title: [The intervention of reduced glutathione in neutrophil activation in the process of extracorporeal circulation].
abstract: OBJECTIVE
  To study the intervention of reduced glutathione for neutrophil activation in the process of extracorporeal circulation.
  
  
  METHODS
  20 congenital heart disease children aged from 6 to 12 years were selected randomly, divided into control group and interventional group, patients of interventional group were added reduced glutathione (30 mg/kg) in priming fluid, then phlebotomized on the time of 24 hours before operation, 20 minutes after CPB, rewarming, the end of CPB, 4 hours after operation, 24 hours after operation. After separated neutrophil, we distilled nuclear protein and mensurated the activation of nuclear factor-kappaB by EMSA, assayed the expression of ICAM-1. by immunohistochemistry.
  
  
  RESULTS
  Neutrophil nuclear factor-kappaB has been activated on the time of 20 minutes after CPB, arrives at the top on the time of rewarming, and resumes 24 hours after operation; ICAM-1 expresses on the time of rewarming, arrives at the top 4 hours after operation in control group. The data of interventional group is lower than the control group.
  
  
  CONCLUSIONS
  Neutrophil nuclear factor-kappaB is activated and ICAM-1 is expressed in the process of extracorporeal circulation and play an important role in the inflammatory response happening in extracorporeal circulation, which could be relieved by reduced glutathione.
