[Function and reactivity of the microvascular bed in human neuroses].
By contact microscopy the state and reactivity of the capillary bed (capillaries of the cheek mucosa) were studied in neurotic patients with different levels of arterial pressure (AP). It has been shown that at constant AP capillariscopic parameters (diameter, length and number of capillaries in the visual field) are relatively stable. Neuroses with hypertension are characterized by uneven (more expressed in arterioles) contraction of the capillaries, accelerated development and greater duration of reactions to the mental stress and applications of adrenaline and noradrenaline solutions in comparison with healthy persons. In hypotension, uniform capillaries contraction and slower development of the above reactions are observed.
