The study was done upon the relationship between E.E.G. and carotid blood flow in the patients with dumping syndrome. And the results were as follows: 1. On dumping syndrome, the amplitude of α-wave of E.E.G. enlarged and the peak was found 15 miuntes after oral administration of 150 ml of 50 % glucose solution, but in the contral petients the E.E.G. anplitude was not changed. 2. The amplitude of α-wave increased by hyperventilation in dumper but there was no change in control group. 3. By the photic stimulation, the α-wave amplitude was not altered in dumper but no change was found in control. 4. By the sonic stimulation, the α-wave amplitude slightly decreased but in control it was largely decreased. 5. In dumping patients, every symptoms was happened at the same time of α-wave amplitude variation. 6. The change of α-wave amplitude was not related to the level of blood sugar. 7. The deterioration of base excess was found in dumping syndrome. This was caused by the alteration of the blood flow. 8. Blood flow in carotid artery decreased about 35% after the administration of glucose to canine jejunum. But it was not showed after saline administration only. Blood flow of femoral artery did not changed after glucose administration. 9. The relationship between the changes of cerebral blood flow and 5-HT level in: serum was not observed. 10. It was found that the change of α-wave was closely conuected with the carotid blood flow.
