Abstract
Summary
1. Whole-body x-irradiation increases the percentage of liver glycogen in the fasting rat. At 24 hours after time of irradiation glycogen deposition was shown to increase with an increase in dose. 2. In rats exposed to 5000 r the percentage of liver glycogen was greater 48 hours after the time of irradiation than at 24 hours. In animals exposed to 550, 750, 1200 or 2500 r the percentage of liver glycogen was not greatly different at 48 hours and 24 hours after the time of irradiation. In no case did the liver glycogen levels in the irradiated rats equal or exceed that found in normal, fed rats. 3. Whole-body x-irradiation increased the blood sugar levels in fasting rats. Larger increases were noted at 48 hours after the time of irradiation than at 24 hours. At 48 hours after the time of irradiation the blood sugar level was, in every case, greater than that of fed, normal rats.
