Figure 6From: Single-prolonged stress induces apoptosis in dorsal raphe nucleus in the rat model of posttraumatic stress disorder Double-labeled flow cytometry analyzed apoptosis rate in dorsal raphe nucleus at different time points (mean ± SEM). The apoptosis rate peaked at SPS 7d. 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
