| Abstract: | According to a standartized technique, a morphometrical investigation of the stomach tunica mucosa (STM) has been performed in 11 practically healthy persons and 69 animals representing 4 orders and 9 femilies of Mammalia. In Mammalia, together with a principle similarity in the stomach microscopical structure, there is a great variety of main morphometrical parameters of the STM. The whole complex of these parameters is species-specific. It is determined by the systemic position of the given species and reflects the filogenetically-dependent nutritional specialization. The main mechanism and the filogenetically-dependent characteristic of adaptation to protein nutrition is an increase in the number of the main, but not the parietal glandulocytes. The dependence revealed gives a new interpretation to the problem concerning the relation between the structure and function of the STM in animals with different nutrition type; this dependence makes it possible to consider the problem of ulcerogenesis and its biological prerequisites in the man from new positions. |
