Sulfhydryl Inhibition as a Mechanism in the Effects of ACTH and Cortisone.

Abstract
Suppression or partial inhibition of cellular enzyme systems thru sulfhydryl deprivation as produced by ACTH and cortisone is considered. The influence of cortisone on the spread of India ink - hyaluronidase mixtures in the skin of white mice was tested. The skin spread was restricted by cortisone; this inhibition of skin spread was quickly and completely reversed by reduced glutathione admd. intraperitoneally. It is suggested that sulfhydryl deficiency may be one common denominator in the effect of the C11 oxygenated adrenal steroids on their wide-spread enzyme system inhibition.
