title: [Observation on the immune function of circulating red cells of patients with periodontal diseases].
abstract: OBJECTIVE
  To find out the relation between the causes of periodontal diseases and the immune function of red blood cells (RBC).
  
  
  METHODS
  The functional state of SOD activity, red blood cell C3b receptor rosstte (C3bR), red cell immune complex rosstte (RBCICR), RBC immune adherence enhance factor (RFER) and RBC immune adherence inhibitor factor (RFIR) of red cells from the systemic circulation of patients with periodontal diseases were determined and compared with the normal control group.
  
  
  RESULTS
  The SOD activity C3bR and RFER of red cells were lower, while RFIR and RBCICR were higher for patients with periodontal diseases comparing to the normal control.
  
  
  CONCLUSIONS
  It indicates that the compromised function of red cells may contribute to the initiation and development of periodontal diseases.
