[Circulating immune complexes in ischemic and hemorrhagic strokes].

The study aimed at determination of circulating immune complexes (CIC) levels in a serum of patients with ischemic and hemorrhagic strokes, isolation of the complexes and their antigen composition identification. Spectrophotometric assay, polyethylene glycol precipitation and SDS PAG electrophoresis were used. Comparing to controls, significantly elevated levels of both small and big CIC were detected in the serum of the patients with ischemic stroke, while in the patients with hemorrhage stroke only the level of small CIC was elevated.

[Change in indicators of peroxide resistance in erythrocytes and lipid metabolism indicators in blood plasma during development of ischemic insult].

The authors have displayed that ischemic insults are accompanied by the significant intensification of free radical peroxidation processes both in erytrocyte membranes and in blood plasma. The changes mentioned are characterized by the simultaneous decrease of erytrocites resistance to peroxide hemolysis, as well as by the parallel lowering of alpha-tocopherol concentration in blood plasma.
