Effects of PVE on apoptosis of the uterus tissue by TUNEL staining. The groups are shown as follows: control (C); model (M); GLC positive control group (GLC, 0.30 g/kg); mifepristone positive control group (MF, 5.4 mg/kg); low-dose PVE (LPVE, 0.11 g/kg); medium-dose PVE (MPVE, 0.22 g/kg); high-dose PVE (HPVE, 0.44 g/kg). a: TUNEL staining merged figures, TUNEL (green) staining: the cell apoptosis assay stained in the green channel, DAPI (blue) staining: DAPI was applied as a nuclear counter-stain in the blue channel, × 400 magnification, scale bar:50 μm; b: apoptotic rate, compared with the normal group, ^#p < 0.05; compared with the model group, *p < 0.05
