[Construction and cellular composition of the hepatic lymph nodes of monkeys]

Construction and cellular composition (cortical plateau, follicles and medullary cords) of the hepatic lymph nodes have been studied in 4 species of healthy mature Macaque (brown, pig-tailed, and rhesus). Histological sections made at the hilus of the lymph node and studied by means of Glagolev's morphometric grid in S. B. Stefanov's modification have demonstrated that every structural component possesses a peculiar cellular composition, i. e. has its own cytological profile. Lymphocytes make the predominant cellular form, with small and middle ones dominating in all components of the node. In follicles with light centers and in medullary cords a considerable mitotic activity, high contents of lymphoblasts and plasmocytes (in the medullary cords) are noted.
