title: [Effects of Nao-Yi-An granule on activity of cytochrome c oxidase in hippocampus of experimental intracerebral hemorrhagic rats].
abstract: OBJECTIVE
  To explore the neuronal protective effects of a traditional Chinese medicine complex Nao-Yi-An granule(NYA) on experimental intracerebral hemorrhage(ICH) in rats.
  
  
  METHODS
  Eighty collagenase-induced ICH rats were used. At 12 h, 24 h, 2 d, 4 d, 7 d, cytochrome c oxidase(CO) activity was measured with histochemistry combined with gray scale scanning. Pyramidal cell(PC) counting was also employed following Nissl's staining.
  
  
  RESULTS
  The CO activities in NYA-treated group were less than those in model control group, and the neuronal loss was less in NYA-treated group than that in model control group.
  
  
  CONCLUSIONS
  The neuronal protective mechanism of NYA following ICH may be related with its maintaining activity of cytochrome c oxidase, which contributes to improving cellular aerobic metabolism and increasing energy supply for cells.
