title: Dynamic changes in serum level of nitric oxide and its mechanisms in rats with traumatic shock.
abstract: OBJECTIVE
  To investigate the dynamic changes of serum nitric oxide (NO) level and its mechanisms in rats in traumatic shock.
  
  
  METHODS
  Rat models of traumatic shock were established by fracturing the posterior limb of the rats. Serum levels of nitrate/nitrite were measured with the method described by Griess.
  
  
  RESULTS
  No significant changes in serum NO level took place during traumatic shock. One hour after resuscitation, however, serum NO level first underwent marked decline and then increased to the peak level at 6 h after resuscitation, retaining a high level till 24 h after resuscitation. No obvious changes of serum NO levels were observed in rats without resuscitation.
  
  
  CONCLUSIONS
  Serum NO level does not significantly alter during traumatic shock, while after resuscitation, NO level increases after transient decrease, possibly due to reperfusion injury.
