STUDYING POSSIBILITY OF USING VEGETABLE PHENOLIC COMPOUNDS TO PREVENT DAMAGE TO MEAT PRODUCTS

Posted in 2020, BIOLOGY, Issue № 03(93) March 2020 | 0 comments

The paper discusses the results of studies of the antioxidant activity of water extracts obtained from various parts of the plants of the family of Lamiaceae (Labiaceae) – field mint, garden mint, lemon balm, purple basil. It was found that water extracts from plants of the family Lamiaceae – field and garden mint, violet basil, and lemon balm can be used as safe antioxidants in the technology of vegetable oils and fat-containing products, such as minced meat. It was shown that the extracts from violet basil have the highest antioxidant activity, and the extracts of garden mint have the least activity. The effect of the number of plant extracts on meat safety was also studied.

The extracts from plants of the Lamiaceae family containing phenolic compounds of various classes are not inferior to synthetic antioxidants in their antioxidant activity. Studies conducted on the feasibility of using extracts from some plants of the family of Lamiaceae as antioxidants for fats and fat-containing products show that these extracts can be used to prevent or slow down oxidative processes, leading to a decrease in nutritional value and shelf life of food products.

COMPARATIVE ANALYSIS OF SOIL AND VEGETATION IN DALNIYE ZELENTSY VILLAGE AND CITY AREA OF MURMANSK

Posted in 2020, BIOLOGY, Issue № 03(93) March 2020 | 0 comments

This paper briefly presents the description and comparative characteristics of soils selected in 2019 at eight sites near the Dalnie Zelentsy village (East Murman) and on the territory of the city of Murmansk. It was revealed that the vegetation at the sites is represented by typical tundra species, subjected to anthropogenic impact and succession. Most soils are acidic Al-Fe-humus peaty podzols. By granulometric composition, all soil samples are sandy loam. Soil organisms live mainly in the upper organogenic horizon. Ciliata is the basis of soil biocenosis. The most common infusoria are the genera Colpoda, Stylonychia and Oxytricha sp. A study of the vegetation, thickness, and structure of the soil profile, and an assessment of the contemporary biodiversity of the protist fauna, may be important for monitoring the soil cover and determining the direction of soil processes.

ONTENTS OF LIPID-HYDROCARBON COMPLEX COMPONENTS IN MOLLUSCS IN SEVASTOPOL OFFSHORE STRIP (BLACK SEA)

Posted in 2020, BIOLOGY, Issue № 03(93) March 2020 | 0 comments

The offshore strips of coastal cities are of a great economic and recreational importance. They concentrate pollutants from both a coast and a sea, while at the same time providing the most significant contact of people with the marine environment. An important role in the interaction with pollutants belongs to coastal overgrown communities of macrophytes. As for the Sevastopol region, brown alga Cystoseira barbata (Stackh.) C.Agardh (1920) forms the vast underwater marine growth; its thalli are inhabited by various representatives of gastropods and bivalves, such as Rissoa splendida (Eichwald, 1830), Bittium reticulatum (da Costa, 1778), Gibbula divaricata (Linnaeus, 1758), Tricolia pullus (Linnaeus, 1758), Parvicardium exiguum (Gmelin, 1791), Mytilaster lineatus (Gmelin, 1791). The paper presents data on the content of total lipids and petroleum hydrocarbons in these mollusks. The content of total lipids in mollusks was determined by a color reaction with a phosphovaniline reagent followed by densitometry, and petroleum hydrocarbons by infrared spectrometry. The results of the studies allow us to recommend the most common mollusks Rissoa splendida living on the Cystoseira as new indicator species for assessing low levels of oil pollution in the offshore strip of the Black Sea coast of the Crimean peninsula. At the same time, these hydrations can be used to assess the microbiological flows of petroleum hydrocarbons in predicting the environmental consequences of oil pollution of coastal waters.

