계란급여에 따른 혈중지질특성과 콜레스테롤 대사에 관한 영향을 조사하기 위해 C57BL/6 마우스를 공시하여 일반식이군과 고콜레스테롤식이군으로 나눈 후 계란을 2%와 10% 첨가한 사료를 5주동안 급여하였다. 일반사양성적(체중, 사료섭취량, 사료효율), 혈액과 간조직, 분변의 지질함량 및 담즙산 농도를 측정하였다. 체중과 사료효율은 일반식이와 고콜레스테롤식이군 모두 유의적인 차이가 없었으나 사료섭취량은 10% 계란 첨가구에서 유의적인 증가를 보였다(p<0.05). HDL-C농도는 일반식이 급여군에서 2%와 10% 계란 첨가구 모두 유의적인 증가를 나타내었다(p<0.05). 간 조직 내 TG와 TC농도는 일반식이군에서 계란의 급여가 TG와 TC 증가에 영향을 미친 반면 고콜레스테롤식이군의 경우 TG는 유의적인 차이가 없었고, TC는 10% 계란 급여군에서 감소하였다(p<0.05). 분변의 콜레스테롤, 중성지질, 담즙산 농도는 일반식이군과 고콜레스테롤식이군 모두 계란의 첨가 수준이 증가할수록 TC와 TG함량이 유의적으로 증가하였다(p<0.05). 담즙산 농도 역시 일반식이 급여군에서 계란의 첨가수준이 증가할수록 대조군보다 높은 함량을 보여 계란이 분변의 콜레스테롤 함량에도 영향을 미친 것으로 판단된다.

This study was to examine the lipid metabolism of fermented Rhynchosia nulubilis (FRN) in obese rats. The abnormal content of blood lipids often results in metabolic diseases, such as obesity and hyperlipidemia. Seven weeks female Sprague-Dawley rats were divided into four groups and fed high fat diets for 44 days. Also FRN was administered orally for 44 days at 7.5 ml/kg of body weight of rats. The effects of the lipid metabolism were evaluated by total cholesterol (TC), triglyceride (TG), high density lipoprotein (HDL), low density lipoprotein (LDL), glutamic pyruvate transaminase (GPT) and glutamic oxalacetic transaminase (GOT) levels in sera. The levels of TC, TG, LDL and GPT in FRN-treated groups were lower than those in obese groups. While HDL levels were significantly increased. These results demonstrated that FRN had improving effects of lipid metabolism in the obese rats, suggesting that FRN would be used as an ingredient of the useful functional products.

Objectives: Dyslipidemia in diabetes mellitus is a significant risk factor for the development of cardiovascular complications. The aim of this study was to evaluate the effect of the ethyl-acetate fraction of an ethanolic extract from Streospermum suaveolens on lipid metabolism in streptozotocin (STZ)-induced diabetic rats. Methods: Diabetes was induced by intraperitonial injection of STZ (50 mg/kg). Diabetic rats were treated with an ethyl-acetate fraction orally at doses of 200 and 400 mg/kg daily for 14 days. On the $15^{th}$ day, serum lipid profiles, such as total cholesterol (TC), triglycerides (TG), low-density lipoprotein (LDL), and high-density lipoprotein (HDL), were estimated in experimental rats. The atherogenic (AI) and the coronary risk (CRI) indices were also evaluated. Results: The ethyl-acetate fraction at doses of 200 and 400 mg/kg significantly (P < 0.001) and dose-dependently reduced serum cholesterol, triglycerides and LDL, but increased HDL towards near normal levels as compared to diabetic control rats. The fraction also significantly (P < 0.001) lowered the atherogenic index (AI) and coronary risk index (CAI) in a dose-dependent manner. Conclusion: The present study demonstrated that the ethyl-acetate fraction of Stereospermum suaveolens exhibits a potent antihyperlipidemic activity in hyperglycemic rats and suggests that the plant may have therapeutic value in treating the diabetic complication of hyperlipidemia.

