Effects of glucose-insulin-potassium infusion on glycogen levels in cardiac and skeletal muscles in rats.
The effects of loading with glucose-insulin-potassium on the glycogen contents of the heart and peripheral musculature were studied in rats. One group of animals was given intravenous infusion of high concentrations of glucose containing insulin and potassium for 3 days. A control group received the same volume of saline. The hearts and rectus femoris muscles were then analysed for levels of glycogen. It was found that loading with glucose-insulin-potassium induced a decrease in cardiac stores of glycogen while there were no changes in glycogen stores of peripheral musculature as compared to the control animals.
