SUMMARY. Changes of thrombocyte morphological and functional status were investigated in rabbits (2,5–3 kg weight) by the emotional stress model that was reproduced through stimulation with irregular low-level electric current. Thrombocytes were purified from the venous blood with sequential centrifugation. Obtained material was investigated with electron microscope using luminous coloring agent acridine orange and syliconized glass. Glycosaminoglycans and Ca2+ noncompensated negative electric charge, the activity of ATP, alkaline phosphatase, adenylate cyclase and phosphodiesterase of cyclical nucleotides, monoamine oxidase were cytochemicaly revealed. Consequently morphological and functional equivalents of chronic stress destabilization effect on blood platelets were determined. Likewise membranotropic and receptor mediated mechanisms of this effect realization were analyzed.
Keywords: stress, platelets, morpho-functional changes
