Fig. 2.
The effect of acute restraint stress on inducible nitric oxide synthase (Nos2) mRNA expression in the medial prefrontal cortex (mPFC) of control and stressed rats (n=5–6 per group). The relative expression was determined in isolated mPFC collected from rats exposed to 0 (control), 60, 120, and 240 min of restraint stress. Data are expressed as mean±SEM, ⁎⁎p<0.01.
