Effect of low-intensity laser radiation on cells

Low-intensity (0.89 μ) laser irradiation of mast cells in rat mesentery in various combinations of power and exposure modifies their functional activity. Enhanced degranulation was observed at 18–25 mW beam power and 15–30 sec exposure. The modes of radiation that did not promote degranulation, changed the form of the cells, which indicates a membranotropic effect of low-intensity laser radiation.

Effect of low-intensity extremely high frequency radiation on reproductive function in Wistar rats

The exposure to low-intensity extremely high frequency electromagnetic radiation during spermatogenesis was accompanied by pathological changes, which resulted in degeneration and polymorphism of spermatozoa. The number of newborn rats increased in the progeny of irradiated animals. __________ Translated from Byulleten’ Eksperimental’noi Biologii i Meditsiny, Vol. 142, No. 8, pp. 152–154, August, 2006

Effect of low-intensity laser radiation on leukocyte function

The effect of a He-Ne laser (λ=632.8 nm) on the functional activity of peripheral blood leukocytes is examined by the method of luminol-dependent chemiluminescence. The maximum stimulation of leukocytes is observed in the 0.05–0.15 J/cm² range, being dependent on the leukocyte preparation. In the presence of the photosensitizing agent phthalocyanine the maximum stimulation is observed at lower intensities.

Effect of laser radiation on physicochemical and functional properties of human hemoglobinin vitro

Exposure to laser radiation increases pH and isoelectric point of human hemoglobin solution, improves the acid-base properties, increases affinity for oxygen, and decreases the Bohr effect in comparison with intact hemoglobin. The mechanisms underlying these changes are discussed. Translated fromByulleten’ Eksperimental’noi Biologii i Meditsiny, Vol. 123, No. 1, pp. 15–17, January, 1997

Membranotropic effect of low-intensity laser radiation of the blood

We have examined the effect of a low-intensity laser radiation (wavelength 630 nm, beam power 1 mW) on the aggregability of blood platelets, acidic tolerance of erythrocytes, and the structure of their membranes. Laser radiation suppressed platelet aggregability induced by ATP, epinephrine, collagen, platelet activating factor, and fibrinogen and enhanced the resistance of the erythrocytes. It decreased the microviscosity of lipid bilayer and of the membrane protein-lipid contact regions and slowed down lipid peroxidation. These findings attest to a direct membranotropic effect of laser radiation, which is particularly strong in the protein-lipid contact regions.

Effect of electromagnetic radiation modulated by biostructures on the course of alloxan-induced diabetes mellitus in rats

Exposure of rats with experimental diabetes mellitus to wide-band electromagnetic radiation generated by He-Ne laser and modulated by the pancreas and spleen is informing and phenomenological method prolonging animal life span, normalizing blood glucose level, and promoting regeneration of the pancreas. __________ Translated from Byulleten’ Eksperimental’noi Biologii i Meditsiny, Vol. 143, No. 2, pp. 155–158, February, 2007     

Effect of low-intensity laser irradiation and wideband red light on experimentally ischemized myocardium

The effect of helium-neon laser irradiation and wideband red light on electrical activity of open rat heart was examined after experimentally produced ischemia. The red light applied with the help of optical fibers modified parameters of cardiac electrical activity and intensity of lipid peroxidation in the myocardium. The effects of laser and red light irradiation differed significantly. __________ Translated from Byulleten’ Eksperimental’noi Biologii i Meditsiny, Vol. 145, No. 5, pp. 509–511, May, 2008     

Effect of low-intensity infrared laser on the healing of dermatome wounds

Changes in the microvessels, consisting in their dilatation and accelerated formation, and a shift of the peak of epitheliocyte proliferative activity are found to be the structural basis of the stimulating effect of infrared magnetic laser. Morphologic changes in connective-tissue cells determine both the proper development of the connective-tissue carcass, primarily of the fibroblasts, and the barrier protective and regulatory function of such cells as macrophages, neutrophils, plasma cells, eosinophils, and, last but not least, mast cells. Morphologic changes occurring during irradiation according to optimal schemes indicate activation of specific cell functions and are observed at earlier times.
