Figure 2: Peritoneal concentrations of PAI-1 (ng/ml) in controls (NaCl) and experimental group (PL/PG) before (0h) and after surgery (2h-7d) No significant difference in concentrations were seen between the PL/PG group and controls as a total. A significant difference in PAI-1 concentration between PL/PG and controls were seen at 4h (p=0.019) and 7d (0.026). Graphs show PAI-1 concentration ┬▒SE.
