We supplemented diets with a-tocopheryl acetate (100 mg/kg) and replaced beef tallow (BT) in feeds with increasing doses of n-6or n-3-rich vegetable fat sources (linseed and sunflower oil), and studied the effects on the fatty acid (FA) composition, the a-tocopherol (aT) content and the oxidative stability of rabbit plasma and liver. These effects were compared with those observed in a previous...

BACKGROUND Olive oil's beneficial effects are not only related to its high content of oleic acid, but also to the antioxidant potential of its polyphenols. In this study, we assess the effects of virgin olive oil and its fractions on 2,4-D- induced oxidative damage in the liver of rats. METHODS Male Wistar rats were randomly divided into eight groups of ten each: (C) a control group, (D) grou...

Background : Low vitamin D status is associated with reduced muscle strength, but the benefit of vitamin D supplementation is not clear. Objective : To study whether a daily supplement of vitamin D could improve grip strength. Design : A subtrial of a double-blinded, controlled trial studying the effect of vitamin D on the incidence of hip fractures and other osteoporosis fractures in a frail n...

African green monkeys were fed diets containing either 11% (by weight) fish oil or lard for 2.5 yr. To test the hypothesis that fish oil decreases hepatic secretion of triglyceride (TG) and apoB, livers from these animals were perfused with a fatty acid mixture [85% (w/w) oleate containing [14C]oleate and 15% n-3 containing [3H]eicosapentaenoic acid (EPA)] at a rate of 0.1 mumol fatty acid/min ...

BACKGROUND The pathogenesis of parenteral nutrition (PN)-associated liver dysfunction is multifactorial. Lipid emulsions may be one of the putative mechanisms. Our aim was to comparatively assess the effect of parenteral olive oil- and soybean oil-based lipid emulsions on liver chemistry and bile acid composition in preterm infants. METHODS We performed a double-blind, randomized clinical stu...

This experiment was conducted to evaluate the effects of saturated and unsaturated fats in starter and grower feeds on performance and carcass parts of broilers. In this experiment 288 day old broiler chicks (Ross308 strain) were used in a completely randomized design for 42 days with 8 treatments in 3 replicates and 12 chicks in each replicate. The experimental groups included: T1) control gro...

PURPOSE It was hypothesised that blackcurrant seed oil beneficially modulates metabolic disorders related to obesity and its complications. The study also aimed to investigate the potentially adverse effects of an unbalanced diet on the distal intestine. METHODS Male Wistar rats were randomly assigned to four groups of eight animals each and were fed a basal or obesogenic (high in fat and low...

The cholesteryl ester content of plasma low density lipoproteins (LDL) in monkeys has previously been shown to be related to the rate of hepatic cholesterol secretion and cholesteryl ester content of newly secreted lipoproteins in the isolated perfused liver. In the present studies, African green monkeys were fed diets containing cholesterol and 40% of calories as either butter or safflower oil...

THE absorption spectrum of cod-liver oil possesses a quite special interest because of the fact that the oil contains three known important substances which are sensitive towards light, namely, vitamin A, ergosterol or provitamin D and vitamin D itself. A number of workers have studied the absorption spectrum of the medicinal oil, and Schlutz and his colleagues [1925, 1926] and Heilbron, Kamm a...
