Objectives : The purpose of this study was to estimate the prevalence of metabolic syndrome, as defined by the ATP III report, in some Korean adults and use the Asian-Pacific proposed waist circumference to investigate waist circumference in some Korean adults using ROC curves. Methods : Study subjects were seventy-five thousands and ninety one persons(47,979 men and 27,111 women) who were selected among the patients who visited hospital for health evaluation from January 2000 to December 2001. All subjects were measured by height, weight, waist and hip circumferences, blood pressure and blood chemistry(lipid profile). Results : The mean age was $41.6{\pm}8.5$ years in men, $41.1{\pm}10.4$ years in women(p<0.05). Body mass index was in the normal range in 35.3% of men, and 55.9% of women. In both men and women, blood pressure, blood sugar, total cholesterol and triglyceride were positively correlated with BMI. waist circumference, and Broca's index(p<0.01). However HDL. choloesterol was correlated negatively (p< 0.01). Using ROC curve, the calculated waist circumferences were 84 cm in men(sensitivity 61.4% and specificity 64.1%) and 74 cm in women(sensitivity 65.0% and specificity 73.2%). The age adjusted prevalences of the metabolic syndrome as defined by NCEP ATP III were different for men(6.4%) and women(14.6%). The prevalence increased from 1.2% among participants aged 20 through 29years to 15.0% among participants aged over 60years in men(p<0.05) and from 1.6% to 27.4% respectively, in women. The age adjusted prevalences, as defined by using the waist circumference that was recommended by WHO's regional office for the western Pacific, were 10.6% in men and 18.5% in women. The age adjusted prevalences, as defined by using the waist circumference that was calculated by the ROC curves, were 17.1% in men and 22.4% in women. And All prevalences were increased following increased BMI and Broca's index. Conculsions : The prevalence of metabolic syndrome in some Korean adults was lower than that in western adults. Nevertheless because waist circumference was differed among race and region, application of the same criteria was not proper. Morcover, a higher awareness was required in women, because the prevalence of metabolic syndrome was rapidly increased with increment of age.
Objective : In this study, the addition of dried pomegranate concentrate powder (PCP) was affected the anti-climacterium activity of red clover dry extracts (RC) in ovariectomized (OVX) rats. Materials and methods : After bilateral OVX surgery, RC 40 mg/kg, PCP 20 mg/kg and RC:PCP 2:1 mixture (g/g) 120, 60 and 30 mg/kg (of body weight) were orally administered, once a day for 84 days, and then the changes on the serum estradiol levels, abdominal fat pad and uterus weights were observed for estrogenic effects. In addition, liver weights, serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels were also evaluated for hepatoprotective effects, and serum total cholesterol (TC), low density lipoprotein (LDL), high density lipoprotein (HDL) and triglyceride (TG) levels were monitored for hypolipidemic effects. Results : As a result of OVX, the estrogen-deficient climacterium symptoms, increments of abdominal fat pad weights, serum AST, ALT, TC, LDL and TG levels with decrease of uterus and liver weights, serum estradiol levels, were demonstrated. However, these estrogen-deficient climacterium symptoms induced by bilateral OVX in rats were significantly inhibited by continuous oral treatment of RC 40 mg/kg, PCP 20 mg/kg and RC:PCP 2:1 mixture (g/g) 120, 60 and 30 mg/kg, respectively. Conclusion : The results suggested that RC:PCP 2:1 mixtures synergistically increased the anti-climacterium effects of RC in OVX rats. It, therefore, is expected that RC:PCP 2:1 mixture will be promising as a new potent protective agents for relieving the climacterium symptoms.
