[The density of the lymphatic bed of the small intestine mucosa].
The investigation was performed on 35 corpses of men, 8 corpses of cats, 7--of pigs and 5--of horses. The following methods were used: polychrome injection of arteries, veins, lymph capillaries and vessels, macro-microdissection, staining after van Gieson and with hematoxylin-eosin, impregnation with 0,25--1% solution of silver nitrate, dehydration and clearing, calculation of thickness of loops per 1 mm2 and their depth  by means of ocular micrometer. The lymphatic bed of the serous membrane was established to be better developed in representatives of carnivora (cats) and omnivora (pigs), than in herbinorous horses. The monolauer capillary lymphatic network was revealed in horses while in carnivora (cats) and omnivora (pigs) the network of lymph capillaries and the bundle of lymphatic vessels were revealed. The lymphatic bed of the serous membrane was sufficiently developed in young animals. Local distinctions were established along the length and width of the small intestine, which might be explained by different functions of different portions of the gut.
