Gallbladder polyps (GBPs) may be a cause of gallbladder cancer. The known risk factors for GBPs are male gender, obesity, metabolic syndrome, and dyslipidemia. Especially, male gender has been known that it strongly affects on the prevalence of GBPs. Therefore, this study aimed to investigate risk factors affecting the prevalence of GBPs among adults on Jeju Island according to genders. We examined 5,574 subjects who visited a single health-screening center in Jeju between January 2015 and December 2019. Univariate and multiple logistic regression analysis were performed to identify risk factors affecting the prevalence of GBPs. The prevalence of GBPs were 8.9% in male subjects and 8.1% in female subjects, respectively. Multivariate analysis revealed that ≥60 year age (odds ratio [OR] 0.659; P=0.027) and aspartate aminotransferase >32 IU/L (OR 0.658; P=0.009) in male subjects and high-density lipoprotein-cholesterol ≥60 mg/dL (OR 0.514; P=0.013) in female subjects were independent factors affecting the prevalence of GBPs. The prevalence of GBPs in men (8.9%) is comparable to that in women (8.1%) on Jeju Island. Age <60 years and the high level of aspartate aminotransferase in men and the greater level of high-density lipoprotein-cholesterol in women were independent risk factors of GBPs on Jeju Island.

BACKGROUND/OBJECTIVES: High levels of plasma low-density lipoprotein (LDL) cholesterol are an important determinant of atherosclerotic lesion formation. The disruption of cholesterol efflux or reverse cholesterol transport (RCT) in peripheral tissues and macrophages may promote atherogenesis. The aim of the current study was to examine whether bioactive ellagic acid, a functional food component, improved RCT functionality and high-density lipoprotein (HDL) function in diet-induced atherogenesis of apolipoproteins E (apoE) knockout (KO) mice. MATERIALS/METHODS: Wild type mice and apoE KO mice were fed a high-cholesterol Paigen diet for 10 weeks to induce hypercholesterolemia and atherosclerosis, and concomitantly received 10 mg/kg ellagic acid via gavage. RESULTS: Supplying ellagic acid enhanced induction of apoE and ATP-binding cassette (ABC) transporter G1 in oxidized LDL-exposed macrophages, facilitating cholesterol efflux associated with RCT. Oral administration of ellagic acid to apoE KO mice fed on Paigen diet improved hypercholesterolemia with reduced atherogenic index. This compound enhanced the expression of ABC transporters in peritoneal macrophages isolated from apoE KO mice fed on Paigen diet, indicating increased cholesterol efflux. Plasma levels of cholesterol ester transport protein and phospholipid transport protein involved in RCT were elevated in mice lack of apoE gene, which was substantially reduced by supplementing ellagic acid to Paigen diet-fed mice. In addition, ellagic acid attenuated hepatic lipid accumulation in apoE KO mice, evidenced by staining of hematoxylin and eosin and oil red O. Furthermore, the supplementation of 10 mg/kg ellagic acid favorably influenced the transcriptional levels of hepatic LDL receptor and scavenger receptor-B1 in Paigen diet-fed apoE KO mice. CONCLUSION: Ellagic acid may be an athero-protective dietary compound encumbering diet-induced atherogenesis though improving the RCT functionality.

Objectives: Epicardial fat is true visceral fat that is known to be associated with metabolic syndrome, high abdominal fat, insulin resistance, coronary artery diseases, low coronary flow reserve and subclinical atherosclerosis. Dampness-Phlegm pattern is one of the pattern diagnosis of traditional Korean medicine. Previous studies showed that Dampness-Phlegm pattern is associated with hypertension, dyslipidemia, metabolic syndrome. This study is intended to find association between Dampness-Phlegm pattern and epicardial fat thickness. Methods: This study was a community-based single center trial. Ischemic stroke patients within 30 days after their ictus were enrolled. Epicardial fat thickness was measured using transthoracic echocardiography. Other measured and obtained variables are medical history, weight, height, body mass index, fasting blood glucose, cholesterol, triglycerol, high density lipoprotein, lipid and low density lipoprotein. Results: Three hundred sixty six were enlisted, and one hundred forty were diagnosed with the Dampness-Phlegm pattern. Dampness-Phlegm pattern group had significantly thicker epicardial fat. Binary logistic regression also showed statistically significant result. Conclusions: This study showed close association between epicardial fat and Dampness-Phlegm pattern. This result suggests a clue to standardization of pattern identification.

