title: [Research on the regular pattern of Ag-NOR changes in patients with cancer].
abstract: OBJECTIVE
  To correlate the relationship between rDNA transcriptional activity of CD4+ helper T cells and immunity in patients with cancer through silver stainability of nucleolus organizing regions (Ag-NORs).
  
  
  METHODS
  The Th(CD4+) rDNA transcriptional activity was compared among patients with cancer, infectious diseases, non-cancerous non-infectious diseases through image analysis.
  
  
  RESULTS
  Th(CD4+) rDNA transcriptional activity was decreased extremely in patients with cancer, but increased in patients with inflammation compared with normal controls.
  
  
  CONCLUSIONS
  The analysis of Th(CD4+) rDNA transcriptional activity may serve as a new tumor marker for tumor diagnosis and differential diagnosis. Therefore, it may provide an innovative and reliable method for clinical cancer diagnosis.
