Özet

Aim. It has been suggested that cancer incidence is high in subjects with scoliosis who are relatively more often exposed to X-ray for diagnosis and follow-up. X-ray is a kind of ionizing radiation and leads to formation of oxygen free radicals which are capable of damage to DNA, thus altered gen expression and mutation. p53 tumor suppressor gene plays a crucial role in the damage response. It controls the checkpoint of cell cycle and redirects the cell metabolism to either repair of damaged DNA or apoptosis as response to DNA damage. The aim of the present study was to examine serum levels of 8-Hydroxydeoxyguanosine (8-OHdG), a strongly mutagenic product of oxidative DNA damage, p53, superoxide dismutase (SOD) and glutathione peroxidase (G-Px), as antioxidant activity, in children with scoliosis who had got whole spine radiograph two times during the last year.
