EFFECTS OF DIFFERENT GLYCOSAMINOGLYCANS ON MYOSIN ATPASE ACTIVITY IN PLATELETS

Heparin is well known for increasing microvascular bleeding and capillary permeability [1]. Heparin also affects many functional characteristics of platelets, such as agonist-induced aggregation, piatele! adhesion [2], release of serotonin, thromboglobulin and PF4 [3]. Furthermore, heparin induces thrombocytopenia [4], prolongs thè bleeding lime in patients and has antithrombotic activity [5].
