Abstract

Physiological and biochemical parameters of blood plasma of laboratory animals were evaluated when using, in addition to the main diet, a food substance with known biocorrecting properties - a probiotic emulsion administered orally, based on wheat germ oil and biomass of a consortium of lacto and bifidobacteria, including Str. thermophiles, B. bifidum, B. longum, B. adolescentis, L. acidophilus, L. plantarum, L. fermentum. The object of experimental studies was male and female growing white rats of the Wistar line in the amount of 60 individuals, comprising 2 experimental and 2 control groups of 15 individuals each. Evaluation of the average values of physiological indicators showed an increase in the horizontal and vertical motor activity of the white rats of the experimental group by an average of 16-18 % and 60-70%, an increase in the number of examined minks by 10-12 %, a significant decrease in the level of grooming and defecation. It was established that the clinical and biochemical parameters of the blood plasma of white rats were within the physiological limits. The concentrations of total protein, glucose, high and low density lipoproteins, alanine aminotransferase, aspartate aminotransferase by group differed slightly. It was found that the concentration of total cholesterol and LDL in the test groups of females and males at the end of the experimental studies decreased by 2.1-2.2 % and 4.1-5.8 %. The bilirubinaikreatinin concentration was slightly reduced in the experimental group of females and males by 1.1-1.3 % and 2.1-4.2 %, respectively. A significant increase in hemoglobin and red blood cells by 2.6-7.1 % and 4.8-5.1 % was recorded.
