8 Fig. 4 A, Frontal neocortex (×40) from group I showing area of hypoxic-ischemic injury. This most severely injured animal in this group would be scored as having 2+ lesion. Note several neurons with hypereosinophic cytoplasm and karyorrhectic nuclei (arrows). Blood vessel in upper right corner shows no pathologic change. B, Hippocampal pyramidal cell layers (from same animal as in A) showing no damage (×20). C, Fascia dentata (from same animal as A) showing no damage (×20). D, Fascia of hypoxic-ischemic damage between arrows. This animal had less injury to neocortex than did the other animal in this figure. No evidence of capillary damage or microemboli was present.
