Variation of the lecitin-induced chemiluminescence of neutrophilic granulocytes after blood irradiation with He-Ne laser

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 leucotrien B4 and thromboxan B2 increased in the other neutrophils. Application of mannose-specific lectines (Con A, PSL) as inductors caused the increase, while application of other carbohydrate-specific lectines 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
