Response of plasma lipid fractions to the administration of exogenous phospholipids.

Plasma lipidic fractions (total lipids, free and total cholesterol, triglycerides, total phospholipids and low density lipoproteins) of 16 hyperlipemic subjects have been followed up over a 4-week period. Intravenous injection of exogenous phospholipids prepared from pig heart resulted in a significant decrease of all the examined lipidic fractions. The possible mechanims of exogenous phospholipids action is discussed.
