Nissl and TUNEL staining of the perihematomal tissue 24 h after ICH. a Coronal brain slice shows oval-shaped hematomas at the right basal ganglia. b Nissl staining showing a decrease in the number of stained cells and more severe structural damage of the neurons around the hematoma in HI animals. However, the neuronal damage in HI-HBO animals was reduced. Right arrow indicates normal neuron, up arrow indicates damaged neuron in the photos. c Quantification analysis indicating TUNEL-positive cells increased in HI animals and decreased in HI-HBO animals. The percentage of TUNEL-positive cells was expressed as the number of TUNEL-stained nuclei divided by the total number of DAPI-stained nuclei. * P <0.05. Bar = 100 μm
