[The role of adrenergic structures in the control of cerebral circulation].

A study of the cerebral blood flow carried out by the thermoelectric method demonstrated that stimulation of the cervical sympathetic nerve led to marked changes in the cerebral blood supply. The blood flow changes were two-stage in character: an initial slight increase changed to a decrease below the initial level. Pharmacological analysis with the use of alpha- and beta-adrenoblockers showed a constrictor reaction of the cerebral vessels to be caused by excitation of the alpha-adrenoreactive structures, and the dilatator reaction - by the beta-adrenoreactive structures. An opinion is put forward on a possible mechanism of these changes.

Physiological mechanisms of the "arousal response" in animals in a state of hypobiosis.

In a state of hypobiosis in white rats it was found that the previously described [4, 6] "arousal response" is characterized by a flareup of motor activity with a definite coordinated structure of the motor acts in response to a change in the animal's posture. Repeated reproduction of this response leads to a rapid summation of the electromyographic activity and a rise in the temperature. In experiments on heterothermic animals these responses are even more pronounced and are accompanied by a restoration of the original body posture and substantial temperature rise. Such an effective process of heat formation in the bodies of heterothermic animals during the "arousal response" may be associated with the mechanism of "special" awakening under conditions of reduced activity.

Role of adrenergic structures in functional control over the cerebral circulation.

An investigation of the cerebral circulation by the thermoelectric method showed that stimulation of the cervical sympathetic nerve leads to considerable changes in the blood supply to the brain. The changes in blood flow are biphasic in character: An initial small increase is followed by a decrease below the original level. Pharmacological analysis with alpha and beta adreno-blockers showed that the constrictor response of the cerebral vessels is due to excitation of alpha-adrenergic structures and the dilator response to excitation of beta-adrenergic structures. A possible mechanism of these changes is postulated.

[The use of an electrosleep method for restoring the performance capacity and relieving the psychoemotional stress of athletes in cyclic sports].

44 boat-racing sportsmen entered the study which aimed at elucidation of electric sleep action on restoration of muscular performance and relief of psychoemotional stress. The electric sleep procedures were found to stimulate regeneration processes, improve cardiovascular function and myocardial contractility, normalise arterial and capillary tonicity, to potentiate muscular performance and aerobic power of the body.

[The effect of combined transcerebral magnetic and electric impulse therapy on the cerebral and central hemodynamic status of stroke patients in the early rehabilitation period].

75 clinical cases of acute impairment of cerebral circulation treated with sinusoidal modulated currents in combination with transcerebral magnetic field have been analysed. Functional and clinical findings indicate that the above combination is much more effective than magnetic field and sinusoidal modulated currents alone: 62% against 35% and 33%, respectively.

[The importance of electroencephalographic studies for evaluating the action of physical treatment methods in patients with a neuroendocrine syndrome and disordered menstrual function].

Electroencephalograms of 43 females (mean age 27.3 +/- 5.2 years) were examined for integral power of various EEG rhythms, delta, beta, alpha, beta 1 intervals for occipital, parietal and frontal region, right and left hemispheres. The frequency analysis was made with regard of EEG type. A particular role of the right hemisphere in development of neuroendocrine pathology is discussed.
