The objective is to study the incidence of metabolic disorders and effects of obese genes in patients after acute and chronic intoxication with pesticides and to justify methods for evaluating their severity to optimize differentiated therapy and prevention. Material and methods. In 104 agricultural workers after acute poisoning with 2,4-D based herbicides, organophosphorus pesticides and synthetic pyrethroids, and 66 patients with chronic intoxication with pesticides in the initial period and a year later, parameters of oxidative stress, carbohydrate and fat metabolism were studied, depending on the development of toxic liver damage syndrome. In patients after acute poisoning with 2,4-D-based herbicides, imbalance of fatty tissue hormones — leptin, resistin, adiponectin and TNF-α — has also been studied. Conclusion. Dynamic observation has made it possible to establish that in those who have had acute and chronic intoxication with pesticides with toxic liver damage syndrome, metabolic disorders and effects of obese genes develop as the progression of hepatosteatosis develops. The increased level of fatty tissue hormones in the blood — leptin, resistin and TNF-α, at the background of a slight decrease in adiponectin levels in patients who have had poisoning with 2,4-D-based herbicides, allows predicting an increased risk of a progressive course of steatohepatosis and obesity, prevention of which is based on the long-term use of metformin and statins. Key words: metabolic disorders, effects of obese genes, imbalance of fatty tissue, acute and chronic intoxications, pesticides.

<em></em>Effects of phytopreparation from a plant of <em>Limonium gmelinii</em> were studied on livers of white breedless rats at chronic impact of cadmium sulfate and carbon tetrachloride. It was established the administration of cadmium sulfate during six months caused chronic hepatitis, while the simultaneous administration of preparation from <em>Limonium gmelinii</em> and cadmium sulfate did not result of destructive changes in a liver. Chronic intoxication of the animals by carbon tetrachloride during six months caused progressive postnecrotic cirrhosis. The simultaneous administration of phytopreparation and carbon tetrachloride caused postnecrotic fibrosis in the central part of hepatic lobule only. Not only dystrophic and necrobiotic processes also numerous inflammatory cell infiltrates were observed in hepatic parenchyma of animals which were treated by cadmium sulfate and carbon tetrachloride, while it was not observed at animals which were medicated with phytopreparation. Thus, on the basis of the data was concluded about hepatoprotective action of phytopreparation from<em> Limonium gmelinii</em>.

The research objective was to evaluate the morphofunctional state of the adrenal glands in laboratory animals in conditions of acute and chronic intoxication with cypermethrin. Studies were performed on 140 male rats of the Wistar line. To simulate an acute intoxication cypermethrin was single injected into the stomach in a dose of half of LD50 followed by observation of the animals for 30 days. In the study of chronic intoxication cypermethrin was administered to rats in a dose of 1/100 of LD50. The experiment has lasted for 120 days.At the initial stage of the experiment the acute intoxication of rats with cypermethrin caused hyper- and then hyposecretion of adrenocorticotropic hormone. The content of progesterone in the blood serum and adrenal tissue decreased in animals. During the first three days after the poisoning there was an increase in the concentration of corticosterone in the blood serum. To the end of the 7th day the concentration of this hormone in adrenal tissue decreased sharply and did not reach the control background after a month. Chronic intoxication with cypermethrin caused hypersecretion of adrenocorticotropic hormone for two months with the subsequent normalization of its level in the blood. The disturbance of progesterone synthesis in the adrenal glands during chronic intoxication is indicated by fluctuation of its concentration in blood 30 days after the start of the experiment. There was found high level of corticosterone in blood and adrenal glands for two months, and then it decreased to a control level. Morphological criteria for amplification and then suppression of adrenal function are the dimension of endocrine cells and their nuclei, the intensity of cell vacuolation suggesting the degree of lipids accumulation, and the severity of blood filling in the vessels of the beam and reticular zones.

Результаты исследования в опыте in vivo подтвердили снижение негативных последствий при хронической интоксикации животных для образцов настойки сладкой крепостью 20 %, содержащей черносмородиновый спиртованный морс, по сравнению с раствором этилового спирта аналогичной крепости. The results of the study in the in vivo experiment confirmed a reduction in the negative consequences of chronic intoxication of animals for samples of tincture with a sweet strength of 20 %, containing blackcurrant alcoholic mors, compared with a solution of ethyl alcohol of a similar strength.

Organophosphorus compounds (OPC) have been known for about 90 years: drugs and pesticides, poisons causing paralysis, convulsions and death in case of acute poisoning and leading to cancer, malformations and cognitive impairment in case of chronic exposure by doses that do not cause acute intoxication. Despite the existing measures, deaths due to OPC poisoning are recorded annually. The problem of children development after any poisoning even with small doses of these substances is especially urgent. Modern technologies provide new perspectives for the analysis of chronic intoxication by OPC, prognosis of acute poisoning severity and long-term health consequences. Research of miRNA and metabolomics came to the first place among the scientific approaches to the study of the body’s response to various external stimuli, including OPC poisoning. New methods are being developed to prevent the effects of poisoning based on stabilized bacterial enzymes, as well as modified miRNA.

1 A dithiol chelating agent-2,3-dimercapto-1-propane-sulphonate (DMPS)- may be administered in acute or chronic intoxication with certain heavy metals (e.g. cadmium, cobalt, lead) that may cause cardiotoxicity. 2 DMPS can act as a depleter of physiologically important elements (e.g. potassium, magnesium, calcium) in various tissues including cardiac one. The possibility of subsequent alteration in cardiac function cannot be excluded. 3 Changes in the myocardial concentration of the abovementioned elements at the end of the experiment and cardiac function were studied during repeated I.V. administration of DMPS as single doses of 50 mg/kg/ week for 10 weeks in rabbits. Biochemical, haemato-logical and histological examinations were also performed. 4 Most of the measured parameters were not affected by the repeated administration of DMPS. A significant decrease in magnesium and a near significant decrease in calcium in cardiac muscle was not accompanied by functional or morphological changes. It is still suggested, however, that care should be taken in using DMPS for treating patients with cardiotoxicity as a result of poisoning with heavy metals.
