title: Effects of acetylsalicylic acid on serum paraoxonase activity, Ox-LDL, coenzyme Q10 and other oxidative stress markers in healthy volunteers.
abstract: OBJECTIVE
  The aim of the study was to examine the effects of acetylsalicylic acid (ASA) on oxidative stress in healthy volunteers.
  
  
  METHODS
  30 volunteers of which 17 received ASA as 100 mg/day (Group I) and 13 received ASA as 150 mg/day (Group II) for 2 months. Serum paraoxonase 1 (PON1), arylesterase, total antioxidant status (TAS), total oxidant status (TOS), oxidized LDL (Ox-LDL) and coenzyme Q(10) (CoQ(10)) levels were measured before and 1 and 2 months after treatment.
  
  
  RESULTS
  There was no significant differences between the measured parameters of the groups. However, TOS and Ox-LDL levels of group II were significantly reduced after 2 months of treatment (p<0.05).
  
  
  CONCLUSIONS
  Significantly inhibition of LDL oxidation and significantly reduction in TOS levels of group II after 2 months of ASA treatment shows that ASA treatment may contribute to the prevention of atherosclerosis, a beneficial effect which is dose and time dependent.
