目的：探讨磁场对缺氧性心肌损伤大鼠心肌MDA含量变化的影响。方法：本实验将大鼠随机分为四组：空白对照组、磁作用对照组、缺氧性心肌损伤组、缺氧性心肌损伤磁场治疗组。采用硫代巴比妥酸法测定各组大鼠心肌MDA含量。结果：心肌MDA含量，缺氧性心肌损伤磁场治疗组明显低于缺氧性心肌损伤组（P＜0．01）。结论：磁场对缺氧性心肌损伤大鼠心肌MDA含量具有明显降低的作用。初步证实，磁砀对缺氧性心肌损伤大鼠心肌具有一定的保护作用。进而表明，磁场对克山病心肌具有一定的保护作用。
Objective: To investigate the effect of magnetic field on the content of myocardial MDA in rats with hypoxic myocardial injury. Methods: In this experiment, the rats were randomly divided into four groups: blank control group, magnetic control group, hypoxic myocardial injury group, and hypoxic myocardial injury magnetic field treatment group. Thiobarbituric acid method was used to determine the myocardial MDA content in each group. Results: The levels of myocardial MDA and hypoxic myocardial injury in the magnetic field treatment group were significantly lower than those in the hypoxic myocardial injury group (P <0.01). Conclusion: The magnetic field significantly reduces the content of MDA in myocardium of rats with hypoxic myocardial injury. Preliminary confirmed that Magpie on hypoxic myocardial injury in rats with myocardial protective effect. Furthermore, it shows that magnetic field has a certain protective effect on Keshan disease.
