Effect of scutellaria baicalensis stem-leaf total flavonoid (SSTF) on apoptosis of the hippocampal CA1 region in rats with cerebral ischemia-reperfusion injury (TUNEL staining, light microscopy, scale bar: 50 μm).

(A) In the control group, apoptotic cells were rarely seen. (B) In the sham group, few apoptotic cells were observed. (C) In the model group, the number of apoptotic cells was increased. (D–F) In the SSTF low-, medium-, and high-dose groups, the number of apoptotic cells was significantly reduced compared with the model group, and only a few apoptotic cells were visible in the SSTF high-dose group. Arrows indicate apoptotic cells.
