[Age and local changes in the architectonics of the lymphatic bed of the wall of the jejunum and ileum in normal rabbits].
Age and local changes of the lymphatic bed have been studied in the jejunum and ileum preparations obtained from 100 rabbits. The architectonics of the bed is stated to undergo some age and local changes. In fetuses and two-week-old rabbits, chyle sinuses are narrow and all flow into the capillaries of the tela submucosa. In one-month-old animals, the mucosal capillary network is developing and the chyle sinuses flow into it. In six--ten-month-old rabbits, intestinal bed is already formed, the chyle sinuses are wide. Aged changes are represented by a considerably rarefied networks, decrease in the chyle sinuses caliber, deformation of the sinus, capillary and vessel walls. In the jejunum, unlike the ileum, the chyle sinuses are of larger size and have more complex architectonics in the capillary networks of the mucosa and tela submucosa.
