  • Recent studies suggest a possible pathogenic linkage between the osteoporosis and atherosclerosis. We investigated the relationship between cardiovascular risk factors, including high sensitivity C-reactive (hs-CRP), hs-CRP and bone metabolism in females. Anthropometric measurements were performed on 300 women, and cardiovascular risk factors, including fasting blood glucose, lipid profiles and hs-CRP. An atherogenic index was calculated using the serum total cholesterol level divided by the high-density lipoprotein cholesterol level. The lumbar spine bone mineral density was measured using dual X-ray abosorptiometry. By bivariate analysis, the lumbar spine BMD showed negative correlations with age, systolic and diastolic blood pressures, serum total cholesterol, high-density lipoprotein cholesterol. The Age, BMI and high-density lipoprotein cholesterol showed significant correlations with the lumbar spine BMD. From linear regression analyses of all the study subjects, age, high-density lipoprotein cholesterol were found to be determinants of the lumbar spine BMD($R^2=0.272$).

  • Purpose: Gardening has been reported to have positive emotional and physical effects in older adults. However, limited studies have assessed this relationship in Korea. Therefore, in this pilot study of densely populated urban dwellers, we aimed to investigate whether temporary but repeated experiences of the natural environment could positively change metabolism-related blood indicators. Methods: This study used pre- and post-interventional designs to investigate the effects of 16 weeks of gardening on lipid profiles in an urban adult population and investigate their relationships. This study was conducted 30 times at the H Botanical Garden in Yongin City from August 16, 2021 to November 30, 2021 (16 weeks, twice a week, 3 hours each time). Before and after the gardening program, a clinical pathologist collected blood samples from the participants. Results: High-density lipoprotein levels increased, low-density lipoprotein levels decreased, and total cholesterol levels decreased after the gardening activity. Conclusions: Our findings suggest that gardening has potential for clinical application as it has good control over the lipid profile through physical activity. These findings can be used as basic data for studying the relationship between urban populations and their living environment and for various studies in the future as experiencing the natural environment provides many health benefits.

  • Effect of saponin fraction of ginseng C.A. Meyer on blood serum lipoprotein distribution of high cholesterol fed rabbits for two to four weeks was investigated. A. significant increase of very low density lipoprotein(VLDL) and low density lipoprotein(LDL) occured while high density lipoprotein(HDL) were decreased in the blood of both groups which were fed high cholesterol diet with (test group) and/or without ginseng saponin(control group) for 2-4 weeks. However the degrees of VLDL and LDL increase and HDL decrease were relatively small in ginseng administered group compared with control group. This suggests that the hypocholesterolemic action of the saponin might be brought about by decreasing the raised VLDL and LDL level and increasing the lowered HDL level.

  • The development of radioimmunoassay (RIA) for high-density lipoprotein (HDL) in Japanese quail serum will contribute to the screening of drugs acting on cholesterol transport. We have developed a double antibody RIA method for J. quail HDL. The first antibody was raised in rabbit by immunization of HDL isolated by the dextrane sulfate-$Mn^{#}$ precipitation method. For the preparation of raclioiodinated antigen, HDL was further purified by combination of electrophoretic procedure. Using the second antibody raised in goat by rabbit IgG, we have furnished the RIA method for HDL. It showed high specificity and sensitivity of working assay range, 0.1-33.mu.g HDL/tube. There was no correlation between the radioimmunoassay of HDL and the enzyme assay of HDL-cholesterol.

  • Dyslipidemia in nephrotic syndrome (NS) is often characterized by marked increases in the levels of total cholesterol, triglycerides, low-density lipoprotein cholesterol, and other lipoproteins, such as very low-density lipoprotein, intermediate-density lipoprotein, and lipoprotein(a). It has been suggested that impaired catabolism of lipoproteins and cholesterol is mainly due to decreased lipoprotein lipase and hepatic lipase activity, and increased biosynthesis of lipoproteins in the liver. The management strategies for dyslipidemia in patients with NS consist of lifestyle modification, lipid-lowering agents represented by statins, second-line agents such as fibrates and bile acid sequestrants, and lipid apheresis. Compared with dyslipidemia in adult NS patients, whose risks of atherosclerotic disease and progressive renal injury are considered high, clinical data on dyslipidemia in pediatric NS patients are limited. Therefore, it is necessary to pay more attention to the evaluation and management of dyslipidemia in pediatric patients with NS in clinical practice.

