title: [The age-dependent peculiarities of quolitative analysis of intestinal villi morphogenesis].
abstract: The aim of our investigation was to study morphogenesis of microcirculatory bed of small intestine villi in rats. The research was conducted on 48 (male and female) 1 day, 7 day, and 17 days old white rats by using scanning electron microscope and metrical parameters of the villi components. Measurement of the microvessels profile area in the shear plane on different levels of fiber is changed. Before feeding of the animals it is decreasing and after feeding it is increasing. We came to the conclusion, that microvessels are in all parts of villi, especially in new born before feeding and in all ages too. And there is a great tendency of lowering this index in all ages from top to basis (In 1 day animals 4 times; in animals 7 day 3 times; and in 17 day old animals 2 times.