ROLE OF CENTRAL DOPAMINE IN BEHAVIORAL SUPPRESSION PROCESSES OF RATS DURING DAILY TESTING

Posted in 2020, BIOLOGY, Issue №2(92) February 2020, БИОЛОГИЧЕСКИЕ НАУКИ | 0 comments

According to the results, it is found that with a daily six-day testing of female rats in an open field, a significant motor deprivation is observed starting from the third day of the experiment. At the same time, the anxiety level of animals remains relatively stable, therefore, the anxiety factor cannot be the reason of the inhibition of motor activity. The blockade of monoamine oxidase-B by selegiline (intraperitoneal administration at a dose of 2.5 mg/kg 1.5 hours before testing) slightly changes the direction and severity of inhibition of motor activity of female rats and from the third day, the dynamics of changes in the behavioral activity of animals in the control and experimental groups completely coincide. Therefore, central dopamine is not able to prevent the suppression of these characteristics in a concentration that forms 1.5 hours after the administration of the monoamine oxidase-B blocker.

The authors believe that the main reason for the suppression of motor activity during daily testing of animals in the same experimental conditions, in the case of an open field, is the loss of motivation to study the test space. This is due to the fact that animals gradually memorize the experimental conditions and lose their research interest. From this point of view, we can say that central dopamine does not cause motor activation, but also does not contribute to the maintenance of research motivation, at least 1.5 hours after the blockade of monoamine oxidase-B.

FEATURES OF CHEMICAL COMPOSITION OF KHIBIN PLANTS AND LOVOZERO TUNDRA AND INTENSITY OF BIOLOGICAL ABSORBTION

Posted in 2020, BIOLOGY, Issue №2(92) February 2020, БИОЛОГИЧЕСКИЕ НАУКИ | 0 comments

The paper presents the analysis of the chemical composition features of the most typical vegetation representatives of the Khibin and Lovozero tundra. Special attention is paid to the ash content and gross concentration of a number of chemical elements in plants. The biological absorption coefficient (Kb) was calculated according to the Polynov’s and Perelman’s methods. It should be noted that such elements as K, Na, Ca, Mg, Si, P, Al dominate in the ash of plants. The geochemical specialization of various plant groups is manifested in an increased concentration of specific elements: Si, Ti, Cr – for lichens; Ca, Mg – for sinuous birch; Ca, Mg, P – for fluffy birch; K, Na, Mn, P – for Siberian spruce; Na, Si, Ti, Cr – for blueberries accumulating in plants. Their biological absorption coefficient is from 1.5-2 to n 100, include Ca, Mg, P, K, Na, Mn. Other elements are very poorly absorbed by vegetation; their Kb is less than 1.

Posted in 2020, BIOLOGY, Issue №2(92) February 2020, БИОЛОГИЧЕСКИЕ НАУКИ | 0 comments

The goal of this work is to add cover-ground and creeping plants to the collection of ornamental plants of the Polar Experimental Station, the VIR branch, with some locally cultivated and wild forms. Greening the urban areas of the Murmansk region requires expanding zonal assortment of ornamental plants. A systematic scientific work has begun at the Polar Experimental Station, a branch of VIR, aimed at introducing decorative herbaceous perennials and shrubs in 2017. At present, a promising collection fund of ornamental plants has been formed from 217 samples (167 species) of decorative crops from 42 families, including 131 samples of perennial herbaceous plants (77 genera), 57 – ornamental shrubs (10 genera), 8 – woody plants (4 genera). The range of wild plants they currently have at the Polar Experimental Station includes cover-ground and creeping species of herbaceous perennials, which is an important factor for equipping flower gardens of urban landscapes. Further expansion of the collection of ground cover and creeping plants is planned, based on the introduction of decorative representatives from the local flora of the Kola Peninsula, as well as the samples of botanical gardens and nurseries close to the climatic conditions of the Polar Experimental Station of the VIR branch [2].
