Nutrition related factors were investigated in one hundred and two hypertensive patients(Male : 44, female : 58) before they started drug treatment or diet therapy. The mean age of men and women were 49.9 and 53.5, respectively. Among the men, their mean SBP and DBP were 165.8 mmHg/108.4 mmHg. Fifty six point eight percent of men was classified as having in stage 3 hypertension(SBP $\geq$ 180 mmHg, or DBP $\geq$ 110 mmHg) and 45.5% was classified as having low renin hypertension (serum renin < 2.5 ng/ml/h). The proportion of overweight or obesity assessed by BMI($\geq$ 25) or body fat percent( $\geq$ 21%) was 47.7% or 80.9%, respectively. Men showed 19.1% of hypertriglyceridemia(serum TG $\geq$ 200 mg/dl), 42.6% of hypercholesterolemia(serum cholesterol $\geq$ 220 mg/dl), and 17.0% was observed as having serum cholesterol higher than 240 mg/dl. The proportion of men with high risk of cardiovascular disease was 72.3% assessed by atherogenic index( $\geq$3.4). The prevalence of drinking was 86.4% including a daily drinking proportion of 15.8%. Among women, their mean SBP and DBP were 162.6 mmHg/104.3 mmHg. Less women(43.1%) were classified as having stage 3 hypertension and more women were observed in low renin hypertension(55.1%). The prevalence of obesity or overweight assessed by BMI( $\geq$ 25) was 31.0% and 76.3% with body At percent($\geq$28%). Women revealed 24.1% of hypertriglyceridemia and 36.2% of hypercholesterolemia. The proportion of women who showed high risk of cardiovascular disease(atherogenic index $\geq$ 3.4) was 63.8%. The smoking rate was 8.6% and drinking rate was 43.1%.

Hypolipidemic effect of Insamsansa-eum (ISE, Ren-Shen-Shan-Zah-Yin in Chinese) consisted of Red ginseng (RG; the steamed root of Panax ginseng C.A. Meyer) and Crataegii fructus (CF, the fruit of Crataegus pinnatifida BGE) is used frequently in China and Korea as a herbal medicine to treat arteriosclerosis, was investigated. Treatment of ISE significantly reduced blood triglyceride (TG) and total cholesterol (TC) levels in Triton WR-1339-induced hyperlipidemic mice and serum TG levels in corn oil-induced hypertriglyceridemic mice. ISE significantly lowered the high blood TG and TC levels as well as body and epididymal mass weights in hyperlipidemic mice induced by long-term feeding of a high-fat diet and increased blood HDL cholesterol level. ISE and its ingredients, RG and CF, inhibited pancreatic lipase and HMG-CoA reductase activities. Of its ingredients, RG reduced the blood TC level and HMG-CoA reductase activity more than CF. CF reduced blood TG level and pancreatic lipase activity more than RG. These finding suggest that the antihyperlipidemic effect of ISE may be due to synergistic inhibition of HMG-CoA reductase and pancreatic lipase by RG and CF, and that ISE may be effective hypolipidemic agents.

This study presents a meta-analysis research to test the improve effects of obesity and blood lipids on Salicronia herbacea L. (S. herbacea) intake in rats. Individual research materials were selected from database such as PubMed, Embase, RISS, DBpia, and NDSL. The Review Manager 5.3 version was used to estimate effect size through meta-analysis. A total of 9 studies were finally included. Body weight gains were decreased in S. herbacea-treated groups as compared to the high fat diet groups. But, no significant effect was observed on FER, liver index, and total cholesterol. In addition, the effect size of triglyceride was reduced, whereas high density lipoprotein (HDL)-cholesterol was increased in S. herbacea-treated group. In this meta-analysis, the results indicated that S. herbacea have a strong effect on anti-obesity through the blood lipids improvement.

This study was designed to evaluate the effect of a rice-based diet on body weight and serum lipid levels. Thirty male C57BL/6 mice were randomly divided into three groups and fed a high-fat diet (HFD), rice-based diet (RD), or bread-based diet (BD) for five weeks. Our results showed that the RD group had a significantly lower final body weight, although there was no significant difference in daily food intake among the groups. There was a reduction in body weight gains, adipose tissues weight, and adipocyte size of epididymal adipose tissue in the RD group (p<0.05). Also, serum triglycerides and total cholesterol in the RD group were significantly decreased compared to the BD group. RD also reduced fasting glucose and insulin levels. These results indicate that the intake of RD attenuates increases in body weight and serum lipid concentrations in mice, suggesting its benefits for the dietary control of obesity and hyperlipidemia.

