The effect of low-intensity laser radiation on rat brain capillaries]

The dose-dependent action of the low-intensive He-Ne laser on the capillaries of the temporal area of the brain which were revealed by Mg ATPase has been determined. Laser radiation during 0.5-15 min provoked a complex of the activity of the enzymes in the vessels with density latent action of the factor. Subsequent increasing of the exposition (from 30 min to hours) bring to the opposite effect.
