Introduction. As a trace element, selenium is present in humans as part of selenoproteins. It improves the work of the antioxidant defense system and produces a strong immunomodulatory effect. Selenium is part of about 30 biologically active compounds of human body. However, selenium deficiency is considered a global problem. The research objective was to determine the selenium content in the developed pasta products. Study objects and methods. The study featured laboratory samples of pasta made from a mix of whole wheat spelt flour, buckwheat, and low-temperature drying powders of broccoli and celery. The selenium content was determined by atomic absorption spectroscopy with electrothermal atomization with a palladium nitric acid matrix modifier. The experiment employed a Hitachi 180-80 atomic absorption spectrophotometer. To determine the selenium content, the samples underwent wet mineralization in nitric and perchloric acids. Adding hydrogen peroxide and ethanol made it possible to convert selenium from inorganic and organic forms into selenite ions. Results and discussion. The research involved domestic natural raw materials. The components proved to be good sources of selenium, which means that they can be used to produce functional products. The selenium content ranged from 105.7 ± 22 mkg/kg to 302.5 ± 17 mkg/kg in the samples. Taking into account the loss of selenium during cooking, the selenium content in 100 g of the finished product ranged from 13.5% to 38.5 %. Conclusion. The developed pasta products proved excellent sources of selenium. The use of buckwheat flour and vegetable powders in the formulation of wholegrain spelt dough increased the selenium content in the pasta by 40.7–186.2 %. The obtained results can be used for tables of the chemical composition of Russian food products.

Among the relevant for the modern pharmacy problems, there is a need for the rational complex use of known medicinal plants, as well as the search for new sources of natural biologically active compounds in order to expand the list of official medicinal plants and raw material base. Species of genus Geum L. contain a number of biological active substances and are promising sources of raw materials for the production of antimicrobial, astringent, anti-inflammatory, and hemostatic medicines. Pharmacological activity of these plants results from their multi-component chemical composition, including tannins, flavonoids, macro- and microelements and other compounds. The aim of thе study was to compare the elemental composition of herb and rhizomes with roots of G. urbanum L., G. aleppicum Jacq. and G. rivale L. of Ukrainian flora. The objects of the study were the samples of herb and rhizome with roots of G. urbanum L., G. aleppicum Jacq. and G. rivale L. (dried raw materials) which were collected in the Kharkiv region, Ruski Tishki village, in June-August 2018–2019. The determination of the qualitative composition and quantitative content of elements was carried out by atomic absorption spectroscopy with atomization in an air-acetylene flame using a spectrometer CAS 120 («Selmi», Sumy, Ukraine). In the studied samples, 19 elements were determined, including 5 macroelements and 14 microelements. The data about accumulation of elements in investigated herb of G. urbanum L., G. aleppicum Jacq., G. rivale L. can be arranged in descending order as follows: K > Ca > Si > Mg > P > Fe > Al > Na > Sr > Zn, and in rhizomes with roots as follows – K > Si > Ca > Mg > Fe > P > Al > Na > Sr > Zn. The content of toxic elements such as cobalt, cadmium, arsenic, and mercury was within the permissible limits for plant raw materials and food. For the first time, a comparative study of the macro- and microelement composition in herb and rhizomes with roots of G. urbanum L., G. aleppicum Jacq. and G. rivale L. has been carried out. Using the method of atomic absorption spectral analysis, 19 elements have been identified and their content has been determined, among which К, Ca, Mg, Si, P, Fe, Al, Na, Mn, Zn predominantly accumulate.

Antioxidant Defense System

Reactive oxygen species (ROS) are frequently produced during viral infections. Generation of these ROS can be both beneficial and detrimental for many cellular functions. When overwhelming the antioxidant defense system, the excess of ROS induces oxidative stress. Viral infections lead to diseases characterized by a broad spectrum of clinical symptoms, with oxidative stress being one of their hallmarks. In many cases, ROS can, in turn, enhance viral replication leading to an amplification loop. Another important parameter for viral replication and pathogenicity is the nutritional status of the host. Viral infection simultaneously increases the demand for micronutrients and causes their loss, which leads to a deficiency that can be compensated by micronutrient supplementation. Among the nutrients implicated in viral infection, selenium (Se) has an important role in antioxidant defense, redox signaling and redox homeostasis. Most of biological activities of selenium is performed through its incorporation as a rare amino acid selenocysteine in the essential family of selenoproteins. Selenium deficiency, which is the main regulator of selenoprotein expression, has been associated with the pathogenicity of several viruses. In addition, several selenoprotein members, including glutathione peroxidases (GPX), thioredoxin reductases (TXNRD) seemed important in different models of viral replication. Finally, the formal identification of viral selenoproteins in the genome of molluscum contagiosum and fowlpox viruses demonstrated the importance of selenoproteins in viral cycle.

