title: [The detection and significance of human papilloma virus 11b virus like particles and its serum antibody in juvenile larynx papilloma].
abstract: OBJECTIVE
  To study the relationship between human papilloma virus 11b virus like particles (HPV11bVLPS) serum antibody and the development and prognosis of juvenile larynx papilloma (JLP).
  
  
  METHODS
  Enzyme linked immunosorbent assay (ELISA) was used to detect the serum HPV11bVLP antibody (Ab) of 46 JLP's samples in different stage and 20 controls using HPV11bVLPS which was produced by recombinant bacilovirus in insect cells. Grouping: A: control group (n = 20); B: the time of onset was 1 years (n = 15); C: the time of onset was 2 years (n = 15); the patients were followed-up 1 year without recurrence (n = 8); E: The patients were followed-up 2 years without recurrence (n = 8).
  
  
  RESULTS
  A value of HPV11bVLP Ab among A, B, C, D, E. group were: (0.073 +/- 0.035); (0.120 +/- 0.049); (0.137 +/- 0.057); (0.518 +/- 0.122); (0.557 +/- 0.144). There was a significant difference between JLP patients and the control group (P < 0.05). The level of HPV11bVLP Ab in (D + E) group (0.534 +/- 0.132) was higher than (B + C) group (0.128 +/- 0.053) (t = 14.90, P < 0.001).
  
  
  CONCLUSIONS
  The results suggested that HPV serum antibody was produced in JLP with HPV infection. There is close relationship between the development and prognosis of the disease and the level of HPV11Ab in serum. The assay of serum HPV11bVLPAb and HPV-VLP could be used as immunological study of HPV11-infection associated disease.
