Dietary and other factors affecting serum lipid levels of 103 rural women aged 30-76 years were assessed. Data for dietary intakes were obtained by 24-hour recall method. Body weight, height and blood pressure were measured and BMI was calculated from the anthropometric data. Serum samples were collected and analyzed for TG and lipoprotein fractions. Relation of the factors with serum lipid concentration was analyzed by Pearson's correlation coefficient(r). The results were summarized as follows: The weight, hight and BMI of the subjects were 56.8kg, 152.4cm and 24.5k/==, respectively. 31.8% of the subjects under 50 years of age($\leq$49yr group) and 61.0% of the subjects from 50 years up(==50yr group) were classified as hyperlipidemia. Most of the subjects had normal blood pressure but 8.5% were hypertensive. Total food intake of hyperlipidemic subjects was more than those of normal subjects in both age groups. Nutrients intake also tended to be higher in hyperlipidemic subjects of $\geq$50yr group. Intake of some foods like nuts, milk, or meat affected serum lipid profile even though the effects was somewhat different between two age groups. Body weight was positively related with serum TG and VLDL-cholesterol in $\leq$49yr group, and body weight as well as height and BMI affected serum lipid level in $\geq$50yr group. In summarization, it appeared that hyperlipidemia was a serious health problem in rural women. Hypertriglyceridemia due to sharp increase after 50 years old was remarkable and further research should be performed to determine the related factors in the near future.

The purpose of this study was to investigate the effects of medical nutrition therapy(MNT) on plasma lipid levels of hyperlipidemic patients with apo E3 genotype according to Sasang Constitutions. From March to July, 2001, the 33 hyperlipidemic patients admitted to K University Medical Center were studied. The study subjects were classified according to their Sasang constitutions by QSCC II questionnaire which have been used at K University Oriental Medical Center. The anthropometric assessments, blood analysis, and apo E genetic typing were carried out. Nutrient intake was determined by food record method of food taken during two weekdays and one weekend. The MNT including the instruction for hypolipidemic and hypocholesterolemic diet (step l diet) was performed for 12 weeks. The results are as follow; (1) The mean age of hyperlipidemic patients was $49.91{\pm}8.48$ years. (2) The distributions of Sasang Constitution were 60.6% of Tae-eum, 21.2% of So-yang, and 18.2% of So-eum. The distributions of apo E genotype were 6.5% of apo E2/3, 78.8% of apo E 3/3, and 15.2% of apo E 3/4. (3) The nutrient consumption of the apo E3 subjects before the MNT showed lower calorie, iron, calcium, and vitamin B2 intakes than the RDAs for each nutrients with no significant differences among the constitutions. After 12-week of MNT, only the fat consumption was decreased in the Tae-eum group. The MNT did not change the pattern of food intake. (4) The plasma level of triglyceride, total cholesterol, and LDL-C were not changed after MNT in the three constitutional groups. The level of HDL-C was significantly increased significantly in Tae-eum and So-yang group and the level of homocystein was lowered in Tae-eum group after MNT. It could be concluded that the 12-weeks MNT with hypolipidemic and hypocholesterolemic diet did not change the level of total cholesterol, triglyceride, and LDL-C effectively regardless of Sasang constitutions even though the subjects' dietary intake was improved by MNT.

This study was investigated the mechanism of action of n-6/n-3 fatty acid ratio on the metabolic partitioning of blood glycerolipids by in vivo monitoring technique in hyperlipidemic animal model rats. The ratio of cholesteryl 14C-oleate metabolized in the liver of total glycerolipids was lower in the order of n-6/n-3 ratios of 4:1, 15:1, 30:1 and control group (p<0.05). The secretion amount of phospholipid was higher in the order of n-6/n-3 ratio 4:1, 15:1, 30:1 than the control (p<0.05). The secretion amount of triglyceride was lower in especially 4:1, in order of n-6/n-3 4:1, 15:1 and 30:1 compared with the control. The ratio of phospholipid partitioning to total glycerolipid was high in orfer of n-6/n-3 ratio 4:1, 15:1, 30:1 and control (p<0.05). The triacylglycerol partitioning (%) via liver was higher 72.97, 75.93, 78.12% in n-6/n-3 4;1, 15:1, 30:1, respectively than the control of 82.25%, according to increased n-6/n-3 (p<0.05). The phospholipid partitioning (%) was lower 25.15, 18.87, 18.15% in n-6/n-3 4;1, 15:1, 30:1, respectively, compared to control 11.04%, according to increased n-6/n-3 (p<0.05).

