  • Title: [Ultrastructure of the lymph nodes of dogs under prolonged external gamma irradiation].
    Author: Shikhodyrov VV, Bespalova LA, Romanov VS.
    Journal: Kosm Biol Aviakosm Med; 1979; 13(4):62-6. PubMed ID: 459403.
    Abstract:
    The purpose of the present investigation was electron microscopy study of lymph nodes of dogs exposed to chronic gamma-irradiation during 6 years (with a total dose of 125 rad/year). The exposure induced changes in the cell composition of the paracortical regions due to a decrease of the count of small lymphocytes and a predominant increase of young blast cells with an altered ultrastructure. Chronic gamma-irradiation led to an increase of the number of plasma cells and emergence of intermediate cell forms due to "plasmatization" of lymphocytes and reticular cells.
