A novel immunopharmacological biocompound

The publication is devoted to topical issues of experimental study of new biocompounds, based on the creation of a consortium of biological composite compounds – biological active substances (metabiotics) produced by strains 59T and 60T of saprophytic compounds of the genus Bacillus subtilis. These strains are very promising for the creation of hepatopicts, new medicinal substances, in the creation and development of a new pharmacological class of hepatoprotectors. Previous studies have shown the safety and hepatoprotective effect of biologically active drugs. It is worth noting that the very effective compounds are the produced biologically active substances – metabolites of bacterial origin, on the basis of which it seems appropriate to create a new class of drugs – metabiotics. The absence of vegetative probiotic cells in such compounds will reduce the additional immune load on the body. The combined use of these compounds provides a potentiated pharmacological effect. In this regard, it seemed appropriate, under the conditions of modeling toxic liver damage by carbon tetrachloride, to conduct an experimental assessment of the immunotropic effect of biologically active substances (BAS) on laboratory animals in order to confirm the effect on cellular factors of immunity. The purpose of the study was to study the effect of the combined use of dietary supplements produced by Bacillus subtilis microorganisms on indicators of cellular immunity in laboratory animals with toxic liver damage. Acute toxic hepatitis was reproduced in white laboratory rats with repeated intragastric administration of carbon tetrachloride. The comparison drug was a registered hepatoprotective drug – ursosan. The immunotropic effect was assessed using factors such as: phagocytic activity of macrophages and neutrophils (FA), NBT test, quantitative assessment of antibody-forming cells, T and B lymphocytes. As a result of the studies performed, reliable data were obtained on an increase in the number of T and B lymphocytes, antibody-forming cells, as well as an increase in FA, which confirms the activation of all parts of cellular immunity in conditions of acute toxic liver damage. The data obtained allow us to recommend the studied biocompound for the creation of new drug candidates of microbiological origin, hepatoprotective agents with immunotropic effects.
