X-ray and anatomical features of the lower jaw alveolar cortical layer in children.

Introduction: the world studies showed the interest in measurement of the buccal or anterior cortical plate thickness. Data indicate a significant superiority of the spongy substance over the compact one in the distal part of the jaw, which makes it possible to think about a higher effectiveness of transcortical injections. The empirical "rule of 10″ provides for the choice of a method of anesthesia in children for primary teeth but demonstrates difficulties with high-quality anesthesia accompanied for permanent teeth.

[Intensity of processes of oxidative modification of proteins in women's and cow's milk].

Breast milk is a source of all the essential nutritional components necessary for the full growth and development of the child, therefore, it is necessary to study its composition and physical and chemical properties in order to adapt human milk substitutes. Adapted infant milk formulas are produced mainly from cow's milk, bringing formula nutrient composition closer to the composition of women's milk, adapting it in accordance with the requirements of the infant body. However, technological processes for the production of dairy products contribute to the activation of oxidative reactions, the violation of protein conformation.

[Experimental investigation of efficacy and safety of different methods of endoscopic hemostasis].

Treatment of ulcerative gastroduodenal bleedings remains one of the most pressing problems in urgent surgery. Available methods of endoscopic hemostasis are not fully eligible to safety requirements, effectiveness and reliability. In this connection persist high levels of general and postoperative mortality in our country and around the world.

[Hygienic risk factors of congenital malformations].

The frequency of multiple congenital malformations, central nervous system and genital malformations were found to be associated to the magnitude and duration of ecological load. Xenobiotics identified in the ambient air of a large industrial center pose an increased risk for antenatal malformations. The largest number of statistically significant correlation coefficients was established between the study variables at a delay lag of 2 years.

[The monitoring of the congenital malformations development in children: problems and prospects].

In various countries all over the world, the congenital malformations are among the leading causes of infant mortality and children disability. The historical approach is applied to consider epidemiological monitoring as a practice preceding the comprehensive analysis of causes and conditions of congenital malformations formation. The primary tasks of monitoring study are established and means of their implementation as well.

[Characterization of the sanitary situation in the Kurgan Region].

The aim of this survey was to study the ecological state in the Kurgan Region in the period of 1993 to 2003. The survey showed the west and northwest part of the Kurgan Region to be areas at risk for environment-dependent diseases. The major risk factors included a high pollution of water sources with limited water resources due to the radioactive pollution occurring in the 1940s to the 1950s in some areas of the region; transformation of natural landscapes caused by spring floods and soil erosions among other things.

[Analysis of chromosomal aberrations in the chorionic cells of induced abortions as a method for estimating the level of spontaneous mutagenesis].

Chromosomes were morphologically studied in the chorionic fibroblasts of induced abortions. Chorionic villi biopsy specimens taken during 103 abortions at gestational weeks 6-12 served as a material for this investigation. They were taken from women with pregnancies interrupted due to that there were social indications.

[Prophylaxis of insufficiency of gastrointestinal anastomoses].

Experimental and clinical results of use of fibrin glue for strengthening "high risk" sutures of anastomoses in elective surgery of the esophagus, stomach and urgent abdominal surgery are presented. In experimental studies this glue permitted to increase mechanical strength and containment of anastomosis, to accelerate microbial elimination, activated reparative processes. In clinical practice fibrin glue permitted to avoid suture insufficiency of gastrointestinal anastomoses in the most unfavorable conditions (peritonitis, acute intestinal obstruction, oncological process, etc).

[The destruction of microscopic organisms by their irradiation with a special form of UHF electromagnetic signals].

Electromagnetic signals of special form produced by an ultra-high frequency generator were used to destroy various microorganisms: baker's yeast; blue-green alga Nostoc muscorum; mold fungus; and two flagellates, plant flagellate Euglena gracilis and an animal flagellate parasitizing on humans. The control samples before irradiation and experimental samples damaged and destroyed by irradiation were examined on a microscope with a computer system of image analysis. The results are presented as computer graph images.

[The system of collection, processing, storage and retrieval of x-ray diagnostic images].

The paper describes a system able to combine conventional techniques of diagnostic x-ray imaging with direct digital imaging on the original receiver with a resolution of 1.2 lin/mm.
