(A) Normal cellular morphology was present in the sham group. Compared with the (B) model group, a gradual improvement in condensed nuclei (arrows) was detected in the hippocampal CA1 region in the (C) Nim group, (D) GAS 15 mg/kg group, (E) GAS 30 mg/kg group and (F) GAS 60 mg/kg group. Arrows indicate impaired neurons. GAS, gastrodin; HE, hematoxylin and eosin; Nim, nimodipine.
