[Study of nitroblue tetrazolium reduction by granulocytes in workers handling x-ray equipment].

In 44 persons (25 women and 15 men), workers handling X-ray equipment in X-ray laboratories the ability was studied of nitroblue tetrazolium (NBT) reduction by neutrophils. The obtained results were compared with a control group. Besides that subgroups were isolated taking into account the sex of the studied subjects and duration of their work with X-ray equipment (over five years and below five years). In the workers handling X-ray equipment and in the isolated subgroups of women and men, the index of spontaneous NBT reduction turned out to be statistically significantly higher than that in the control group. In the group of studied workers the index of latex-stimulated NBT reduction was statistically significantly lower than that in the control group. Taking into account the duration of work with X-ray equipment in the subgroups of women and men working for over five years, the lowest index of phagocytes was noted. On the basis of the obtained results the following conclusions were formulated: 1. In workers handling X-ray equipment disturbances occur of peripheral blood neutrophil metabolism assessed in the NBT test. 2. Neutrophil phagocytic activity is weakened in persons working over five years with X-ray equipment.
