Introduction. Patients with vibration disease (VD) often have obesity and metabolic syndrome (MS), which increase the risk of developing type 2 diabetes, hypertension, and other conditions predisposing to a decrease in the quality and longevity of life. Genetic predisposition, overnutrition, environmental factors, including industrial ones, and others are factors influencing the formation of MS. The aim of the study is to identify associations between polymorphisms of the LEPR, PPARG and PPARGC1A genes, metabolic syndrome and obesity in VD patients caused by exposure to local vibration and the combined effects of local and general vibration. Material and methods. We examined 248 VD male patients exposed to local vibration and the combined impact of the local and general vibration. We have identified a subgroup of MS and obesity cases. The distribution of genotypes of the LEPR, PPARG and PPARGC1A genes in groups was studied. Results. In the group of VD and MS patients exposed to the combined effect of local and general vibration, the Gln/Gln genotype of the Arg223Gln polymorphic locus of the LEPR gene was less common, and the Arg / Gln genotype in MS cases was detected more often than in patients without it. Among patients with VD caused by exposure to local vibration with a waist circumference of more than 102 cm, the Gly / Ser genotype of the Gly482Ser polymorphism of the PPARGC1A gene was more common than among those with lower values of this indicator. Conclusion. In patients with VD caused by combined exposure to local and general vibration, the Gln/Gln genotype carrier of the Arg223Gln polymorphism of the LEPR gene may play a protective role in the formation of MS. Among individuals with VD caused by exposure to local vibration, carriers of the heterozygous genotype of the Gly482Ser polymorphism of the PPARGC1A gene may have a predisposition to the development of obesity. The obtained results are preliminary and require further research.

SummaryWe have demonstrated previously that fibrin enhanced plasmin formation by the vascular plasminogen activator was significantly impaired, when components isolated from the plasma of three uncontrolled diabetic patients (type I) were used to study plasminogen activation in vitro. In the present study it can be demonstrated that functional properties of the vascular plasminogen activators as well as of the plasminogens from the same three diabetic patients are significantly improved after normalization of blood sugar levels and improvement of HbAlc values. Most pronounced the Km of diabetic vascular plasminogen activator in the presence of fibrin returned to normal values, and for diabetic plasminogen the prolonged lag period until maximal plasmin formation occurred was shortened to almost control values. From these data we conclude that the observed abnormalities of in vitro fibrinolysis are not primarily associated with the diabetic disease, but might be secondary to metabolic disorders caused by diabetes.

Mycotoxicological monitoring of forages shows that the problem of mycotoxicosis has been relevant for several decades. Minimal doses of mycotoxins in feed lead to a decrease in milk productivity, increased sensitivity to infectious and non-infectious diseases. When several mycotoxins enter the body simultaneously, a synergistic effect develops, causing a significant increase in toxicity. Feed contaminated with several types of fungi and their toxins is dangerous for dairy cattle. It was found that the feed mixture contained the types of associations of Aspergillus spp. fungi + Fusarium; Aspergillus spp. + Penicillium spp. + Mucor spp; Fusarium + Penicillium; Mucor spp. + Fusarium + Ustilaginales. Pathogenetic features of metabolic and morphological changes in highly productive cows with polymycotoxicosis were studied. Feeding food contaminated with various metabolites of mold fungi leads to the development of signs of chronic toxemia in animals. Clinical manifestations are the development of diarrhea and dehydration, with a decrease in milk productivity. Metabolic disorders feature the development of an inflammatory process, metabolic acidosis, hyperfermentonemia, with an increase in the amount of creatinine and urea in the blood serum. Metabolic signs indicate the development of hepatorenal syndrome due to structural disorders of the liver and kidneys. Histological signs of polymicotoxicosis are intracapillary and hemorrhagic glomerulonephritis, hepatocyte micronecrosis, and proliferation of connective tissue stroma cells, which leads to the development of atrophic cirrhosis in the interstitial and circular phases.
