Аssociation between incidence of caries of temporary teeth and pathology of the musculoskeletal system in preschool children, considering biochemical markers of connective tissue metabolism. Bodnaruk N.I., Smolyar N.I., Chukhray N.L., Mashkarinets O.O., Gan I.V. The aim is study biochemical markers of connective tissue metabolism in children with musculoskeletal disorders and their association with dental caries of temporary teeth. There were examined 232 children at the age of 5 (202 children with musculoskeletal disorders and 30 conditionally healthy children without somatic pathology). Among children with musculoskeletal disorders 68 (33.66%) had flat feet, 59 (29.21%) – postural impairment and 75 (37.13%) – combined pathology of the musculoskeletal sestem. For further research, the children were divided into three groups, 30 people in each. Group І included children with pathology of the musculoskeletal system, dental caries, without oxyproline in urine; group ІІ – with pathology of the musculoskeletal system, dental caries and oxyproline in urine; group ІІІ – with dental caries and without oxyproline in urine. Urinary excretion of glycosaminoglycans using a nephelometric test with cetylpyridinium chloride was determined. The concentration of creatinine in urine was measured in units of weight in the formation of a chromogenic complex of a solution of picric acid with creatinine in an alkaline medium. Dental status was assessed in terms of caries prevalence, deft index and severity of dental caries. The prevalence of caries of temporary teeth in 5-years old children with musculoskeletal disorders was on average 90.6±2.05%, deft index ─ 6.62±0.20, being significantly higher than in children without somatic pathology (respectively 70.83±4.45% and 5.15±0.34, р<0.001). Oxyprolin was detected only in the urine of children with combined pathology of musculoskeletal system (on average 3.53±0.11 units). The excretion rates of glycosaminoglycans in children with pathology of the musculoskeletal system, dental caries and oxyproline in urine (gr.ІІ) were two times higher than the reference range (415.37±15,09 CPCh units / 1 g creatinine, р<0.001). In theabsence of oxyproline in urine, both in somatically healthy children (gr. ІІІ) and in children with pathology of the musculoskeletal system (gr. І), the levels of excretion of glycosoaminoglycans were within the reference range (respectively 198.83±10.71 and 203.87±12.52 CPCh units / 1 g creatinine. The levels of daily excretion of creatinine were within the normal range in children of gr. ІІІ (1.17±0.13 g/day; in children of gr. І they were 2.85 times lower (0.41±0.05 g/day, p<0.001); in children of gr. ІІ – 6.5 times lower (0.18±0.02 g/day р<0.001). In children of gr. ІІ, a negative correlation was found between the levels of creatinine and oxyproline (τ= -0.68, p<0.05). The absence of oxyproline in the urine of children of gr. І and ІІІ indicates the absence of collagen decay in their bodies. In children with pathology of the musculoskeletal system against the background of undifferentiated connective tissue dysplasia (gr. ІІ), a strong, positive correlation was found between the deft index and levels of urinary excretion of oxyproline (τ= +0.77, p<0.05) and glycosaminoglycans (τ= +0.90, p<0.05), which indicates that the development of dental caries depends on the severity of the pathology of the musculoskeletal system. 

ABSTRACT
The aim: To study medical and pharmaceutical specialists’ approaches to outpatient injection treatment and their impact on the quality of medical care.
Materials and methods: The object of the study was the answers of health care professionals (n=1408) to the questions on the use of injectable pharmacotherapy in personal treatment, listed in a specially designed questionnaire on a single protocol. System analysis, questionnaire survey, statistical, comparative-and-analytical methods were used.
Results: The quality of outpatient injectable pharmacotherapy, according to the results of a survey of medical and pharmaceutical specialist, can be considered inappropriate, as in 52.9% of respondents the local adverse reaction were significantly more likely to develop compared to the respondents who did not have any local adverse reaction (χ2=21.7819, p<0.05). Most often, the following complications of injectable pharmacotherapy occurred in the analyzed respondents: pain – 45.8%; hardening – 28.3% and reddening – 21.7%. When conducting home-based treatment, 42.8% of the respondents involved persons without medical education for the execution of procedures, which is significantly more frequent (χ2=26.5556, p<0.05) in comparison with the respondents who invited medical personnel (27.0%) and used the method of self-injection (30.2%).
Conclusions: The results of a survey of medical and pharmaceutical specialists revealed that home-based injectable treatment, based mainly on their own experience, is common in the occupational environment of health care professionals.

 Flame retardants have attracted growing environmental concern. Recently, an increasing number of studies have been conducted worldwide to investigate flame-retardant sources, environmental distribution, living organisms’ exposure, and toxicity. The presented studies include the degradation of 4,40 -isopropylidenebis(2,6-dibromophenol) (TBBPA) by ozonolysis and photocatalysis. In the photocatalytic process, nano- and micro-magnetite (n-Fe3O4 and µ-Fe3O4) are used as a catalyst. Monitoring of TBBPA decay in the photocatalysis and ozonolysis showed photocatalysis to be more effective. Significant removal of TBBPA was achieved within 10 min in photocatalysis (ca. 90%), while for ozonation, a comparable effect was observed within 70 min. To determine the best method of TBBPA degradation concentration on COD and TOC, the removals were examined. The highest oxidation state was obtained for photocatalysis on µ-Fe3O4, whereas for n-Fe3O4 and ozonolysis, the COD/TOC ratio was lower. Acute toxicity results show noticeable differences in the toxicity of TBBPA and its degradation products to Artemia franciscana and Thamnocephalus platyurus. The EC50 values indicate that TBBPA degradation products were toxic to harmful, whereas the TBPPA and post-reaction mixtures were toxic to the invertebrate species tested. The best efficiency in the removal and degradation of TBBPA was in the photocatalysis process on µ-Fe3O4 (reaction system 1). Theexamined crustaceans can be used as a sensitive test for acute toxicity evaluation.

У статті проаналізована ідея французького філософа Анрі Берґсона, згідно з якою філософування полягає у тому, щоби створювати нові концепти, якомога більше уточнювати терміни, виковувати нові слова. Також експлікована процедура концептуалізації. Вона полягає у наданні філософського змісту звичайним повсякденним словам чи словосполукам, наприклад, слово élaboration (розроблення). У підсумку виникають цілі сімейства концептів, які сукупно можна назвати концептивними елементами. Вказано на важливу роль зв'язку між концептотворенням та філософським перекладом. Цей з в ’язок описаний на прикладі твору Берґсона «Можливе та реальне». Ключові слова: філософський переклад, Берґсон, Дельоз, концепт, концептуалізація.
