The authors studied the parameters of the central and cerebral hemodynamics in 66 males aged 38-58 years who were treated at a health resort for initial manifestations of cerebral circulation insufficiency (CCI). A test with graded exercise (GE) revealed in all patients an increase in the total peripheral vascular resistance (TPVR) which was the greatest in cases of initial manifestations of CCI due to borderline arterial hypertension (AH). In the period of recovery and following the nitroglycerin test the TPVR returned to the initial level in patients with AH and vegetovascular dystonia whereas there was no such decrease in patients with initial cerebral atherosclerosis. Already at the 1st minute of the recovery period following GE patients with atherosclerosis (A) and essential hypertension (EH) presented a considerable increase in the arterial tone (AT) which remained stable even after 10 min of rest. These changes in AT indicated a decrease in the adaptational possibilities of the cerebral hemodynamics and simultaneously made it possible to differentiate them from vegetovascular dystonia when AT increased insignificantly only during the first min after GE and then rapidly returned to the initial level and diminished even more during the nitroglycerin test. The proposed method of comprehensive examination of parameters of the central and cerebral hemodynamics when combined with neuropsychological findings makes it possible not only to improve the diagnosis of diseases responsible for initial manifestations of CCI but also to considerably increase the objectivity of the assessment of the sanatorium treatment.

The examination of the cardio-and hemodynamics in 22 patients with neurocirculatory dystonia of the hypertonic type and in 50 patients with stable hypertension showed that in the first group patients the systolic pressure in the pulmonary artery was increased due to hyperactivity whereas in individuals with stable hypertension it did not exceed normal values. A high load on the left ventricle in patients with high hypertension serves as an inotropic factor delaying the decompensation of the left ventricle.

The authors describe a new psychophysiological test based on the use of commercially available television apparatuses and aimed at determining the efficiency of information processing. The use of the test in 346 people has demonstrated its acceptability for building up psychoemotional tension and detecting the hypertensive hemodynamic response. The analysis of the results of the testing conducted in normal subjects and cardiovascular patients has permitted the selection of the most informative criteria of the test. These include the coefficient of information processing, and also the increment and time-course of the blood pressure. This standardized psychophysiological test may be employed in the diagnosis of the early stages of arterial hypertension and neurocirculatory dystonia.

Investigations were carried out at rest and after physical exercise (50 and 75% from maximum) with pressor Fl-alpha and F2 alpha and depressor (A, E) fraction of prostaglandins (PG) in 10 healthy individuals, in 10 patients with neurocirculatory dystoniaa with hypertension and in 10 patients with neurocirculatory dystonia with hypotension. In patients with hypertension at rest as compared to the healthy individuals there was increase of content of pressor and decrease of depressor fractions of PG, in patients with hypotension changes in PG were of the reverse type. In adaptation to physical load at different stage of load levels definite trends in changes in the PG content have been recorded, close to such changes in the healthy subjects and patients with hypotension, and a reverse trend in persons with hypertension.

Clinical and physiological examinations of 76 women in the postmenopause revealed in 64 of them the typical form of the climacteric syndrome, characterized by not only typical symptoms ("flushes", increased exudation, headaches, etc.), but also by various emotional vegetative disturbances detected at profound clinical neurological examination of the autonomic nervous system and the emotional sphere. Individual hormone therapy was associated with an appreciable alleviation of all psychovegetative disorders: "flushes", exudation, irritability, arterial hypertension, severity of vegetative dystonia, hysterical stigmata.

A 50-year-old man with a history of hypertension developed right hemiparesis in February, 1985. Four years later, he noted tremor and involuntary extension of the neck (retrocollis) which was aggravated by walking or emotional stimuli. In addition to retrocollis, which was most pronounced upon turning the head to the left or backward, there also was upward deviation of the eyes (oculogyric crisis) and contraction of the left orbicularis oculi muscle. Magnetic resonance imaging study revealed one small old hematoma in the left posterior putamen and two in the right lenticular nucleus (one in the posterior putamen and the other in the globus pallidus). The findings in this case and in other reported cases of symptomatic retrocollis suggest that bilateral lesions of the putamen are associated with this type of focal dystonia.

Cytochemical analysis was used to compare the activities of hyaloplasmatic and mitochondrial glycerophosphate dehydrogenase, and succinate dehydrogenase in lymphocytes of peripheral blood taken from 14 aviators with the diagnose of hypertonic neurocirculatory dystonia, and 18 healthy aviators. Significantly higher activity of these enzymes in patients is assumed to signify intensification of metabolism and cellular respiration bearing the forced adaptive character. On this evidence, an attempt is made to interpret earlier discovered changes in the immunobiochemical status of these patients and plausible mechanisms of progressive arterial hypertension are hypothesized. Emphasis is laid on the necessity to direct secondary preventive measures at the early phases of hypertension not only on reduction of the vascular tone and correction of the immunobiochemical status but on building-up of cell's functional reserves.

A new method of individual determination of sympathoadrenal activity (SAA) uses the parameter of beta-adrenoreception in cell membranes (beta-ARM) based on the erythrocyte model. Correlation of an individual reference beta-ARM value with specific features of hypertension states, and CVS responses to psychoemotional stress was studied. Described are the method, and normal distribution of individual beta-ARM values in healthy flyers, aviation students, non-flyers, and aviators with diagnosed the neurocirculatory dystonia of hypertensive type and patients with the hypertonic disease of 2nd stage (the overall numbers of subjects = 221). Another group of healthy subjects and patients with the hypertonic disease of 1st stage and different reference beta-ARM values (n = 39) participated in determination of HR and BP levels during the verbal count test. On the evidence of individual beta-ARM distribution in the test groups, the upper limit of the beta-ARM physiological norm (16.0 arbitrary units) was suggested to be a critical parameter in diagnosis of a hyperadrenergic state. Analysis of hemodynamics and the quality of verbal count during performance of a psychoemotional test by subjects with varying reference beta-ARM values revealed hyperreactive cardiovascular systems in and less successful fulfillment of the count test by subjects with high beta-ARM.

Among cardiovascular diseases registered in the Chernobyl wreckers neurocirculatory dystonia and hypertension occur most frequently. Combined treatment including electric sleep, iodinebromine baths, therapeutic exercise, massage relieves clinical symptoms, promotes positive rearrangement of hemodynamics, a decrease in myocardial hyperkinesis and vegetative dysfunction, an increase in cardiovascular reserves, correction of hypersympathicotonia and immune disorders.

Clinical-experimental basis of the possibility of application of the method of indirect rheography of head (IRH) in wide clinical practice was presented. Estimation of the results reproduction and accuracy of the method was performed too. 40 healthy individuals of both sexes at the age of 18-50 and 102 patients with spinal osteochondrosis, arterial hypertension and neurocirculatory dystonia were examined. It was determined that IRH provided 93% of results reproduction and its precision was 90% and higher in comparison with ultrasound method. It was established that head circulation was 750-1200 ml/min or 12-24% of cardiac output in healthy individuals. The results of the study of head blood circulation in some groups of patients were also discussed.
