Abstract: In the technological processes of the construction of oil and gas wells, a variety of general-purpose inorganic chemicals are used. The ingress of these reagents into the body of drilling workers together with inhaled air, food intake, through the pores and mucous membrane is currently not sufficiently studied. The work investigated the effect of the drilling reagent brucit on the lung tissue of rats. During inhalation administration of brucite to rats, dystrophic processes were noted in their lungs, which were accompanied by the development of chronic inflammation, acute macrophage reaction. Morphometric analysis also showed a significant decrease in the area of the alveolar space and the area of the bronchus of medium caliber. In the lungs, the formation of many airless areas alternating with emphysematous-altered, the severity of which increased with the duration of exposure to the drilling reagent.           Scientific novelty:
In the work, the early unexplored effect of the drilling reagent brucit on the lung tissue of rats was determined. The categories of workers exposed to brucite at all stages of production are determined.For the first time, morphological features of the lungs in rats were determined against the background of inhaled administration of brucite particles.
Based on the results of the study, the toxicological characteristics of the drilling reagent brucit are given.
Research results:Brucite particles present in the air, when inhaled, passed through the nose, trachea, bronchi and reached the alveoli of non-linearalbinorats rats. Obviously, part of the administered dose was excreted by the body with excrement and mucus, and the other part was absorbed and then distributed to organs and tissues. A control section of a medium-caliber bronchus is shown in Figure 2.
14 days after the introduction of brucite particles, changes in lung tissue can be seen on microphotographs of the histological section. Focal fullness of the capillaries of the interalveolar septa is revealed. The changes registered on the 14th day after the introduction of brucite particles are shown in Figure 3.

Abstract: This article presents the results of the 5th Siberian Anti-Corruption Forum “Anti-corruption security: determination of threats and strategy for counteraction, held in Krasnoyarsk on December 19-20, 2019. The dialogue was organized by the Center for Combating Corruption and Legal Expertise, Law Institute of the Siberian Federal University, Governor’s Office of Krasnoyarsk Krai, Procesutor’s Office of Krasnoyarsk Krai, Administration of the Ministry of Justice of the Russian Federation for Krasnoyarsk Krai, Krasnoyarsk Regional Office of the Association of Lawyers of Russia, and the Union of Criminalists and Criminologist. The rich program of the event allowed representatives of the scientific-practical community to discuss the phenomenon of security within the applied anti-corruption aspect. The following were key topics of the scientific-practical dialogue: the concept and content of anti-corruption security as a scientific category; determination and classification of the threats to anti-corruptions security; system of ensuring anti-corruption security; improvement of federal anti-corruption policy for ensuring anti-corruption security; state and trends of corruption crimes; subjective and objective determinants of corruption crimes; anti-corruption behavioral standards as the main rules of anti-corruption security; reserves of civil society in ensuring anti-corruption security; identification and overcoming corruption stereotypes in mass consciousness; stimulation of anti-corruption behavior as an alternative to legal responsibility for commission of acts of corruption.