Purpose: The purpose of this study was to review the relationship between physical activity and cardiovascular outcomes in the Korean elderly. Methods: Experimental studies were located using PubMed, CINAHL, PsycINFO, Cochrane, RISS, KISS, and KoreaMed. The selected studies for analysis were 20 articles of cardiovascular outcomes (total cholesterol, triglyceride, high density lipoprotein (HDL), low density lipoprotein (LDL), blood pressure, and pulse rate) from 515 articles. Results: One-group pretest-posttest design was the most common. The main physical activity was an aerobic exercise. Five of 14 studies reported a significant improvement of total cholesterol. Four of 14 studies found relationship between exercise and triglyceride. Eight of 12 studies reported a significant improvement of HDL, whereas 3 of 9 studies reported a significant improvement of LDL. In over 60% of selected studies, reported significant improvement of blood pressure. Conclusion: Based on the review, it suggests that regular physical activity of the elderly may improve cardiovascular outcomes.

This study was conducted to figure out the differences of the BMI, blood lipids, blood pressure and nutrient intakes by serum insulin concentration among adults in Korea. Ninety-three subjects(male : n=37, female : n=56) participated in this study. The subjects were grouped by serum insulin concentrations into two groups-hyperinsulinemia group(n=17) and normoinsulinemia group(n=76). Anthropometric measurements, blood lipid profiles, blood pressure, oral glucose tolerance test, and daily nutrient intakes were analyzed. And serum glucose and insulin secretion pattern as shown through and oral glucose tolerance test were performed. BMI (p<0.05) and WHR(p<0.01) were significantly higher in hyperinsulinemic group than in normoinsulinemia group. There was no differences in fasting blood glucose level between groups, but total glucose area (p<0.001) and insulin glucose resistance(p<0.001) were significantly higher in hyperinsulinemia group than in normoinsulinemia higher in hyperinsulinemia group, but HDL-cholesterol(p<0.05), and systolic blood pressure(p<0.05) were significantly higher in hyperinsulinemia group, but HDL-cholesterol(p<0.001) was significantly lower in hyperinsulinemia group. They showed significant differences in energy, carbohydrate, potassium, riboflavin, niacin and dietary fiber intakes(p<0.05), the intake of those nutrients were low in normoinsulinemia group. Further investigation is necessary to determine the effects of amounts and types of carbohydrate and dietary fiber on serum insulin concentrations.

Both hydrolysed guar gum and polydextrose have been used as a major fiber source in preparations of unctional drink products and other food products. In this study we determined the effects of these fibers on lipid metabolism of normal rats with two different dietary fat levels by using cellulose as the control. Serum total lipid triglyceride total cholesterol and HDL-colesterol were determined with proper enzymatic methods. Feed intake weight gain and feed efficiency ratio were also calcula-ted. Polydextrose-fed group showed lower serum triglyceride level than hydrolysed guar gum-fed group regardless of fat level used in this study without changing total lipid level in the serum. We also observed that polydextrose-fed group showed low serum cholesterol level nummerically high serum HDL-cholestrol level and more excretion of fecal neutral sterols when compare with those values of hydrolysed guar gum-fed group. The results indicate that polydextrose might have more beneficial roles in lipid metabolism when compare with hydrolysed guar gum.

This study was conducted to investigate effects of dietary anthocyanin fortified barley (AFB) or whole crop barley (WCB) on growing performance, meat quality and blood properties in swine at late fattening phase. Swine performance was not significantly differed (p>0.05) but average daily gain and average daily feed intake tended to increase in treatments. Meat quality parameters including pH, cooking loss, shear force and meat surface color were not influenced by the addition of barley in diet. However, DPPH content of longgissmus dorsi muscle was significantly increased in WCB10 compared to control, AFB5 and WCB5 (p<0.05). FRAP content of longgissmus dorsi muslce was higher in WCB5 than the AFB (p<0.05), thereby, a tendency in FRAP was not similar to that of DPPH. Only myristic acid (C14:0) was affected, and the lowest myristic acid was found when AFB was supplied to swine. A tendency was not determined in total protein and HDL-cholesterol content, however, control, WCB10 and AFB5 had high in total protein and showed significantly low values in HDL-cholesterol. Therefore, the results indicate that barley can be considered as an ingredient in swine diet, but further investigation is necessary.

