title: [Clinical observation of the superoxide dismutase (SOD) and lipid peroxide (LPO) changes in oral-maxillofacial surgical patients].
abstract: This article reports examination of superoxide dismutase (SOD) activity in RBC and lipid peroxide (LPO) content in the plasma of the oral-maxillofacial operation patients. The results showed that the LPO content in postoperation ascended remarkably compared with pre-operation (P < 0.001) and that the SOD activity rose also (P < 0.05). It was discovered that the difference of LPO content between the pre-operation and post-operation was closely relative with the difference of SOD activity, the operative time and the operation method (intra- or extra-oral approach). The results demonstrated that the operative damage resulted in the increasing of the reactivity of superoxide radical and LPO and that the rising of SOD activity was probably the compensation of the body.
