DLG4 and bronchopulmonary dysplasia: It was worth noting that the mean fluorescence intensity of PSD95 of BPD + NS group in the DG area at P70 was inferior than the CON group and ROS treatment could enhance it (Figure 6C,D; F(2,25) = 11.64, p = 0.0003 for treatment; p = 0.0005 for BPD + NS vs. CON and p = 0.0008 for BPD + NS vs. BPD + ROS in Figure 6D).
