Influence of Anabolic Steroids on Uptake of Alpha-Aminoisobutyric Acid by Levator Ani Muscle

W. Metcalf 1 and E. Gross 1

1 Department of Surgery, Albert Einstein College of Medicine, New York, New York

Two representative anabolicsteroids caused an increase in the uptake of agr-aminoisobutyric acid-1-C14 in the levator ani muscle of rats. The distribution ratio between that muscle and the plasma was increased fourfold by the administration of a synthetic anabolic steroid and twofold by administration of testosterone propionate. The determination of this increase may serve as an indicator for the myotrophic effect of anabolic steroids.
