[The structure of the lymph nodes sequentially located along the lymph flow].

Special features of the construction of more centrally disposed lumbar lymph nodes allow a greater velocity of lymph flow through them to be suggested. In lumbar nodes the states of immune reaction such as lymphocytic hyperplasia and proliferation of the reticular cells as well as degeneration of the connective tissue after the action of harmful factors are met more often than in the peripheral nodes since they have more vast basin of the lymph collection. Specificities of the cellular composition give grounds to suggest a greater strain of immune reactions in the peripheral nodes especially those draining the internal and somatic organs simultaneously.

[Regional features of the cellular composition of different zones of lymph nodes in the adult human].

The amount of plasma cells is connected with intensity of humoral immunological reactions. In people died an accidental death, the amount of immature plasma cells is the least in the axillary and the greatest--in the mesenteric nodes, especially in the thymus-independent zone. The amount of lymphoblasts and large lymphocytes, reflecting intensity of the humoral and cellular immune reactions, is also the greatest in the mesenteric lymph nodes, both in the thymus-dependent and in the thymus-independent zone. In all probability, the intensity of the immunological processes is minimal in the axillary, it is middle in the iliac and cervical and it is maximal in the mesenteric lymph nodes. In each case it is probably connected with peculiarities of antigenic composition of the lymph inflow. The mesenteric lymph nodes are on the way of the foreign protein getting into the intestine. This is evidently reflected by the highest content of immature plasma cells, lymphoblasts and large lymphocytes in them.

[Regional characteristics of the structure and involutional changes in the axillary, cervical, iliac and mesenteric lymph nodes in adults].

A morphometrical and cytological investigation of the lymph nodes has been performed including somatic (axillary), cavitary (mesenteric) and intermediate nodes that get their lymph both from the somatic and from the visceral organs--nodes of the neck and pelvis. Regional and individual peculiarities of the lymph nodes construction (degree of development compartmentalization of the cortical lymphatic substance, follicular density unit, architectonics and the trabecular apparatus maturation, sinus capacity) can be characterized within the limits of three morphofunctional types: compact, fragmented and focal. The human axillary lymph nodes (taking into account certain individual peculiarities) have their structural organization within the interval the compact--fragmented types. The structural organization of the mesenteric nodes corresponds to the interval the fragmented--focal types. The construction of the common iliac nodes individually varies within the interval the fragmented--focal types. The inferior deep cervical lymph nodes are mainly of the fragmented type. An essential part of the lymph nodes in a mature person has immuno-reactive or involutive changes. In the iliac and cervical nodes, hyperplasia of the lymphoid tissue, especially in the medullary cords, is observed more often than in the somatic and the cavitary nodes. Cellular composition of the human mesenteric and cervical lymph nodes is more variable than in the axillary and iliac nodes. Evidently, this reflects the fact that the former group gets a more antigen-saturated lymph than the axillary and iliac nodes.
