Relative expression of hOGG1 DNA repair gene in blood cells of patients under general anaesthesia with ISF. T₁: before anaesthesia; T₂: 2 h after the beginning of anaesthesia and T₃: on the first post-operative day. The horizontal bars indicate median RQ in each sampling time; dotted lines indicate the limits of RQ 0.5 and RQ 1.5. Data were obtained from 18 subjects. P < 0.05: (T₁ = T₂) > T₃.
