MS was more common in those persons , with the highest levels of serum ferritin, compared to persons with the lowest levels, in men (37.1% vs. 22.4%, p=0.006) and women (58.8% vs. 34.8, p<0.001). In both sexes, the greater the number of MS components presents, the greater the serum ferritin levels. After adjustment for age, alcohol intake, and menopausal status, the OR for metabolic syndrome, comparing the fourth quartile of ferritin with the first quartile, was 2.21 (95% confidence interval; CI=1.26-3.87; p-trend=0.024) in men and 2.10 (95% CI=1.40-3.17; p-trend=0.001) in women. However, after further adjustment for BMI, hs-CRP, and ALT, the ORs were statistically attenuated in both sexes. Conclusions : Moderately elevated serum ferritin levels were not independently associated with the prevalence of the MS after adjusting for other risk factors. Further studies are needed to obtain evidence concerning the association between serum ferritin levels and the MS.

Objectives : This study was conducted to investigate the associations of non alcoholic fatty liver with metabolic syndrome and the serum carotenoids. Methods : This study was conducted in a general hospital in South Korea from November, 2004 to August, 2005. The study subjects were 350 sampled persons who were aged from 40 years and older (males : 180, females : 170). They were grouped into the normal, mild and severe groups according to fat accumulation in their livers, as determined by ultrasonography. We analyzed the association between non alcoholic fatty liver and metabolic syndrome by multiple logistic regression analysis and we analyzed the association between non alcoholic fatty liver and the serum carotenoids by a general linear model(ANCOVA). Results : After adjustment for the effect of potential covariates, the prevalence of metabolic syndrome was associated with fat accumulation in the liver (p trend <0.001). If the odds ratio of normal group is 1.00, then that of the mild group is 2.80 (95% C.I=1.17-6.71) and that of the severe group is 7.29 (95% C.I=2.76-19.30). The prevalence of metabolic alterations fitting the criteria of metabolic syndrome, according to the class of fat accumulation in the liver, was significantly increased, except for criteria of high blood pressure, a large waist circumference and low HDL (high density lipoprotein) cholesterol level (p trend <0.001). The level of serum ${\beta}$-carotene was decreased according to the class of fat accumulation in the liver (p trend=0.036), but the levels of serum ${\alpha}$-carotene, lycopene, ${\beta}$-cryptoxanthin and lutein were not decreased. Conclusions : This study shows that non alcoholic fatty liver was associated with metabolic syndrome and with the serum ${\beta}$-carotene level.

An experiment was conducted to investigate the effect of feeding transgenic cottonseed (Bt.) vis-a-vis non-transgenic (non-Bt.) cottonseed on blood biochemical constituents in lactating Murrah buffaloes. Twenty Murrah buffaloes in mid-lactation were divided into 2 groups of 10 each. Animals of group I were fed with 39.5% non-transgenic cottonseed in concentrate mixture while the same percentage of transgenic (Bt.) cottonseed was included in the concentrate mixture fed to the animals of group II. Animals of both groups were fed with concentrate mixture to support their milk production requirements. Each buffalo was also offered 20 kg mixed green fodder (oats and berseem) and wheat straw ad libitum. The experimental feeding trial lasted for 35 days. There was no significant difference in the dry matter intake between the two groups of buffaloes. All the buffaloes gained body weight, however, the differences were non significant. Total erythrocyte count, hemoglobin content and packed cell volume were $9.27{\pm}0.70${\times}10^6/{\mu}l$, $13.01{\pm}0.60gdl$ and $34.87{\pm}1.47%$, respectively in group I with the corresponding figures of $8.88{\pm}0.33$, $12.99{\pm}0.52$ and $31.08{\pm}1.52$ in group II. The values of total erythrocyte count, haemoglobin content and packed cell volume did not differ significantly between the two groups of buffaloes. The concentration of plasma glucose, serum total proteins, albumin, globulin, triglycerides and high density lipoprotein were non significantly higher in buffaloes fed non-transgenic cottonseed than in buffaloes fed transgenic cottonseed. The cholesterol concentration was significantly (p<0.01) higher in buffaloes of group I ($136.84{\pm}8.40mg/dl$) than in buffaloes of group II ($105.20{\pm}1.85mg/dl$). The serum alkaline phosphotase, glutamic-oxaloacetate transaminase and glutamic-pyruate transaminase activities did not differ significantly between two groups of buffaloes. However, serum glutamic-pyruate transaminase activity was considerably high in buffaloes fed nontransgenic cottonseed as compared to buffaloes fed transgenic cottonseed. Bt. proteins in serum samples of animals of group II were not detected after 35 days of feeding trial. It was concluded that transgenic cottonseed and non-transgenic cottonseed have similar nutritional value without any adverse effects on health status of buffaloes as assessed from haematobiochemical constituents.
Lovastatin is a lipid lowering agent for the treatment of hypercholesterolemia and belongs to a new class of pharmacologic compounds called the 3-hydroxy-3-methylglutaryl coenzyme A (HMG CoA) reductase inhibitors. By competitively inhibiting HMG CoA reductase, lovastatin disrupts the biosynthesis of cholesterol in hepatic and peripheral cells and increases the synthesis of high-density-lipoprotein HDL) receptors. Following oral administration, the lactone ring of lovastatin is hydrolysed to the active inhibitor of HMG CoA reductase, lovastatin acid. Lovastatin is known to have poor oral absorption and wide individual variation. In this study, bioequivalence test of two lovastatin formulations, the test drug ($Lovaload^{TM}$, Chong Kun Dang Pharmaceutical Co.) and the reference drug ($Mevacor^{TM}$, Chung Wae Pharmaceutical Co.) were conducted according to the guidelines of Korea Food and Drug Administration (KFDA). A total of 18 healthy male volunteers, $31.90\pm3.60$ years old and $72.17\;7.88$ kg of body weight in average, were evaluated in a randomized crossover manner with a 2-week washout period. Concentrations of lovastatin acid in plasma were measured upto 12 hours following a single oral administration of eight tablets (20 mg of lovastatin per tablet) by high-performance liquid chromatography with UV detection at 238 nm. The area under the concentration-vs-time curve from 0 to 12 hours $(AUC_{0-12h})$ was calculated by the trapezoidal summation method. The statistical analysis showed that there are no significant differences in $AUC_{0-12h),\;C_{max}\;and\;T_{max}$ between the two formulations ($6.72\%,\;1.52\%,\;and\;0.88\$, respectively). The least significant differences between the formulations at $\alpha$=0.05 were less than $20\%\;(11.65\%,\;19.73\%,\;and\;14.81\%\;for\;AUC_{0-12h},\;C_{max}\;and\;T_{max}$, respectively). The $90\%$ confidence intervals for these parameters were also within $\pm20\%\;(-1.50{\leq}{\delta}{\leq}15.00$, $-12.50{\leq}{\delta}{\leq}15.50,\;and\;-9.64{\leq}{\delta]{\leq}11.40{\leq}\;for\;\;AUC_{0-12h}$ ,$C_{max}\;and\;T_{max}$, respectively). In conclusion, the new generic product $Lovaload^{TM}$ was proven to be bioequivalent with the reference drug.
