[Effect of laser irradiation on the serological and morphological indices of experimental immune reactivity (a preliminary report)].

The authors examined guinea pigs, irradiated for a period of six days with helium-neon lazer according to a scheme, proposed by them. They determined the changes in the complement serum activity, blood level of heparine and histamine as well as histologic changes in adrenals, liver and spleen. When they compared the control animals (nonirradiated) with the experimental animals, they established a statisticaly significant elevation of the complement activity in serum, a tendency to lowering of histamine with an increase of heparine and hyperplastic reaction in zona glomerulosa of the adrenals. The obtained results suggested stimulation of immune mechanisms with antiallergic and antinflammatory effect.
