The objects of study are the territory of the districts of the West Kazakhstan region of the Republic of Kazakhstan adjacent to the Kapustin Yar test site: Bokeyordinsky, Zhangalinsky, Zhanibeksky, Kaztalovsky, Akzhayiksky and Syrymsky. The purpose of the work is to conduct a radioecological survey of contaminated areas and to study the content of pollutants in environmental objects, biota (rodents, fish and biosubstrates of domestic animals) by physicochemical methods to assess the risk of the landfill's impact on biota and humans. This paper presents the results of expeditionary and laboratory research on the pollution of environmental objects in the areas adjacent to the landfill. Indicators of the gamma-survey of the levels of radiation background of the surveyed territories as well as data on pollution of soil, surface and ground waters, dominant forms of plants, biosubstrates (hair of domestic animals: camel, horse, cow) are given. The generally accepted research methods were used: standard sampling methods, radiological, atomic adsorption spectrophotometry, cytogenetic (micronucleus) method. A reconnaissance and radioecological examination of environmental objects was carried out using analytical methods, which made it possible to determine the quantitative content of toxic components, the content of priority pollutants and radioactive isotopes. It has been established that the values of the volumetric activity of natural and man-made radionuclides in soil samples, drinking water and biosubstrates (pet hair, human peripheral blood samples) from settlements correspond to the value of the control level for this region. The measurements of radiation activity by gamma radiation showed that along the perimeter of the surveyed territory of the test site and in nearby settlements the radiation level is in the range of 0.06-0.014 µSv/h. A slight excess of the level of radioactivity persists in the area near the fall of missiles in the Bokeyordin region. The investigated regions are characterized by an insignificant level of background radiation, the average DER value for the regions as a whole is 0.14 µSv/h. The absolute maximum, 0.73 µSv/h, was recorded at the points of missile impact in the Kaztal region.

[Fundoscopic vessel examination in patients with severe maxillofacial phlegmons].

Using the fundoscopic vessels examination in patients with odontogenic phlegmon it was found out that in severe infectious disease of maxillofacial area the vascular figure is significantly changed. These changes confirm the growing brain swelling with intracranial hypertension as a result of heavy CNS intoxication.

[Peculiarities of endotracheal anesthesia in patients with severe odontogenic phlegmon].

The paper describes the preoperative care in 260 patients with severe phlegmons of maxillofacial area with participation of anesthesiologist and maxillofacial surgeon, allowing to lower considerably risk of anesthesia, intraoperative and early postoperative complications.

[The time periods for the formation of the permanent occlusion in children born and permanently living in a region close to a former nuclear test range]. / Sroki formirovaniia postoiannogo prikusa u detei, rodivshikhsia i postoianno prozhivaiushchikh v regione, nakhodiashchemsia vblizi byvshego iadernogo poligona.

The terms of eruption of permanent teeth were analyzed in 2000 subjects aged 3-19 years born and permanently living in a region adjacent to a former nuclear testing field in Kazakhstan. All groups of permanent teeth erupted sooner, and the rate of eruption was higher in girls than in boys. Except the 4th and 5th teeth, all groups of permanent teeth erupted sooner on the mandible than in the maxilla. The formation of occlusion was delayed in children born and living in the studied region in comparison with the children in central Russia and in the Extreme North. Eruption of some groups of teeth was delayed in older age groups. These data may be used at all pedodontics departments in organization of sanitation of children and in evaluation of the physical development and formation of orthodontic status of children.
