A nasogastric tube was introduced under radioscopic control into the stomach of 20 normal persons. After fixing the tube, Rose Bengal I131 was injected intravenously. The individuals were then subdivided into two groups: A and B. A. Gastric fluid samples were aspirated for two hours in the ten cases in this group. B. In the other ten cases, a standard liquid diet was introduced via the nasogastric tube. Samples were also collected for two hours. The authors found differences between the samples during the first 90 minutes in both groups. Reflux values in group B were lower than in group A. After two hours, however, the results were the same.
