氦氖激光对心肌梗死大鼠血清超氧化物歧化酶的影响

The Effect of He-Ne Laser on Serum Superoxide Dismutase of Rats with Myocardial Infarction

目的:探讨氦氖激光对心肌梗死大鼠血清中超氧化物歧化酶(SOD)的影响。方法:以特定的氦氖激光强度、经不同的照射时间照射心肌梗死大鼠心前区,观察血清SOD的改变。结果:氦氖激光照射心肌梗死大鼠心前区10 min和20 min时血清中SOD升高,与对照组比较差异有统计学意义(P<0.05)。结论:氦氖激光照射心前区对于冠心病、心肌缺血的治疗有一定意义。

Objective： To probe into the effect of He-Ne Laser on superoxide dismutase（SOD）in the serum of the rats with myocardial infarction.Methods： The rats with myocardial infarction were irradiated by He-Ne Laser,in different irradiating times and with certain irradiating intensity,to observe changes of serum SOD.Results： Compared with that in the control group,the content of SOD in serum increased（P0.05） when the precordia of rats with myocardial infarction was irradiated by He-Ne Laser for 10 and 20 min.Conclusion： He-Ne Laser irradiation of precordia has certain significance in the treatment of coronary heart disease and myocardial ischemia.
