title: [The number and affinity of fibrinogen receptors in blood platelets of patients with ischemic stroke].
abstract: Parameters of fibrinogen binding with blood platelets (number of receptors and their affinity) have been studied in patients with ischemic stroke. Due to the increased platelet ability to aggregate in the ischemic diseases such studies seem helpful. The studies involved 13 patients with ischemic stroke. Blood platelets collected from younger patients (under 50 years) possessed significantly higher number of receptors binding fibrinogen than blood platelets of healthy individuals (p less than 0.02). These receptors significantly more strongly bound ligand than those in the control group (p less than 0.05), and in the group of older patients with stroke (less than 0.05). Fibrinogen binding to blood platelets in patients over 50 years of age did not differ significantly from that in the control group. These results may indicate, that the increased platelet aggregation might be a significant pathogenic factor of the stroke in younger patients.
