Fully refined rapeseed oils containing different amounts of erucic acid (1.6%, 4.3% and 22.3%) were fed, at 20% by weight of diet, to weanling male and female Sprague-Dawley rats for periods up to 112 days. Transient myocardial lipidosis characterized by accumulation of fat droplets in myocardial
Detailed morphometric studies performed in heart tissue from Swiss mice and Wistar rats show that, in comparison with other edible oils, long-term feeding of the new rapeseed oils, poor in erucic acid, do not significantly affect the incidence of myocardial background lesions, in contrast to
Sclerosis of the liver accompanied by hydropericardium of long standing was observed in turkeys fed rapeseed products for 16 weeks. Histologically, extensive increases of fibrous tissue composed predominantly of reticular fibres and centrilobular degeneration of parenchymal cells were the main
Livers of turkeys fed low and high glucosinolate rapeseed meal diets for 16 weeks were examined ultrastructurally. Hepatocytes from birds fed on Tower rapeseed meal (0.15 mg of glucosinolate per g) showed a mild accumulation of lipid droplets and an apparent increase in lysosomes and microbodies.
Livers of laying hens of Hy-Line No 934E on low erucic acid rapeseed meals and rapeseed oil were studied. Gross lesions in the livers of hens on experimental diets were moderate to severe fatty degeneration, focal necrosis and moderate to severe haemorrhage. Histological examination revealed
Haemorrhagic livers were observed in male white rock chicks of one to four weeks old, that were fed diets supplemented with 50 per cent rapeseed meal and 50 per cent rapeseed full-fat seeds. The haemorrhagic lesions were comparable to those of the laying hens except for the absence of fatty
Rapeseed meal, the residue after oil extraction, is an animal feed of great commercial interest. Some genetic strains of rapeseed yield a meal which when fed in high concentration produces hemorrhagic lesions in the liver of chickens. These lesions are reduced in incidence by the simultaneous
The fatty acid patterns of oils, blood plasma and erythrocyte lipids from 28 children in the Shaanxi province of the People's Republic of China were determined by capillary gas liquid chromatography. The main source of fat in this region is rapeseed oil. The analysis of locally available rapeseed
The ultrastructure of the livers of four-week-old White Rock broiler chickens fed diets containing 50% rapeseed meal was examined. Multifocal hepatocytic necrosis was observed in most of the birds fed the experimental diets. Early degenerative changes were swelling of mitochondria and vacuolations
Three feeding groups were used: the control (SOY) was fed diets without rapeseed products, and the two experimental groups were fed with either 10% rapeseed meal (RSM) or with 12% OO rape seeds (PFRS). Half of the boars from each group were slaughtered after 1 or 2 years. In RSM and PFRS boars
In a recent review on the role of fats in human nutrition Vergroesen and Gottenbos (1975) emphasize, that the presence of erucic acid isomers in hydrogenated marine oils (HMO) may constitute a toxicological problem as serious as erucic acid in rapeseed oil (RSO). On the contrary Christophersen et
OBJECTIVE
The sterol profile of rapeseed oil differs from that of tall oil with higher contents of campesterol and brassicasterol. We previously found that margarines providing 2 g/day of sterols from rapeseed or tall oil resulted in similar reductions in LDL cholesterol of 8-9%. The aim of the

The aim of the study was to assess the influence of α-lipoic acid (ALA) on the morphology of the aorta and liver of rabbits fed high fat diet with addition of oxidised (ORO) and non-oxidised rapeseed oil (N-ORO).

The study was conducted on male chinchilla rabbits divided into
Male Wistar rats were fed semipurifed diets containing 20% fat for 25 weeks. Ten different oils or oil blends were employed, including rapessed oils, simulated rapeseed-type oils, and modified rapeseed-type oils. Safflower, soybean, and hydrogenated coconut oils served as control oils.
The cardiopathogenicity of oils from new, low erucic acid (EA) rapeseed, Brassica napus, cv Tower (0.88 per cent EA) and Brassica napus, cv 1788 (3.6 per cent EA) were tested on rats following 18 weeks of feeding. Oil from Brassica napus, cv Target, with 38.9 per cent EA served as a positive control
