[Сlinicmolecular indicators of inflammatory destructive damage of the oral cavity in periodontitis in persons with various group accessories of blood.].

In order to find a connection between the alteration of oral tissues and genetic predisposition to inflammatory and destructive processes in oral media, the cytokine profile of the oral fluid of clinically healthy individuals was determined for various blood group affiliations according to the AB0 system. The group-specific features of individuals with B(III) blood group were revealed: an increase of 32,5% in the content of interleukin-6 and 63,1% in the content of interleukin-8 compared with similar data for people with 0(I), A(II), AB(IV) blood groups, which can predispose to the greatest activity of the inflammatory process in the oral cavity in individuals with antigen B. Confirmation of this fact is an increase of IgA antibodies to gliadin in the blood among patients with chronic generalized periodontitis with B(III) blood group, up to 5,00 U/ml (p<0,01), which indicates the processes of acute inflammation, and along with an increase in blood IgG antibodies to transglutaminase in comparison with a group of clinically healthy individuals, it serves as an indicator of damage to the body's connective tissue at the molecular level.

[Evaluation of the conservability of zolpidem and zaleplon in the hepatic tissue].

This paper reports the experimental data on the conservability of zolpidem and zalepion in the samples of the cadaveric liver tissue stored under different conditions. The authors describe the method that includes isolation of the substances of interest from the hepatic tissue by means of acetone extraction, their solvent and chromatographic purification, and subsequent identification with the help of the spectrophotometric technique. It is shown that zolpidem and zaleplon remain in the cadaveric hepatic tissue within 6 months after intoxication regardless of temperature which makes possible their detection, isolation, and identification by the proposed method.

[Determination of olanzapine in cadaveric blood].

The authors present the results of experimental isolation of olanzapine from the biological objects in conjunction with the detailed description of the method for olanzapine extraction from cadaveric blood with the use of one of the amphiphilic solvents (e.g. acetone), purification by solvent extraction, and TLC-screening.

[Role of superoxide anion radicals in the bacterial corrosion of metals].

It was found that seven strains of bacteria can cause corrosion damage to aluminum, its alloys, and zinc. With respect to the studied metals, the most active bacteria were Proteus vulgaris 1212 and Pseudomonas aeruginosa 969. Superoxide anion radicals were demonstrated to play a role in the initiation of corrosive damage to aluminum and zinc, while bacterial exometabolites participate in the later stages of this process.
