effect of feeding polyunsaturated fatty acids with a low vitamin e diet on blood levels of tocopherol in men performing hard physical labor.a diet made low in vitamin e by elimination of foods considered good sources of the vitamin was fed for 13 months to two groups of men engaged in strenuous labor. with a daily average dietary intake of about 9.4 mg of total tocopherols, a progressive decline in blood levels of tocopherol from 1.42 to 0.81 mg/100 ml was observed in the five control subjects. the test group of 30 men received a daily supplement of tocopherol-stripped safflower oil containing 88 g of polyunsaturated fatty acids and ...19751146722
influence of dietary fat upon rats during gestation and lactation.a comparison was made between rats fed purified rations containing different fats during gestation and lactation and rats fed a commercial ration during similar periods. the purified ration containign 20% cocoa butter did not result in appreciable differences in the mothers (body weight, behavior, litter production, and brain chemistry) or in the 1-day-old neonates (brain chemistry). the purified ration containing 20% safflower oil resulted in fewer completed gestation, in poorer maternal behavi ...19751147333
hepatic acat activity in african green monkeys is highly correlated to plasma ldl cholesteryl ester enrichment and coronary artery atherosclerosis.previous studies and this study of african green monkeys show a strong positive correlation between plasma low density lipoprotein (ldl) size and the extent of coronary artery atherosclerosis (caa). increased ldl size was principally due to the accumulation of cholesteryl oleate molecules within the particle core, suggesting that many of these cholesteryl esters were of tissue origin, i.e., from the acyl-coenzyme a:cholesterol acyltransferase (acat) reaction instead of the lecithin:cholesterol a ...19921420087
specific inhibition of hepatic fatty acid synthesis exerted by dietary linoleate and linolenate in essential fatty acid adequate rats.dietary linoleate and linolenate were investigated for their ability to specifically inhibit liver and adipose tissue lipogenesis in meal-fed (access to food 900-1,200 hr), essential fatty acid (efa) adequate rats. supplementing a high carbohydrate diet containing 2.5% safflower oil with 3% palmitate 16:0, oleate 18:1, or linoleate 18:2 did not affect in vivo liver or adipose tissue fatty acid synthesis. however, 18:2 addition to the basal diet did result in a significant (p less than 0.05) decl ...1976933724
a possible essential role for dietary linolenic acid in the development of the young rat.female rats were fed semi-purified diets containing 10% safflower oil or 10% soybean oil for six weeks prior to mating and through-out pregnancy and lactation. the progeny were weaned to the diet of the dam. physical, neuromotor and reflex development was monitored in the progeny prior to weaning and learning ability of the mature progeny was assessed in a simple y-maze test. brain lipid analyses were conducted in the progeny at birth, 21 and 210 days of age. inclusion of soybean oil in the diet ...1976942747
influence of maternal dietary fat upon rat pups.mother rats were fed purified rations containing different fats during gestation and lactation and at 1 day after parturition. litter sizes were reduced to 2 male and 2 female pups. the behavior and the brain chemical composition of these selected pups were compared with similarly selected pups from dams fed a commercial ration. all offspring were fed a commercial ration after weaning. pups from dams fed 20% safflower oil were similar to controls. feeding 20% cocoa butter to dams resulted in pup ...19751147334
uric acid excretion by the chick as an indicator of dietary protein quality.the objective of this investigation was to determine whether uric acid excretion could serve as an indicator of dietary protein quality. in the first study, 15% protein diets were formulated using either whole egg protein, soybean meal, safflower meal or casein, or the latter 3 proteins supplemented with their most limiting amino acid (methionine, lysine and arginine, respectively). chicks fed diets supplemented with the limiting amino acid grew more rapidly and efficiently and excreted less uri ...1976945565
