title: [Effect of panax notoginseng saponins injection on brain edema in intracerebral hemorrhage rats].
abstract: OBJECTIVE
  To study the effect of panax notoginseng saponins (PNS) in treating hemorrhagic apoplexy at super-early stage in rats.
  
  
  METHODS
  Rat model of hypertension with cerebral hemorrhage was induced by collagenase method. Sixty rats were randomly divided into 5 groups: the sham operated group, model group, PNS high, middle, and low dose group, 12 in each; 4 h after modeling, PNS or normal saline was intraperitoneally injected into the rats every 12 h, the total is 5 times. Contents of water, sodium and potassium ion in brain, and the diameter of hematoma in rats of different groups were measured 24 h and 72 h after modeling.
  
  
  RESULTS
  Compared with the model rats, nerve defect symptoms aggravated, the contents of water and sodium ion in ipsilateral cortex and basal ganglia were significantly higher, the content of potassium ion was lower and the hematoma diameter was obviously less in the PNS-treated rats (all P < 0.05).
  
  
  CONCLUSIONS
  PNS may worsen the brain edema and increase the nerve defect score when it was applied at the early stage of cerebral hemorrhage, but could promote the absorption of hematoma, indicating PNS should be used cautiously in treating patients with large amount of cerebral hemorrhage at super-early stage.
