[Comparative characteristics of cellular composition of the lymphoid structure of various regions of the human intestine in early childhood].
Using microscopic methods and statistic analysis lymphoid structures of large and small intestine walls and appendix were studied in 4-7 years children. The highest cell reproductive activity was detected in duodenal walls being slightly lower in appendix and group lymphoid vessels. The highest ratio of plasma cells was found in duodenum, ileal lymphoid patches and cecum, where the index was 7-fold higher than index of appendix and ileum. Lamina propria of intestinal mucosa is characterized by small fraction of mitotically dividing cells and undifferentiated cell forms, especially in cecum walls. However, the latter shows the greatest percentage of plasma cells.
