[The comparative effectiveness of different psychological methods for treating patients with a labile course of hypertension (based on international research data)].

Examination of 110 patients with essential hypertension (EH) carried out in the USSR and GDR revealed, by the end of the observation period (one year), a significant lowering and normalization of arterial pressure at rest and a certain reduction of the intensity of the hypertensive response to psychoemotional stress influences in the presence of psychological relaxation therapy (PRT). The survey made it possible to try the designed methods for PRT in both countries and demonstrated that the intensity of the hypotensive action of the methods appeared comparable in different populations of patients suffering from essential hypertension. The intensity of the hypotensive action of PRT correlated with the level of arterial pressure before treatment, with the age of EH patients, and with their psychological characteristics.

[Psychophysiological correlations and reactivity of patients with hypertension].

A clinical psychophysiologic and psychologic assessment was made twice, at 12 months' interval, in 203 patients with essential hypertension (EH). In addition to aggravated heredity, EH patients showing more marked BP increment under emotional stress had higher level of anxiety, rigidity and interpersonal conflicts. Different cardiovascular response to various emotive stressors was dependent on psychological characteristics of EH patients.

Psychophysiological interrelations and reactivity characteristics in hypertensives.

Two hundred three patients with essential hypertension (20- to 55-year-old men) were examined initially and at the end of a 1-year follow-up. Clinical, psychological, and psychophysiological methods were used. In the psychophysiological assessment, systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate, and respiratory rate were recorded at rest and during various emotional stressors.

[Cortical and medullary circulation of the kidneys in pressor and depressor sinocarotid reflexes].

An experimental study in 12 anesthesized rabbits has demonstrated, by means of the hydrogen clearance test, that carotid sinus baroreceptors participate in the control of both the cortical (CF) and the medullary (MF) renal flow. The direction and magnitude of CF and MF changes in case of sinocarotid reflexes are determined by the relationships between extrarenal nervous effects, systemic blood pressure (BP) and self-regulative response of the cortex and the medulla. Arterial hypotension during depressor sinocarotid reflexes is accompanied by decreased CF and MF, while blood pressure stabilization increases CF and MF in these conditions.
