Figure 7: Concentrations of active TGF-β1 (pg/mg) from biopsies of adhesions at day 7 (after surgery), and at day 14 (after adhesiolysis) in group A, receiving NaCl before and after adhesiolysis, group B receiving PL/PG before and after adhesiolysis, and group C receiving NaCl before and PL/PG after adhesiolysis. Graphs show concentrations (mean) ± SE.
