[Lymphatic bed of the colon in newborn infants]

The material to be studied was obtained from 57 corpses of newborns died in asphyxia. The colonic lymphatic bed is not completely formed by the time of birth; that is demonstrated by the following signs: lack of marked networks in the serous tunic and capillaries in the muscular tunic, incomplete development of networks around the greater part of lymphoid follicles in the submucous tela, presence of unclosed loops of the lymphatic capillaries in all the layers of the organ's wall. A great number of blind processes (growing capillaries) and valvular germs in the lymphatic vessels demonstrated further development of the colonic lymphatic bed in newborns.
