ABSTRACT: The immobilisation stress seems to suppress the contractile function and the reactivity of the aorta smooth muscle reactivity as the result of augmentation of the NO basal production in endotheliocytes.Fiziologicheskiĭ zhurnal SSSR imeni I. M. Sechenova 01/1996; 82:46.
Article: A P Solodkov; A P Bozhko [The mechanism of the action of low doses of thyroid hormones on the stressor-induced changes in rat vascular tonus]. Fiziol Zh Im I M Sechenova 81, 95 (1995)[show abstract] [hide abstract]
ABSTRACT: Small doses of thyroidine were found to diminish a 6-hr immobilisation-induced decrease of the mean AP and duration of a hypertension response to blockade of NO-synthasa. The thyroidine seems to act on the system of endothelial nitric oxide synthasa.Fiziologicheskiĭ zhurnal SSSR imeni I. M. Sechenova 01/1995; 81:95.
Article: A P Solodkov; A P Bozhko [Changes in the endotheliocyte activity of the coronary vessels under the influence of stress]. Fiziol Zh Im I M Sechenova 80, 65 (1994)[show abstract] [hide abstract]
ABSTRACT: The effect of saponin and blockade of the nitrogen oxide upon the coronary endothelium was found in rats subjected to a 6-hrs stress. The damage of the endothelium and the blockade abolished the stressor-induced increase in the coronary blood flow velocity. The index of autoregulation and the latter's efficiency, however, remained the same. Preliminary administration of L-arginine prevented the effect of NG-monomethyl-L-arginine upon the coronary flow in the isolated hearts of rats subjected to stress. The post-stressor increase in the coronary blood flow seems to be due to an increase in releasing the nitrogen oxide from the coronary vessels' endotheliocytes.Fiziologicheskiĭ zhurnal SSSR imeni I.

Article: A P Solodkov; V I Shebeko; A P Bozhko; Iu Ia Rodionov [The autoregulation of the coronary flow of the isolated heart in rats after saponin damage to the endothelium]. Fiziol Zh Im I M Sechenova 79, 129 (1993)[show abstract] [hide abstract]
ABSTRACT: The damage of the endothelium with saponin completely abolished the autoregulation of the coronary vessels in the Langendorff isolated heart and reduced the volume velocity of the coronary blood flow by 34% at the perfusion pressure 40 mmHg. Indomethacin and verapamil augmented the coronary flow in intact rats. All these agents decreased the distensibility of the coronary vessels by 43-49% on the average. The damage of the endothelium of coronary vessels reduced the maximum reactive hyperemia and, respectively, the coronary vasodilator reserve.Fiziologicheskiĭ zhurnal SSSR imeni I. M.

Article: [The coupling of phosphoinositide metabolism sensitive to ACTH with the adenylate cyclase system in the synaptosomes].[show abstract] [hide abstract]
ABSTRACT: The effect of cAMP on the phosphoinositide metabolism increased by the ACTH, was studied in the rat brain synaptosomes. The data obtained suggest that a coupling of the phosphoinositide metabolism and the adenylate cyclase system occurs under these conditions.Fiziologicheskiĭ zhurnal SSSR imeni I. M.

Article: [The normal distribution of oxygen tension on the surface of the brain radial arterioles and in their surrounding tissues and under normobaric hyperoxia].[show abstract] [hide abstract]
ABSTRACT: The pO2 on the arterioles' wall was shown to depend on the diameter of the vessels under study in rats. In normoxia, the pO2 tissue gradients are small and do not depend on the vessel diameter, whereas in hyperoxia a sharp drop of the tissue pO2 occurs at some distance from the vessel and the dependence of the pO2 on the arteriole diameter can be registered practically in all the sites of measuring. Radical arterioles and adjacent tissues of the brain cortex were shown to be most affected by a high arterial pO2 in hyperoxemia.Fiziologicheskiĭ zhurnal SSSR imeni I. M. Sechenova 12/1992; 78(11):98-103.

ABSTRACT: After 3-hr cooling stress, the activity of the erythrocytes' Na,K-ATPase was decreased by 28.9 per cent in rats, its complete restoration occurring within 24 hours after the stress. Possible reasons and factors inducing a disorder in the enzyme activity under conditions of hypothermia, are discussed.Fiziologicheskiĭ zhurnal SSSR imeni I. M. Sechenova 12/1992; 78(11):119-24.