  • High-density lipoprotein (HDL) is a proven biomarker for the monitoring of changes in antioxidant and anti-inflammation capability of body fluids. The beneficial virtues of HDL are highly dependent on its lipids and protein compositions, and their ratios. In normal state, the HDL particle is enriched with lipids and several HDL-associated enzymes, which are responsible for its antioxidant activity. Lower HDL-cholesterol levels (<40 mg/dL) have been recognized as an independent risk factor for coronary artery disease, as well as being a known component of metabolic syndrome. Functional and structural changes of HDL have been recognized as factors pivotal to the evaluation of HDL-quality. In this review, I have elected to focus on the functional and structural correlations of HDL and the roles of HDL-associated apolipoproteins and enzymes. Recent clinical applications of HDL have also been reviewed, particularly the therapeutic targeting of HDL metabolism and reconstituted HDL; these techniques represent promising emerging strategies for the treatment of cardiovascular disease, for drug or gene therapy.

  • Purpose: The aim of this study was to evaluate the serum levels of oxidized low-density lipoprotein (oxLDL), anti-oxLDL, and myeloperoxidase (MPO) in hyperlipidemic patients with periodontal disease. Methods: This study included 123 patients with hyperlipidemia categorized based on metabolic control as mild to moderate (H1) (n=66) or poor (H2) (n=57), as well as systemically healthy controls (C) (n=68). Serum levels of lipids, oxLDL, anti-oxLDL, and MPO were evaluated, along with clinical periodontal parameters. Results: The percentage of bleeding on probing (BOP%) and the clinical attachment level were significantly higher in the H2 group than in the C group. Patients with hyperlipidemia had a relatively high risk of developing periodontal disease. The oxLDL and anti-oxLDL levels were higher in H2 patients with periodontitis than in the control or H1 patients with periodontitis. In the H1 and H2 groups, the ratio of total cholesterol to high-density lipoprotein was significantly correlated with gingival index, BOP%, and oxLDL levels. Conclusions: Our findings indicate that the lipoprotein-associated inflammatory mediators of oxLDL, anti-oxLDL, and MPO may play an important role in the relationship between periodontal disease and hyperlipidemia.

  • Patients with hemorrhagic fever with renal syndrome (HFRS) often exhibit altered serum lipid and lipoprotein profile during the oliguric phase of the disease. Serum lipid and lipoprotein profiles were assessed during the oliguric and recovery phases in six male patients with HFRS. In the oliguric phase of HFRS, the apolipoprotein (apo) C-III content in high-density lipoproteins (HDL) was elevated, whereas the apoA-I content was lowered. The level of expression and activity of antioxidant enzymes were severely reduced during the oliguric phase, while the cholesteryl ester transfer protein activity and protein level were unchanged between the phases. In the oliguric phase, electromobility of $HDL_2$ and $HDL_3$ was faster than in the recovery phase. Low-density lipoprotein (LDL) particle size was smaller and the distribution was less homogeneous. Patients with HFRS in the oliguric phase had severely modified lipoproteins in composition and metabolism.

  • Purpose: The purpose of this study was to examine the effect of a 8-week dynamic yoga program on body composition and blood lipids in middle-aged post-menopausal women. Method: Twenty participants were allocated to the yoga group (YG, n=10) or the control group (CG, n=10). They were assessed for lean body mass, percent body fat, waist to hip ratio, total cholesterol, low density lipoprotein cholesterol, high density lipoprotein cholesterol, and triglyceride both before and after intervention. The yoga group participated in the program lasting $50{\sim}60$ minutes, five times a week for 8 weeks. Results: Unlike the control group, the yoga group showed a significant decrease in total cholesterol, low density lipoprotein cholesterol, percent body fat, and waist hip ratio after the yoga training. However, changes in lean body mass, high density lipoprotein cholesterol, and triglyceride level during the intervention period were not different between the yoga group and the control group. Conclusion: The 8-week dynamic yoga program could be adopted to prevent cardiovascular diseases in middle-aged post-menopausal women by promoting body composition & blood lipids.

  • The purpose of this study was to investigate the effect of Schizandra chinensis extract on the serum and hepatic lipids inhyperlipidemic rats fed with high-fat diet. The Schizandra chinensis extract decreased significantly in total serum cholesterol, serum triacylglycerol and heptic triacylglycerol but not in the total hepatic cholesterol. The Schizandra chinensis extract also decreased in very low density lipoprotein increased by the highfat diet without affecting high density lipoprotein cholesterol. These results suggest that Schizandra chinensis extract may be benificial for the regulation of hyperlipidemia.
