[Structure of the endotheliocytes of cerebral vessels of aquatic mammals].
By means of scanning microscopy the relief of luminal surface of endotheliocytes, lining microvessels of various parts of the brain in the Pusa sibirica, Phoca vitulina and Delphinapterus leucas have been studied. Specialized formations of the cellular surface--various processes, projections, toruli have been revealed; their character in various parts of the brain in diving animals is determined by the blood stream conditions and their different sensitivity to oxygen deficiency during diving. The peculiarities, revealed in the structure of the cerebral vessels intima, are considered as one manifestations of the adaptive properties in the organism of diving animals, which had been developed in them during the process of a long evolution, while they adapted to the aquatic environment.
