title: [Nucleic acids in the tissues of white rats with toxic liver damage following protein starvation and parenteral nitrogen nutrition].
abstract: The authors studied the content of nucleic acids in the tissues (the skeletal muscle and myocardium, the liver) in albino rats with toxic affection of the liver caused by ccl4, in protein deficiency and parental administration of amino acid mixture of moriamin S-2 and "improved" caseine hydrolysate. Protein deficiency in albino rats with toxic hepatitis was accompanied by a considerable increase of RNA and DNA in the skeletal muscle and the myocardium with a simultaneous reduction of their level in the liver. The RNA/DNA ratio changed. The RNA content in the hepatocytes diminished on account of reduction of the nuclear RNA fraction closely bound with chromatin. Parenteral administration of nitrogen preparations led to normalization of the nucleic acid content in all the tissues under study.
