Hepatocyte apoptosis was evaluated via TUNEL staining assay.

<p>Typical images were selected from each experimental group (original magnification: 100×). (<b>A</b>) Vehicle control, (<b>B</b>) clivorine (210 mg/kg), (<b>C</b>) clivorine (210 mg/kg) + quercetin (40 mg/kg), (<b>D</b>) clivorine (210 mg/kg) + quercetin (60 mg/kg), (<b>E</b>) clivorine (210 mg/kg) + quercetin (90 mg/kg), and (<b>F</b>) Quercetin (90 mg/kg). Arrows indicate apoptotic hepatocytes. (<b>G</b>) The apoptotic hepatocytes were counted manually in at least three random fields every section. Data are expressed as means ± SEM (n = 6). <i>*P<0.05</i> compared with the control; <i>^#P<0.05</i> compared with clivorine.
