title: [Effect of butylphthalide on the expression of S100 and glial fibrillary acidic protein in a rat model of Alzheimer disease].
abstract: OBJECTIVE
  To determine the expression of S100-beta protein and glial fibrillary acidic protein (GFAP) in hippocampal astrocytes of rats with Alzheimer disease (AD) model rats, and observe the effect of butylphthalide on their expression.
  
  
  METHODS
  Sixty male adult rats were randomized equally into model group, butylphthalide group, and control group, and in the former two groups, AD models were established by injecting beta-amyloid protein 1-40 into the hippocampus. Sixty days later, the rats were sacrificed and the bilateral hippocampuses were taken for immunohistochemistry.
  
  
  RESULTS
  The number of cells positive for S100 and GFAP in the hippocampus in butylphthalide group were significantly higher than that in the control group (P/0.01), but lower than that in the model group (P/0.05).
  
  
  CONCLUSIONS
  The expression of S100 protein and glial fibrillary acidic protein increased significantly in the hippocampal astrocytes of rats with AD, and butylphthalide can inhibit the increase of their expression.
