title: [Vascular-neurocytic interrelations in the ganglionic layer of the dog retina exposed to gravitational overloading].
abstract: By means of anatomical and histological methods and a morphometric analysis, microcirculatory vessels of the reticular ganglionary layer in the dog eye were studied within Scharrer's zone with special reference to the reciprocal arrangement of the vessels and opticoganglionary cells under normal conditions and at overloadings (9 units for 10 min) applied in the direction head--pelvis (I series) and pelvis--head (II series). It was stated that immediately after the overloading in the direction head--pelvis the microcirculatory vessels grew narrow and the area of the vascular-neurocytic contacts decreased. At the overloading applied in the direction pelvis--head, the diameter of the vascular-neurocytic contacts sharply increased. In both series of the experiment the vessels became deformed and twisted and the vascular wall permeability was disturbed.
