[Changes in lectin-induced chemiluminescence of neutrophilic granulocytes after irradiation of blood with helium-neon lasers].

: Blood obtained from 33 healthy donors was irradiated with He-Ne laser. During this process the count of segmented neutrophils decreased, while the content of radioimmunologically determined leukotriene B4 and thromboxane B2 increased in the other neutrophils. Application of mannose-specific lectins (Con A, PSL) as inductors caused the increase, while application of other carbohydrate-specific lectins caused the decrease of luminol-dependent chemiluminescence in neutrophilic granulocyte suspension after the irradiation. As a result of direct laser effect on the blood cells some portion of the less resistant cells were eliminated from the blood flow, i.e. "rejuvenation" of the neutrophilic granulocyte population in the cells takes place.
