Selfregulation

Application of measured skin stimulation (contrary to classic dermographism) revealed a microcirculation variety of changes and restoration (skin vessel selfregulation). The reaction phases were measured versus classic dermographism. The types of skin vessel reactions is found to depend upon the stimulus strength. The dynamics of pattern change of skin vessels is described to differentiate hatched zone (central) and surrounding ones. A tendency of appearing of the surrounding zone before the central those was found...

The authors discuss facts and hypotheses on the effects of benzohexonium upon the motor activity of the intestine and the significance of N-cholinolytics for prophylactics and treatment of postoperative pareses of the gastrointestinal tract. The ganglioblockers possess antistress effect, reduce the degree of pathological vegetative reactions and facilitate realization of the mechanisms of selfregulation of functions of the small and large intestine. Using benzohexonium during operation and in the first days after it makes the intestinal pareses less frequent...

Hydroelectrolytic equilibrium alteration in dialysis patients before dialytic treatment consists in extracellular volume expansion and hyperkalemia. Extracellular volume expansion is due to salt and water retention. Because of the self-regulation phenomenon of cell volume, it is made prevalently at the expense of extracellular volume. Hyperkalemia derives not only from alimentary K+ retention but, above all, from the K+ intracellular transfer into extracellular volume for tamponage of acid load, owing to the same selfregulation of cell volume and to the reduction of Na+/K+ pump activity with a subsequent change in Ki/Ke ratio...

Blood pressure, heart rate and haemodynamics parameters in dispatchers of electric networks were studied in productive conditions under two days rotation of 12-hour shifts (17 subjects, 1224 subject-observations). It was revealed, that taking and giving periods of the shifts activate cardiovascular system work to the pronounced extent (significant increase of blood pressure at the beginning and in the end of the shifts and heart rate--at the beginning of the shifts). That is accompanied with unfavourable changes of bloodcirculation selfregulation (BCS): Predominantly heart BCS that is forming at the beginning of the shifts, especially in the evening, gradually convert towards the mainly vascular one, that is especially pronounced after 8 hours of continuous working in the day shifts...

Traditional concepts of avolition (Kraepelin) and ambivalence (Bleuler) among schizophrenic patients can be interpreted in the light of present ideas of motivation and volition. Accordingly schizophrenic patients are marked both by oppositional high hope and fear components of implicit motives and by the impairment of volitional selfregulation, which both are vulnerability factors. In an environment lacking stimuli the patients cannot surpass their ambivalence through volitional selfregulation and remain passive...

In their work as counselors in the field of organisational psychology and staff development, the authors are constantly in search of ideas which are relevant to hospital work. They became aware of the concept of 'Fraktal factory', arising from reports of peoples' experiences. The concept refers to the synergistic organisation of decentralised, interdisciplinary, selfregulating units- 'Fraktale'. They found the concept convincing, it seems to represent an important principle for hospitals. It is a holistic concept...

Labrocytes situated in the external tunica of the cat basis cerebri arteries have been studied by means of Falck's method and electron microscopically. It has been stated that dilated areas in islets of the mast cells, having ultrastructure peculiar for actively secreting formations, are situated at the distance of 80-100 nm from the smooth muscle cells of the middle tunica. Close structural and functional relations have been found to exist between the adventitial labrocytes and neural conductors of the arteries...

Both reflex phenomena of the masticatory musculature (jaw-jerk-reflex and silent period) were studied in the masseter muscle under standardized reflexogenic conditions in terms of the strength of the stimulus and initial muscle tension. The measurements were carried out with loading forceps. The reflex time for the selfregulating reflex of the masseter for 11 subjects ranged from 7.4 to 9.4 ms; the latency time for the silent period, from 13.9 to 18.1 ms; the duration of the latency period, from 11 to 23 ms...

Although he does not always mention it, A. Janov agrees with many of W. Reich's opinions on theoretical-philosophical foundations and the theory of neurosis and other illnesses; from their criticism of society both of them develop the demand for prophylaxis of neurosis as a prerequisit for their common utopia of a selfregulated society. Primal therapy and Orgon therapy are two different forms of the "New Body Therapies" group. The authors disagree with their views of the physiological nature of Pain (A...

