				        	To investigate  the  temporal  variation  of  cell  mediated  immunity  in  injured  tissue  of  maxillofacial  firearm  trauma.  Cells  expressing  messenger  RNA(mRNA)  for  IL  2  were  demonstrated  by  dot  blotting  and  in  situ  hybrization  in injured  tissue of  maxillofacial  trauma inflicted by  bullet,  in  conjunction  with  immunohistochemistry  for  IL  2  in  normal  and  postinjury  conditions.  It  was  found  that,  apart from  a  transient eleratim in level  within  24h  post injury, both  IL  2  production  and  IL  2  mRNA  expression  were  consistently  suppressed  in  cells  at the site of  the  wound  compared  with  the  normal.  The  changes  in the tissues of   indirect  injury  by  the projectile   were  significant.  These  results indicate  that  the  cell-mediated  immunity  was suppressed  in  maxillofacial  firearm  trauma  and  the  principal  cellular  abnormalities  that  resulted  in altered  T  cell  activation  and  IL  2  production  postinjury  was  downregulation of mRNA before  IL  2  gene  transcription.  It  also  suggested  that  the  indirect  injury  by  projectile  contribute  mainly  to  the  depression  of  cell  mediated   immunity.
