EFFECT OF STRESS ON AMINO ACIDS AND RELATED COMPOUNDS IN VARIOUS TISSUES OF THE RAT

摘要

The composition of various amino acids and related compounds in the aorta, ventricle, atria, liver, kidney, pancreas, bronchi and adrenals of rats is presented. These patterns are qualitatively similar, but quantitatively different. Stress changed these patterns. In the aorta, alpha-aminobutyric acid and ammonia are decreased. In the ventricle, phosphoserine and red. gluthionine are increased; and ammonia, arginine, asparagine, carnosine, ethanolamine, glutamic acid, glutamine, lysine, phosphoethanolamine and taurine are decreased. In the atria, alpha-aminobutyric acid, aspartic acid, ethanolamine and red. glutathione are increased; and ammonia is decreased. In the liver, alpha-aminobutyric acid, cystine, isoleucine, red. glutathione, methionine and phenylalanine are increased. In the kidney, ethanolamine is increased; and beta aminobutyric acid, citrulline, cystathionine, glutamic acid, glycine and tryptophan are decreased. In the alpha-aminoadipic acid, ox. glutathione, glutamine, l-methylhistidine, phenylalanine, phosphoserine, tryptophan and valine are increased: and ammonia, cystine and aspartic acid are decreased. In the adrenal glands, anserine, glutamic acid, glutamine and ox. glutathione are increased; and arginine is decreased. In the bronchi, ethanolamine and beta-alanine are increased and alpha-aminobutyric acid and ox. glutathione are decreased. Thus, stress affects certain amino compounds but changes are substance and tissue specific and independent of changes seen in the plasma. [References: 22]
