Neutrophil functions. Mean (± SE) plasma levels of elastase (A) and MPO (B), and whole blood neutrophil numbers (C) 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 hyperglycemic versus euglycemic clamps.
