To investigate the effects of two levels of dietary corn oil on tumorigenesis, semipurified diets containing 5% or 10% corn oil were fed during the promotion stage of a mouse skin carcinogenesis model. Sencar mice were initiated with 10 nmol dimethylbenz[a]anthracene (DMBA) and promoted with either
We investigated the effects of type of dietary fat and phenobarbital on gamma-glutamyl transpeptidase-positive foci development. Four groups of six female Sprague-Dawley rats were initiated with diethylnitrosamine (15 mg/kg) at 24 hours of age. After weaning, they were fed nutritionally complete
A study was carried out in domestic felines to determine whether corn oil-based maternal diets are an adequate source of essential fatty acids to support normal accumulation of long-chain polyunsaturated fatty acids in the brains and retinas of offspring and whether these diets have any subsequent
The effects of 1% arachidonic acid ethyl ester (AA) administration on the liver prostanoid metabolites and on serum and liver lipids in 3 g/kg ethanol-administered rats fed 10% lard or corn oil were studied. The rats were divided into 6 groups: lard-sucrose (Lard-Suc); lard-ethanol without AA
Several recent reports have shown that diets in which the only source of fat was fish oil can modify the course of diseases with an inflammatory or immune component. In these experiments we examined the effect of a fish oil diet on experimental amyloidosis in mice. In most azocasein-treated mice,
Polyunsaturated fatty acids (PUFAs), such as arachidonic acid (ARA) and docosahexaenoic acid (DHA) are natural constituents found in human milk, fish oil or egg yolk. Until recently, infant formulas, though providing the essential fatty acid precursors for these PUFAs, did not contain preformed ARA
Feeding natural fats varying in contents of palmitate (16:0), stearate (18:0), oleate (18:1), and linoleate (18:2) to rabbits resulted in modulation of platelet phospholipid fatty acyl composition. Rabbits were fed high fat semipurified diets containing 2% corn oil (CO) + 18% CO, cocoa butter (CB)
Liver slices, from mice fasted for one day and then refed for three days either a 15% corn oil diet or a 15% corn oil diet containing eicosa-5,8,11,14-tetraynoic acid (TYA), were incubated with [1-14C] acetate or [3H] H2O to determine lipogenic capacity. Dietary TYA produced a twofold stimulation in
Young male rats of the Long-Evans strain were fed 10% lard or corn oil diets for 4 weeks. Analysis of plasma cholesterol showed a decrease of 22%; a decrease of the same order of magnitude as also observed in the lipoproteins, particularly in the VLDL fraction, with the unsaturated diet. Plasma
Groups of rats were fed diets containing 10% of either corn oil, partially hydrogenated soybean oil, or a mixture of the two. The partially hydrogenated oil contained a high level of trans-octadecenoate and a low level of linoleate, and all diets were adjusted to contain similar levels of
Day-old male broiler chickens were fed semipurified diets containing 5% lipid from one of four different lipid sources: corn oil (CO), partially hydrogenated soybean oil (HSBO), a spent restaurant grease (SRG) and a purified mixture of triolein, tripalmitin and tristearin (OPS). Diets CO and HSBO
The effect of dietary lipid on gamma-glutamyl transferase-positive (GGT-positive) foci was investigated. Female Sprague-Dawley rats were dosed with diethylnitrosamine (15 mg/kg) at 24 h of age. After weaning, they were fed nutritionally complete semipurified diets for 3 months. Rats fed 15% corn oil
We have previously reported that compared to a corn oil diet a fish oil diet (5% by weight) fed to B10R.III mice before the induction of collagen induced arthritis markedly reduced disease severity. In this study we determine whether a fish oil diet could reduce the severity of collagen induced
Weanling male spontaneously hypertensive rats were fed semipurified diets containing either corn or fish oil for 8 weeks. Rats fed on fish oil diet had significantly lower plasma triglyceride, total cholesterol and HDL-cholesterol levels than rats fed on corn oil diet (P < 0.05). Moreover, rats fed
