Endogenous corticosterone released in protracted immobilization stress fails to increase the activity of liver glycogen synthase, perhaps because of the inhibition of synthase phosphatase by phosphorylase a. It was also found, that in rats subjected to acute immobilization stress the stimulation of the activity of both synthase a and total forms by glucose administered i.v. is depressed. Finally, in rats fasting for 24 h a paradoxical augmentation by glucose of the stimulatory effect of glycogenolytic hormones released in acute immobilization stress on phosphorylase a activity was observed.
