Abstract

Background and Aim: SMOKERS are exposed to significant quantities of oxidative factors. The effects of smoking on plasma concentrations of antioxidants and susceptibility to oxidative stress in young subjects are largely unknown. This study was done for comparison of URIC ACID concentration and plasma antioxidant capacity in young SMOKERS and non-smokers.Materials and Methods: In an analytical observational study, a sample of 23 male smoker with history of at least 10 cigarettes per day for 5 years and 21 healthy non smoker male, all aged 40 or under 40 years old, were included voluntarily in the study. All participants were free of major signs and symptoms suggestive of any disease. Fasting blood samples (10 ml) were collected in heparinized tubes just before morning smoking. Plasma samples were isolated and stored at-60oC for later evaluating. In this study, URIC ACID concentration was measured by an enzymatic method. The main methods for evaluation of oxidative stress were: determination of the TOTAL ANTIOXIDANT CAPACITY (TAC) by Ferric reducing/antioxidant power (FRAP) assay, Ellman's reagent for measuring the amount of THIOL GROUPS, and concentration of 2,2-Diphenyl-1- picrylhydrazyl (DPPH) for determination of antiradical activities of plasma. Results: URIC ACID concentrations (mg/dL) in SMOKERS and non-smokers was 6.2±1.5 and 4.5±1.7 respectively (P<0.001). Determination of the TAC (%mol/L) level by FRAP assay showed 980.7±214.4 in SMOKERS and 997.4±156.9 in nonsmokers (P=0.75). Quantitative determination of per-oxiradicals by DPPH assay revealed 12.6%±1.4 in smoker and 15.3%±2.2 in nonsmoker (P=0.37). The plasma levels of THIOL GROUPS (mmol/L) were 281.1±60.9 in SMOKERS and 256.5±57.8 in non-smokers (P=017).Conclusion: Given the role of cigarette smoking as a risk factor for cardiovascular diseases and the role played by oxidative stress in them, measurement of URIC ACID in young smoker subjects represents a marker against tobacco-induced oxidative stress and recommends their timely giving up of smoking.
