[Secretion into the circulating medium of lipids synthetized by isolated Wistar rat liver perfused with high concentrations of oleic acid and glycerol].

In previously 18-h fasting Wistar rats, the liver is isolated and perfused with [9, 10(-3)H2] oleic acid (346 mumol and [1-14C] glycerol (115 mumol). Then, in a circulating medium, the secretion of triacylglycerols -- synthetized de novo and by esterification of exogenous oleic acid -- and VLDL is inhibited. On the other hand, the secretion of phospholipids is getting away that regulatory process.
