title: Serum superoxide dismutase activity correlates with the components of metabolic syndrome or carotid artery intima-media thickness.
abstract: The activities of the enzymes to eliminate reactive oxygen species prevent the progression of atherosclerosis. We conducted a cross-sectional study among 3234 people that underwent total health check-up service, and studied the relationship between the serum superoxide dismutase (SOD) activity and risk factors of atherosclerosis or carotid artery intima-media thickness (IMT). Serum SOD activity negatively correlated with body mass index (BMI), systolic and diastolic blood pressure, serum triglyceride (TG) concentration and serum glucose concentration. Low serum SOD activity positively correlated with the carotid IMT thickening. But on the other hand, existence of carotid artery plaque positively correlated with serum SOD activity especially among men. Serum SOD activity negatively correlated with the components of metabolic syndrome and low serum SOD activity seems to be an independent risk of the thickening of carotid IMT. On the other hand, serum SOD activity level seems to elevate limitedly but reactively to the status of increased oxidative stress, such as carotid plaque formation.
