[The effect of excessive artificial UV radiation on the measurement of blood parameters and phagocytosis in calves].
5 calves of an age of 33 days were exposed to UV-light (280-320 nm) for a time of 12 hours. The mean dose of radiation was 179 x 10(-10) J/h x m-2. The results show slight influences of overdosed radiation on hemoglobin content of the blood, from 105.1 g/l to 102.6 g/l. The mean content of hemoglobin in erythrocytes decreased: 364 g/l to 347 g/l. The total leucocytes decreased from 7.74 x 10(9)/1 to 7.08 x 10(9)/1 after exposition of 5 hours. The exposition increased lymphocytes (55.6% to 66.0%) and decreased neutrophils (43.6% to 33.8%). The relationship of lymphocytes to neutrophils extended even after radiation time of only 5 hours from 1.45 to 2.04. The phagocytotic activity increased after 5 hours of exposition. To the end of exposition (60 hours after observation) a decrease was observed. A correlation between doses of radiation and hematological changes was found after 12 hours of radiation in lymphocyte counts (r = 0.878) and neutrophil counts (r = -0.824) as well as in the relation of lymphocytes to neutrophils counts (r = 0.941) and in the index of phagocytosis (r = 0.804).
