High serum cholesterol level is a major risk factor for coronary heart disease(CHD). Nutrition therapy of hypocholesterolemic diets with increased physical activity is the essential step in the treatment of the hypercholesterolemic patients. The purpose of this study was to evaluate the short-term effect of intensive dietary therapy combined with regular exercise in lowering serum cholesterol level. Seventy three hypercholesterolemic outpatients(mean: 268.0$\pm$24.7mg/dL), aged 34 to 73(mean: 56$\pm$9.8yrs), who visited cardiology OPD of Yonsei Cardiovascular Center from April through October, 1998 were studied. Anthropometric measurements, usual nutrient intake survey using semiquantitative food frequency questionnaire, and daily nutrient intake analysis were performed. The nutrition counseling for the hypocholesterolemic diet and exercise therapy was performed individually. After a 4 week intensive dietary therapy, comparisons of body weight, nutrient intakes, and blood lipid concentrations were evaluated for the hypocholesterolemic effect of intensive diet therapy. After 4 weeks of intensive diet therapy, significant reductions in percent ideal body weight(p<0.01), saturated fat intake(p<0.01), and cholesterol intake(p<0.01) were observed. There were significant reductions in serum total cholesterol and LDL-cholesterol levels after 4 weeks of therapy by 8.1%(p<0.01) and 9.7%(p<0.01), respectively. Our results showed that intensive dietary therapy was effective in reductions of serum total and LDL-cholesterol levels. The goal for this dietary modification should not be temporary but rather be permanent in eating behavior accompanied by appropriately increased physical activity.

This study demonstrates that red yeast rice exhibits radical scavenging and antihypercholesterolemic activities in rats fed cholesterol. Sprague-Dawley male rats were divided to five dietary groups (normal, chol-control; and M-1, M-2 & M-3 administered 150, 300, and 500 mg/kg red yeast rice, respectively) and fed their respective diets for 4 weeks. No significant differences in food efficiency ratio (FER) were found among the five groups. The weight of perirenal fat pads decreased with increasing amounts of red yeast rice supplementation. There was a significant decrease in the levels of cholesterol in M-3 group fed red yeast rice with 500 mg/kg compared to those in the chol-control, M-1 and M-2 groups (p<0.05). Among the rats fed the cholesterol-enriched diet, all groups fed red yeast rice showed higher concentration of the HDL cholesterol, but lower concentration of the LDL cholesterol than those of the chol-control group. The scavenging activity of the methanol extract from red yeast rice was increased with increasing amounts of the extract. The glutathione content in the normal group and in the M-3 group were higher than that in the other groups. The M-3 group showed similar hepatic glutathione contents to those of the normal group. These results suggest that red yeast rice may be safe and effective for lowering serum levels of total and LDL-cholesterol, ratio of non-HDL/HDL, and severity of experimental atherosclerosis.

The objective of this study was to evaluate the effects of Lactobacillus acidophilus ATCC 43121 and L. fermentum MF27 on biochemical indices in the serum, cholesterol metabolism in the liver and mucin expression in the gallbladder in lithogenic diet (LD)-induced C57BL/6J mice to determine the preventive effects of lactobacilli on gallstone formation. By the end of 4 wk of the experimental period, mice fed on a LD with high-fat and high-cholesterol exhibited higher levels of total and low-density lipoprotein cholesterol in the serum compared to mice fed on control diet or LD with L. acidophilus ATCC 43121 (LD+P1; p<0.05). Cholesterol-lowering effects observed in the LD+P1 and LD with L. fermentum MF27 (LD+P2) groups were associated with reduced expression of 3-hydroxy-3-methylglutaryl coenzyme A reductase in the liver compared to the LD group (p<0.05). Furthermore, expression of the gel-forming mucin, including MUC5AB and MUC5B, was suppressed in the LD+P1 and LD+P2 groups compared to the LD group (p<0.05). Therefore, steady intake of both L. acidophilus ATCC 43121 and L. fermentum MF27 may have the ability to prevent the formation of cholesterol gallstones in LD-induced C57BL/6J mice.

