[Microscopic structure of the mesenteric lymph nodes of monkeys].
The structure and cytoarchitectonics of mesenterial lymph nodes were studied in thin histological sections by different methods. Under study were 5 rhesus monkeys and 3 hamadryas baboons. The square surface of different structural elements of the nodes (the cortical and medullary substances, follicles, the connective tissue framework, sinuses) occupied by them in sections was calculated and the amount of cellular elements was determined (%). Comparison of the data obtained in rhesus monkeys and baboons speaks of certain species-specific features of the organs under study. The morphological picture of lymph node sections in baboons (as compared with rhesus monkeys) might suggest earlier ageing of nodes in baboons.
