[Indicators of the activity of the immune system during laser therapy of vasomotor rhinitis].

Helium-neon laser LH-75 was used to treat 60 inbred mice and 62 patients with vasomotor rhinitis. The patients were given 10 laser sessions. In animals, all responses of T-lymphocytes were modified. Cyclic changes that developed during laser irradiation were accompanied by immunity suppression or activation. In patients, the count of T- and B-lymphocytes and the leucocyte migration inhibition reaction were measured. The patients with vasomotor rhinitis showed a significant increase of T-lymphocytes and a higher capacity of T-cells to form the migration inhibition factor. The efficacy of laser therapy of vasomotor rhinitis became optimal on irradiation day 6 or 7 and reached a maximum on day 10.