Objectives : The present study investigated the anti-obese and blood flow improvement activities of aqueous extracts of ginseng berry (GBe) on the mild diabetic obese mice as compared with metformin. Methods : After end of 56 days of continuous oral administrations of GBe 150, 100 and 50 mg/kg, or metformin 250 mg/kg, anti-obese and blood flow improvement effects - the changes of body weights, body and abdominal fat density by in live dual-energy x-ray absorptionmetry (DEXA), tail bleeding time, prothrombin time (PT), activated partial thromboplastin time (aPTT), serum total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL) and high density lipoprotein (HDL) levels, aorta and serum cyclic guanosine monophosphate (cGMP), nitric oxide (NO) and endothelin (ET)-1 levels, aorta phosphorylated PI3K (pPI3K), phosphorylated Akt (pAkt) and phosphorylated p38 MAPK (pp38 MAPK) levels were systemically analyzed. In addition, aorta vascular dilation and constriction related gene mRNA expressions - PI3K, Akt, eNOS, p38 MAPK and ET-1 were also analyzed by realtime RT-PCR. Results : The obesity and related blood flow impairment, induced by 84 days of continuous HFD supply, were significantly inhibited by 56 days of continuous oral treatment of GBe 150, 100 and 50mg/kg, dose-dependently, and they also dramatically normalized the changes of the aorta vascular dilation and constriction related gene mRNA expressions, also dose-dependently. Especially, GBe 150 mg/kg constantly showed favorable inhibitory activities against type II diabetes related obesity and vascular disorders through PI3K/Akt pathway and p38 MAPK mediated cGMP, NO and ET-1 expression modulatory activities, as comparable to those of metformin 250 mg/kg in HFD mice. Conclusion : By assessing the key parameters for anti-obese and blood flow improvement activities on the HFD-induced mild diabetic obese mice, the present work demonstrated that GBe 150, 100 and 50 mg/kg showed favorable anti-obese and blood flow improvement effects in HFD-induced type II diabetic mice, through PI3K/Akt pathway and p38 MAPK mediated cGMP, NO and ET-1 expression modulatory activities.
This study was conducted to assess blood components caused by metabolic syndrome increasing in postmenopausal elderly women. The blood samples of these subjects were analyzed to investigate the correlation of plasma taurine levels and plasma homocysteine levels, and serum lipid profiles. The subjects were 33 elderly women($72.8{\pm}4.4$ years). Their mean height, weight and BMI were $150.5{\pm}5.7\;cm$, $57.5{\pm}6.3\;kg$ and $25.4{\pm}2.5\;kg/m^2$. 16 women of this study subjects have been chronic diseases such as hypertension or diabetes. Their fasting blood glucose was $98.2{\pm}24.0\;mg/d{\ell}$, and their plasma total cholesterol (TC), HDL-C, LDL-C, triglyceride(TG) were $216.5{\pm}29.9$, $52.1{\pm}10.7$, $145.7{\pm}27.9$ and $141.2{\pm}59.6\;mg/d{\ell}$, respectively. Their blood lipid profiles were higher than the standard levels of metabolic syndrome, thus these levels of lipid profiles may play a role as risk factors on the elderly person. Plasma taurine level of the subjects was $278.5{\pm}48.1\;{\mu}mol/{\ell}$, and their plasma homocysteine level was $12.8{\pm}2.9\;{\mu}mol/{\ell}$. The concentration of plasma vitamin $B_{12}$ was significantly decreased by aging(p<0.05). The correlation of plasma homocysteine and plasma folate showed significantly negative(p<0.05). Thus, the decreased levels of plasma vitamin $B_{12}$ and folate by aging might affect on the plasma homocyteine concentration acting as a risk factor of cardiovascular diseases for elderly person. The correlation of plasma taurine and hemoglobin, and their platelet showed significantly positive(p<0.05). In conclusion, the diet on the elderly person is one of the important factors to prevent their health from chronic diseases. This study recommends that well balanced diets are needed for elderly person to keep their health and prevent from metabolic syndrome.
Objectives : The aim of this study was to assess the relationship between metabolic syndrome and erythrocyte deform ability in acute stroke patients. Methods : Among 88 of the recruited patients, 52 were diagnosed as metabolic syndrome. We assessed their general characteristics, risk factors. We compared the assessed variables between metabolic syndrome and control group. We analyzed the relationship between metabolic syndrome and erythrocyte deform ability. We analyzed relationship between cardiovascular risk factors and erythrocyte deformability. Results : The general characteristics waist and hip circumference, waist/hip ratio were higher in metabolic syndrome group. The metabolic syndrome group was also diagnosed with hypertension, DM, and hyperlipidemia more often than the control group. The blood test metabolic syndrome group showed higher triglycerides, total lipids, fasting blood sugar, and 2 hours postprandial plasma glucose level and lower HDL-cholesterol than the control group. There were more patients diagnosed with Dampness-Phlegm in the metabolic syndrome group. There were more patients showing lower erythrocyte deform ability in the metabolic syndrome group. The plasma homocysteine level was negatively correlated with erythrocyte deform ability. Conclusion : The results reconfirmed that the risk factors are more in metabolic syndrome group. The results indicated that metabolic syndrome lead to a lower erythrocyte deform ability in small vessel disease stroke patients. The Plasma homocysteine level was negatively correlated with erythrocyte deform ability.
