[Helium-neon laser radiation as an inducer of interferon formation]

Helium-neon laser has first been shown to be an active interferon inducer. Marked induction was found at various radiation power (1, 6-7, 20 MW) and at various radiation exposures: from 1 sec to 1 min both for single (up to 512 units/ml) and repeated (up to 1024 units/ml) effects on leukocytes of the donor blood. The major part of interferon was shown to be acid-labile and a lesser part was acid-stable alpha- and gamma-interferons. The above data are of both practical and theoretical importance for the elucidation of the pathogenetic mechanisms of positive therapeutic effect of this light on living beings.
