“…The mechanism of the potent intestinal stimulation of gastric secretion has been little studied in man and most of the information available has been derived from animal experiments (Buxton et al, 1972;Debas et al, 1975;Konturek et al, 1976). It has been suggested that the intestinal phase of stimulation of gastric acid and serum gastrin could be accounted for by the alleged release from the gut of two hormonal substances, entero-oxyntin (Debas et al, 1975), which directly stimulates the oxyntic glands, and enterobombesin, which stimulates the release of antral gastrin and gastric acid secretion (Erspamer and Melchiorri, 1975).…”
