Figure 7. The numbers of PSD-95 and synaptophysin positive cells in PFC are modified by ketamine exposure.
The rat with location of the medial prefrontal cortex (PrL, a). Areas of prefrontal cortex as indicated in (b) and laminae II-III as indicated in (e–h) were selected for analysis. Paraffin coronal sections from P30 PFC were stained with anti-PSD-95 and anti-synatophysin (SY-38) antibodies. Fluorescent immunohistochemistry for PSD-95 (green) and SY-38 (green), and DAPI (blue). The signal was estimated by quantifying the density of immnofluorescence using Image J. The ketamine group showed a significant increase of PSD-95 immunoreactivity (c) and a significant decrease of synaptophysin (d) at P30 compared to the control. *p < 0.05; n = 6 in each group.
