title: [Therapeutic effect of high-density lipoprotein of human plasma on rat endotoxemia].
abstract: OBJECTIVE
  To investigate the therapeutic effect of high-density lipoprotein (HDL) of human plasma on rat endotoxemia.
  
  
  METHODS
  Rats were divided into 2 groups randomly, the treated group received bolus intravenous endotoxin (500 EU/kg), then followed by a bolus HDL (75 mg/kg) intravenously as their blood pressure decreased obviously. The control group just received bolus intravenously endotoxin (500 EU/kg) without HDL. Blood pressure, survival time, the concentration of TNF and the levels of endotoxin in plasma were determined using radioimmunoassay and limulus lysate test.
  
  
  RESULTS
  The decrease of blood pressure was obviously attenuated (P < 0.01), the survival time was significantly increased (P < 0.01) and the concentration of plasma TNF was decreased (P < 0.05) in the treated group, compared with those in the control group. The levels of endotoxin were of no significant difference between the two groups (P > 0.05).
  
  
  CONCLUSIONS
  HDL of human plasma has obvious therapeutic effect on rat endotoxemia it could enhance the resistance of rats to endotoxemia, and the mechanism therein may be related to the inhibition of the release of TNF.
