RIA method was used in this study to determine immunoreactive beta-endorphin (ir-beta-EP) in gastric mucosa of patients with benign and malignant gastric diseases. The results showed that the content of ir-beta-EP in gastric mucosa in the peptic ulcer group was the highest (68 +/- 9.5 pg/mg wet weight tissue, P less than 0.01), while its content in gastric carcinoma was closely related to the degree of differentiation of the tumor, that is, in poorly differentiated carcinoma it was lower than that in well differentiated carcinoma (P less than 0.02), and was also lower than that in gastritis (P less than 0.05). At the same time, we found that beta-endorphin can markedly augment the 3H-TdR incorporation of lymphocytes (P less than 0.01). This effect was not blocked by naloxone.

We investigated the effect of phytohemagglutinin and the neuropeptide beta-endorphin on the in vitro lymphocyte proliferative response in patients with chronic ulcer disease and upper gastrointestinal bleeding or in remission, acute ulcer or hemorrhagic gastritis, and in healthy persons without upper gastrointestinal disease. We found that the addition of beta-endorphin produced a strongly enhanced proliferative response to phytohemagglutinin in lymphocytes from patients with chronic ulcer disease, and in particular from those with recent bleeding.

Cetraxate hydrochloride (cetraxate), ecabet sodium (ecabet), and sulpiride, which are cytoprotective drugs, have been used to treat peptic ulcers and acute or chronic gastritis. They are reported to improve mucosal blood flow in the stomach. One of the most important factors believed to cause gastric ulcers is mental and/or physiological stress. When people feel stress, the hypothalamo-pituitary-adrenal (HPA) axis is activated. Therefore, corticotropin-releasing hormone (CRH), adrenocorticotropic hormone (ACTH), and cortisol can be indicators of stress. We examined the effects of cetraxate, ecabet and sulpiride on the plasma levels of ACTH and cortisol under stress conditions by repetitive blood sampling. Venous blood samples were taken before and 20-240 min after a single administration of the drugs or a placebo. A single dose of ecabet caused significant suppression of increases in plasma ACTH-like immunoreactive substance (IS) levels at 90 to 120 min and cortisol levels at 240 min, compared with the response to placebo. Sulpiride only suppressed increases in plasma cortisol levels at 180 to 240 min, compared with the response to placebo. A single dose of cetraxate had no effect on plasma ACTH-IS and cortisol levels. Ecabet may have a modulatory effect on the HPA axis while sulpiride may have a partial modulatory effect on the HPA axis. These effects might be beneficial in stress-related disease.