Objective: Growing evidence suggests that increased cardiovascular disease (CVD) risk is associated with female infertility caused by conditions such as polycystic ovarian disease, obesity, thyroid dysfunction, and endometriosis. The aim of this study was to evaluate whether any relationship exists between CVD and unexplained infertility. Methods: Sixty-five women with unexplained infertility and 65 fertile controls were enrolled in the study. CVD risk markers such as low-density lipoprotein (LDL), high-density lipoprotein (HDL), total cholesterol (TC), triglycerides (TG), insulin resistance (defined by the homeostasis model assessment ratio), and high-sensitivity C-reactive protein (hs-CRP) were assessed. Results: TG, TC, LDL, and hs-CRP levels were higher and HDL levels were lower in patients with unexplained infertility than in fertile controls (p<0.05 for all). Positive associations were found between unexplained infertility and TG, TC, LDL, and hs-CRP levels, and a negative correlation was found for HDL (p<0.05 for all). Multivariate logistic regression analysis showed that TG, HDL, and hs-CRP were independent variables associated with unexplained infertility. Conclusion: Our study showed that women with unexplained infertility had an atherogenic lipid profile and elevated hs-CRP levels, suggesting a higher risk of developing CVD in the future. Further studies with larger groups are needed to investigate the nature of this link.

To examine the effect of Codium fragile on blood cholesterol and lipid metabolism, hyperlipidemia was induced in experimental animal rats through the administration of a hypercholesterolemic diet. Codium fragile powder was then administered to the rats for 5 weeks, after which, blood biochemical changes such as blood cholesterol, Aspartate Aminotransferase (AST: serum SGOT) and Alanine Aminotransferase (ALT: serum SGPT) enzyme activity, etc. were determined. And histological changes in liver cells were examined using an electron microscope. Codium fragile treatment resulted in a significant reduction of the levels of total cholesterol, blood triglyceride and low-density cholesterol (LDL. Chol) compared to the control rats. In contrast the expression levels of high-density cholesterol (HDL. chol.) were increased. The AST value of the Codium fragile administration group was significantly reduced and the blood ALT value of the Codium fragile group showed a significant decrease in comparison to the negative control group. In summary, this study demonstrated the beneficial possibilities of Codium fragile in improving the abnormality of lipid metabolism caused by liver cell damage and hyperlipidemia.

This study was conducted to investigate the effects of shellfish hydrolysate on lipid metabolism in rats fed high fat diet. Male Sprague-Dawley rate weighting approximately 110g were fed basal control diet, high fat diet and high fat diet plus 4 different shellfish hydrolyates for 4 weeks. The shellfish hydrolysates from the different sources, were oyster, hard-shelled mussel, little neck clam and march clam. After 4 weeks, serum GOT, GPT, ${\gamma}$-GTP, triglyceride and total cholesterol was significantly decreased in shellfish hydrolysates supplementation with high fat diet compared to basal control and high-fat group(p<0.05). The total lipid and cholesterol content in liver showed significant decrease(p, 0.05). There were no different in serum GPT, HDL-cholesterol, liver total cholesterol and lipid of rats between basal control diet and high-fat diet. The unsaturated fatty acids, specific components of shellfishes were a little components in shellfish hydrolysate as they were a low and not different among the groups and were most well reflected in liver and plasma. Considering digestive and absorptive process of in human body, it was assumed that the hypolipidemic effect of shellfish was not under the influence of unsaturated fatty acids but the other components, peptides, taurine and betaine and so on was detected in the process of hyperlipidemia induced by high-fat diet.
