title: [Comparative proteomic analysis of hippocampus between  chronic cerebral ischemia rats and normal controls].
abstract: OBJECTIVE
  To explore the pathogenesis of brain damage after chronic cerebral ischemia through analysis of the differences in proteins expression in hippocampus between chronic cerebral ischemia rats and normal rats.
  
  
  METHODS
  The chronic cerebral ischemia model was established by ligating the bilateral common carotid arteries.Twenty rats were randomly divided into a model group (n=10)and a sham operation group(n=10). Four weeks later, the differences of proteins expression in hippocampus between model group and sham operation group were analyzed by two dimensional polyacryalmide gel electrophoresis and ultraflex TOF/TOF mass spectrograph.
  
  
  RESULTS
  Compared to the sham operation group, the expressions of 4 proteins were up-regulated and that of 2 proteins were down-regulated in the model group. Six proteins were identified by ultraflex TOF/TOF, which were ubiquitin carboxy-terminal hydrolase L1; Dynamin-1; TMF regulated nuclear protein-like, partial; ATP synthase; rCG50513, isoform CRA_a; and expressed sequence AU016693, isoform CRA_b.
  
  
  CONCLUSIONS
  Well-resolved and reproducible 2-DE patterns of chronic cerebral ischemia rats were established. Six proteins that correlate with nerve damage after chronic cerebral ischemia are identified.
