Hyperbaric oxygen (HBO)/Ginkgo biloba extract 761 (EGB 761) reduces apoptosis (a–f: TUNEL staining). (a and b) There was no brown precipitate (apoptosis identification) in normal and sham groups. (c) The large visible brown precipitate (arrows) was detected in the AD model group. (d–f) The normal hippocampal neurons were surrounded by the sporadic visible brown precipitate (arrows) in the HBO; EGB 761 and HBO/EGB 761 groups. (g) The apoptotic index showed the significant difference among different groups: AD Model, HBO, EGB 761 and HBO/EGB 761 groups. *P < 0.01, †P < 0.05, versus AD model group. AI: Apoptotic index.