선행연구(12,13)에 따르면 10주간 ID1216을 투여한 비만 마우스에서 체중과 체지방이 감소하였고 이는 SIRT1-$PGC1{\alpha}$의 발현을 조절하여 나타나는 것으로 확인하였다. 본 연구는 $SIRT1-PGC1{\alpha}-PPAR{\alpha}$의 하위 기전인 UCPs, ACO, aP2의 발현 조절에 ID1216이 영향을 미쳐 그 효과를 나타내는 것을 추가로 확인한 것에 의미가 있다. 또한 10주간 ID1216을 투여한 비만 마우스의 혈액 분석 결과에서도 혈중 중성지방, LDL, HDL total cholesterol등의 혈중 지방질 수치가 개선됨과 동시에 free fatty acid의 농도는 감소하였는데 이는 ID1216이 HSL과 같은 지방질분해효소의 활성을 조절하여 중성지방의 분해과정에 관여하기는 하나 에너지 대사와 지방산 산화 과정에도 복합적으로 관여하여 최종적으로 나타내는 비만 대사 조절 효과에 의한 것으로 판단된다. 따라서 ID1216은 $SIRT1-PGC1{\alpha}-PPAR{\alpha}$ pathway를 촉진시켜 세포와 조직 수준에서 열발생(thermogenesis)에 관여하는 유전자인 UCP1, UCP2, UCP3의 발현을 증가시켰고 ${\beta}$-oxidation에 관여하는 유전자인 ACO와 aP2의 발현도 증가시켰으며 또한 지방분해(lypolysis)에 관여하는 유전자인 ATGL과 HSL의 발현을 증가시키는 분자생물학적 기전을 나타내어 체지방 감소 효과를 나타내는 것으로 확인되었다.
A feeding trial was carried out to determine the effects of chromium methionine (Cr-Met) chelate and forage level over two years, $1^{st}$ fattening and $2^{nd}$ fattening period on growth parameters, carcass characteristics and blood metabolites of 46 Korean native (Hanwoo, Bos Taurus, $BW=183{\pm}44kg$) steers. Treatments were: 1) Steers in the low forage (LF) group were fed diets that consisted of 60% concentrate and 40% forage; 2) Steers in the high forage (HF) group were fed diets that consisted of 40% concentrate and 60% forage. Following the $1^{st}$ fattening period, steers ($BW=480{\pm}37.6kg$) were randomly assigned to four treatment groups: LF (40 F plus no Cr-Met supplementation in the $2^{nd}$ fattening period), LFCM (40LF plus added 400 ppb of Cr-Met during the $2^{nd}$ fattening period), HF (60 F plus no added Cr-Met during the $2^{nd}$ fattening period) and HFCM (60 F plus added 400 ppb of Cr-Met in the $2^{nd}$ fattening period). Dry matter intake of the treatment diets did not differ during the raising and $1^{th}$ fattening period (P > 0.05). The ADG in the raising period showed no difference between the 40 F and 60 F groups (P > 0.05). Carcass characteristics including rib-eye area and meat yield index were higher in HF than the other treatment groups (P < 0.05). The HF group tended to show a higher (P = 0.08) marbling score than the LF group whereas the HFCM group showed a higher marbling score than the LFCM group (P < 0.05). HDL was higher and LDL lower in groups fed with Cr-Met than in other groups whereas glucose showed the lowest value in HF group (P < 0.05). Triglyceride (TG), Cholesterol, PUN and total protein (TP) were the same among all treatment groups (P > 0.05). The Insulin concentration in the blood was significantly higher for the HFCM group than for the LF, LFCM and HF groups (P < 0.05). It is concluded that supplementation of chromium-methionine chelate could improve meat quality in beef steers.
