Histological image of hippocampus in animals in group IPDA (enlargement 400x). In the lumen of capillary vessels, there are numerous erythrocytes visible in rouleau formation (1), which may indicate the presence of venostasis; a small concentration of macrophages and microglia cells is observed in perivascular zone (2); in some ganglion cells, degradation states are found in the form of cytoplasmic vacuolation (3).
