[A respiratory syndrome in patients with neurocirculatory dystonia]. / Respiratornyi sindrom u bol'nykh neirotsirkuliatornoi distoniei.

The purpose of the work was to evaluate the compensatory and adaptive possibilities of oxygen transport systems in moderate hypoxic hypoxia to define the sensitivity to hypoxia of patients suffering from neurocirculatory dystonia (NCD) with the respiratory syndrome and to elaborate training therapy methods. 40 patients suffering from cardial NCD were examined. Of these, 23 complained of dyspnea. The general hypoxemic test (GHT) was used; parameters of external respiration, hemodynamics, gas composition of blood, and the content of oxidation substrates were examined. Analysis of the clinical picture of respiratory disorders in patients with cardial NCD revealed the differences in their nature. In addition to psychogenic factors of dyspnea, of importance was a decrease in the compensatory and adaptive possibilities of the body as regards hypoxia, which occurs in mental, physical stress, changes in meteorological conditions, in closed premises, and in vegetovascular crises.

[Characteristics of peripheral circulation and tissue metabolism in patients with functional venous hypertension and various forms of arterial hypertension]. / Osobennosti perifericheskogo krovoobrashcheniia i tkanevogo metabolizma u bol'nykh s funktsional'noi venoznoi gipertenziei i razlichnymi formami arterial'noi gipertenzii.

Venous-occlusion plethysmography was used to examine peripheral hemodynamics. Oxygen transport, serum lactate and pyruvate levels, and ++intra-tissue pressure in the forearm muscles were studied. A total hypoxemic test was employed as a functional tool. The findings suggest that the changes in venous blood flow and tone, transcapillary and tissue metabolism are unidirectional in functional venous hypertension, borderline hypertension, and hypertensive disease, which should be taken into account in the diagnosis and treatment.
