Figure 10From: Single-prolonged stress induces apoptosis in dorsal raphe nucleus in the rat model of posttraumatic stress disorder Mean optical densities of TMP is shown at different time points in dorsal raphe nucleus dorsal raphe nucleus (mean ± SEM). The expression of TMP peaked at SPS 7d, and then decreased gradually. P < 0.001 SPS vs. control group. Tukey’s test: ▲P < 0.05 SPS 1d vs. control group. ●P < 0.05 SPS 7d vs. SPS 1d. ■P < 0.05 SPS 14d vs. SPS 7d.Back to article page
