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.

The six phenolic compounds isolated from the root of Dipsacus asper, 3,4-di-O-caffeoylquinic acid (1), methyl 3,4-di-O-caffeoyl quinate (2), 3,5-di-O-caffeoylquinic acid (3), methyl 3,5-di-O-caffeoyl quinate (4), 4-5-di-O-caffeoylquinic acid (5), methyl 4,5-di-O-caffeoyl quinate (6) were continuously evaluated for their antioxidant activity using superoxide radical scavenging and AAPH-mediated (LDL) oxidation assay. The results demonstrated that compounds 1 - 6 had remarkable antioxidant activities with the $IC_50$ values ranging from 12.0 to $2.8{\mu}M$ in superoxide radical scavenging. They also inhibited AAPH-mediated low-density lipoprotein LDL oxidation by the generation of thiobarbituric acid reactive substances (TBARS) with $IC_50$ ranging from 6.7 to $8.7{\mu}M$.

Sachil-Tang (SCT) has been traditionally used as a prescription of spasm of the esophagus by stress, pectoralgia and oppressive feeling of the chest in Oriental medicine. This study was carried out to investigate the antioxidant activities of the ethanol extract of SCT and its inhibitory effect on intracellular oxidation and vascular cell adhesion molecule-1 expression in human umbilical vein endothelial cells (HUVECs) using various methods. The SCT extract showed a strong inhibitory effect on free radical generating model systems, including DPPH radical, superoxide anions, hydroxyl radical, peroxynirite and nitric oxide. Besides, the SCT extract exhibited a strong inhibitory effect on lipid peroxidation in rat liver homogenate induced by $FeCl_2$-ascorbic acid, and protected plasmid DNA against the strand breakage in a Fenton's reaction system. The SCT extract also inhibited copper-mediated oxidation of human low-density lipoprotein (LDL), and repressed relative electrophoretic mobility of LDL. Furthermore, the SCT extract protected intracellular oxidation induced by various free radical generators and inhibited expression of vascular cell adhesion molecule-1 (VCAM-1) in HUVECs. These results suggest that SCT can be an effective natural antioxidant and a possible medicine of atherosclerosis.

Familial hypercholesterolemia (FH) is a genetic disease that is not well known or diagnosed in Korea. This disease is associated with persistently high levels of low-density lipoprotein cholesterol (LDL-C), which increase the risk of coronary artery disease at a young age. Therefore, early diagnosis and treatment are important; however, there are no global consensus diagnostic criteria. In Korea, the Dutch Lipid Clinic Network diagnostic criteria, and the Simon Broome diagnostic criteria were used for diagnosis of FH according to the agreement announced at the Korean Society of Lipid and Atherosclerosis (KSoLA) in 2022. Recently, the absence of coronary artery calcification has been considered a good prognostic factor, even among patients with very high LDL-C levels who are considered to be at high risk for atherosclerotic cardiovascular disease. We describe throughout this paper the diagnosis and treatment of FH in a young male without coronary artery calcification.

The purpose of this study was to determine whether vitamin {TEX}$B_{6}${/TEX} deficiency and age affect the blood cho-lesterol profile in exercising rats. Fifty four rats were fed either a viramin {TEX}$B_{6}${/TEX} deficient dief(-{TEX}$B_{6}${/TEX}) of a control diet(+{TEX}$B_{6}${/TEX}) for 6 weeks, then subdivided into 3 groups:non-exercise group(NE), exercise and sacrifice group(ES), exercise and recuperation group(ER). ES group was exercised in treadmill({TEX}$10^{o}${/TEX}, 0.5~0.8km/h) for 2 hours and sacrifice. ER group was recuperated three days with respective diet after exercise. At week 3 and 6, and level of plasma total cholesterol(TC), high density lipoprotein cholesterol(HDL_C) and low density lipoprotein cholesterol(LDL_C) were compared. In NE group, there was no difference in the levels of TC, HDL_C and LDL_C between +{TEX}$B_{6}${/TEX} rats and -{TEX}$B_{6}${/TEX} rats. The plasma levels of TC and LDL_C of 6 weeks were higher than those of 3 weeks and on difference in HDL_V between 3 weeks rats and 6 weeks rats. In ES group, there was also no difference in the levels of TC, HDL_C and LDL_C between +{TEX}$B_{6}${/TEX} rats and -{TEX}$B_{6}${/TEX} rats and there was no difference in TC, LDL-cholesterol between 3 weeks rats and 6 weeks rats. The level of HDL_C pf 6 weeks was lower than that of 3 weeks rats. In ER group, there was no difference in the levels of TC and LDL_C not only between +{TEX}$B_{6}${/TEX} rats and-{TEX}$B_{6}${/TEX} rats but also between 3 weeks rats and 6 weeks rats. The level of HDL_C was lower in -{TEX}$B_{6}${/TEX} rats than in +{TEX}$B_{6}${/TEX} rats and higher in 6 weeks rats than in 3 weeks rats. These results suggest that vitamin {TEX}$B_{6}${/TEX} deficiency may affect the HDL_C during exercise and after recuperation. The desirable effect of exercise on plasma Cholesterol profile is strengthened in adult age than young age.

Objectives : The present study was designed to evaluate the protective effect of Allium tuberosum (AT) extract on atherosclerosis in LDL receptor knockout (LDLr KO) mouse fed western diet.Methods : The AT was extracted 70% ethanol. The experimental groups were divided with four groups of LDLr KO mice, one group fed a normal diet and the others fed a Western diets for 8weeks. Two Western diet groups were orally administered AT extract at dosage of 100 and 300 mg/kg body weight. The body weight and food intake were measured every day. We measured levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), triglyceride (TG), total cholesterol (TC), high-density lipoprotein (HDL), low-density lipoprotein (LDL), and Glucose in serum. Also, effect of AT extract performed using H&E staining.Results : The AT treatment groups showed decrease in body weight and food efficiency in comparison with control group. Blood biochemistry parameters such as TG, TC, LDL, and glucose levels were increased in control group, while AT treatment groups were reduced. Also, the increased levels of ALT and AST were improved by AT extract. We confirmed that the weights of liver, kidney, subcutaneous fat, epididymal fat, kidney leaf fat, and intraabdominal fat were change in LDLr KO mice treated AT extract. In addition, histopathological changes in liver and aorta were similar to normal group.Conclusions : Based on these results, the AT extract is considered to make prevention of atherosclerosis through reduction and functional improvement of the liver and vascular endothelial cells in the body fat accumulation and lipid content in LDLr ko mouse model.
