The beneficial effect of vagotomy in patients with duodenal ulc?ration is believed to depend on the halving of the gastric secretion of acid which follows the operation, and which persists for at least three years (Bell, 1964). It would be advantageo

The stomach converts food into fragments and then liquifies it before emptying it into the duodenum. Gastric emptying of liquid foodstuffs is so controlled that about 200 kcal/hr are delivered to the duodenum. The volume of the meal, its energy densi

1. Saline test meals (750 ml., 125 mM-NaCl) were given by tube into the stomachs of five subjects who were either sitting, lying on the left side, or lying on the right side. The gastric contents were recovered at 10 min. The rate of gastric emptying

1. Results were collected from thirty-three published and unpublished studies of gastric emptying. The volumes of the meals ranged from 50 to 1250 ml., and composition varied from pure carbohydrates to ordinary food. 2. From the published composition

Twenty-three subjects were given a total of 336 meals of 750 ml saline that was recovered at 5, 10, and 20 min to determine the intrinsic gastric emptying pattern. Minimal slowing of gastric emptying by duodenal receptors resulted from 120 mM NaCl. A

1. Five subjects took 210 test meals of 750 ml. water containing 30--300 m-molal glucose or glycine, or 15--150 m-molal diglycine, or plain water. 2. The greater the concentration of solute, the greater was the volume of original meal recovered from

The greater the concentration of energy (kcal/ml) in the gastric contents, the less is the volume rate of transfer per minute to the duodenum. Two sets of duodenal receptors are involved, one stimulated by the osmotic properties of the digestion prod

With oral and intravenous doses of metoclopramide there was no constant effect on the gastric emptying of test meals of glucose or sodium citrate, nor was secretion of acid by the stomach in response to test meals of glucose or sodium citrate affecte

1. Test meals of 750 ml. water containing a range of concentrations of hydrochloric, nitric, sulphuric, cyclamic (cyclohexylsulphamic), tartaric, L-ascorbic and citric acids were instilled into the stomachs of sixteen healthy subjects.2. The greater

Test meals of 200 ml containing acetylsalicylic acid or buffered acetylsalicylate were given to 19 healthy subjects. Studies were made of the rate of gastric emptying and the gastric absorption of acetylsalicylic acid. It was found that the buffered
