Effect of x Irradiation on Increase in Rat Liver Tryptophan Peroxidase Produced by Adrenal Steroids.

Abstract
The increase in liver tryptophan peroxidase produced in adrenalectomized rats by injection of cortisone or hydrocortisone was no greater in animals exposed to 600 r X-irradiation than in unexposed animals. Thus, on the basis of this system, there is no evidence for an increased efficiency of utilization of glucosteroids in irradiated animals.
