title: The effect of nandrolone, an anabolic steroid on putrescine metabolism in the mouse.
abstract: 1 The catabolism of injected 14 C-putrescine was studied in mice treated with nandrolone phenpropionate, an anabolic steroid. 2 The putrescine was rapidly metabolized; almost 50% of the injected radioactivity was recovered within 2 h as 14 CO2 in the expired air. 3 Considerable amounts of radioactive gamma-aminobutyric acid (GABA) and an unidentified compound were found in the kidney and in the urine in addition to radioactive putrescine, spermidine and spermine both in controls and nandrolone-treated mice. 4 Nandrolone elevated the concentration of endogenous putrescine in the kidney and urine, eightfold and twentyfold, respectively, and the concentrations of spermidine and spermine were also increased 5 after the injection of 14C-putrescine the incorporation of 14C into spermidine was significantly increased in the kidney of mice receiving nandrolone.
