[Macroscopic structure of the inferior tracheobronchial lymph nodes of papio hamadryas baboons].

The investigation has been performed in 58 corpses of practically healthy Papio hamadryas beginning from birth up to 20 years of age. Age changeability is manifested as an increasing size and number of the nodes in the group, as the connective tissue framework development (thickening of the capsule and increasing number of trabecules) as well as increasing complexity in the structure of the cortical and medullary substance, by the time of puberty they reach their optimal correlation. Seasonal changes are manifested as fluctuations of absolute size of the nodes and relative areas of their structural components. Sexual changeability, connected with a pronounced dimorphism in the animals studied, is manifested in number and size of the nodes of the given regional group and in a developmental degree of their structural components.
