[Post-stress correlation of the functional activity of macrophages by tuftsin and its derivatives]

The effect of 15 day programmed neurotization on the functional activity of the peritoneal macrophages has been studied. The NBT-test and the adhesion measurements were used. The experimental neurosis resulted in the decrease of the macrophage functional activity and in leukopenia. Tuftsin did not restore the stress induced depression of macrophage activity but led to additional rise of the adrenal glands weight and to pronounced granulocyte-monocytosis. Pentapeptide analog of tuftsin gave the additional inhibition of NBT-activity of the macrophage. Heptapeptide analog favoured the restoration of the macrophage activity after neurotization and stimulated lymphopoiesis.
