title: [Effects of quinacrine on gut-origin bacteria/endotoxin translocation in rats with gut ischemia/reperfusion injury].
abstract: OBJECTIVE
  To explore the influence of quinacrine, which is an inhibitor of phospholipase A2, on gut-origin bacteria/endotoxin translocation in rats with gut ischemia/reperfusion injury.
  
  
  METHODS
  Forty-two Wistar rats were randomly divided into normal control (C, n = 6), gut ischemia/reperfusion injury control (IC, n = 12), quinacrine use at 3 hours after the injury(3 h, n = 12), and quinacrine use at 12 hours after the injury (12 h, n = 12) groups. The contents of blood endotoxin and TNF alpha in venae cavae and portal vein were measured in all groups. At the same time, tissue samples from mesenteric lymph nodes, liver, lungs and kidneys were harvested for bacterial culture.
  
  
  RESULTS
  Plasma contents of endotoxin and TNF alpha were lowered in both quinacrine treatment groups (P < 0.01). The incidence of bacterial/endotoxin translocation was decreased by quinacrine use in mesenteric lymph nodes, lungs, liver and kidneys after the injury (P < 0.05 approximately 0.01).
  
  
  CONCLUSIONS
  Early application of quinacrine in Wistar rats inflicted by gut ischemia reperfusion injury could obviously lower bacterial/endotoxin translocation and ameliorate the release of pro-inflammatory mediators and cytokines, thus attenuating injury to remote organs.
