“…Their influence provides a number of changes in the body, some of which have a positive effect, and some of which have a clearly negative effect. These effects have been monitored in humans [4], in productive animals [5] and in non-productive living organisms [6], as well as in different cell populations [7].…”

The development of human civilization inevitably leads to the development of production with increasing emissions of many chemicals into the environment. This is especially noticeable in relation to surface waters of fresh water bodies. A very alarming point is that the amount of toxic anthropogenic substances, including heavy metals, is growing every year and is increasingly disturbing the existing ecological balance. Plant organisms of water bodies are among the first to experience the effects of any anthropogenic pollutants and especially heavy metals and surfactants, the amount of which increases in the water of rivers and lakes. Very important in this is the complex of morpho-physiological adaptations associated with restructuring in the structure of chloroplasts. Changes in the content of photosynthetic pigments in plants of two species (Ceratophyllum demersum and Egeria densa) were assessed when they were exposed to very common technogenic substances (lead ions and a solution of anionic synthetic surfactants). In plants, there is a decrease in the activity of molecular transport, inhibition of H+-ATPase, leading to a decrease in the pH of the cytoplasm and activation of hydrolases, which enhance the breakdown of biopolymers. This leads to changes in the expression of individual genes and increased synthesis of a number of stress proteins. Under these conditions, the assembly of cytoskeletal elements is activated, the structures of membrane proteins and lipids change, the level of ATP decreases, free radical processes are activated and the intensity of photosynthesis is inhibited.

“…This ultimately leads to the development of oxidative stress and the appearance of prepathology and pathology [28]. During evolution, enzymatic defense mechanisms against the action of reactive oxygen species have been developed, including peroxidase, polyphenol oxidase, ascorbate oxidase and catalase [29]. At the same time, the reaction of these enzymes to negative chemical influences on the body from the environment remains poorly understood.…”

In the context of a gradual increase in anthropogenic environmental pollution, detailed environmental studies become relevant. It is very important in this regard to monitor the qualitative and quantitative aspects of the influence of the pollution process on various biological objects that receive the influence of substances entering the environment. Of great practical interest are the toxic effects of technogenic discharges on various hydrobionts and the main mechanisms of their development in macrophyte plants. In this regard, this work studied the influence of heavy metal ions, cationic synthetic surfactants and their combinations on the activity of the main antioxidant enzymes in tissues of Ceratophyllum demersum and Egeria densa. To do this, an experiment was conducted to assess changes in the freshwater macrophytes Ceratophyllum demersum and Egeria densa. The dynamics of the activity of antioxidant enzymes: peroxidase, polyphenol oxidase, ascorbate oxidase and catalase were studied. Their activity was assessed basally and in response to chemical stressors (100 µmol/l lead ions, 1% solution of cationic synthetic surfactants) individually and in combination with different exposures to toxic substances. The identified features of enzymatic activity in the tissues of aquatic macrophytes indicate different levels and power of their antioxidant protection. It becomes clear that the activity of antioxidant enzymes when plants are exposed to certain types of pollutants and their combinations is determined by the chemical nature of the pollutant, the mechanism of its action on the plant organism, the duration of exposure and the localization of these enzymes in cell compartments.

This paper shows the results of the study of the effect of temperature on the coagulation processes in the hemostasis of cows and calves. Purpose of the work: comparison of the results of the study of the indicators of the coagulation system of blood of cows and calves of the black-and-brown breed, obtained with the use of medical and veterinary coagulometer, taking into account the age of the animal and its body temperature. The study was conducted in the Vologda region of Russia. The following coagulogram parameters were analyzed: thrombin time, prothrombin time, activated partial thromboplastin time, fibrinogen count. It was found that at physiological temperature on a veterinary coagulometer in the plasma of cows there is a reliable increase in thrombin time by 2.2 times, decrease in prothrombin time by 32.5%, increase in activated partial thromboplastin time by 11.2%, increase in the amount of fibrinogen by 315.4%; in calf plasma - decrease of thrombin time by 7.8%, increase of prothrombin time by 6.2%, increase of activated partial thromboplastin time by 20.9%, increase of fibrinogen amount by 347.6% in comparison with the results obtained during standard incubation at 37°C. The correlation between hemostasis indicators and temperature factor in cows was noticeable (thrombin time, fibrinogen), in calves negative moderate for thromboplastin time, moderate for activated partial thromboplastin time and noticeable for prothrombin time and fibrinogen. The study of coagulation processes in cows and calves using a medical coagulometer led to the results that differ significantly from the reactions occurring in the organism at physiological body temperature. Taking into account the results of the study, it is possible to consider a veterinary coagulometer with the possibility of setting the necessary temperature as a device quite suitable for adequate assessment of hemostasiological parameters in cattle.
