Figure 4

Protein expression, acetylation, and activity of SOD2 in small intestinal tissue following severe hemorrhagic shock. (a) Representative western blotting bands of SOD2 protein and relative gray values ( per group). (b) Acetylated SOD2 (Ace-SOD2) level determination ( per group). (c) SOD2 activity of small intestinal homogenate ( per group). , compared with the control group; , compared with the vehicle group; , compared with the PD group. SOD2, superoxide dismutase 2; Ace-SOD2, acetylated superoxide dismutase 2; GAPDH, glyceraldehyde 3-phosphate dehydrogenase; PD, polydatin.