We measured plasma concentrations of high density lipoprotein, total cholesterol and triglycerides in 31 patients with history of kawasaki disease during acute stage and convalescence stage. High density lipoprotein cholesterol and total cholesterol concentrations were significantly lower(P<0.001) in samples taken within 11 days of the onset of illness($28.7{\pm}12.4mg/dl$ and $145.20{\pm}29.60mg/dl$) than in the second samples taken 1-2months after onset of disease($51.5{\pm}15.2mg/dl$ and $175.4{\pm}29.0mg/dl$). Change of triglycerides was not significant. There was no correlation between the serum cholesterol cencentration and coronary aneurysm and continued long term surveillance of much population is necessary to monitor lipid level and their relation to development of premature coronary atherosclerosis.

This study was conducted to investigate the relationships among the levels of fasting serum insulin, free fatty acid, lipids and anthropometry in normal-weight female college students. Serum insulin and free fatty acid levels were negatively correlated. However, insulin, triglyceride, and cholesterol levels were not correlated with fat mass or BMI(body mass index). The ability of anthropometric and biochemical indicators to predict fatness could be important for epidemiologic and clinical research. In the subjects, waist cirumference was correlated with BMI, fat mass and percent body fat, and HDLC/CHOL (high density lipoprotein cholesterol/cholesterol)was correlated with body weight, BMI, and fat mass. Our data suggests than waist circumference and HDLC/CHOL are predictors of fatness, whereas WHR apears to be a less important contributor to fatness in female college students.

We recently reported that a water extract of laurel or turmeric, 1,8-cineole enriched fractions, showed hypolipidemic activity in the zebrafish model. Therefore, the present study investigated the cineole's anti-oxidant and anti-inflammatory activities in lipoprotein metabolism in vitro and in vivo. Cineole had inhibitory effects on cupric ion-mediated oxidation of lipoproteins in general, while simultaneously enhancing ferric ion removal ability in high-density lipoprotein (HDL). Hypercholesterolemia was induced in zebrafish using cholesterol-feeding treatment, 4% cholesterol, for 3 weeks. After feeding with or without the addition of cineole, the results revealed that cineole possessed lipid-lowering and anti-inflammatory activities in hypercholesterolemic zebrafish. In addition, serum amyloid A and interleukin-6 levels were lowered and lipid accumulation was decreased in the liver. Conclusively, 1,8-cineole was found to have anti-oxidant activities in lipoprotein metabolism both in vitro and in vivo with simultaneous reduction of lipid accumulation in the liver of zebrafish.

This study was conducted to clarify the relationship of body fat percent with serum lipid level and blood pressure in adults. The study subjects were 472 men and 189 women who visited Multiphasic Health Screening Center of Yeungnam University Hospital in Taegu from May 20 to September 30, 1994. The relationship of serum lipid and blood pressure with BMI, Katsura index, atherogenic index, which calculated from the health screening data and body fat percent measured by impedance fat meter(model SIF-819) were analyzed. Three groups were classified as Group I (men : body fat Percent $\geq$ 20, women : body fat percent $\geq$ 25), Group II (men : 15 $\leq$ body fat percent< 20, women : 20 $\leq$ body fat percent< 25), Group III(men : body fat percent < 15, women body fat percent <20). In this study, Group I accounted for 3.2% in men, 3.7% in women. Weight was significantly different among three groups in both sexes(p<0.01) and height was not significantly different among three groups. In men, serum total cholesterol, triglyceride, high density lipoprotein, low density lipoprotein, atherogenic index were significantly different(p<0.01). In women, serum total cholesterol and low density lipoprotein were significantly different(p<0.05) but there was no differences in triglyceride and high density lipoprotein among three groups. BMI and Katsura index were significantly different among three groups in both sexes(p<0.01). In men, body fat percent was positively correlated with weight, BMI, Katsura index, total cholesterol, triglyceride, low density lipoprotein, atherogenic index and systolic and diastolic blood pressures, and negatively correlated with high density lipoprotein. In women, body fat percent was positively correlated with age, height, weight, BMI, Katsura index, total cholesterol, triglyceride, low density lipoprotein and atherogenic index, and negatively correlated with high density lipoprotein. But there was no significant correlation between body fat percent and blood pressure in women. In multiple regression analysis for total cholesterol, fat percent, age and BMI were significant independent variables in men$(p<0.05,\;R^2=0.1286)$, and body fat percent and age in women$(p<0.05,\;R^2=0.3399)$. In case of LDL/HDL ratio, only BMI was a significant independent variable in menu$(p<0.01,\;R^2=0.0954)$, and body fat percent, age and BMI in women$(p<0.05,\;R^2=0.3164)$. In multiple regression analysis, age, low density lipoprotein and total cholesterol were significant independent variables on systolic blood pressure in men$(p<0.05,\;R^2=0.1297)$, age and total cholesterol in women$(p<0.05,\;R^2=0.1705)$. On diastolic blood pressure, only age was a significantly independent variable in men$(p<0.01,\;R^2=0.0972)$ and women$(p<0.01,\;R^2=0.1218)$. From the result of this study, it could concluded that body fat percent was significantly associated with other obesity indices and serum lipid, but had no significant association with blood pressure. To establish the relationship of body fat percent with blood pressure, further study which consider other variables that may have an effect on blood pressure should be performed.

