Fibrinolysis markers. Mean (± SE) plasma levels of PA activity (A), PAPc (B), t-PA antigen (C), PAI-1 antigen (D), and PAI-1 activity (E) after LPS administration (4 ng/kg intravenously, T = 0 hours), during one of the following conditions: an L_insuE_gluc clamp (□), an L_insuH_gluc clamp (○), an H_insuE_gluc clamp (■), and an H_insuH_gluc clamp (●). *P < .05, **P < .01, and ***P < .001 hyperinsulinemic versus lower insulinemic clamps; †P < .05 hyperglycemic versus euglycemic clamps.
