Atherosclerosis is a chronic inflammatory disease and represents the major cause of cardiovascular morbidity and mortality. A critical regulator of inflammatory processes represents the mitogen-activated protein kinase-activated protein kinase-2 (MK2). Therefore, we investigated the functional role of MK2 in atherogenesis in hypercholesterolemic mice as well as potentially underlying mechanisms...

We examined effects of hypercholesterolemia and atherosclerosis on vasoconstrictor responses to norepinephrine and serotonin. Responses were compared in normal, atherosclerotic, and hypercholesterolemic but non-atherosclerotic cynomolgus monkeys. The hindlimb was perfused at constant flow so that changes in perfusion pressure indicated changes in vascular resistance. We measured the pressure gr...

The effect of diet-induced, moderate elevation of serum cholesterol on vascular reactivity in isolated rabbit abdominal aortic rings was examined by using a series of vasoconstrictor and vasodilator agonists. Serum cholesterol of rabbits that were fed a cholesterol-free, casein-rich diet for 10 weeks was elevated approximately 4.5-fold compared with values found in control rabbits that were fed...

BACKGROUND Basic fibroblast growth factor (bFGF) promotes vascular repair and angiogenesis and can induce in vitro tissue factor (TF), a potent agent initiating thrombogenesis, which probably plays a role in angiogenesis. We investigated whether bFGF administration induced TF expression by monocytes and vascular cells. METHODS AND RESULTS We studied TF expression in normally fed (n=16) and ch...

This work was conducted to investigate dietary supplementation of oyster mushroom fruiting bodies on biochemical and histological changes in hyper and normocholesterolemic rats. Six-week old female Sprague-Dawley albino rats were divided into three groups of 10 rats each. Feeding a diet containing a 5% powder of Pleurotus ostreatus fruiting bodies to hypercholesterolemic rats reduced plasma tot...

Hyperlipidemia plays an important role in the development of atherosclerosis, the main cause of death in the world. In this study, the lipid-lowering effect of Carica papaya leaf in rats fed with a high cholesterol diet was evaluated. Daily doses of C. papaya extract 0, 31, 62 or 125 mg/kg body weight were orally administered in 300 μl polyethylene glycol to hypercholesterolemic rats; it was al...

Hypercholesterolemia is commonly associated with obesity that leads to heart diseases and diabetes. The hepatocardioprotective activity of parsley and carob methanol extract was tested in hypercholesterolemic male rats. Twenty-four male albino rats were divided into four groups (n = 6). Group 1 was the negative control group fed with fat rich diet, group 2 (G2) was hypercholesterolemic rats fed...

A B S T R A C T The effect of cholestyramine on the fecal excretion of bile acids and neutral sterols was measured in a hypercholesterolemic patient on a low fat, high polyunsaturated fatty acid-containing diet after the intravenous injection of cholesterol4-14C. A significant (16%) lowering of serum cholesterol concentration was accompanied by a 3.2-fold increase in fecal bile acid excretion b...

The aim of our study was to compare the effect of simvastatin on systemic inflammation and monocyte secretory function between subjects with impaired glucose tolerance (IGT) and isolated hypercholesterolemia. We studied 26 patients with isolated IGT and 24 subjects with primary hypercholesterolemia, who were treated for 12 weeks with 20 mg of simvastatin daily. Plasma lipids, fasting and 2-h po...
