Figure 3: Peritoneal concentrations of IL-6 (Pg/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 small significant difference in IL-6 concentration between PL/PG and controls were seen at 7d (p=0.041). Graphs show IL-6 concentration ±SE.
