[Effect of parenteral nutrition on the nucleic acid content in normal rat tissues and in thyrotoxicosis]

The content of nucleic acids in tissues of healthy animals and those suffering from thyrotoxicosis was studied as affected by parenteral administration of amino acid mixture of moriamine S-2 and casein hydrolysate. The content of RNA in the skeletal muscles, heart and liver is established to change considerably under the effect of nitrogenous media. With administration of moriamine S-2 or caseine hydrolysate the higher level of RNA in tissues with thyrotoxicosis, is normalized, especially in the skeletal muscles. The character of changes depends essentially on properties and composition of the administered preparations.
