Burns (combustio) - tissue damage arising from thermal, chemical, electrical or radiation exposure. Burn disease – a complex violation of the organs and systems, developing due to extensive burns. The cause of burn disease is the loss of all types of the skin functions, loss of plasma, the collapse of red blood cells, as well as metabolic disorders. The probability of development, severity, and prognosis in this pathology are determined by the age of the patient, the General condition of his body and some other factors, but the leading role is played by the area of the lesion. 500 thousand animals are burned according to statistics in Russia for the year, and as a rule, mortality among burned animals is more than 11%. Treatment includes antibiotic therapy, infusion, and detoxification therapy, correction of all organs and systems. Treatment of burns of the first and second degree is most often limited to the local use of drugs that reduce pain sensitivity, promote faster tissue regeneration and help prevent infection, which leads to lengthening of healing processes and other complications. In the case of third and fourth-degree burns, regular thorough cleaning of the affected areas is also necessary, sometimes surgical intervention is required. Today, burns are widespread, so the search for effective treatments remains relevant. In this paper, we describe the etiology, pathogenesis of burns of small pets, the definition of the most effective and cost-effective method of treatment. The task of the research was also to determine the degree of burns and diagnosis of burns.

In this work, we investigated the relationship between the structural properties of materials based on multi-walled carbon nanotubes and the vital activity of bacteria E. Coli strain M-17. In the course of research using scanning electron microscopy and Raman spectroscopy, the structure of nanotubes was analyzed. Nanotube samples were tested for wettability. The effect of carbon nanotube samples on the growth of the bacterial culture of E. Coli strain M-17 using spectrophotometry was investigated. As a result, it was shown that samples containing more disordered defective nanotubes on the surface are more hydrophilic and also show worse biocompatibility properties for E. Coli bacteria.

In this work, the formation of defects during the ionic modification of carbon nanotubes was studied. It was shown that during the ionic modification of multiwalled carbon nanotubes, the defect formation mechanism is reduced not only to the formation of recoil atoms by ions, but also due to the thermal peak. It can be seen that the radial distribution function for the irradiated nanotube is significantly different from the radial distribution function of a heated 4000 K nanotube. In addition, disorder has a special character: in the case of ion irradiation, in contrast to heating.

The effect of hypersonic waves excited by a heterostructure based on a silicon wafer with natural oxide on the survival of planaria after their decapitation has been experimentally investigated. The aim of the work was to study the physical and biological factors affecting the regeneration of planarians. The main object of study was a model organism – planaria Dugesia Tigrina. The planaria were decapitated, and then they were monitored by their habitat for a week. Identification and counting of microorganisms, bacterial microflora inoculation, temperature, and pH control were carried out. To explain the mechanisms that occur under the influence of hypersound, a mathematical model of the passage of hypersonic waves through a thin layer of water near the glass-liquid interface was developed. In the process of regeneration after decapitation of the experimental group, it was found that in the experimental group exposed to hypersound, the survival of planaria was 60% higher than in the control. It was shown that in an aqueous medium along the glass-water interface, hypersonic propagation occurs with less attenuation than in the water column. This leads to a waveguide effect and improved transmission of hypersonic effects to the studied organisms.
