[Role of the thyroid gland in the effects of parenteral feeding]

In 82 albino rats with experimental thyrotoxicosis the assimilation of parenterally administered amino acid mixture of mori-amine S-2 was investigation. In thyrotoxicosis the assimilation of the amino acid mixture was found to be down. It is only a combination of mori-amine S-2 with vitamins, hormones and 6-methyluracil that facilitates the utilization of free amino acids by the tissues (this being borne out by a falling level of aminic nitrogen in the blood, skeletal muscles, heart and liver), persistently upholds the positive nitrous balance, prevents losses of the body weight and foces down oxygen consumption.
