[The regional morphological characteristics of the endothelium of the human thoracic aorta in perfusion fixation].
The ultramicroscopic organization and the endotheliocyte surface relief in ventral portions of the thoracic part of human aorta and in zones of division of blood flow were studied under conditions of early post mortem examinations and perfusion fixation of corpses of 14 humans dead from accidental causes. Zones of entrance into the intercostal aortas are compared with the straight portions of the aorta and are found to be characterized, as compared with the latters, by polymorphism of the endothelium, higher adhesiveness of its surface to blood elements, as well as by the presence of intravitally de-endothelialized portions localized on the ridge of the intimal valve.
