Figure 1From: Single-prolonged stress induces apoptosis in dorsal raphe nucleus in the rat model of posttraumatic stress disorder The distribution of Cyt-C in mitochondria were found in dorsal raphe nucleus by TEM in each group (Figure 1A-D), Positive expression of Cyt-C, high electron-dense black granule(↑) in exterior and interior membrane of mitochondria. A: Mitochondria is intact, positive granule of Cyt-C were plentiful in control group; B: Part of Mitochondrial cristae fracture and membrane disruption,positive granule of Cyt-C were partly decreased in SPS1d group; C: Part of Mitochondrial vacuolization,positive granule of Cyt-C were obvious decreased in SPS 7d group. D: Part of Mitochondrial cristae fracture and membrane disruption,positive granule of Cyt-C were partly decreased in SPS14d group. All images are taken with identical magnification (Scale bar =500 nm).Back to article page
