Potential difference across the pyloric antrum
American Journal of Physiology-Legacy Content, 1959 Previous work has shown the presence of a potential difference (PD) across the fundic portion of the stomach and a smaller PD across the pyloric antrum. All of the reported measurements on the pylorus have been performed with in vitro techniques.

THE INHIBITORY INFLUENCE OF THE PYLORIC ANTRUM ON GASTRIC SECRETION IN DOGS
Australian Journal of Experimental Biology and Medical Science, 1976 SummaryThe effect of denervation of the pyloric antrum and of subsequent vagotomy on the secretory responses of an innervated or a denervated gastric‐pouch in the dog to histamine and pentagastrin was determined. The increased sensitivity of the gastric pouch to stimulation after these procedures is in keeping with the concept that an inhibitory reflex

The G Cell Population of the Pyloric Antrum of the Cat
Digestion, 1975The method used in this study to quantify the G cell population of the cat is similar to the technique used for measuring the parietal cell mass in the stomach of rats and man. The method may be used on the human antrum. Mucosal sampling technique and immunofluorescence methods are described. The method is reproducible.

Distension of the Pyloric Antrum as a Stimulus for Gastrin Release
Archives of Surgery, 1970In their classic paper published in 1925, Lim et al first demonstrated that distention of the stomach stimulated gastric acid secretion. 1 Almost three decades later the important site for distention was found to be in the pyloric antrum and the mechanism involved was defined as release of the hormone, gastrin.

Inhibition of Vagally Stimulated Gastric Acid by the Pyloric Antrum
American Journal of Physiology-Legacy Content, 1958It has been previously demonstrated that gastric acid production of antral and intestinal origin is inhibited by acidification of the antrum. In this experiment a vagally innervated gastric pouch (Hollander) and an excluded antral pouch were constructed in four animals, two of the antral pouches being vagally innervated and two denervated. The gastric

Immunohistochemistry and morphometry of gastrin cells in the rat pyloric antrum during starvation
Anatomy and Embryology, 1986The gastrin cells (G cells) in the rat pyloric antrum after 7, 14, 21 and 28 days of starvation were investigated by immunohistochemistry and electron microscopy. In the peroxidase anti-peroxidase method for light microscopy, gastrin immunoreactive cells during starvation markedly decreased in number and size.

Benign Lesions of the Pyloric Antrum Simulating Carcinoma
The British Journal of Radiology, 1959Deformities of the pyloric antrum seen at one hospital over a period of five years were reviewed. In seven cases the deformity had been assumed to be due to an annular carcinoma but was found to be due to a benign condition. The radiological features of these cases and of the cases of carcinoma were compared.
