CQ10 increased antioxidation (SOD, GSH, GPx, and GR) and reduced oxidation (TBARS) in rats with acute myocardial ischemia-reperfusion injury at same time point. SOD: superoxide dismutase; GSH: glutathione; TBARS: thiobarbituric acid reactive substances; GPx: glutathione peroxidase; GR: glutathione reductase. compared with 2 h in AMI/R group, ; & compared with 24 h in AMI/R group, ; # compared with 72 h in AMI/R group, .
