Fig. 1.

Frontal lobes, magnification × 200. H&E and anti-BYSL staining in the 3rd neuronal layer of the neocortex. GFAP marks white matter. a – control group (sudden death), slightly pronounced brain edema; b - control group, normal view of astroglia; c – control group (sudden death), white matter, minimal BYSL expression in neuron cytoplasm; d – HI group - brain edema, ischemic neurons and perineuronal satellitosis; e – HI group, astroglia proliferation and clasmatodendrosis; f – HI group, white matter, statistically significant (comparing to control group) increased BYSL expression in cytoplasm of ischemic neurons; g – HIR group with brain edema, ischemic neurons and severe perineuronal satellitosis; h – HIR group, slightly more pronounced astroglia proliferation and clasmatodendrosis; i – HIR group with no BYSL expression. Inserts b, e, h shows astrocytes in higher magnification
