[THE DIFFERENCES OF CHANGES IN BODY WEIGHT ON THE HYPERTENSION IN ADOLESCENTS 12-13 YEARS].

The aim of the research was to study the differences of overweight, obesity to the level of AH among 12-13 years old. We carried out a cross-sectional study of 1493 adolescents aged 12-13 years in Semey. The risk factor of diseases of the circulatory system was studied, such as obesity and its correlation with the level of arterial pressure. The population with normal blood pressure (BP) was 87.4% (n=1305), persons with arterial hypertension (AH) (1 and 2 degrees) 12.6% (n=188). There were no statistically significant differences in prevalence of AH by ethnicity (Pearson's χ² criterion = 0.18, df=1, p=0.671). By weight, body mass index (BMI), systolic blood pressure (SBP), diastolic blood pressure (DBP), statistically significant differences were detected (p <0.001). According to the data of the study, the following data were revealed in the structure of individuals with normal BP according to the value of BMI: underweight in 29.5% (n=385), normal weight in 65.1% (n = 850), overweight in 4.7% (n=61), obesity in 0.7% (n=9). In the structure of persons with arterial hypertension, the BMI value was: underweight 12.3% (n=23), normal weight 66.7% (n=126), overweight 19.4% (n=36), obesity 1.6% (n=3). A significant prevalence of hypertension in the population of adolescents aged 12-13 years was found, roughly to 12.6%. In the groups of adolescents with normal BP and AH, statistically significant differences in the ratio of the body weight categories of adolescents determined by BMI were revealed, to a greater extent this was related to overweight.

[Method of multilayer assembly as alternative to antibacterial coverings of medicobiological implants].

Department of Traumatology and Orthopedics Almaty Kazakh Medical University of Continuing Education; 4. Moscow Regional Research Clinical Institute, Russia Resume: in this report we present the results on the use of the method of layer-by-layer (LbL) for obtaining antimicrobial coatings for biomedical implants. As the substrates were used silicon titanium implants and silicon plate. For the obtaining multilayer coatings on the surfaces of the samples were used as the polycation--chitosan and polyanion--carboxymethylcellulose sodium. On the surface multilayer were deposited antibacterial preparations: Triclosan-2,4,4'trichloro-2' hydroxyphenyl ether, silver ions and iodine. Microbiological studies were conducted on the museum strains: E. coli, Candida and Staf. Preliminary antibacterial studies on these microorganisms showed high activity multilayer coating containing triclosan.

[Immunochemical properties of the excretory-secretory antigen of Trichinella spiralis].

In vitro cultivation of Trichinella spiralis provided data on the structure of somatic and excretory-secretory antigens of T. spiralis larvae, their immunochemical properties were studied. The findings suggest that work should be continued to produce monoclonal antibodies and to develop highly sensitive and specific ELISA test systems for the diagnosis of human and animal trichinosis.
