Application of Phagotherapy in the Treatment of Burn Patients (Review).

Treatment of patients with a burn injury is a complex process involving multicomponent multidirectional intensive therapy of the majority of organs and systems damaged by thermal effects on the skin, alternating with repeated surgical interventions aimed at removing nonviable tissues with subsequent plastic closure of wound defects. After the recovery from the burn shock, local infectious complications are considered to be the leading problem that decelerates the process of recovery and is the main cause of lethal outcomes. Since the skin integrity is broken, microorganisms penetrate readily into the internal environment of the human organism resulting in a septic state with multiple organ failure. A widespread and often uncontrollable use of antibacterial drugs in medical practice has led to the emergence of multiple drug resistance (MDR) in microorganisms. Introduction of drugs made on the basis of bacteriophages into practice is presently becoming increasingly important. This is confirmed by the growing interest in this field of pharmacology, the development of special programs aimed at studying the processes of phage and bacterial cell interaction. This review presents the main types of bacteria pertaining to MDR pathogens, principles of their classification, and the risk factors for infecting patients. The mechanisms of the selective action of phage particles on a bacterial cell and the possibility of using phage therapy in the treatment of burn injury (experimental and clinical data) based on the analysis of foreign literature are demonstrated as well as new positive properties of phages related to the changes in the macroorganism immune status caused by the interaction with bacteriophage particles.

[Concentration and purification of the measles virus using a 2-phase system of water-soluble polymers]. / Issledovanie kontsentrirovaniia i ochistki virusa kori s pomoshch'iu dvukhfaznykh sistem vodorastvorimykh polimerov.

A number of two-phase aqueous polymers based on dextran (mol. w. 500) and polyethylene glycol (mol. w. 1000, 4000, 6000) was studied. The two-step distribution of virus-containing tissue culture fluid in these systems was found to result in significant purification of measles virus from protein admixtures. The degree of virus purification was shown to depend on ratios of volumes and molecular weights of the polymers.
