BACKGROUND Hypercholesterolemia is characterized by a coronary vasoconstrictive response to the endothelium-dependent vasodilator acetylcholine. This abnormality may be due to reduced synthesis of endothelium-derived relaxing factor and/or enhanced synthesis and release of an endothelium-derived contracting factor. Endothelin is an endothelium-derived vasoconstrictor and mitogenic peptide that ...

BACKGROUND Our study used data collected in Chung-Shing-Shin-Tseun community in Taiwan in May 1998 to evaluate the relationship between hypercholesterolemia and the cardiovascular and sociodemographic risk factors in elderly people. METHODS Individuals aged 65 and over were recruited as study subjects. A total of 1,093 persons, out of 1,774 registered residents, were contacted in face-to-face...

Prague hereditary hypercholesterolemic (PHHC) rat - rat strain crossbred from Wistar rats - is a model of hypercholesterolemia induced by dietary cholesterol. Importantly, no bile salts and/or antithyroid drugs need to be added to the diet together with cholesterol to induce hypercholesterolemia. PHHC rats have only modestly increased cholesterolemia when fed a standard chow and develop hyperch...

INTRODUCTION AND OBJECTIVES Familial hypercholesterolemia and familial defective Apo B-100 are phenotypically indistinguishable. At present they can be distinguished by genetic analysis. PATIENTS AND METHODç We compared the clinical features of 13 subjects with familial defective Apo B-100 and 39 subjects with familial hypercholesterolemia. We used data from first degree relatives to compare mo...

Patients with familial hypercholesterolemia have elevated levels of plasma low density lipoproteins (LDL), increased hepatic synthesis of apolipoprotein B-containing lipoproteins, defective binding of low density lipoproteins to fibroblasts, and premature atherosclerosis. The role of a hepatic low density lipoprotein receptor in normal man and its importance in the pathogenesis of familial hype...

objective(s): we examined the effects of endurance exercise in the presence of bunium persicum extract administration on lipid profile and cardiorespiratory capacity in hypercholesterolemic male mice. materials and methods: forty male hypercholesterolemic mice were divided into four groups: vehicle, endurance exercise (ee), bunium persicum extract (bpe), and ee + bpe. the exercise protocol was ...

we aimed to evaluate the potential of growing rats as a model of osteoporosis induced by short term hypercholesterolemia. twelve growing female sprague-dawley rats were randomly allocated into two groups. control rats received standard diet while rats in group 2 were fed with diet contained 20% sunflower oil, 2% cholesterol and 0.5% cholic acid for 2 weeks and then a diet contained 10% sunflowe...

Background. Hypercholesterolemia is characterized by a coronary vasoconstrictive response to the endothelium-dependent vasodilator acetylcholine. This abnormality may be due to reduced synthesis of endothelium-derived relaxing factor and/or enhanced synthesis and release of an endothelium-derived contracting factor. Endothelin is an endothelium-derived vasoconstrictor and mitogenic peptide that...

Familial hypercholesterolemia (FH), caused by a defect in the low density lipoprotein (LDL) receptor, results in high plasma concentrations of LDL cholesterol due to both overproduction and delayed catabolism of LDL FH is also associated with significantly lower levels of plasma high density lipoprotein cholesterol and apolipoprotein (apo) A-I in both heterozygous and homozygous patients. Howev...
