[The reaction of somatic lymph nodes to experimental exposure to sulfide baths]

Influence of strong sulfide baths of the sanatorium "Talgi" to the popliteal and superficial inguinal lymph nodes (LN) has been studied in 35 rats (140-150 g of body mass) and 15 animals have been used as the control. The slices are stained with hematoxyli-eosin, after van Gieson, Romanovsky-Giemsa, Kurnik and silver nitrate impregnation after Foot. The section area of the LN decreases, but amount of lymphoid nodules increases (especially in deep layers of the cortex). In the germinative centers amount of middle lymphocytes and mitoses becomes larger. In the internodular zones of the popliteal nodes amount of macrophages and eosinophiles enlarges significantly, and in the inguinal-amount of mast cells and eosinophiles. In the medullary sinuses amount of macrophages declines. In the medullary cords amount of immature plasma cells and blasts increases, while amount of mature cells decreases.
