title: [Relationship between angiogenesis and expression of HO-1 of scar].
abstract: OBJECTIVE
  To investigate the relationshion between the angiogenesis of different kinds of scar and expression of HO-1.
  
  
  METHODS
  The expression of heme oxygenase-1 and vessel counted by CD34 of biopsies from different kinds of scars such as hypertrophic scar, keloid, surgical scar and normal skin of 24 cases was valued by immunochemical method, and the relationship was compared between them.
  
  
  RESULTS
  The vessel count of hypertrophic scar, keloid was significantly abundant compared with surgical scar or normal skin (P < 0.01). While the expression of HO-1 of hypertrophic scar, keloid was obviously higher than that in surgical scar or normal skin (P < 0.01), decreased from hypertrophic scar, keloid, surgical scar to normal skin. There existed a positive correlation between vessel count and the expression of HO-1 (r = 0. 761, P < 0.01) as well as the number of fibroblastic cells (r = 0. 731, P < 0.01) in the study groups.
  
  
  CONCLUSIONS
  HO-1 might play a important role in the angiogenesis of scar formation. The cause of these changes may be local. Over angiogenesis is one symbol of pathological scar.
