Effect of 14-day (PD 49–62) treatment with T-817MA, HPD, or RPD on the density of PV-positive GABAergic interneuron cells (cells/mm²) in the hippocampus in rats that did or did not receive neonatal treatment with MK-801. DW group (n = 12), HPD group (n = 10), RPD group (n = 10), and T-817MA group (n = 11) treated neonatally with saline are shown in the left side. DW group (n = 9), HPD group (n = 11), RPD group (n = 11), and T-817MA group (n = 9) treated neonatally with MK-801 are shown in the right side. Data of saline group (open bars), HPD group (dark bars), RPD group (shaded bars), and T-817MA group (closed bars) are shown. Values are expressed as means ± SEM. ^#; P < 0.05 as compared with saline-DW group. *; P < 0.05 as compared with MK801-DW group.
