[The clinico-experimental validation of the use of low-intensity laser radiation for the treatment of exacerbated recurrent herpetic stomatitis in children].

Experimental data are presented, validating the use of low-intensity laser irradiation at a wave length of 633 nm for the treatment of chronic recurrent herpetic stomatitis. Clinical trials were carried out in 167 children. Laser exposure with the optimal stimulating parameters was found to be an effective means for the treatment of children suffering from this condition.

[Effect of continuous and modulated laser radiation on the activity of enzymes of glutamic acid metabolism in rat tissues].

A comparative study was made of the effect of continuous and modulated laser radiation on activity of aspartate aminotransferase and glutamate dehydrogenase in the brain and liver of rats. The impulse laser radiation has proved to be most effective with respect to the parameters under study at modulation frequencies of 10 and 50 Hz.

[Changes in the ATP level and surface-adhesive properties of cultured human cells after laser irradiation at a near UV-spectrum].

The ATP content of human fibroblasts increases or decreases depending on the mode of exposure (local and whole-body irradiation at 180 and 8 mW/cm2, respectively). Irradiation gives rise to conjugative changes in the monolayer density of cells and ATP accumulation in them.

[Effect of local laser irradiation on the activity of enzymes of glutamic acid metabolism in rat tissues].

In experiments in vivo it was shown that local laser irradiation of the parietal region of the rat head changed the activity of principal enzymes of glutamic acid metabolism both in the brain and in the liver, whereas peripheral irradiation of epigastric region caused changes in the activity of the studied enzymes in the affected site only.

[Enzyme activity of glutamic acid metabolism and the Krebs cycle in the brain of rats laser-irradiated against a background of altered adrenoreceptor function].

In the in vivo experiments it was demonstrated that the effect of a helium-neon laser (lambda = 632.8 nm), at the background of altered functional status of adrenoreceptors, changes the activity of some enzymes of the glutamic acid metabolism and the Krebs cycle. This may be attributed to both the direct effect of laser radiation and the indirect effect via the adrenergic system.
