Blood serum structures integrated assessment of pathophysiological changes in experimental cerebral ischemia

Abstract

The purpose. To reveal solid-phase structures of blood serum during and after experimental cerebral ischemia. Methods. Integrated estimation pathophysiological changes at brain ischemia received on solid-phase structures of blood serum (BS) at 27 rats-male Vistar in weight of 300‒390 g. Reversible brain ischemia of moderate severity was reproduced imposing surgical clips on both common carotids for 15 minutes then clips removed and provided bloodstream restoration on carotids. Blood took away in Eppendorf´s test tube in volume on 1 ml before imposing clips, directly ahead of their removal and in 30 minutes after bloodstream restoration. By the Method cuneiform dehydration received BS facia (dry a film) which structures analyzed by means of stereomicroscope MZ12 firm "Leica". Results of researches fixed on structural parameters BS before imposing clips, after removal clips and in 30 minutes after bloodstream restoration. Results.Before ischemia the integrated picture facias BS rats had the harmonious system organisation: the radial or partially-radial arrangement of the cracks, accurately generated konkrecias that testified to normal physiological condition of experimental animals. During the period occlusions carotids there were markers of a ischemia, activation of a capillary blood-groove, inflammatory reaction and stress. Partially these signs remained at reperfusion. Conclusion. The conducted researches of structures BS on experimental animals have allowed to reveal marker structures BS similar revealed at inspection of people with an ischemia of a brain.
