Figure 5: Apoptotic induction (a-d) and index (e). Apoptosis induction (a-d) (400 × magnifications, TUNEL staining): sham group (a), PEN group (100 mg/kg) (b), NIT group (40 mg/kg) (c) and PEN (100 mg/kg) + NIT (40 mg/kg) group (d). Red nuclei refer to apoptotic cells. Apoptotic index (e): *Significant difference to the sham group (P < 0.01).*Significant difference to the NIT group (P < 0.01).Significant difference to the NIT group (P < 0.01). NIT: Nitrosamine, PEN: Pentoxifylline
