| Summary: | ABSTRACT
Active smokers are exposed to reactive free radicals that are present in cigarette smoke. Oxygen free radicals,
including superoxide, hydroxyl radicals, peroxyl radical hydrogen peroxide and singlet oxygen, are highly reactive
species that can cause a wide spectrum of cell damage including enzyme inactivation, lipid peroxidation, protein and
lipoprotein oxidation, and DNA damage. Free radicals are believed to be involved in the pathogenesis of
cardiovascular diseases and cancer. The purpose of the present study was to measure the total antioxidant status
(TAS) in active cigarette smoking individuals in Mosul city. Twenty active smokers and twenty nonsmokers
participated1in the study. Blood sample was taken from each individual and the TAS had been measured in the sera
using the Cayman chemical antioxidant assay kit (USA). The results obtained from the study revealed a significant
(P<0.001) reduction of the TAS in the smoker’s group as compared with the non-smoker’s group. In conclusion,
smokers possess low TAS than non smokers which may be due to the presence of high amounts of free radicals in
cigarette smoke that generate an oxidative stress in the smoker’s body that may cause exhaustion of antioxidants of
the body. |
