The interaction between the low power light and the tissues is not clear. We chose the blood and the erythrocytes because, the first one is the plenty and most necessary for life and the erythrocyte is the simplest cell. Light from different sources, HeNe laser, 675 nm laser, 785 nm laser, 904 nm GaAs laser and 940 nm light emitting diode were used for irradiation of blood. We found a threshold time form which these lights induce changes in the normal blood cell. Results may be explained by considering the differences between the moment of inertia of the lipid configuration on the membrane of the cell.
We show that low levels of no coherent and no polarized infrared light induce modifications in human blood cells. An infrared GaAs 6 mW power output light emitting diode irradiate healthy erythrocytes for times from 1 to 30 minutes. We found a threshold time form which light induces changes in normal blood cells, changing its morphology and distribution. Irradiated fresh human blood from 82 healthy patients showed modifications independent of patient's age. This phenomenon may be explained by considering the rotational movement of lipids in both surfaces of lipid bilayer, their magnetic field and interaction with iron hemoglobin.
