[Hemodynamic restructuring of the gastric macro- and microcirculatory bed in disordered circulation]

Species-specific peculiarities of extra- and intraorganic gastric blood vessels in some representatives of carnivores, herbivores, omnivores (220 animals) have been studied. Sources of the gastric blood supply have been defined in dogs, foxes, cats, rabbits, guinea-pigs, white rats, pigs; intraorganic distribution of blood vessels and local peculiarities of the microcirculatory bed have been studied in the normal organ. Structural bases during restorative processes of the gastric circulation after subtotal and partial devascularization have been revealed; collateral pathways, plastic properties of vessels having various diameters have been described in detales. A great attention has been paid to rearrangement of some microcirculatory links, to certain capacity changes, with special reference to dynamics of morphological indices.