The water flow according to the osmotic gradient increased under the action of 1 mU/ml of antidiuretic hormone (ADH) from 0,049 +/- 0.017 to 1.31 +/- 0.29 mcl/cm2 min in the presence of hemosorbent SKN in the solution of the frog bladder serous membrane and from 0.054 +/- 0.015 to 0.67 +/- 0.15 mcl/cm2 min without a sorbent. The effect of polyethylene glycol 400 hyperosmotic solution on the water, cAMP and theophylline penetration was not intensified after hemosorbent use. ADH inhibitor-binding substances are present in the blood serum...

Cholesterol-acceptor and cholesterol-transport functions of high density lipoproteins appear to occur by means of the principle of selfregulation as these lipoproteins (particles) included a number of active units responsible for their biological function. These units were as follows: a) protein-lipid structure of surface monolayer of high density lipoprotein particles, which enables to intercalate the molecules of unesterified cholesterol, b) the enzymatic system, responsible for cholesterol esterification (lecithin-cholesterol acyltransferase--LCAT), involving the enzyme second substrate lecithin and activator apoprotein A-1, c) the system of nonenzymatic controlled transport of cholesterol esters, developed during the LCAT-reaction, involving the lipid-transport protein...

Parasitic system is determined as a parasite's population in interaction with its natural habitat (host's population). Epidemiology, epizootiology and epiphitology as well as virology, microbiology, protozoology and helminthology study applied aspects of parasitic systems. The latter are characterized by four general principals determining selfregulation mechanisms of these systems: heterogeneity of interacting populations, their dynamic variability, phase functioning, dependence on conditions.

A total of 125 students, aged from 6 to 18, with dysplasia of the permanent teeth were examined by a qualified pediatric stomatologist and orthodontist. Dental-jaw deformities (DJD) were established in 74.40% of all examined students. Most frequent proved to be the combination of DJD with hypomineralization in mixed dentition (34.41%) and with hypoplasia in permanent dentition--20.45% and hypomineralization--10.75%. The analysis with a view to the type of DJD revealed that the combination between dysplasias of the permanent teeth and deformities in the proportion of the jaws was most frequent (56...

For bigenesis-a particular kind of systmogenesis-to occur, certain physical and informative requirements were indispensable, especially: (1) the selforganization of new kind of negative feed-backs supported by the trans-substantial channels of information. These were certainly at first organized only on the submolecular level, each of them consisting of many charge-transfer connections. The accomplishment of requirement (1) depends on (2) and (3): (2) the organization of a sufficiently complex structure inside the agglomerated system...

In chronic experiments on cats, automatic regulation of polarizing current, monitored with the EEG changes, aided to study elements of the cerebral selfregulating system. The method proved effective for influencing the functional state of the structures to be regulated which revealed itself in long-lasting shifts of theta-rhythm, in changes of excitability and readjustment of EPs. Three types of connections between the temporal cortex and a number of cerebral modulating structures: rigid (positive and negative) and flexible those, were revealed...

Data on the extensiveness and intensity of infection of Kildin island cod with Echinorhynchus gadi in various seasons are given. E. gadi was proved to have a one-year life cycle and Gammarus duebeni as an intermediate host in the lake. A change of the parasite generations occurs in late summer--autumn. A high extensiveness (100%) and intensity of Kildin cod infection with E. gadi depends on the feeding habits (monophagy) and narrow distribution range of the host. Infection intensity is directly correlated with the fish age...

The slow reacting substance of anaphylaxis (SRS-A) belongs to a group of substances which produce a slow progressive and sustained contraction of some smooth muscles. It is released by the interaction of the antigen with certain antibodies; in humans through the interaction with the IgE or reagine. The SRS-A is a heat-labile sustance, chemically unstable, of an acid character, with a low molecular weight. It is not destroyed by the action of proteolytic enzymes. Its molecular structure has not yet been elucidated...
