[The characteristics of the bone marrow stromal elements in the participants in the cleanup of the aftermath of the accident at the Chernobyl Atomic Electric Power Station in the long term].

Histologic features were studied of bone marrow biopsies in 25 individuals who took part in the elimination of the aftermath of the Chernobyl accident and who had received a radiation dose of at least 1 Gy. Particular features of the studied trepanobiopsies included dysplasia of granulocytes, hypocellular bone marrow, circulatory disorders and sinusoidal distortion, edematization of stromal elements, substitution of fibroreticular tissue for hemopoietic one. No relationship was established between the changes revealed and radiation dose.
