The aim: Is to assess the functional state of parotid glands and general secretion in patients with compression, dislocation dysfunction of TMJ, to correct the revealed disorders. Materials and methods: We examined 46 patients with dysfunction of TMJ. Examination included TMJ zonography and salivary glands sonography. We studied the general and parotid secretion, transparency, viscosity, pH of the oral fluid and the secretions of the parotid glands before and after treatment. The treatment of dysfunction and hyposialosis included the repositioning of the articular heads of the lower jaw in the correct anatomical position, the use of a repositioning plate on the posterior teeth at the compression side of the articular head, bougienage of the duct of the parotid gland, administration of 10% magnesium-mineral solution of bischofite into the gland. Results: In patients with TMJ dysfunction, a significant decrease in the oral fluid content was noted before treatment. The saliva transparency was reduced, the viscosity was increased, the pH was slightly acidic. A study, which was carried out a month after completion of the course of treatment showed that all the studied parameters corresponded to those in healthy individuals. Conclusions: The study confirmed that in compression and dislocation dysfunction of TMJ, there are disorders of the functional state of the salivary glands.

Aim. This research was designed to study the functional state of masseters in patients with hypermobility of heads of the mandible by the traditional treatment and using transcranial electrostimulation.Materials and methods. There was conducted the examination and treatment of 80 patients with hypermobility of heads of the mandible. All patients were divided into two groups: the 1st group (n=20) received standard treatment, the second group (n=60) received traditional treatment with the inclusion of myogymnastics, massage in the temporomandibular joint area, transcranial electrostimulation, use of the apparatus of A. Sidorenko that limits the movement of the lower jaw. The control group included 10 volunteers without the pathology in the temporomandibular joint. The masseters were studied by an electromyography method before the treatment, in 1 month and in 6 months after the treatment using the computer and Miokom electromyograph. The obtained results were processed with use of the "Statistica Statsoft" program version 6.1 and "Microsoft Excel 2010".Results. The analysis of the amplitude of bioelectric potentials of the masseters made it possible to establish that when using transcranial electrostimulation and the proposed intraoral apparatus of Sidorenko AN, limiting the amplitude of mouth opening, in 6 months after the end of the treatment in patients with hypermobility of the lower jaw the increased bioelectrical activity of the masseters in the state of relative physiological dormancy disappeared, the amplitude of their contractions (93.2%) normalized.Conclusion. The results of the electromyographic study of temporal and masseter muscles made it possible to conclude that use of the transcranial electrostimulation and the intraoral apparatus of Sidorenko AN, limiting the movement of the lower jaw, has a positive effect on the functional state of the muscular apparatus in patients with hypermobility of the mandible heads. In the state of relative physiological dormancy the bioelectric potentials of the temporal and masseter muscles decrease, the amplitude of the bioelectric potentials while chewing and maximum compression of the jaws increases.

Research  background  and  hypothesis.  Traditional  time  series  analysis  techniques,  which  are  also  used  for the analysis of cardiovascular signals, do not reveal the relationship between the  changes in the indices recorded associated with the multiscale and chaotic structure of the tested object, which allows establishing short-and long-term structural and functional changes.Research aim was to reveal the dynamical peculiarities of interactions of cardiovascular system indices while evaluating the functional state of track-and-field athletes and Greco-Roman wrestlers.Research methods. Twenty two subjects participated in the study, their average age of 23.5 ± 1.7 years. During the study standard 12 lead electrocardiograms (ECG) were recorded. The following ECG parameters were used in the study: duration of RR interval taken from the II standard lead, duration of QRS complex, duration of JT interval and amplitude of ST segment taken from the V standard lead.Research  results.  Significant  differences  were  found  between  inter-parametric  connections  of  ST  segment amplitude and JT interval duration at the pre and post-training testing. Observed changes at different hierarchical levels of the body systems revealed inadequate cardiac metabolic processes, leading to changes in the metabolic rate of the myocardium and reflected in the dynamics of all investigated interactions.Discussion and conclusions. It has been found that peculiarities of the interactions of ECG indices interactions show the exposure of the  functional changes in the body at the onset of the workload. The alterations of the functional state of the body and the signs of fatigue, after athletes performed two high intensity training sessions per day, can be assessed using the approach of the evaluation of interactions between functional variables. Therefore the evaluation of the interactions of physiological signals by using time series analysis methods is suitable for the observation of these processes and the functional state of the body.Keywords: electrocardiogram, time series, functional state.

Summary. The disbalanced feeding and the uneven distribution of micro- and macroelements in the environment leads to a trace element, in particular hypomelanosis. To accelerate the growth and preservation of young farm animals include in the diet of various biological additives and drugs, which include selenium. For stimulation of weight gain in the livestock industry, as well as for the prevention and treatment of pathological processes in addition to micro - and macrouse amino acids, primarily methionine. The aim of this work was to study the influence of composition of DAFS-25+Polizon on morpho-biochemical parameters of blood and functional state of the liver in fattening bulls of black-motley breed in the conditions of the Republic of Bashkortostan. Experiments using were conducted on bull-calves of black-motley breed of the properties in the properties age from 6 to 15 months. The first experimental group during the experiment was additionally given the composition of DAFS-25+Polizon at a dose of 2 mg/kg, the animals of the control group received a standard diet. To assess the impact of the composition DAFS-25+Polizon on metabolism cattle studied morphological and biochemical indicators of blood and conducted histological examination of the liver. It is established that the use of the composition of DAFS-25+Polizon at a dose of 2 mg/kg increases the number of erythrocytes and hemoglobin in the experimental group and reduces the amount of white blood cells. The serum content of total protein, phosphorus and calcium increases in the group of experimental animals. Microscopic examination of the liver revealed no changes in the structure of the organ and hepatocytes in the experimental group, whereas in the control group hemodynamic disorders and dystrophic changes in liver cells were observed. Thus, the use of the composition DAFS-25+Polizon at a dose of 2 mg/kg of live weight in fattening bulls black-and-white breed contributes to the increase of redox processes in the body, stimulation of metabolism, prevent the development of liver disorders of cellular mechanisms of metabolism, optimizes the structure of the liver, which generally provides higher productivity.

ABSTRACT The effect of synthetic LH-RH was studied in 100 patients with various types of ovarian insufficiency by following up the FSH- and LH-levels in plasma. LH-RH was administered in doses of 12.5, 25 and 100 μg as a rapid intravenous injection. The patients were classified according to the endocrine state of the pituitary as evidenced by the urinary gonadotrophin levels. A clear correlation between the functional state of the pituitary and its responsiveness to exogenous LH-RH was demonstrated. Most of the patients with undetectable low urinary gonadotrophin levels failed to respond. The majority of patients with gonadotrophin excretion in the normal range and those with elevated levels reacted with a dose dependent increase in circulating LH. The amount of liberated FSH however was related to the injected dose only in patients with high gonadotrophic excretion. The present study indicates that synthetic LH-RH provides a useful tool in the evaluation of the pitutiary function particularly in patients with low and with undetectable gonadotrophin excretion. The data presented in this paper also demonstrate that the functional state of the pituitary is clearly reflected by the urinary gonadotrophin levels.
