Figure 6

Effects of ferulic acid (FA) on the neuronal nitric oxide synthase (nNOS)-positive expression in hippocampal CA3 region of offspring rats exposed to prenatal stress. (A) nNOS expression was examined by immunohistochemistry (magnification 400×, Scale bar = 50 μm), and (B) Bar graph showing semi-quantitative analysis of nNOS via quantified integrated optical density (IOD). Values represent means ± SEM (n = 3). * p < 0.05 and ** p < 0.01 compared with PS group, ## p < 0.01 compared with Control group. FA-L: FA at low 12.5 mg/kg/day, FA-M: FA at medium 25 mg/kg/day, FA-H: FA at high 50 mg/kg/day; Flx: fluoxetine.
