Abstract

Reactive oxygen and nitrogen species have been implicated in the pathogenesis of noise-induced hearing loss. In this case-control study, we investigated the oxidative and antioxidative status of erythrocytes from workers in noisy workplace. Blood samples of 127 workers in noisy workplace (WNW) and 117 workers in non-noisy workplace (WNNW) from the same company were taken into tubes with potassium EDTA as anticoagulant in order to obtain hemolysate. Total superoxide dismutase (SOD) and catalase (CAT) activities as the enzymes of antioxidative defense mechanism in the erythrocytes together with malondialdehyde (MDA) as the lipid peroxidation index and total nitric oxide (NO) as an index for nitrogen species analyses were performed by spectrophotometric methods.
