[Role thrombocytes in etiopathogenesis of ischemic stroke].
This paper presents the most essential problems concerning the role of platelets in the genesis of ischaemic brain disease and their role in spreading of ischaemic focus. The role of platelets in atherogenesis and development of vascular abnormalities in arterial hypertension and diabetes mellitus was considered, and attention was paid to conditions concerned with the pathogenesis of ischaemic stroke such as presence of antiphospholipid antibodies and presence of large volume platelets, in which platelet activation plays essential role. Then it was shown that platelet hyperactivation occurs in acute phase of ischaemic stroke and mechanisms of destructive action of activated platelets on recent ischaemic focus in brain such as secretion of neurotoxins and blocking of microcirculation by platelet aggregates were discussed.
