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.

RESEARCH OF DEPENDENCE OF SENSOMOTOR INTEGRATION SPEED ON PRESENTATION TIME OF TOUCH THRESHOLD STIMULATION SYNCHRONIZED WITH PRESENT PHASE OF HUMAN EEG BACKGROUND RHYTHM

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

22 healthy subjects of both sexes showed that photostimulation synchronized with the ascending phases of alpha waves causes a statistically significant decrease in power in the alpha frequency range compared to the background. It was found that visual stimuli given in the descending phase of alpha waves lead to an increase in the power index of the frequencies of theta and alpha rhythms compared to the background. The dependence of the latent period of the sensorimotor reaction appeared to depend on the phase of the alpha-wave potential.

ORCHID (ORCHIDACEAE JUSS.) ON INZA POOL TERRITORY (CENTRAL PART OF VOLGA HILL)

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

Eighteen species from the Orchidaceae family were recorded on the territory of the Inza River basin, with 8 (Coeloglossum viride (L.) C. Hartm., Corallorhiza trifida Chatel., Cypripedium calceolus L., Cypripedium guttatum Sw., Epipactis palustris (L.) Crantz, Gymnadenia conopsea (L.) R.Br., Hammarbia paludosa (L.) O. Kuntre., Neottianthe cucullata (L.) Schlechter.) are known from herbarium collections and have not been discovered for the last 50 years; therefore they probably disappeared from this territory. New locations have been found for such species as Cephalanthera rubra (L.) Rich., Dactylorhiza maculata (L.) Soo, Dactylorhiza fuchsii (Druce) Soo, Epipactis atrorubens (Hoffm. ex Bernh.) Schult., Epipactis helleborine (L.) Crantz, Neottia nidus-avis (L.) Rich., Platanthera bifolia (L.) Rich.,Platanthera chlorantha (Cust.) Reichenb. Data on the number of coenopopulations of these species and the age status of individuals are presented. The annual ecological and floristic work aimed at studying the species of the Orchidaceae family will allow not only to assess the status of coenopopulations of species in previously known territories, but also to search for new growth sites in order to correctly assess the uniqueness of the territory and environmental measures.

MORPHOLOGICAL AND GENETIC FEATURES OF SOILS IN URUP ISLAND

Posted in 2019, BIOLOGY, Issue № 12(90) December 2019, БИОЛОГИЧЕСКИЕ НАУКИ | 0 comments

The paper presents the results of diagnostics and determination of the classification position of soils, which are located in the central part of Urup Island using the profile-genetic approach. The studied soils were formed on the coastal and slope areas of the island. The morphological, physical, and physicochemical characteristics of the studied soil profiles are provided as well. It was revealed that soils on a steep slope are polygenetic formations, but do not belong to layered soil types. The soils are light in terms of particle size distribution. A decrease was found in the content in depth along the profile of silicon oxide with a simultaneous increase of 1.5-2 times the number of one and a half oxides. The soils developed on the stretch of the sea terrace are layered. It was suggested that the physicochemical properties are influenced not only by plant associations, a low amount of organic carbon, but also largely by proximity to the slightly alkaline waters of the Sea of Okhotsk.

FUNCTIONS OF POSTPYROGENOUS COAL IN SOILS OF BORAL FORESTS OF FAR EAST

Posted in 2019, BIOLOGY, Issue № 12(90) December 2019, БИОЛОГИЧЕСКИЕ НАУКИ | 0 comments

Boreal forests are the most significant carbon sink among ground ecosystems. Forest fires occur annually on millions of hectares of the boreal zone. Millions of tons of carbon fixed previously by forests are lost in the form of carbon dioxide during combustion, as well as gigatons of post-pyrogenic coal. Being the most inert and long-term combustion product, coal has been attracting the attention of scientists since the mid-20th century, but its ecosystem function has not yet been fully understood. The goal of the study is to establish the effect of coal on soil properties, renewal of vegetation, and decomposition of organic matter in the boreal forests of the Far East. The studies were conducted in the northern part of the Amur Region in the larch forests of the foothills of the Tukuringra ridge. A positive correlation was established between the coal content in the soil and soil acidity (рНH2O) p <0.05, soil moisture, and mobile phosphorus content. Coal has a positive effect on pine regeneration. The coal content in the soil after the fire had no correlation with the content of ammonium forms of nitrogen (NH4+) and the number of larch seedlings (p = 0.664 and 0.5135). Coal accelerates the late stages of decomposition of thin larch roots. The background concentration of coal did not affect the decomposition of the roots, while the double average and maximum concentrations had a similar effect of accelerating decomposition. The research results show that under the conditions of postpyrogenic forests of the Russian Far East, coal performs a significant ecosystem function by accelerating the accumulation of stable forms of carbon in soils and the renewal of coniferous primary forests.
