The effects of acute joint exposure to radiation and certain pesticides on the peripheric blood in rats

The effect of joint external γ-radiation and some pesticides on the peripheric blood is studied. Lindane, trichlorfon and tetramethylthiuram disulfide are used as toxic chemicals. It is shown that the combined effect has caused, like radiation, stable leukopenia, but less expressed than the effect of gamma radiation. It is especially obvious in the case of combining ionizing radiation and TMTD when the number of leukocytes averaged by 25% more than in the case of injury by radiation alone. Lymphocytes are most sensitive blood cell elements earily responsing to radiation and chemical organism injuries, both qualitatively and quantitatively. The results of analyzing the dynamics of the most qualitative and quantitative paramaters of leukocytes permit to state the summation of mutual effects of factors of radiation and chemical nature
