Changes in PSD95 expression after HI injury (× 200, × 400). A–E PSD95 staining of the brain sections and mean integrated optical density changes in 6–12 h, 12–24 h, 24–48 h and 48–72 h groups after HI, with respective controls. Green fluorescence represents PSD95. F The PSD95 fluorescence intensity increased and then decreased after HI, increased at 6–12 h, lasted until 24–48 h and significantly decreased at 48–72 h. (**P < 0.01, *P < 0.05, data are expressed as mean ± standard deviation)
