[Influence of tissue emulsions on the phagocytic activity of the RES].

Radiometric, microbiologic, biochemical and morphologic investigations were carried out with a total of 95 guinea pigs and 20 rabbits in order to study the effect of the biogenic stimulants after Filatov on the phagocytic activity of the reticulo-endothelial system. Use was made of a tissue emulsion of swine embryos with biologic activity up to 160 per cent and a microbial stain - Escherichia coli 078. The labeling of the microorganisms was effected by means of 32P as obtained from Na2 H32PO4. It was found that the parenteral treatment of the animals with tissue emulsion after Filatov leads to the enhancement of the phagocytic activity and the lysing of the phagocytised bacteria by the elements of the reticulo-endothelial system by 7 to 10 per cent more than was observed with the use of control animals. The biogenic stimulants after Filatov activate the plasmocytic reaction of the body and the development of ribonucleoproteids in the parenchymal organs, and raise the level of properdin and gamma-globulins in the blood of the treated animals.
