title: [Concentration of interleukin-5 and granulocyte-macrophage colony stimulation factor in nasal polyps tissue and its significance].
abstract: OBJECTIVE
  To study the relationship between the concentration of interleukin-5 (IL-5) and granulocyte-macrophage colony-stimulation factor (GM-CSF) in nasal polyps and its significance.
  
  
  METHODS
  The concentration of IL-5, GM-CSF was measured by enzyme linked immunosorbent assay (ELISA) in a total of 38 cases, and the number of eosinophils were counted in the same tissues.
  
  
  RESULTS
  The statistical analysis showed that the concentrations of IL-5 and GM-CSF have significant difference (P < 0.05) between the nasal polyps and the control group. There is a positive correlation between the quality of IL-5/GM-CSF and the extent of eosinophils (r = 0.75/0.71).
  
  
  CONCLUSIONS
  This study demonstrated that there are inductive compartments, namely the microenvironment, in which immune-effector and inflammatory cell function is modulated in nasal polyps. A special discussion has been made of eosinophils and IL-5/GM-CSF in the formation of nasal polyps, and the effect of the IL-5/GM-CSF in the accumulation of eosinophils.
