Study on Technology of Hemal Irradiation by He-Ne Laser to Improve the Erythrocyte Deformability

Objective: To study the changes of erythrocyte deformability after irradiated the intravascular and extravascular by He-Ne laser.Methods: 21 dult albino rabbits have been randomly divided into three groups.Each group was 7.In irradiation groups,the He-Ne Laser has been used to irradiate the ear's intravascular and extravascular of rabbits.Every 24 hours,the irradiation was conducted one time and each time,the irradiation was hold for 50min.The venous blood have been collected at the times of before irradiation,irradiated after first time and seventh time.The index of blood RBC deformation have been detected.The control group was treated at a normal raising condition.Results: In irradiation group,the index of RBC deformation increase significantly(P0.05);In vivo,the permeance rate of He-Ne Laser in vein is 83.5%.Conclusions: After calculating equivalent power,the intravascular irradiation can been instead of extravascular irradiation,increase the erythrocyte deformability,improve the hemokinesis and minicirculation.
