[Anatomy and topography of adult human mesenteric lymph nodes].

Topography, number and age changes of the mesenteric lymph nodes in the small intestine have been studied in 40 corpses of both sex at the age of 21-90 years. The mesenteric lymph nodes, their afferent and deferent vessels have been revealed by the method of intersticial injection of coloured masses into the small intestinal wall, as well as by a direct injection of the lymph nodes studied in the mesentery. Variability in the total number of the mesenteric lymph nodes has been demonstrated; topographic borders of separate groups of the mesenteric lymph nodes have been stated; topography of the lymph nodes as regards the mesenteric blood vessels has been described. Quantitative changes (total and group) in the mesenteric lymph nodes with age in grown-up persons have been demonstrated.
