Abstract: Bile salts have been shown to act on lipoprotein-X (LP-X) in vitro to induce a false-negative electrophoretic test. The aim of the present study was to investigate the relationship

Abstract: The effect of phospholipase A from snake venom and deoxycholic acid on lipoprotein-X (LP-X) recovered from the cathode side of a previous agar gel electrophoresis is described. Adding phospholipase A and deoxycholic acid to the removed cathodal fraction is followed by a marked migration to the anode side on a second electrophoresis procedure. This seems to confirm that phospholipase A and bile salts on LP-X particles modifying their agar gel electrophoretic migration characteristics.

Abstract: The effect of heparin on the proportion of cholesterol esters, lecithin/ lysolecithin ratio, and lecithin:cholesterol acyltransferase (LCAT) activity was studied in twelve patients with cholestasis. A good correlation was observed between a decreased LCAT activity and the proportion of cholesterol esters, and no consistent variation was noted after heparin. The lecithin/lysolecithin ratio was increased in 7 patients and became normal after heparin in 6 cases. The clearance of lipoprotein-X after heparin seems to be not related to LCAT activity. These results demonstrate that heparin does not modify the LCAT activity, and suggest that heparin induces an increase of phospholipase activity in some patients with cholestasis.
