A lower level of beta-endorphin (BE) was demonstrated in patients with both acute and chronic duodenal ulcer (P less than 0.01), while the basal level of bombesin (BO) in such patients did not differ from that in healthy subjects. The basal pancreatic polypeptide (PP) level was higher in both groups of patients, primarily in those with acute ulcer (P less than 0.01). A significantly negative correlation (P less than 0.001) between the levels of BE and BO, and between those of BE and PP, was found in healthy subjects. Similar interrelation was absent in ulcer patients.

The distribution of gastrin-, gamma-endorphin and somatostatin-producing cells in antral and duodenal mucosa was studied in biopsies from 26 patients with duodenal ulcer and from 13 controls by the immunohistochemical (PAP) method. The number of antral somatostatin-producing cells after dalargin treatment was significantly higher in comparison with controls and patients treated with antacids plus atropine. These changes may be connected with the antiulcer activity of dalargin, a new opioid peptide drug.

Proximal duodenal mucosal bicarbonate secretion is an important factor in the pathogenesis of duodenal ulcer disease. To examine the central nervous system regulation of duodenal bicarbonate secretion, an animal model was developed that allowed cerebroventricular and intravenous injections as well as collection of duodenal perfusates in awake, freely moving rats. The hypothalamic peptide corticotropin-releasing factor (CRF) and stress (physical restraint) significantly stimulated duodenal bicarbonate secretion. These responses were abolished by pretreatment of the animals with the CRF receptor antagonist alpha-helical CRF-(9-41), hypophysectomy, and naloxone. In contrast, blockade of autonomic efferents by surgical and pharmacological means did not prevent the stimulatory effects of stress and CRF. Intravenous, but not cerebroventricular, administration of beta-endorphin that produced plasma concentrations of beta-endorphin that were similar to those produced by exogenous CRF and stress significantly stimulated duodenal bicarbonate secretion. These results indicate that endogenous CRF released during stress and exogenously administered CRF stimulate duodenal bicarbonate secretion by release of beta-endorphin from the pituitary, thus, demonstrating a functional hypothalamus-pituitary-gut axis.

We investigated whether central pain mechanisms including the endogenous antinociceptive system are involved in functional abdominal pain--that is, abdominal pain without abnormal findings at routine examinations. beta-Endorphin, met-enkephalin immunoreactivity, and dynorphin immunoreactivity were measured in cerebrospinal fluid (CSF) from nine patients with long-lasting functional abdominal pain and nine pain-free controls undergoing minor surgery while under spinal analgesia. Furthermore, pain sensitivity was evaluated with an ischaemic pain test comparing 21 functional abdominal pain patients with two control groups: 1) 24 patients with organic abdominal pain due to duodenal ulcer, gallstone, or urinary tract calculi, and 2) 13 healthy pain-free controls. The CSF beta-endorphin concentration was significantly decreased in the functional abdominal pain group as compared with nine matched controls (P = 0.01). Met-enkephalin and dynorphin immunoreactivities were normal. This part of the investigation was suspended after nine patients had been tested, because of post-lumbar-puncture headache. With regard to pain sensitivity, no significant difference between the three groups was shown, but subdivision of the functional abdominal pain group showed that individuals with pain and no symptoms of irritable bowel syndrome (IBS) were significantly more sensitive to pain than functional abdominal pain patients with IBS and healthy controls (P = 0.04).