This study was performed to investigate the effect of feeding garcinia cambogia extract (HCA) and/or L-carnitine and exercise (swimming) on body weight in rats. Forty-eight male rats (Charles River CD (SD) IGS) of eight weeks old and weighing $323.5\pm2.4g$ were raised for two months with high fat diet ($40\%$ fat as calorie) to induce obesity. After induction of obesity, rats weighing $552.8\pm5.8g$ were blocked into eight groups according to body weight and raised for six weeks with diet containing HCA and/or L-carnitine. Plasma aspartate aminotransferase, alanine aminotransferase, total protein and albumin levels were in normal ranges. Food and calorie intakes of H + C and H + C/H groups were highest among non-exercise (m) groups and exercise (I) groups. Food and calorie intakes of m groups were higher than those of I groups. E groups showed significantly lower body weight gain and calorie efficiency ratio than m groups and H/E group was the lowest among all groups. Perirenal fat pad weights of E groups were lower than m groups, and epididymal fat pad weights of H and H + C groups were lower than CO and C groups among m groups regardless of exercise treatment. Brown adipose tissue weights of I groups were higher than fn groups and highest in H/E group among all groups. Liver citrate lyase activities of H and C groups were lower than CO and H + C groups regardless of exercise treatment. The differences between NE groups and E groups were not found to be significantly. Liver carnitine acyltranferase activity was not significantly different among all groups. Fecal total lipid, triglyceride and total cholesterol excretions were found to be higher in H and H + C uoups compared to CO and C groups both in NE and E animals, those of lipid excretions of NE groups were higher than E groups. In conclusion, HCA was more effective in reduction of body weight and body fat than L-carnitine or HCA + L-carnitine. HCA ingestion with exercise was far more effective than without exercise treatment in reducing body weight and body fat.

Objectives : This study was designed to investigate effects of the combination with Korean Red Ginseng (Panax ginseng C.A. Meyer), Gastrodia Rhizoma (Gastrodia elata Blume) and Polygoni Multiflori Radix (Polygonum multiflorum Thunberg) on metabolic disorders including cholesterol and erectile dysfunction in hyperlipidemia rats.Methods : Animals were divided into six groups; Control with normal diet, high fat/cholesterol-diet (HFCD), fluvastatin, Korean Red Ginseng treated (KRG), and the combination treated (Korean Red Ginseng, Gastrodia Rhizoma and Polygoni Multiflori Radix; 1:1:1 for KGP1 and 2:1:1 for KGP2). The experimental groups initially received HFCD for 10 weeks and then treated orally with fluvastatin, KRG, KGP1 and KGP2 during the final 6 weeks. Erectile function was determined by the measurements of intracavernosal pressure (ICP) and maximal arterial pressure (MAP) after electrical stimulation of the cavernosal nerve.Results : KGP2 decreased the level of total cholesterol and LDL cholesterol in the sera of HFCD rats without no changes of body weights. KRG, KGP1 and KGP2 decreased the level of C-reactive protein (CRP) levels except of fluvastatin, synthetic HMG-CoA reductase inhibitor. KRG, KGP1 and KGP2 significantly increased the ICP, ICP/MAP ratio, area under the curve (AUC) compared with those of normal rat. Morphometric analyses showed that KRG, KGP1 and KGP2 increased the volume of smooth muscle and the regular arrangement of collagen fibers in corpus cavernosum of HFCD rats. The penile expression of eNOS was increased by KRG, KGP1 and KGP2.Conclusions : Based on these results, we suggest that the combination with Korean Red Ginseng, Gastrodia Rhizoma and Polygoni Multiflori may improve hyperlipidemia through regulating the lipid profiles and erectile dysfunction in rats.

Purpose: Obesity is often associated with disturbances in the mineral metabolism. The purpose of this study was to investigate the effects of high-fat diet-induced obesity on tissue zinc concentrations and zinc transporter expressions in mice. Methods: C57BL/6J male mice were fed either a control diet (10% energy from fat, control group) or a high-fat diet (45% energy from fat, obese group) for 15 weeks. The zinc concentrations in the serum, stool, and various tissues were measured by inductively coupled plasma (ICP)-atomic emission spectrophotometry or ICP-mass spectrophotometry. The levels of zinc transporter mRNAs in the liver, duodenum, and pancreas were measured by real-time RT-PCR. The levels of serum adipokines, such as leptin and IL-6, were determined. Results: The total body weight, adipose tissue weight, and hepatic TG and cholesterol concentrations were significantly higher in the obese group, as compared to the control group. The obese group had significantly higher levels of serum leptin and pro-inflammatory IL-6 concentrations, and had significantly lower levels of serum alkaline phosphatase activity. The zinc concentrations of the liver, kidney, duodenum, and pancreas were all significantly lower in the obese group than in the control group. On the other hand, the fecal zinc concentrations were significantly higher in the obese group than in the control group. The serum zinc concentrations were not significantly different between the two groups. The ZnT1 mRNA levels of the liver and the pancreas were significantly higher in the obese group, as compared to the control group. Hepatic Zip10 mRNA was also increased in the obese group. Conclusion: Our study findings suggest that obesity increases fecal zinc excretion and lowers the tissue zinc concentrations, which may be associated with alterations in the zinc transporter expressions.

