In vitro He-Ne laser effect on some immunological functions of the polymorphonuclears and monocytes in rabbits.
The aim of this study is to evaluate in vitro the effect of Helium-Neon (He-Ne) laser irradiation on the viability, adherence, phagocytic activity of the polymorphonuclears and monocytes. Also the level of metabolic processes in phagocytizing blood cells, monocytes and polymorphonuclears was estimated and evaluated by the INT-test. Evaluation of the leukocyte adherence, the method of MacGregor was used. Phagocytic activity was examined by classical method using microspherical hydrophilic particles (Hema-particles). He-Ne laser in a small dosage (< or = 0.8 J) increases the leukocyte adherence, after higher laser irradiation dosage (> 1.2 J) the leukocyte adherence is decreased. The laser effect on the phagocytic activity of both types of blood cells, polymorphonuclears and monocytes is similar. Small dosage of the laser irradiation increases the phagocytic activity, and after higher laser irradiation phagocytic activity is decreased. Also the changes of the level of metabolic processes in the phagocytizing cells are very similar with the changes of phagocytic activity. The viability of the blood cells examined after higher laser irradiation is gradually decreased.
