The article describes the results of the study of changes in the concentration of total protein and its fractions in the age range from 16 to 60 years. Concentrations of total protein and its fractions were studied in several age groups formed according to age periodization. Blood donors were the subjects. Biochemical blood analysis was performed using an automatic analyzer. Total protein, albumin and globulin fractions in blood serum were studied. According to the results of the study, it was found that there were age-related differences in some of the studied biochemical components. Mainly age differences were noted in the transition from adolescence to adulthood, the first period. There were no statistically significant differences between the subjects of adolescence and adulthood, the second period. Thus, age-related changes in total protein and its fractions in blood serum were largely absent in the age interval from 16 to 60 years.
The natural flora of the Vedensky biological reserve (Chechen Republic) has been studied, including 1543 species of vascular plants from 545 genera and 119 families. 12 large families (Asteraceae, Poaceae, Fabaceae, Lamiaceae, Brassicaceae, Rosaceae, Apiaceae, Caryophyllaceae, Boraginaceae, Scrophulariaceae, Ranunculaceae, Rubiaceae) including 492 species, and 20 large genera (Astragalus, Rosa, Orobanche, Medicago, Carex, Trifolium, Hieracium, Vicia, Allium, Stipa, Geranium, Festuca, Veronica, Artemisia, Viola, Poa, Centaurea, Euphorbia, Galium, Orchis) uniting 166 species are specified. By the dominant large families, the flora belongs to the Mediterranean type, and by the set of families of the head spectrum part and the prevailing geo-elements, it is Caucasian-Palaearctic one. Among the 7 florocoenotypes represented here, the rocky-talus and shrub-fringe ones prevail with significant participation of the meadow florocoenotype. More than half of the flora (54.53 %) is occupied by hemicryptophytes, and half as much as they – by terophytes (26.79 %); phanerophytes (9.2 %), cryptophytes (7.14 %), and hamephites (2.34 %) are less common. Herbaceous plants make up 88.46 %, trees and shrubs - 9.20 %, and subshrubs and dwarf shrubs - 2.34 % of the flora. The flora is rich in resource-useful species: 157 food, 288 fodder, 178 medicinal, 120 poisonous, 202 melliferous, 314 decorative, and 81 industrial plants.
For the first time, perennial materials on the Orchidacaeae Juss. family of Chechnya are summarizedб consisting of 15 families and 29 species. The largest genus in the family – Orchis L. is represented by 8 species. The article presents information that all members of the family are protected plants listed in the Red Book of Chechnya, Ingushetia, Dagestan, and the Stavropol Territory. Some species are not included in the list of plants to be protected, including those species that have underground tuberoids and can serve as a source of salep (for instance, Platanthera bifolia, P. chlorantha, Herminium monorchis, Traunsteinera sphaerica, Dactylorhisa incarnata, D. salina, D. urvilleana). In this connection, data on the resources of family members and the potential possibilities of their use as a medicinal raw material are of interest. We have carried out resource studies of the most common species of Orchis tridentata Scop, within the North Caucasus. The obtained data allow us to expand our understanding of the species role of Orchidaceae Juss family. Пoлyчeнныe дaнныe пoзBoляют pacшиpить пpeдcтaBлeниe o poли BидoB ceмeйcтBa Orchidaceae Juss. of the North Caucasus flora in the composition of vegetation cover.
Article provides a brief analytical review of studies of halophilic flora species of Tersko- Kumsk lowland area. The most important representatives are indicated, the adaptive properties of different halophyte groups are considered. Their resource value is noted (fodder, medicinal, melliferous, tannic, etc.). In the systematic aspect, the halophilic flora exhibits Mediterranean features, dicotyledons dominate in it, club-moss and horsetails are completely absent, ferns are minimally present. In the edaphic relation, most species of halophytes are obligate, confined to one type of substrate, and the vast majority of halophytes are confined to the steppe belt, the subalpine belt, the belt of upland xerophytes and the alpine belt are in descending order, least of all halophytes in the forest belt, individual species live in subnival belt.The question of the protection of solonchak vegetation and solonchak steppes as a peculiar ecosystems, with a distinctive landscape and original flora containing a highly specialized ecological group of plants, which testifies to the relationship of the nature of plants with the environment. Halophilic cenoses can serve as indicators of the soil, chemical composition and depth of groundwater.
