Summary
A method for assay of lipolytic activity in platelet-poor plasma (PPP), platelet-rich
plasma (PRP) and washed human platelets is presented. The lipolytic activity in PRP
was about twice the activity in PPP. A significant correlation between lipolysis in
platelets and platelet number was established. Molar sodium chloride strongly inhibited
lipolytic activity in platelets and a washing procedure did not significantly change
the lipolysis. The results indicate that a lipoprotein lipase is bound to human platelets
and may play a role in metabolism of triglyceride in platelets.
