title: [Expression of connective tissue growth factor gene in the hypertrophic scar and keloid tissue].
abstract: OBJECTIVE
  To explore the effect of connective tissue growth factor on the pathogenesis of hypertrophic scar and keloid tissue.
  
  
  METHODS
  The content of hydroxyproline was determined and the expression of connective tissue growth factor gene was detected by the reverse transcription-polymerase chain reaction and image analysis technique in 5 normal skins, 15 hypertrophic scars and 7 keloid tissues.
  
  
  RESULTS
  The contents of hydroxyproline in the hypertrophic scar (84.10 +/- 1.76) and keloid tissue (92.38 +/- 2.04) were significantly higher than that of normal skin tissue (26.52 +/- 4.10) (P < 0.01). The index of connective tissue growth factor mRNA in the hypertrophic scar (0.78 +/- 0.63) and keloid tissue (0.84 +/- 0.04) were higher than that of normal skin tissue (0.09 +/- 0.25) (P < 0.01).
  
  
  CONCLUSIONS
  Connective tissue growth factor may play an important role in promoting the fibrotic process of hypertrophic scar and keloid tissue.
