title: [mRNA expression of granulocyte-macrophage colony-stimulating factor in airway tissues of asthma guinea pigs: effect of triptolide].
abstract: OBJECTIVE
  To explore the role of granulocyte-macrophage colony-stimulating factor (GM-CSF) in eosinophil inflammation of asthma airway.
  
  
  METHODS
  Guinea pig models of asthma were established with aerosolized ovalbumin. A group of asthmatic guinea pigs were treated with injection of triptolide, density of eosinophil infiltration in airway tissues was observed under microscope and expression of GM-CSF mRNA in airway tissues was detected with dot hybridization by Dig-labeled cDNA probe.
  
  
  RESULTS
  Expression of GM-CSF mRNA in asthmatic animals were higher markedly than that in the triptolide-treated and the control groups. However, there was no statistically differences of density of eosinophils infiltration between the asthma and the triptolide-treated groups.
  
  
  CONCLUSIONS
  GM-CSF might participate in eosinophil inflammation in airway of asthmatic animals and triptolide might be of potential value in anti-inflammation for asthma.