The possibility of increasing metabolism and resistance in an organism of animals under the influence of biologically active substances of natural origin is considered in the paper. In the current study, we investigated the effect of 40% ethanolic extract of common nettle (Urtica dioica L.) on hematologic indexes (hemoglobin concentration, erythrocytes and leukocytes content), protein metabolism (total protein, aspartate aminotransferase (AST), alanine aminotransferase activities (ALT)), glutathione metabolism (peroxidase (GP), glutathione reductase (GR) and reduced glutathione content (GSH)), antioxidant defense systems (superoxide dismutase (SOD), catalase (CAT)), and indicators of free radical processes (lipid hydroperoxidation products (LHP), TBA-active products and carbonyl groups of protein (CP)) in the blood and tissues of normal and adrenalin-stressed rats. White Wistar rats (male) with body weight 180–200 g were used in the experiments. The animals were divided into 4 groups (control and 3 experimental), each containing 7 animals. The animals of experimental groups D2 and D3 received 40% ethanolic extract of common nettle in a dose of 5 mL/kg of body weight during 4 weeks. After 29 days of the experiment, the animals of D1 and D3 groups were intramuscularly administered 0.1% solution of adrenaline hydrochloride at a dose of 1 mg/kg of body weight. One day after the administration of adrenaline, the animals were decapitated under ether anesthesia. The objects of the study were blood and homogenates of liver, heart, and kidneys of the rats. Our results have shown that adrenaline stress causes a decrease in the concentration of hemoglobin, LHP, SOD activity and increase in activities of AST, GP, GR, and GSH content in the blood of rats. Stress induced by adrenaline was accompanied by decrease in CP content, activities of SOD, CAT, and increase in the glutathione chain of antioxidant defense system in the liver of the animals while in the heart and kidneys, there was an increase in oxidative stress parameters and decrease in antioxidant enzyme activities (SOD, CAT, GP, GR). The administration of ethanolic extract of nettle caused an increase within the physiological range in the erythrocytes and leucocytes content, hemoglobin concentration, and normalization of protein metabolism (decrease in the activity of AST and increase in protein concentration) in the blood of the stressed rats. The activation of the antioxidant defense system (increase in activities of SOD, GP, CAT, GR) and inhibition of free radical processes (decrease in concentration of LHP, TBA-active products and CP) was observed in the tissues of animals of D2 and D3 groups. Our results suggested that using a complex of biologically active substances of the common nettle ethanolic extract prevents metabolic disorders and stresses of different etiology through the activation of the antioxidant defense system, the normalization of protein metabolism and stimulation of hematopoiesis both in normal and stressed rats.

Health indicators of the population depend significantly on the food quality and nutritional value. Simple carbohydrates excess of and lack of protein, dietary fiber, vitamins, minerals, antioxidants and other physiologically active substances increase the risk of socially significant disease progress. The development and production of mass-consumed products with high nutritional and biological value, including affordable non-traditional raw materials use, are promising areas of the food industry development aimed at improving the nutritional status of the population. The article presents the research results on the developed Noodle products recipes from non-traditional raw materials that meet modern healthy nutrition requirements, intended for dietary treatment and dietary prevention of people with overweight / obesity. The research aimed at expanding the range of macaroni products with these characteristics. As the main raw material, a man selected whole-wheat flour – new spelt flour, and as additional raw materials – buckwheat flour, broccoli and celery powders. The researchers found that the introduction of macaroni products from buckwheat spelt, broccoli and celery powders into the recipe had a multidirectional effect, reducing or increasing various indicators of its nutritional value. The changes range did not affect the overall characteristics. The satisfaction degree of the average daily need for food substances and energy when consuming a portion of 100 g for each sample of developed Noodle products allows them to be classified as functional products that are protein and dietary fiber sources, according to the requirements of the TR CU 022/2011.

