Influence of Infrared Laser on Lifespan and Counts of Some Populations of leucocytes in Gamma-irradiated Mice

Popis výsledku v původním jazyce

Background Gamma rays are biologically hazardous type of ionizing radiation. Purpose The purpose of this study was to investigate the influence of 940-nm diode laser on counts of neutrophils, lymphocytes and their subpopulations, and on the lifespan of gamma-irradiated mice. Material and Methods Mice were assigned to groups according to the type(s) of influence and sequence of irradiation: (1) no influence, (2) only gamma radiation (8.7 Gy), (3, 4) only laser (33 or 132 J), (5, 6) combination of laser (33 or 132 J) and gamma radiation, (7, 8) combination of gamma and laser radiation (33 or 132 J). Interval between combination of two types of irradiation was 24-h. Each group was randomly subdivided into 2 subgroups, where lifespan of mice and counts ofneutrophils, lymphocytes and their subpopulations (on 12th day after gamma irradiation) were analysed. Results 940-nm diode laser at 33 J significantly increased lifespan of mice (p<0.05). In the same group, counts of neutrophils, lymphoc
