[Effect of nitrogens parenteral nutrition on the amino acid spectrum of the blood and liver in thyroxine poisoning].

The effect of nitrogen parenteral nutrition on the blood and liver amino acid spectrum was studied in white rats with experimental thyrotoxicosis. The content of free amino acids in the blood plasma and liver was shown to be considerably increased in thyrotoxicosis in the presence of protein starvation. Injection of an amino acid mixture containing polyamin and improved casein hydrolysate for 7 days favoured the normalization of the content of most free amino acids in the blood and liver but did not completely eliminate their imbalance.
