[Status of the blood system and nonspecific anti-infection defense during external irradiation of rats with a low-energy infrared laser]. / Sostoianie sistemy srovi i nespetsificheskoi protivoinfektionnoi zashchity pri vneshnem obluchenii krys nizkoénergeticheskim infrakrasnym lazerom.

The epigastrium was irradiated by low-energy infrared Skalyar laser in intact noninbred rats. The energy exposure at 5 and 20 MW was found to be accompanied by the development of leukocytosis at the expense of all types of leukocytes, the extensiveness of early phases of polynuclear phagocytic activity, increases in neutrophilic redox processes and complement titers during 7 days of the experiment. The count of red blood cells, the levels of hemoglobin, and lysozyme enzymatic activity were decreased, hematocrit remained in the normal ranges. Increasing the exposure rate up to 40 MW retarded the responses of defensive mechanisms or resulted in their baseline suppression.
