title: [The angioarchetectonics of the small intestinal mucosa in laboratory animals].
abstract: The authors examined microvascularization of the mucosa of the colon by administration of the contrast massindian inkgelatin into the blood stream. In guinea pig, rat, dog and cat the structure and angioarchitectonics of the colon mucosa showed principle similarity- in the submucous layer there was vascular plexus, but in the glandular layer - a spatial capillary net. In carnivourous animals (dog, cat) the capillary net was larger and more complex than in the animals eating plant food (guinea pig) and in it there were two areasperiglandular and subepithelial with specific angioarchitectonics. Animals, receiving two kind of food (white rat), showed similarity with both groups of animals. In the colon of the rabbit two regions with various structure and angioarchitectonics were separated. The mucosa in the terminal part of the colon and rectum was studded with glands and its vascularization showed similarity with that of the aforementioned animals. In the remaining part of the rabbit colon the mucosa had "papillas" penetrated by glands. Their vascularization was accomplished by vascular, formations, resembling partly those, described by other authors in the small intestines.
