title: [Expression of nucleolar organizer regions associated proteins of T lymphocytes in the patients with oral and maxillofacial tumors].
abstract: OBJECTIVE
  To study the Ag-NORs expressive character of T lymphocyte in patients with oral and maxillofacial tumor and evaluate its diagnostic value for the patients.
  
  
  METHODS
  Nucleolar organizer regions(NORs) of T lymphocyte from 86 normal adults, 102 patients with oral and maxillofacial benign tumors and 87 patients with oral and maxillofacial malignant tumors were analyzed through KL imaging system.
  
  
  RESULTS
  There was significant difference among normal adults, benign and malignant patients (P < 0.01). Their average I.S% values were 7.87 +/- 0.12, 5.72 +/- 0.14, 4.19 +/- 0.13, respectively.
  
  
  CONCLUSIONS
  The expression of Ag-NORs of T lymphocyte has definite relation with oral and maxillofacial tumors; detection of Ag-NORs might play valuable in diagnosis of oral and maxillofacial tumors.
