title: MPO activity and generation of active O2 species in leukocytes from poorly controlled diabetic patients.
abstract: OBJECTIVE
  This study was undertaken to determine which part of ROI generation is reduced in the neutrophils from patients with NIDDM.
  
  
  METHODS
  Superoxide anion (O2-) production, LDCL activity in response to opsonized zymosan, and MPO activity were measured in leukocytes of poorly controlled NIDDM patients (FBG greater than 8.89 mM, HbA1 greater than 10%).
  
  
  RESULTS
  In diabetic subjects, both O2- production and LDCL activity assessed with initial slope gradient and peak value were significantly reduced. MPO activity was also decreased in diabetic subjects, and there was a significant correlation between HbA1 levels and MPO activity of diabetic subjects.
  
  
  CONCLUSIONS
  This study demonstrated that every step in leukocyte ROI generation should be reduced in the leukocytes from poorly controlled diabetic patients.