복분자 미숙과 물추출물이 콜레스테롤 개선에 미치는 영향을 측정한 결과는 다음과 같다. 간세포주(HepG2 cells)에서 복분자 미숙과 물추출물은 SREBPs를 증가시킴으로써 혈액 내에 LDL을 LDL receptor를 통해서 세포 안으로 흡수시키고, 콜레스테롤 합성에 관여하는 HMG-CoA reductase 활성을 억제하면서 체내 콜레스테롤을 조절하였다. 그러나 HDL의 생성에 관여하는 유전자(ABCA1, SR-B1)는 변화를 보이지 않았다. 결과적으로 복분자 미숙과 물추출물이 LDL receptor를 통해서 LDL을 억제시키고 체내에서는 콜레스테롤 생합성을 억제하였으며, HDL의 생성에는 관여를 하지 않음을 확인하였다. 또한 ApoB1/ApoA1 ratio 값을 통해서 동맥경화 지표를 확인해 본 결과 유의성 있게 수치가 감소함을 확인하였고, 이는 미숙과 물추출물이 콜레스테롤을 개선하여 동맥경화를 예방할 것으로 기대한다. 또한 대식세포(RAW 264.7 cells)에서 복분자 미숙과 물추출물이 CD 36, SR-A 수용체를 억제시킴으로 인해 세포 내의 ox-LDL 의 흡수를 차단시키고, 세포 안에서는 macrophage에 있는 PPAR-${\gamma}$를 억제시킴으로 인해 LDL 산화가 억제되었다. Adipophilin의 활성이 억제됨에 따라 세포 안에 있는 콜레스테롤 방출을 촉진시킴으로 인해 동맥경화를 완화시킬 수 있다고 사료된다.

Dyslipidemia is the multiple lipid metabolic disorders which is one of the high risk factors for the atherosclerotic diseases. It increases the morbidity and mortality and therefore, must be treated with antilipidemic agents. HMG-Co A reductase inhibitors (statins), one of many antidyslipidemic agents, have shown to be significant improvement from the various cholesterol levels. Especially, data from many comparative trials suggest that rosuvastatin is more effective than atorvastatin among many other statins. The aims of this study were to evaluate the efficacy and safety between rosuvastatin and atorvastatin in the treatment of Korean patients with dyslipidemia. Currently the Korean Society of Lipidology and Atherosclerosis based on the Korean health screening data suggests that Korean patients with dyslipidemia should be treated by the target cholesterol levels according to the Adult Treatment Panel III guidelines of the US National Cholesterol Education Program (NCEP-ATP III). We reviewed retrospectively all medical histories of the total 392 dyslipidemic patients with atorvastatin or rosuvastatin from June 1st, 2004 to August 31st, 2006 in Chungbuk National University Medical Center. Patients were classified as total 4 groups by the NCEP-ATP III Guidelines. The numbers of enrolled patients were each 5 mg atorvastatin (n=34), 10 mg atorvastatin (n=148), 5 mg rosuvastatin (n=94) and 10 mg rosuvastatin (n=82). In comparison between groups, rosuvastatin groups in the lowering LDL-C had better efficacies, and the results were each 22% (5 mg atorvastatin), 33.3% (10 mg atorvastatin), 35% (5 mg rosuvastatin) and 41.3% (10 mg rosuvastatin) with the dose relationship (P=0.000). Rosuvastatin groups also have shown to be more significantly reducing Total Cholesterol levels compared to atorvastatin groups with the no dose relationship (P=0.000). In the lowering of non-HDL cholesteroles, rosuvastatin groups showed significantly better efficacies than atorvastatin with the dose-relationship (P=0.000). Each medication groups did not demonstrate the differences in the changing of HDL cholesterol and triglyceride levels (P=0.096, 0.309, respectively). In conclusion, rosuvastatin was better efficacious than atrovastatin in reducing LDL-C Total Chol, and Tg. Therefore, rosuvastatin is a good antilipidemic agents for Korean patients with dyslipidemia and it can use to minimize the morbidity and mortality related to the cardiovascular diseases in Korean.
