半导体激光血管内照射对健康兔红细胞变形能力的影响

The effects of red cell deformability by intravascular diode laser irradiation

本研究以健康兔为对象 ,随机分为照射组和对照组 ,用半导体激光 (波长 6 5 0nm)进行血管内照射 ,采用新的激光衍射法 ,用红细胞变形仪检测红细胞变形指数 ,研究半导体激光血管内照射对红细胞变形能力的影响。结果表明 :半导体激光血管内照射能改善红细胞膜的粘弹性 ,有利于提高红细胞的变形能力。这从另一角度证明弱激光血管内照射能降低血粘度 。

In this paper,the new method of laser diffraction is used to study of red cell deformability by intravascular diode laser irradiation.Result showed that viscoelasticity of red cell menbrane is improved,the deformability of red cell is raised.
