For many years it has been speculated that the physiological function of Brunner's glands was to secrete mucus to protect the proximal duodenum from the corrosive effects of acidified gastric juice. However the control of Brunner's gland secretion remains an enigma. Some evidence exists which indicates both cholinergic and adrenergic innervation of these glands, but current consensus weighs heavily in favor of a hormonal stimulus for glandular secretion. This is based in part on evidence obtained from denervated Brunner's gland pouches following a feeding stimulus. a number of hormones and hormone-like substances have been investigated as possible mediators in this secretory response, however, no specificity was ever demonstrated. The inability to pinpoint a given substance as a common mediator can be attributed to the fact that most active agents employed also affect duodenal motility. We present evidence that Brunner's gland secretion can be observed to be a diphasic response. The initial, transient response is always observed in the presence of increased duodenal motility. The sustained response does not require duodenal motility and is probably hormonally mediated.
