[The anti-hyperlipemic and anti-atherogenic effect of "essential" phospholipids: a pharmacologic trial].

To prove antilipemic and antiatherogenic effectiveness several animal species were given "essential" phospholipids (EPL) during different experimental procedures. The following actions were studied: 1. Effect of EPL-substance after prophylactic and therapeutic oral administration (dosage: 50, 150, 450 mg/kg bodyweight daily) in rats with acute and subacute hypelipemia induced by triton. 2. Effect of EPL-substance after prophylactic and therapeutic oral administration (dosage: 50, 150, 450, 1800 mg/kg bodyweight daily) in rats with dietetic hypercholesterolemia. 3. Effect of EPL-substance after daily oral administration (dosage: 50, 150, 450 mg/kg bodyweight) on the development of coronary and aortic atherosclerosis and various biochemical parameters in cholesterol-fed cockerels. 4. Effect of EPL-substance after dialy oral administration (dosage: 50, 150, 450 mg/kg bodyweight) on subacute triton-hyperlipemia in mini pigs. Triton-administration causes a greater or smaller increase in all parameters of the lipid metabolism measured. EPL treatment decreases these parameters during therapeutic and prophylactic administration in some cases even reaching normal values. The effect was clearly dose-dependent. EPL inhibit the increase in total lipids in dietetic hypercholesterolemia during therapeutic as well as during prophylactic administration. The effect was clearly dose-dependent in all doses, being statistically significant at the highest dosage level. In cockerels EPL were effective at all dose levels in counteracting the development of coronary atherosclerosis while the effect in atherosclerosis of aorta was less distinct. Except for non-esterified fatty acids, EPL reduced all biochemical parameters measured.
