Inhibition of cholesterol absorption in rats by plant sterols.
The extent and site(s) of inhibition of cholesterol absorption by plant sterols, sitosterol and fucosterol, were studied in rats. The intragastric administration of a single emulsified lipid meal containing 25 mg [3H]cholesterol and 25 mg of either sitosterol or fucosterol inhibited the lymphatic absorption of cholesterol by 57% and 41%, respectively, in 24 hr. Less than 2% of each plant sterol...
متن کاملComparison of effects of dietary unesterified and esterified plant sterols on cholesterol absorption in rats.
Effects of dietary unesterified plant sterols and plant sterol oleates and stearates on absorption and metabolism of cholesterol were compared in rats fed a cholesterol-supplemented diet. Fecal excretion of neutral steroids (cholesterol plus coprostanol) in rats fed unesterified plant sterols or plant sterol oleates was significantly higher than in those fed the control diet or plant sterol ste...
متن کاملDisruption of cholesterol homeostasis by plant sterols.
The ABC transporters ABCG5 and ABCG8 limit absorption and promote excretion of dietary plant sterols. It is not known why plant sterols are so assiduously excluded from the body. Here we show that accumulation of plant sterols in mice lacking ABCG5 and ABCG8 (G5G8-/- mice) profoundly perturbs cholesterol homeostasis in the adrenal gland. The adrenal glands of the G5G8-/- mice were grossly abnor...
متن کاملInhibition of cholesterol absorption and synthesis in rats by sesamin.
The effects of sesamin, a lignan from sesame oil, on various aspects of cholesterol metabolism were examined in rats maintained on various dietary regimens. When given at a dietary level of 0.5% for 4 weeks, sesamin reduced the concentration of serum and liver cholesterol significantly irrespective of the presence or absence of cholesterol in the diet, except for one experiment in which the pur...
متن کاملThe absorption of plant sterols by the fowl.
I. A gas-liquid chromatographic method for the detection of phytosterols in tissues and excreta of birds was developed. The limitations of this method are discussed. 2. pand y-Sitosterol werc detected in the plasma of adult cockerels and in the plasma, intestinal wall, and liver of 4-week-old cockerels. The proportion of sitosterols in the total sterol absorbed appeared to be affected by the na...
