inosine-diphosphate and Necrosis

Experiment carried out on laboratory animals (rats) were aimed at comparative evaluation of the effect of several neuroprotective drugs under the conditions of model brain ischemia-reperfusion. The experimental methods included staining of brain tissue sections by hematoxiline-eosine, Nissl staining, and expression of NOS1, NOS3, TRAIL by imunnohistological means. The intensity of damage in various parts of brain and the nature of apoptosis without neuroprotection and with popular neuroprotectors (cytoflavin, actovegin, mexidol) and a test drug at the stage ofpreclinical trial (AKF-90-7) were evaluated. Characteristic cytotoxic (coagulative pycnomorphic and colliquative necrosis of neurons) and vascular (hemostasia, erythropedesis) changes were revealed. The neuroprotective effectof drugs decreases in the following order: AKF-90-7 > cytoflavin > actovegin > mexidol.
