    Relevance. The prevalence of posture defects, according to various researchers, is from 0.6% to 78%. The disruptions in the posture biomechanics leads to excessive stress on the main joints of the human body including temporomandibular joint.Objective. The research aimed to study the prevalence of violations of the anatomical and functional system "posture-occlusion" and the structure of early signs of degenerative-dystrophic changes in the spine in medical students.Materials and methods. 130 students of medicals and dental faculties (including 42 men and 88 women) with posture disorders were examined in accordance with special questionnaires developed at the department.The assessment of the functional state of the spinal was carried out using motor tests by the method of Goryana G.A. and complaints of pain according to the 10-point numerical scale of pain "NSP". The malocclusion was assessed according to the method of Khvatov depending on the type of mandibular displacement. Statistical analyses with program IBM SPSS Statistic Base v.22. Results. It has been found that 78 students or 60% did not have restricted and widespread osteochondrosis and pain degree was lower than 5 points.A high prevalence (40%) of combined deformity of posture and displacement of the lower jaw in combination with pain syndrome was established. Along with restricted osteochondrosis 38 (73,08%), distal type of lower jaw displacement was more commonly seen amongst students with postural defects 35 (67,31%). These clinically manifested a pain level of more than 5 points. Signs and symptoms of a combined pathology posture-occlusion were more common among women (37 patients, or 71.15%) than men (15 patients, or 28.85%)Relevance.

    Cholinesterase inhibitors can be used for treatment of neuropsychiatric symptoms and functional impairments in neurodegenerative pathologies such as Alzheimer’s and Parkinson’s diseases.Aim. To synthesize and assess the inhibitory activity of adamantyl-containing 5-substituted N-benzyl and N-phenacylthiazolium salts against butyrylcholinesterase and acetylcholinesterase.Results and discussion. The synthesis of 3-aroylmethyl- and 3-arylmethyl-5-(2-acyloxyethyl)-4-methylthiazolium salts included preparation of 5-acyloxyethyl thiazole derivatives by the reaction of 5-(2-hydroxyethyl)-4-methyl-1,3-thiazole with the corresponding adamantoyl- or adamantylacetyl chlorides. The derivatives of 5-acyloxyethyl thiazole were quaternized in the reaction with benzyl or phenacyl halides. The studies in vitro have shown that the compounds synthesized inhibit butyrylcholinesterase with IC50 values in the micromolar range. Some of them exhibited selectivity over acetylcholinesterase. The molecular docking was performed for understanding the mechanisms of the enzyme-inhibitor complex formation.Experimental part. The synthesis of the intermediate and target compounds was carried out by the classical methods. The structures of compounds were proven by NMR 1H-spectroscopy and elemental analysis. The methods of enzymatic kinetics were used for determination of the inhibitory effects of the compounds synthesized. Calculations by molecular docking were carried out using Autodock 4.2 program.Conclusions. 3-Aroylmethyl- and 3-arylmethyl-5-(2-acyloxyethyl)-4-methylthiazolium salts with adamantylcontaining substituents in position 5 can selectively inhibit butyrylcholinesterase compared to their effect on acetylcholinesterase.Π˜Π·Π²Π΅ΡΡ‚Π½ΠΎ, Ρ‡Ρ‚ΠΎ ΠΈΠ½Π³ΠΈΠ±ΠΈΡ‚ΠΎΡ€Ρ‹ холинэстСраз ΠΌΠΎΠ³ΡƒΡ‚ ΠΈΡΠΏΠΎΠ»ΡŒΠ·ΠΎΠ²Π°Ρ‚ΡŒΡΡ для лСчСния Π½Π΅ΠΉΡ€ΠΎΠ΄Π΅Π³Π΅Π½Π΅Ρ€Π°Ρ‚ΠΈΠ²Π½Ρ‹Ρ… Π·Π°Π±ΠΎΠ»Π΅Π²Π°Π½ΠΈΠΉ, Ρ‚Π°ΠΊΠΈΡ… ΠΊΠ°ΠΊ болСзнь ΠΠ»ΡŒΡ†Π³Π΅ΠΉΠΌΠ΅Ρ€Π° ΠΈ болСзнь ΠŸΠ°Ρ€ΠΊΠΈΠ½ΡΠΎΠ½Π°.ЦСль Ρ€Π°Π±ΠΎΡ‚Ρ‹.