Article: [The effect of transcranial electrostimulation in an analgesic regimen on somatosympathetic reflexes].[show abstract] [hide abstract]
ABSTRACT: The mechanisms of inhibitory effect of transcranial electrostimulation in analgesic regime on blood pressor nociceptive reflexes were studied in experiments in rabbits and cats. Considerable inhibition of the late (bulbar) somato-sympathetic reflexes and spino-bulbo-spinal somato-somatic reflexes as well was demonstrated. The probable basis of sympatho-inhibition during transcranial electrical stimulation is a reduction of excitatory input to bulbar sympathoexcitatory neurons. It was revealed in experiments with inhibition of sympatho-excitation elicited by temporal brain ischaemia and local electrical stimulation of different bulbar ventrolateral vasomotor zones. The role of periaqueductal gray activated by transcranial electrical stimulation as a source of inhibition and its opioid mechanisms are discussed.Fiziologicheskiĭ zhurnal SSSR imeni I. M. Sechenova 12/1992; 78(11):46-54.
Article: [The characteristics of the correlation of the functional activity, blood supply and structural organization in the sensory-deprived cerebral cortex in rats].[show abstract] [hide abstract]
ABSTRACT: The feature of correlation between functional activity of the brain tissue and structural-functional characteristics of the vascular system after sensory deprivation by the removal of whiskers in newborn animals were studied in nembutal-anaesthetized rats in comparison to the animals under d-tubocurarine with local anesthesia. It has been shown that there are major changes of EP parameters and ECoG in the sensory-deprived brain area and diminution of brain cortex thickness. Changes in the vascular system are mainly structural, what are revealed as disorganization in angioarchitecture of radial arteries. At the same time, differences in the blood circulation intensity are found in d-tubocurarine animals only. The largest volume of the local blood circulation is observed in intact hemisphere of sensory-deprived animal. Thus, it can be concluded that sensory-deprived model is the alternative to the ischemia model. This model can be used in studies of physiology of brain blood circulation, and the "structure-function" correlation, in particular.Fiziologicheskiĭ zhurnal SSSR imeni I. M. Sechenova 12/1992; 78(11):87-97.

ABSTRACT: Single stimuli applied to the suprachiasmatic and supraoptic nuclei of the hypothalamus evoked short-latency hypothalamo-retinal responses which exert influences upon formation of the "a" and "b" waves of the electroretinogram, the changes of the waves being opposite by character. The effects from the suprachiasmatic and supraoptic levels were opposite, too.Fiziologicheskiĭ zhurnal SSSR imeni I. M. Sechenova 12/1992; 78(11):61-71.
Article: [Stress and arterial hypertension].[show abstract] [hide abstract]
ABSTRACT: Subjects with normal arterial pressure, those with bordering values of the AP and patients with arterial hypertension were studied. The AB, heart rate and diuresis changed independently under stress in the first group subjects, whereas these parameters depended on each other to some extent in the "future patients".Fiziologicheskiĭ zhurnal SSSR imeni I.

ABSTRACT: Noradrenergic and GABA-ergic systems were correlated and dominated in the processes of spinal cord segmentary apparatus superactivity compensation. An increase in c-GMP content in the spinal cord suggests an intensification of the activation mechanism. An increase in the c-AMP content may suggest an inhibition of the compensatory intensification of noradrenergic or GABA-ergic mechanisms.Fiziologicheskiĭ zhurnal SSSR imeni I. M. Sechenova 12/1992; 78(11):82-6.
Article: [The spectral characteristics of the effect of central M-cholinolytics on rat behavior under open-field conditions].[show abstract] [hide abstract]
ABSTRACT: Having estimated the rat behaviour in the open-field test, M-cholinolytics were divided into different groups. Haloperidol normalised the disturbance in the behaviour induced by one group M-cholinolytics and had no effect with the other group. The former group seems to have an explicit dopaminergic activity. The groups seem to correspond to different mechanisms of the behavioural activity.Fiziologicheskiĭ zhurnal SSSR imeni I. M. Sechenova 12/1992; 78(11):41-5.
Article: [Changes in the functional activity of the brain stem system that inhibits movement during the development of cataleptiform states].[show abstract] [hide abstract]
ABSTRACT: Electrical stimulation of the n.cuneiformis and medial parabrachial nucleus inducing the inhibition of locomotor behaviour, was performed in cataleptic and non-cataleptic rats. The stimulation of the inhibitory brainstem zones proved to be more effective in cataleptic animals, the state having been induced by a nociceptive stimulus.Fiziologicheskiĭ zhurnal SSSR imeni I. M. Sechenova 12/1992; 78(11):55-60.
Article: [The activation and inhibitory postactivation effects of chemical interoceptive stimulation under normal conditions and in experimental neurosis].[show abstract] [hide abstract]
ABSTRACT: The realisation of hemointeroceptive effects was found to begin with a period of the brain activation. In normal conditions a positive correlation was found between the EEG arousal response and the concentration of mustard administered into the stomach. In experimental neurosis, both regulatory influences of the hemointeroceptive stimulation were decreased.Fiziologicheskiĭ zhurnal SSSR imeni I. M. Sechenova 12/1992; 78(11):72-81.
Article: [Second messengers in the triggering and adaptational-trophic effects of the antidiuretic hormone].[show abstract] [hide abstract]
ABSTRACT: Vasopressin exerts a triggering effect upon the cells of the osmoregulating epithelium as well modulates this effect. The triggering effect is associated with the stimulation of V2-receptors in the frog bladder, whereas the modulating effect is related to the activation of the V1-receptors.Fiziologicheskiĭ zhurnal SSSR imeni I. M. Sechenova 12/1992; 78(11):1-10.
