[The experimental action of helium-neon laser radiation on the tracheal and bronchial mucosa].

It has been shown that the energy of helium-neonium laser does not affect the tracheal and bronchial mucosa and does not induce tissue irreversible changes under the dose of 358 J/cm2. The sufficient parameters for good treatment are: -4.78 J/cm2, the density of power--7.9 mWt/cm2, the power--0.6 J and time of exposition -1 min.
