  • This study was carried out to investigate the effect of the feeding mixture of linesed oil, rich in n-3 PUFA and the sunflower seed oil, rich in n-6 PUFA on the lipid metabolism in the dietary hypprlidemic rats. After male Sprague-Dawley rats were induced hyperlipidemia by feeding the diet containing lard, butter, and cholesterol for 3 weeks, then they were fed with the diet containing lard 3.0% and butter 12.0% for control, the mixture in different proportion of both linseed oil and sunflower seed oil, and antihyperlipidemic durgs for 2 weeks. Analysis of the lipid component and the fatty acid composition of the liver showed following results. Concentration s of the total cholesterol and phospholipid in liver were significantly higher in group 2 (olive oil 12.0%) and lower in the other groups than in the control group, especially lower in groups 3 (cholestyramine 2.0%) and 9 (sunflower seed oil 12.0%) . Concentration of triglyceride was lower in the other groups except group 4 (liparoid), especially lowe rin group 9 than in the control group. In the fatty acid composition of liver lipids, C18:2 was the major fatty acid. Contents of n-6 PUFA increased , while those of n-3 PUFA decreased in groups composition of the test lipids. From the data on concentration s of total cholesterol. Phospholipid and triglyceride in liver, we concluded that the feeding mixed with 3.0% lard and 12.0 % sunflower seed oil were most effective for the improvement of the live lipids. The fatty acid composition in liver lipids were affected by the fatty acid composition of the test lipids.

  • Objective: This study was conducted to investigate the lipid-lowering effect and safety of Daeshiho-tang in patients with uncontrolled lipid levels by statins. Methods: We investigated patients who had an abnormal lipid profile even when taking statins and who were administered Daeshiho-tang at Kyung-Hee University Korean Medical Hospital for at least one day between January 2008 and December 2018. Their basal characteristics and examinations were reviewed retrospectively with respect to lipid profile, AST, ALT, GGT, BUN, and creatinine. The lipid profile was composed of total cholesterol, triglyceride, LDL-cholesterol, and HDL-cholesterol. Subgroup analysis was performed on each component of dyslipidemia. Results: Among 20 participants, there were 10 males and 10 females. The mean BMI was 23.52. Eighty five percent of the participants were diagnosed as having cerebral infarction. After the administration of Daeshiho-tang, total cholesterol and LDL cholesterol were significantly reduced, to 41.3 mg/dl and 33.95 mg/dl, respectively. In subgroup analyses, total cholesterol and LDL cholesterol were significantly decreased, to 63 mg/dl and 54.6 mg/dl, respectively. Liver and kidney function showed no significant difference after taking Daeshiho-tang. Conclusions: Daeshiho-tang as a decoction or powder had significant lipid-lowering effects on total cholesterol and LDL cholesterol in patients with dyslipidemia. The lipid-lowering effect on total and LDL cholesterol increased in patients with hypercholesterolemia and hyper-LDL-cholesterolemia, respectively. Based on the minimal changes in the liver and kidney function test, Daeshiho-tang would be safe enough to be used in clinics.

  • The effects of red ginseng component (water extracts, alcohol extracts, lipophilic extracts, total saponins, panaxadiol and panaxatriol) administration on glutathione (GSH) and lipid peroxidation levels in mice were investigated. 20~25 g ICR mice which were pretreated with water extracts (50 mg/kg), alcohol extracts (50 mg/kg), lipophilic extracts (50 mg/kg), total saponins (50 mg/kg), panaxadiol (50 mg/kg) and panaxatriol (50 mg/kg) for 15 days. The ability of red ginseng component to protect against oxidative damage to the mouse liver was examined by determining the level of lipid peroxidation (MDA), glutathione, and the activities of glutathione peroxidase (GPX). The GSH level was raised by all the ginseng component, but the GSSG level was lowered ]argely by all the ginseng component. The ratio of GSSG/total GSH was decreased because the level of GSSG was decreased more than that of GSH. Finally, the lipid peroxidation (MDA) level was the lowest in lipophilic extracts and panaxadiol nest. In conclusion, the order of effectiveness of anti-oxidants was to be lipophilic extracts>panaxadiol>total saponins.

  • In the modern era, chronic kidney failure due to diabetes has spread across the globe. Prunetin (PRU), a component of herbal medicines, has a broad variety of pharmacological activities; these may help to slow the onset of diabetic kidney disease. The anti-nephropathic effects of PRU have not yet been reported. The present study explored the potential nephroprotective actions of PRU in diabetic rats. For 28 days, nephropathic rats were given oral doses of PRU (20, 40, and 80 mg/kg). Body weight, blood urea, creatinine, total protein, lipid profile, liver marker enzymes, carbohydrate metabolic enzymes, C-reactive protein, antioxidants, lipid peroxidative indicators, and the expression of insulin receptor substrate 1 (IRS-1) and glucose transporter 2 (GLUT-2) mRNA genes were all examined. Histological examinations of the kidneys, liver, and pancreas were also performed. The oral treatment of PRU drastically lowered the blood glucose, HbA1c, blood urea, creatinine, serum glutamic-oxaloacetic transaminase, serum glutamic pyruvic transaminase, alkaline phosphatase, lipid profile, and hexokinase. Meanwhile, the levels of fructose 1,6-bisphosphatase, glucose-6-phosphatase, and phosphoenol pyruvate carboxykinase were all elevated, but glucose-6-phosphate dehydrogenase dropped significantly. Inflammatory marker antioxidants and lipid peroxidative markers were also less persistent due to this administration. PRU upregulated the IRS-1 and GLUT-2 gene expression in the nephropathic group. The possible renoprotective properties of PRU were validated by histopathology of the liver, kidney, and pancreatic tissues. It is therefore proposed that PRU (80 mg/kg) has considerable renoprotective benefits in diabetic nephropathy in rats.

  • Lipid peroxidation (LPO) has been identified as an important component of atherosclerosis. In this study, the effects of supplementation with cholesterol (0.5%), olive oil (5%) and vitamin E (0.05%) on erythrocyte glutathione (GSH), plasma malondialdehyde (MDA), total cholesterol, HDL-LDL cholesterol and triacylglycerol, brain and liver MDA and GSH concentrations of rats were investigated. A total of 50 Sprague-Dawley male rats aged 6 months, and of equal body weight were used and fed a standard ration ad libitum. Animals were housed in the University of Selcuk, Veterinary Faculty Experimental Animals Unit. The experiment lasted 60 days and there were five experimental groups as follows: 1. Control, 2. Cholesterol (0.5%), 3. Olive oil (5%), 4. Cholesterol plus vitamin E (0.05%), 5. Olive oil plus vitamin E (0.05%). At the end of the experiment, blood samples were taken by cardiac puncture and erythrocyte GSH, plasma MDA, cholesterol, HDL-LDL cholesterol, triacylglycerol and also GSH and MDA concentrations in brain and liver tissue of rats were spectrophotometrically determined. Supplementation of olive oil and cholesterol into rat diets (groups 2 and 3) caused significant differences in lipid parameters; HDL cholesterol concentrations were increased in the olive oil group and LDL cholesterol was lower than in the cholesterol fed group. Moreover, these decreases in LDL and triacylglycerol concentrations were more significant with vitamin E supplementation. The high plasma MDA concentrations showed that lipid peroxidation occurred in the olive oil group and the highest brain MDA concentrations were determined also in the olive oil group. These findings suggest that vitamin E addition may decrease the sensitivities of several oils to oxidation and that monounsaturated fatty acids in olive oil may decrease the incidence of atherosclerosis by regulating blood lipid profiles.
