conclusions decreases of tc, ldl and tg may be related to tomato antioxidant effect. this course in human required more investigations. results results showed that in chol group, all lipids increased significantly (p < 0.05) except hdl compared to the control group. tomato and tomato paste supplementation decreased tc, ldl and tg concentration significantly (p < 0.05) compared to chol group. to...

In 3 healthy male physicians a reduction of dietary fat produced a significant fall in the serum cholesterol concentration. Subsequently, when a diet containing normal quantities of fat but very low in cholesterol was taken, a rise in serum cholesterol concentration occurred in all 3 subjects. W HILE controversy has long prevailed concerning the possibility of lowering serum cholesterol by regu...

Low concentrations of cyclodextrins (< 1.0 mM) added to serum act catalytically, accelerating the exchange of cholesterol between cells and lipoproteins. J774 macrophages incubated with serum and 2-hydroxypropyl-beta-cyclodextrin (< or = 1 mM) released fivefold more labeled cholesterol than with serum alone. Increased efflux was not accompanied by a change in cell cholesterol mass; thus, cyclod...

the effects of ethanolic and aqueous extracts of rheum ribs l. (rr) of the family polygonaceae was studied on serum cholesterol concentration in rabbits. to induce hypercholesterolemia, 0.5 g/kg/day of pure cholesterol powder was given orally to each rabbit for two weeks then cholesterol was halved and each group of animals was treated with a different regimen for another two weeks. both the et...

T he efforts of the National Cholesterol Education Program (NCEP) and the American Heart Association (AHA) to inform the public about the role of cholesterol in coronary heart disease (CHD) have recently come under criticism. The critics, popular magazine writers and a small group of physicians, suggest that the relation between cholesterol and CHD is not well defined, that lowering serum chole...

Several human studies have shown an inverse relation between vitamin A intake (and serum concentrations of retinol and carotene) and cancer. Serum cholesterol concentrations have also been reported in inverse relation to cancer. In a study of 3102 people in Evans County, Georgia, who were followed for over 12-14 years to assess the incidence of cancer there was an inverse association between th...

The power of serum lathosterol concentration as an indicator of whole-body cholesterol synthesis was investigated in 47 human volunteers consuming two diets differing in fatty acid composition. The cholesterol balance (fecal excretion of neutral and acid steroids minus cholesterol intake) was strongly correlated with the serum level of total (free plus esterified) lathosterol and also with the ...
