Zinc content in blood plasma and brain tissue of rats was studied by analytic mass-spectrometry with inductively coupled plasma. In control (saline-treated animal) zinc content in plasma was 3.6±1.4 mg/ml, in the liver - 12.5±2.5 mg/mg, in the spleen - 10.9±4.1 mg/mg, in the brain - 8.7±3.0 mg/mg. After a single intraperitoneal injection of zinc donator acizolum (24 mg/kg) zinc content decreased in all examined tissues, especially in brain. After a course of sequential acizolum injections (seven administrations during two weeks) essential elevation of zinc content in blood plasma and tissues investigated was detected. The maximal increase zinc concentration in blood plasma and liver was detected in 15 h after the last acizolum injections. Selen, calcium, copper and iron contents demonstrated a more complex behaviour. The obtained data suggest that prolonged acizolum administration has a significant impact on the bioelements content, and this should be taken into consideration when this zinc donator is used as a drug.

The presented study is devoted to one of the urgent problems of the conservative treatment of chronic pancreatitis — relief of painful abdominal and dyspeptic syndromes. Polymorphism of the etiopathogenetic variants of the formation of pancreatic diseases naturally justifies the need for complex therapy, including secretolytics, antispasmodics medications and polyenzyme drugs. The use of Meteospasmyl in complex therapy effectively relieves abdominal pain and dyspepsia, modifies the composition of the intestinal microbiota and improves the quality of life in patients with chronic pancreatitis.

Zinc level in the blood plasma and brain of rats was studied by inductively coupled plasma mass spectrometry. Maximum amount of zinc was observed in the cerebellum (15.0±5.5 μg/mg wet tissue). Single intraperitoneal administration of a zinc donor acyzol (24 mg/kg) did not change the content of this element in the tissues. Repeated injections of acyzol (7 injections over 14 days) significantly increased zinc level in rat plasma and brain. This elevation was most pronounced in the forebrain (cortex and subcortical structures). The rise in zinc concentration in blood plasma correlated with its level in the brain.

Identification of workers who are at high risk and at low risk as a result of participation in the cleanup of the consequences of the accident at the Chernobyl nuclear power station ("liquidators") is important both for scientific research and for the medical care of the individuals involved. Using register data for 36,700 liquidators, the authors estimated the relationships between radiation doses and the following factors: time of arrival at the accident zone, irradiation conditions, and possible health effects following the exposures. The analyses took into account types of work (decontamination, cordon work, building); places and circumstances of work (inside or outside or with machinery); and the use of individual protection measures. Included in possible effects on health were changes in hematologic indexes, weakness, headache, dryness or tickling of the throat, cough, facial hyperemia, metallic taste, anorexia, nausea, vomiting, heaviness in the epigastric region, and instability of defecation. With the help of mathematical models, the rating for each factor was assessed, and on this basis the liquidators were subdivided into risk groups. For workers for whom dose information was not available, probable doses could be calculated. The three most influential variables were time of starting work, type of work done, and the number of health effects.

Since 2020, the world has been living in the COVID-19 pandemic caused by the SARS-CoV-2 virus. This situation is due to the high virulence and prevalence of the virus, which has reached epidemic proportions in recent years. Hemostasis disorders are the main marker and prognosis of the severe course of the disease. The virus in the body of a patient with COVID-19 triggers a pathophysiological chain reaction, which, in turn, will lead to the development of a cytokine storm, a disorder in the hemostasis system, and the development of multiple organ disorders. The purpose of the study: to determine and study the influence of various factors on the characteristics of hemostasis in patients with moderate and severe COVID-19. The object of the study were patients with moderate and severe forms of the disease. The following methods were used in the study: standard laboratory diagnostics and hair mineralogram. Results. Moderate and severe courses have clear laboratory markers, with a high probability of developing thrombotic complications, especially in conditions of deficiency of such minerals as zinc, selenium, iron, copper, bismuth, and aluminum, which have immunoregulatory, antioxidant, antiviral, and hemostatic properties, as well as reduce the risk of secondary infection. Conclusions. The results of the study suggest the importance of using minerals and emphasize the significance of using minerals in patients at the very beginning of the disease in order to strengthen the main physiological systems in case of laboratory-confirmed deficiency.
