[The functional activity of the macrophages in experimental intestinal dysbacteriosis in rats].
The study of the functional activity of macrophages in the peritoneal exudate and spleen of Sprague-Dawley rats was made under the conditions of dysbacteriosis caused by the administration of antibiotics (gentamicin and phenoxymethylpenicillin) and short-term food deprivation. The complex study of the key functions of macrophages, carried out on the same pool of cells, showed that under the conditions of antibiotic therapy the enhanced function of ingestion was accompanied by a decrease in all other investigated functional parameters of peritoneal macrophages: the intensity of protein synthesis, oxidation metabolism, the activity of lysosomal apparatus, 5'-nucleotide activity. In contrast to changes observed in macrophages after the administration of antibiotics, short-term food deprivation induced increased functional activity as shown by most tests used in this investigation (such as tests for the ingestion of sheep red blood cells, 51Cr, nitro blue tetrazolium, acridine orange, 5'-nucleotidase activity), but did not affect the intensity of protein synthesis in macrophages. The comparison of these results with the data obtained by the authors after the administration of an immunomodulating agent made it possible to regard short-term food deprivation, judging by its effect on the functional activity on macrophages, as an immunostimulating action.
