Integrated Assessment of Neurodynamic and Vegetative Indicators in Adolescents: Age- and Gender-Related Differences and Typological Features.

We examined schoolchildren aged 11-16 years (n = 930) and determined the features of neurodynamic and vegetative parameters associated with age and sex and the factors affectingthe psycho-physiological statusof adolescents. An analysis of the relationship of studied parameters in adolescents with different types of autonomic regulation showed thatthe evaluation of functional constitution has prognostic significance since it is indicative of the adaptation potential.

[The Attitude to One's Own Health Among Native Residents of Yakutia].

The study was carried out concerning value reference points and attitudes of native population of the Republic of Sakha (Yakutia) intended for health preservation. The analysis was applied to answers of 292 respondents residing in rural area of Yakutia. The analysis of answers of value motivation section demonstrated that for most respondents their health is a priority value of life. At that, most of respondents misunderstand and underestimate role of health in their life because they are unaware of health as an instrumental value. The health as an instrumental value gives its priority to persistence and diligence and hence ranks lower as compared with terminal value. The respondents assume that health mainly depends on diet, life-style, ecology. The results of analysis of answers to questions of "emotional" and "behavioral" sections testify in most of the respondents absence of comprehension about responsibility for one's own health, inadequate commitment to healthy life-style and passive attitude to health. The more active attitude to health is established in respondents of mature age that is rather related to deterioration of well-being feeling and presence of chronic diseases. In the younger age, most of respondents consider they are healthy and hence ignore prevention of diseases. Thereby, in spite of that health is mentioned by respondents as one of priority values most respondents are missing both attitudes to health preservation and clear-cut strategy of health-preserving behavior. In conditions of cardinal alteration of traditional way of life and life-style of native population of the North, behavioral habits of self-preserving behavior helping to survive in the severe climate conditions became inadequate. Nowadays, it is necessary to develop a new behavior strategy of health preservation.

[COMPARATIVE CHARACTERISTICS OF IMMUNE STATUS OF PATIENTS WITH CHRONIC FORMS OF VIRAL HEPATITIS B, C, D AND HEALTHY INDIVIDUALS].

AIM: Evaluate immune status in patients with chronic hepatitis (CH) depending on type of causative agent and severity of the infectious process. MATERIALS AND METHODS: 232 residents of Yakutia including 127 patients with various forms of chronic hepatitis and 105 healthy individuals were examined. Relative levels of mature T-lymphocytes (CD3⁺), T-helpers (CD4⁺), T-suppressors (CD8⁺), B-lymphocytes (CD72⁺) and naturalkillers (CD16⁺) were studied by flow cytometry, as well as concentration of sera immune globulins of classes A, M and G by ELISA. RESULTS: In patients with chronic hepatitis of various forms, a decrease of expression of differentiating antigens - CD3⁺, CD4⁺, CD72⁺ on the surface of lymphocytes and concentration of sera immune globulins was established. In CHD patients in phase of monoreplication high activity of the infectious process is accompanied by a shift of immune regulatory index to the increase of activity of cytotoxic cells with simultaneous development of deficiency of mature functionally active T-lymphocytes. In the -group of patients with hepatitis D virus with liver cirrhosis normal concentration of sera immune globulins is retained against the decrease of the number of T-helpers and B-lymphocytes. CONCLUSION: In patients with various forms of viral hepatitis acquired immune deficiency can emerge, which is often accompanied by enhancement of NK-cell activity. The noted reduction of the number of mature functionally active T-cells, as well as main classes of sera antibodies could be con- nected with immune system load during a chronic infectious process.

[Experience in the pre-hospital treatment of acute coronary syndrome with metoprolol succinate].

Patients with acute coronary syndrome and elevated ST segment in the pre-hospital phase were treated with metoprolol succinate (MS) and thrombolytic therapy. Severe and moderate pain decreased by 54.1 and 16.1% respectively within 60 min after MS intake. Systolic (SAP) and diastolic (DAP) arterial pressure dropped by 35.7 and 16.8 mmHg during the same period. The heart rate (HR) decreased by 25.1 beats/min. 21.8 and 25.3% of the patients showed positive dynamics of ST segment 90 and 180 min after intake of MS. The height of the ST segment was normal in 18.4 and 31.0% of the patients respectively. No cases of external heart rupture were documented at autopsy whereas it was a cause of death in 39.1% of the patients given standard thrombolytic therapy. It is concluded that the use of MS starting from the pre-hospital stage in patients with acute coronary syndrome decreases pain intensity. HR, DAP and SAP and helps to prevent heart rupture.

[Terahertz radiation influence on number and development dynamics of offspring F1 of fruit fly females under stress].

Virgin fruit fly females were stressed by placement into a confined space without food for 2.5 hours. Some flies were subjected to terahertz radiation (0.1-2.2 THz) for the last 30 min. Then females were copulated with males. Offspring F1 from oocytes which were mature or immature at exposure (oviposition in 1-2 or 9-10 days after irradiation) was studied. Stress induces a rejection of the offspring maturation dynamics to imago from external control (offspring of flies which was maintained in standard conditions). In offsping from mature oocytes of irradiated flies the dynamics of male maturation to imago was different from internal control (offspring of stressed unirradiated flies). The number of imago males decreased. The dynamics of female maturation to imago coincides with laboratory control. In offsping from immature oocytes of irradiated flies the dynamics of female and male maturation and the number of flies were not significantly different from the internal control. It was concluded that only mature oocytes are sensitive to THz radiation influence.

[Prehospital stage of medical aid to patients with acute coronary syndrome and elevated ST segment].

We studied effect of time on the outcome of acute coronary syndrome and elevated ST segment at the prehospital stage. Logistic regression analysis revealed two time-dependent predictors: "symptom-needle" time and total call service time. In patients undergoing prehospital thrombolysis, these indices (88 and 85 min respectively) reliably predicted the probability of fatal outcome. Their values of 71 and 77 min respectively predicted the risk of unfavourable outcome. The total call service time may serve as an indicator of the quality of work of an ambulance crew at the prehospital stage of management of acute coronary syndrome with elevated ST segment.

[A method for covering the subcutaneous fat in the surgery of postoperative ventral hernias]. / Sposob obkladyvaniia podkozhnoi kletchatki v khirurgii posleoperatsionnykh ventral'nykh gryzh.

The authors suggested a method for covering the subcutaneous fat and tested it in 115 operations for postoperative ventral hernias. The method is based on vertical arrangement of gauze napkins covering one another in turn by one third. All of the operated on patients had no inflammatory complications of the postoperative wound. The authors claim this method to be among the elements preventing postoperative inflammatory complications of wounds.
