title: [Blood cell aggregation and oxidative stress in pathogenesis of ischemic stroke].
abstract: Rheologic properties of blood cells and a state of oxidative-reductive processes and blood systems have been studied in 75 patients in acute period of ischemic stroke. The signs of oxidative stress development and simultaneous augmentation of blood cells aggregation were found. Shifts of redox-equilibrium in thiol-disulfide and ascorbate oxidative-reductive blood systems and cells aggregation dependence on their state were detected. An interrelation of oxidative processes and blood cells aggregation with clinical course severity and outcome was revealed. The authors discuss possible mechanisms for blood cells aggregation in oxidative stress. Including of antioxidants in the pathogenetic therapy and their earlier usage reduce essentially the intensity of oxidative stress and blood cells aggregation and promote neurological symptoms regress. The results obtained allow considering antioxidant treatment as a pathogenic modality for prevention and treatment of ischemic stroke. Clinico-laboratory correlations suggest a pathogenic role of oxidative stress in ischemic stroke as a factor augmenting aggregation processes and promoting intravascular thrombogenesis.
