Introduction. Scientists from Horbachevsky Ternopil National Medical University, Ternopil, and various countries, including state laboratories, have thoroughly studied the biological significance of copper and zinc ions in the body for many years. Nevertheless, the value of the shortage or excess of these metals and their compounds in the body remains mostly underestimated for health. Purpose of work: to study the pathogenesis of traumatic disease occurring due to an imbalance of copper and zinc in the body. Methods. Bibliosemantic and analytical methods were used. A literature search was conducted for the following queries as zinc, copper, heavy metals, negative impact. The investigation was performed with PubMed, Scopus, Web of Science, and Google Scholar for various articles. All publications have been analyzed and included in this review. The importance of these metals’ lack or excess and their compounds in the body remains mostly underestimated. Features of the pathogenesis of many diseases occurring due to imbalance of copper and zinc in the body have also been unexplored. The traumatic disorder was no exception, as this was not considered in experimental and clinical medicine. Conclusion. From the analysis of the available scientific literature, no messages were found about the features of the course of traumatic disease in conditions of excessive intake of copper and zinc ions in the body. We can only assume that a violation of the functional ability of the liver, lungs, brain and other organs that occurs against the background of heavy metal ion damage creates an unfavorable background for the occurrence of a serious injury.
Introduction. Given the significant prevalence of lead in the environment, research in this area has significant social and economic importance. Lead compounds are characterized by high toxicity and increased ability to cumulate in ecosystems, humans, and animals. Lead enters the human body with food, drinking water, atmospheric air, and smoking. Lead causes pathological changes in the nervous system, blood-forming organs, kidneys, etc. Materials and methods. The experiments were carried out on four groups of white female rats, each included seven animals, weighing 150-200 g. The first group of animals was a control. The second group consumed dechlorinated water from the city water supply, followed by lead acetate. The animals from the third and fourth groups drank the same water with sodium stearate and potassium stearate content in a dose of 1/250 LD50. After the 40th-day of the use of these waters, the animals were orally administered lead acetate at a dose of 7 mg/kg. The levels of lipid peroxidation biomarkers were studied by studying the content of diene conjugates (DC) and malondialdehyde (MDA) in blood serum, liver, and kidney homogenates. Results. The administration of 1/2 acetate LD50 to lead in experimental rats drinking water with stearates was accompanied by a significant increase in the DCs concentration and (MDA) in animals. Higher concentrations of LPO products were observed in the group of animals that consumed water from potassium stearate. Conclusions. 1. With the oral administration of lead acetate against the background of drinking water containing stearates at a dose of 1/250 LD50, an increase in lipid peroxidation indices was noted compared with the control group. 2. Higher concentrations of LPO products were observed in the group of animals consuming water from potassium stearate.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
