Paraffin sections were dewaxed and hepatic cell apoptosis was detected by terminal deoxynucleotidyl transferase mediated dUTP nick-end labeling (TUNEL) assay using the TUNEL assay kit (Roche, Shanghai, China) according to the manufacturer’s protocol. Nuclei were labeled by DAPI staining (Biohao Biotech, Shanghai, China). Sections were then observed under a confocal laser microscope (Olympus, Japan). The percentage of apoptotic cells was calculated by counting TUNEL-positive cells in five randomly selected fields on each slide.
