Nitrogen-sparing action of lipid emulsions for parenteral feeding of albino rats with thyrotoxicosis

The nitrogen-sparing action of lipid emulsions (intralipid and lipidin) during parenteral administration of casein hydrolysate was studied in 65 albino rats with thyrotoxicosis. If casein hydrolysate was given together with lipid emulsions and physiological regulators of metabolism the negative nitrogen balance was found to be quickly changed to positive, the free amino acid nitrogen level in the blood and tissues (skeletal muscle, heart, liver) fell, and the body weight of the animals increased.
