title: [Effects of simvastatin on plasma SOD, MDA and 8-iso-PGF2α in patients with stable angina].
abstract: To observe the effects of simvastatin on plasma superoxide dismutase (SOD), malonaldehyde (MDA) and 8-iso-prostaglandin F2α (8-iso-PGF2α) as well as uric acid (UA) and serum lipids in patients with stable angina. METHODS Eighty-five patients with stable angina were divided into 4 groups, including hyperlipemia treatment group (HLT), hyperlipemia control group (HLC), normolipemia treatment group (NLT), and normolipemia control group (NLC). All the patients received routine treatment according to the guideline of CHD treatment, and those in the treatment groups were given Simvastatin (40 mg) every night, whereas those in the control group received placebo for 3 months. Before and after the treatments, the levels of plasma 8-iso-PGF2α were measured by enzyme-linked immunosorbent assay, and the plasma levels of SOD and MDA were detected by colorimetric method. LDL, HDL, TC, TG, and UA were also measured biochemically. RESULTS Compared with the control group, both of the treatment groups showed significantly increased levels of SOD and decreased MDA, 8-iso-PGF2α, UA and plasma lipids after the treatments (P<0.05). CONCLUSION In patients with coronary heart disease, simvastatins can decrease plasma lipids, inhibit lipid peroxidations, and promote the clearance of free radicals, thereby alleviating the oxidative stress.
