[The intercellular connection of axons-capillaries in the light of genetically determined resistance to emotional stress].

Genetic factor is one of the main factors of systemic organization of animal resistance to emotional stress. This notion served as a basis for comparing ultrastructural specific of connections between nervous and vascular systems in catecholamine-synthesizing areas of different lines of Wistar and August rats. Quantitative difference has been observed in the structure of cell junctions. This difference may determine different level of adaptive reactions of animals to stress.
