Dose-dependent inhibition of peritoneal leukocyte adhesion to fibrinogen and fibronectin. The inhibition of peritoneal leukocyte adhesion (OD/106 cells) to fibrinogen (black circles) and fibronectin (open circles) by 10-10M, 10-11M and 10-12M feG is shown for cells obtained from unsensitized rats that were either untreated (A) or pretreated with 100 μg/kg feG intraperitoneally 18 h before collecting the cells (B). Mean ± SEM; p < 0.05. * less than no feG in vitro (0). N ≥ 4.
