title: [Experimental study on effect of Buyang Huanwu decoction on arterial blood platelet activating factor content pre- and post-arterial thrombosis of rats].
abstract: OBJECTIVE
  To explore the effect of Buyang Huanwu Decoction (BHD) on arterial blood platelet factor (PAF) content in pre- and post-arterial thrombosis of rats.
  
  
  METHODS
  Male Wistar rats were randomized into 3 groups, the BHD group treated with BHD 32 g/kg, or with BHD 16 g/kg daily for 14 days consecutively, the control group treated with dexamethasone 0.5-1 mg/kg and the blank group treated with distilled water 10 ml/kg. Arterial thrombosis was duplicated in the animals 2 hours after final medication, the blood content of PAF (by bioassay), dry weight (W) and occlusion time (OT) of thrombus, and weight of thrombus/body weight (TW/BW) ratio were observed.
  
  
  RESULTS
  Consecutive BHD treatment could markedly lower the arterial blood content of PAF after thrombosis, increase the OT value of thrombus, reduce the dry weight of thrombus and the TW/BW ratio (P < 0.05), while no influence was found in rats treated with BHD once.
  
  
  CONCLUSIONS
  BHD has certain antagonistic effect on pathologic PAF metabolism, and inhibitory effect on pathogenesis and development of arterial thrombosis.
