RESUMO
Morphological changes of all links of the terminal vascular bed during acute hypoxic hypoxia were studied in experiment and in postmortem material. A complex of methods was used including microdissection, injection with India ink - gelatin, clearing, silver nitrate impregnation after V. V. Kuprijanov, staining after Van Gieson and with hematoxylin-eosin, biomicroscopy and reoencephalography. Signs of desorganization of the vascular bed were revealed which manifested themselves as changes in microangioarchitectonics and diameters of vascular lumens, increased permiability of their walls with saturation of them with white and escape of its forming elements of the blood outside the limits of the vessels, as well as in destruction of the aggregate state of the blood. It considerably enlarges our knowledge of the state and changes in the vascular bed during hypoxic hypoxia.
