Figure 3 Photomicrographs of hippocampus sections stained by hematoxylin–eosin stain. (a) Control group showing pyramidal layer of normal neuronal cells with prominent nuclei (N). (b) Dexamethasone group showing decrease of thickness and necrosis of pyramidal layer and apoptotic (arrowhead) with pyknotic nucleoli (P). (c and d) Dexamethasone and Hypericum perforatum (100 and 200 mg/kg, respectively) group showing thick pyramidal layer of near-normal appearance, moderate apoptotic (arrowhead), and pyknotic nucleoli (P) (hematoxylin–eosin stain, ×400).
