Endothelin-1 (ET-1) signaling mechanisms have been implicated in the pathogenesis of excess coronary artery disease in diabetic dyslipidemia. We hypothesized that in diabetic dyslipidemia ET-1-induced coronary smooth muscle calcium (Ca2+m) and tyrosine phosphorylation would be increased, and the lipid lowering agent, atorvastatin, would inhibit these increases. Male Yucatan miniature swine grou...

Evaluation of the Effect Boron on Histopathological Changes Atherosclerotic Plaque in Aortic Arch and Lipid Profiles Hyperlipidemic New Zealand Male Rabbits

objective: the aim of the present study was to elucidate the possible biochemical improving effect in lipid metabolic that may result from continuous treatment with green tea extract in normal albino rats and those rendered hyperlipidemic by long term supplementation of fat-enriched diet. materials and methods: fifty male albino rats aged six weeks with 200±10 g weight were randomly divided int...

It has been reported that red ginseng acidic polysaccharide (RGAP), isolated from Korean red ginseng, displays immunostimulatory and anti-tumor activities. In a follow-up study, we have carried out a study on the anti-hyperlipidemic effects of RGAP using hyperlipidemic rats acutely induced by Triton WR1339 or corn oil intravenously injected. Oral administration of RGAP (100 to 1000 mg/kg) dose-...

The effects of three Ficus carica leaf extracts on the total cholesterol levels (TC) of serum and liver were investigated in experimentally-induced nutritional hyperlipidemic rats. In nine treatment groups (n=5 each group), hyperlipidemic rats were treated daily with hydromethanolic (total) extract (2.5, 5, 10 mg/kg, intraperitoneal [ip]) and its aqueous fractions, namely fraction A (10, 50, 25...

AIM P wave dispersion (PWD) has been shown to be a noninvasive predictor for the development of atrial fibrillation (AF). Atorvastatin is a 3 hydroxy-3-methylglutaryl coenzyme A (HMGCoA) reductase inhibitor that lowers blood cholesterol levels. The beneficial effect of atorvastatin on atrial arrhythmias is controversial. Aim of this study was to investigate the effect of atorvastatin treatment o...

Hypolipidemic and antioxidant activity profiles of ethanolic extracts of Symplocos racemosa (EESR) were studied by triton-WR1339 (acute) and high fat diet induced (chronic) hyperlipidemic rat models. In both the models, a significant increase in total cholesterol (TC), triglycerides (TG), very low density lipoproteins (VLDL), low density lipoproteins (LDL) and decrease in high density lipoprote...

To investigate the cholesterol-lowering effects of alfalfa saponin extract (ASE) and its regulation mechanism on some key genes involved in cholesterol metabolism, 40 healthy 7 weeks old male Sprague Dawley (SD) rats were randomly divided into four groups with 10 rats in each group: control group, hyperlipidemic group, ASE treatment group, ASE prevention group. The body weight gain, relative li...

Despite the well established correlation between hypercholesterolemia and coronary artery disease (CAD), a substantial body of evidence challenge this relationship. The study aimed to examine whether hyperlipidemia per se constitutes the principal risk factor for atherosclerosis or just a coordinator to other critical mediators. Hyperlipidemia was produced by feeding rats with high-fat diet for...
