TUNEL apoptosis staining and Bcl-2 and Bax protein levels in the small intestine epithelial following severe shock. (a) TUNEL staining (original magnification ×400). (b) Statistical analysis of TUNEL results (–10). (c) Representative western blotting for apoptosis-related protein (Bcl-2 and Bax). (d-e) Densitometry analysis of Bcl-2 and Bax ( per group). , compared with the control group; , compared with the vehicle group; , compared with the PD group. DAPI, 4′,6-diamidino-2-phenylindole; TUNEL, terminal deoxynucleotidyl transferase dUTP nick end labeling; HPF, high power field; Bcl-2, B-cell lymphoma-2; Bax, Bcl-2-associated X protein; PD, polydatin.