This study described the effect of levan (9-2,6-linked fructose polymer) feeding on serum lipids, adiposity and uncoupling protein (UCP) expression in growing rats. Levan was synthesized from sucrose using bacterial levansucrase. UCP is a mitochondrial protein that uncouples the respiratory chain from oxidative Phosphorylation and generates heat instead of ATP, thereby increase energy expenditure. We observed that 3% or 5% levan containing diet reduced serum triglyceride levels, visceral and peritoneal fat mass and induced the UCP expression in rats fed high fat diet in previous study. To determine whether the intake of low level of levan may have the hypolipidemic and anti-obesity effect, 4 wk old Sprague Dawley male rats were fed AIN-76A diet for 6 wk, and sub-sequently fed 1% or 2% levan solution for further 5 wk. Intake of 1% levan in liquid form reduced serum triglyceride and serum total cholesterol levels to 50% and 66% of control group, respectively. Although epididymal and peritoneal fat masses were not affected by levan feeding, visceral fat mass was lower in 1% levan group compared to control group. The expression of UCP2 mRNA in brown adipose tissue, skeletal muscle and hypothalamus and UCP3 mRNA in skeletal muscle were not changed by levan feeding, while the UCP2 mRNA in white adipose tissue was up-regulated by levan feeding. In conclusions, intake of low level of levan solution reduced serum triglyceride and total cholesterol, restrained the visceral fat accumulation and increased UCP expression in white adipose tissue in rats. This study suggests that hypolipidemic and anti-obesity effect of levan attributed to anti-lipogenesis and inefficeint energy utilization by up-regulation of UCPs.

The purpose of this study is to discover a food material having anti-obesity effects and to disseminate information on the effects of the material to people who are interested in anti-obesity. For this study, 11 kinds of Auricularia (wood ear) spp., including 8 strains of Auricularia auricula-polytricha, and 3 strains of A. auricula-judae, were presented by the Jeollanamdo Agricultural Research & Extension Services. 3T3-L1 (preadipocyte cell) was used for identifying the inhibition effect on adipocyte differentiation. As a result, this study found that all the extracts had slightly different degrees of inhibition effects on adipocyte differentiation. Among the A. auricula-polytricha strains, strain 21001 showed the most significant effect (4.58%), and the inhibition effect of strain 21002 (4.43%) was the greatest among A. auricula-judae strains. Overall, the inhibition effect of A. auricula-polytricha strains was greater than that of A. auricula-judae strains. The results of mRNA and protein analysis also demonstrated that the inhibition effect of A. auricula-polytricha 21001 was superior to that of any other strains. An in vivo study using 56 ICR mice (6w, male), was performed for 4 weeks. A. auricula-polytricha 21001, which exhibited the most significant effect in the in vitro study was used to compose six different types of feeds. Daily body weight gain of the high-fat diet containing 0.2% 21001 extract feeding group was $0.22{\pm}0.08g$ (*p < 0.05), and it was 31.25% lower than that of the high-fat diet feeding group ($0.32{\pm}0.06$). Internal organ weight measurement and blood analysis were performed immediately after animal sacrifice. The results proved that treatment with more than 0.1% of A. auricula-polytricha strain 21001 could significantly reduce (more than *p < 0.05) the weight of liver and epididymal fat, and levels of glucose, total cholesterol, AST, and ALT in blood.

This study was designed to observe the effects of the feeding Gentiana scabra Bunge var.buergeri Max. extract on the improvement of the blood glucose, lipids in the serum of dietary hyperlipidemic rats (S.D. strain, ♂) fed the experimental diets for 4 weeks. Concentration of blood glucose was significantly higher in the cholesterol administration groups (group 2(cholesterol+water), 3(cholesterol+Gentiana scabra Bunge extract) than those in the control group(group 1 (water)). Blood glucose concentration was rather lower in the group 3(cholesterol+Gentiana scabra Bunge extract) than in the group 2(cholesterol+water). There was almost little significance among the groups. Concentration of total cholesterol in serum was significantly lower in the group 3 than those in the group 2. Concentration of LDL-cholesterol in serum was significantly lower in the group 3 than that in the group 2. In the ratio of HDL-cholesterol concentration to total cholesterol concentration, Gentiana scabra Bunge extract administration group was higher percentage than in the group 2. Concentration of free cholesterol and cholesteryl ester in serum was significantly lower in the group 3 than in the group 2. Concentrations of triglyceride and phospholipid in serum were decreased in the group 3 than in the high fat diet group. The activities of aspartate aminotransferase and alanine aminotransferase in serum were increased in the all experimental groups than in the control group. From the above research, the Gentiana scabra Bunge var.buergeri Max. exacts were effective on the improvement of the lipid composition in serum of dietary hyperlipidemic rats.
