Abstract

Fat accumulation occurred in the myocardium of young rats fed docosenoic acid provided by liquid or partially hydrogen-ated rapeseed oil or partially hydrogenated herring oil. The composition of the cardiac fatty acids and the histopathology in rats receiving oil as 40% of calories were studied after 3, 7, 14 and 28 days. In those fed liquid rapeseed oil, a peak accumulation was reached at 7 days and thereafter decreased, and the concentration of docosenoic acid was higher than in those fed the hydrogenated oils.

A zero-effect level of abnormal fat deposition from liquid rapeseed oil was found to be 5% by weight of the diet or 10% of calories. Further increases in the level of dietary rapeseed oil enhanced the cardiac fat droplets and the accumulation of dietary fatty acids, particularly docosenoic acid.

Canbra oil had no effect on lipid accumulation in the heart.

喂食含长链脂肪酸油的大鼠心脏脂质变化
用液体或部分氢化菜籽油或部分氢化鲱鱼油提供二十二烯酸后,幼鼠心肌发生脂肪堆积。分别在3、7、14、28 d后,观察油占40%热量大鼠心脏脂肪酸组成及组织病理学变化。饲喂液态菜籽油的各组在第7天达到积累高峰,随后逐渐减少,二十二酚酸浓度高于饲喂氢化油的各组。研究发现,液态菜籽油中异常脂肪沉积的零效应水平为饮食重量的5%或卡路里的10%。饮食中菜籽油水平的进一步增加增加了心脏脂肪滴和饮食中脂肪酸,特别是二十二酚酸的积累。蓖麻油对心脏的脂质积累没有影响。
