[Distribution and morphologic characteristics of lymphoid cells in the canine popliteal lymph nodes in their normal state and under antigen effect].
By means of morphometry, light and electron microscopy methods peculiarities in distribution of small, middle and large lymphocytes, as well as plasmocytes in various zones of the popliteal lymph nodes have been studied in normal and in dynamics up to one year after subcutaneous injection of BCG vaccine into the left hind paw. The antigen produces certain changes in density and morphological parameters of lymphoid cells both in the regional and in the contralateral lymph nodes. For them 3 periods are specific. During the first 3 days they are not antigen-dependent (stipulated by the stress reaction), during 7-24 days antigen-dependent processes of proliferation and differentiation of lymphocytes get into action. In 3 months a new wave of the immune response is observed.