The definite mechanism in the control of triglyceride metabolism is not well understood. Nowadays, it has been known that the polymorphism of apolipoprotein C-III $Sst$ I was an important candidate for contributing to the control of triglyceride metabolism. In 298 Korean women aged 30 years or more, the genotypes of apolipoprotein C-III $Sst$ I were statistically compared with total blood cholesterol, triglyceride, high density lipoprotein, fasting blood sugar and hemoglobin A1c. Multiple logistic regression analysis was carried out to compare the odd-ratios of hypertriglyceridemia, hypercholesterolemia and diabetes mellitus with them. The differences among the polymorphic types ($S_1S_1$, $S_1S_2$, and $S_2S_2$) were not statistically significant in the distribution of triglyceride, total cholesterol, high density lipoprotein, fasting blood sugar, and hemoglobin A1c. There were not statistically significant in the odds ratios of the hypertriglyceridemia, hypercholesterolemia, and diabetes mellitus, neither. Those were not statistically significant. This study did not show that there was any association between the polymorphism of apolipoprotein C-III $Sst$ I and various laboratory values-total blood cholesterol, triglyceride, high density lipoprotein, fasting blood sugar and hemoglobin A1c.

Objective : This study was conducted to investigate anti-obesity effects of mixed-Powder(Raphani Semen, Coicis Semen, Poria, Plantaginis Testa & Theae folium)(HP) & mixed water extract(Citri Pericarpium, Crataegi Fructus, Maydis Stigma, Allium Skin) (HE) in mice fed a high-fat diet. Method : 50 Female ICR mice were divided into six groups; Normal group (Ve), high-fat diet group (Po), Po+HP(0.6g/kg) group(HP), Po+HE(1g/kg) group(HE), Po+(HP+HE) group(HPE), Po+(HP+HE)*2 group(DHPE). For 8 weeks, these groups were fed their respective diets. Body weight, liver weight and weights of adipose tissues, GOT/GPT index changes & Blood Glucose index changes were measured respectively. Lipid profiles in serum were analyzed by kit of blood. Results : Groups HP, HE, HPE, DHPE had significantly reduced body weight, liver weight, adipose tissue weights and GOT/GPT index, blood glucose index compared to the Po group. Also, serum triglyceride and total cholesterol, low density lipoprotein, were significantly reduced when compared to the Po group. Group G1 had significantly increased high density lipoprotein levels. Conclusion : Mixed powder (HP) & mixed water extract (HE) show anti-obesity effects in mice fed a high-fat diet.

Epidemiological studies have indicated that a relationship between overweight and cardiovascular disease exists. To assess the relationship of unfavorable changes in serum lipid concentrations, apolipoprotein B, lipoprotein(a), blood sugar and blood pressure to anthropometric variables, nutrient intakes and dietary behavior,64 obese children were chosen as subjects and 24-hour dietary intake, dietary behavior as well as blood pressure, apolipoprotein B, lipoprotein(a), three kinds of cholesterol concentrations were measured in November 1976. More than half(57.8%) of the children had serum cholesterol concentrations over 175mg/d1, and 26.6% of them had over 200mg/d1 and this group could be classified as a high risk group. Abdominal obesity as measured with waist circumference and waist hip ratio was negatively co..elated to high density lipop개tein(HDL) cholesterol. Dietary behavior rather than nutrient intakes appeared to have associations with unfavorable lipid profiles. Total dietary behavior scores and fish and bean product consumption had strong correlations with potentially atherogenic lipoprotein concentrations. This study suggests that fir the early prevention of cardiovascular disease, waist hip ratio together with obese rate should be included in selective programs to identify risk group of children in Korea. furthermore, interventions in cardiovascular disease risk groups in obese children should emphasize maintenance of ideal body weight through reducing body fat and adopting desirable dietary behaviors such as increasing intake of fish or bean products.
