Analysis on interaction effect of terahertz radiation with living biology system

In the first place, the coherent collective vibration models of the living biological molecule system (e.g. DNA and protion) are analyzed in this paper. Then we have analyzed yet order-disordering variance due to resonance effect and the nonlinear behavior of terahertz radialion(THR)-biological system interaction. The analytic results show that the interaction between the living biological system and THR can produce resonance excitation effect, and so the system can be produced under further action of the laser. In addition, we have analyzed the nonlinear properties of the THR bio-molecule interaction and explained the mutagenesis effects of THR. The theoretic analysis is consistent with the results of THR biological test.

Analysis on the interaction of laser on fibrinogen clots in blood and its clinical practice

In this paper, C-C bond of fibrinogen is considered as a inharmonic oscillator system. It analyses on the interaction of laser on C-C bond of fibrinogen. It point that intra-vascular laser irradiation can reduce the fibrinogen clot in blood and improve blood flow. It is explained by quantum mechanics and simulated by Matlab. It is fit with the clinical effect.

Microscopic mechanism analysis on rheology and harmful effects by low level laser irradiation of blood

The microscopic mechanism on rheology and harmful effects of low level laser irradiation of blood were analyzed by Quantum theory. The analyzed results showed that laser may resolve fibrin clot, then the property of rheology of blood is improved; and some bonds of the cholesterol in blood were fractured by low level laser (abbreviate LLL) , hence the ratio of membrane cholesterol/membrane phosp-hatide of red cell were reduced, then blood circulation can be improved. So low level laser irradiated blood possess the action of mending rheology of blood. But our analyses point out that LLL may cut off some bonds of living biomolecule (e.g. Protein molecule) yet, then some normal protein may emerged denaturation, so normal cells in blood may be destroyed, namely low level laser irradiation can produce the harmful effects on blood. This paper criticized the viewpoint intravascular low level laser irradiation (abbreviate ILLLI) have not action.

The analysis on the mechanism of the energy transfer of couple structure of the core/shell quantum dots and biomolecule

It was found that core/shell quantum dots coupled with the structure of biological molecules, appear to accept the role of light to stimulate the part (donor),and then received no radiation in the form of energy to pass to the structure of some other molecules(acceptor), which appeared for the donor fluorescence quenching and the fluorescence activated receptor. It should be noted that in quantum dots coupled with molecular structure of biologcal energy transfer for its application in the biologcal sciences is very important. But its mechanism of energy transfer theory analysis is not enough. Now we generally agreed that quantum dots coupled with biologcal molecules in the structure of the transferring mechanism is the dipole-dipole interaction mechanism (Forster theory). However, Forster dipole-dipole interaction theory generally applies to weak coupling and incoherent system. As quantum dots coupled with the molecular structure of biologcal is complex, coupling between the system elements may be stronger coupled and has a coherence. Therefore, Forster dipole-dipole interaction theory does not apply. We believe that should be applied Redfield coherent exciton-dipole interactions or strong interactions between the exciton theory. If biomolecules coupled quantum dot structure with a high degree of coherence and the existence of anharmonic interactions, in this case perhaps the energy of this system will soliton transmission mechanism. This is only our speculation.

Laser induced fluorescence effect mechanism analysis of biomolecule

In this paper, according to Frohlich biological Bose condensation theory, the living biological system is a very high coherence system, so we believe that the system is a set of some same electric dipole oscillator; and we take this system as double energy level, the two energy level model is simple and effective model for mentioned system above. On the basis of the two energy level model of the biomolecule, the micromechananism of fluorescence effects on account of laser acting on living biomolecule system was analyzed by quantum theory(i.e. the dressed stats of biomolecule in laser field was adopted under dipole approximation). In this paper, some results of corresponding experiment were explained by means of the dressed state theory and the dipole-dipole interactions theory (Foster theory). Our theory can explain some results of corresponding experiments.

Experimental study and theoretical analysis of lethal effects and stimulating effects of laser irradiation on biologically suspended cells

CO2 laser and He-Ne laser were used to irradiate the biologically suspended cell respectively, i.e. industrial saccharomyces cerevisiae AS Sacchromyce2.1189. Experimental results show that the increase of CO2 laser temperature was fast, and there was a clear lethal effect. The temperature of He-Ne laser was almost not up, and there was no lethal effect, but mainly the stimulating effect. In this paper, the lethal effect and the stimulating effect of experimental results were analyzed by fractal theory and quantum theory. The theoretical analysis was consistent with the experimental results.

Microscopic mechanism analyses on influence of metabolism of erythrocyte membrane-lipid etc. by LLLIB

Some cases with cerebral infarction were treated by He-Ne laser irradiation on blood. In the treatment before and after, membrane-cholesterol(C)/membrane-phosphatide(P), membrane fluidity(F) and deformability of erythrocyte were determined. The results showed that low level laser irradiation on blood (LLLIB) can sure reduce the ratio of (C)/(P), can heighten fluidity and improve deformability of erythrocyte .Thus the metabolism ability of erythrocyte membrane-lipid ,the blood circulation and the properties of hemorheology can be improved. In this paper, the microscopic mechanism of those aforesaid action effects by low level laser irradiation on blood were analyzed by means of Quantum theory and some corresponding models.
