Objective To study the effect of low-power He-Ne laser irradiation on precordial region of Wistar rat on the inner-diameter and the density of myocardial capillaries and the number of the pinocytotic vesicles in the endothelium cells of myocardial capillaries. 目的探求氦氖(HeNe)激光照射大鼠心前区,对心肌毛细血管的内径和密度以及毛细血管管壁内皮细胞胞饮小泡数量的影响。
Effect on the Ratio of Myocardial Capillary opening by He Ne Laser Irradiation on Precordial Region of Wistar Rat He-Ne激光照射大鼠心前区对心肌毛细血管开放率的影响
Objective To determine the effect of low power He Ne laser irradiation on expression of myocardial VEGF in precordial region of wistar rat. Methods VEGF expression in myocardium was studied by immunohistochemical methods, RT PCR and computer image analysis. 目的探求低能量氦氖激光照射大鼠心前区,对心肌血管内皮生长因子(VEGF)表达的影响。
