the present investigation was undertaken to evaluate the effect of antihypertensive drugs on aortic atherogenesis in hypercholesterolemic rabbits. in enalapril and nifedipine treated rabbits aortic atherosclerotic plaque involvement was significantly decreased (p<0. oland p

Pleurotus citrinopileatus is a popular edible mushroom in Korea due to their bright color, unique flavor and texture. This study was initiated to evaluate the effects of feeding dietary P. citrinopileatus fruiting bodies on plasma and feces biochemical and on the liver histopathology in hypercholesterolemic rats. Six-week old female Sprague-Dawley albino rats were divided into three groups of 1...

BACKGROUND Hypercholesterolemia impairs endothelium-dependent dilation in arteries. We tested the hypothesis that hypercholesterolemia impairs endothelium-dependent vasodilation by an interaction between elevated plasma lipoproteins and a presumably normal endothelium using human veins in vivo; veins do not generally develop atherosclerosis and are appropriate for testing functional alterations...

BACKGROUND Hypercholesterolemia is among the most common health problems treated with traditional remedies. Nigella sativa (NS) is an effective plant for treating hypercholesterolemia. However, the effects of this herb on hematologic factors and hemostasis system have not been elucidated. This study was designed to investigate the effects of NS on these factors in both normal and hypercholester...

OBJECTIVE Arachidonic acid (AA) metabolites from 15-lipoxygenase-1 (15-LO-1), trihydroxyeicosatrienoic acid (THETA), and hydroxyepoxyeicosatrienoic acid (HEETA) relax arteries. We studied 15-LO-1 expression, THETA and HEETA synthesis, and their effect on arterial relaxations and blood pressure in hypercholesterolemic nonatherosclerotic rabbits. METHODS AND RESULTS Immunoblots, RTPCR analysis,...

We studied cholesterol metabolism in experimental xanthoma tissues which were induced by injection of high molecular weight sodium dextran sulfate into the dermis of hypercholesterolemic rabbits. Control studies were performed on dermal specimens of the dextran sulfate-injected site of normolipemic rabbits. Cholesterol accumulation was much greater in the hypercholesterolemic rabbit tissues tha...

We hypothesized that normal vascular reactivity could be restored in vessels from hypercholesterolemic animals by exposing them to L-arginine, the precursor of endothelium-derived relaxing factor (EDRF). Basilar arteries were harvested from New Zealand white rabbits fed normal chow or that supplemented with 2% cholesterol for 10 wk. Vessels were cannulated for perfusion at physiologic pressure....

Angiotensin II (Ang II) promotes vascular smooth muscle growth and may be involved in the initiation and progression of atherosclerosis. To examine whether Ang II receptor expression in vascular tissues is altered in atherosclerosis, male New Zealand White rabbits were fed a high-cholesterol diet (1% cholesterol + 4% coconut oil mixed with regular chow; hypercholesterolemic group, n=12) or regu...

BACKGROUND/OBJECTIVES The purpose of the current study was to investigate the effect of red pericarp glutinous rice rich in polyphenols (Jakwangchalbyeo, red rice) on serum and hepatic levels of cholesterol and hepatic protein expression linked to synthesis and degradation of cholesterol in a hypercholesterolemic mice diet as compared with brown rice. MATERIALS/METHODS C57BL/6 male mice were ...
