Oxidative stress and antioxidants markers in individuals with thyroid hormones dysfunction

Introduction and aim. Thyroid hormone abnormalities have been associated with oxidative changes in human beings. The aim of the study was to evaluate the oxidative stress marker and antioxidants status in individuals with thyroid hormone dysfunction in Ekiti State. Material and methods. A total of eighty samples were recruited in this study comprising forty subjects with thyroid hormones dysfunction and forty apparently healthy controls. Malondialdehyde (MDA), reduced glutathione (GSH) and catalase were determined spectrophotometerically. Results. MDA was non-significantly higher (p>0.05) in subjects (4.33±0.84 nmol/mL) compared with control (4.12±0.63 nmol/mL), catalase was non-significantly higher (p>0.05) in subjects (199.36±20.21 µm/mL) compared with control (181.55±16.61 µm/mL), while GSH was significantly lower (p
