EFFECTS OF NUCLEIC ACID PRECURSORS ON LIVER INJURIES

THE JOURNAL OF VITAMINOLOGY, 1967
AICA and AICA orotate were given in massive doses together with 20% casein diet to rats with liver injuries induced by a low protein, amino acid imbalanced diet, and the effects of both agents appraised.AICA orotate was apparently of value in recovering iodine numbers of fatty acids in liver lipids, increasing Palade granules and inhibiting fibrosis ...
