in view of the experience that after short- or long-term oral administration of biguanides to rats no glycogenolysis in the muscle tissue occurs or even an increase of the muscle glycogen content and a high rate of incorporation of radioglucose into the muscle glycogen , the glycogen synthetase activity of skeletal muscle in a concentrated muscle homogenate and the effect of isoproterenol on glycogenolysis were investigated in normal rats after short-term oral administration of 1-butylbiguanide ( buformin ) .
