Diabetes mellitus impairs the normal capacity of the liver to
synthesize glycogen. The decrease in hepatic glycogen observed
in this study may be due to lack of insulin in the diabetic state
and this type of results probably due to the inactivation of glycogen
synthetase system (Whitton and Hems, 1975). Treatment with
GMSt for 3 weeks significantly increased liver glycogen indicating
that the defective glycogen storage of the diabetic state was partially
corrected by the extract. The prevention of depletion of glycogen
in the liver is possibly caused by stimulation of insulin
release from existing pancreatic b-cells, which enhances glycolysis.
