Changes in synaptophysin expression after HI injury (× 200, × 400). A–F. Syph 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 syph. (**P < 0.01, *P < 0.05, data are expressed as mean ± standard deviation)
