| 摘 要： | 目的：探讨低强度He-Ne激光照射大鼠心前区对心肌毛细血管开放情况的影响。方法：雌性Wistar大鼠6只，随机等分为对照组和激光照射组。以60．5J/cm^2的He-Ne激光垂直照射激光照射组大鼠心前区，每天1次，连续照射10天，超薄切片透射电镜下观察左心室近心内膜侧，近心外膜侧心肌中直径＜10μm微血管的开放情况。结果：照射组心肌内层毛细血管开放率（70．3％）明显高于对照组（55．6％)，P＜0．05.结论：以剂量为60．5J/cm^的He-Ne激光照射心前区，能使心肌毛细血管的开放率明显增高。

| Abstract: | Objective In order to research for effect on the ratio of myocardial capillaries-opening by He-Ne laser irradiation on precordial region of Wistar Rat.Methods With applying electron microscope, we studied the changes of myocardial capillaries-opening after He-Ne laser with the dose of 60.5 J/cm2 to irradiate. The rats were divided into control(n=3) and irradiated groups.Results Observing capillaries (＜10 μm) in anterior wall of the left ventricle, the ratio of capillaries-opening in irradicated group（70.26%） was higher than in control group（55.56%） in the internal layer of myocardium.Conclusions The results indicated that the ratio of myocardial capillaries-opening was significantly heightened by He-Ne laser irradiation. |