The increased oxidative stress may play an important role on the pathogenesis of diabetes and diabetic complications, and the blood level of vitamin C and lipid peroxidation in NIDDM patients may be used as an indicator for oxidative stress. However there is only scanty evidence on the blood level of vitamin C in NIDDM patients with or without diabetic complications. The study population consisted of 90 NIDDM patients(diabetes without complication, 48, and diabetes with complications, 42) and 41 normal subjects. The 42 diabetic complications were divided into 3 groups : 15 diabetic nephropathy, 18 diabetic neuropathy, 9 diabetic retinopathy. The anthropometric data and blood biochemical data were studied. The dietary intake was determined by 24 hour recall methods and food frequency questionnaire. The plasma concentrations of MDA and vitamin C were determined by fluorophotometer and HPLC respectively. 1) In blood lipoprotein study, diabetes with complication had higher level of TG than diabetes without complications, while no significant differences in total cholesterol, HDL, and LDL were shown. Diabetic neuropathy had the highest TG level among diabetic complication groups. 2) The intakes of vitamin B complexes(vitamin B$_2$, vitamin B$_{6}$, not vitamin B$_1$) and antioxidant vitamins(vitamin A and vitamin E, not vitamin C) and certain minerals such as iron and calcium in diabetes were not sufficient but the intakes of energy, protein, niacin, and phosphorus in diabetes were sufficient. The dietary intakes between diabetes with-and without complications were not significantly different. Among diabetic complications, the diabetic retinopathy had the lowest intake of vitamin B$_2$ and B$_{6}$(p < 0.05). the diabetic neuropathy or nephropathy consumed extremely low amount of vitamin A. 3) The MDA concentrations of NIDDM was significantly higher than that in controls(p < 0. 05) while no significant difference in the MDA concentration between with and without complications was shown. Although there were no statistical differences, the diabetic nephropathy and diabetic neuropathy showed the higher concentration of MDA than the diabetes without complications or diabetic retinopathy. 4) The plasma concentration of vitamin C in controls was higher than that in diabetes(p < 0.05) while the plasma vitamin C in diabetes with and without complications were similar. In diabetic complications, no differences in plasma vitamin C concentration of three groups were shown. This study showed that the oxidative stress in NIDDM patients was highly increased and the vitamin C reserve was significantly depleted, as compared with normals, although their intakes of vitamin C met korean RDA, which means that diabetes need more vitamin C intake to decrease oxidative stress in NIDDM patients.nts.
BACKGROUND: Groundwater is believed to possess many beneficial effects due to its natural source of various minerals. In this study, we examined the effects of natural Jeju groundwater S1 (Samdasoo$^{TM}$), S2 and S3 pumped up from different locations of Jeju Island, Korea, along with local tap water, on body weight gain, serum lipids and lipoproteins, and liver histopathology in high-fat diet-induced hyperlipidemic rats. MATERIALS/METHODS: Rats were randomly and equally divided into 6 groups. Different water samples were supplied to the hyperlipidemic rats as their daily drinking water and the widely-used anti-hyperlipidemic drug simvastatin was used as a positive control. Body weight, serum lipids and lipoproteins were measured weekly. Liver weight, liver index and liver histopathology were examined after the execution of the rats. RESULTS: After drinking Jeju groundwaters for two months, S2 but not S3 significantly reduced weight growth and serum triglycerides levels and increased high density lipoprotein-C (HDL-C) without affecting total cholesterol or LDL-C. S1 and particularly S2 significantly reduced the severity of liver hypertrophy and steatosis. All Groundwaters had much higher contents of vanadium (S3>S2>S1>>tap water) whereas S1 and S2 but not S3 markedly blocked autoxidation of ferrous ions. CONCLUSION: Jeju Groundwater S1 and particularly S2 exhibit protective effects against hyperlipidemia and fatty liver and hypothesize that the beneficial effect of Jeju Groundwaters may be contributed from blockade of autoxidation of ferrous ions rather than their high contents of vanadium.
Dietary fatty acid including mainly palmitic acid and stearic acid was fed to fattening cattle and its effect on body weight gain, plasma lipid contents and rumen liquid fermentation in vitro was examined. In expt. 1, the effect of dietary fatty acid on body weight gain and plasma lipid concentrations was examined. In the control diet group, cattle were fed 1 kg/day of rice straw and concentrate which satisfied the requirement. In the fatty acid group, cattle were given 250 g/d of fatty acid with the same diet of the control diet group. In the excess concentrate group, cattle were given the same diet of the control diet group plus 735 g/d of concentrate corresponding to the same TDN of 250 g/d of fatty acid. Diets were given for 7 days. Body weight gain of cattle given dietary fatty acid was significantly greater than that of cattle fed only rice straw and concentrate. When dietary fatty acid was added to cattle feed, plasma NEFA and HDL-cholesterol concentrations increased. In expt. 2, the influence of dietary fatty acid on gas production and VFA profile in the rumen liquid was investigated in vitro. In the control group, 10 mg of rice straw and 90 mg of concentrate were incubated in the rumen fluid. In the excess concentrate group, 10 mg of rice straw and 97.5 mg of concentrate were incubated. In the fatty acid group, 10 mg of rice straw, 90 mg of concentrate and 2.5 mg of fatty acids were incubated. The rumen liquid mixed with feed materials was incubated for 24 h and the cumulative gas volume was measured. The VFA profile was also measured. Cumulative gas volume in the rumen liquid with fatty acid was equal to the control. Excess concentrate increased cumulative gas volume compared to the fatty acid group. There was no significant difference in total VFA concentration between experimental diet groups. It is suggested that dietary fatty acid has the potency to improve growth performance in fattening cattle without failure in rumen fermentation.