5'-AMP-activated protein kinase (AMPK) is a heterotrimeric complex consisting of a catalytic ($\alpha$) and two regulatory ($\beta$ and $\gamma$) subunits. Two isoforms are known for catalytic subunit (${\alpha}1$, ${\alpha}2$) and are encoded by different genes. To assess the metabolic effects of $AMPK{\alpha}1$, we examined the effects of overexpression of adenoviral-mediated $AMPK{\alpha}1$ in hyperlipidemic type 2 diabetic rats. The Otsuka Long-Evans Tokushima Fatty (OLETF) rat is an established animal model of type 2 diabetes that exhibits chronic and slowly progressive hyperglycemia and hyperlipidemia. Thirty five-week-old overt type 2 diabetic rats (n=10) were administered intravenously with Ad.$AMPK{\alpha}1$. AMPK activity was measured by phosphorylation of acetyl CoA carboxlyase (ACC). To investigate the changes of gene expression related glucose and lipid metabolism, quantitative real-time PCR was performed with liver tissues. Overexpression of $AMPK{\alpha}1$ showed that blood glucose concentration was decreased but that glucose tolerance was not completely recovered on 7th day after treatment. Plasma triglyceride concentration was decreased slightly, and hepatic triglyceride content was markedly reduced by decreasing expression of hepatic lipogenic genes. Overexpression of $AMPK{\alpha}1$ markedly improved hepatic steatosis and it may have effective role for improving hepatic lipid metabolism in hyperlipidemic state.

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.

Objective : The purpose of this report was to provide the information about activity and safety of Ojeok-san by analyzing domestic/international papers about Ojeok-san. Methods : Domestic/international papers related to Ojeok-san were reviewed and analyzed. These papers were then classified by year, experimental method and subject. Results : The following results were obtained in this study. 1. The studies of Ojeok-san started from 1984 and has continuously increased. The studies were mainly focused on experimental models rather than clinical studies. 2. By subject, papers related to safety were most common with 5 papers among 20 papers. Besides there were papers related to efficacy of analgesic, anti-hyperlipidemic, anti-blood stasis and treatment for uterine myoma. 3. The papers related to safety were mainly focused on the effect of Okeok-san on liver function, renal function or metal concentration of organs such as blood, brain, liver, kidney and bone. Ojeok-san proved to be safe, but more clinical studies regarding the safety are needed hereafter. 4. Papers related to analgesic, anti-pyretic, anti-phlogistic activities of Ojeok-san were in vivo studies, and other papers were about anti-hyperlipidemic activity, apoptosis inducing activity on uterine myeloma cell line and anti blood static activity on hydrocortisone acetate induced blood statis model. 5. Case reports were about anti-lipidemia, analgesic effect for mastalgia/back pain and anxiety disorder due to climacteric changes. Conclusion : Ojeok-san is being used in various ways with analgesic, anti-pyretic, anti-phlogistic, anti-hyperlipidemic, anti-tumor or anti-blood statis activity. However, mechanism study should be conducted at the molecular biology level and more clinical studies on the efficacy of Ojeok-san are needed.

Objective : The purpose of this study was to investigate the anti-obesity and anti-hyperlipidemic Effects of Taeyeumjowee-tang and its modified prescription on the animal model of obesity and hyperlipidemia induced high-fat diet. Method : 1) The extracts of Taeyeumjowee-tang (TJT) and its modified prescription, Taeyeumjoweetang gagam-bang (TJGB) were evaluated for its inhibitory effects on obesity. 2) The body weight and feed weight were determined in the pre-treated and post-treated mice and the lipid profiles in the serum were analyzed in order to evaluate the anti-hyperlipidemia action of the extracts. 3) The effect of each extract was investigated for the influences on monoamine oxidase activity and HMG-CoA reductase activity. Results 1. TJT and TJGB extracts dose-dependently reduced the body weight and feed intake in normal mice. The effect of TJGB extract was better than that of TJT extract. 2. TJGB extract diminished the body weight increase and reduced the feed intake in the pre-treatment or post-treatment of the extract 3. TJGB extract decreased the amount of total cholesterol slightly and triglyceride potently after the pre-treatment or post-treatment, but HDL cholesterol exhibited no remarkable change compared with control. 4. TJGB extract weakly potentiated the monoamine oxidase activity, but its effect was better than that of TJT extract. 5. TJGB extract weakly inhibited the HMG-CoA reductase activity, but its effect was better than that of TJT extract. Conclusion : Taeyeumjowee-tang and its modified prescription can clinically be useful as anti-obesity drug and also for the improvement of hyperlipidemia.

