title: [Changes of serum cytokine caused by acute paraquat poisoning].
abstract: OBJECTIVE
  To observe the change of cytokine interleukin IL-1 beta, IL-6, IL-10, tumor necrosis factor-alpha (TNF-alpha) occurred in acute paraquat (PQ) poisoning rats and to investigate the mechanism of acute lung injury caused by paraquat (PQ) poisoning.
  
  
  METHODS
  All 72 healthy adult Wistar rats were random assigned into normal control groups, paraquat high dose group (120 mg/kg), paraquat middle dose (60 mg/kg) group, paraquat low dose group (30 mg/kg). Three observing periods of time included 8, 24, 72 h and the standards of TNF-alpha, IL-1 beta, IL-6, IL-10 were determined.
  
  
  RESULTS
  Every index of the PQ group was significantly higher than that in the NS group at the same period of time (P<0.05 or P<0.01). In the 72 h group, the high dose group was significantly higher than the middle and low dose group (P<0.05), and there was no significantly difference between the middle and low dose group (P>0.05). For the comparison of index in the same dose group, the group of 72 h was much higher than 8 h group and 24 h group (P<0.05), and there was no difference between the 8h group and 24 h group (P>0.05).
  
  
  CONCLUSIONS
  The cytokine may play an important role in paraquat-induced acute lung tissue injury.
