[Metabolism and content of proteins in rat tissues under the effect of sodium ribonucleate in experimental hypercorticism].

Experimental hypercorticism induced by multiple injections of ACTH-zinc-phosphate inhibits the incorporation of 1-14C-alanine and 3H-methionine into proteins of the liver, spleen, musculus quadratus femoris, blood and nuclear plasma, mitochondria, microsomas and cytosol of the liver as well as decreases the protein content in them. Under the effect of ACTH-zinc-phosphate in combination with enteral administration of sodium ribonucleate, the deviations from the normal level in the incorporation of the labelled amino acids into proteins and in the protein content of the tissues under study are less pronounced than under the effect of the hormone only. An opinion is advanced that enteral injection of sodium ribonucleate may be more preferable than parenteral administration of this preparation with hypercorticism under clinical conditions.