The present study examined the physiological effects of isoflavone-rich bean sprout on the lipid metabolism of hyperlipidemic rats. Experimental hyperlipidemia was induced by the AIN standard diet with 0.5% cholesterol,9.3% lard and 0.2% sodium cholate in SD rats. Experimental groups consisted of normal control, hyperlipidemic control, 1% or 5% bean sprout powder-supplemented groups, and 0.2% soybean isoflauone extract-supplemented group. Four weeks feeding of isoflavone-rich bean sprout powder or isoflavone extract resulted in a significant lowering of plasma cholesterol and lowering tendency of triglyceride levels. The levels of lipid peroxidation products in the kidney and heart tissues were also lowered by the supplementation of bean sprout powder or isoflavone extract. The activities of hepatic glutathione peroxidase and catalase were increased by the supplementation of bean sprout powder or soybean isoflavone extract. Plasma concentration of vitamin A was significantly raised in the group fed 0.5% bean sprout powder. The results of the study showed that the beneficial effects of isoflavone-rich bean sprout on lipid metabolism of hyperlipidemic animals were comparable with those of soybean isoflavone extract. The positive effect of bean sprout in improving lipid metabolism might be due to the combined action of isoflavone and dietary fiber.

This study was conducted to investigate the effect of Hijikia fusiforme extracts on serum lipid and liver antioxidative enzyme activities in triton-induced hyperlipidemic rats. Sprague-Dawley male rats divided into 7 groups : We injected saline to a normal group (N), saline and tween 80 to control groups (CS, CT) and tot extracts to experimental groups (CSA, CTEtOH, CTE, CTH) for 7 days and then injected triton at the last day. Serum and liver free cholesterol contents were significantly lower in hexane-treated group (CTH) than control group (CT) whereas serum HDL-cholesterol content was higher in aqueous extract group (CSA) than control group (CS). Total cholesterol and phospholipid contents in serum and liver were lower in aqueous extract group (CSA) than control group (CS). Serum and liver triglyceride contents were significantly lower in ethanol (CTEtOH) and hexane treated group (CTH) than control group (CT). Thiobarbituric acid reactive substances of liver were lower in tot extract groups (CSA, CTEtOH, CTE, CTH) than control groups (CS, CT). Superoxide dismutase activities in liver were significantly lower in aqueous extracts group (CSA) and hexane treated group (CTH) than control groups (CS, CT). Liver catalase activity was the lowest in ethylacetate extract group. These results showed that some Hijikia fusiforme extracts have reduction effect of lipid and antioxidative effect in triton-induced hyperlipidemic rats.

The effects of dietary supplementation of pacific saury on anti-hyperlipidemic activities were investigated using an animal test study in which normal rats were fed four different parts of saury, such as the whole body, meat, internal organs, or a mixture of head, caudal fin, and bone. Serum total lipid and triglyceride levels were significantly (p<0.05) reduced in rats fed saury meat at a dose of 200 mg/kg of body weight compared to hyperlipidemic control rats. There were also significant decreases in serum total cholesterol and LDL-cholesterol levels in the rats fed saury meat at 200 mg/kg of body weight. In addition, the atheroscrelosis index and superoxide dismutase in blood lipids were significantly (p<0.05) lowered in rats fed saury meat at 200 mg/kg of body weight compared to the control rats. In conclusion, our results indicate that saury meat contains unknown physiologically active components as than compared to other parts of saury, and has potential for use in the prevention of hyperlipidemic arteriosclerosis.
