title: [Relationship between endothelins, nitric oxide and other endothelial active factors and blood stasis syndrome in patients with atherosclerosis obliterans].
abstract: OBJECTIVE
  To observe the levels of plasma endothelin (ET), nitric oxide (NO), intercellular adhesion molecule (ICAM) and other endothelial active factors, and to investigate the nature of atherosclerosis obliterans (ASO)-blood stasis Syndrome (BSS) from the point of vascular endothelia and molecules.
  
  
  METHODS
  Ninety-eight patients with ASO-BSS were divided into 3 groups (mild, moderate and severe) and 3 clinical Syndrome subtypes (Qi stagnation BSS, Qi deficiency BSS and Damp-Heat BSS). The circulating endothelial count (CEC), ET, NO and other plasma active factors were determined by density gradient method, radioimmunoassay, enzyme immunoassay method.
  
  
  RESULTS
  The patients with ASO-BSS had high CEC and ET levels, low levels of NO, and had alterations of hemorheology, particularly in those with severe BSS and Damp-Heat BSS.
  
  
  CONCLUSIONS
  ASO-BSS patients have endothelial injuries, endothelial dysfunction, and alterations of hemorheology, which may be the pathogenetic mechanism of ASO-BSS. Observation on these parameter changes will be helpful to evaluate severity, to distinguish the clinical types in TCM, and to clarify the nature of BSS.
