Changes in the hemostasis system and free-radical lipid oxidation in the acute stage of ischemic stroke in patients on neuroprotection treatment


We examined 163 patients with primary ischemic stroke admitted within the first 12 h after stroke onset. Neurological status on the Orgogozo scale and blood test results (lipid spectrum, level of free-radical lipid oxidation measured with chemiluminescent method, hemostasis system parameters) were estimated at admission and on the 21th day of stroke. Patients were stratified into 3 groups: group 1 (n=59) received traditional treatment and mexidol during the first 10 days in dose 500,0 mg intravenously and cerebrolysate in dose 1,0 ml intramuscular; group 2 (n=60) received cerebrolysate in dose 1,0 ml intramuscular during 10 days in addition to traditional treatment; group 3 (n=44) received only traditional treatment. At baseline, patients with ischemic stroke demonstrated the increase in blood plasma atherogenicity (p<0,05), intensity of free-radical lipid oxidation and thrombogenic potential of blood that were correlated with disease severity. Administration of neuroprotective drugs mexidol and cerebrolysate in addition to complex treatment of stroke improved the lipid spectrum, reduced the intensity of free-radical lipid oxidation, stabilized hemostasis parameters. The increase in survival rate and more rapid reversal of neurological deficit in patients of group 1 were identified to the 21th day.
