Abstract:
Objective:To investigate the effect of fastigial nucleus stimulation(FNS) on preventing oxidative damage from myocardium after acute myocardial infarction in rats.Methods:Wistar rats were randomly divided into acute myocardial infarction(AMI),FNS before AMI model was made(FNS+AMI),bilateral fastigial nucleus lesion(FNL) before AMI(FNL+AMI) groups.At 24 hours after coronary ligation,blood samples and left ventricular myocardium were obtained for measurment of the activity of lactic dehydrogenase(LDH) and creatine phosphokinase(CK) in serum,as well as myocardial infarct size.At the same time,the malondialdehyde(MDA) level,total anti-oxidative capability (TAOC) and superoxide dismutase(SOD) activity in myocardium were measured too.Results:LDH,CK activities and MDA level in FNS+AMI group were significantly lower than that in AMI group( P 0.05).Conclusion:FNS can attenuate the damage of myocardium from infarct heart and reduce myocardial infarct size.The mechanism of the protective effect coming from FNS may be related to its antioxidative role.
