“…TIR is found in the peptidoglycan of all known gram-positive and gram-negative bacteria. The main purpose of such drugs is to restore haemopoiesis, leukopoiesis, and immunity (Ushkalova et al, 2019). These drugs are widely used in medicine.…”

The number of studies related to detailed characteristics of immune system development in early stages of ontogenesis are directed to expansion of concepts of mechanisms of inherent and adaptive immunity in premature newborns. However, discrepancy in publication data and absence of clear conceptions about unique features of immune system in newborn piglets for different gestation periods have significant actuality for further investigation. The study was carried out to establish characteristics of phenotypic and functional characteristics of the immune cells and establishment of adaptive immunity in piglets. The antibody repertoire of sow has interested immunologists for decades, in part because of the ease with which large quantities of high affinity antibodies can be observed in serum, and into other fluids because of the presence of genetic variants for both light and heavy chain of all known immunoglobulin types. The integrative analysis of the cellular and humoral immunity in piglets during early ontogenesis carried out to clarify the exact mechanisms of the immune response modulation. Effectiveness and selectivity of the immunotropic chemicals application to regulate immune cell populations in piglets is presented. The progress in immune cell populations is regulated by the various cytokines production in the universal concentration-dependent manner. Furthermore, the development of the immune functions cross reacts with innate immunity mechanisms including anti-bacterial enzymes, epithelial barrier integrity in the both skin and intestine. The interaction between multiple components of innate immunity is a critic initiator of the dynamic changes in adaptive immunity. The natural resistance targets to the establishment of infection root and delays disease progression. The duration of the exposure to colostrum in important role in the dynamics of immune response as well as its efficacy. The chapter discusses the plural mechanisms so far proposed to be responsible for the modulation natural resistance.

Biocenosis management in the treatment of infectious and inflammatory diseases of the pharynx

The article deals with the treatment of acute inflammatory diseases of the oropharynx, which are an essential part of ENT pathology and are one of the main therapeutic and diagnostic tasks for an otorhinolaryngologist both on an outpatient basis and at the inpatient stage of medical care. It is known that most acute pharyngeal diseases have a viral etiology, do not have etiotropic treatment, and are treated mainly symptomatically. Nevertheless, many patients are irrationally prescribed systemic antibiotic therapy, which leads to an increase in global antibiotic resistance. There are known patterns of correlation between the practice of irrational prescribing of antibacterial therapy and peaks of antibiotic resistance in different countries. At the same time, local antimicrobials are often prescribed, many of which have a negative effect on the pharyngeal microbiome and contribute to bacterial superinfection. The appointment of this group of drugs is also unjustified, given the viral etiology of the pathological process. Acute infections of the upper respiratory tract, including the pharynx, often occur against the background of violation of mucosal immunity, which is the first barrier in the system of protection against respiratory infections. In the treatment of these diseases, it is important to use drugs that not only have antimicrobial properties, but also stimulate mucosal immunity and reparative processes. The solution in this situation can be the therapeutic use of various factors of local immunity that will not cause antibiotic resistance and bacterial superinfection, but will act synergistically with autologous factors of mucosal protection. This article provides an analysis of prospects of using one of such drugs in inflammatory pharynx diseases.

With the ongoing pandemic of the SARS-CoV-2 virus and the emergence of its new genovariants, along with the relevance of addressing the issue of vaccination of the population, the importance of non-specific prophylaxis, which is designed to reduce the viral load on the body and slow down the rate of virus spread, is increasing. The currently available research and experience in the use of antiseptic drugs or their combinations with the antimicrobial peptide lysozyme can be used for this purpose.Currently available research and experience in the use of antiseptic drugs or their combinations with the antimicrobial peptide lysozyme can be used for this purpose. Under conditions of lysozyme deficiency unhindered accumulation of non-hydrolyzed substrate, which is a constant source of autoantigens, is accompanied by immunity, metabolic and tissue homeostasis disorders. Analysis of a comparative study of different groups of antiseptics showed high virulicidal efficacy of cetylpyridinium chlorideCetylpyridinium chloride has an electrostatic effect on viral membrane lipids, causing their aggregation and dissolution, which leads to disruption of the integrity of the virus membrane, its interaction with mucosal epithelial cells and penetration into target cells, having a direct virulicide effect on SARS-CoV-2. An important factor of innate mucosal immunity is lysozyme, it has antiviral, antibacterial, antifungal and anti-inflammatory effects, normalizes microbiocenosis, restores immune system activity, increases mucosal barrier function. The combination of cetylpyridinium chloride and lysozyme hydrochloride has a dual antiviral effect, reducing the viral load on the body and enhancing the ability to control the spread of SARS-CoV-2 both from patients in the prodromal period of the disease or with its clinical manifestations, and from asymptomatic carriers with confirmed COVID-19 infection status.
