ABSTRACT
The quantitative content of HIF-1α- and HIF-2α-immunopositive brain neurons in Wistar rats was studied 1, 15, and 30 days after modeling of myocardial infarction. In rats of the control group, the immunohistochemical markers HIF-1α and HIF-2α in the prefrontal cortex of the brain were determined in few pale-colored neurons and capillaries. One day after myocardial infarction simulation, the number of HIF-1α+ neurons increased, and on day 15 it reached the maximum level the concentration of immunopositive neurons and capillaries increased by 24.7 and 18.4%, respectively, in comparison with the control. After 30 days, the number of HIF-1α+ structures decreased, but remained above the control values. The number of neurons and capillaries positively stained for HIF-2α peaked only on day 30 of the postinfarction period.
