title: [Effects of the level of polyunsaturated fatty acids of the diet on the functioning and depletion of energy substrates in the rat heart during perfusion by left atrial route].
abstract: The effects of semi-liquid diets containing 6.6% in weight of refined sunflower seed oil (SSO) or hydrogenated coconut oil (HCO) on cardiac endogenous substrates and functional parameters of rats hearts were compared to a standard laboratory chow during seven days. No difference appeared for cardiac glycogen and lipid constituents. Cardiac performance, measured through left atrial perfusion was enhanced by SSO diet and HCO one altered it. A significative phospholipid depletion appeared during the 45 minutes perfusion only in the HCO group.