The article provides brief information about cardiotonic, sedative, cytostatic, diuretic, and antibacterial effects of biologically active compounds of Adonis L. (Ranunculaceae) species. Chemical studies allowed to identify the cardiac glycosides, or cardenolides: or cardenolides: adontoxin, adonitol, adonitoxigenin, acetyldigitoxin and others. In scientific medicine, it is currently allowed to use Adonis vernalis L. Other types of Adonis have a similar chemical composition and are offered as substitutes for this official species, for example, Adonis apennina L. Many Adonis species have limited natural resources, and in some regions are rare, requiring conservation of their natural populations. The search for alternative sources of medicinal plant raw materials, based on this, is relevant. The experimental part of our research was carried out using the morphological and geographical method with the involvement of information on ecology and phenology. For the first time summarizes the diagnostic features of Adonis flora of Russian flora. Previously unknown structural features (shape and size of anthers) were identified that characterize the subgenera Adonanthe and Adonis. Taxonomic study of the genus Adonis of the Russian flora allowed us to determine its species composition, clarify its systematic affiliation, and nomenclature synonyms. 9 species were identified. Of these, 6 are perennials belonging to the subgenus Adonanthe, section Consiligo, which includes 2 subsections: Amurenses (2 species) and Vernales, which is differentiated into 2 rows: Apenninae (2 species) and Vernales (2 species). Subgenus Adonis is represented by 2 sections: Adonis (1 species) and Lophocarpa with sections Aestivales (1 species) and Dentatae (1 species). For all the considered species and varieties, the main distribution areas are given. A key has been compiled to determine the wild Adonis species distributed in Russia.

Несмотря на достигнутые успехи в диагностике и лечении, на сегодняшний день проблема хронического простатита у пациентов с доброкачественной гиперплазией простаты продолжает оставаться актуальной. Тем временем, выздоровление или же стойкая ремиссия хронического простатита наступает только у 30-35% больных, которые получают традиционное лечение. В патогенезе хронического простатита важное место занимают мембранопатологические процессы, которые обусловлены активацией перекисного окисления липидов и нарушением состояния антиоксидантной системы защиты. У больных с хроническим простатитом и доброкачественной гиперплазией простаты наблюдается существенное усиление процессов липопероксидации на фоне сниженной функциональной способности антиоксидантных систем защиты организма. Поэтому равновесие в оксидантно-антиоксидантной системе является важным звеном в поддержании гомеостаза и, в частности, при патологии предстательной железы, предопределяет включение в комплексное лечение средств антиоксидантного действия. Перспективным можно считать применение препаратов с высоким содержанием биофлавоноидов и антиоксидантных витаминов. Включение в комплексное лечение таких пациентов препарата Кверцетина приводит к сокращению сроков нормализации клинико-лабораторных проявлений заболевания благодаря восстановлению равновесия между перекисным окислением липидов и состоянием антиоксидантной системы защиты Despite the successes achieved in the diagnosis and treatment, to date, the problem of chronic progression in patients with benign hyperplasia of the growth continues to remain relevant. Meanwhile, recovery or persistent remission of chronic prostatitis occurs only in 30-35% of patients who receive traditional treatment. In the pathogenesis of chronic prostatitis, membrane-pathological processes take an important place, which are caused by the activation of lipid peroxidation and impaired state of the antioxidant defense system. In patients with chronic prostate and benign hyperplasia, a significant increase in lipoperoxidation processes is observed against the background of a reduced functional ability of antioxidant defense systems. Therefore, the equilibrium in the oxidant-antioxidant system is an important link in the maintenance of homeostasis and, in particular, with the pathology of the prostate gland, allows the inclusion of antioxidant drugs in the complex treatment. The use of drugs with a high content of bioflavonoids and antioxidant vitamins can be considered promising. The inclusion of such patients in the complex treatment of the drug Quercetin leads to a reduction in the normalization period of the clinical and laboratory manifestations of the disease due to the restoration of the equilibrium between the peroxidation of the lipid peroxidation system and the state of lipid peroxidation

The article presents experimental data on the state of the antioxidant system in red blood cells of white outbred rats 1 and 3 months after acute mercury nitrate poisoning with a semilethal dose. It has been established that this form of intoxication is accompanied by pronounced changes in the state of the antioxidant defense system in erythrocytes of poisoned animals (a decrease in the concentration of reduced glutathione, a decrease in the activity of superoxide dismutase and glutathione peroxidase, and an increase in the concentration of lipid peroxidation products).It has been shown that the mercury content in the blood of experimental animals remains elevated during the entire study period.The results obtained indicate the importance of impaired functioning of the antioxidant system in the implementation of long-term consequences of acute mercury poisoning. The reasons for the occurrence of these biochemical shifts and their role in the development of the long-term cytotoxic effects of mercury nitrate are discussed.
