[Microcirculatory disorders in patients with cerebrovascular pathology].

The microvascular network of the labial mucosa and the nail bed, as well as the rheological properties of the blood were examined in 132 patients with various forms of cerebral circulation disorders. It was shown that the patients with the cerebrovascular pathology had organic changes of the capillaries. At the same time a hyperreactivity of the microvessels was observed. This hyperreactivity was more marked in patients with initial forms of the cerebrovascular disturbances. In the patients examined an increased permeability of te capillaries for protein and water was revealed: this increase was found to correlate with the disease gravity. Along with the vascular changes the patients also showed disturbances of the blood rheological properties. These disturbances manifested in an increased viscosity of the blood (especially at low shear speeds) and an increased aggregation of erythrocytes. It was also found that not only the erythrocyte aggregation, but also the strength of the aggregates formed were increased: this correlated well with the disease gravity.

[Memory disorders in patients with saccular aneurysms of the internal carotid arteries].

Neuropsychological analysis of disorders of memory in patients with sacculated aneurysms of the internal carotid arteries, 14 of whom were examined in the immediate and 30 in the remote periods after the hemorrhage, showed that the side of the lesion may be judged by the character of these disorders. The disorders of memory were of a modally-specific character and emerged in the link of direct reproduction in aneurysms of the right internal carotid artery and in the link of delayed (under conditions of interference) reproduction in aneurysms of the left internal carotid artery. The general cerebral signs in the acute stage of subarachnoid hemorrhage are also manifested specifically in the structure of the memory defect.
