title: [Effects of nitric oxide on platelet function in burned rats].
abstract: OBJECTIVE
  To investigate the effects of nitric oxide (NO) on rat platelet function after burn injury.
  
  
  METHODS
  Wistar rats with 30% TBSA full thickness burns were used as model, indices of platelet functions including platelet aggregation rate in first minute (PAR-1), maximal platelet aggregation rate (PAR-m), platelet dissipation rate (PDR) and platelet adhesion rate (PAR) were determined in four groups, namely burn control (B), NO donor (sin-1), NO synthesis inhibitor (L-NAME) and the normal control (C).
  
  
  RESULTS
  The PAR-1, PAR-m and PAR were significantly increased and the PDR was decreased remarkably after burn injury. In sin-1 group the PAR-1, PAR-m and PAR were obviously lower and the PDR was higher than that of B group (P < 0.05-0.01). In L-NAME group the PAR-1 was higher and the PDR was lower as compared with B group, but the PAR-m and PAR showed no significant differences between two groups.
  
  
  CONCLUSIONS
  The ability of platelet adhesion and aggregation induced by activated platelet are increased after burn injury. NO can partially reduce the degree of platelet activation and inhibit platelet aggregation. Moreover, it may dissipate aggregated platelets.
