A novel i.v. lipid preparation (MCT:FO) containing 80% medium chain-triacylglycerols and 20% fish oil was recently developed to rapidly replenish cell membrane phospholipids with omega 3 (n-3) polyunsaturated fatty acids (PUFA). In regard of this property, we investigated the effect of a single i.v. administration of MCT:FO on the recovery of cardiac function after ischemia in control and n-3-depleted rats. Results were compared with those obtained either with a control preparation, where FO was replaced by triolein (MCT:OO), or with saline. Saline (1 ml) or lipid preparation (also 1 ml) was injected as a bolus via the left saphenous vein. After 60 min the heart was removed and perfused for 20 min in normoxic conditions according to Langendorff. Thereafter, the heart was subjected to a 20 min zero-flow normothermic ischemia, followed by 40 min reperfusion. Cardiac mechanical and metabolic functions were monitored. In control rats, the previous administration of a lipid preparation (MCT:FO or MCT:OO) versus saline improved cardiac function during aerobic reperfusion post-ischemia. N-3-depleted rats showed decreased basal cardiac function and impaired recovery following ischemia. However, the bolus injection of MCT:FO opposed the deleterious effect of long-term n-3-deficiency and, in this respect, was superior to MCT:OO over the first 20 min of reperfusion. This novel approach to rapidly correct n-3 PUFA-deficiency might be clinically relevant and offer interesting perspectives in the management of acute ischemic accidents.
