title: [Effect of T lymphocyte in the acute rejection of liver xenograft].
abstract: OBJECTIVE
  To study whether T cell take part in the acute rejection of liver corcondant xenograft.
  
  
  METHODS
  The orthotopic liver transplantation model introduced by Hariharas was established. In grafts, CD4, CD8 and Fas-L were examined by immunohistochemistry at day 1, 3, 5, 7 post-transplantant respectively, and apoptosis in grafts was observed by histology and TUNEL (Terminal Deoxynucleotidyl Transferse-mediated dUTP nick-end Labelling,).
  
  
  RESULTS
  In xenogenic grafts, T cell infilitration occurred at day 3, peaked at day 5, including CD4, CD8 subsets. The expression of Fas-L was found at day 4, peaked at day 5-6. The more severe the acute rejection is, the more the quantities of the expression of Fas-L is, the more the quantities of apoptosis is in grafts.
  
  
  CONCLUSIONS
  T lymphocytes participate in the acute rejection of liver xenograft.
