The Research On Physical Analysis Of The Intravascular Low-Reaction-Level Laser Irradiation Therapy And The Clincal Application

Based on the clinic results that the intravascular low-reaction-level laser irradiation therapy (ILLLIT) can greatly improve the index of hemortheologic characteristics, theoretic study of this therapy mechanism was made, especially the mechanism of the interaction between laser and the main component of blood so that we give out the primary explanation of ILLLIT mechanism.First of all, according to the characteristics of ILLLIT, the quantum mechanical model of interaction between low-reaction-ievel laser and H-baud is established. What's more, the influence of low-reaction-level laser to crytlirocyte aggregation index is studies. The theoretic results show that the H-band of erythrocyte will break if it is further irradiated by laser, which will results in the gradual ionization of erythrocyte congeries and reduction of erythrocyte f-ggrctiation index. In this way, the index of whole blood viscosity iow share ami crythrocyle sedimentation rate are improved significantly.In this paper, we first introduce fractal theory combining with the scale relation. We establish the fractal form of protein molecule's clastic modulus and fracton dimensionality. The influence of low-reaction-level laser to erythrocyte defonnabilily is also investigated. The analysis shows that due to laser photon energy making the protein molecules' electron energy level of erythrocyte changed, the protein molecules' fracton dimensionality increase. It further decreases the erythrocyte's elastic modulus. In this way, we can explain the reason that the erythrocyte deformability enhances by ILLLIT while the whole blood viscosity in high share decreases.According to the theory of electron-conformation interaction, we establish the quantum mechanical model of the relation between low-reaction-level laser and Plasminogen-Plasmin system. We also study the influence of low-reaction-level laser to blood fibrinogen. Hereby the conclusions are drawed that the low-reaction-level laser can increases the content of fibrinolysis so that fibrinogen is diseased. As the result, the plasma viscosity and the degree of blood platelets' aggregation are reduced which can explain the improvement of thrombus dissolution by the treatment of ILLLIT.At last, we also study the theoretical analysis of critical hyaline cortex emulsification with Nd:YAG laser.
