  • The four LPL parameters (mass and activity in plasma and their increase after heparin administration) were not related to each other, except for postheparin plasma LPL mass and activity, and they showed different correlations with plasma lipoprotein lipid concentrations. (ahajournals.org)
  • The different relations of the measured LPL parameters to plasma lipoproteins and the difference in preheparin plasma LPL activity between patients and control subjects might reflect a disturbance of the LPL system in the patients. (ahajournals.org)
  • 1 2 Several studies have explored the relation between LPL activity and parameters of lipoprotein metabolism (for discussion, see References 3 and 4 3 4 ) by measuring LPL activity in plasma after heparin injection, which is assumed to reflect the LPL available at the endothelial surface, or by studies of LPL activity in tissue biopsies.
