Abstract

Somatic and visceral lymph nodes (LN) dromedary were investigated by using routine morphological and complex immunohistochemical methods. The purpose of the study was to determine the characteristics of histo-architectonics parenchyma of the lymph nodes in general, individual syntopy cells area and patterns of parenchymal structure of intra-site lymphatic channel.
Macroscopically LN of dromedary is a conglomerate of lobed structure that is formed as a result of partial fusion of separate autonomous units (subunits) of nodes. Depending on character of lympho-dynamics LN of dromedary belongs to the nodes of the classical type in which the afferent lymph to the lymph vessels goes directly into the sinus the edge rather than in the lymph collectors of capsular trabeculae.Intra-site lymphatic channel is a coarse uniform mesh of wide lymph sinuses that divide the lymph node parenchyma into discrete sections. Thus, lymph node parenchyma of dromedary has a discrete (islet) not the zonal character of structure. Subunit of lymphoid parenchyma (islets) consists of a set of typical mammalian cell lymph node areas — units of deep cortex (T-cell zone), lymph nodules (B-cell zone), medullar cords of cortical plateau (on the border with marginal sinus). In their structure and syntopy the islets of the lymph nodes of parenchyma in dromedaries are analogues of lymph nodes lobules (compartments) in other mammalian species, but with an unique multi-level nature of localization. Lymph nodules in the parenchyma of the lymph nodes in dromedaries are characterized by cross-cutting nature and are located in the peripheral parts of deep cortex.
