[Function of the microcirculatory system during the long-term regression of the early stages of atherogenesis].

Lipid metabolism, intestinal mesentery microcirculatory bed (MCB) and erythrocyte (E) morphology in arterial and venous blood were studied in rabbits with experimental atherosclerosis (the model of N. N. Anichkov) and its spontaneous regression. The interrelation was determined between lipid metabolism (LM), MCB structural and functional disorders and anomalous E form appearance, and to a lesser extent the atheromatosis of the aorta. Microcirculatory (MC) disorders disappeared 12 months later in the regression of the early stages of atherogenesis (after 2 months of diet). The generalized character of MC disorders in LM suggests the existence of a trend towards MC reconstitution in prolonged regression in different organs and tissues. Thus, LM correction at the early stages of the pathological process can be accompanied by the disappearance of MC disorders, which seems important for the prevention of atherosclerosis.
