The effect of low dose-rate a-radiation on cellular contentof the chronic inflammatory focus

Abstract
On the model of chronic aseptic carrageenan-induced inflam-
mation in rats it is shown that low dose-rate y-radiation of
small dose (0.1 Gy) leads to the increase of fibroblast and
macrophage proliferation in the inflammatory focus, and pro-
duces considerable decrease of lymphocyte emigration at all
investigated radiation doses. Obtained data on stimulation of
proliferation in the inflammatory focus with possible accumu-
lation of DNA errors at depressed immunological supervision
by lymphocytes can indirectly point to probability of oncog-
enous potential increase in the chronic inflammatory focus at
low dose-rate y-irradiation.
